Description

Technical Field

[0001] This application relates to the field of eyewear technology, and in particular to an interpupillary distance adjustment mechanism and smart glasses. Background Technology

[0002] Like smartphones, smart glasses have their own operating system. Users can install software and other programs provided by software service providers. They can perform functions such as adding schedules, map navigation, interacting with friends, taking photos and videos, and making video calls through voice or gesture control. They can also access wireless networks through mobile communication networks.

[0003] Smart glasses use two display components to show images with parallax, simulating the principle of parallax in the human eye to enable users to perceive stereoscopic graphics. The interpupillary distance between the two display components must correspond to the user's interpupillary distance for optimal user experience.

[0004] In related technologies, the display components are slidably mounted on the housing, and each display component has a rack. The housing has a gear that meshes with the rack, and the interpupillary distance between the two display components is adjusted by rotating the gear. This adjustment structure occupies a large space and has poor reliability in maintaining the interpupillary distance, easily causing changes in the interpupillary distance between the two display components when the smart glasses are shaken. Utility Model Content

[0005] The embodiments of this application aim to provide an interpupillary distance adjustment mechanism and smart glasses, so as to at least reduce the space occupied by the interpupillary distance adjustment mechanism and improve the reliability of interpupillary distance maintenance.

[0006] In order to solve the above-mentioned technical problems, the embodiments of this application adopt the following technical solutions: In a first aspect, embodiments of this application provide an interpupillary distance adjustment mechanism, comprising a mounting base, a sliding base, and a pressing member; the sliding base is slidably disposed on the mounting base along a first direction, the sliding base including a first surface opposite to the mounting base, the sliding base having a plurality of grooves on the first surface, the plurality of grooves being arranged along the first direction; the pressing member is disposed on the mounting base; when the sliding base slides relative to the mounting base, the pressing member slides along the inner wall of the first surface or the groove; when the sliding base slides relative to the mounting base to a preset position, the pressing member abuts against the inner wall of the groove. This improves the problem of interpupillary distance changes between the two display components when smart glasses are shaken, enhancing the reliability of interpupillary distance maintenance; furthermore, the interpupillary distance adjustment mechanism of this application embodiment does not require complex gears and racks, has a simple structure, and reduces the space occupied by the interpupillary distance adjustment mechanism.

[0007] In some embodiments, the mounting base has a mounting hole, the pressing member is disposed in the mounting hole, and one end of the pressing member extends out of the mounting hole. When assembling the interpupillary distance adjustment mechanism, the pressing member is first placed in the mounting hole, and then the sliding seat is slidably installed on the mounting base. There is no need for a complex connection between the pressing member and the mounting base, which simplifies the structure and assembly complexity of the interpupillary distance adjustment mechanism.

[0008] In some embodiments, one end of the pressing member is provided with a spherical surface, and the pressing member abuts against the inner wall of the groove through the spherical surface. By abutting against the inner wall of the groove with the spherical surface, the friction between the pressing member and the inner wall of the groove can be reduced, which improves the problem that when the pressing member is driven by external force to switch to the groove it is matched with, a large external force is required to squeeze the pressing member out of the groove, thus improving the user experience.

[0009] In some embodiments, the inner wall of the groove includes a second surface and a third surface. The end of the second surface facing away from the first direction is connected to the first surface, and the end of the second surface facing the first direction extends away from the mounting base. The end of the third surface facing away from the first direction is connected to the second surface, and the end of the second surface facing the first direction extends towards the mounting base to the first surface. The second surface and the third surface are mirror-symmetrical along the first direction. The second and third surfaces form a mirror-symmetrical "V" shape, so that when an external force drives the pressing member to switch to the corresponding groove in both directions, the required force is the same, improving the user experience.

[0010] In some embodiments, both the second and third surfaces are smoothly connected to the first surface. This allows the pressing member to slide smoothly from the second or third surface to the first surface, improving the problem of sudden changes in friction force on the pressing member caused by the angle at the connection and the problem of the pressing member being scratched at the angle.

[0011] In some embodiments, the second surface and the third surface are smoothly connected; and / or, when the sliding seat slides relative to the mounting seat to a preset position, the pressing member abuts against the second surface and the third surface, with the connection between the second surface and the third surface spaced apart from the pressing member. This improves the problem of sudden changes in frictional force on the pressing member and scratching of the pressing member at the corner due to the angle at the connection.

[0012] In some embodiments, the sliding seat has two connecting arms on the side facing the mounting base, and each connecting arm has a groove on the side facing the other connecting arm. The groove extends along the first direction, and the opposite ends of the mounting base are respectively disposed within the two grooves. This allows the sliding seat to be slidably mounted on the mounting base along the first direction, resulting in a simple structure and high reliability.

[0013] In some embodiments, the interpupillary distance adjustment mechanism further includes a mounting beam, and the mounting seat is disposed on the mounting beam; the mounting beam includes two fourth and fifth surfaces disposed opposite each other along the first direction, and at least a portion of at least one of the connecting arms is located between the fourth and fifth surfaces. This restricts the sliding seat relative to the mounting seat to a range along the first direction, improving the problem of the sliding seat slipping off the mounting groove and causing it to detach from the mounting seat, thus enhancing the reliability of the interpupillary distance adjustment mechanism.

[0014] In some embodiments, the pressing member is elastic; and / or, the side of the pressing member opposite to the sliding seat is provided with an elastic element, the elastic element applying an elastic force toward the sliding seat to the pressing member. This ensures that the pressing member always abuts against the sliding seat under the elastic force, improving the reliability of the pressing member in limiting the position of the sliding seat relative to the mounting base.

[0015] Secondly, embodiments of this application provide smart glasses, which include a display component and an interpupillary distance adjustment mechanism as described in any embodiment of the first aspect; the display component is disposed on the sliding base, and the display component is used to display images. The smart glasses employ the aforementioned interpupillary distance adjustment mechanism, which improves the problem of interpupillary distance changes between the two display components when the smart glasses are shaken; the interpupillary distance adjustment mechanism does not require complex gears and racks, has a simple structure, reduces the space occupied by the interpupillary distance adjustment mechanism, and thus reduces the size of the smart glasses.

[0025] The interpupillary distance (IPD) refers to the distance between the centers of the left and right pupils when the human eye is looking straight ahead; the interpupillary distance (IPD) refers to the distance between the optical centers of the two lenses in smart glasses, which needs to be matched with the user's interpupillary distance to ensure visual comfort and reduce dizziness. In the embodiments of this application, the IPD of the display component is the IPD.

[0026] In related technologies, the interpupillary distance between two display components is adjusted using a gear structure. For example, the display components are slidably mounted on a housing, each with a rack, and the housing has a gear that meshes with the rack. The interpupillary distance between the two display components is adjusted by rotating the gear. This adjustment structure occupies a large space and has poor reliability in maintaining the interpupillary distance, easily causing changes in the interpupillary distance between the two display components when the smart glasses are shaken.

[0027] In this embodiment, the position of the sliding seat relative to the mounting base is limited by the engagement of the pressing member and the groove of the sliding seat. Furthermore, when the sliding seat is driven to slide relative to the mounting base by an external force, the pressing member can switch its engaging groove, thereby adjusting the position of the sliding seat relative to the mounting base. When the pressing member switches its engaging groove by an external force, a certain magnitude of force is required, which is greater than the damping effect of the gear structure on the sliding seat. This improves the problem of interpupillary distance changes between the two display components when the smart glasses are shaken, thus enhancing the reliability of interpupillary distance maintenance. Moreover, the interpupillary distance adjustment mechanism of this embodiment does not require complex gears and racks, resulting in a simple structure and reduced space occupied by the interpupillary distance adjustment mechanism.

[0028] Firstly, please refer to Figures 1 to 3This application provides an interpupillary distance adjustment mechanism 100, which includes a mounting base 1, a sliding base 2, and a pressing member 3. The sliding base 2 is slidably disposed on the mounting base 1 along a first direction X. The sliding base 2 includes a first surface 21 disposed opposite to the mounting base 1. The sliding base 2 has a plurality of grooves 22 on the first surface 21, and the plurality of grooves 22 are arranged along the first direction X. The pressing member 3 is disposed on the mounting base 1. When the sliding base 2 slides relative to the mounting base 1, the pressing member 3 slides along the inner wall of the first surface 21 or the groove 22. When the sliding base 2 slides relative to the mounting base 1 to a preset position, the pressing member 3 abuts against the inner wall of the groove 22.

[0029] The mounting base 1 described above is used for mounting inside the smart glasses 200, for example, inside the housing of the smart glasses 200. Optionally, the mounting base 1 is in the shape of a rectangular plate.

[0030] The sliding base 2 is used to mount the display component 210. The display component 210 is used to display images. Thus, when the sliding base 2 slides relative to the mounting base 1, the display component 210 moves relative to the housing of the smart glasses 200, thereby adjusting the interpupillary distance between the two display components 210.

[0031] In some embodiments, the pressing member 3 is elastic. The pressing member 3 holds against the sliding seat 2 through its own elasticity. For example, the pressing member 3 is made of rubber, or partially of rubber; when the mounting base 1, the sliding seat 2, and the pressing member 3 are assembled, there is a pre-pressure between the pressing member 3 and the sliding seat 2, so that the pressing member 3 is compressed and holds against the sliding seat 2 under its own restoring deformation force. This ensures that the pressing member 3 always holds against the sliding seat 2 under the elastic force, improving the reliability of the pressing member 3 in limiting the position of the sliding seat 2 relative to the mounting base 1. Furthermore, the elasticity of the pressing member 3 reduces hard friction between the pressing member 3 and the sliding seat 2, reducing wear on both the pressing member 3 and the sliding seat 2.

[0032] In some embodiments, the side of the pressing member 3 facing away from the sliding seat 2 is provided with an elastic element (not shown), which applies an elastic force toward the sliding seat 2 to the pressing member 3. The pressing member 3 is held against the sliding seat 2 by the elastic force of the elastic element. Exemplarily, the elastic element is a straight spring or a spring sheet; when the mounting seat 1, the sliding seat 2 and the pressing member 3 are assembled, the elastic element is compressed between the pressing member 3 and the mounting seat 1, so that the pressing member 3 is held against the sliding seat 2 by the restoring deformation force of the straight spring. This ensures that the pressing member 3 is always held against the sliding seat 2 by the elastic force, improving the reliability of the pressing member 3 in limiting the position of the sliding seat 2 relative to the mounting seat 1. It is understood that when the pressing member 3 is provided with an elastic element on the side facing away from the sliding seat 2, the pressing member 3 can also be elastic, realizing a double elastic force driving the pressing member 3 to hold against the sliding seat 2.

[0033] In this embodiment, the pressing member 3 is always pressed against the sliding seat 2 under elastic force. When the pressing member 3 is pressed against the inner wall of the groove 22, and the sliding seat 2 is only subjected to the force of the pressing member 3, the pressing member 3 will gradually slide to the bottom of the groove 22, while the sliding seat 2 slides relative to the mounting seat 1. Finally, the sliding seat 2 comes to rest relative to the mounting seat 1, at which point the sliding seat 2 is in a preset position relative to the mounting seat 1. It can be understood that for each groove 22, the sliding seat 2 has one preset position relative to the mounting seat 1, therefore the sliding seat 2 has multiple preset positions relative to the mounting seat 1. When the sliding seat 2 is in a preset position relative to the mounting seat 1, the pressing member 3 cooperates with the groove 22 to prevent the sliding seat 2 from sliding relative to the mounting seat 1, that is, the position of the sliding seat 2 relative to the mounting seat 1 is limited by the cooperation between the pressing member 3 and the groove 22 of the sliding seat 2.

[0034] When the sliding seat 2 is driven to slide relative to the mounting seat 1 by an external force, the pressing member 3 can switch its mating groove 22, thereby adjusting the position of the sliding seat 2 relative to the mounting seat 1. It should be noted that when adjusting the position of the sliding seat 2 using the aforementioned gear structure, the gear structure typically has a certain amount of damping to prevent the sliding seat 2 from sliding freely relative to the mounting seat 1. This damping is usually achieved by a friction ring located at the shaft of the gear structure. The damping is usually small, and since a small knob needs to be manually turned to drive the gear structure, the damping is not set very high. When the pressing member 3 is driven to switch its mating groove 22 by an external force, a certain amount of force is required. This force needs to push the pressing member 3 out of the groove 22 through the inner wall of the groove 22. Therefore, this force is usually large and greater than the damping of the sliding seat 2 by the aforementioned gear structure. This improves the problem of interpupillary distance changes between the two display components 210 when the smart glasses 200 shakes, and improves the reliability of interpupillary distance maintenance. Furthermore, the interpupillary distance adjustment mechanism 100 of this embodiment does not require complex gears and racks, resulting in a simple structure and reducing the space occupied by the interpupillary distance adjustment mechanism 100. Moreover, the groove 22 cooperates with the pressing member 3 to achieve limiting, which is more reliable than using friction to create damping for limiting, further improving the problem of interpupillary distance changes between the two display components 210 when the smart glasses 200 shakes.

[0035] In some embodiments, please refer to Figure 2 and Figure 3 The mounting base 1 has a mounting hole 11, and the pressing member 3 is disposed in the mounting hole 11, with one end of the pressing member 3 extending out of the mounting hole 11. When assembling the pupil distance adjustment mechanism 100, the pressing member 3 is first placed in the mounting hole 11, and then the sliding base 2 is slidably installed on the mounting base 1. There is no need for a complicated connection between the pressing member 3 and the mounting base 1, which simplifies the structure and assembly complexity of the pupil distance adjustment mechanism 100.

[0036] In some embodiments, please refer to Figure 2and Figure 3 One end of the pressing member 3 is provided with a spherical surface 31, and the pressing member 3 abuts against the inner wall of the groove 22 through the spherical surface 31. By abutting against the inner wall of the groove 22 through the spherical surface 31, the friction between the pressing member 3 and the inner wall of the groove 22 can be reduced, which improves the problem that when the pressing member 3 is driven by external force to switch to the groove 22 it is matched with, a large external force is required to squeeze the pressing member 3 out of the groove 22, thus improving the user experience.

[0037] In some embodiments, please refer to Figure 3 The inner wall of the groove 22 includes a second surface 23 and a third surface 24. The end of the second surface 23 facing away from the first direction X is connected to the first surface 21, and the end of the second surface 23 facing the first direction X extends away from the mounting base 1. The end of the third surface 24 facing away from the first direction X is connected to the second surface 23, and the end of the second surface 23 facing the first direction X extends towards the mounting base 1 to the first surface 21. The second surface 23 and the third surface 24 are mirror-symmetrical along the first direction X. The second surface 23 and the third surface 24 are approximately "V"-shaped, and the second surface 23 and the third surface 24 are mirror-symmetrical along the first direction X. Therefore, when an external force drives the pressing member 3 to switch the groove 22 it is matched with in both directions, the magnitude of the required force is the same, improving the user experience.

[0038] In some embodiments, please refer to Figure 3 Both the second surface 23 and the third surface 24 are smoothly connected to the first surface 21. A smooth connection means the connection point is smooth and without any bends, allowing the pressing member 3 to slide smoothly from the second surface 23 or the third surface 24 to the first surface 21. This improves the problem of sudden changes in friction force on the pressing member 3 and scratching of the pressing member 3 at the bends caused by bends at the connection points. Optionally, the connection point between the second surface 23 and the first surface 21 has a rounded chamfer for a smooth connection. Optionally, the connection point between the third surface 24 and the first surface 21 also has a rounded chamfer for a smooth connection.

[0039] In some embodiments, the second surface 23 and the third surface 24 are smoothly connected. This allows the pressing member 3 to slide smoothly back and forth between the second surface 23 and the third surface 24, improving the problem of sudden changes in friction force on the pressing member 3 caused by the corner at the connection and the problem of scraping of the pressing member 3 at the corner. Optionally, the connection between the second surface 23 and the third surface 24 is provided with an arc-shaped chamfer for a smooth connection with the third surface 24, and / or, the connection between the third surface 24 and the second surface 23 is provided with an arc-shaped chamfer for a smooth connection with the second surface 23.

[0040] In some embodiments, please refer to Figure 3When the sliding seat 2 slides relative to the mounting seat 1 to the preset position, the pressing member 3 abuts against the second surface 23 and the third surface 24, with the connection between the second surface 23 and the third surface 24 spaced apart from the pressing member 3. Thus, the pressing member 3 does not contact the connection between the second surface 23 and the third surface 24, improving the problem of sudden changes in frictional force on the pressing member 3 caused by the angle at the connection between the second surface 23 and the third surface 24, and the problem of the angle scraping the pressing member 3 against the pressing member 3. Furthermore, when the sliding seat 2 slides relative to the mounting seat 1 to the preset position, the pressing member 3 needs to contact both the second surface 23 and the third surface 24 simultaneously, making the range of the preset position extremely small, approximately equal to a point position. Therefore, when the pressing member 3 and the groove 22 cooperate to limit the sliding seat 2 relative to the mounting seat 1 to the preset position, the sliding seat 2 is almost unable to wobble along the first direction X relative to the mounting seat 1, enhancing the limiting effect on the sliding seat 2.

[0041] In some embodiments, please refer to Figure 1 and Figure 2 The sliding seat 2 has two connecting arms 25 on the side facing the mounting seat 1, and a groove 251 on the side of the connecting arm 25 facing the other connecting arm 25. The groove 251 extends along the first direction X, and the opposite ends of the mounting seat 1 are respectively located in the two grooves 251. The groove 251 extends along the first direction X, and the mounting seat 1 can slide along the groove 251, thereby realizing that the sliding seat 2 can be slidably mounted on the mounting seat 1 along the first direction X. The sliding seat 2 can be slidably mounted on the mounting seat 1 along the first direction X by means of two connecting arms 25, which has a simple structure and high reliability. Optionally, the opposite ends of the mounting seat 1 are respectively adapted to the two grooves 251. For example, the mounting seat 1 is rectangular flat, and the groove 251 is cuboid. The thickness of the mounting seat 1 along the first direction X is equal to the width of the groove 251, and the distance between the bottoms of the two grooves 251 is equal to the width of the mounting seat 1 along the first direction X, so that the sliding seat 2 can only slide relative to the mounting seat 1 along the first direction X.

[0042] In some embodiments, please refer to Figure 4The interpupillary distance adjustment mechanism 100 further includes a mounting beam 4, with a mounting seat 1 disposed on the mounting beam 4. The mounting beam 4 includes two fourth surfaces 41 and fifth surfaces 42 arranged opposite each other along a first direction X, and at least a portion of at least one connecting arm 25 is located between the fourth surfaces 41 and fifth surfaces 42. Exemplarily, along the direction in which the mounting seat 1 and the sliding seat 2 are arranged, the connecting arm 25 has a limiting groove 43, which extends through opposite sides of the connecting arm 25 along this direction, such that the inner wall of the limiting groove 43 includes the fourth surfaces 41 and fifth surfaces 42 arranged opposite each other along the first direction X; the connecting arm 25 is at least partially located within the limiting groove 43, so that when viewed along the first direction X, the projection of the connecting arm 25 at least partially coincides with the projections of the fourth surfaces 41 and fifth surfaces 42. Thus, when the sliding seat 2 slides relative to the mounting seat 1 along the first direction X, there is at least one position where the connecting arm 25 abuts against the fourth surface 41, and at least one position where the connecting arm 25 abuts against the fifth surface 42. This restricts the sliding of the sliding seat 2 relative to the mounting seat 1 along the first direction X to a certain range, improving the problem of the sliding seat 2 detaching from the mounting seat 1 due to the mounting seat 1 slipping off the slide groove 251, and improving the reliability of the interpupillary distance adjustment mechanism 100. Optionally, the mounting seat 1 and the mounting beam 4 are detachably connected by screws. Optionally, one mounting beam 4 is equipped with two mounting seats 1.

[0043] Secondly, please refer to Figure 5 This application provides a smart glasses 200, which includes a display component 210 and an interpupillary distance adjustment mechanism 100. The display component 210 is disposed on a sliding base 2 and is used to display images. The smart glasses 200 employs the aforementioned interpupillary distance adjustment mechanism 100 to improve the problem of interpupillary distance changes between the two display components 210 when the smart glasses 200 is shaken, thus improving the reliability of interpupillary distance maintenance. The interpupillary distance adjustment mechanism 100 does not require complex gears and racks, has a simple structure, reduces the space occupied by the interpupillary distance adjustment mechanism 100, and consequently reduces the size of the smart glasses 200.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
