Description

Technical Field

[0002] With the development of science and technology and the improvement of living standards, head-mounted display devices are being used more and more widely. Existing head-mounted display devices mainly include a host body and a fixing mechanism, wherein the fixing mechanism mainly includes temples and a headrest. The temples and the headrest generally use elastic straps, telescopic springs and other elastic and retractable mechanisms to achieve changes in their accommodation space to adapt to different head sizes. At the same time, their elastic characteristics can achieve clamping when worn to ensure wearing stability.

In this way, the returning speed of the wearing frame is reduced and the returning time is prolonged. Before the wearing frame returns to its original position, the user has taken off the device, thereby avoiding the phenomenon of hair being clamped and improving the user experience.

[0061] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0063] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0064] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0065] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0066] With the development of virtual reality and augmented reality technologies, more and more head-mounted display devices have been widely used. In actual applications, users often need to move around while wearing the head-mounted display device. Therefore, to ensure wearing stability, existing head-mounted display devices often have temples and a headrest connected to the host. The temples and the headrest clamp the head to ensure stable wearing.

[0067] In order to facilitate wearing, the temples and the back of the headrest are often connected by elastic parts such as elastic straps. The distance between the back of the headrest and the temples is adjusted by stretching the back of the headrest to facilitate wearing. In this solution, when the user takes off the device, due to the gap between the back of the headrest and the temples after stretching, the back of the headrest will quickly return to its original position the moment the user takes it off, causing the hair to be clamped between the back of the headrest and the temples, affecting the user experience.

[0068] Therefore, in order to solve the above problems, the present invention proposes a head-mounted display device, which includes:

[0069] Display assembly 100;

[0070] Connecting members 200 are provided on two opposite sides of the display assembly 100;

[0071] The wearing frame 300 is movably disposed on a side of the connecting member 200 facing away from the display assembly 100;

[0072] An elastic adjustment mechanism 400 connects the wearing frame 300 and the connecting member 200; and

[0073] The damping mechanism 500 is provided between the wearing frame 300 and the connecting member 200 to generate resistance when the elastic adjustment mechanism 400 drives the wearing frame 300 to move toward the connecting member 200 .

[0074] In the technical solution of the present invention, the head-mounted display device includes a display assembly 100, which is the main structure of the head-mounted display device. The two ends of the display assembly 100 are connected to a connector 200. The side of the connector 200 facing away from the display assembly 100 is provided with a wearing frame 300, wherein the wearing frame 300 and the connector 200 are connected by an elastic adjustment mechanism 400. The wearing frame 300, the connector 200 and the display assembly 100 together form a wearing space. When the user needs to wear the device, he only needs to pull the wearing frame 300, and then the elastic adjustment mechanism 400 is stretched, and the wearing frame 300 moves in a direction away from the connector 200, thereby increasing the wearing space and allowing the user to conveniently place his head in the wearing space. At this time, the external force is removed, and the wearing frame 300 is pulled by the elastic adjustment mechanism 400 to move in a direction close to the connector 200, and finally clamped in the user's head area, thereby completing the wearing; when the device needs to be removed, the device can be removed by simply pulling the wearing frame 300 in the same manner. However, since the wearing frame 300 quickly returns to its original position when the device is taken off, the user's hair may be clamped between the wearing frame 300 and the connecting piece 200, causing pain. To avoid this phenomenon, the head-mounted display device is also provided with a damping mechanism 500, which is provided between the wearing frame 300 and the connecting piece 200, and is used to generate a damping force when the wearing frame 300 moves toward the connecting piece 200; after the damping mechanism 500 is provided, when the user takes off the device, the wearing frame 300 moves toward the connecting piece 200. At this time, the damping mechanism 500 takes effect and gives the wearing frame 300 a damping force in the opposite direction of movement. After being acted upon by the damping force in the opposite direction, the wearing frame 300 slows down until it stops at the final initial position. In this way, the returning speed of the wearing frame 300 is reduced and the returning time is prolonged. Before the wearing frame 300 returns to its original position, the user has taken off the device, thereby avoiding the phenomenon of hair being clamped and improving the user experience.

[0075] Specifically, the head-mounted display device includes a display component 100, which is covered over the user's eyes when worn to provide a display image; the two ends of the display component 100 are respectively connected to connectors 200 for supporting the display component 100 when worn. In this embodiment, the connectors 200 are in the form of temples, which can be fixed or hinged to the two ends of the display component 100; a wearing frame 300 is provided at one end of the temple away from the display component 100, and the wearing frame 300 is connected to the connector 200 by an elastic adjustment mechanism 400. In this embodiment, the wearing frame 300 is 00 can be a rear headrest that is clamped at the back of the user's head when worn. The two ends of the rear headrest are respectively connected to the connecting piece 200 through an elastic adjustment mechanism 400, wherein the elastic adjustment mechanism 400 can be an elastic component such as an elastic strap or a telescopic spring. In this way, the connecting piece 200 and the wearing frame 300 can be elastically connected through the elastic adjustment mechanism 400. When the wearing frame 300 moves in a direction away from the connecting piece 200, the elastic adjustment mechanism 400 stretches. When the external force is removed, the elastic adjustment mechanism 400 retracts, and the wearing frame 300 will quickly retract to abut against the connecting piece 200. In order to solve the problem of hair being clamped due to the rapid retraction of the wearing frame 300, the head-mounted display device is also provided with a damping mechanism 500, wherein the damping mechanism 500 can be arranged between the wearing frame 300 and the connecting member 200. In order to simplify the structure, the fixing method thereof can be conventional means such as screws and rivets. In order to achieve the damping effect, the damping mechanism 500 can be a structure such as a cylinder with a damping function. In a specific application scenario, when the user wears the device, the wearing frame 300 is stretched away from the connecting member 200. At this time, the elastic adjustment mechanism 400 is in a stretched state, and a gap is formed between the wearing frame 300 and the connecting member 200. When the user takes off the product, the wearing frame 300 will quickly return to its original position under the elastic force of the elastic adjustment mechanism 400. At this time, the damping mechanism 50 0 works, applies a damping force opposite to the direction of its movement to the wearing frame 300, and the wearing frame 300 will gradually slow down under the action of the damping force, and finally slowly reach the original position and stop. In this process, due to the deceleration process of the wearing frame 300, its total return time will be longer than the market without the damping mechanism 500. In this way, before the wearing frame 300 returns, the user has already taken off the device, and then the wearing frame 300 returns slowly, thereby eliminating the hair clamping phenomenon and improving the user experience; in addition, it is conceivable that the damping mechanism 500 does not need to work during the entire process of the wearing frame 300 returning to its original position. For example, the damping mechanism 500 intervenes to decelerate in the final stage of the wearing frame 300 returning to its original position, as long as the user has taken off the device before returning to its original position.

[0076] Furthermore, the damping mechanism 500 includes:

[0077] a first push rod 510;

[0078] The first support member 511 is provided on one side of the first push rod 510 and has a cavity with an opening formed therein. The first support member 511 is provided with a throttle hole opposite to the opening, and the aperture of the throttle hole is smaller than the aperture of the opening.

[0079] A movable rod 512, one end of which is inserted into the cavity from the opening and the other end of which extends toward the first push rod 510, wherein the movable rod 512 is slidably connected to the cavity and abuts against the inner wall of the cavity; and

[0080] The first elastic member 513 connects the first supporting member 511 and the movable rod 512. When the elastic adjustment mechanism 400 drives the wearing frame 300 to move toward the connecting member 200, the first push rod 510 abuts against the movable rod 512, causing the first elastic member 513 to deform and generate elastic force, which compresses the air in the cavity near the throttle hole and generates resistance.

[0081] Among them, in the connecting member 200 and the wearing frame 300, one is provided with the first supporting member 511, and the other is provided with the first push rod 510.

[0082] This embodiment provides a first implementation of the damping mechanism 500 .

[0083] Specifically, the damping mechanism 500 includes a first push rod 510 and a first support member 511, wherein the shape of the first push rod 510 can be a rod-shaped component that is compatible with the overall structure of the device, and the first support member 511 can be a sleeve-shaped structural member. The first support member 511 has a cavity inside and an opening on one side, and the opening faces the side of the first push rod 510. The cavity has a side wall adjacent to the opening and a bottom wall away from the opening, wherein a throttle hole can be provided on the bottom wall, and the aperture of the throttle hole can be smaller than the aperture of the opening; a movable rod 512 is also movably provided on the first support member 511, and the movable rod 512 can be moved from the first support member 511 to the side of the first support member 511. The opening of the member 511 penetrates into the cavity, and the movable rod 512 abuts against the side wall of the cavity, and can slide in the direction close to or away from the first support member 511; in addition, the damping mechanism 500 is also provided with a first elastic member 513. In this embodiment, the first elastic member 513 is a telescopic spring, one end of the telescopic spring abuts against the first support member 511, and the other end abuts against an end of the movable rod 512 away from the first support member 511. When the movable rod 512 moves in the direction close to the first support member 511, the first elastic member 513 will be compressed and give elastic force to the movable rod 512 to prevent it from continuing to move. When the wearing frame 300 is pulled outward, the wearing frame 300 is away from the connecting member 200, and the first push rod 510 is away from the movable rod 512. When the wearing frame 300 returns to its original position, the first push rod 510 will abut the movable rod 512. At this time, the elastic adjustment mechanism 400 pulls the wearing frame 300 to continue to return to its original position, and the first push rod 510 continues to abut the movable rod 512, pushing the movable rod 512 to move in the direction close to the first support member 511. At this time, the first elastic member 513 will be compressed and transmit the elastic force to the movable rod 512 to prevent it from moving. In addition, since one end of the movable rod 512 extends into the cavity of the first support member 511, its end is in contact with the movable rod 512. The space between the bottom walls of the cavity gradually decreases. At this time, the air can only escape from the throttle hole on the bottom wall of the cavity. Since the aperture of the throttle hole is small, the speed of air escape is much smaller than the speed at which it is compressed. Therefore, the air in this area will be compressed, and the compressed air will produce a reverse damping force on the movable rod 512. In this way, the damping force and the elastic force of the first elastic member 513 will offset the force transmitted to the movable rod 512 by the elastic adjustment mechanism 400, thereby slowing down the speed of the movable rod 512, and then reducing the return speed of the wearing frame 300; and as the wearing frame 300 gradually returns to its original position, the force exerted by the elastic adjustment mechanism 400 on the movable rod 512 will gradually decrease, and the elastic force of the first elastic member 513 will gradually increase. When the two opposite forces reach a balance, the wearing frame 300 will eventually stop moving.In addition, it is conceivable that when the wearing frame 300 is pulled outward at this time, the first push rod 510 will be disengaged from the movable rod 512. At this time, the first elastic member 513 tends to restore the deformation, thereby pushing the movable rod 512 to move away from the first support member 511, and finally returning to its original state. That is to say, through the setting of the first elastic member 513, on the one hand, it is used to slow down the wearing frame 300, and at the same time, the movable rod 512 is returned to its original position, so that the damping mechanism 500 has the ability to automatically return to its original state.

[0084] Furthermore, the inner diameter of the cavity changes in a decreasing state from the end close to the opening to the end close to the throttle hole, and the movable rod 512 abuts against the inner wall of the end of the cavity away from the opening; and / or, the damping mechanism 500 also includes a rubber sleeve, which is sleeved on the end of the movable rod 512 facing the throttle hole; and / or, the damping mechanism 500 also includes a limit plate, which is provided at the end of the movable rod 512 away from the throttle hole, and the first elastic member 513 connects the limit plate and the support member.

[0085] Specifically, in order to ensure smooth resetting of the damping mechanism 500, the cavity of the first support member 511 can be specifically designed. For example, the inner diameter of the cavity can gradually increase from the bottom wall of the cavity to the opening, that is, the cavity is set to the shape of a trumpet. In this way, when the movable rod 512 gradually extends into the cavity, the gap between the movable rod 512 and the side wall of the cavity will gradually decrease, and the air escaping per unit distance will gradually decrease, and then the damping force will gradually increase. When the movable rod 512 is gradually pulled out of the cavity, the gap between the outer wall of the movable rod 512 and the side wall of the cavity will gradually increase, and the damping force will gradually decrease, thereby reducing the damping effect generated by the air when the first elastic member 513 pushes the movable rod 512 back to its position, thereby ensuring that the movable rod 512 can be smoothly returned to its position. In addition, to ensure smooth movement of the movable rod 512, a rubber sleeve can be provided on the peripheral wall of the end portion of the movable rod 512 extending into the cavity. In this way, the sliding of the rubber sleeve against the side wall of the cavity ensures smooth sliding while also reducing wear on the movable rod 512, thereby increasing its service life. To ensure the stability of the connection between the first elastic member 513 and the two, the outer peripheral surface of the first support member 511 can protrude outward to form a flange. The first elastic member 513 can be sleeved on the first support member 511 and abut against the flange. Correspondingly, a similar flange can be protruded outward at the end portion of the movable rod 512, and the first elastic member 513 can also abut against the flange. In this way, the first elastic member 513 can be restrained in place by the two flanges, ensuring the stability of the connection.

[0086] Furthermore, the damping mechanism 500 includes:

[0087] a second ejector rod 520;

[0088] The second support member 521 is provided with a slide groove, and the slide groove is provided with an escape opening;

[0089] The movable plate 522 is provided on one side of the second push rod 520 and is slidably disposed in the slide groove;

[0090] The second elastic member 523 is provided on a side of the movable plate 522 away from the second push rod 520 and connects the second support member 521 and the movable plate 522;

[0091] The damping cylinder 524 is provided on one side of the second support member 521 and is filled with damping oil;

[0092] The fan blade 525 is rotatably disposed in the damping cylinder 524; and

[0093] Gear 526, gear 526 and damping cylinder 524 are respectively arranged on opposite sides of the second support member 521, and the position of gear 526 corresponds to the avoidance opening, and gear 526 is coaxially connected to the fan blade 525;

[0094] When the elastic adjustment mechanism 400 drives the wearing frame 300 to move toward the connecting member 200, the second push rod 520 abuts against the movable plate 522, causing the elastic member to deform and generate elastic force, and driving the gear 526 to rotate, causing the fan blade 525 to stir the damping oil and generate resistance. Among them, in the connecting member 200 and the wearing frame 300, one is selected to set the support member and the damping cylinder 524, and the other is selected to set the second push rod 520.

[0095] This embodiment provides a second implementation of the damping mechanism 500 .

[0096] In this solution, the damping mechanism 500 includes a second top rod 520 and a second support member 521, wherein the shape of the second top rod 520 can be a rod-shaped member adapted to the overall structure of the device, and the second support member 521 can be a bracket for supporting other functional components. The second top rod 520 and the second support member 521 can be separately arranged on the connecting member 200 and the wearing frame 300, and the positions of the two can be interchangeable; a slide groove is provided on the second support member 521, and the slide groove extends in the direction of the second top rod 520, and a movable plate 522 is slidably connected to the slide groove, and the movable plate 522 can be moved along The slide moves in the direction of approaching or moving away from the second push rod 520; the movable plate 522 is connected to a second elastic member 523 on the side away from the second push rod 520, and the second elastic member 523 connects the movable plate 522 and the second support member 521. In this embodiment, the second elastic member 523 can be a telescopic spring, etc., and a baffle is provided on the end of the second support member 521 away from the second push rod 520. One end of the second elastic member 523 abuts the baffle and the other end abuts the movable plate 522. When the movable plate 522 slides toward the baffle, the second elastic member 523 will be compressed and give elastic force to the movable plate 522. The damping mechanism 500 further includes a damping cylinder 524, which has a cavity inside and is filled with damping oil. The damping cylinder 524 is provided on one side of the second support member 521. A fan blade 525 is rotatably connected to the cavity of the damping cylinder 524. The fan blade 525 can be arranged in multiples around a central axis. When the fan blade 525 rotates, the fan blade 525 will stir the damping oil in the cavity. The damping oil will give the fan blade 525 a viscous damping force to limit its rotation. A gear 526 is also rotatably connected to the outer wall of the damping cylinder 524. The gear 526 can be connected to the fan blade 525. 25 are connected by the same central axis; in addition, the end surface of the movable plate 522 facing the damping cylinder 524 can be provided with a convex tooth or a tooth groove, and the movable plate 522 is meshed with the gear 526 through the convex tooth or the tooth groove for transmission. In order to facilitate the connection between the movable plate 522 and the gear 526, an avoidance opening can be provided on the sliding groove of the second support member 521. The avoidance opening can correspond to the position of the gear 526. In this way, the gear teeth of the gear 526 can extend into the avoidance opening and be connected to the movable plate 522. When the movable plate 522 slides along the sliding groove, it will drive the gear 526 to rotate, thereby driving the fan blade 525 to rotate, generating a damping force;In actual application, when the wearing frame 300 is stretched outward, the wearing frame 300 is away from the connecting piece 200, and the second push rod 520 moves away from the movable plate 522. When the wearing frame 300 returns to its original position, the second push rod 520 will abut the movable plate 522, pushing the movable plate 522 to move toward the baffle on the opposite side. At this time, the second elastic member 523 will be compressed and transmit the elastic force to the movable plate 522 to prevent it from moving. In addition, since the movable plate 522 is engaged with the gear 526 for transmission, the movable plate 522 will drive the gear 526 to rotate, and then drive the fan blade 525 in the damping cylinder 524 to rotate. At this time, the damping oil in the damping cylinder 524 will give the fan blade 525 25 and its rotational direction opposite to the damping force, which will be transmitted to the movable plate 522 through the gear 526, thereby preventing it from approaching the baffle. In this way, the damping force and the elastic force of the second elastic member 523 will offset the force transmitted to the movable rod 512 by the elastic adjustment mechanism 400, thereby slowing down the speed of the movable plate 522 and thus reducing the return speed of the wearing frame 300. As the wearing frame 300 gradually returns to its original position, the force applied by the elastic adjustment mechanism 400 to the movable plate 522 will gradually decrease, while the elastic force of the second elastic member 523 will gradually increase. When the two opposing forces reach equilibrium, the wearing frame 300 will eventually stop moving. It is conceivable that when the second push rod 520 is about to disengage from the movable plate 522, the second elastic member 523 tends to recover its deformation, pushing the movable plate 522 away from the baffle, and finally returning to its original state. The provision of the second elastic member 523 can also realize the reset function of the damping mechanism 500.

[0097] Furthermore, the damping mechanism 500 also includes a third elastic member 527, which is arranged on the side of the movable plate 522 away from the gear 526 and connects the movable plate 522 and the second support member 521; the gear 526 is a ratchet, and the ratchet is provided with ratchet teeth on the circumference of the ratchet, and the movable plate 522 is provided with a ratchet groove on the side facing the ratchet; in the process of the elastic adjustment mechanism 400 driving the wearing frame 300 to move in the direction close to the connecting member 200, the ratchet groove cooperates with the ratchet teeth to drive the ratchet to rotate; in the process of the wearing frame 300 moving in the direction away from the connecting member 200, the ratchet teeth disengage from the ratchet groove, so that the movable plate 522 is pushed up in the direction away from the gear 526 and compresses the third elastic member 527.

[0098] Specifically, in order to allow the damping mechanism 500 to return to its original position smoothly when the rear headrest is extended, the gear 526 and the movable plate 522 can be set to a one-way meshing transmission mode. Specifically, the gear teeth of the gear 526 are set as a ratchet, and the top surface of the ratchet teeth of the ratchet wheel is an inclined surface, and the side surface is a vertical surface. Accordingly, a corresponding ratchet tooth can be set on the end surface of the movable plate 522 facing the ratchet wheel. The shape and size of the ratchet tooth are the same as those of the gear 526, and the inclined surface is set in the opposite direction to make the drive directional. In this embodiment, the inclined surface of the ratchet teeth on the movable rod 512 can be set on the side facing the first push rod 510, while the inclined surface of the ratchet teeth of the ratchet wheel faces the side away from the second push rod 520. In this way, when the second push rod 520 pushes the movable plate 522 to move in the direction of the baffle, the ratchet teeth on the movable plate 522 and the ratchet wheel come into contact, and the vertical direction of the two ratchet teeth is reversed. The surfaces are in contact, and the force applied by the second push rod 520 to the movable plate 522 can be transmitted to the ratchet through the vertical surface, driving the fan blade 525 coaxially connected to the ratchet to rotate, thereby generating a damping force. When the second push rod 520 is separated from the movable plate 522, the second elastic member 523 pushes the movable plate 522 to move in the direction away from the baffle. At this time, the movable plate 522 and the ratchet teeth on the ratchet are in contact through the inclined surface, and the ratchet gives the movable plate 522 a force away from its direction, thereby realizing the separation of the ratchet and the movable plate 522. At this time, the movable plate 522 will not drive the ratchet to rotate, so no damping force will be generated during its return process, so that the movable plate 522 can smoothly return to its initial position. In addition, in order to ensure the stability of the movable plate 522 when it is unidirectionally engaged with the ratchet, the damping mechanism 500 can be provided with a third elastic member 527, and the third elastic member 527 can be provided on the side of the movable plate 522 away from the ratchet. The third elastic member 527 can be a rubber pad or a structure made of other elastic materials. One end of the third elastic member 527 can abut against the end surface of the movable plate 522 away from the ratchet, and the other end can abut against the second support member 521. The third elastic member 527 and the movable plate 522 can slide relative to each other. In this way, when the movable plate 522 is lifted by the ratchet, the movable plate 522 will compress the third elastic member 527 to store energy. When the movable plate 522 moves toward the baffle, the third elastic member 527 can apply elastic force to the movable plate 522, causing the movable plate 522 to abut against the ratchet, thereby ensuring the stability of the connection between the two.

[0099] Furthermore, the damping mechanism 500 also includes a slider 528, a limiting groove is provided on the second support member 521, the limiting groove and the sliding groove are arranged opposite to each other, the slider 528 is slidably arranged in the limiting groove, and a rolling member is rotatably provided between the slider 528 and the limiting groove, and the third elastic member 527 connects the slider 528 and the movable plate 522.

[0100] In this embodiment, the damping mechanism 500 can be provided with a slider 528. Specifically, a limiting groove can be provided on the second support member 521. The limiting groove can be parallel to the slide groove and spaced apart. The slider 528 is slidably arranged in the limiting groove. The third elastic member 527 can be a compression spring. The compression spring connects the slider 528 and the opposite end faces on the movable plate 522. In this way, the compression spring contacts the slider 528 and the movable plate 522 in the limiting groove and the slide groove respectively. The slider 528 and the third elastic member 527 can ensure that the movable plate 522 is tightly connected to the ratchet. When the movable plate 522 moves, the slider 528 can also be driven to move synchronously through the third elastic member 527. In addition, in order to reduce the friction between the two during reciprocating motion, a rolling element can be provided on the end face of the slider 528 connected to the limiting groove. The rolling element can be a ball embedded in the slider 528. In this way, the sliding friction between the slider 528 and the limiting groove is replaced by rolling friction through the setting of the rolling element, thereby reducing the friction during the movement of the slider 528, thereby ensuring the smooth movement of the movable plate 522.

[0101] Furthermore, gear teeth are provided on the circumference of the gear 526, and a tooth groove meshing with the gear teeth is provided on the side of the movable plate 522 facing the gear 526. A driven ratchet is provided on the end surface of the gear 526 facing the damping cylinder 524. The driven ratchet is arranged along the circumference of the end surface. The damping mechanism 500 further includes:

[0102] A rotating shaft connecting the fan blade 525 and the gear 526;

[0103] The transmission wheel 529 is slidably mounted on the outer circumference of the rotating shaft and is in transmission connection with the rotating shaft. The end surface of the transmission wheel 529 facing the gear 526 is provided with an active ratchet, and the active ratchet and the driven ratchet form a one-way meshing structure that can be disengaged; and

[0104] The fourth elastic member 530 connects the damping cylinder 524 and the transmission wheel 529 to move the transmission wheel 529 toward the gear 526 .

[0105] This embodiment provides a second implementation method of the one-way meshing transmission between the gear 526 and the movable plate 522 .

[0106] In this embodiment, the circumferential surface of the gear 526 can be provided with gear teeth, and the gear teeth can be conventional tooth types such as straight teeth or helical teeth. Correspondingly, the end surface corresponding to the gear 526 on the movable plate 522 can be provided with gear teeth or tooth grooves that match the gear 526. The gear teeth are engaged with the movable plate 522 for transmission. In addition, a ratchet is provided on the end surface of the gear 526 facing the damping cylinder 524. The ratchet is arranged along the circumferential direction of the gear 526, and the top surface of the ratchet is designed to be a slope. In addition, a rotating shaft is also rotatably connected to the damping cylinder 524. The rotating shaft is passed through the damping cylinder 524, and the fan blades 525 in the damping cylinder 524 are arranged on the damping cylinder 524. On the peripheral wall of the rotating shaft, the other end of the rotating shaft is rotatably connected to the gear 526, so that the gear 526 can rotate around the rotating shaft; a transmission wheel 529 is also sleeved on the rotating shaft, and the transmission wheel 529 can be a circular ring structure. The transmission wheel 529 is arranged between the damping cylinder 524 and the gear 526, wherein the transmission wheel 529 is provided with a ratchet on the end face facing the gear 526, and the ratchet has the same shape and size as the ratchet on the gear 526. In this way, the transmission wheel 529 and the gear 526 form a one-way meshing structure through the ratchet; in order to reduce the stress at the meshing part, a plurality of ratchets can be provided, and the force can be dispersed by the meshing of multiple ratchets. In addition, in order to transmit the damping force in the damping cylinder 524 to the gear 526, the transmission wheel 529 is connected to the rotating shaft in a transmission manner. For example, a key is provided on the peripheral wall of the rotating shaft and a corresponding keyway is provided on the transmission wheel 529. The rotation of the transmission wheel 529 is driven by the cooperation of the key and the keyway, and the damping force is then transmitted to the gear 526 through the ratchet. When the lever 522 is disengaged from the movable plate 522, the movable plate 522 is driven by the second elastic member 523 to return to its original position. At this time, the movable plate 522 drives the gear 526 to rotate in the opposite direction. The inclined surface of the ratchet on the gear 526 abuts against the inclined surface of the ratchet on the transmission wheel 529, driving the transmission wheel 529 away from the gear 526 to achieve disengagement of the meshing. Therefore, no damping force will be generated during the return process of the movable plate 522, so that the movable plate 522 can smoothly return to its initial position. In addition, in order to ensure the stable engagement between the gear 526 and the transmission wheel 529, the damping mechanism 500 can also be provided with a fourth elastic member 530. The fourth elastic member 530 can be a telescopic spring, which can be arranged between the transmission member on the rotating shaft and the damping cylinder 524. One end of the telescopic spring abuts the damping cylinder 524, and the other end abuts the transmission wheel 529, pressing the transmission wheel 529 tightly against the gear 526. In this way, when the transmission wheel 529 is disengaged from the gear 526, the fourth elastic member 530 can push the transmission wheel 529 to abut against the gear 526, thereby ensuring that the two can engage smoothly when they need to engage, thereby ensuring the stability of the engagement.

[0107] Furthermore, the second elastic member 523 is a V-shaped spring embedded in the chute, connecting the end surface of the movable plate 522 and the side wall of the chute. To simplify the connection structure, in this embodiment, the second elastic member 523 can be a V-shaped spring, one end of which can be fixed to the baffle, and the other end can abut the end surface of the movable rod 512. In addition, the bent area of ​​the V-shaped spring can abut the side wall of the chute as a support point. In this way, when the movable plate 522 approaches the baffle, the end surface of the movable plate 522 abuts the V-shaped spring, compressing it and storing energy. When the movable plate 522 needs to return to its original position, the V-shaped spring will push the movable plate 522 to move. The V-shaped spring can be designed with a rectangular cross-section. Compared to using a conventional helical compression spring, the width of the damping mechanism 500 can be greatly reduced, facilitating a lightweight and thinner design.

[0108] Furthermore, the damping mechanism 500 includes:

[0109] a third ejector rod 531;

[0110] The third support member 532 is provided with a slide groove, and the slide groove is provided with an escape opening;

[0111] The movable plate 522 is provided on one side of the third push rod 531 and is slidably disposed in the slide groove;

[0112] a fifth elastic member 533 , disposed on a side of the movable plate 522 away from the third push rod 531 , and connecting the support member and the movable plate 522 ;

[0113] The damping cylinder 524 is provided on one side of the third support member 532. A cavity is formed in the damping cylinder 524, and a throttle hole is provided on the side wall of the cavity.

[0114] The second gear 534 is rotatably disposed in the cavity;

[0115] The rotating portion 535 is rotatably disposed within the cavity. The cross-sectional shape of the rotating portion 535 is a Lello triangle. The cross-sectional shape of the cavity matches the trajectory of the outer protruding portion of the rotating portion 535. The rotating portion 535 has a center hole at its center. The inner wall of the center hole is provided with an inner gear ring. The inner gear ring meshes with the second gear 534. The center of the rotating portion 535 is spaced apart from the center of the second gear 534.

[0116] The third gear 536 is located on opposite sides of the support member and the damping cylinder 524. The third gear 536 corresponds to the position of the avoidance opening and is coaxially connected to the second gear 534.

[0117] Among them, the rotating part 535 divides the cavity into three chambers. When the rotating part 535 rotates, the volumes of the three chambers increase or decrease in turn. In the connecting part 200 and the wearing frame 300, one is selected to set the second support member 521 and the damping cylinder 524, and the other is selected to set the third push rod 531.

[0118] This embodiment provides a third implementation of the damping mechanism 500 .

[0119] The third support member 532 can be a bracket for supporting other functional components, and the third push rod 531 and the third support member 532 can be respectively arranged on the connecting member 200 and the wearing frame 300, and the positions of the two can be interchangeable; a sliding groove is provided on the third support member 532, and the sliding groove extends in the direction of the third push rod 531, and a movable plate 522 is slidably connected to the sliding groove, and the movable plate 522 can move along the sliding groove toward or away from the third push rod 531; a fifth elastic member 533 is connected to the side of the movable plate 522 away from the third push rod 531, and the fifth elastic member 533 connects the movable plate 522 and the third support member 532. In this embodiment, the fifth elastic member 533 can be a telescopic spring, etc., and the third support member 532 A baffle is provided at one end away from the third push rod 531, and one end of the fifth elastic member 533 abuts against the baffle and the other end abuts against the movable plate 522. When the movable plate 522 slides toward the baffle, the fifth elastic member 533 will be compressed and apply elastic force to the movable plate 522 to prevent it from continuing to move; the damping mechanism 500 also includes a damping cylinder 524, which has a cavity inside, and a rotating part 535 is provided in the cavity, wherein the rotating part 535 can be a rotor with a cross-section of a Lello triangle, similar to the structure in a rotary engine. The rotating part 535 rotates eccentrically in the cavity, and the internal shape of the cavity is the same as the movement trajectory of the vertex of the rotating part 535 when it rotates. In this way, when the rotating part 535 rotates, the three vertices of the rotating part 535 all contact the inner wall of the cavity, thereby dividing the cavity into three independent air chambers. As the rotating part 535 rotates, the space of the three air chambers will periodically increase and decrease. In addition, a throttle hole is provided on the side wall of the damping cylinder 524, and the throttle hole is connected to the inner wall of the cavity. In this way, when the rotating part 535 rotates, the air chamber space connected to the throttle hole will change periodically, and the air pressure inside it will also increase or decrease regularly, thereby generating a damping force on the rotating part 535; in order to ensure the continuous action of the damping force when the rotating part 535 rotates, two throttle holes can be provided on the outside of the damping cylinder 524, wherein the throttle holes are evenly spaced along the side wall of the damping cylinder 524, when the air chamber where the throttle hole on one side is located is compressed to the minimum space, as the rotating part 535 continues to rotate, the air chamber where the throttle hole on the other side is located will be compressed, and the continuity of the damping force is ensured by the cyclic compression of the air chambers where the two throttle holes are located.In order to transmit the damping force to the movable plate 522, the damping cylinder 524 is also rotatably connected to a second gear 534, wherein the second gear 534 is coaxial with the rotation center of the rotating portion 535. Accordingly, a center hole can be opened at the center position of the rotating portion 535. The size of the center hole is larger than that of the second gear 534. An inner gear ring is fixed on the inner wall of the center hole, and the second gear 534 is meshed with the inner gear ring for transmission. In addition, a third gear 536 is also rotatably connected to the outer wall of the damping cylinder 524. The third gear 536 and the second gear 534 can be coaxially connected. Accordingly, on the movable plate 52 The end surface facing the third gear 536 may be provided with a protruding tooth or a tooth groove, and the movable plate 522 is meshed with the third gear 536 through the protruding tooth or the tooth groove for transmission. In order to facilitate the connection between the movable plate 522 and the third gear 536, a clearance opening may be provided on the sliding groove of the third support member 532. The clearance opening may correspond to the position of the third gear 536. In this way, the gear teeth of the third gear 536 can extend into the clearance opening and mesh with the movable plate 522. When the movable plate 522 slides along the sliding groove, it drives the third gear 536 to rotate, thereby driving the second gear 534 coaxially connected thereto to rotate. Since the second gear 534 The second gear 534 is meshed with the inner gear ring of the rotating part 535, and the second gear 534 will drive the rotating part 535 to rotate, thereby generating a damping force. In actual application, when the wearing frame 300 is stretched outward, the wearing frame 300 is away from the connecting member 200, and the third push rod 531 moves away from the movable plate 522. When the wearing frame 300 returns to its original position, the third push rod 531 will abut against the movable plate 522, pushing the movable plate 522 toward the baffle on the opposite side. At this time, the fifth elastic member 533 will be compressed and transmit the elastic force to the movable plate 522 to prevent it from moving. In addition, since the movable plate 522 drives the inner of the damping cylinder 524 When the rotating portion 535 rotates, the damping force exerted on the rotating portion 535 will be transmitted to the movable plate 522. In this way, the damping force and the elastic force of the fifth elastic member 533 will offset the force transmitted to the movable rod 512 by the elastic adjustment mechanism 400, thereby slowing down the speed of the movable plate 522 and thus reducing the return speed of the wearing frame 300. As the wearing frame 300 gradually returns to its original position, the force exerted on the movable plate 522 by the elastic adjustment mechanism 400 will gradually decrease, while the elastic force of the fifth elastic member 533 will gradually increase. When the two opposing forces reach equilibrium, the wearing frame 300 will eventually stop moving. It is conceivable that when the third push rod 531 is about to disengage from the movable plate 522, the fifth elastic member 533 tends to recover its deformation, pushing the movable plate 522 to move away from the baffle, and finally returning to its original state. The provision of the fifth elastic member 533 can also achieve the reset function of the damping mechanism 500.

[0120] Furthermore, a vent hole is provided on the bottom wall of the cavity, and the vent hole is covered with a one-way baffle 537 to prevent the air in the cavity from overflowing from the vent hole.

[0121] In order to achieve the one-way damping effect of the damping mechanism 500, a vent hole can be opened on the inner wall of the cavity of the damping cylinder 524, and a one-way baffle 537 can be set on the vent hole to achieve the one-way ventilation effect of the vent hole. In this embodiment, the vent hole can be opened on the side wall of the cavity facing the end face of the rotating part 535, and the vent hole is arranged near the throttle hole. The one-way baffle 537 can be a flexible metal sheet, and the connection is achieved by spot welding one side of the one-way baffle 537 to the damping cylinder 524. By adjusting the size of the third gear 536 and the transmission ratio of the second gear 534 and the inner gear ring of the rotating part 535, the movable plate 522 is moved from a distance to a distance close to the baffle. During the rotation of the rotating part 535, the vent hole and the throttle hole are always in the same air chamber, that is, the rotating part 535 swings within a limited angle. When the movable plate 522 moves toward the baffle, it drives the rotating part 535 to rotate, and the volume of the air chamber where the throttle hole is located decreases. At this time, a damping force is generated. When the movable plate 522 moves toward the direction away from the baffle, the volume of the air chamber where the throttle hole is located increases and the air pressure decreases. At this time, the external air pressure pushes open the one-way baffle 537, and the gas can quickly enter the air chamber, so that no damping force is generated, thereby ensuring the smooth return of the movable plate 522.

[0122] Furthermore, any one of the magnet and the magnetic induction switch is provided on the first support member 511 , the second support member 521 , or the third support member 532 , and the other one of the magnet and the magnetic induction switch is provided on the movable rod 512 or the movable plate 522 . In the above embodiment, since there are relatively moving parts in the damping mechanism 500, and the relative movement is strongly related to the relative position of the wearing frame 300 and the connecting member 200, it is possible to set a sensing element on the relatively moving part and sense the position of the wearing frame 300 and the connecting member 200 by detecting the relative movement; for example, a magnet or a magnetic induction switch is set on the first support member 511, the second support member 521 or the third support member 532, and correspondingly, another of the magnets or magnetic induction switches is set on the movable rod 512 or the movable plate 522. When the relative position of the wearing frame 300 and the connecting member 200 changes, the position of the magnet and the magnetic induction switch will also change, that is, the magnet can move closer to or away from the magnetic induction switch, thereby switching the on / off state of the magnetic induction switch, and confirming whether the wearing frame 300 has returned to its original position by detecting the state of the magnetic induction switch. In addition, it is conceivable that the magnetic induction switch is electrically connected to the display component 100 of the head-mounted display device, and the switch of the display component 100 is controlled by its on / off control, which is also conducive to improving the user experience.
