Referring to fig. 1 to 5, in an embodiment, the first connecting structure 130 includes a first connecting plate disposed on the mounting bracket 120 and a first fixing element disposed on the first connecting plate for fixing the first connecting plate to the mounting hole 210 of the projection optical machine 200.
A first connector plate is mounted to the end of the mounting bracket 120, the first connector plate having a first securing assembly thereon. After the first connecting plate is installed in the installation hole 210 of the projection light machine 200, the first fixing component can be connected with the projection light machine 200 to establish connection between the first connecting plate and the projection light machine 200, so as to connect the installation bracket 120 and the projection light machine 200. It is understood that the form of the first connection plate is not limited in principle as long as the connection between the mounting bracket 120 and the projector engine 200 can be achieved. The first connecting plate is a plate-shaped member, and the first connecting plate may also be a connecting block, a connecting rod, or other members capable of being connected in other embodiments of the present invention.
Optionally, the projector engine 200 has a mounting hole 210 in the mounting hole 210, and the first fixing component can move into or out of the mounting hole 210. When the first fixing component moves into the mounting hole 210, the connection between the mounting bracket 120 and the projection light engine 200 can be realized; when the first fixing component is moved out of the mounting hole 210, the optical projector 200 can be detached from the mounting bracket 120.
In an embodiment, the first fixing assembly includes a first fastening member 132 and a first switch 131 disposed in the first connecting plate, and the first switch 131 can drive the first fastening member 132 to move, so that the first fastening member 132 is fastened to the projection optical device 200. The first fastener 132 can be disposed in the mounting hole 210 of the projector engine 200, and the first fastener 132 can reliably connect the projector engine 200 and the mounting bracket 120. When the first locking member 132 is moved out of the mounting hole 210 of the projection light engine 200, the mounting bracket 120 and the projection light engine 200 can be detached. Moreover, the first switch 131 is a component for detachably connecting the mounting bracket 120 and the projector engine 200. The first switch 131 can control the connection relationship between the mounting bracket 120 and the projection light machine 200, so as to realize detachable control and convenient use.
Alternatively, the first switch 131 may drive the first fastener 132 to move through the first connecting plate, and the first connecting plate drives the first fastener 132 to move, so that the first fastener 132 is connected to the mounting hole 210 of the projection optical device 200 or separated from the mounting hole 210. Alternatively, the first switch 131 may be directly connected to the first fastener 132, and the first switch 131 directly drives the first fastener 132 to move, so that the first fastener 132 is connected to the mounting hole 210 of the projection optical engine 200 or separated from the mounting hole 210, thereby connecting the mounting bracket 120 to the projection optical engine 200.
In one embodiment, the first fastener 132 can be rotatably slid into the mounting hole 210. Illustratively, an arcuate slot in communication with the mounting hole 210 may be added. When the first switch 131 drives the first fastener 132 to move, the first fastener 132 slides into the mounting hole 210 along the arc-shaped groove, so as to connect the mounting bracket 120 with the projection optical engine 200; when the optical module is disassembled, the first switch 131 can drive the first fastener 132 to slide into the arc-shaped groove from the mounting hole 210, so that the mounting bracket 120 is separated from the optical projector 200.
In an embodiment, the first switch 131 can also pull the first fastener 132 by a larger external force to control the first fastener 132 to move into or out of the projector 200.
In an embodiment, the first fastening member 132 is telescopically disposed in the first connecting plate, and the first switch 131 is connected to the first fastening member 132 to drive the first fastening member 132 to move. That is, the first switch 131 can control the first fastener 132 to perform a telescopic motion relative to the first connecting plate. Specifically, the first switch 131 may control the first fastening member 132 to extend out of the connecting plate, and at this time, the first fastening member 132 may be fastened in the mounting hole 210 of the projector 200; the first switch 131 can control the first fastener 132 to retract into the connection board, and at this time, the first fastener 132 can be installed on the projector engine 200 or detached from the projector engine 200.
In an embodiment, the first fixing assembly further includes a first elastic element 134, the first elastic element 134 is disposed in the first connecting plate and is abutted against the first connecting plate and the first fastening element 132, respectively, and the elastic force of the first elastic element 134 makes the first fastening element 132 extend out of the first connecting plate. The first elastic member 134 elastically connects the first connecting plate and the first fastening member 132. When the first switch 131 drives the first locking member 132 to retract into the first connecting plate, the first locking member 132 compresses the first elastic member 134. When the acting force of the first switch 131 disappears, the elastic force of the first elastic member 134 causes the first fastening member 132 to extend out of the first connection plate. In this way, the mounting bracket 120 can be mounted to the projector engine 200 through the first connecting structure 130. Alternatively, the first switch 131 is a toggle button or other component capable of controlling the movement of the first fastener 132. Alternatively, the first elastic member 134 is a spring or other elastic member such as a spring column, a bellows, etc.
In an embodiment, the first fastener 132 is a damping strip, a connecting column, or a hook, which can be fixedly connected. Exemplarily, the first fastener 132 is a damping strip, and the damping strip is installed behind the installation hole 210, so that the first connection board can be reliably connected to the projection light engine 200, and the connection between the installation bracket 120 and the projection light engine 200 is further achieved. Alternatively, the number of the first fastener 132 is plural, and the plural first fasteners 132 are arranged at intervals along the circumferential direction of the first connecting plate. Further, the plurality of first clamping members 132 may be uniformly or non-uniformly distributed.
In an embodiment, the projection bracket 100 further includes a first rotation joint 133, and the first rotation joint 133 is used to adjust the rotation angle of the projector engine 200. The first rotation joint 133 can be rotatably disposed on the mounting bracket 120, or the first rotation joint 133 can be rotatably disposed in the mounting hole 210 of the projector engine 200. The first rotating joint 133 can establish a rotating connection between the mounting bracket 120 and the light projector 200, so that the light projector 200 can adjust a rotating angle around the axis direction of the first rotating joint 133 to meet different projection requirements.
Optionally, the first rotating joint 133 is disposed on the mounting bracket 120, and at this time, the first rotating joint 133 and the first connecting plate are an integral structure. That is, the first rotation joint 133 can be detachably connected to the projector engine 200, and can rotate relative to the projector engine 200. At this time, the first locking member 132 is telescopically disposed on the first rotating joint 133, and the first rotating joint 133 and the projection optical device 200 are detachably connected by extending or retracting the first locking member 132. Moreover, after the first fastener 132 is installed in the installation hole 210 of the projection optical engine 200, the first fastener 132 can rotate in the installation hole 210, so as to adjust the rotation angle of the projection optical engine 200.
Moreover, after the first locking member 132 is a damping strip, the first rotating joint 133 drives the optical projection engine 200 to rotate by a certain angle, and the first locking member 132 can increase the friction between the first rotating joint 133 and the optical projection engine 200, so that the rotation angle of the optical projection engine 200 is fixed and is convenient to use. Of course, in other embodiments of the present invention, the first fastener 132 may also be fixed by increasing the friction coating or other ways of increasing the friction force.
Still alternatively, the first rotation joint 133 may be located on the projector engine 200. At this time, the first rotation joint 133 itself is rotatably connected to the projector engine 200. At this time, the mounting bracket 120 is connected to the projector engine 200 through the first connecting plate and the first fastener 132. This is substantially the same as the above principle that the mounting bracket 120 is directly connected to the projector engine 200, and thus the description thereof is omitted.
In a specific embodiment, referring to fig. 4 and 5, the first switch 131 performs a retracting motion of the two first clamping members 132 through the rack and pinion member, and performs a restoring motion of the two first clamping members 132 through the first elastic member 134. Specifically, when the first switch 131 is pulled downward along the arrow direction, the first switch 131 compresses the first elastic member 134, and drives the rack of the first fastening member 132 and the first fastening member 132 to move downward, meanwhile, the rack of the first fastening member 132 drives the meshed gears to rotate, and the meshed gears drive the rack of the other meshed first fastening member 132 to move against the elastic force of the first elastic member 134, so as to realize the contraction of the two first fastening members 132. When the external force of the first switch 131 disappears, the elastic force of the first elastic member 134 causes the two first locking members 132 and the racks connected thereto to be reset.
Of course, in other embodiments of the present invention, the first engaging member 132 can also realize linear telescopic movement through a telescopic rod, a sliding rail, and the like.
Optionally, the first connecting structure 130 further includes a magnetic element disposed in the mounting hole 210 of the optical projection engine 200, and the magnetic element can absorb the first fastening element 132, so that the first fastening element 132 is reliably fixed in the optical projection engine 200, and the first connecting structure 130 is prevented from being separated from the optical projection engine 200. Optionally, the magnetic attraction piece is a magnet or other component with an attraction effect.

Of course, in other embodiments of the present invention, the second connecting structure 140 may also be disposed at the end of the mounting bracket 120, and the mounting bracket 120 is connected to the mounting base 110 through the second connecting structure 140. It should be noted that the connection principle of the two connection manners is substantially the same, and the embodiment is described by taking only the second connection structure 140 disposed on the mounting base 110 as an example.
The second connecting structure 140 is installed in the mounting base 110. Specifically, a second connecting plate 141 is movably disposed in the mounting base 110, the second connecting plate 141 having a second fixing member thereon. Alternatively, the second connection plate 141 has a fixing hole, and the end of the mounting bracket 120 may be mounted in the mounting hole 210 and fixed by a second fixing member. The second fixing component is connected with the mounting bracket 120, and a connection between the second connecting plate 141 and the mounting bracket 120 is established, so as to realize the connection between the mounting bracket 120 and the mounting base 110. It will be appreciated that the form of the second connecting plate 141 is not limited in principle, as long as the connection of the mounting bracket 120 with the mounting base 110 can be achieved. The second connecting plate 141 is exemplarily provided in a plate shape, but of course, in other embodiments of the present invention, the second connecting plate 141 may also be a connecting block, a connecting rod, or the like, which can realize the connection.
In an embodiment, the second fixing assembly includes a second fastener 143 disposed on the second connecting plate 141 and a second switch 142, and the second switch 142 can drive the second fastener 143 to move, so that the second fastener 143 is fastened to the mounting base 110.

When the second fastener 143 is detached from the mounting bracket 120, the mounting bracket 120 and the mounting base 110 can be detached. Also, the second switch 142 is a component for realizing the detachable connection of the mounting bracket 120 with the mounting base 110.
