Description

Technical Field

[0001] The present application relates to the field of projection technology, and in particular to a projection device. Background Art

[0002] Wearable technology products include wearable bracelets, rings or other devices that can be worn on preset parts of the limbs. Wearable devices can free people's limbs to the maximum extent and achieve a closer combination of human body and machine. When existing wearable devices are integrated with projection devices, the projection effect of the wearable devices is limited because the projection of the projection devices is relatively single. Utility Model Content

[0003] The present application provides a projection device, aiming to improve the problem of a single projection position of the projection device.

[0004] In order to achieve the above technical effects, a technical solution adopted by the present application is to provide a projection device, comprising:

[0005] A shell having a receiving groove, wherein a first side of the shell is configured to allow the shell to be placed on a hand of a wearer;

[0006] A light-transmitting area is provided on the housing, and the light-transmitting area is connected to the containing groove;

[0007] A shielding portion is provided on the housing, the shielding portion is adjacent to the light-transmitting area and

[0008] The projection module is arranged in the accommodating groove, wherein the projection module is configured to allow movement in the accommodating groove and move the projection module to project light from the light-transmitting area, and the projection module is also configured to allow movement in the accommodating groove and move the projection module to be at least partially shielded by the shielding part.

[0009] The example of the present application adopts a projection module arranged on the shell. On the one hand, the movement of the projection module relative to the light-transmitting area can be adjusted by moving the projection module relative to the accommodating groove. When it moves to the position of the light-transmitting area, it can project light, and when it moves to the shielding part, it can be blocked and no light is emitted. On the other hand, by arranging the projection module to be shielded by the shell, the projection module can form a retractable structure when needed.

[0036] When a projection device is integrated on the ring, an image can be projected in a preset direction through the projection device, so that the wearable device has more functions.

[0037] In some cases, the installation position of the projection device on the wearable device is relatively constant. When projecting, the position of the projected image is also limited, which is not convenient for adapting to the specific environment or usage scenario. The wearable device described in the example of this application can be a bracelet, a ring, a watch, etc. For the convenience of description, the following description takes the wearable device as a watch as an example.

[0038] See also Figures 1 to 20 The present application discloses an example of a projection device 10, including a housing 100, wherein the housing 100 is provided with a receiving groove 140, wherein a first side of the housing 100 is configured to allow the housing 100 to be mounted on a hand 700 of a wearer, wherein the first side may be a side in contact with the hand 700, i.e., an inner side, and the second side may be a side away from the hand 700, i.e., an outer side, and the first side and the second side may be two sides arranged opposite to each other; wherein the hand 700 may be a wrist or a finger; a light-transmitting area 131 is provided on the housing 100, and the light-transmitting area 131 may be an opening or a through hole on the housing 100, or the light-transmitting area 131 may be a 1 may be a light-transmitting or transparent protective sheet (not shown) covering the opening, or the housing 100 is made of a light-transmitting material, the light-transmitting area 131 is directly a part of the housing 100 itself, the shielding portion 132 is arranged on the housing 100, the light-transmitting area 131 is adjacent to the shielding portion 132, the light-transmitting area 131 may be arranged along the circumference of the housing 100, and the shielding portion 132 may be arranged along the circumference of the housing 100, wherein the light-transmitting area 131 and the shielding portion 132 may be arranged on the same side of the housing 100 in a circumferential arrangement, or the two may be respectively located on different sides of the housing 100. In other embodiments, the light-transmitting area 131 and the shielding portion 132 have a barrier, which can still be understood as an adjacent arrangement, as long as the distance between the two does not exceed 10 mm. The projection module 200 is disposed in the accommodating groove 140, and the accommodating groove 140 may be a notch, a groove or a sink structure. In some embodiments, the accommodating groove 140 may also be connected to the external environment, such as a notch opened in the outer ring wall 110 (described below) or the side wall 130 (described below) of the shell, etc. In another embodiment, the accommodating groove 140 may also be a sealed space formed by splicing a plurality of walls. The space of the accommodating groove 140 is larger than the projection module 200, so the projection module 200 can be allowed to move, slide or rotate in the accommodating groove 140; wherein the projection module 200 is configured to allow movement in the accommodating groove 140 and move the projection module 200 to the light transmission area 131 and project light toward the wearer's hand, such as Figure 1As shown, the projection module 200 can project onto the hand 700, such as the palm or the back of the palm, to form a projection outline 600. Of course, it can also be selected to project onto the finger area to form a projection outline. The projection module 200 is also configured to allow movement in the accommodating groove 140 and move the projection module 200 to be at least partially shielded by the shielding portion 132. The shielding portion 132 is opaque or the light transmittance of the shielding portion 132 is less than that of the light-transmitting area 131. It can be understood that, when viewed from the first plane projection direction, the first plane projection can be the plane where the light-transmitting area 131 is located or a plane parallel to the plane where the light-transmitting area 131 is located, for example, it can also be the plane where the side wall 130 corresponding to the following embodiment is located or a plane parallel to it, and the space of the accommodating groove 140 can span the light-transmitting area 131 and the shielding portion 132. Taking the annular housing 100 as an example, the accommodating groove 140 has a space extending along the circumference of the housing 100, and this space can allow the projection module 200 to be completely moved into the light-transmitting area 131, for example, it can be located in the middle or at any position on both sides of the light-transmitting area 131. The projection module 200 can also be moved to the junction of the light-transmitting area 131 and the shielding part 132, at which time the projection module 200 can be at least partially shielded by the shielding part 132, and when it is at least partially shielded, the light output of the projection module 200 is partially blocked. The projection module 200 can also be moved outside the light-transmitting area 131 and completely fall into the shielding part 132, so that the projection module 200 is completely shielded when viewed from the first plane projection direction, so that the projection module 200 is completely accommodated in the accommodating groove 140 or other grooves, and the light output of the projection module 200 can be completely blocked when it completely falls into the shielding part 132. In some embodiments, the projection module 200 can remain fixed, and the wall surface where the light-transmitting area 131 is located moves relatively, or the wall surface where the light-transmitting area 131 is located and the projection module 200 can move synchronously, so that the relative position of the light-transmitting area 131 and the projection module 200 can be changed.

[0039] In some embodiments, when the projection module 200 is located in the light-transmitting area 131, the projection module 200 can be in a state of driving to project light. When the projection module 200 is located at the junction of the light-transmitting area 131 and the shielding portion 132, the projection module 200 is at least partially shielded by the shielding portion 132. The projection module 200 can be in a low power consumption state, for example, the projection light becomes dim. When it completely enters the shielding portion 132, it can be in a shutdown or sleep state, and no light is projected at this time. Therefore, the projection module can be controlled to be in different power states according to the relative position of the projection module 200, thereby effectively reducing the power consumption of the projection module 200 in an easy-to-interactive manner.

[0040] In some embodiments, the shielding portion 132 is opaque, and this area can be made of an opaque material, or this area is coated with a black opaque coating. It can be understood that the shielding portion 132 can be a part of the main body of the shell 100, or the shielding portion 132 and the shell 100 are separately arranged, and the two are connected by bonding, clamping, fasteners, etc. Among them, the shell 100 can be annular and form an annular cavity 160. For example, the shell 100 can be a closed annular structure, or an open annular structure, or an annular structure with a gap. The annular cavity 160 is used to accommodate the hand 700. For example, when the annular cavity 160 is larger in size, it can accommodate the wrist, and when it is smaller in size, it can accommodate the finger, so it can be worn as a device such as a bracelet or a ring.

[0041] In some embodiments, the circumference of the shell 100 is not greater than 80 mm. It can be understood that the outer contour circumference of the annular cavity 160 is not greater than 80 mm, for example, it can be between 38 mm and 76 mm, so that it can adapt to the fingers of different users. The thickness of the shell is not greater than 8 mm, for example, it can be 2-5 mm, so as to avoid the discomfort between the two fingers caused by the thickness when worn on the fingers; in some embodiments, the thickness of the shell 100 gradually decreases in the circumferential direction D away from the light-transmitting hole 131, that is, the thickness of the activity space of the projection module 200 is allowed to be larger. This thickness may include the groove space of the accommodating groove 140, rather than the activity range of the projection module 200. Since the projection module 200 does not need to reach it, it can be made as thin as possible. For example, in some embodiments, the shell is away from both sides of the light-transmitting area 131, such as Figure 2 The thickness of the shell on the left and right sides is smaller than the thickness at the top light-transmitting area 131 .

[0042] In some embodiments, in conjunction with Figure 2-3 , the contour of the first side of the shell 100 includes a circle. Since the hand 700 (such as fingers, etc.) needs to be accommodated here, the circle can easily fit the hand 700 and reduce discomfort. The contour of the second side of the shell 100 away from the first side includes a non-circular shape. It can be understood that since the projection module 200 is thicker than the main control board or battery of the projection device 10, the required space is larger, but considering that the left and right sides are not too thick, resulting in a large distance between the two fingers, the shell can be made thinner away from the light-transmitting area 132, and the outer contour may not be circular, such as a runway or an elliptical shape, etc.; in other embodiments, if the thickness of the left and right sides allows, the second side contour can also be designed as a circular shape, the light-transmitting hole 131 and the shielding portion 132 are arranged along the circumferential direction D of the shell 100, the space of the accommodating groove 140 is larger than that of the projection module 200, and the projection module 200 is configured to allow movement in the space of the accommodating groove 140 along the circumferential direction D of the shell 100.

[0043] Continue reading Figure 2-5In some embodiments, the light-transmitting area 131 and the shielding portion 132 are located on the same side of the housing 100, and in the first plane projection, the light-transmitting area 131 and the shielding portion 132 do not overlap, for example, the light-transmitting area 131 and the shielding portion 132 are both on the same side of the housing but are arranged adjacently and do not overlap, or the light-transmitting area 131 and the shielding portion 132 are located on different sides of the housing and do not overlap when viewed from the first plane projection, wherein the first plane may be the plane where the light-transmitting area 131 is located or the plane where the side wall 130 of the housing 100 is located or a parallel plane. The light-transmitting area 131 and the shielding portion 132 may be arranged in the circumferential direction, wherein the shielding portion 132 may be located on two opposite sides of the light-transmitting area 131 in the circumferential direction. In the first plane projection, the light-transmitting area 131 and the shielding portion 132 at least partially overlap the accommodating groove 140 , that is, the length of the accommodating groove 140 spans the light-transmitting area 131 and the shielding portion 132 , thereby allowing the projection module 200 to move between the light-transmitting area 131 and the shielding portion 132 .

[0044] The projection area of ​​the projection module 200 relative to the light-transmitting area 131 is smaller than the area of ​​the light-transmitting area 131. For example, the light-transmitting area 131 may include a ring shape such as a circle, a quadrilateral, a runway shape or an ellipse. The projection module 200 as a whole may be cylindrical or prismatic. Therefore, when projected from the first plane, the outer contour of the projection module 200 may be a circle, an ellipse or a quadrilateral, etc., and the projection contour area of ​​the projection module 200 is smaller than the area of ​​the light-transmitting area 131, so that the projection module 200 can be moved to the light-transmitting area 131 to achieve complete projection of light. The projection area of ​​the projection module 200 relative to the shielding portion 132 is smaller than the area of ​​the shielding portion 132, wherein the shielding portion 132 includes a ring shape such as a circle, a quadrilateral, a runway shape or an ellipse, or other shapes such as an arc. Since the projection area of ​​the projection module 200 relative to the shielding portion 132 is smaller than the area of ​​the shielding portion 132, the projection module 200 can be fully shielded by the shielding portion 132.

[0045] Combined with reference Figure 4The projection module 200 includes a display assembly 210, an optical assembly 220 and a sleeve 230. The display assembly 210 is used to generate light. The optical assembly 220 is disposed on the light-emitting side of the display assembly 210 and receives light. The sleeve 230 is disposed on the outside of the optical assembly 220 and / or the display assembly 210. The sleeve 230 can be sleeved on the outside of the optical module 220, or on the outside of the display assembly 210, or on the outside of both the optical module 220 and the display assembly 210. The optical assembly 220 can be an optical lens or a combination of optical lenses. The display assembly 210 can be a micro display 212, which is used to provide display content for the device. The microdisplay 212 may include, but is not limited to, Micro-LED (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.

[0046] The optical component 220 forms a light-emitting surface 221; the opening area of ​​the light-transmitting area 131 is larger than the area of ​​the light-emitting surface 221, and the area of ​​the shielding portion 132 is larger than the area of ​​the light-emitting surface 221; it can be understood that the projection module 200 as a whole may be an irregular shape, for example, the light-emitting surface 221 is relatively small, and the area away from the light-emitting surface 221 is relatively large due to the need to place the display component 210, thus forming a non-cylindrical shape. Considering that the projection module 200 only needs the light-emitting surface 221 to be able to emit light, it is only necessary that the area of ​​the light-transmitting area 131 is larger than the area of ​​the light-emitting surface 221, and the area of ​​the shielding portion 132 is larger than the area of ​​the light-emitting surface 221, without considering the area size of the non-light-emitting surface 221. In some embodiments, the light-emitting surface 221 can be eccentrically arranged relative to the sleeve 230, so as to facilitate the design of the light-emitting angle. In another embodiment, the light-emitting surface 221 can be coaxially arranged relative to the central axis of the sleeve 230.

[0047] In some embodiments, the projection device also includes a light-transmitting protective sheet, which covers the light-transmitting area 131. For example, the light-transmitting area 131 can be an open hole structure. On the one hand, the protective sheet can be used to protect the projection module 200, and on the other hand, it can be used to prevent foreign matter from entering the accommodating cavity through the light-transmitting area 131, thereby reducing the risk of external damage to the optical component 220.

[0048] Please refer to Figures 2 to 10 The housing 100 may include an outer annular wall 110, an inner annular wall 120 and a side wall 130. The side wall 130 may include two oppositely disposed side walls, such as front and rear side walls 130. The outer annular wall 110, the inner annular wall 120 and the side wall 130 may be formed by injection molding or machining, or the above walls may be fixed by bonding or fixing members to form the housing 100. The inner annular wall 120 is located at a first side of the housing 100, and the inner annular wall 120 is spaced apart from the outer annular wall 110. The inner annular wall 120 is configured to contact the wearer's hand 700; and the side wall 130 is connected to the outer annular wall 110 and / or the inner annular wall 120. The receiving groove 140 may be formed by the side wall 130 and / or the outer ring wall 110, for example, it may be surrounded by the outer ring wall 110, the inner ring wall 120 and the side wall 130, or a groove may be formed on the outer ring wall 120 to form the receiving groove 140, or a groove may be formed on the side wall 130 to form the receiving groove 140. In this example, the outer ring wall 110 may be a side surface of the housing 100 that is arranged opposite to the inner ring wall 120, the outer ring wall 110 and the inner ring wall 120 are arranged at intervals, the outer ring wall 110 is arranged around the outer side of the inner ring wall 120, and a gap is formed between the outer ring wall 110 and the inner ring wall 120. The side of the inner ring wall 120 that is away from the outer ring wall 110 forms an annular cavity 160 for accommodating a finger or a wrist, and the annular cavity 160 may be a regular circular cavity, or the annular cavity 160 may be an irregular shape.

[0049] The side wall 130 is connected to the outer annular wall 110 and the inner annular wall 120, wherein the side wall 130 can be directly connected to the outer annular wall 110 and the inner annular wall 120, or the side wall 130 can be connected to the outer annular wall 110 and the inner annular wall 120 through an intermediate connector; the side wall 130 in this example can be fixedly connected to the outer annular wall 110 and the inner annular wall 120, or the side wall 130 can be movably connected relative to the outer annular wall 110 and the inner annular wall 120. There is at least one side wall 130, and the number of the side walls 130 in this example can be two, and the two side walls 130 can be arranged at intervals or in parallel. The side wall 130, the outer annular wall 110, and the inner annular wall 120 enclose a receiving groove 140. The receiving groove 140 can be generally annular in structure, and the receiving groove 140 serves as a space on the projection device for installing the projection module 200.

[0050] In some embodiments, the shell 100 includes an outer annular wall 110, an inner annular wall 120 and a side wall 130, the inner annular wall 120 is located on the first side of the shell 100, the inner annular wall 120 is spaced apart from the outer annular wall 110, and the inner annular wall 120 is configured to contact the wearer's hand 700; the side wall 130 is connected to the outer annular wall 110 and / or the inner annular wall 120, and the accommodating groove 140 is formed by the side wall 130 and / or the outer annular wall 110; for example, it can be formed by the three being surrounded or by opening a groove or notch in the side wall 130 or the outer annular wall 110.

[0051] The light-transmitting area 131 is disposed on the side wall 130 or the outer annular wall 110, and the shielding portion 132 is disposed on the side wall 130 or the outer annular wall 110, and the light-transmitting area 131 and the shielding portion 132 are located on different sides of the housing 100. For example, the shielding portion 132 is located on the outer annular wall 110, and the light-transmitting area 131 is located on the side wall 13, so the position adjustment of the projection module 200 relative to the light-transmitting area 131 and the shielding portion 132 can be achieved by rotating in a non-circumferential direction.

[0052] Please refer to Figure 3-4 Or 10-11, the projection module 200 moves to the projection of the light-transmitting area 131 and the light projection is emitted from the light-transmitting area 131, which means that the light-transmitting area 131 can be used for the light beam of the projection module 200 to penetrate, which means that when the projection module 200 moves to the position of the light-transmitting area 131, the light beam can pass through the light-transmitting area 131 and be projected in a preset direction. The light-transmitting area 131 and the shielding portion 132 in this example are arranged on the side wall 130, and the optical axis direction L of the projection module 200 is parallel to the axial direction 2a of the shell 100; in other embodiments, the light-transmitting area 131 and the shielding portion 132 are arranged on the outer ring wall 110, and the optical axis direction L of the projection module 200 is perpendicular to the axial direction 2a of the shell 100. In other embodiments, the direction of the optical axis L can also be perpendicular to the axial direction 2a or set at an angle, so that the light beam emitted by the projection module 200 can be output to the preset position via the light-transmitting area 131. The first plane may also refer to a plane perpendicular to the optical axis L of the projection module 200 as a reference plane, and the projection module 200 and the light-transmitting area 131 are projected onto the reference plane along the optical axis L of the projection module 200. When the projection module 200 is located within the projection of the light-transmitting area 131, the light beam emitted by the projection module 200 can pass through the light-transmitting area 131 and be transmitted outward. Figure 1 As shown in FIG. 6 , for example, the projection device may project a light beam toward the palm position to form a projection outline 600 at the palm position.

[0053] In this example, by setting a projection module 200 that can move relative to the light-transmitting area 131, the user can adjust the position of the projection module 200 as needed, and then flexibly adjust the position of the projection outline 600 generated by the projection module 200, thereby improving the flexibility of the projection result of the projection device. At the same time, the projection module 200 can be shielded by the shielding portion 132 to prevent light from passing through, thereby realizing hidden storage of the projection module, reducing the probability of damage to the projection module, and facilitating the use of the projection device 10 as a smart wearable device without easily producing a sense of strangeness in appearance, which is conducive to enhancing the user's use of this device in more scenarios.

[0054] The side wall 130 may be a wall surface perpendicular to the light emitting direction of the projection module 200. In this example, a light-transmitting area 131 is provided on the side wall 130 so that the light beam emitted by the projection module 200 can be output through the side wall 130. The light emitting direction (optical axis L) of the projection module 200 in this example may be parallel to the axial direction 2a of the inner ring wall 120, or may be arranged at a certain angle to the axial direction 2a of the inner ring wall 120. The display component 210 in this example may include a circuit board 211 and a micro display 212. The circuit board 211 and the micro display 212 are electrically connected. The circuit board 211 may include, for example, a voltage or driving circuit.

[0055] In some embodiments, Figure 5 , the light-transmitting area 131 may be a through hole on the side wall 130 that penetrates one of the side walls 130 in the thickness direction. The opening area of ​​the light-transmitting area 131 is larger than the area of ​​the light-emitting surface 221, which means that the total area of ​​the light-transmitting area 131 on the side wall 130 is larger than the total area of ​​the light-emitting surface 221. When the projection module 200 and the housing 100 move relative to each other, the relative position of the projection module 200 and the light-transmitting area 131 may change. When the opening area of ​​the light-transmitting area 131 is larger than the area of ​​the light-emitting surface 221, when the position of the light-emitting surface 221 of the projection module 200 changes relative to the light-transmitting area 131, as long as the projections of the light-emitting surface 221 of the projection module 200 and the light-transmitting area 131 overlap, the light beam output from the light-emitting surface 221 may be output through the light-transmitting area 131. In this example, when the light emitting surface 221 is completely offset from the light transmitting area 131 , the light beam output from the light emitting surface 221 cannot be output through the light transmitting area 131 , so that the projection module 200 is completely blocked by the shielding portion 132 . At this time, the projection module 200 can be in the storage state.

[0056] In some examples, the light-transmitting area 131 is disposed on the side wall 130, and the light-transmitting area 131 extends circumferentially along the side wall 130. For example, the light-transmitting area 131 may have an arc-shaped length direction on the side wall 130, and the length of the light-transmitting area 131 is greater than the length of the light-emitting surface 221. The length of the light-transmitting area 131 being greater than the length of the light-emitting surface 221 may be along the circumference of the side wall 130, and the length of the light-transmitting area 131 is greater than the length of the light-emitting surface 221 along the circumference of the side wall 130. In this example, the length of the light-transmitting area 131 is greater than the length of the light-emitting surface 221, so that the projection module 200 can project at multiple positions in the light-transmitting area 131, so that the projection position of the projection module 200 relative to the circumference of the housing 100 can be flexibly adjusted to meet the projection requirements under multi-angle wearing.

[0057] In some examples, see Figure 7 Or 13, the shielding portion 132 is located at both ends of the light-transmitting area 131. Of course, the shielding portion 132 can also be located at one end of the light-transmitting area 131, or the shielding portion 132 can also be located on the entire circumference of the light-transmitting area 131. In some embodiments, the accommodating groove 140 has a first end 141 and a second end 142 along the circumference of the shell 100, and the projection module 200 is movably arranged in the accommodating groove 140 between the first end 141 and the second end 142; a plane perpendicular to the axial direction of the shell 100 is defined as a first plane, and in the projection of the projection module 200 and the side wall 130 on the first plane, when the projection module 200 is at the first end 141, the light-emitting surface 221 at least partially overlaps with the side wall 130.

[0058] The accommodating groove 140 has a length direction, wherein the length direction of the accommodating groove 140 is consistent with the circumferential direction of the housing 100. The accommodating groove 140 has a first end 141 and a second end 142 along the circumferential direction of the housing 100, and the first end 141 and the second end 142 are arranged at intervals. When the projection module 200 moves relative to the housing 100, the projection module 200 moves between the first end 141 and the second end 142. The first plane is defined as a plane perpendicular to the axial direction of the housing 100, which means that Figure 2 As shown in the example, the axial direction of the housing 100 may be a first direction 2 a , and the first plane is a plane perpendicular to the first direction 2 a .

[0059] When the projection module 200 and the side wall 130 are projected onto the first plane along the first direction, in the projection plane, when the projection module 200 is at the first end 141, the light emitting surface 221 at least partially overlaps with the side wall 130, so that at least part of the light emitting surface 221 is blocked by the side wall 130. In this example, when the side wall 130 partially blocks the light emitting surface 221, the projection module 200 may partially emit light or not emit light, and when the side wall 130 completely blocks the light emitting surface 221, the light beam output by the projection module 200 may be completely blocked without emitting light. Of course, when the side wall 130 is made of a light-transmitting material, when the projection module 200 is moved to the first end 141, the projection module 200 can be set to a storage state, and at this time, external buttons or the like can be used to control whether the projection module 200 needs to emit light.

[0060] In some examples, the difference from the previous example is that when the projection module 200 is at the second end 142, the light emitting surface 221 at least partially overlaps with the side wall 130. When the projection module 200 and the side wall 130 are projected onto the first plane along the first direction, in the projection plane, when the projection module 200 is at the second end 142, the light emitting surface 221 at least partially overlaps with the side wall 130, so that at least part of the light emitting surface 221 is blocked by the side wall 130. In this example, when the side wall 130 partially blocks the light emitting surface 221, the projection module 200 can partially emit light, and when the side wall 130 completely blocks the light emitting surface 221, the light beam output by the projection module 200 can be completely blocked. In this example, when the side wall 130 is a light-transmitting material, when the projection module 200 is moved to the second end 142, the projection module 200 can be set to a storage state.

[0061] In some examples, see Figure 7-10 The projection device further includes a rotating member 300, which is connected to the sleeve 230. The rotating member 300 is at least partially exposed relative to the outer surface of the housing 100, and the rotating member 300 is configured to allow movement relative to the housing 100. The sleeve 230 can be a cylindrical structure sleeved on the outside of the optical component 220 or the display component 210. At least one of the optical component 220 and the display component 210 in this example can be located on the inner side of the sleeve 230. The sleeve 230 can serve as an intermediate connecting member between at least one of the display component 210 and the optical component 220 and the housing 100. In this example, the sleeve 230 and the optical component 220 and / or the display component 210 can be fixedly connected or detachably connected.

[0062] Please refer to Figure 7-9 Fig.15, the rotating member 300 is connected to the sleeve 230 so that the rotating member 300 can move synchronously with the sleeve 230. The rotating member 300 is at least partially exposed relative to the outer surface of the shell 100, which means that the rotating member 300 is in a visible state when observed from the outside of the shell 100. The rotating member 300 is configured to allow movement relative to the shell 100, which means that the rotating member 300 and the shell 100 can move relative to each other, including when one of the rotating member 300 and the shell 100 is in a relatively fixed state, the other can move along a preset direction, and also includes that the rotating member 300 and the shell 100 can move simultaneously along their respective preset directions. In this example, by setting the rotating member 300, the rotating member 300 can be used as an intermediate connecting member between the projection module 200 and the shell 100. The user can realize the relative movement of the projection module 200 and the shell 100 by operating the rotating member 300, thereby adjusting the relative position of the projection module 200 and the shell 100, and can also adjust the light output position of the projection module 200. In some embodiments, the outer surface of the rotating member 300 may also be provided with friction threads, etc., to facilitate user operation.

[0063] In some examples, see Figure 10-15 , the rotating member 300 includes an arc segment or an annular segment extending circumferentially along the inner annular wall 120, and the rotating member 300 is configured to allow rotation relative to the housing 100, and the rotation stroke of the rotating member 300 is greater than or equal to the length of the light-transmitting area 131. The rotating member 300 is an arc segment or annular segment extending circumferentially along the inner annular wall 120, which means that the rotating member 300 can be in the shape of an elongated strip, and the length direction of the rotating member 300 is arranged to extend circumferentially along the inner annular wall 120. The curvature of the rotating member 300 can be close to or the same as the curvature at the corresponding position of the inner annular wall 120. The rotating member 300 can be in the shape of an arc strip or an annular strip. When the rotating member 300 is in the shape of an annular strip, the rotating member 300 can be a closed annular structure, or a non-closed partial annular structure. The rotation stroke of the rotating member 300 is greater than or equal to the length of the light-transmitting area 131, which means that the maximum displacement of the geometric center of the rotating member 300 or the left-right movement of the rotating member 300 along the circumference of the inner annular wall 120 is greater than or equal to the total length of the light-transmitting area 131 along the circumference of the inner annular wall 120. In this example, when the rotating member 300 moves along the circumference of the inner annular wall 120, the rotating member 300 can drive the sleeve 230 to move synchronously, so that the projection module 200 can move to a preset position. When the projection module 200 moves to the first end 141 or the second end 142 of the accommodating groove 140 described in the above example, the projection module 200 can be shielded by the housing 100, so that the projection module 200 can partially emit light or be completely blocked, so as to facilitate the storage of the projection module 200.

[0064] For some examples, see Fig.11The rotating member 300 is provided with a first guide portion 310, and the shell 100 is provided with a second guide portion 150 on the side facing the accommodating groove 140. The first guide portion 310 is configured to be always positioned and connected to the second guide portion 150 when the rotating member 300 rotates relative to the shell 100.

[0065] The first guide portion 310 is connected to the rotating member 300. In this example, the first guide portion 310 can be integrally provided with the rotating member 300, or the first guide portion 310 can be separately provided with the rotating member 300 and connected to each other. The second guide portion 150 is provided on the housing 100. In this example, the first guide portion 310 and the second guide portion 150 can cooperate with a slide rail and a slide groove. In this example, when the rotating member 300 rotates relative to the housing 100, the first guide portion 310 is always positioned and connected to the second guide portion 150, which means that the first guide portion 310 and the second guide portion 150 can always play a role of mutual limitation and guidance, so that the rotating member 300 can move along the preset track formed by the first guide portion 310 and the second guide portion 150.

[0066] In some examples, see Figure 3-9 The rotating member 300 is arranged on the outer ring wall 110 and is at least partially exposed relative to the outer ring wall 110, wherein the outer ring wall 110 includes a first sub-outer ring wall 1101 and a second sub-outer ring wall 1102, and the rotating member 300 is located between the first sub-outer ring wall 1101 and the second sub-outer ring wall 1102, and is spaced apart from the first sub-outer ring wall 1101 and the second sub-outer ring wall 1102, and the rotating member 300 is configured to rotate relative to the first sub-outer ring wall 1101 and / or the second sub-outer ring wall 1102.

[0067] The outer ring wall 110 includes a first sub-outer ring wall 1101 and a second sub-outer ring wall 1102. In this example, the first sub-outer ring wall 1101 and the second sub-outer ring wall 1102 may be two annular structures spaced apart in the axial direction of the housing 100. A space for accommodating the rotating member 300 is formed between the first sub-outer ring wall 1101 and the second sub-outer ring wall 1102. The rotating member 300 may move in the circumferential direction of the housing 100 in the gap formed between the first sub-outer ring wall 1101 and the second sub-outer ring wall 1102. By forming the first sub-outer ring wall 1101 and the second sub-outer ring wall 1102, it is convenient to limit the rotating member 300 so that the rotating member 300 may be limited to a preset position outside the outer ring wall 110.

[0068] In some examples, a first engaging member 151 is provided on the outer ring wall 110, and a second engaging member 311 is provided on the rotating member 300, wherein when the rotating member 300 moves to the preset position, the first engaging member 151 is used to connect with the second engaging member 311. The first engaging member and the second engaging member in this example can be a buckle, a magnetic attraction module or other structures that can keep the rotating member 300 and the outer ring wall 110 in the current state; taking the first engaging member and the second engaging member as a magnetic attraction module as an example, one of the first engaging member and the second engaging member can be a magnet, and the other can be a magnetic attraction structure, such as a magnet or a ferromagnetic object. When the rotating member 300 moves to the preset position, the first engaging member can be mutually adsorbed with the second engaging member, so that the rotating member 300 maintains a stable state at the current preset position. The preset position described in this example can be the position of the first end 141 or the second end 142 of the accommodating groove 140 described above, or can be any other position between the first end 141 and the second end 142.

[0069] In some examples, the rotating member 300 is disposed on the inner annular wall 120 and is a part of the inner annular wall 120. The rotating member 300 is configured to be mounted and fit the hand of the wearer, and the rotating member 300 is rotatably connected to the side wall 130. The rotating member 300 can be an integral structure with the inner annular wall 120. When the projection device is worn on the hand, the rotating member 300 can face the hand of the wearer so that the rotating member 300 can fit the hand of the wearer. The rotating member 300 is rotatably connected to the side wall 130, which means that the rotating member 300 can rotate relative to the side wall 130, so that when the user rotates the rotating member 300, the rotating member 300 can move synchronously with the projection module 200.

[0070] Please refer to Fig.13 , Figures 16 to 20 In some examples, the projection device further includes an electrical component 400 and an electrical connector 410. The electrical component 400 is located in the receiving groove 140. The electrical component 400 includes an electrically connected battery and a main control board. The battery and the main control board are arranged along the circumference of the inner ring wall 120. The electrical connector 410 electrically connects the display component 210 and the electrical component 400. The sleeve 230 and the main control board are spaced apart. The projection device further includes a sensor 500. The sensor 500 is spaced apart from the projection module 200 and is electrically connected to the main control board. The sensor 500 is at least partially exposed relative to the inner ring wall 120 and is configured to detect the wearer's vital signs. The sensor 500 may be a contact sensor 500, which can be used to detect the user's blood pressure, pulse or other vital signs. The sensor 500 is at least partially exposed from the inner ring wall 120 so that the sensor 500 can contact the user's skin to obtain the user's vital signs.

[0071] The electrical component 400 is installed in the receiving groove 140 so that the electrical component 400 is received inside the housing 100. The electrical component 400 includes a battery, a main control board and a sensor 500, wherein the battery can be used to power the main control board, the projection module 200 and the sensor 500. In this example, the sleeve 230, the battery, the sensor 500 and the main control board are arranged along the circumference of the inner ring wall 120, and the battery, the sensor 500 and the main control board can also be arranged in other orders.

[0072] In some examples, see Figure 4 , 7 , 11, 13, the electrical connector 410 includes a redundant length section, the electrical connector 410 may include a flexible wire, the length of the redundant length section is greater than or equal to the movement stroke of the projection module 200 relative to the accommodating groove 140, that is, the wire length of the electrical connector 410 is adjustable. In this example, when the projection module 200 moves relatively, the length of the electrical connector 410 is adapted to the position of the projection module 200 to power or communicate with the projection module 200.

[0073] In some examples, see Figure 16-20 The electrical connector 410 includes a first electrical module 411 and a second electrical module 412 . The first electrical module 411 is electrically connected to the electrical component 400 . The second electrical module 412 is electrically connected to the projection module 200 . The first electrical module 411 is electrically connected to the second electrical module 412 .

[0074] In this example, the first electrical module and the second electrical module may be two parts of a connection structure such as a wire or a flexible circuit board 211 . The first electrical module and the second electrical module may also be separately provided and electrically connected to each other.

[0075] See also Figures 16 to 20 In some examples, the projection module 200 is movably connected to the shell 100 between a first position and a second position, and the first position and the second position are arranged along the circumference of the shell 100; one of the first electrical module 411 and the second electrical module 412 is a conductive rail extending along the circumference of the shell 100, and the other is a conductive bump, and the conductive bump is slidably connected to the conductive rail.

[0076] The projection module 200 can move between the first position and the second position, so that the relative position between the projection module 200 and the housing 100 can be changed, and then the position of the projection profile 600 of the projection module 200 can be changed. The first position and the second position are arranged along the circumference of the housing 100, so that when the projection module 200 moves between the first position and the second position, the projection module 200 can move relative to the circumference of the housing 100.

[0077] One of the first electrical module 411 and the second electrical module 412 is a conductive rail extending along the circumference of the housing 100 . The conductive rail may be a conductive structure formed by a metal part or a metal coating and extending along the circumference of the housing 100 .

[0078] The conductive bumps may be convex points or metal spheres formed by metal parts. When the projection module 200 and the housing 100 in this example are relatively displaced, the conductive bumps can be slidably connected to the conductive rails, so that the projection module 200 and the electrical component 400 can be electrically connected.

[0079] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
