In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the front and back associated objects are a kind of "or" relationship.
[0011] The technical solutions disclosed in various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.
[0012] Please refer to Figures 1 to 15The embodiment of the present application discloses a head-mounted display device. The disclosed head-mounted display device can be a VR (Virtual Reality) device, an AR (Augmented Reality) device, an XR (Extended Reality) device, etc.
[0013] The above-mentioned head-mounted display device may specifically include a device body, electrical devices 120 and a circuit board, wherein: the device body may include a lens barrel 110, which is the mounting frame of the head-mounted display device, and an installation space is provided inside the lens barrel 110 for installing optical lenses, electrical devices 120 and other components, and the electrical devices 120 may include various light-emitting elements, sensors and the like.
[0014] like Figures 1 to 3 , Figures 10 to 12 As shown, the lens barrel 110 is a structure with openings at both ends, and the lens barrel 110 is provided with a mounting hole, which can be specifically set on the side wall of the lens barrel 110. A conductive connecting portion 111 is provided in the mounting hole, and the lens barrel 110 can be made of a plastic material, and the conductive connecting portion 111 can be made of a metal material, such as copper, silver, etc., and the shape of the conductive connecting portion 111 can be a cuboid, a cylinder, etc. The conductive connecting portion 111 is matched with the mounting hole plugging. Exemplarily, the conductive connecting portion 111 and the mounting hole of the lens barrel 110 can be connected by hot melting, dispensing, etc., or the conductive connecting portion 111 can also be embedded in the barrel wall of the lens barrel 110 by injection molding, and form a whole with the lens barrel 110.
[0015] The lens barrel 110 is provided with an electric device 120, and the circuit board is located outside the lens barrel 110. The electric device 120 needs to be interconnected with the circuit board to achieve corresponding functions. In order to achieve electrical connection between the electric device 120 and the circuit board, the conductive connection portion 111 may include a first electrical connection area 1111 exposed on the inner wall of the lens barrel 110 and a second electrical connection area 1112 exposed on the outer wall of the lens barrel 110. The electric device 120 can be electrically connected to the first electrical connection area 1111, and the circuit board can be electrically connected to the second electrical connection area 1112, so that the electric device 120 can be electrically connected to the circuit board through the conductive connection portion 111. In this process, since the lens barrel 110 can be made of plastic material, other areas of the conductive connection portion 111 except the first electrical connection area 1111 and the second electrical connection area 1112 can be insulated.
[0016] It should be noted that the electrical device 120 can directly contact the first electrical connection area 1111 of the conductive connection part 111 to achieve electrical connection, or use a wiring harness as a medium to achieve circuit conduction; similarly, the circuit board can directly contact the second electrical connection area 1112 of the conductive connection part 111 to achieve electrical connection, or use a wiring harness as a medium to achieve circuit conduction. The number of conductive connection parts 111 can be two or more, which can be selected according to the number of conductive contacts of the electrical device 120.
[0017] From the above description, it can be seen that the head-mounted display device disclosed in the embodiment of the present application improves the relevant technology. By cooperating the conductive connecting part 111 with the mounting hole plug, the circuit conduction between the electrical device 120 and the circuit board can be achieved without destroying the sealing of the lens barrel 110, thereby improving the dustproof and waterproof performance of the device.
[0018] like Figures 1 to 7 As shown, the conductive connecting portion 111 may include a first end 1113 and a second end 1114 that can move closer to or farther from each other, wherein the first end 1113 protrudes from the inner wall of the lens barrel 110, and the second end 1114 protrudes from the outer wall of the lens barrel 110, the first electrical connection area 1111 is provided at the first end 1113, and the second electrical connection area 1112 is provided at the second end 1114. The manner in which the first end 1113 and the second end 1114 move closer to or farther from each other may include: the conductive connecting portion 111 adopts a sleeve telescopic structure, and the first end 1113 and the second end 1114 can move closer to or farther from each other by telescoping; or the conductive connecting portion 111 is made of an elastic conductive material, and the first end 1113 and the second end 1114 can move closer to or farther from each other by self deformation.
[0019] The conductive connection portion 111 adopts the above-mentioned structural design. When in conductive contact with the electrical device 120 and the circuit board, it can ensure that the first end 1113 and the second end 1114 are in stable contact with the electrical device 120 and the circuit board respectively, thereby improving the stability of the electrical connection.
[0020] like Figures 1 to 7As shown, when the conductive connecting part 111 adopts a telescopic structure to realize the first end 1113 and the second end 1114 to move closer to or farther from each other, the conductive connecting part 111 may specifically include a cylindrical base 1115 and a conductive telescopic assembly 1116. The outer wall of the cylindrical base 1115 is sealed with the mounting hole, and the cylindrical base 1115 and the mounting hole can be connected by hot melting, dispensing glue, etc., or the cylindrical base 1115 can also be embedded in the barrel wall of the lens barrel 110 by injection molding, and form a whole with the lens barrel 110. The cylindrical base 1115 is a cylindrical structure with openings at both ends, wherein the first opening of the cylindrical base 1115 is close to the inside of the lens barrel 110, and the second opening of the cylindrical base 1115 is close to the outside of the lens barrel 110.
[0021] The conductive telescopic component 1116 is inserted into the cylindrical base 1115, one end of the conductive telescopic component 1116 protrudes from the inner wall of the lens barrel 110 to form the first end 1113 of the conductive connecting portion 111, and the other end of the conductive telescopic component 1116 protrudes from the outer wall of the lens barrel 110 to form the second end 1114 of the conductive connecting portion 111. The first end 1113 and the second end 1114 can be moved closer to or farther away from each other by telescoping the conductive telescopic component 1116. A metal spring or conductive glue is provided inside the conductive telescopic component 1116. Under the elastic support of the metal spring or the conductive glue, the two ends of the conductive telescopic component 1116 can move closer to or farther away from each other, thereby realizing the first end 1113 and the second end 1114 of the conductive connecting portion 111 moving closer to or farther away from each other.
[0022] like Figures 3 to 7 As shown, the above-mentioned conductive telescopic assembly 1116 may include a first telescopic member 1116a, a second telescopic member 1116b and an elastic conductive member 1116c, and the first telescopic member 1116a, the second telescopic member 1116b and the elastic conductive member 1116c are all made of conductive materials. The first telescopic member 1116a is arranged at the first opening of the cylindrical base 1115, and is slidably connected to the inner wall of the cylindrical base 1115 to form a first end 1113 of the conductive connecting portion 111, and the second telescopic member 1116b is arranged at the second opening of the cylindrical base 1115, and is slidably connected to the inner wall of the cylindrical base 1115 to form a second end 1114 of the conductive connecting portion 111. Since openings are provided at both ends of the cylindrical base 1115, in order to ensure the sealing of the cylindrical base 1115, the first telescopic member 1116a and the second telescopic member 1116b are respectively slidably connected to the inner wall of the cylindrical base 1115. When the surface of the first telescopic member 1116a and the surface of the second telescopic member 1116b are respectively in contact with the inner wall of the cylindrical base 1115, it can be ensured that the cylindrical base 1115 has good sealing.
[0023] The elastic conductive member 1116c is disposed in the cylindrical base 1115, and the two ends of the elastic conductive member 1116c along the axial direction of the cylindrical base 1115 are respectively connected to the first telescopic member 1116a and the second telescopic member 1116b to elastically support between the first telescopic member 1116a and the second telescopic member 1116b. When the first telescopic member 1116a and the second telescopic member 1116b are brought close to each other by external pressure, the elastic conductive member 1116c can be in a compressed state and accumulate elastic potential energy, so that the first telescopic member 1116a and the second telescopic member 1116b have a tendency to move away from each other, thereby enabling the first telescopic member 1116a and the second telescopic member 1116b to stably contact with other external conductive components. The elastic conductive member 1116c can specifically include a metal spring, a conductive adhesive, a conductive foam, etc.
[0024] To further improve the sealing performance of the cylindrical base 1115, Figures 4 to 7 As shown, the elastic conductive member 1116c is in contact with the inner wall of the cylindrical base 1115 at least when the first telescopic member 1116a and the second telescopic member 1116b are close to each other. Figure 4 and Figure 5 As shown, when the first telescopic member 1116a and the second telescopic member 1116b are not subjected to external pressure or the external pressure is small, there is a gap between the surface of the elastic conductive member 1116c and the inner wall of the cylindrical base 1115; Figure 6 and Figure 7 As shown, when the first telescopic member 1116a and the second telescopic member 1116b are subjected to a large external pressure, the elastic conductive member 1116c is deformed so that its surface fits the inner wall of the cylindrical base 1115, thereby improving the sealing performance of the cylindrical base 1115.
[0025] In an optional embodiment of the present application, the cylindrical base 1115 may also adopt a partitioned structure to improve the sealing performance. Specifically, a partition may be arranged inside the cylindrical base 1115 to separate the cylindrical base 1115 into an upper space and a lower space that are independent of each other, wherein the upper space is close to the interior of the cylinder, and the lower space is close to the exterior of the cylinder. The first telescopic member 1116a and the corresponding elastic conductive member 1116c may be arranged in the upper space, and the second telescopic member 1116b and the corresponding elastic conductive member 1116c may be arranged in the lower space, thereby achieving the mutual approach or distance between the first telescopic member 1116a and the second telescopic member 1116b and improving the sealing performance of the cylindrical base 1115.
[0026] like Figures 3 to 7As shown, in order to prevent the cylindrical base 1115 from sliding up and down in the mounting hole of the lens barrel 110, the conductive connecting portion 111 may further include a limiting column 1117, the limiting column 1117 is penetrated through the cylindrical wall of the cylindrical base 1115, both ends of the limiting column 1117 protrude from the outer wall of the cylindrical base 1115, and are embedded in the cylindrical wall of the lens barrel 110, specifically, can be embedded in the cylindrical wall where the mounting hole is located.
[0027] like Figures 3 to 7 As shown, the surface of the first telescopic member 1116a and the surface of the second telescopic member 1116b are both curved surfaces, that is, when the first electrical connection area 1111 and the second electrical connection area 1112 are in conductive contact with other components, the contact surface is a curved surface, which can reduce contact stress and thereby improve the reliability and durability of the equipment.
[0028] In an optional embodiment of the present application, Fig.15 As shown, the electrical device 120 may include a light source 121, which is disposed in the lens barrel 110 and electrically connected to the first electrical connection area 1111. The light source 121 may be electrically connected to the first electrical connection area 1111 through a wire harness, or may be directly electrically connected to the first electrical connection area 1111 through a metal contact. The device body also includes a receiving portion 130, which is connected to the barrel wall of the lens barrel 110. The specific connection method may be bolt connection, clamping, etc. The receiving portion 130 may receive the reflected light formed by the light source 121 on the eyeball 180, so as to track the position of the eyeball 180. The head-mounted display device may adjust the display parameters according to the position of the eyeball 180, so that the display screen of the head-mounted display device is well adapted to the position of the eyeball 180.
[0029] Eyeball 180 tracking is a technology that obtains real-time data of the human eye by measuring the information and movement of the eyeball 180. Taking the pupil corneal reflection method as an example, the light source 121 can be infrared light, and the receiving unit 130 can be a COMS (Complementary Metal Oxide Semiconductor) image sensor, a CCD (Charge Coupled Device) image sensor, etc. The specific principle is to irradiate some low-power infrared light into the human eye through the light source 121. This light that the human eye cannot see will be reflected on the cornea, and the infrared image will be captured by the corresponding sensor. After a series of processing, the eye features are obtained and the pupil position is identified, and the gaze direction and gaze position of the human eye are estimated.
[0030] It should be added that the above-mentioned receiving part 130 can also be connected to the circuit board in a similar manner to the light source 121, and a conductive connecting part 111 can also be set on the barrel wall of the lens barrel 110 where the receiving part 130 is located, so that the receiving part 130 can also be electrically connected to the circuit board through the conductive connecting part 111.
[0031] The above-mentioned light source 121 may include a light source body 1211, a first electrical connector 1212, and a second electrical connector 1213.

The light source body 1211 is electrically connected to the first electrical connector 1212. The light source body 1211 may be integrated on the first electrical connector 1212 to achieve electrical connection, or may be electrically connected through a plug connector. The light source body 1211 and the first electrical connector 1212 are both located in the lens barrel 110. The first electrical connector 1212 is provided with a third electrical connection area 1212a, which may be a copper-exposed area of the first electrical connector 1212. The first electrical connector 1212 may be in conductive contact with the first electrical connection area 1111 of the conductive connection portion 111 through the third electrical connection area 1212a.
[0032] The second electrical connector 1213 is disposed outside the lens barrel 110 and is electrically connected to the circuit board. The connection between the second electrical connector 1213 and the circuit board may be welding, plugging, etc. The second electrical connector 1213 is provided with a fourth electrical connection area 1213a. The fourth electrical connection area 1213a may be a copper-exposed area of the second electrical connector 1213. The second electrical connector 1213 may be in conductive contact with the second electrical connection area 1112 of the conductive connection portion 111 through the fourth electrical connection area 1213a. By providing the first electrical connector 1212 and the second electrical connector 1213, the arrangement of the light source body 1211 in the lens barrel 110 is more flexible.
[0033] like Fig.13 and Fig.14As shown, in order to improve the stability of the contact between the first electrical connector 1212, the second electrical connector 1213 and the conductive connection portion 111, a conductive spring 1214 can be provided in the third electrical connection area 1212a of the first electrical connector 1212, and the first electrical connector 1212 can elastically contact the first electrical connection area 1111 through the conductive spring 1214. Similarly, a conductive spring 1214 is provided in the fourth electrical connection area 1213a of the second electrical connector 1213, and the second electrical connector 1213 can elastically contact the second electrical connection area 1112 through the conductive spring 1214. By providing the conductive spring 1214, the first electrical connector 1212, the second electrical connector 1213 and the conductive connection portion 111 can be stably contacted, thereby improving the stability of the electrical connection.
[0034] like Figures 1 to 3 , Figures 10 to 12 As shown, the inner wall of the lens barrel 110 is provided with an annular stage 112, which can extend radially outwardly along the lens barrel 110, the mounting hole is provided on the annular stage 112, and the conductive connection portion 111 can be embedded in the annular stage 112. Based on the structure of the annular stage 112, the first electrical connector 1212 is also correspondingly provided as an annular structure, the first electrical connector 1212 includes a first surface and a second surface opposite to each other, the number of the light source bodies 1211 is multiple, the light source bodies 1211 can be provided on the first surface of the first electrical connector 1212 in an integrated manner, and the multiple light source bodies 1211 are provided at intervals along the circumference of the first electrical connector 1212. At least a portion of the second surface of the first electrical connector 1212 is in contact with the end surface of the annular stage 112, and the third electrical connection area 1212a is provided on the second surface, so that the first electrical connector 1212 can be in contact with the conductive connection portion 111 for electrical connection.
[0035] like Figure 3 and Figure 8 As shown, the end face of the annular platform 112 is provided with a positioning column 113, and the first electrical connector 1212 is provided with a first positioning hole 1212b. During actual assembly, the positioning column 113 can be extended into the first positioning hole 1212b to achieve positioning cooperation, so that the first electrical connector 1212 can be installed at a predetermined position of the annular platform 112. Moreover, the limiting effect of the positioning column 113 and the first positioning hole 1212b also makes it difficult for the first electrical connector 1212 to be displaced on the annular platform 112, thereby improving the stability of the assembly.
[0036] like Figures 1 to 3 , Figures 10 to 12As shown, the device body may also include a first pressing plate 140, which is connected to the inner wall of the lens barrel 110, and the end surface of the first pressing plate 140 is in contact with the first surface of the first electrical connector 1212. When the first pressing plate 140 applies a certain pressure to the first electrical connector 1212, the second surface of the first electrical connector 1212 may be pressed against the end surface of the annular stage 112, thereby improving the stability of the conductive contact between the first electrical connector 1212 and the conductive connecting portion 111. In addition, in order to facilitate the positioning and installation of the first pressing plate 140, the first pressing plate 140 is also provided with a second positioning hole 141, and the positioning column 113 extends into the second positioning hole 141 to achieve positioning and matching; in order to prevent the first pressing plate 140 from blocking the light source body 1211, an avoidance notch may also be provided on the first pressing plate 140, and the avoidance notch is provided corresponding to the light source body 1211.

The second pressure plate 150 may apply a pre-tightening force to the second electrical connector 1213 to press the fourth electrical connection area 1213a against the second electrical connection area 1112, thereby improving the stability of the electrical connection.
[0038] like Figure 1 , Fig.10 , Fig.15 As shown, the device body also includes a display module 160 and an optical module 170. The display module 160 is arranged at one end of the lens barrel 110. The display module 160 is mainly used to display images. The optical module 170 is arranged inside the lens barrel 110 and close to the other end of the lens barrel 110.

The infrared light emitted by the light source body shines into the human eye. This light that is invisible to the human eye will be reflected on the cornea and the infrared image will be captured by the corresponding receiving part. After a series of processing, the eye features are obtained and the pupil position is identified, and the gaze direction and gaze position of the human eye are estimated, thereby realizing eye tracking.
