Abstract
Description
Technical Field
[0001] This invention relates to the field of head-mounted display technology, and particularly to an interpupillary distance adjustment component and a head-mounted display device. Background Technology
[0002] Currently, head-mounted electronic devices are becoming increasingly widely used in people's lives. However, depending on the user, the interpupillary distance (IPD) of these devices needs to be adjusted so that the lens is directly facing the user's eyes. This requires an adjustment mechanism to adjust the IPD. However, existing adjustment mechanisms all move the lens of the left eye and the right eye simultaneously. Current research shows that the interpupillary distance of a person is not asymmetrical, and some people even have strabismus or asymmetry between their left and right eyes. Therefore, existing head-mounted electronic devices cannot fully meet the needs of the users. Summary of the Invention
[0003] The present invention provides an interpupillary distance adjustment component and a head-mounted display device, which enables the left lens and the right lens of the head-mounted display device to be adjusted independently, thereby meeting the user's needs.
[0004] To achieve the above objectives, the present invention provides the following technical solution:

The first adjustment component is connected to the first lens body, and the second adjustment component is connected to the second lens body. The drive unit has a first motion state and a second motion state relative to the bracket body. When the drive unit is in the first motion state, the drive unit drives the first lens body to move toward the second lens body through the first adjustment component. When the drive unit is in the second motion state, the drive unit drives the second lens body to move toward the first lens body through the second adjustment component.
[0009] This invention divides the lens assembly into a first lens body and a second lens body, both of which are rotatably connected to a support body. In use, the first lens body can be positioned for the user's left eye, and the second lens body for the user's right eye. When the distance between the first and second adjustment components needs adjustment, the adjustment components in this invention can adjust the first and second lens bodies respectively. Specifically, the adjustment components include a first adjustment component for adjusting the first lens body and a second adjustment component for adjusting the second lens body, allowing the first and second lens bodies to move in opposite directions under the action of the sliding component. This further makes the distance between the first and second lens bodies adjustable, facilitating the use of users with different interpupillary distances and broadening the application scope of this invention.
[0010] Optionally, the driving unit includes a rolling wheel and a sleeve, the sleeve passing through the rolling wheel. The rolling wheel has a first surface and a second surface disposed opposite to each other. A first active ratchet is disposed on the first surface, and a second active ratchet is disposed on the second surface. When the driving unit is in a first motion state, the rolling wheel drives the first adjusting component along a first direction through the first active ratchet. When the driving unit is in a second motion state, the rolling wheel drives the second adjusting component along a second direction through the second active ratchet. The first direction is opposite to the second direction.
[0011] Optionally, the adjustment assembly further includes a first rotating wheel, which is disposed between the rolling wheel and the first adjustment assembly.

Detailed Implementation
[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please refer to Figures 1-2 ,in Figure 1 This is an exploded view of some components of the overall structure of an interpupillary distance adjustment component provided in an embodiment of the present invention. Figure 2 This is a three-dimensional schematic diagram of a component part of the overall structure of an interpupillary distance adjustment component provided in an embodiment of the present invention;
[0026] An embodiment of the present invention provides an interpupillary distance adjustment component, comprising:
[0027] Lens assembly, bracket body 1, sliding assembly, and adjustment assembly;
[0028] The lens assembly includes a first lens body 2 and a second lens body 3, both of which are mounted on the bracket body 1 via a sliding component.
[0029] The adjustment assembly includes a drive unit, a first adjustment component, and a second adjustment component. The drive unit is connected to the first adjustment component and the second adjustment component, respectively. The first adjustment component is connected to the first lens body 2, and the second adjustment component is connected to the second lens body 3. The drive unit has a first motion state and a second motion state relative to the bracket body 1. When the drive unit is in the first motion state, the drive unit drives the first lens body 2 to move toward the second lens body 3 through the first adjustment component. When the drive unit is in the second motion state, the drive unit drives the second lens body 3 to move toward the first lens body 2 through the second adjustment component, so that the first lens body and the second lens body can be adjusted separately through the first motion state and the second motion state of the drive unit, respectively.
[0030] This invention divides the lens assembly into a first lens body 2 and a second lens body 3, and both the first lens body 2 and the second lens body 3 are rotatably connected to the support body 1. In use, the first lens body 2 can be positioned for the user's left eye, while the second lens body 3 can be positioned for the user's right eye. When it is necessary to adjust the distance between the first adjustment component and the second adjustment component, the adjustment components in this application can adjust the first lens body 2 and the second lens body 3 respectively. Specifically, the adjustment components in this application include a first adjustment component for adjusting the first lens body 2 and a second adjustment component for adjusting the second lens body 3, so that the first lens body 2 and the second lens body 3 can move in opposite directions under the action of the sliding component. This further makes the distance between the first lens body 2 and the second lens body 3 adjustable, which is convenient for users with different interpupillary distances and makes the application scope of this invention wider.
[0031] In one possible implementation, please refer to Figure 2 The driving unit includes a rolling wheel 4 and a sleeve 11, with the sleeve 11 penetrating the rolling wheel 4. The rolling wheel 4 has a first surface and a second surface arranged opposite to each other. A first active ratchet 41 is provided on the first surface, and a second active ratchet 42 is provided on the second surface. When the driving unit is in a first movement state, the rolling wheel 4 drives the first adjustment component along the first direction through the first active ratchet 41. When the driving unit is in a second movement state, the rolling wheel 4 drives the second adjustment component along the second direction through the second active ratchet 42. The first direction and the second direction are opposite. In the above structure, the first active ratchet 41 and the second active ratchet 42 are provided on the two mutually distant sides of the rolling wheel 4. The teeth of the two active ratchets are arranged in opposite directions. That is, when the rolling wheel 4 performs the above-mentioned first direction movement or second direction movement, the first direction movement can be clockwise, and the second direction movement... The direction can be counterclockwise. This application does not specifically limit the first direction movement and the second direction movement, as long as the first direction movement and the second direction movement are opposite. In the above-mentioned movement process, since the tooth directions of the first active ratchet 41 and the second active ratchet 42 are opposite, the first active ratchet 41 only engages with the first adjustment component when the rolling wheel 4 is in the first direction movement or the second direction movement. Similarly, the second active ratchet 42 is also like this. Therefore, the first active ratchet 41 and the second active ratchet 42 can drive the first adjustment component and the second adjustment component respectively, thereby driving the sliding component of the first lens body 2 or the second lens body 3 to move in opposite directions, thereby making the distance between the first lens body 2 and the second lens body 3 adjustable to meet the usage needs of users with different interpupillary distances.
[0032] In one possible implementation, please refer to Figure 2 The adjustment assembly also includes a first rotating wheel 5, which is disposed between the rolling wheel 4 and the first adjustment assembly. The first rotating wheel 5 has a first driven ratchet 51 on the side facing the rolling wheel 4. The first driven ratchet 51 meshes with the first driving ratchet 41. In the above structure, in order to satisfy that the rolling wheel 4 can drive the first adjustment assembly in the first direction of movement, the present application adds a first rotating wheel 5 for connecting the rolling wheel 4 and the first adjustment assembly. The first rotating wheel 5 is used to transfer the force applied by the user to the rolling wheel 4 in different directions to the first adjustment assembly, thereby enabling the first adjustment assembly to drive the first lens body 2 to move and complete the driving of the first lens body 2.
[0033] In one feasible approach, please refer to [further details]. Figure 2 The adjustment assembly also includes a second rotating wheel 7, which is disposed between the rolling wheel 4 and the second adjustment assembly. A second driven ratchet 71 is provided on the side of the second rotating wheel 7 facing the rolling wheel 4, and the second driven ratchet 71 meshes with a second driving ratchet 42. In the above structure, to ensure that the rolling wheel 4 can drive the second adjustment assembly in the second direction of movement, this application adds a second rotating wheel 7 for connecting the rolling wheel 4 and the second adjustment assembly. The second rotating wheel 7 is used to transfer the force applied by the user to the rolling wheel 4 in different directions to the second adjustment assembly, thereby enabling the second adjustment assembly to drive the second lens body 3 to move, thus completing the driving of the second lens body 3.
[0034] In one possible implementation, please refer to Figure 3 The first adjustment component includes a first connecting rod 6 and a first rotating shaft 61. The first rotating shaft 61 is used to connect the first connecting rod 6 and the first rotating wheel 5, and the first connecting rod 6 is used to hinge with the first lens body 2. In this application, the first connecting rod 6 is fixed to the first rotating wheel 5 through the first rotating shaft 61, and the first rotating shaft 61 is located at the eccentric position of the first rotating wheel 5. Thus, when the first rotating wheel 5 rotates, it will drive the first connecting rod 6 to perform a crank-rocker reciprocating motion on the first lens body 2, so as to drive the first lens body 2 to move.
[0035] In one possible implementation, please refer to Figure 4 The second adjustment component includes a second connecting rod 8 and a second rotating shaft 81. The second rotating shaft 81 is used to connect the second connecting rod 8 and the second rotating wheel 7, and the second connecting rod 8 is used to hinge with the second lens body 3. In this application, the second connecting rod 8 is fixed to the second rotating wheel 7 through the second rotating shaft 81, and the second rotating shaft 81 is located at the eccentric position of the second rotating wheel 7. Thus, when the second rotating wheel 7 rotates, it will drive the second connecting rod 8 to perform a crank-rocker reciprocating motion on the second lens body 3, so as to drive the second lens body 3 to move.
[0036] In one possible implementation, the first link 6 is connected to the first lens body 2 by a connecting buckle 10, and the second link 8 is connected to the second lens body 3 by a connecting buckle 10. In this application, both the first link 6 and the second link 8 are connected by connecting buckles 10. However, it is worth noting that the fixing method is not limited to screws, glue, or heat fusion. The purpose of using connecting buckles 10 in this application is to enable the first link 6 and the second link 8 to drive the first lens body 2 and the second lens body 3.
[0037] In one possible implementation, the sliding component includes a sliding shaft 9, which is disposed on the side of the bracket body 1 near the adjustment component, for slidingly connecting the first lens body 2 and the second lens body 3. In the above structure, the sliding component of this application can be a single sliding shaft 9. The first lens body 2 and the second lens body 3 in this application are both disposed on a single sliding shaft 9, so that the first lens body 2 and the second lens body 3 can slide in opposite directions on the sliding shaft 9.
[0038] In one possible implementation, the sliding assembly includes two sliding shafts 9. One sliding shaft 9 is located on the side of the bracket body 1 near the adjustment assembly and is used to slide and connect the first lens body 2 and the second lens body 3. The other sliding shaft 9 is located on the side of the bracket body 1 away from the adjustment assembly and is used to slide and connect the first lens body 2 and the second lens body 3. In the above structure, the sliding assembly of this application can have multiple sliding shafts 9. The purpose of this arrangement is to improve the stability of the sliding of the first lens body and the second lens body 3 on the sliding shafts 9.
[0039] In one possible implementation, the adjustment process between the first lens body 2 and the second lens body 3 of this application is described in general:
[0040] First, the user adjusts the position between the first lens body 2 and the second lens body 3 according to their own needs. When the position of the first lens body 2 needs to be changed, the rolling wheel 4 is rotated clockwise. The first driving ratchet 41 of the rolling wheel 4 pushes the first driven ratchet 51 of the first rotating wheel 5 to rotate clockwise. Since the axis of the first connecting rod 6 is fixed on the first rotating wheel 5, the first connecting rod 6 drives the first lens body 2 to achieve crank-like motion. When the rolling wheel 4 is rotated clockwise, the second driven ratchet 71 of the second rotating wheel 7 is pushed away by the second driving ratchet 42 of the rolling wheel 4, thus preventing linkage. Conversely, when the rolling wheel is rotated counterclockwise, the second driven ratchet 71 of the second rotating wheel 7 is driven by the second driving ratchet 42 of the rolling wheel 4, thus achieving the second connecting rod 8 driving the second lens body 3 to achieve crank-like reciprocating motion. When the rolling wheel is rotated counterclockwise, the first driven ratchet 51 of the first rotating wheel 5 is pushed away by the first driving ratchet 41 of the rolling wheel 4. Through the forward and reverse linkage, the function of independent adjustment of the left and right lens barrels is realized.
[0041] Secondly, the present invention also provides a head-mounted display device, including a head-mounted display device body and an interpupillary distance adjustment component as described above. The bracket body 1 of the interpupillary distance adjustment component is mounted on the head-mounted display device body. The application of this application is not limited to the interpupillary distance adjustment component. It can be applied to components such as the head-mounted display device body and can be installed and used according to actual needs.
[0042] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
