[0027] The following detailed description refers to the drawings that form a part of this specification. The illustrative embodiments mentioned in the specification and the drawings are for illustrative purposes only and are not intended to limit the scope of protection of the present application. Under the enlightenment of the present application, those skilled in the art will understand that many other embodiments can be adopted, and various changes can be made to the described embodiments without departing from the main purpose and scope of protection of the utility model. It should be understood that the various aspects of the present application described and illustrated herein can be arranged, replaced, combined, separated and designed according to many different configurations, and these different configurations are within the scope of protection of the present application.

[0029] See also Figures 1 to 4 The eye-use electronic device may include a host 10 and an eye mask assembly 20. The host 10 may be equipped with a light source assembly for adjusting vision or relieving visual fatigue, a controller 11 connected to the light source assembly, and other electronic components. A battery 12 may also be provided in the host 10. The eye mask assembly 20 is detachably connected to the host 10. Figure 1 and Figure 3 is a schematic diagram of the eye mask assembly 20 being installed on the host 10, Figure 2 and Figure 4 It is a schematic diagram of the eye mask assembly 20 and the host 10 when they are separated.

[0030] The eye mask assembly 20 and the host 10 can be connected by snapping, and magnets 21 can be provided at corresponding positions of the housing 100 of the host 10 and the eye mask assembly 20. When the eye mask assembly 20 is snapped onto the host 10, the corresponding magnets 21 attract each other, which can improve the stability of the connection and facilitate the replacement and use of the eye mask assembly 20.

[0031] As follows, the host 10 of the ophthalmic electronic device provided by the present invention is described in detail.

[0032] See also Figure 3 to Figure 4 In one embodiment of the present invention, the eye-use electronic device includes a housing 100 , and two groups of light source components corresponding to two light outlets 131 may be arranged in the housing 100 .

[0033] In this embodiment, the lights of the two light source assemblies will not intersect each other, and the lights of the two light source assemblies are independently transmitted through the corresponding light outlets 131. In a specific embodiment of the utility model, the eye-use electronic device includes a lens barrel assembly, which includes two lens barrels 130, and the lens barrels 130 may have a light outlet 131, and a light source assembly is disposed in each lens barrel 130. The lens barrel assembly can be installed in the housing 100. During use by the user, the light of the light source assembly is transmitted through the light outlet 131 and enters the user's eye.

[0034] In this embodiment, the light source assembly may include at least one of a combined image light source 220 , a pupil laser light source 210 , and a multi-spectrum light source 230 .

[0035] In a specific embodiment provided by the present invention, the ophthalmic electronic device is a multifunctional ophthalmic electronic device, and the light source assembly includes a combined image light source 220, a pupil laser light source 210 and a multi-spectrum light source 230.

[0036] In this embodiment, the ophthalmic electronic device further comprises a functional mode switch, which can be used to selectively turn on one light source or turn on and off at least part of at least two light sources in sequence according to a predetermined order.

[0037] Among them, there can be multiple combined image light sources 220, and two groups of symmetrical light-emitting elements can be arranged in the two lens barrels 130. When the user wears the eye-use electronic device, the user can be used as a reference, and the side close to the user is the front, and the side away from the user is the back. At the same time, the user can be used as a reference, and the upper side of the user is the top, and the lower side of the user is the bottom. The combined image light source in each lens barrel 130 can include multiple light-emitting elements arranged in sequence from top to bottom or from front to back.

[0038] In the specific implementation mode provided by the utility model, the light-emitting parts in the lens barrel 130 are arranged in sequence from front to back, and the two light-emitting parts located on the same horizontal line in the two lens barrels 130 can be considered as a light-emitting part group. During use, different light-emitting part groups are opened and closed in sequence according to a predetermined order. When the spacing between the two light-emitting parts of a light-emitting part group is the same as or close to the pupil distance, the two eyes can recognize the two light sources as a light source point, that is, the binocular image is achieved, and when the spacing between the two light-emitting parts of a light-emitting part group does not match the pupil distance, the light source points seen by the eyes are two scattered light source points, and are in a non-image state. In the image mode, the user observes the light source points in the lens barrel 130, and by controlling the opening and closing of the light-emitting parts, the image and non-image training can be performed, which can exercise the ciliary muscle, relieve visual fatigue, prevent myopia, and treat pseudomyopia.

[0039] The pupil laser light source 210 is used to illuminate the pupil. The pupil laser light source 210 can be a 650nm red light. By irradiating the pupil with 650nm red light, the development of cone cells is stimulated, which can be used to treat amblyopia. At the same time, it can promote blood circulation and dopamine secretion, improve scleral hypoxia, and delay the development of myopia.

[0040] The multi-spectrum light source 230 may include a color light emitting element that emits at least two different colors of light. Preferably, the multi-spectrum light source 230 includes a color light emitting element that emits three different colors of light.

[0041] In a specific embodiment, the multi-spectral light source 230 includes a color light emitting component that emits three different colors of red, green, and blue. During use, the red, green, and blue lights flash alternately, which can stimulate cone cells and promote visual development. Specifically, it can be used to treat refractive errors, anisometropia, and strabismic amblyopia.

[0042] See also Figure 5 The ophthalmic electronic device further comprises a driving assembly 500, which comprises two driving motors 510, which are fixedly mounted in the housing 100 and are respectively connected to the two lens barrels 130. In this embodiment, the driving assembly 500 further comprises a screw transmission mechanism for connecting the driving motors 510 and the lens barrels 130.

[0043] The screw transmission mechanism also has two groups. Connecting the drive motor 510 and the lens barrel 130 through the screw transmission mechanism can reduce space occupation and facilitate miniaturization design.

[0044] In this embodiment, a camera element 136 may be provided in the housing 100, and the camera element 136 may be used to capture an eye image to obtain the pupil distance. The camera element 136 may be an infrared camera element, and a fill light 137 may be provided in the housing 100, and the fill light 137 may be used to fill light for the camera element 136 to capture a clear eye image.

[0045] In a specific implementation, the imaging element 136 and the fill light 137 may be provided in two groups, and may be respectively provided in two lens barrels 130 .

[0046] The controller 11 can calculate the pupil distance according to the eye image captured by the imaging element 136 , and control the two driving motors 510 to operate respectively according to the pupil distance to independently drive the two lens barrels 130 to move.

[0047] By independently driving the two lens barrels 130 to move through the two driving motors 510 , the lens barrels 130 can be quickly moved to a proper position to achieve image combination with both eyes.

[0048] For further information, see Figures 5 to 9 In one embodiment of the utility model, the screw transmission mechanism may include a screw 521 and a transmission member 522. The screw 521 may be connected to the output shaft of the driving motor 510, and the transmission member 522 may have a threaded portion that cooperates with the screw 521. The driving motor 510 may drive the screw 521 to rotate and drive the transmission member 522 to move in the first direction x1 along the axial direction of the screw 521 when the driving motor 510 rotates forward. The driving motor 510 may drive the screw 521 to rotate and drive the transmission member 522 to move in a second direction opposite to the first direction x1 when the driving motor 510 rotates reversely. The transmission member 522 and the lens barrel 130 are relatively fixed along the axial direction of the screw 521, so that the transmission member 522 may drive the lens barrel 130 to move synchronously along the axial direction of the screw 521 when the transmission member 522 moves along the axial direction of the screw 521. In this way, the lens barrel 130 may be moved quickly and accurately.

[0049] Furthermore, in this embodiment, the screw transmission mechanism further includes a connecting member 523 fixed to the lens barrel 130 , the transmission member 522 is at least partially inserted into the connecting member 523 , and the transmission member 522 and the connecting member 523 are relatively fixedly connected along the axial direction of the screw 521 .

[0050] The connecting member 523 and the transmission member 522 can be relatively fixed in the axial direction, and can be relatively movable in other directions, such as the up and down directions perpendicular to the axial direction. The plug-in direction of the transmission member 522 and the connecting member 523 can be parallel to the up and down directions. In this way, during the installation and manufacturing process, the transmission member 522 and the connecting member 523 can be quickly and conveniently connected.

[0051] Furthermore, in this embodiment, the eye-use electronic device further comprises a sliding rod 524, which is fixedly connected to the driving motor 510. The sliding rod 524 can be arranged in parallel with the screw rod 521, and the transmission member 522 is further provided with a through hole, and the transmission member 522 can be slidably connected to the sliding rod 524 through the through hole.

[0052] The sliding rod 524 can pass through the through hole of the transmission member 522, and the sliding rod 524 can play an auxiliary supporting role, thereby improving the connection stability of the overall structure. The transmission member 522 is slidably connected to the sliding rod 524 through the through hole, ensuring that the transmission member 522 has additional support and guidance when the screw rod 521 moves axially, preventing the transmission member 522 from deviating during the movement.

[0053] In this embodiment, a drive motor 510 is installed at one end of the screw rod 521 and the sliding rod 524, and a shaft seal 525 is installed at the other end. The shaft seal 525 can be connected to the housing 100, so that the screw rod 521 and the sliding rod 524 are stably connected to the housing, ensuring the stable transmission of the screw rod 521 and improving the durability and reliability of the device.

[0054] The transmission member 522 is disposed below the lens barrel 130. A threaded portion is disposed at one end of the transmission member 522, and a transmission plate 5221 is disposed at the other end. A through hole for the sliding rod 524 to pass through is provided in the transmission plate 5221. The connecting member 523 is provided with a connecting groove 5231. The transmission plate 5221 is at least partially inserted into the connecting groove 5231. The connecting groove 5231 includes two groove walls 5232 spaced apart along the axial direction of the sliding rod 524. The connecting groove 5231 is open toward the lower part and toward the sliding rod 524.

[0055] In this embodiment, the transmission member 522 is divided into two parts, one part is provided with a threaded portion directly connected to the screw rod 521, and the other part is provided with a transmission plate 5221 connected to the sliding rod 524. During the installation and manufacturing process, the shaft seal 525, the screw rod 521, the sliding rod 524, the transmission member 522 and the drive motor 510 can be connected first, and then the drive motor 510 can be fixed to the housing 100. After the connecting member 523 is fixed to the lens barrel 130, the connecting member 523 and the lens barrel 130 can be directly placed on the transmission member 522, and the transmission plate 5221 can be directly inserted into the connecting groove 5231 of the connecting member 523, so that the connecting member 523 and the transmission member 522 are relatively fixed in the axial direction, and the overall installation process is simple and convenient.

[0056] Further, in one embodiment of the utility model, the connecting member 523 is further provided with a rod groove 5235, and at least a portion of the sliding rod 524 is placed in the rod groove 5235. The rod groove 5235 may also have an opening facing downward.

[0058] Specifically, the connecting member 523 has three adjacent connecting plates 5237, forming two adjacent connecting grooves 5231, and the two outermost connecting plates 5237 are provided with rod grooves 5235. After assembly, the connecting member 523 is directly supported on the sliding rod 524 and is axially relatively fixedly connected to the transmission member 522.

[0059] During the installation process, the sliding rod 524 can be directly inserted into the rod groove 5235, so that the connecting member 523 can be supported by the sliding rod 524 at the same time, further improving the stability of the overall structure.

[0060] Further, the eye-use electronic device further comprises a support rod 526, the support rod 526 is fixed to the housing 100, the support rod 526 is arranged parallel to the sliding rod 524, and the connecting member 523 is slidably connected to the support rod 526. The support rod 526 can simultaneously connect the connecting members 523 of two lens barrels 130. The support rod 526 may include two, which are respectively arranged at the front end and the rear end of the lens barrel 130.

[0061] The support rod 526 is used to further support the lens barrel 130 so as to stably connect the lens barrel 130 to the housing 100. The support rod 526 is directly connected to the connecting member 523 and the connecting members 523 of the two lens barrels 130 are connected in series, so as to support and guide the movement of the lens barrel 130.

[0062] See also Fig. 9 The ophthalmic electronic device may include a first circuit board 134 , and the first circuit board 134 may be mounted on the rear end of the housing 100 . The ophthalmic electronic device may further include a second circuit board 135 .

[0063] In the axial direction X2 of the lens barrel 130 , the lens barrel 130 may include a front end where the light outlet 131 is disposed and a rear end opposite to the front end. The first circuit board 134 may be disposed at the rear end of the lens barrel 130 , and the second circuit board 135 may be disposed on the circumferential wall 132 of the lens barrel 130 .

[0064] The first circuit board 134 may be placed inside the lens barrel 130. The rear end of the lens barrel 130 may be open to facilitate installation of the first circuit board 134. When the first circuit board 134 is installed at the rear end of the lens barrel 130, the electrical components installed on the first circuit board 134 are directly placed inside the lens barrel 130.

[0065] The second circuit board 135 may be disposed outside the lens barrel 130. The second circuit board 135 may be disposed outside the circumferential wall 132 of the lens barrel 130 and placed at the lower portion of the lens barrel 130. The second circuit board 135 may be fixed by a connector 523.

[0066] The circumferential wall 132 of the lens barrel 130 may be provided with a through hole 133, and the light emitting element in the light source assembly may be mounted on the second circuit board 135 and extend into the interior of the lens barrel 130 through the through hole 133. This arrangement facilitates the installation of the first circuit board 134 and the second circuit board 135, and the through hole 133 on the circumferential wall 132 of the lens barrel 130 cooperates with the light source to achieve a certain positioning of the second circuit board 135, which facilitates the installation of the second circuit board 135.

[0067] In this embodiment, the first circuit board 134 and the second circuit board 135 can be electrically connected. The rear end of the second circuit board 135 can have an electrical connection portion 1351, and the first circuit board 134 can have a plug portion 1341 that matches the electrical connection portion 1351. The electrical connection portion 1351 can be inserted into the plug portion 1341 to electrically connect the first circuit board 134 and the second circuit board 135. In this way, there is no need to connect through wires, and the connection can be made directly during the installation process, which is convenient for the installation and manufacturing process.

[0068] The first circuit board 134 and the second circuit board 135 can be arranged at an angle. The circumferential wall 132 of the lens barrel 130 can be arranged at an angle, and when the second circuit board 135 is attached to the circumferential wall 132 of the lens barrel 130, the first circuit board 134 and the second circuit board 135 can be at an acute angle. Such an arrangement can reduce the size of the entire device in the length direction, which is conducive to miniaturization design.

[0069] In one embodiment, the light source assembly includes a pupil laser light source 210. The pupil laser light source 210 is mounted on the first circuit board 134. The first circuit board 134 is disposed at the rear end corresponding to the light outlet 131, that is, the pupil laser light source 210 is directly opposite to the light outlet 131, and its light can be directly transmitted to the pupil through the light outlet 131, so that the treatment effect is better.

[0070] The multi-spectrum light source 230 is mounted on the first circuit board 134. The ophthalmic electronic device further includes a light homogenizer 138, and the light of the multi-spectrum light source 230 can pass through the light homogenizer 138 and then be transmitted through the light outlet 131. The light homogenizer 138 can be mounted on the front side of the first circuit board 134 and cover the multi-spectrum light source 230. By arranging the light homogenizer 138 on the front side of the multi-spectrum light source 230, it can be ensured that the light of the multi-spectrum light source 230 has a uniform light visual sense after being emitted, providing a better user experience.

[0071] The first circuit board 134 may also be installed with other electrical components. Specifically, the camera element 136 may be installed on the first circuit board 134. The fill light 137 may also be installed on the first circuit board 134. It can be understood that the camera element 136 and the fill light 137 are arranged opposite to the light outlet 131. During use, the light outlet 131 is opposite to the user's eyes, and the camera element 136 can clearly capture the user's eye image through the light outlet 131.

[0072] See also Figures 10 to 12 Each group of multi-spectrum light sources 230 includes a color light emitting element that emits three colors of light. The fill light 137, the imaging element 136 and the multi-spectrum light source 230 are arranged around the pupil laser light source 210. The color light emitting elements are arranged in a triangle.

[0073] The light diffuser 138 may be provided with a through hole corresponding to the pupil laser light source 210, and the light of the pupil laser light source 210 may be directly transmitted without passing through the light diffuser 138. The above arrangement facilitates the provision of the light diffuser 138, and different electrical components can achieve good effects.

[0074] The combined image light source 220 can be installed on the second circuit board 135. Several light-emitting components of the combined image light source 220 can be tilted along the length direction of the second circuit board 135. The arrangement direction of the light-emitting components of the two combined image light sources 220 can be in an eight-shaped shape.

[0075] Further, see again Figure 3 , Figure 4 In one embodiment of the present invention, the light source assembly may further include a periorbital light source 240 for irradiating the periorbital area. The periorbital light source 240 is disposed outside the lens barrel 130 and does not move with the lens barrel.

[0076] The periocular light source 240 can be a 650nm laser light source. During use by the user, the light of the periocular light source 240 only illuminates the periocular area and does not enter the user's eyes. By stimulating the periocular area of ​​the user through the periocular light source 240, the blood circulation around the eye can be improved, thereby improving visual fatigue. The eye-use electronic device can also isolate the periocular light source 240 by setting a shading element to prevent the light of the periocular light source 240 from entering the user's eyes during use, thereby improving the safety of use.

[0077] The eye-viewing electronic device further includes a sensor 420 , which can be used to detect an approaching signal or a moving-away signal.

[0078] The sensor 420 is used to detect the approach and distance of the user. When the sensor 420 detects that the user is within a preset distance, a proximity signal may be detected. When the sensor 420 detects that the distance between the user and the sensor 420 is greater than a preset distance, a distance signal may be detected. The preset distance may be 0 or close to 0, or greater than 0.

[0079] In an embodiment of the present invention, the sensor 420 may be a contact sensor, the approach signal may be a contact signal, and the distance signal may be a non-contact signal.

[0080] The sensor 420 may be a capacitive sensor. When the user approaches the sensor 420, the capacitance of the sensor 420 changes, so that the approach and distance of the user can be determined based on the change in capacitance.

[0081] According to the signal detected by the sensor 420, electrical components such as the light source assembly, the camera element 136, and the fill light 137 can be automatically controlled to improve the overall intelligence level of the eye-use electronic device and reduce the operations required by the user.

[0082] In this embodiment, when the sensor 420 detects a proximity signal, the imaging element 136 is turned on, and when the sensor 420 detects a distance signal, the imaging element 136 is turned off.

[0083] The controller 11 can also control the light source to turn off or reduce the power when the sensor 420 detects a distance signal, thereby preventing the light source from accidentally hurting the user's eyes. At the same time, it can save energy and increase the overall standby time.

[0084] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
