DETAILED DESCRIPTION

[0026] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, but cannot be understood as limiting the present application.

[0027] The embodiments of the present application can be applied to various application scenarios such as extended reality (Extended Reality, XR), virtual reality (Virtual Reality, VR), augmented reality (Augmented Reality, AR), and mixed reality (Mixed Reality, MR).

[0028] Among them, Extended Reality (XR) is a concept that includes Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR). It refers to the technology that creates an environment in which the virtual world is connected to the real world, and users can interact with the environment in real time.

[0029] Devices used to achieve extended reality are usually called extended reality devices, among which the more common ones are virtual reality devices, which are also called VR devices. VR devices are terminals that achieve virtual reality effects, and can usually be provided in the form of VR glasses, helmet-mounted displays (Head Mount Display, HMD), and contact lenses to achieve visual perception and other forms of perception. Of course, the form of virtual reality devices is not limited to this, and can be further miniaturized or enlarged as needed.

[0030] The VR device may also include a handle controller. As a peripheral device of the VR device, the handle controller is used for the user to operate and control the characters and environment of the virtual environment presented by the VR glasses.

[0031] In the related art, the handle controller is usually provided with a ring-shaped light ring shell, and the light ring shell can be arranged around the circumference of the handle controller. A strip-shaped FPC (Flexible Printed Circuit) can be arranged in the light ring shell, and a plurality of infrared lamps are arranged on the FPC. The number of infrared lamps is generally 10 or more, and the infrared lamps are distributed along the circumference of the light ring shell. Among them, the light ring shell is made of infrared transparent material, so that the infrared light emitted by the infrared lamp can form an aperture through the light ring shell, and the positioning and tracking of the handle controller can be achieved by tracking the infrared aperture. However, in the above-mentioned handle controller, since a large number of infrared lamps and a long FPC are provided, the power consumption of the handle controller is large, the battery life of the handle controller is low, and the cost of the handle controller is high.

[0032] In order to overcome at least one of the above technical problems, the embodiments of the present application provide a light-emitting device and a handle controller for positioning. By setting a mounting hole on the housing of the handle controller, setting a light-guiding column in the mounting hole, and setting a light-guiding bracket and a light source in the housing, the light emitted by the light source can be irradiated to the light-guiding column through the light-guiding bracket, and the light can be transmitted through the light-guiding column and displayed as an aperture outside the housing and around the mounting hole. By tracking the aperture, the positioning and tracking of the handle controller is achieved. The above-mentioned light-emitting device and handle controller for positioning use a relatively small number of light sources, and utilize a light-guiding light-guiding bracket and a light-transmitting light-guiding column. When the light source is working, the aperture can be displayed at multiple mounting holes of the housing. There is no need to set an FPC for arranging the light source, and there is no need to set a light ring housing. Therefore, it is beneficial to reduce the power consumption of the handle controller, improve the battery life of the handle controller, simplify the structure of the handle controller, and reduce the cost of the handle controller.

[0033] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0034] The light emitting device for positioning provided in the embodiment of the present application is used for a handle controller, and can also be applied to other electronic devices having a light emitting device for positioning. For ease of description, the arrow X in the figure of this embodiment indicates the length direction, the arrow Y indicates the width direction, and the arrow Z indicates the depth direction.

[0035] Please refer to Figures 1 to 4 The light emitting device for positioning provided in this embodiment may include: a housing 1, a light guide column 2, a light source 4 and a light guide bracket 3. The inner space of the housing 1 is a receiving space 1a. The housing 1 is provided with a plurality of spaced mounting holes 1b, which are connected to the receiving space 1a. The light guide column 2 is installed in the mounting hole 1b. The light source 4 and the light guide bracket 3 are installed in the receiving space 1a.

[0036] The housing 1 may have a first end 1c and a second end 1d opposite to each other, and the first end 1c and the second end 1d are smoothly connected. The volume of the internal space of the first end 1c of the housing 1 may be greater than the volume of the internal space of the second end 1d of the housing 1. A light source 4 and a light guide bracket 3 may be disposed in the first end 1c of the housing 1, and other components of the handle controller such as a sensor, a control panel, etc. may also be disposed. The second end 1d of the housing 1 may serve as a gripping end for a user to hold, and a battery module, etc. may be disposed in the second end 1d of the housing 1.

[0037] The housing 1 may have a plurality of housings connected to facilitate assembly of the handle controller. For example, the housing 1 has two housings connected to each other, and the two housings are detachably connected to facilitate inspection or replacement of the components in the housing 1.

[0038] The housing 1 is provided with a plurality of mounting holes 1b. The plurality of mounting holes 1b may be distributed at intervals. For example, at least some of the plurality of mounting holes 1b may be distributed at intervals along the width direction of the housing 1. Alternatively, at least some of the plurality of mounting holes 1b may be distributed at intervals along the length direction of the housing 1. Alternatively, the plurality of mounting holes 1b may be distributed at intervals along the circumference of the housing 1. The specific distribution of the mounting holes 1b is not limited thereto, and this embodiment is only used as an example.

[0039] A light guide column 2 may be provided in the mounting hole 1b. The light guide column 2 may be roughly cylindrical. The light guide column 2 may be made of a material with good light transmittance. Exemplarily, the number of light guide columns 2 is equal to the number of mounting holes 1b. That is, a light guide column 2 is provided in each mounting hole 1b, and the light guide column 2 is used for allowing light emitted by the light source 4 of the housing 1 to pass through, so as to display a light spot 5 around the corresponding mounting hole 1b. The light spot 5 may be an annular aperture, or the light spot 5 may also be in other shapes such as a circle. It should be noted that the light spot 5 in the figure is only used to illustrate the display effect of the light-emitting device for positioning, and the light spot 5 does not constitute the structure of the light-emitting device for positioning.

[0040] In some examples, the light guide column 2 is interference fit with the mounting hole 1b. In other examples, the light guide column 2 can be fixed in the mounting hole 1b by bonding or clamping.

[0041] The light source 4 in the housing 1 can be an infrared lamp for emitting infrared light, or can be a light source capable of emitting other visible light. Exemplarily, a control board is also provided in the housing 1, and the light source 4 is mounted on the surface of the control board. For example, the light source 4 can be mounted on the surface of the control board using SMT (Surface Mount Technology).

[0042] The number of light sources 4 is greater than or equal to 1, and the number of light sources 4 is less than or equal to 3. In some embodiments, among the multiple mounting holes 1b of the housing 1, at least some of the mounting holes 1b may be located on the same spherical surface, and at least some of the light sources 4 may be located at the center of the sphere corresponding to the spherical surface, so that the light source 4 is at an equal distance from the light guide column 2 in the mounting hole 1b located on the same spherical surface, which is conducive to the optical parameters of the light emitted by the light source 4 being equal when it reaches the light guide column 2 located on the same spherical surface.

[0043] The term "equal" in this embodiment can be understood as being the same or the difference between the two being within a preset range. For example, the optical parameters of the light emitted by the light source 4 when reaching the light guide column 2 located on the same spherical surface are equal, which can be understood as the optical parameters of the light emitted by the light source 4 when reaching the light guide column 2 located on the same spherical surface are the same, or the difference between the optical parameters of the light emitted by the light source 4 when reaching the light guide column 2 located on the same spherical surface is within a preset range.

[0044] Exemplarily, when there is only one light source 4 and the number of mounting holes 1b on one spherical surface is greater than the number of mounting holes 1b on the other spherical surface, the light source 4 is disposed at the center of the sphere corresponding to the spherical surface where the larger number of mounting holes 1b are located.

[0045] When there are two light sources 4, a portion of the mounting holes 1b are located on one spherical surface, and another portion of the mounting holes 1b are located on another spherical surface. The two light sources 4 can be respectively arranged at the centers of the two spherical surfaces.

[0046] When there are two light sources 4, one part of the mounting holes 1b is located on one spherical surface, one part of the mounting holes 1b is located on another spherical surface, and another part of the mounting holes 1b is located on another spherical surface. The three light sources 4 can be respectively arranged at the centers of the three spherical surfaces corresponding to the above-mentioned three spherical surfaces.

[0047] The specific arrangement of the light source 4 is not limited thereto, and this embodiment is only used as an example. In other embodiments, the light source 4 can also be arranged at other positions according to actual needs, for example, the light source 4 can be arranged at the geometric center of the first end 1c of the housing 1.

[0048] A light guide bracket 3 is provided between the light source 4 and the light guide column 2, and the light guide bracket 3 is made of a material with good light transmittance. The light guide bracket 3 is located in the first end 1c of the housing 1, and the light guide bracket 3 is located on the optical path of the light emitted by the light source 4 to the light guide column 2, so that the optical parameters of the light emitted by the light source 4 when reaching each light guide column 2 are equal, and then the display effect of the light spot 5 displayed at each mounting hole 1b is more uniform.

[0049] The light guide bracket 3 is installed in the accommodation space 1a in the housing 1. The light guide bracket 3 is located between the light source 4 and the light guide column 2, so that the optical parameters of the light emitted by the light source 4 when reaching each light guide column 2 are equal. For example, a coating is provided in a part of the light guide bracket 3 to change the light loss through the light guide bracket 3 through the coating, so that the optical parameters of the light emitted by the light source 4 when reaching each light guide column 2 are equal. Among them, the specific position and thickness of the coating are set according to the distance between the light source 4 and each mounting hole 1b.

[0050] The light-emitting device for positioning provided in the present embodiment is provided with a housing 1, on which a plurality of spaced mounting holes 1b are provided; a plurality of light-guiding columns 2, which are respectively installed in the plurality of mounting holes 1b; a light source 4, which is installed in the accommodation space 1a of the housing 1; a light-guiding bracket 3, which is installed in the accommodation space 1a in the housing 1, and which is located between the light source 4 and the light-guiding column 2, so that the optical parameters of the light emitted by the light source 4 when reaching each light-guiding column 2 are equal. In this way, by using a relatively small number of light sources 4, when the light source 4 is working, the light-guiding light-guiding bracket 3 and the light-transmitting light-guiding column 2 can all display light spots 5 of equal and uniform size at the plurality of mounting holes 1b of the housing 1, and there is no need to set up an FPC for arranging the light source 4, nor is there any need to set up a lamp ring housing, thereby helping to reduce the power consumption of the light-emitting device for positioning, improve the battery life of a handle controller having the light-emitting device for positioning, simplify the structure of the handle controller, and reduce the cost of the handle controller.

[0051] Please continue Figure 3 to Figure 4 In some embodiments, the light guide bracket 3 may be in the shape of a cover. The wall thickness of the portion of the light guide bracket 3 located in the optical path from the light source 4 to the mounting hole 1b is inversely proportional to the distance between the light source 4 and the mounting hole 1b. The greater the distance between the light source 4 and the mounting hole 1b, the smaller the wall thickness of the portion of the light guide bracket 3 located in the optical path from the light source 4 to the mounting hole 1b, so that the light loss of the infrared light emitted by the light source 4 when reaching the light guide columns 2 in each mounting hole 1b is equal, and then the optical parameters of the light emitted by the light source 4 when reaching each light guide column 2 are equal.

[0052] Exemplarily, the mounting holes 1 b include a first type of holes and a second type of holes; wherein the distance between the first type of holes and the light source 4 is smaller than the distance between the second type of holes and the light source 4 .

[0053] The light guide bracket 3 has a first light guide wall located between the light source 4 and the first type of hole 1b, and a second light guide wall located between the light source 4 and the second type of hole 1b, and the wall thickness of the first light guide wall is greater than the wall thickness of the second light guide wall, so that the light loss of the light emitted by the light source 4 when reaching each light guide column 2 is equal. That is, the wall thickness of the portion of the light guide bracket 3 located between the first type of hole and the light source 4 is greater than the wall thickness of the portion of the light guide bracket 3 located between the second type of hole and the light source 4, so that the light loss of the infrared light emitted by the light source 4 when reaching each light guide column 2 is equal.

[0054] For example, taking the light source 4 as an example: the second type of holes may include multiple, and the multiple second type of holes may be located on the same spherical surface. The light source 4 may be arranged at the center of the sphere corresponding to the spherical surface. The wall thickness of the portion of the light guide bracket 3 located in the optical path of the light emitted by the light source 4 to each second type of hole may be equal, so that the light loss of the light emitted by the light source 4 to the light guide column 2 in each second type of hole is equal, so that the optical parameters of the light emitted by the light source 4 when it reaches the light guide column 2 in each second type of hole are equal.

[0055] The first type of hole may have one or more. The distance between the first type of hole and the light source 4 is smaller than the distance between the second type of hole and the light source 4, and the wall thickness of the portion of the light guide bracket 3 located in the optical path from the light source 4 to each second type of hole may be smaller than the wall thickness of the portion of the light guide bracket 3 located in the optical path from the light source 4 to each first type of hole. That is, the wall thickness of the portion of the light guide bracket 3 located in the optical path from the light source 4 to each first type of hole is greater than the wall thickness of the portion of the light guide bracket 3 located in the optical path from the light source 4 to each second type of hole.

[0056] Among them, the difference between the wall thickness of the part of the light guide bracket 3 located in the optical path from the light emitted by the light source 4 to each first-class hole and the wall thickness of the part of the light guide bracket 3 located in the optical path from the light emitted by the light source 4 to each second-class hole can be set according to actual needs, for example, the distance between the light source 4 and each first-class hole and second-class hole is set, and this embodiment is not specifically limited here.

[0057] In the above example, when there are multiple first-class holes, the distances between the multiple first-class holes and the light source 4 can be equal, and the wall thickness of the portion of the light guide bracket 3 located in the light path from the light source 4 to each second-class hole can be equal. The distances between the multiple first-class holes and the light source 4 can also be unequal, and the wall thickness of the portion of the light guide bracket 3 located in the light path from the light source 4 to each second-class hole is also unequal, wherein the greater the distance between the first-class hole and the light source 4, the smaller the wall thickness of the portion located in the light path from the light source 4 to the first-class hole.

[0058] When there are two light sources 4, the first type of holes may include multiple holes, and the multiple first type of holes may be located on the same spherical surface, and a light source 4 is disposed at the center of the spherical surface. For ease of description, the light source 4 is described as the first light source 4. The second type of holes may include multiple holes, and the multiple second type of holes may be located on the same spherical surface, and a light source 4 is disposed at the center of the spherical surface. For ease of description, the light source 4 is described as the second light source 4.

[0059] The wall thickness of the light guide bracket 3 can be set according to the distance between the first type of hole and the first light source 4, the distance between the first type of hole and the second light source 4, the distance between the second type of hole and the first light source 4, and the distance between the second type of hole and the second light source 4.

[0060] For example, when the sum of the distance between the first type of hole and the first light source 4 and the distance between the first type of hole and the second light source 4 is smaller than the sum of the distance between the second type of hole and the first light source 4 and the distance between the second type of hole and the second light source 4, the wall thickness of the light guide bracket 3 in the optical path corresponding to the first type of hole is greater than the wall thickness of the light guide bracket 3 in the optical path corresponding to the second first type of hole.

[0061] When the number of light sources 4 is greater, the implementation process is similar to that of the above example, and will not be described in detail in this embodiment.

[0062] In other embodiments, taking the light source 4 as an example, the distance between the first type of hole and the light source 4 is smaller than the distance between the second type of hole and the light source 4. The portion of the light guide bracket 3 located between the first type of hole and the light source 4 is provided with a coating, so that the light loss in the optical path from the light emitted by the light source 4 to the light guide column 2 in the first type of hole is increased through the coating, so that the light loss of the infrared light emitted by the light source 4 when reaching each light guide column 2 is equal. Alternatively, the thickness of the coating of the portion of the light guide bracket 3 located between the first type of hole and the light source 4 is greater than the thickness of the coating of the portion of the light guide bracket 3 located between the second type of hole and the light source 4, so that the light loss of the infrared light emitted by the light source 4 when reaching each light guide column 2 is equal.

[0063] Please continue to refer to Figures 1 to 4 In some embodiments, the housing 1 includes a first shell 11 and a second shell 12, which are connected to form a receiving space 1a; wherein the first shell 11 and the second shell 12 are respectively provided with a plurality of spaced-apart mounting holes 1b.

[0064] The first shell 11 may have an upper opening, and the second shell 12 is covered on the upper opening of the first shell 11 , so that the first shell 11 and the second shell 12 enclose a relatively closed accommodation space 1 a .

[0065] Please refer to Figure 5 and Figure 6The first shell 11 includes a receiving wall 111, a first end wall 112 is provided at one end of the receiving wall 111 close to the first end 1c of the shell 1, and a second end wall 113 is provided at one end of the receiving wall 111 close to the second end 1d of the shell 1. Part of the receiving wall 111 is recessed in a direction away from the second shell 12, and a middle area of ​​the receiving wall 111 between the left and right sides is recessed in a direction away from the second shell 12 to form a relatively large internal space, which constitutes at least part of the receiving space 1a of the shell 1.

[0066] The accommodating wall 111, the first end wall 112 and the second end wall 113 are arranged to form an upper opening toward the edge of the second shell 12, and the accommodating wall 111, the first end wall 112 and the second end wall 113 are connected to the second shell 12 toward the edge of the second shell 12. The surface area of ​​the first end wall 112 is greater than the surface area of ​​the second end wall 113. The first end wall 112 is provided with a plurality of installation holes 1b distributed at intervals, and the portion of the second shell 12 close to the first end wall 112 is provided with a plurality of installation holes 1b distributed at intervals.

[0067] For example, the plurality of mounting holes 1b on the first end wall 112 may be distributed in one or more rows, and the mounting holes 1b in the same row may be located on the same spherical surface. Similarly, the plurality of mounting holes 1b in the portion of the second housing 12 close to the first end wall 112 may be distributed in one or more rows, and the mounting holes 1b in the same row may be located on the same spherical surface.

[0068] Of course, the distribution of the mounting holes 1b is not limited to this, and this embodiment is only used as an example. For example, in other examples, the mounting holes 1b may also be distributed on the first end wall 112 and may be distributed in multiple rows; or, the mounting holes 1b may also be distributed in the portion of the second housing 12 close to the first end wall 112 and may be distributed in multiple rows.

[0069] In some embodiments, the light guide bracket 3 includes: a first light guide plate 31 and a second light guide plate 32 connected to each other, and the first light guide plate 31 is connected to the second light guide plate 32. Part of the first light guide plate 31 constitutes a first light guide wall, and the first light guide wall is located in the light path from the light emitted by the light source 4 to the light guide column 2 set in the mounting hole 1b of the first end wall 112. The shape of the first light guide plate 31 of the light guide bracket 3 is adapted to the shape of the first end wall 112, and the first light guide plate 31 can be arranged close to the inner side surface of the first end wall 112 to improve the compactness of the layout inside the housing 1.

[0070] The second light guide plate 32 is connected to the side of the first light guide plate 31 facing the second shell 12, and the second light guide plate 32 is folded relative to the first light guide plate 31 in a direction away from the first end wall 112 (that is, in a direction toward the accommodating space 1a). Part of the second light guide plate 32 constitutes a second light guide wall, and the second light guide wall is located in the optical path from the light emitted by the light source 4 to the light guide column 2 set in the mounting hole 1b of the second shell 12. The shape of the second light guide plate 32 is adapted to the shape of the part of the second shell 12 where the mounting hole 1b is set, so as to improve the compactness of the layout inside the shell 1.

[0071] For example, there is one light source 4, the mounting hole 1b provided on the first end wall 112 is a first type of hole, and the mounting hole 1b provided on the second shell 12 is a second type of hole. The light source 4 can be provided at the center of the sphere corresponding to the spherical surface where the first type of hole is located. When the distance between the first type of hole and the light source 4 is smaller than the distance between the second type of hole and the light source 4, the wall thickness of the first light guide plate 31 can be larger than the wall thickness of the second light guide plate 32. When the distance between the first type of hole and the light source 4 is larger than the distance between the second type of hole and the light source 4, the wall thickness of the first light guide plate 31 can be smaller than the wall thickness of the second light guide plate 32

[0072] The remaining sides of the first light guide plate 31 are further connected with folded edges 33, which are folded relative to the first light guide plate 31 in a direction away from the first end wall 112. The folded edges 33 can improve the strength of the light guide bracket 3 and reduce deformation of the light guide bracket 3.

[0073] In the above example, the first light guide plate 31, the second light guide plate 32 and the folded edge 33 can be integrally provided, and specifically can be integrally formed by using a commonly used light guide material through an injection molding process. The light guide material can be plastic such as PC (Polycarbonate), and when the light source 4 is an infrared lamp, the infrared transmittance of the light guide bracket 3 can reach up to 90%.

[0074] In addition, one of the portions of the light guide bracket 3 that are not in the optical path of the light emitted by the light source 4 to the light guide column 2 in each mounting hole 1b and the portion of the inner side surface of the housing 1 corresponding to the phase slot is provided with a limiting slot and the other is provided with a limiting protrusion that cooperates with the limiting slot. Through the cooperation of the limiting protrusion and the limiting slot, the light guide bracket 3 can be kept in the corresponding position to prevent the light guide bracket 3 from being offset relative to the mounting hole 1b.

[0075] Exemplarily, the portion of the light guide bracket 3 that is not in the optical path from the light emitted by the light source 4 to the light guide column 2 in each mounting hole 1b can be provided with a limiting groove, and the portion of the inner side surface of the housing 1 corresponding to the phase groove can be provided with a limiting protrusion; of course, the limiting protrusion can also be provided on other components located in the accommodating space 1a. Alternatively, the portion of the light guide bracket 3 that is not in the optical path from the light emitted by the light source 4 to the light guide column 2 in each mounting hole 1b can be provided with a limiting protrusion, and the portion of the inner side surface of the housing 1 corresponding to the phase groove can be provided with a limiting groove; of course, the limiting groove can also be provided on other components located in the accommodating space 1a.

[0076] In the above example, there may be one or more light guide brackets 3. When there are multiple light guide brackets 3, the multiple light guide brackets 3 may be spaced apart, or the multiple light guide brackets 3 may be stacked, and the multiple light guide brackets 3 all function to make the optical parameters of the light emitted by the light source 4 equal when reaching each light guide column 2. For example, when the curved surface shape of each mounting hole 1b is relatively complex, the above function may be achieved by setting multiple light guide brackets 3.

[0077] In other examples, the light guide bracket 3 can also be bonded to the inner side of the housing 1 to improve the installation reliability of the light guide bracket 3. Alternatively, each edge of the first light guide plate 31 can extend to the corresponding edge of the first end wall 112, and a shallow groove is set on the second shell 12 and the first shell 11, and the second light guide plate 32 cooperates with the shallow groove on the second shell 12, and the folding plate cooperates with the shallow groove on the first shell 11, which plays a role in limiting the light guide bracket 3. Alternatively, the cross-sectional area of ​​the first shell 11 can be gradually reduced from the first end 1c toward the second end 1d. At this time, each edge of the first light guide plate 31 can extend to the corresponding edge of the first end wall 112, and the first light guide plate 31 cannot move to an area with a smaller cross-sectional area, thereby achieving the limitation of the light guide bracket 3.

[0078] The light emitting device for positioning provided in this embodiment is used as an example of a handle controller. When the handle controller needs to be positioned and tracked, the control panel controls the light source 4 such as an infrared lamp to light up, and the infrared light emitted by the infrared lamp reaches the light guide column 2 through the light guide bracket 3, and the light spot 5 is displayed outside the housing 1 through the light guide column 2; other external devices track the infrared light spot 5, thereby realizing the positioning and tracking of the handle controller. In the process of the infrared light emitted by the infrared lamp reaching the light guide column 2 through the light guide bracket 3, when the distance between the infrared lamp and the light guide column 2 is small, the wall thickness of the part of the light guide bracket 3 located in the light path formed between the two is relatively large; when the distance between the infrared lamp and the light guide column 2 is large, the wall thickness of the part of the light guide bracket 3 located in the light path formed between the two is relatively small, so that when the infrared light emitted by the infrared lamp reaches each light guide column 2 through the light guide bracket 3, the light loss of the infrared light is equal, so that the optical parameters such as the light intensity of the infrared light are equal, thereby ensuring that the size of the light spot 5 displayed from the light guide column 2 is equal and uniform, thereby improving the display effect.
