Description

Technical Field

[0001] The invention relates to a head-mounted display device. Background Art

[0002] As the technology industry develops day by day, there are many types of head-mounted display devices. For example, when users wear such head-mounted display devices, they can see stereoscopic images, and the images will also change as the user's head turns, providing users with a more immersive experience. It can even be applied to the field of mixed reality (MR).

[0003] However, the interpupillary distance of each user is different. In order to allow the same head-mounted display device to provide different users with the same better user experience, some head-mounted display devices currently have the function of adjusting the interpupillary distance (IPD). For example, the interpupillary distance adjustment function can be achieved by electronic control to automatically adjust the interpupillary distance, but some users still have the need to manually adjust the interpupillary distance. Summary of the invention

[0004] The present invention is directed to a head mounted display device, which provides functions of automatically adjusting the pupil distance and manually adjusting the pupil distance.

[0005] The head mounted display device of the present invention comprises a first display, a second display, a transmission member, an electric control driver and a manual adjustment member. The transmission member connects the first display and the second display. The electric control driver is coupled to the transmission member. The electric control driver drives the transmission member in an electric control mode to adjust the distance between the first display and the second display. The manual adjustment member is detachably coupled to the transmission member. The manual adjustment member is coupled to and drives the transmission member in a manual mode to adjust the distance between the first display and the second display, and the manual adjustment member is separated from the transmission member in the electric control mode.

[0006] In one embodiment of the present invention, the transmission member has a fixed end and a first coupling end opposite to each other. The fixed end is fixedly connected to the electric control driver. The first coupling end is detachably coupled to the manual adjustment member.

[0007] In one embodiment of the present invention, the manual adjustment member includes a knob, a guide ring, a sliding member and a reset member. A driving section of the knob is pivoted in the guide ring. The driving section has a slide groove. The slide groove has a ramp section and a parallel section. The wall surface of the ramp section is not parallel to a rotation axis of the knob. The wall surface of the parallel section is parallel to the rotation axis. The inner surface of the guide ring has a plurality of guide grooves. The sliding member has a pivot end and a second coupling end opposite to each other. The pivot end is pivoted in the driving section. The outer surface of the sliding member has a guide rib. When a front section of the guide rib is slid in one of the guide grooves, the elastic restoring force of the reset member pushes against the sliding member so that the front section contacts the wall surface of the ramp section, and the first coupling end is away from the second coupling end. When the knob rotates relative to the guide ring and the front section is located in one of the guide grooves, the ramp section pushes the guide rib, and the guide ring limits the rotation of the sliding member. When the knob rotates relative to the guide ring and the guide rib is located outside the guide groove, the front section leaves the slope section and contacts the wall of the parallel section, the first coupling end couples to the second coupling end, the knob drives the transmission member to rotate via the sliding member, and the transmission member adjusts the distance between the first display and the second display.

[0008] In one embodiment of the present invention, the manual adjustment member includes a knob, a double push mechanism and a reset member. The knob is assembled to the double push mechanism. The knob has a second coupling end. In the electric control mode, the double push mechanism overcomes the elastic restoring force of the reset member to keep the knob in a first position, and the first coupling end is away from the second coupling end. In the manual mode, the elastic restoring force of the reset member keeps the knob in a second position, the first coupling end is coupled to the second coupling end, the knob drives the transmission member to rotate, and the transmission member adjusts the distance between the first display and the second display.

[0009] In one embodiment of the present invention, the first coupling end is constrained by the second coupling end and retained in the knob.

[0010] In one embodiment of the present invention, the head mounted display device further comprises a housing. The first display, the second display, the transmission member and the electric control driver are arranged in the housing. The knob is located in the housing when it is kept in the first position. The knob protrudes outside the housing when it is kept in the second position.

[0011] In one embodiment of the present invention, the transmission member is screwed to connect the first display and the second display.

[0012] In one embodiment of the present invention, the electronically controlled driver is a motor.

[0013] Based on the above, in the head-mounted display device of the present invention, the manual adjustment part is separated from the transmission part in the electric control mode. Therefore, the head-mounted display device of the present invention provides the functions of automatically adjusting the pupil distance and manually adjusting the pupil distance. In addition, the manual adjustment part is separated from the transmission part in the electric control mode, which can also avoid the manual adjustment part affecting the adjustment of the pupil distance in the electric control mode. When the user is not satisfied with the pupil distance automatically adjusted in the electric control mode, the user can also use the manual adjustment part to fine-tune the pupil distance.

[0026] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0027] Figure 1 Schematic diagram of a head mounted display device according to a first embodiment of the present invention. Figure 2 yes Figure 1 Schematic diagram of the electronic control mode of the head-mounted display device after the shell is removed. Figure 3 yes Figure 1 Illustration of the manual mode of the head mounted display device with the cover removed. Figures 1 to 3 The head mounted display device 50 of this embodiment includes a first display 52A, a second display 52B, a transmission member 54, an electric control driver 56 and a manual adjustment member 100. The first display 52A and the second display 52B include, for example, a display panel and an optical system, respectively. The optical system is, for example, a lens group, so that the image displayed on the display panel can be projected to the user's eyes through the lens group.

[0028] The transmission member 54 connects the first display 52A and the second display 52B. For example, the transmission member 54 of the present embodiment is threadedly connected to the first display 52A and the second display 52B, that is. The transmission member 54 connects the threaded portion of the first display 52A and the threaded portion of the second display 52B with the threaded portion. In the present embodiment, for example, when the transmission member 54 rotates in one direction, the thread of the transmission member 54 will drive the first display 52A and the second display 52B to move in a direction close to each other, so that the distance between the two is shortened. On the other hand, when the transmission member 54 rotates in the opposite direction, the thread of the transmission member 54 will drive the first display 52A and the second display 52B to move in a direction away from each other, so that the distance between the two is increased.

[0029] The electric control driver 56 is coupled to the transmission member 54. That is, the electric control driver 56 can drive the transmission member 54 to move, for example, to rotate. The electric control driver 56 drives the transmission member 54 in an electric control mode to adjust the distance between the first display 52A and the second display 52B. For example, in the electric control mode, the user can send a control signal to the electric control driver 56 through the operation interface of the head mounted display device 50, and the electric control driver 56 drives the transmission member 54 in an electric control mode to adjust the distance between the first display 52A and the second display 52B. Alternatively, in the electric control mode, the head mounted display device 50 can use a sensor to detect the pupil distance of the current user, and send a corresponding control signal to the electric control driver 56, and the electric control driver 56 drives the transmission member 54 in an electric control mode to adjust the distance between the first display 52A and the second display 52B. For example, the electric control driver 56 of this embodiment can be a motor.

[0030] The manual adjustment member 100 is detachably coupled to the transmission member 54. The manual adjustment member 100 is coupled to and drives the transmission member 54 in a manual mode to adjust the distance between the first display 52A and the second display 52B, and the manual adjustment member 100 is separated from the transmission member 54 in the electric control mode. In other words, in the electric control mode, because the manual adjustment member 100 is separated from the transmission member 54, the transmission member 54 will not drive the manual adjustment member 100, and even if the manual adjustment member 100 is rotated or fixed by an external force, it will not affect the movement of the transmission member 54, which can ensure that the electric control driver 56 can accurately adjust the distance between the first display 52A and the second display 52B. In other words, in the electric control mode, because the manual adjustment member 100 is separated from the transmission member 54, the rotation of the transmission member 54 will not drive the manual adjustment member 100 to rotate.

[0031] Figure 4 yes Figure 1 Schematic diagram of the manual adjustment parts and transmission parts of the head-mounted display device. Figure 4 The transmission member 54 of this embodiment has a fixed end 54A and a first coupling end 54B opposite to each other. The fixed end 54A is fixedly connected to the electric control driver 56. The first coupling end 54B is detachably coupled to the manual adjustment member 100.

[0032] The manual adjustment member 100 of this embodiment includes a knob 110, a guide ring 120, a sliding member 130 and a reset member 140. The knob 110 is adapted to rotate about a rotation axis A10. A driving section 112 of the knob 110 is pivotally disposed in the guide ring 120. That is, the knob 110 can rotate relative to the guide ring 120, while the guide ring 120 does not rotate relative to the entire head mounted display device 50, and the guide ring 120 and the knob 110 do not move on the rotation axis A10 relative to the entire head mounted display device 50.

[0033] Figures 5 to 7 yes Figure 1 Schematic diagram of the operation of the manual adjustment part and the transmission part of the head mounted display device from the electric control mode to the manual mode. Figure 4 and Figure 5 The driving section 112 has a slide groove 112A. The slide groove 112A has a slope section 112A2 and a parallel section 112A1. The slope section 112A2 is farther away from the first coupling end 54B of the transmission member 54 than the parallel section 112A1. The wall surface of the slope section 112A2 is not parallel to the rotation axis A10 of the knob 110. The wall surface of the parallel section 112A1 is parallel to the rotation axis A10. The inner surface of the guide ring 120 has a plurality of guide grooves 122. In order to simplify the drawings for clear understanding, Figures 5 to 7 Only one guide slot 122 is shown in the figure. The sliding member 130 has a pivot end 132 and a second coupling end 134 opposite to each other. The pivot end 132 is pivoted in the driving section 112. That is, the sliding member 130 and the knob 110 can rotate relative to each other. The outer surface of the sliding member 130 has a guide rib 136.

[0034] In such Figure 5 In the electric control mode shown, a front section 136A of the guide rib 136 is slidably disposed in one of the guide grooves 122, so that the sliding member 130 cannot rotate relative to the guide ring 120, and can only move relative to the guide ring 120 along the rotation axis A10. At the same time, the elastic restoring force of the reset member 140 pushes against the sliding member 130, so that the front section 136A remains in a state of contacting the wall surface of the slope section 112A2. In addition, the first coupling end 54B is away from the second coupling end 134. Therefore, the transmission member 54 and the sliding member 130 will not interfere with each other. At this time, the electric control driver 56 can accurately adjust the distance between the first display 52A and the second display 52B without being interfered by the knob 110.

[0035] In such Figure 6 In the process of switching from the electric control mode to the manual mode, the front section 136A of the guide rib 136 of the sliding member 130 is still located in one of the guide slots 122. When the knob 110 rotates relative to the guide ring 120, the ramp section 112A2 pushes the guide rib 136. Since the guide ring 120 restricts the rotation of the sliding member 130, the thrust exerted on the guide rib 136 by the ramp section 112A2 only causes the sliding member 130 to move in the rotation axis A10 and causes the guide rib 136 to slide in the direction of moving out of the guide slot 122.

[0036] In such Figure 7In the manual mode shown, the knob 110 continues to rotate relative to the guide ring 120, and the guide rib 136 is already outside the guide groove 122. At this time, the front section 136A of the guide rib 136 has left the ramp section 112A2, and the front section 136A of the guide rib 136 contacts the wall surface of the parallel section 112A1, and the first coupling end 54B couples with the second coupling end 134. Therefore, the guide ring 120 no longer restricts the rotation of the sliding member 130, and the ramp section 112A2 no longer pushes the guide rib 136 to move in the rotation axis A10. On the other hand, the rotation of the knob 110 can be transmitted to the front section 136A of the guide rib 136 via the wall surface of the parallel section 112A1, driving the sliding member 130 to rotate. At the same time, the second coupling end 134 of the sliding member 130 is coupled to the first coupling end 54B of the transmission member 54 , so that the sliding member 130 can drive the transmission member 54 to rotate to manually adjust the distance between the first display 52A and the second display 52B.

[0037] Figure 8 4 is a schematic diagram of a manual mode of a head mounted display device according to a second embodiment of the present invention. Fig. 9 yes Figure 8 Schematic diagram of the electronic control mode of the head mounted display device. Figure 8 and Fig. 9 The head mounted display device 60 of this embodiment and Figure 1 The head mounted display device 60 of the present embodiment is similar to the head mounted display device 50, and only the differences between the two are described here. The head mounted display device 60 of the present embodiment may further include a housing 68. Of course, Figure 1 The head mounted display device 50 may also include a housing (not shown). The first display 52A, the second display 52B, the transmission member 64 and the electric control driver 56 are disposed in the housing 68. Figure 8 In the manual mode, a portion of the knob 210 protrudes from the housing 68, making it easier for the user to rotate the knob 210. Fig. 9 In the electric control mode, the knob 210 is located inside the housing 68, so the user cannot turn the knob 210. In addition, the user can visually determine that it is the electric control mode and will not turn the knob 210 by mistake, which improves the user's operability and experience. The fact that the knob 210 can be stored inside the housing 68 also provides greater flexibility in appearance design.

[0038] Fig.10 yes Figure 8 Schematic diagram of the exploded view of the manual adjustment parts and transmission parts of the head-mounted display device. Fig.11 yes Figure 8 A perspective schematic diagram of the manual adjustment parts and transmission parts of the head-mounted display device in manual mode. Fig.12 yes Fig.11 Please refer to Figures 10 to 12The manual adjustment member 200 of this embodiment includes a knob 210, a double push mechanism 250 and a reset member 240. The knob 210 is assembled to the double push mechanism 250. Figure 8 and Fig. 9 In the manual mode, the double push mechanism 250 is omitted to make it easier to understand the position change of the knob 210. The knob 210 has a second coupling end 212. In the manual mode, the elastic restoring force of the reset member 240 keeps the knob 210 at a second position P12, that is, Figure 8 A portion of the middle knob 210 protrudes from the position outside the housing 68. At this time, the first coupling end 64B is coupled to the second coupling end 212. Therefore, the knob 210 can drive the transmission member 64 to rotate, and the transmission member 64 adjusts the distance between the first display 52A and the second display 52B.

[0039] Fig.13 yes Figure 8 A perspective schematic diagram of the manual adjustment parts and transmission parts of the head-mounted display device in the electronic control mode. Fig.14 yes Fig.13 Please refer to Fig.10 , Fig.13 and Fig.14 In the electric control mode, the double push mechanism 250 overcomes the elastic restoring force of the reset member 240 and keeps the knob 210 at a first position P14, that is, Fig. 9 The middle knob 210 is located in the housing 68. At this time, the first coupling end 64B of the transmission member 64 is away from the second coupling end 212. Therefore, the knob 210 does not interfere with the transmission member 64, and the electric control driver 56 can drive the transmission member 64 to adjust the distance between the first display 52A and the second display 52B.

[0040] The double push mechanism 250 of this embodiment can be a common double push mechanism. That is, when the knob 210 is not pressed, the double push mechanism 250 keeps the knob 210 at a position where a part of it protrudes outside the housing 68. Press the knob 210 once, and the double push mechanism 250 keeps the knob 210 at a position inside the housing 68. Press the knob 210 again, and the double push mechanism 250 releases the knob 210, and the elastic restoring force of the reset member 240 returns the knob 210 to a position where a part of it protrudes outside the housing 68. For example, the double push mechanism 250 of this embodiment includes a first component 252, a second component 254, and a third component 256. The first component 252 is combined with the knob 210 so that the two will not move relative to each other in the axial direction, but the first component 252 can rotate relative to the knob 210. The second component 254 has two guide grooves that can cooperate with the first component 252, so as to allow the knob 210 to stay at the first position P14 or the second position P12. The third component 256 has a structure that cooperates with the first component 252 , so that the first component 252 is rotated after contacting the third component 256 , so that the protrusion 252A on the first component 252 enters another guide groove on the second component 254 .

[0041] In this embodiment, the first coupling end 64B is limited by the second coupling end 212 and retained in the knob 210 , that is, the knob 210 will not completely disengage from the transmission member 64 .

[0042] In summary, in the head mounted display device of the present invention, the manual adjustment member is separated from the transmission member in the electric control mode, which can prevent the manual adjustment member from interfering with the effect of the electric control adjustment of the pupil distance and maintain accuracy. In addition, when the user is not satisfied with the pupil distance automatically adjusted in the electric control mode, the user can also use the manual adjustment member to fine-tune the pupil distance.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
