Abstract
Description
Technical Field
[0001] This application relates to the field of eyeglasses technology, and more specifically, to an interpupillary distance adjustment structure and a smart wearable device. Background Technology
[0002] The display principle of smart wearable devices such as VR glasses is that the left and right eye screens display images for the left and right eyes respectively. After the human eye receives this information with differences, it generates a sense of stereoscopic effect in the brain. VR glasses generally split the content into two halves and use lenses to achieve superimposed imaging. This often causes the center of the human pupil, the center of the lens, and the center of the screen (after splitting) to be out of alignment, resulting in poor visual effects and a host of problems such as blurriness and distortion.
[0003] Ideally, the center of the human pupil, the center of the lens, and the center of the screen (after splitting the screen) should be on a straight line. In this case, it is necessary to adjust the "interpupillary distance" of the lens to make it coincide with the human pupillary distance to obtain the best visual effect.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0044] This application provides an embodiment of an interpupillary distance adjustment structure, referring to... Figures 1-5 The interpupillary distance adjustment structure includes: a support housing 1, a first optical module 21, a second optical module 22, and a guide 3.
[0045] The supporting housing 1 is provided with positioning ribs 12. The first optical module 21 is provided with a first positioning post 210, and the second optical module 22 is provided with a second positioning post 220. The guide member 3 includes a first connecting rod 31, a second connecting rod 32, and a third connecting rod 33, all of which are connected to each other in pairs. The first connecting rod 31 has an inclined first guide groove 311, and the first positioning post 210 is slidably disposed within the first guide groove 311. The second connecting rod 32 has an inclined second guide groove 321, and the second positioning post 220 is slidably disposed within the second guide groove 321. The third connecting rod 33 has a third guide groove 331, which is slidably sleeved around the positioning ribs 12.
[0046] When the guide 3 slides vertically relative to the support housing 1, the first optical module 21 and the second optical module 22 can move horizontally.
[0047] In this embodiment, the interpupillary distance adjustment structure mainly includes a supporting housing 1, a first optical module 21, a second optical module 22, and a guide member 3. The supporting housing 1 may have a head-mounted mechanism, or it may be connected to other head-mounted components to achieve head-mountability. The first optical module 21 and the second optical module 22 are arranged horizontally on the supporting housing 1 and are movably mounted on it. The first optical module 21 and the second optical module 22 are arranged horizontally; either the first optical module 21 or the second optical module 22 can be on the left side. Horizontal movement refers to movement from left to right or from right to left. Under the action of the guide member 3, the first optical module 21 and the second optical module 22 can move horizontally on the supporting housing 1. The first optical module 21 and the second optical module 22 move simultaneously to adjust the interpupillary distance between them.
[0048] Specifically, a positioning rib 12 is provided on the support housing 1, a first positioning post 210 is provided on the first optical module 21, and a second positioning post 220 is provided on the second optical module 22. The guide member 3 cooperates with the positioning rib 12, the first positioning post 210, and the second positioning post 220 to enable the guide member 3 to drive the first optical module 21 and the second optical module 22 to move horizontally when moving vertically.
[0049] The guide member 3 cooperates with the positioning rib 12, which guides the guide member 3. For example, the guide member 3 includes a third connecting rod 33 with a third guide groove 331. The third guide groove 331 is fitted outside the positioning rib 12. When the guide member 3 slides vertically relative to the support housing 1 (moving from top to bottom or from bottom to top), the third guide groove 331 can slide along the positioning rib 12, limiting the sliding direction of the guide member 3. For example, with the third guide groove 331 of the third connecting rod 33 fitted outside the positioning rib 12, when the guide member 3 slides relative to the support housing 1, the guide member 3 can slide along the surface of the positioning rib 12, preventing the guide member 3 from deviating from the vertical direction and preventing the guide member 3 from detaching from the positioning rib 12 (for example, if the third connecting rod 33 does not slide on the same plane as the first connecting rod 31 and the second connecting rod 32, the guide member 3 may detach from the positioning rib 12). This also prevents the guide member 3 from detaching from the first positioning post 210 and the second positioning post 220.
[0050] The guide member 3 cooperates with the first positioning post 210 and the second positioning post 220, so that when the guide member 3 moves in the vertical direction, it can drive the first optical module 21 and the second optical module 22 to move in the horizontal direction.
[0051] Specifically, the guide member 3 includes a first connecting rod 31, a second connecting rod 32, and a third connecting rod 33. The first connecting rod 31, the second connecting rod 32, and the third connecting rod 33 are connected to each other in pairs. Thus, when the third connecting rod 33 moves vertically, the first connecting rod 31 and the second connecting rod 32 also move vertically along with it. For example, the first connecting rod 31 and the second connecting rod 32 can be connected together, or the first connecting rod 31 and the third connecting rod 33 can be connected together. In a specific example, the guide member 3 is a one-piece molded structure.
[0052] Specifically, the first connecting rod 31 has an inclined first guide groove 311, and the first positioning post 210 is slidably disposed in the first guide groove 311. The second connecting rod 32 has an inclined second guide groove 321, and the second positioning post 220 is slidably disposed in the second guide groove 321. When the guide member 3 slides in the vertical direction, the first positioning post 210 does not move in conjunction with the first connecting rod 31 (when the first positioning post 210 moves in conjunction with the first connecting rod 31, the first positioning post 210 moves in the vertical direction with the guide member 3). Instead, the first positioning post 210 can be in the first guide groove 311, and with the help of the inclined first guide groove 311, the first optical module 21 can move in the horizontal direction. Furthermore, when the guide member 3 slides in the vertical direction, the second positioning post 220 does not move in conjunction with the second connecting rod 32 (when the second positioning post 220 moves in conjunction with the second connecting rod 32, the second positioning post 220 moves in the vertical direction along with the guide member 3). Instead, the second positioning post 220 can be in the second guide groove 321, and the second optical module 22 can move in the horizontal direction by means of the inclined second guide groove 321.
[0053] For example, the first guide groove 311 is inclined, and the first positioning post 210 is slidably disposed in the first guide groove 311. When the guide member 3 slides along the vertical direction, the force in the vertical direction can be decomposed into a force in the vertical direction and a force in the horizontal direction due to the inclined arrangement of the first guide groove 311. Under the force in the horizontal direction, the first positioning post 210 can move along the horizontal direction, that is, the first optical module 21 can move along the horizontal direction.
[0054] For example, the second guide groove 321 is inclined, and the second positioning post 220 is slidably disposed in the second guide groove 321. When the guide member 3 slides in the vertical direction, the force in the vertical direction can be decomposed into a force in the vertical direction and a force in the horizontal direction due to the inclined arrangement of the second guide groove 321. Under the force in the horizontal direction, the second positioning post 220 can move in the horizontal direction, that is, the second optical module 22 can move in the horizontal direction.
[0055] It should be noted that the second guide groove 321 is inclined, and the first guide groove 311 is inclined. When the inclination direction of the first guide groove 311 is the same as that of the second guide groove 321, when the guide member 3 moves vertically, the first optical module 21 and the second optical module 22 move to the left or to the right at the same time. When the forces on the first optical module 21 and the second optical module 22 are equal, the setting position of the first optical module 21 and the second optical module 22 is adjusted. When the forces on the first optical module 21 and the second optical module 22 are unequal, the interpupillary distance between the first optical module 21 and the second optical module 22 can be adjusted at the same time as the first optical module 21 and the second optical module 22 are adjusted.
[0056] The second guide groove 321 is inclined, and the first guide groove 311 is inclined. When the inclination direction of the first guide groove 311 is not the same as that of the second guide groove 321, when the guide member 3 moves in the vertical direction, the first optical module 21 and the second optical module 22 move relatively closer or further away.
[0057] Therefore, in this embodiment, the guide member 3 drives the first optical module 21 and the second optical module 22 to move horizontally, adjusting their positions on the support housing 1 so that their interpupillary distance coincides with that of the human eye, achieving optimal visual effect. Furthermore, this application improves upon the first optical module 21, the second optical module 22, and the support housing 1. The introduction of the guide member 3 allows for adjustment of the interpupillary distance between the first optical module 21 and the second optical module 22. The interpupillary distance adjustment scheme implemented in this embodiment is simple and easy to operate.
[0058] Optionally, the first positioning post 210 is fixed to the back of the first optical module 21. For example, the first optical module 21 has a back cover, and the first positioning post 210 is disposed on the back cover. In one example, the first positioning post 210 can be glued or welded to the back cover, or the first positioning post 210 and the back cover can be an integral structure. The second positioning post 220 is fixed to the back of the second optical module 22. For example, the second optical module 22 has a back cover, and the second positioning post 220 is disposed on the back cover.
[0059] In one embodiment, refer to Figures 2-3 The third guide groove 331 has a first end and a second end, with the first end located above the second end.
[0060] When the inclination directions of the first guide groove 311 and the second guide groove 321 are opposite, and when the first end of the third guide groove 331 abuts against the positioning rib 12, the interpupillary distance between the first optical module 21 and the second optical module 22 is the longest.
[0061] When the inclination directions of the first guide groove 311 and the second guide groove 321 are opposite, and the second end of the third guide groove 331 abuts against the positioning rib 12, the interpupillary distance between the first optical module 21 and the second optical module 22 is the shortest.
[0062] In this embodiment, the inclination directions of the first guide groove 311 and the second guide groove 321 are opposite, for example, referring to... Figures 1-3 The first guide groove 311 is inclined away from the second optical module 22, and the second guide groove 321 is inclined away from the first optical module 21. Thus, when the guide member 3 moves vertically, the first optical module 21 and the second optical module 22 move simultaneously closer to or further away from each other. When the guide member 3 is pulled downwards, causing the first end of the third guide groove 331 to abut against the positioning rib 12, the first optical module 21 moves to the left and reaches its leftmost position, while the second optical module 22 moves to the right and reaches its rightmost position, resulting in the maximum interpupillary distance between the first and second optical modules 21. When the guide member 3 is pushed upwards, causing the second end of the third guide groove 331 to abut against the positioning rib 12, the first optical module 21 moves to the right and reaches the middle region of the supporting housing 1, while the second optical module 22 moves to the left and reaches the middle region of the supporting housing 1, resulting in the shortest interpupillary distance between the first and second optical modules 21.
[0063] In one embodiment, the guide 3 is either "Y" shaped or "individual".
[0064] In this embodiment, the structure of the guide member 3 is defined, and the guide member 3 can be Y-shaped or "U"-shaped. The Y-shaped or "U"-shaped connecting rod extending vertically is the third connecting rod 33, and the two connecting rods are either the first connecting rod 31 or the second connecting rod 32, for example, referring to... Figures 2-3 The connecting rod located to the left of the third connecting rod 33 is the first connecting rod 31, and the connecting rod located to the right of the third connecting rod 33 is the second connecting rod 32.
[0065] The first connecting rod 31 and the second connecting rod 32 are both inclined, while the third connecting rod 33 is vertically oriented. The first connecting rod 31 has a first guide groove 311, specifically, an inclined first guide groove 311 is formed on the first connecting rod 31 along its orientation. The second connecting rod 32 has a second guide groove 321, specifically, an inclined second guide groove 321 is formed on the second connecting rod 32 along its orientation. The first guide groove 311 is fitted over the first positioning post 210, and the second guide groove 321 is fitted over the second positioning post 220. When the third connecting rod 33 is pulled or pushed vertically, the first positioning post 210 can slide within the first guide groove 311, and the second positioning post 220 can slide within the second guide groove 321, thereby enabling the first optical module 21 and the second optical module 22 to move horizontally.
[0066] Therefore, in this embodiment, the structure of the guide 3 is limited, making the adjustment of the interpupillary distance between the first optical module 21 and the second optical module 22 simple and easy for the user to operate.
[0067] Optionally, the inner walls of the first guide groove 311 and the second guide groove 321 can be smooth surfaces, or the inner walls of the first guide groove 311 and the second guide groove 321 can be composed of multiple arc-shaped surfaces.
[0068] In one embodiment, refer to Figures 2-3 The positioning rib 12 is located between the first optical module 21 and the second optical module 22; the first positioning post 210 is located in the first region of the first optical module 21, and the second positioning post 220 is located in the second region of the second optical module 22. The first region and the second region are adjacent in the horizontal direction.
[0069] In this embodiment, the position of the first positioning post 210 in the first optical module 21 and the position of the second positioning post 220 in the second optical module 22 are defined, so that the guide 3 can drive the first optical module 21 and the second optical module 22.
[0070] For example, if the first positioning post 210 is located in the first region of the first optical module 21 and the second positioning post 220 is located in the second region of the second optical module 22, then by applying a small force to the guide member 3 in the vertical direction, the first optical module 21 and the second optical module 22 can be adjusted to the ideal interpupillary distance.
[0071] For example, the guide 3 has a symmetrical structure, with the first positioning post 210 located in the first region of the first optical module 21 and the second positioning post 220 located in the second region of the second optical module 22. In this way, when a small force is applied to the guide 3 in the vertical direction, the first optical module 21 and the second optical module 22 can be adjusted to the ideal interpupillary distance.
[0072] In one embodiment, the first optical module 21 has a first edge 211, and the center of the first positioning post 210 is spaced apart from the first edge 211 by a first distance;
[0073] The second optical module 22 has a second edge 221, the first edge 211 and the second edge 221 are adjacent in the horizontal direction, and the center of the second positioning post 220 is spaced a second distance from the second edge 221;
[0074] The first distance is equal to the second distance.
[0075] In this embodiment, the positions of the first positioning post 210 and the second positioning post 220 are defined. The first positioning post 210 and the second positioning post 220 are symmetrically arranged, and the positioning rib 12 is located between the first optical module 21 and the second optical module 22. That is, the first positioning post 210 and the second positioning post 220 are symmetrical about the positioning rib 12.
[0076] In this embodiment, the relative positions of the first positioning post 210, the second positioning post 220 and the positioning rib 12 are defined. When the guide 3 is pushed or pulled in the vertical direction, the first optical module 21 and the second optical module 22 can be subjected to equal forces, which facilitates the adjustment of the interpupillary distance between the first optical module 21 and the second optical module 22.
[0077] In one embodiment, the supporting housing 1 includes a housing body and a supporting column 11. The housing body has a nose bridge frame 10, and the supporting column 11 is fixed to the rear surface of the nose bridge frame 10. In one embodiment, the supporting column 11 has a positioning rib 12 on its surface opposite to the housing body.
[0078] In this embodiment, the structure of the supporting shell 1 is defined, wherein the supporting shell 1 includes a shell body and a supporting column 11, and a positioning rib 12 is provided on the supporting column 11. In a specific embodiment, the shell body, the supporting column 11 and the positioning rib 12 are integrally formed.
[0079] For example, the first positioning post 210 of the first optical module 21 is assembled into the first guide groove 311, the second positioning post 220 of the second optical module 22 is assembled into the second guide groove 321, the positioning rib 12 of the supporting housing 1 is assembled into the third guide groove 331, and the guide member 3 is supported on the support post 11 of the supporting housing 1. The support post 11 provides support and load-bearing for the guide member 3. In this way, without adjusting the interpupillary distance between the first optical module 21 and the second optical module 22, the support post 11 can provide support for the guide member 3.
[0080] In one embodiment, refer to Figure 1 , Figure 4 and Figure 5 The interpupillary distance adjustment structure also includes a cover plate 4, which covers the supporting housing 1 to form a receiving space. The third connecting rod 33 of the guide member 3 extends out of the receiving space.
[0081] In this embodiment, the interpupillary distance adjustment structure further includes a cover plate 4, which covers the support housing 1, thus enclosing and forming an accommodating space. The first optical module 21 and the second optical module 22 are located within this accommodating space. For example, the cover plate 4 can be glued and fixed to the support housing 1, or the cover plate 4 can be fixed to the support housing 1 by fasteners or the like.
[0082] When the cover plate 4 is fixed on the support housing 1, the third connecting rod 33 of the guide member 3 extends out of the receiving space. Thus, from the appearance of the interpupillary distance adjustment structure, part of the third connecting rod 33 is exposed, which makes it convenient for the user to operate the third connecting rod 33 and realize the vertical movement of the guide member 3.
[0083] In an optional embodiment, a first mating portion is formed on the surface of the cover plate 4 near the supporting housing 1, and a second mating portion is provided on the first optical module 21 and the second optical module 22. The first and second mating portions are slidably engaged. This allows the first and second optical modules 21 and 22 to slide on the cover plate 4 when sliding horizontally, preventing them from making hard contact with the cover plate 4 and affecting their horizontal movement.
[0084] For example, the first mating part can be a shaft, and the second mating part can be a hole structure. Alternatively, the first mating part can be a slide, and the second mating part can be a protrusion structure that mates with the slide.
[0085] In one embodiment, refer to Figure 1 , Figure 4 and Figure 5The guide member 3 is provided with a limiting post 34, and the cover plate 4 is provided with a limiting groove 41. The limiting post 34 is located in the limiting groove 41. When the guide member 3 slides relative to the supporting housing 1, the limiting post 34 slides relative to the limiting groove 41.
[0086] In this embodiment, when the cover plate 4 is fixed to the support housing 1 and the limiting post 34 is assembled in the limiting groove 41, the limiting post 34 can move within the limiting groove 41 when the guide member 3 moves vertically. This avoids friction between the guide member 3 and the cover plate 4, preventing the guide member 3 from moving unevenly. For example, refer to... Figure 3 The limiting post 34 is located in the connection area of the first connecting rod 31, the second connecting rod 32 and the third connecting rod 33.
[0087] In one embodiment, refer to Figure 4 The cover plate 4 forms a receiving groove 42, and the third connecting rod 33 is located in the receiving groove 42 and extends out of the receiving space.
[0088] For example, a receiving groove 42 is formed on the surface of the cover plate 4 near the supporting housing 1. The width of the receiving groove 42 is the same as the width of the third connecting rod 33, or it can be slightly larger than the width of the third connecting rod 33. For example, a first rib and a second rib are provided on the surface of the cover plate 4 near the supporting housing 1. The first rib and the second rib are spaced apart in the horizontal direction to form the receiving groove 42 on the surface of the cover plate 4 near the supporting housing 1.
[0089] With the cover plate 4 fixed on the support housing 1, the third connecting rod 33 is located in the receiving groove 42 and extends out of the receiving groove 42. In this way, when the guide 3 moves in the vertical direction, the receiving groove 42 can also limit the third connecting rod 33.
