[0033] Embodiment 1

[0034] As Figure 1As shown in the figure, Embodiment 1 of the present utility model discloses a bracket device 10 and a projection device. The projection device includes the bracket device 10 and a projector 20. The bracket device 10 is used to support the projector 20. The bracket device 10 includes a bracket housing 11, a rotating member 12, and a light guide member 13. The rotating member 12 is disposed on the bracket housing 11 to fix and rotate the projector 20. The light guide member 13 is disposed on the bracket housing 11. The light guide member 13 is provided with a light incident portion 131 and a light exit portion 132. The light incident portion 131 is exposed on the side of the bracket housing 11 facing the projector 20, and the light exit portion 132 is exposed on the outer surface of the bracket housing 11. The orientation of the light incident portion 131 is perpendicular to the axis direction of the rotating member 12. The light guide member 13 is used to conduct the projection light beam of the projector 20 irradiated on the light incident portion 131 to the light exit portion 132. Among them, a light incident hole 111 and a light exit hole 112 are formed on the bracket housing 11. The light guide member 13 is fixed inside the bracket housing 11. The light incident portion 131 is exposed through the light incident hole 111, and the light exit portion 132 is exposed through the light exit hole 112. The light incident hole 111 corresponds to the light incident portion 131. The number of the light exit holes 112 and the light exit portions 132 is multiple, and the light exit holes 112 correspond to the light exit portions 132 one by one.

[0035] In this specific embodiment, the rotating member 12 is a damping rotating shaft, that is, the projector 20 and the bracket device 10 are damping rotatably connected through the damping rotating shaft. In some other specific embodiments, the rotating member 12 may also be a U-shaped or L-shaped support frame. The U-shaped or L-shaped support frame is rotatably connected to the bracket housing 11 through a rotating shaft. The bottom of the projector 20 is detachably fixed to the U-shaped or L-shaped support frame by screwing, so as to realize the rotating connection with the bracket device 10.

[0036] A display screen 22 is provided on the projector 20 for displaying pictures such as time, weather, photos, application programs, etc. The bracket housing 11 includes a connected base housing 113 and a bracket arm housing 114. The bracket arm housing 114 can be connected to the top or side of the base housing 113. The rotating member 12 is disposed on the bracket arm housing 114. The light incident hole 111 is formed on the top of the base housing 113, so that when the projector 20 rotates relative to the bracket device 10 to an upright state, the projection lens 21 can be directly facing the light incident hole 111; the light exit holes 112 can be formed on the outer side surface of the bracket arm housing 114 and / or the outer side surface of the base housing 113; among them, at least two light exit holes 112 are spaced apart along the height direction on the outer side surface of the bracket arm housing 114; and / or, at least two light exit holes 112 are spaced apart along the width direction on the front side surface and / or the top of the base housing 113.

[0037] In this specific embodiment, a support arm housing 114 is fixed on each of the left and right sides of the base housing 113. An incident light hole 111 is formed in the base housing 113. The incident light hole 111 is formed at the top of the base housing 113, and its specific position is in the area directly opposite to the projection lens 21 when the projector 20 rotates to face the base. In some embodiments, only one support arm housing 114 may be provided on the base housing 113.

[0038] Combined with Figure 6 , the light guide member 13 includes a light guide strip 133. The incident light portion 131 and the outgoing light portion 132 are respectively arranged on the light guide strip 133. Light guiding can be achieved inside the incident light portion 131, the outgoing light portion 132, and the light guide strip 133. The light guide strip 133 is fixedly arranged inside the base housing 113, and the incident light portion 131 provided on the light guide strip 133 protrudes relatively and at least partially located in the incident light hole 111 formed in the base housing 113 to be exposed on the outer surface of the support housing 11. The top end of the incident light portion 131 can be slightly lower than, higher than, or flush with the outer edge of the incident light hole 111. Among them, the distribution area where the incident light portion 131 is exposed covers the optical path projection area when the projection lens 21 faces the incident light portion 131, so that all the light emitted by the projection lens 21 enters the incident light portion 131. That is, the size of the incident light hole 111 covers the projection optical path, so that all the projection light can reach the incident light portion 131 on the light guide strip 133 in the incident light hole 111, or the distribution area where the incident light portion 131 is exposed can also be slightly smaller than the optical path projection area of the projection lens 21. The incident light portion 131 is adapted to the shape and size of the incident light hole 111 and can just be inserted into the incident light hole 111, and the shape can be circular or rectangular.

[0039] Among them, the light guide strip 133 is in a U-shaped long strip shape and is installed inside the base housing 113 and the support arm housing 114. The two ends of the light guide strip 133 extend from the base housing 113 to the two support arm housings 114 respectively and are fixed inside the support arm housing 114. A plurality of outgoing light portions 132 are arranged at intervals in the length direction of the light guide strip 133, and each outgoing light portion 132 is embedded into the outgoing light hole 112 on the support arm housing 114 / the base housing 113. Reflection coatings can be provided on other areas of the light guide strip 133 except for the incident light portion 131 and the outgoing light portion 132 to prevent light leakage. The outgoing surface of the light guide strip 133 at the outgoing light portion 132 is set as a matte surface so as to make the outgoing light form diffuse reflected light, and the outgoing light can be scattered in all directions, which is beneficial to the uniformity of the ambient brightness. The top of the outgoing light portion 132 can be flush with the surface of the support arm housing 114 / the base housing 113, or can protrude a part of the surface of the support arm housing 114 / the base housing 113 to increase the scattering area and reduce the brightness per unit area. In some other specific embodiments, if only one support arm housing 114 is provided, the corresponding light guide strip 133 can be in an L-shaped long strip shape.

[0040] Further, the combination body Figure 3 , Figure 4 and Figure 5 , a plurality of fixing posts 1133 and a plurality of fasteners (not shown in the figure) are provided on the inner wall of the top of the base housing 113 along the side of the light guide strip 133. The position of the light guide strip 133 close to the fixing posts 1133 is flush with the end face of the fixing posts 1133, so that the inner end face of each fastener abuts against the light guide strip 133 when each fastener is fixed to each fixing post 113. Specifically, further in combination with Figure 2 , the support arm housing 114 is divided into an inner housing 1141 and an outer housing 1142. The inner housing 1141 is close to the projector 20 side, and the inner housing 1141 is rotatably connected to the projector 20. The base housing 113 includes an upper housing 1131 and a lower housing 1132. The upper housing 1131 is closer to the projector 20 side, and the light inlet hole 111 is opened in the upper housing 1131. The inner housing 1141 of the support arm housing 114 is integrally provided with the upper housing 1131 of the base housing 113, and the outer housing 1142 of the support arm housing 114 is integrally provided with the lower housing 1132 of the base housing 113. The two integral structures are installed and fixed by means of buckles and locking screws. A fixing plate 1143 is provided in the support arm housing 114. The fixing plate 1143 is locked to the inner housing 1141 of the support arm housing 114. A first fixing hole 1337 is provided in the light guide strip 133 in the support arm housing 114, and a second fixing hole 11431 is provided on the fixing plate 1143. By screwing a screw into the first fixing hole 1337 and the second fixing hole 11431, the light guide strip 133 is fixed to the fixing plate 1143. On both sides of the inner side wall of the upper housing 1131 of the base housing 113 along the path where the light guide strip 133 is arranged, a number of fixing posts 1133 (such as screw hole fixing posts) are provided. The fixing posts 1133 abut against the edge of the light guide strip 133. Some structures (such as the concave avoidance groove 1336) on the light guide strip 133 are flush with the top surface of the fixing posts 1133. After screwing the screw into the fixing posts 1133, the nut of the screw can abut against this part of the structure (such as the concave avoidance groove 1336) of the light guide strip 133, so as to press the light guide strip 133 against the upper housing 1131. After the light guide strip 133 is fixed to the upper housing 1131 of the base housing 113 and the inner housing 1141 of the support arm housing 114, the integral inner housing 1141 and upper housing 1131 are fixedly assembled with the integral outer housing 1142 and lower housing 1132, so that the light-emitting part 132 of the light guide strip 133 is embedded into the light outlet hole 112 of the outer housing 1142 of the support arm housing 114. In some other embodiments, the light guide strip 133 can be pasted to the inner wall of the upper housing 1131 of the base housing 113 and / or the inner wall of the inner housing 1141 of the support arm housing 114 by setting an adhesive on the non-light-transmitting area provided on the light guide strip 133.

[0041] In various different specific embodiments, the light guide strip 133 is disposed on a part of the base housing 113. It can be fixed only on the inner side wall of the upper housing 1131 of the base housing 113 so that the light-emitting portion 132 is provided only at the top of the base housing 113. It can also be fixed only on the front inner wall of the base housing 113 so that the light-emitting portion 132 is provided only on the front side of the base housing 113. It can also be fixed simultaneously on the inner side wall of the upper housing 1131 of the base housing 113 and the front inner wall of the base housing 113 so that the light-emitting portions 132 are provided on the front side and the top of the base housing 113 at the same time. When the light guide strip 133 is disposed only on the front inner wall of the base housing 113, a light guide column can be connected below the light incident portion 131 to directly communicate with the light guide strip 133. When the light guide strip 133 is fixed simultaneously on the inner side wall of the upper housing 1131 of the base housing 113 and the front inner wall of the base housing 113, the front side and the top surface of the base housing 113 are respectively guided and emitted light through a light guide strip 133. Only these light guide strips 133 need to be connected together and the light path is conducted.

[0042] The light-emitting holes 112 of the support housing 11 can be provided on the top, the front side of the base housing 113, or on the outer side of the base housing 113 and the outer side of the support arm housing 114. The light guide strip 133 extends along the inner wall surface of the support housing 11 to pass through these light-emitting holes 112. The light-emitting holes 112 on the support arm housing 114 can be arranged at intervals along the length direction of the support arm housing 114. In addition to being in the shape of holes, the light-emitting holes 112 can also be provided as strip-shaped groove structures, and the light-emitting portions 132 of the light guide strip 133 can also be correspondingly designed as strip-shaped protrusions to be embedded in the strip-shaped grooves.

[0043] As Figure 4 shown, a convex arc surface 1311 is formed on the back side of the light incident portion 131 on the light guide strip 133. The outer surface of the convex arc surface 1311 is frosted, so that the incident light can be scattered evenly and enter the light guide strip 133. A reflective coating or a reflective film can also be provided on the outer surface of the convex arc surface 1311, which is beneficial to make more of the projection light incident from the light incident portion 131 enter the light guide channels on both sides after being reflected by the convex arc surface 1311, and helps to improve the light output of the light-emitting portion 132.

[0044] When the projection lens 21 faces the light incident part 131 of the light guide strip 133 on the base housing 113, the brightness mode can be manually adjusted by the user or automatically switched by the system according to the posture angle perception of the fuselage, so that the light output brightness of the projection lens 21 can be within a reasonable range and will not be too bright or too dark. When the user feels that the light output part 132 of the light guide strip 133 on the bracket housing 11 brings too high or insufficient brightness illumination to the environment, the light output brightness of the projection lens 21 can be adjusted by means of a remote control, a mobile phone APP, etc., and then the brightness of each light output part 132 on the bracket housing 11 can be adjusted. Alternatively, a photosensing module can also be set on the projector 20 or the bracket device 10 to identify the ambient brightness and automatically adjust the light output brightness of the projection lens 21 according to the ambient brightness.

[0045] Furthermore, a microphone can be set on the projector 20 or the bracket device 10. When a specific instruction of the user is recognized, it can automatically enter the night light mode. The projector 20 rotates relative to the bracket device 10 through an internal driving mechanism to direct the projection lens 21 towards the light incident part 131 of the base housing 11, and the light engine is lit to make the projection lens 21 emit a pure color light beam, such as pure white or yellow. The projection brightness can be determined by means of system default, user customization, ambient light brightness adaptation, etc.

[0046] Embodiment 2

[0047] As Figure 7 shown, Embodiment 2 of the present utility model discloses a bracket device 10 and a projection device. The following only further describes the differences between this embodiment and Embodiment 1, and the common points between this embodiment and Embodiment 1 will not be elaborated.

[0048] Combined Figure 8, in this embodiment, the light guide member 13 includes a first light guide strip 1331, a second light guide strip 1332 and a light guide column 1333. The first light guide strip 1331 is fixed to the inner wall of the top of the base housing 113, and the second light guide strip 1332 is fixedly arranged on the inner wall of the front side of the base housing 113. The light incident portion 131 is arranged on the first light guide strip 1331, the light exit portion 132 is arranged on the second light guide strip 1332, and the light exit hole 112 is opened on the front side of the base housing 113. The two ends of the light guide column 1333 are respectively connected to the bottom of the light incident portion 131 and the second light guide strip 1332. Specifically, a strip-shaped through groove or a round hole is opened on the front surface of the base housing 113 for embedding the light exit portion 132 with a corresponding shape on the second light guide strip 1332. Specifically, the top of the light incident portion 131 of the first light guide strip 1331 can be directly opposite to the projection lens 21, and the bottom is connected to a light guide column 1333. The other end of the light guide column 1333 is connected to a second light guide strip 1332. The second light guide strip 1332 is fixed to the inner wall of the front side of the base housing 113. The light guide column 1333 is used to conduct part of the light in the light incident portion 131 to the second light guide strip 1332. The light exit portion 132 of the second light guide strip 1332 is embedded in the light exit hole 112 opened on the front side surface of the base housing 113, such as a strip-shaped through groove hole or a round hole. In this way, the light can be conducted to the housing surfaces of the bracket device 10 in multiple different orientations, increasing the irradiation range.

[0049] Embodiment Three

[0050] As Figure 9 shown, the bracket device 10 and the projection device disclosed in this embodiment are based on Embodiment One or Embodiment Two, and a light shielding plate 116 is further provided on the top of the base housing 113. The light shielding plate 116 stands between the light incident portion 131 and the front side of the base housing 113, and the side of the light shielding plate 116 close to the light incident portion 131 is provided with a frosted curved surface.

[0051] Specifically, as Figure 7 and Figure 9As shown, in some settings, the light emitted by the projection lens 21 is relatively strong. After irradiating the light incident part 131 of the light guide strip 133, part of the light is directly reflected, which easily causes a local high-brightness phenomenon, affecting the user's visual perception in a dark environment and even potentially harming eyesight. Based on this, in this embodiment, a light blocking plate 116 is provided at the front end of the top of the base housing 113 to prevent the light reflected by the light incident part 131 from reflecting forward when the projection lens 21 irradiates the light incident part 131 downward. The rear surface of the light blocking plate 116, that is, the surface close to the light incident part 131, can be set as a frosted curved surface, thereby increasing the degree of light scattering irradiated thereon. This structure can make the light reflected by the light incident part 131 to the light blocking plate 116 and further reflect the light to the rear side of the support housing 113, so that the rear side of the support housing 113 can also be illuminated. In cooperation with Embodiment 1 and Embodiment 2, the support housing 113 can be illuminated in all directions of front, back, left, and right after being lit by the light of the projection lens 21, and can illuminate the dark environment more comprehensively and softly.

[0052] Embodiment 4

[0053] As Figure 10 shown, the difference between the support device 10 and the projection device disclosed in this embodiment and the previous embodiments is that in addition to including the base housing 113 and the support arm housing 114, the support housing 11 in this embodiment further includes a cross arm housing 115. The base housing 113, the support arm housing 114, and the cross arm housing 115 are sequentially connected to each other. The cross arm housing 115 is opposite to the base housing 113 in the height direction of the support device 10. The rotating member 12 is connected to the support arm housing 114. The light guide member 13 is disposed in the cross arm housing 115. The light incident hole 111 is opened on one side of the cross arm housing 115 facing the base housing 113. The light exit hole 112 is opened on the outer side surface of the cross arm housing 115 and / or the outer side surface of the support arm housing 114.

[0054] Referring to Figure 10 and Figure 11 , in this embodiment, the support housing 11 forms a closed structure similar to a picture frame, with the projector 20 located therein. A plurality of light exit holes 112 are also opened on the outer periphery of the upper half of the support housing 11 (corresponding to the upper half of the support arm housing 114 and the cross arm housing 115), and a light guide strip 133 is installed inside. Combining Figure 12 as shown, the light guide strip 133 in this embodiment includes an upper light guide strip 1334 in the upper half and a lower light guide strip 1335 in the lower half, and the two are separated and independent; or they can also be integrally connected, and the light can be conducted from the upper light guide strip 1334 above to the lower light guide strip 1335 below and exit from the lower light exit hole 112.
