[0002] This application claims priority to Chinese Patent Application No. 202510124413.9, filed on January 26, 2025, entitled "Binocular Optical Device", the entire contents of which are incorporated herein by reference. Technical Field
[0003] This application relates to the field of optical equipment technology, and more particularly to a binocular optical device. Background Technology
[0004] Binocular optical devices include Extended Reality (XR) devices and binocular detection devices. Binocular optical devices mainly consist of a first optical engine and a second optical engine. To improve the usability of binocular optical devices, generally speaking, the first and second optical engines need to be aligned with the user's pupils respectively.
[0005] In related technologies, the first and second optical engines are driven by a driver, which drives the first and second optical engines to move synchronously, thereby moving closer to or further away from each other, in order to adjust the distance between the optical axes of the first and second optical engines so that the first and second optical engines are opposite to the user's pupils.
[0006] Because the human eye is typically asymmetrical in its physiological structure, when one optical engine moves to a position where its optical axis aligns with the pupil, it cannot be guaranteed that the optical axis of the other optical engine will also align perfectly with the pupil on the other side. In other words, binocular optical devices in related technologies struggle to ensure that the optical axes of both optical engines are simultaneously aligned with both pupils. This results in visual distortion and accelerated eye strain for users when using binocular optical devices. Summary of the Invention

Detailed Implementation
[0037] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0039] Furthermore, although the terminology used in this application is selected from commonly known and used terms, some terms mentioned in this application specification may have been selected by the applicant at his or her own discretion, and their detailed meanings are explained in the relevant sections of this description.
[0040] Furthermore, this application is required to be understood not only through the actual terms used, but also through the meaning implied by each term.
[0041] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.
[0042] This application provides a binocular optical device. Referring to Figures 1 to 11, the binocular optical device 1 provided in this application includes: a driver 100, a transmission assembly 200, a first optical engine 300, and a second optical engine 400. Exemplarily, when the binocular optical device 1 is an extended reality device, both the first optical engine 300 and the second optical engine 400 are optical modules capable of displaying images.
[0043] In the embodiments of this application, the driver 100 is driven to the first optical engine 300 and the second optical engine 400 via the transmission assembly 200. The transmission assembly 200 has a first transmission state and a second transmission state. When the transmission assembly 200 is in the first transmission state, the driver 100 drives the first optical engine 300 and the second optical engine 400 to move closer to or further away from each other via the transmission assembly 200. When the transmission assembly 200 is in the second transmission state, the driver 100 drives the second optical engine 400 to move via the transmission assembly 200, and the power transmission between the driver 100 and the first optical engine 300 is cut off.
[0044] In this manner, using the solution provided in the embodiments of this application, when the transmission component 200 is in the first transmission state, the power of the driver 100 can be normally transmitted to the first optical engine 300 and the second optical engine 400, thereby driving the first optical engine 300 and the second optical engine 400 to move synchronously. When the transmission component 200 is in the second transmission state, the power of the driver 100 is normally transmitted to the second optical engine 400, thereby driving the second optical engine 400 to move; the power transmission between the driver 100 and the first optical engine 300 is cut off, so that the first optical engine 300 will not move while the driver 100 is driving the second optical engine 400 to move.
[0045] This allows for differentiated adjustment of the positions of the first optical engine 300 and the second optical engine 400, ensuring that the optical axes of the first optical engine 300 and the second optical engine 400 are respectively aligned with the pupils of both eyes. For example, during the adjustment of the optical engine positions, the optical axis of the first optical engine 300 can first be aligned with one pupil. Then, the transmission assembly 200 can be switched from a first transmission state to a second transmission state, allowing for fine-tuning of the position of the second optical engine 400 so that its optical axis is aligned with the other pupil.
[0046] Therefore, compared with the binocular optical device 1 provided in this application embodiment, which can only adjust the two optical engines synchronously in related technologies, the binocular optical device 1 has the function of making the optical axis of the first optical engine 300 and the optical axis of the second optical engine 400 respectively opposite to the pupils of both eyes.
[0047] It should be noted that the specific methods for determining the pupil position and the adjustment scheme for adjusting the position of the optical engine based on the pupil position can be found in relevant technologies, which will not be elaborated here.
[0048] Referring to FIG1, in some embodiments, the transmission assembly 200 includes a power distribution mechanism 210 and a clutch mechanism 220. Referring to FIG2, the power distribution mechanism 210 is provided with a power input section 210a, a first power output section 210b, and a second power output section 210c. Combining FIG1 and FIG2, the driver 100 is drivenly connected to the power input section 210a, the first power output section 210b is connected to the first optomechanism 300 via the clutch mechanism 220, and the second power output section 210c is connected to the second optomechanism 400.
[0049] In this way, the power of the driver 100 can be distributed to the first optical engine 300 and the second optical engine 400 via the first power output unit 210b and the second power output unit 210c, respectively, thereby driving the first optical engine 300 and the second optical engine 400 to move. Furthermore, since a clutch mechanism 220 is provided between the first power output unit 210b and the first optical engine 300, the clutch mechanism 220 can be used to cut off or transmit power, so as to adjust the positions of the first optical engine 300 and the second optical engine 400 as needed.
[0050] It should be noted that the "clutch mechanism" described herein can be any mechanism capable of separately cutting off power and transmitting power. Therefore, the embodiments of this application do not limit the construction of the "clutch mechanism".
[0051] To help those skilled in the art better understand the solutions provided in the embodiments of this application, detailed examples are provided below for reference.
[0052] Referring to Figures 2 and 3, in some embodiments, the power distribution mechanism 210 includes a screw 211, a first sliding member 212, and a second sliding member 213. The screw 211 includes a first threaded portion 2111 and a second threaded portion 2112. The first sliding member 212 is threadedly connected to the first threaded portion 2111, and the second sliding member 213 is threadedly connected to the second threaded portion 2112. A power input portion 210a is disposed on the screw 211, a first power output portion 210b is disposed on the first sliding member 212, and a second power output portion 210c is disposed on the second sliding member 213.
[0053] Referring to Figure 2, for example, the power input section 210a is located at the left end of the screw 211. The driver 100 is a rotary motor, and the driver 100 is drively connected to the left end of the screw 211 to drive the screw 211 to rotate. Exemplarily, one of the first threaded portion 2111 and the second threaded portion 2112 is a left-hand thread, and the other is a right-hand thread. Thus, during the rotation of the screw 211, the screw 211 can drive the first sliding member 212 and the second sliding member 213 to move closer to or further away from each other.
[0054] Furthermore, for example, the first power output unit 210b is located at the lower end of the first slider 212, and the lower end of the first slider 212 is connected to the first base of the first optomechanism 300 via the clutch mechanism 220. The second power output unit 210c is located at the lower end of the second slider 213, and the lower end of the second slider 213 is connected to the second base of the second optomechanism 400. Thus, when the driver 100 is in the working state and the clutch mechanism 220 is in the power transmission state, the driver 100 can drive the first optomechanism 300 and the second optomechanism 400 to move. When the clutch mechanism 220 is in the power cut-off state, the driver 100 drives the second optomechanism 400 to move, while the position of the first optomechanism 300 remains unchanged.
[0055] Referring to Figures 2 and 3, in some embodiments, the power distribution mechanism 210 further includes a first slide bar 214 and a second slide bar 215 arranged at intervals and side by side. The first slide bar 214 and the second slide bar 215 respectively pass through a first sliding member 212, and the first slide bar 214 and the second slide bar 215 respectively pass through a second sliding member 213. The first sliding member 212 and the second sliding member 213 are arranged at intervals along the extending direction of the first slide bar 214. Thus, the first slide bar 214 and the second slide bar 215 can be used to slide and guide the first sliding member 212 and the second sliding member 213.
[0056] Referring to Figures 3 to 11, in some embodiments, the clutch mechanism 220 includes a first pressing member 221, an elastic member 222, and a pressing member driving structure 223. The first pressing member 221 is connected to the first optomechanism 300, so that when the first pressing member 221 is driven to move by the first sliding member 212, the first pressing member 221 can drive the first optomechanism 300 to move.
[0057] The elastic member 222 is used to apply a force to the first pressing member 221 to separate the first pressing member 221 from the first power output part 210b. The pressing member driving structure 223 is used to drive the first pressing member 221 to move toward the first power output part 210b so that the first pressing member 221 abuts against the first power output part 210b and moves synchronously with the first power output part 210b.
[0058] Taking Figures 8 and 9 as examples, the first pressing member 221 moves downward under the action of the pressing member driving structure 223, causing the first pressing member 221 to abut against the first sliding member 212. In this way, the frictional force between the first pressing member 221 and the first sliding member 212 can be used to make the first pressing member 221 move synchronously with the first sliding member 212, thereby driving the first optical engine 300 to move.
[0059] Taking Figures 10 and 11 as examples, after the pressing member drive structure 223 removes the downward force on the first pressing member 221, the first pressing member 221 moves upward under the elastic restoring force of the elastic member 222, thereby separating the first pressing member 221 from the first sliding member 212. This cuts off the power transmission between the first sliding member 212 and the first pressing member 221.
[0060] Referring to Figures 3 and 4, in some embodiments, the first optomechanism 300 includes a first base 310. Similarly, the second optomechanism 400 includes a second base. The transmission assembly 200 also includes a third slide bar 216. The third slide bar 216 extends in the same direction as the first slide bar 214. The first base 310 and the second base are slidably connected to the third slide bar 216, thereby allowing the third slide bar 216 to slide and guide the first optomechanism 300 and the second optomechanism 400.
[0061] Referring to Figures 3 to 11, in some embodiments, the first optomechanical unit 300 includes a first base 310. The pressing member drive structure 223 includes a second pressing member 2231.
[0062] The second pressing member 2231 includes a first wedge-shaped portion 2231a, and the second pressing member 2231 is slidably connected to the first seat 310. Exemplarily, the pressing member driving structure 223 further includes a sliding guide 2237. The sliding guide 2237 is fitted over the second pressing member 2231 and is connected to the first seat 310. Thus, by providing the sliding guide 2237, the second pressing member 2231 can be indirectly slidably connected to the first seat 310 via the sliding guide 2237.
[0063] Of course, in other embodiments, the sliding guide 2237 can be integrally formed on the first base 310, thus allowing the second pressing member 2231 to slide and engage with the first base 310. Alternatively, in other embodiments, the first base 310 may have a groove similar to the sliding guide 2237, with the second pressing member 2231 sliding and engaging with the groove, thus allowing the second pressing member 2231 to slide relative to the first base 310. Specific solutions for allowing the second pressing member 2231 to slide and engage with the first base 310 will not be listed here.
[0064] Furthermore, in embodiments of this application, the second pressing member 2231 is switchable between a first position and a second position. When the second pressing member 2231 is in the first position, the first wedge-shaped portion 2231a causes the first pressing member 221 to abut against the first power output portion 210b. When the second pressing member 2231 is in the second position, the elastic member 222 causes the first pressing member 221 to separate from the first power output portion 210b.
[0065] Taking Figures 9 and 11 as examples, the second pressing member 2231 can move left and right, switching between a first position and a second position. Figure 9 shows the second pressing member 2231 in the first position, and Figure 11 shows the second pressing member 2231 in the second position.
[0066] When the second pressing member 2231 moves from left to right to the first position, the first wedge-shaped portion 2231a drives the first pressing member 221 to move downward until the first pressing member 221 abuts against the first power output portion 210b. In this way, the friction between the first pressing member 221 and the first sliding member 212 can be used to make the first pressing member 221 move synchronously with the first sliding member 212, thereby driving the first optical engine 300 to move.
[0067] When the second pressing member 2231 moves from right to left to the second position, the first wedge-shaped portion 2231a removes its downward pressure on the first pressing member 221. Referring to Figure 10, the first pressing member 221 moves upward under the elastic restoring force of the elastic member 222, thereby separating the first pressing member 221 from the first sliding member 212. This cuts off the power transmission between the first sliding member 212 and the first pressing member 221.
[0068] Referring to Figures 9 or 11, in some embodiments, the first pressing member 221 includes a second wedge-shaped portion 2211 and a first protrusion 2212. The second wedge-shaped portion 2211 is opposite to the first wedge-shaped portion 2231a. The first seat 310 is provided with a through hole 311. The first protrusion 2212 is slidably engaged with the wall of the through hole 311. The end of the first protrusion 2212 facing the first power output portion 210b is used to abut against the first power output portion 210b. The sliding direction of the first protrusion 2212 is perpendicular to the sliding direction of the second pressing member 2231.
[0069] In this way, the first protrusion 2212 can slide relative to the first base 310, allowing the first protrusion 2212 and the first sliding member 212 to switch between an abutting state and a separated state. Furthermore, since the first protrusion 2212 is slidably connected to the wall of the through hole 311 in the first base 310, when the first pressing member 221 is driven by the first sliding member 212, the first pressing member 221 can drive the first base 310 of the first optical engine 300 to move in a direction perpendicular to the protrusion direction of the first protrusion 2212.
[0070] Referring to Figures 6 to 11, in some embodiments, the pressing member driving structure 223 further includes a deformable member 2232. It should be noted that the deformable member 2232 is a device capable of elastic deformation. The deformable member 2232 has a first connecting portion 2232a, a second connecting portion 2232b, and a third connecting portion 2232c arranged sequentially. The first connecting portion 2232a and the third connecting portion 2232c are respectively connected to the first base 310, and the second connecting portion 2232b is connected to the second pressing member 2231.
[0071] When the second pressing member 2231 is in the first position, the second connecting portion 2232b is located on the side of the line connecting the first connecting portion 2232a and the third connecting portion 2232c facing the first pressing member 221. When the second pressing member 2231 is in the second position, the second connecting portion 2232b is located on the side of the line connecting the first connecting portion 2232a and the third connecting portion 2232c away from the first pressing member 221.
[0072] Taking Figure 9 as an example, and referring to Figures 6 and 7, when the second pressing member 2231 moves from left to right to the first position, the second connecting part 2232b is located to the right of the line connecting the first connecting part 2232a and the third connecting part 2232c. In this way, the deformable member 2232 can be used to keep the second pressing member 2231 in the first position. Consequently, the clutch mechanism 220 can remain in the power transmission state without the application of external force.
[0073] Taking Figure 11 as an example, and referring to Figures 6 and 7, when the second pressing member 2231 moves from right to left to the second position, the second connecting part 2232b is located to the left of the line connecting the first connecting part 2232a and the third connecting part 2232c. In this way, the deformable member 2232 can be used to keep the second pressing member 2231 in the second position. Consequently, the clutch mechanism 220 can be kept in the power-off state without the application of external force.
[0074] Referring to Figures 4 to 11, in some embodiments, the pressing member driving structure 223 further includes a first electromagnet 2233 and a first magnetic element 2234. One of the first electromagnet 2233 and the first magnetic element 2234 is connected to the first base 310, and the other is connected to the second pressing member 2231. The first electromagnet 2233 and the first magnetic element 2234 are arranged opposite to each other.
[0075] Exemplarily, the first electromagnet 2233 includes a first electromagnetic winding. The first electromagnet 2233 is connected to the first base 310. The first magnetic element 2234 is a first permanent magnet, and the first magnetic element 2234 is connected to the second pressing element 2231. When the magnetic poles are the same on opposite sides of the first electromagnet 2233 and the first magnetic element 2234, a repulsive force is generated between the first electromagnet 2233 and the first magnetic element 2234 to drive the second pressing element 2231 to move toward a first position. Taking Figure 9 as an example, the repulsive force generated between the first electromagnet 2233 and the first magnetic element 2234 is used to drive the second pressing element 2231 to move to the right.
[0076] When the magnetic poles of the first electromagnet 2233 and the first magnetic element 2234 are opposite on opposite sides, an attractive force is generated between the first electromagnet 2233 and the first magnetic element 2234 to drive the second pressing element 2231 to move towards the second position. Taking Figure 11 as an example, the attractive force generated between the first electromagnet 2233 and the first magnetic element 2234 is used to drive the second pressing element 2231 to move to the left.
[0077] In some embodiments, the pressing member driving structure 223 further includes a second electromagnet 2235 and a second magnetic member 2236. One of the second electromagnet 2235 and the second magnetic member 2236 is connected to the first base 310, and the other is connected to the second pressing member 2231. The second electromagnet 2235 and the second magnetic member 2236 are disposed opposite to each other.
[0078] For example, the second electromagnet 2235 includes a second electromagnetic winding. The second electromagnet 2235 is connected to the first base 310. The second magnetic element 2236 is a second permanent magnet, and the first magnetic element 2234 is connected to the second pressing element 2231.
[0079] When the second pressing member 2231 is in the first position, the distance between the second electromagnet 2235 and the second magnetic member 2236 is smaller than the distance between the first electromagnet 2233 and the first magnetic member 2234. When the second pressing member 2231 is in the second position, the distance between the first electromagnet 2233 and the first magnetic member 2234 is smaller than the distance between the second electromagnet 2235 and the second magnetic member 2236.
[0080] Taking Figure 9 as an example, when the second pressing member 2231 is in the first position, the distance between the second electromagnet 2235 and the second magnetic member 2236 is smaller than the distance between the first electromagnet 2233 and the first magnetic member 2234. Therefore, when it is necessary to drive the second pressing member 2231 to move to the left and switch to the second position, the repulsive force between the second electromagnet 2235 and the second magnetic member 2236 can be used to drive the second pressing member 2231 to move to the left.
[0081] Taking Figure 11 as an example, when the second pressing member 2231 is in the second position, the distance between the first electromagnet 2233 and the first magnetic member 2234 is smaller than the distance between the second electromagnet 2235 and the second magnetic member 2236. Therefore, when it is necessary to drive the second pressing member 2231 to move to the right and switch to the first position, the repulsive force between the first electromagnet 2233 and the first magnetic member 2234 can be used to drive the second pressing member 2231 to move to the right.
[0082] Referring to Figures 6, 7, and 9, in some embodiments, the deformable member 2232 is a torsion spring. The deformable member 2232 includes a first helical portion 22321, a second helical portion 22322, and a third helical portion 22323. The first helical portion 22321 forms a first connecting portion 2232a, the second helical portion 22322 forms a second connecting portion 2232b, and the third helical portion 22323 forms a third connecting portion 2232c.
[0083] The first seat 310 also includes a second protrusion 312 and a third protrusion 313. The second pressing member 2231 includes a fourth protrusion 2231b. A first spiral portion 22321 is sleeved on the second protrusion 312, and a third spiral portion 22323 is sleeved on the third protrusion 313. A second spiral portion 22322 is sleeved on the fourth protrusion 2231b.
[0084] It should be noted that the above embodiments are mainly described using the power distribution mechanism including a screw, a first sliding member, and a second sliding member as an example. In other embodiments, for example, the power distribution mechanism 210 may also include a gear and rack mechanism, in which the gear drives the rack to slide by rotating the gear, and then the two racks drive the first optical engine and the second optical engine to move respectively. Further, exemplarily, a clutch mechanism can be provided on the gear transmission mechanism.
[0085] To facilitate understanding of the solutions provided in the embodiments of this application by those skilled in the art, the working principle of the binocular optical device 1 is briefly described below.
[0086] After receiving the working command, the driver 100 starts working, driving the screw 211 to rotate. The screw 211 drives the first sliding member 212 and the second sliding member 213 that cooperate with it to move under the guidance of the first sliding rod 214 and the second sliding rod 215.
[0087] In the initial state, the second pressing member 2231 presses against the first pressing member 221, and the first pressing member 221 and the first sliding member 212 are in a engaged state. At this time, under the action of friction, the first sliding member 212 can drive the first pressing member 221 to move. The first pressing member 221 drives the first base 310 of the first optical engine 300 to move. Since the first base 310 is the mounting base of the first optical engine 300, the entire first optical engine 300 will move accordingly.
[0088] When a user uses the binocular optical device 1, the device drives the first slide bar 214 and the second slide bar 215 to move simultaneously based on the position of the pupil center. The movement of the first slide bar 214 and the second slide bar 215 drives the movement of the first optical engine 300 and the second optical engine 400. When the first optical engine 300 moves to a position where it is aligned with the pupil of one eye, the first optical engine 300 completes its positional movement and no further adjustment is needed.
[0089] Because the human eye is usually asymmetrical in its physiological structure, the position of the second optical engine 400 is usually somewhat off from the designated position and needs to be adjusted individually. During the individual adjustment of the position of the second optical engine 400, the connection between the first pressing member 221 and the first sliding member 212 needs to be disconnected.
[0090] Furthermore, referring to Figure 9, power can be supplied to the second electromagnet 2235, generating a repulsive force between the second electromagnet 2235 and the second magnetic component 2236, thereby driving the second pressing component 2231 to move to the left. When the second pressing component 2231 is subjected to force, the deformable component 2232 deforms. With the second connecting portion 2232b positioned to the left of the line connecting the first connecting portion 2232a and the third connecting portion 2232c, the deformable component 2232 also drives the second pressing component 2231 to move to the left.
[0091] Referring to Figures 10 and 11, the pressure of the second pressing member 2231 on the first pressing member 221 decreases, and the first pressing member 221 moves upward under the elastic restoring force of the elastic member 222. The first pressing member 221 and the first sliding member 212 separate. That is, the clutch mechanism 220 is in the power-off state, and the transmission assembly 200 is in the second transmission state. In this state, the driver 100 will not drive the first optical engine 300 to move; the driver 100 can only drive the second optical engine 400 to move, thus allowing the second optical engine 400 to be adjusted to a position opposite to the pupil of the other eye. At this point, the first optical engine 300 and the second optical engine 400 are respectively opposite to the pupils of both eyes.
[0092] This application provides a control method for a binocular optical device, applicable to any binocular optical device 1 provided in this application.
[0093] Referring to Figure 12, the control method of the binocular optical device provided in this application embodiment includes: step 1010, controlling the driver to work, driving the first optical engine and the second optical engine to move synchronously until the second optical engine is opposite to the pupil of one eye; step 1020, supplying power to the second electromagnet so that the second pressing member moves away from the first pressing member, the first pressing member moves away from the first sliding member, and the first pressing member separates from the first sliding member; step 1030, controlling the driver to continue working, driving the first optical engine to move until the first optical engine is opposite to the pupil of the other eye.
