Description

Technical Field

[0001] The present application relates to the field of optical technology, and in particular to a near-eye display device and a wearable device. Background Art

[0002] Near-eye display (NED) is a technology that uses a display device placed within the non-clear viewing distance of the human eye to render light field information to the human eye, thereby reconstructing a virtual scene in front of the human eye. Among them, the NED device can create a virtual image in the field of view of one eye or two eyes. The NED device is usually used in conjunction with wearable devices such as glasses.

[0003] The near-eye display device requires a power module to power it. The external power module is not easy to install and will increase the manufacturing cost of the wearable device. Taking optical waveguide smart glasses as an example, the entire optical machine and power module are mostly designed on the temples, and the optical path is converted to the lens through the temples. When the user wears the temples, the temples are attached to the brain or temples. The heat generated by the operation of the optical machine and the power module needs to be dissipated through a heat sink (such as a copper sheet, etc.), which further increases the weight. In order to balance the weight of the left and right temples, it is further necessary to add metal counterweights, etc., which ultimately results in the weight of the near-eye display device being heavier than ordinary glasses. Therefore, it also creates a burden for long-term wear and causes discomfort to the user. Utility Model Content

[0004] The purpose of this application is to overcome the defects of the prior art and provide a near-eye display device and a wearable device to solve the problems in the prior art.

[0005] To solve the above problems, the embodiments of the present application provide a near-eye display device in a first aspect, comprising a housing, a power module and a power module, wherein the power module and the power module are both arranged inside the housing, and the power module is electrically connected to the power module; the power module comprises a display module and a circuit board module which are electrically connected, and the circuit board module is electrically connected to the power module;

[0006] Among them, the display module and the circuit board module are stacked, the power supply module is arranged on the periphery of the display module and the circuit board module, the height of the power supply module at least partially overlaps with the height between the display module and the circuit board module, and the display module is configured to generate light; the light is not blocked by the power supply module.

[0007] The second aspect of an embodiment of the present application provides a wearable device, including a wearing piece and a near-eye display device as described above, wherein the wearing piece is used to be worn on the head of a user; wherein the near-eye display device is detachably connected to the wearing piece.

[0008] The beneficial effects of this application include:

[0009] In the present application, the display module and the circuit board module of the power module are stacked, the power module is arranged on the periphery of the display module and the circuit board module, and the height of the power module at least partially overlaps with the height between the display module and the circuit board module. This arrangement enables the power module and the display module to be located in the same housing, which is not the housing of the temple of the wearer's temple, so there is no need to put the electrical components on the temple. On the other hand, by reasonably arranging the positions of the power module and the power module, the space utilization rate is improved, the height of the housing can be effectively reduced, and the problem of increased housing height caused by the stacking of the power module and the power module is avoided.

[0010] The near-eye display device can effectively avoid placing the power module on the wearer's temples, and the above-mentioned arrangement can effectively reduce the height of the shell, thereby reducing the total weight of the wearable device (such as glasses, etc.) equipped with the near-eye display device.

[0029] Embodiment 1

[0030] See also Figure 1-Figure 4 In this embodiment, a near-eye display device 10 is provided, including a housing 100, a power module 200 and a power module 300. The power module 200 and the power module 300 are both arranged inside the housing 100, and the power module 200 is electrically connected to the power module 300. The power module 200 includes a display module 210 and a circuit board module 220 that are electrically connected, and the circuit board module 220 is electrically connected to the power module 300.

[0031] The display module 210 and the circuit board module 220 are stacked, the power module 300 is arranged at the periphery of the display module 210 and the circuit board module 220, the height of the power module 300 at least partially overlaps the height between the display module 210 and the circuit board module 220, and the display module 210 is configured to generate light, wherein the light is not blocked by the power module 300.

[0032] Specifically, Figure 5 As shown, the housing 100 is provided with a first installation cavity 110 and a second installation cavity 120 , and the second installation cavity 120 is arranged around the first installation cavity 110 . The power module 200 is installed in the first installation cavity 110 , and the power module 300 is installed in the second installation cavity 120 .

[0033] The central axes of the first installation cavity 110 and the second installation cavity 120 are substantially parallel to the height direction of the housing 100. For example, in some embodiments, the first installation cavity 110 and the second installation cavity 120 may be coaxially arranged, that is, the central axes of the two are collinear.

[0034] Reference Figure 4 and Figure 5 , the height direction of the housing 100 is parallel to the direction indicated by the arrow x, and the dot-dash line L represents the central axis of the first installation cavity 110 and the second installation cavity 120. In order to intuitively see the first installation cavity 110 and the second installation cavity 120, the figure uses a dotted line to illustrate the boundary between the first installation cavity 110 and the second installation cavity 120. It should be noted that in the actual product, the dotted line does not exist.

[0035] Reference Figure 3In this embodiment, the power module 300 is a complete whole. The power module 300 is formed with a central accommodating cavity 310, and the display module 210 and the circuit board module 220 are located at the center of the central accommodating cavity 310. The axial direction of the display module 210 is substantially parallel to the height direction of the power module 300, thereby achieving center alignment and facilitating assembly. The power module 300 includes an integral battery and surrounds the periphery of the display module 210 and the circuit board module 220.

[0036] The cross-sectional shape of the outer contour of the central accommodating cavity 310 includes an arc or a ring, and the cross-sectional shape of the power module 300 is perpendicular to the height direction of the power module 300. The display module 210 and the circuit board module 220 are sequentially arranged along the height direction of the power module 300.

[0037] When installing components such as the power module 200 and the power module 300, the distance between adjacent components should be as close as possible, while ensuring the normal operation of each component and preventing abnormalities such as short circuits. This can maximize the use of space and reduce the manufacturing size of the shell 100 to a certain extent.

[0038] By installing the power module 200 in the first installation cavity 110 and the power module 300 in the second installation cavity 120, the positions of the power module 200 and the power module 300 are reasonably arranged, and the height of the housing 100 is effectively reduced, avoiding the problem of the height of the housing 100 being increased due to the stacking of the power module 300 and the power module. The height of the near-eye display device 10 is equal to the height of the housing 100.

[0039] like Figure 3 As shown, in this embodiment, the power module 200 includes a display module 210 and a circuit board module 220 that are electrically connected. The cross-sectional shape of the power module 300 is an arc, and the cross-sectional shape of the power module 300 is a cross-sectional shape perpendicular to the height direction of the power module 300. Among them, the display module 210 and the circuit board module 220 are arranged in sequence along the height direction of the power module 300. Figure 4 and Figure 5 The height directions of the power module 300 and the power module 200 are parallel to the height direction of the housing 100 , and are both parallel to the direction indicated by the arrow x.

[0040] In some other embodiments, the cross-sectional shape of the power module 300 may be annular.

[0041] like Figure 6As shown, the display module 210 includes a micro display 211. The micro display 211 can be one of Micro-LED (Micro Light-Emitting Diode), uLED (Micro Light Emitting Diode), Micro-oled (Micro Organic Light-Emitting Diode), LCoS (Liquid Crystal On Silicon), LCD (Liquid Crystal Display), DMD (Digital Micromirror Device), DLP (Digital Light Processing) or LBS (Laser Beam Scanning), or any combination of these technologies.

[0042] Reference Figure 4 , the size of the column marked with y in the figure represents the thickness of the power module 300. In some embodiments, the capacity of the power module 300 can be increased by increasing the thickness of the power module 300, thereby improving the battery life of the near-eye display device 10.

[0043] like Figure 4 As shown, the power module 300 includes an upper end face and a lower end face disposed at both ends of its height direction, and the power module 200 is at least partially located between the upper end face and the lower end face. Such a structure can improve the utilization rate of the space enclosed by the power module 300 and ensure that the power module 300 has a certain height to ensure its own capacity. If the power module 200 is not located in the space enclosed by the power module 300, then the height of the housing 100 needs to be increased to fully accommodate the power module 200 and the power module 300.

[0044] Compared with the button battery arrangement of some prior arts, in this embodiment, the power module 200 is entirely located between the upper end surface and the lower end surface. This means that the height of the power module 300 is not less than the height of the power module 200. Under the condition that the height of the housing 100 is constant, such a structural arrangement can effectively increase the height of the power module 300 to improve the capacity of the power module 300, and at the same time, it also realizes the reasonable use of the internal space of the housing 100.

[0045] The circuit board module 220 includes a power supply module and a control module. The power supply module is electrically connected to the control module. The power supply module may include electronic components such as resistors and capacitors. The power supply module obtains the electric energy transmitted by the power module 300 and transmits it to the control module and other electrical devices; the control module may include a microprocessor, etc. It should be noted that the attached figure is only a schematic diagram, and electronic components such as resistors, capacitors, and microprocessors are not marked in the figure.

[0046] In this embodiment, the power supply module is integrated on the first circuit board 221, and the control module is integrated on the second circuit board 222. When the number of electronic components is too large, such a setting can avoid the electronic components from being too densely distributed, thereby reducing the difficulty of processing and manufacturing. The first circuit board 221 is provided with a positive terminal and a negative terminal, wherein the positive terminal can be electrically connected to the positive pole of the power module 300 through a wire, and the negative terminal can be electrically connected to the negative pole of the power module 300 through a wire.

[0047] In some other embodiments, the power supply module and the control module may be integrated on the same circuit board.

[0048] Reference Figure 3 and Figure 4 , an optical module 230 is provided on the light-emitting side of the display module 210, the housing 100 includes a light-transmitting portion 130, and the optical module 230 is located between the light-transmitting portion 130 and the display module 210. The optical module 230 allows light to pass through, and can be made of transparent glass or resin or other materials. In some embodiments, the optical module 230 includes a lens, which can change the propagation direction of light, so that the human eye can clearly see the light information such as the picture or video displayed by the display module 210.

[0049] The outer surface of the light-transmitting portion 130 is a plane or a curved surface, wherein the outer surface of the light-transmitting portion 130 is a surface facing away from the optical module 230 . Figure 4 In FIG. 1 , the portion indicated by arrow a represents the outer surface of the light-transmitting portion 130 .

[0050] When the outer surface of the optical module 230 is a curved surface, different curvatures can be set to adapt to different degrees of vision, thereby meeting the needs of myopic users.

[0051] like Figure 3 and Figure 4 As shown, a fixing bracket 240 is disposed on the display module 210. The fixing bracket 240 can realize the fixing between the display module 210 and the optical module 230.

[0052] like Figure 7 and Figure 8As shown, the fixing bracket 240 includes a first connecting portion 241 and a second connecting portion 242. The first connecting portion 241 is provided with a first mounting portion 2411, and the second connecting portion 242 is provided with a second mounting portion 2421. The first mounting portion 2411 is a hole structure or a slot structure, and the second mounting portion 2421 is a hole structure or a slot structure. The first mounting portion 2411 and the second mounting portion 2421 are interconnected. In this embodiment, the first mounting portion 2411 adopts a slot structure, and the second mounting portion 2421 adopts a hole structure.

[0053] The micro display 211 of the display module 210 is installed in the first installation portion 2411. The micro display 211 can be inserted into the first installation portion 2411.

[0054] The optical module 230 is partially installed in the second installation portion 2421 .

[0055] The micro display 211 of the display module 210 is installed in the inner cavity of the first connecting portion 241 , and the optical module 230 is at least partially installed in the inner cavity of the second connecting portion 242 .

[0056] like Fig. 9 As shown, in this embodiment, the optical module 230 includes a first component 231 and a second component 232, wherein the first component 231 and the second component 232 are both cylindrical and coaxially arranged, the outer diameter of the first component 231 is greater than the outer diameter of the second component 232, and the outer diameter of the first component 231 is greater than the inner diameter of the second mounting portion 2421. During assembly, the second component 232 can be inserted into the second mounting portion 2421, wherein, since the outer diameter of the first component 231 is greater than the inner diameter of the second mounting portion 2421, the first component 231 cannot be inserted into the second mounting portion 2421. When the second component 232 is completely inserted into the second mounting portion 2421, the second connecting portion 242 and the first component 231 are in contact with each other, thereby realizing the installation and positioning of the optical module 230 on the fixing bracket 240.

[0057] The fixture bracket can be made of opaque material, thereby preventing light leakage and the like from occurring.

[0058] like Figure 3 and Figure 4 As shown, in this embodiment, the power module 200 further includes a third circuit board 250, which is located on a side of the display module 210 away from the circuit board module 220. For example, the third circuit board 250 is fixedly sleeved on the second connecting portion 242. Compared with the display module 210, the third circuit board 250 is closer to the light-transmitting portion 130. The third circuit board 250 is electrically connected to the control module.

[0059] The third circuit board 250 is provided with one or more of a sensor module, a light emitting element, a sound receiving unit or a sound emitting unit, wherein the sensor module includes a light sensor and / or a posture sensor.

[0060] In some embodiments, a light sensor is disposed on the third circuit board 250, wherein the light sensor is disposed toward the light-transmitting portion 130. The light sensor is used to detect ambient light from the outside, wherein the light sensor sends the detected signal to the control module, and the control module adaptively adjusts the display brightness of the micro display 211. For example, when the ambient brightness becomes brighter, the brightness of the micro display 211 is increased; when the ambient brightness becomes weaker, the brightness of the micro display 211 is reduced.

[0061] In some embodiments, a posture sensor is disposed on the third circuit board 250 , wherein the posture sensor may include an IMU sensor (Inertial Measurement Unit), which may be configured to obtain the motion state of the near-eye display device 10 .

[0062] In some embodiments, a light-emitting element is provided on the third circuit board 250, wherein the light-emitting element may include an LED lamp bead. The light-emitting element may be used for reminders or warnings. For example, when the power module 300 is low on power, the light-emitting element emits red light; when a message is received, the light-emitting element emits blue light.

[0063] In some embodiments, a sound receiving unit and a sound emitting unit are provided on the third circuit board 250, and both the sound receiving unit and the sound emitting unit are provided toward the light-transmitting portion 130. The sound receiving unit may include a microphone, and the sound emitting unit may include a speaker. The microphone may be used to receive a user's voice signal, and the speaker may be used to play a sound signal. The sound signal played by the speaker may come from the video, audio, etc. played by the micro display 211, or the user's instant messaging voice, etc.

[0064] like Figure 5 As shown, the housing 100 includes a surrounding portion 140, which is arranged around the circumference of the light-transmitting portion 130. One end of the surrounding portion 140 is connected to the light-transmitting portion 130, and the other end is provided with an opening structure 141. The power module 200 and the power module 300 are installed inside the housing 100 through the opening structure 141.

[0065] In this embodiment, a light-proof sleeve 150 is disposed between the surrounding portion 140 and the power module 300, wherein the sleeve 150 is disposed around the second installation cavity 120, and the display module 210 is located inside the sleeve 150. The surrounding portion 140 and the light-transmitting portion 130 may be an integrated structure, both of which are light-transmitting, and by disposing the light-proof sleeve 150 between the surrounding portion 140 and the power module 300, it is possible to prevent external light from interfering with the optical signal emitted by the microdisplay 211, and to prevent the optical signal emitted by the microdisplay 211 from leaking light, etc. The sleeve 150 may be made of a light-proof resin or metal.

[0066] In some embodiments, the surrounding portion 140 is opaque, thereby avoiding interference from external light or light leakage. Since the surrounding portion 140 is opaque, there is no need to additionally provide the sleeve 150, thereby simplifying the structure. The surrounding portion 140 can be made of an opaque material, or an opaque film or coating can be provided on the surface of the surrounding portion 140.

[0067] like Figure 3 and Figure 4 As shown, in the present embodiment, a cover body 160 is provided on the shell 100, and the cover body 160 is used to close the opening structure 141. The cover body 160 can be installed in the opening structure 141 by means of threaded connection, snap-fit, interference fit, etc. A groove 161 is provided on the cover body 160, and an attraction member 162 that can be attracted by a magnet is installed in the groove 161, and the attraction member 162 can be magnetized or has magnetic properties. The attraction member 162 can be made of magnetizable ferritic stainless steel or the like, or the attraction member 162 can be directly made of a magnet. The attraction member 162 can have a sheet structure, and the attraction member 162 can be fixed in the groove 161 by means of bonding or the like. Among them, the attraction member 162 is configured to be magnetically attracted to each other with an external attraction member so as to assemble the near-eye display device 10 to the wearable member 400 (such as Fig.11 In the exemplary wearable device embodiment description, the wearable component 400 may be a lens or a frame, wherein the external attraction component material may be the same as the attraction component 162, and the two may be magnetically attracted to each other so as to be clamped and fixed on the wearable component 400, such as a lens or a frame.

[0068] In other embodiments, the cover 160 can be magnetized, so there is no need to additionally provide the attracting member 162, thereby simplifying the structure. The cover 160 can be made of magnetizable ferrite stainless steel, etc., that is, the cover can be directly magnetically attracted to the external attracting member.

[0069] The wearing member 400 may be provided with an assembly portion, which includes a magnet. When the near-eye display device 10 is installed, the cover 160 is attached to the assembly portion, wherein the near-eye display device 10 can be fixed on the wearing member 400 under the action of the magnetic field force.

[0070] like Figure 3 and Fig.10 As shown, in this embodiment, the near-eye display device also includes an antenna module 260, which is electrically connected to the circuit board module 220. The antenna module 260 is arranged along the height direction of the power module 300 and is located at the edge of the circuit board module 220. The extension direction of the antenna module 260 is parallel to the height direction of the power module 300.

[0071] Specifically, the antenna module 260 may be disposed on the outer periphery of the second circuit board 222, and the extension direction of the antenna module 260 may be perpendicular to the plane where the second circuit board 222 is located. The main body of the antenna module 260 may be a flexible circuit board. The antenna module 260 may realize wireless transmission and reception of signals, thereby enabling the near-eye display device 10 to communicate with smart devices such as mobile phones.

[0072] The antenna module 260 is arranged along the height direction of the power module 300 and is arranged on the outer periphery of the second circuit board 222, thereby preventing the power module 200 from blocking the antenna module 260 and ensuring the normal transmission and reception of wireless signals. The second circuit board 222 and the first circuit board 221 can be arranged parallel to each other, thereby effectively utilizing the internal space of the housing 100.

[0073] The power module 200 needs to be fixed, wherein the power module 200 can be fixed inside the housing 100 through a connecting structure. The connecting structure includes a groove, a step or a reinforcing rib, etc., arranged inside the housing 100. In some other embodiments, the connecting structure includes a connecting bracket, etc., fixed inside the housing 100.

[0074] Since the housing 100 is provided with a sleeve 150 in this embodiment, the connection structure can be provided on the inner wall of the sleeve 150. It should be noted that the connection structure is not shown in the figure.

[0075] like Fig.11 As shown, in the present embodiment, a wearable device is further proposed, including a wearing piece 400 and the near-eye display device 10 mentioned above, wherein the wearing piece 400 is used to be worn on the user's head; wherein the near-eye display device 10 is detachably connected to the wearing piece 400, for example, by being adsorbed on the wearing piece 400 by magnetic attraction, and the wearing piece 400 may be on a lens or a frame. In other embodiments, the near-eye display module 10 may also be embedded in the wearing piece 400 by other detachable methods such as threading, snap-on connection, etc.

[0076] In this embodiment, the wearing piece 400 may be glasses. In other embodiments, the wearing piece 400 may also be a helmet or the like.

[0077] Embodiment 2

[0078] like Fig.12 As shown, the difference between this embodiment and the first embodiment lies in the power module 300 .

[0079] In this embodiment, the power module 300 includes a plurality of battery cells 320 connected in series, and the battery cells 320 are arranged along an arc track or a circular track, wherein the battery cells 320 enclose a central accommodating cavity 310. Adjacent battery cells 320 are electrically connected via an electrical connection portion 330, thereby realizing the series connection between the plurality of battery cells 320. The electrical connection portion 330 is made of a conductive material.

[0080] In some other embodiments, a positive terminal and a negative terminal may be respectively provided on both sides of the battery cell 320. The two adjacent battery cells 320 are attached to each other so that the positive terminal of one battery cell 320 contacts the negative terminal of the other battery cell 320, thereby achieving electrical connection between the two battery cells 320, and thus there is no need to provide an additional electrical connection portion 330.
