Description

Technical Field

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

[0002] Projectors are widely used in education, entertainment, business and other scenarios, especially in home applications. At different times, users may place the projector in different locations to watch movies, such as in the living room, bedroom, etc. When placing the projector in different locations, it is necessary to adjust the height of the projector, etc., in view of the differences in height and angle between the screen or the wall on which the projection can be made and the placement location. In the related art, a bracket is usually used to support the projector, and the height and projection angle of the projector are adjusted by the bracket at the same time, which makes it inconvenient to adjust the height of the projector, etc. Moreover, in the process of using the projector, it is often necessary to turn on the projector first, and then adjust the height and projection angle of the projector through the bracket according to the position of the projected image. In this way, while adjusting the height and projection angle of the projector, it is not possible to automatically control the working mode of the projector. Utility Model Content

[0003] The present application provides a projection device, which is helpful to simplify the operation of adjusting the height of a projection host in the projection device.

[0005] The projection device provided by the present application is provided with a base, and the base can provide support for the projection device, so that the projection device can be placed in a placement position, and other components in the projection device can be installed on the base. At the same time, a motion mechanism is fixed on the base, and the projection host is connected to the end of the motion mechanism away from the base, so that in the process of using the projection device, the position of the projection host relative to the base can be adjusted by the motion mechanism, that is, the relative placement position of the projection host can be adjusted to different heights. Compared with the related art, in which the height of the projection device is adjusted by a bracket, the projection device provided by the present application can adjust the height of the projection host relative to the placement position by the motion mechanism of the projection device itself, thereby saving the step of installing the bracket, and further facilitating the operation of adjusting the height of the projection host in the projection device.

[0006] In a possible implementation of the present application, the motion mechanism includes a guide member and a moving member that are slidably connected, the guide member is fixed on a base, and the projection host is connected to the moving member.

[0007] In the technical solution of the present application, since a slidingly connected guide member and a moving member are provided in the motion mechanism, the guide member can be fixedly connected to the base to limit the movement direction of the moving member through the guide member, and by connecting the projection host to the moving member, the projection host can be moved relative to the base along a fixed path in a direction away from or close to the base.

[0008] In one possible implementation of the present application, the motion mechanism also includes a sliding member, one of the guide member and the moving member is fixedly connected to the sliding member, and the other of the guide member and the moving member is slidably connected to the sliding member; the guide member has a limiting structure, and the limiting structure is used to limit the movement position of the moving member relative to the guide member.

[0009] In the technical solution of the present application, since a sliding member is provided between the guide member and the moving member, the sliding member can reduce the wear of the guide member and the moving member, which is beneficial to improving the service life of the motion mechanism. At the same time, a limiting structure is provided on the guide member, and the moving position of the moving member relative to the guide member can be limited by the limiting structure, which is beneficial to reducing the risk of the moving member detaching from the guide member.

[0010] In a possible implementation of the present application, the projection host is rotatably connected to the motion mechanism.

[0011] In the technical solution of the present application, since the projection host is rotatably connected to the motion mechanism, when the projection host is moved to a position away from the base by the motion mechanism, the projection host can be rotated to adjust the pitch angle of the projection host, thereby facilitating the adjustment of the projection direction of the projection device.

[0012] In one possible implementation of the present application, a first switch component is arranged between the projection host and the base, and the first switch component is electrically connected to the controller of the projection device; when the projection host moves away from or close to the base through the motion mechanism, the first switch component generates a corresponding control signal.

In this way, while adjusting the height of the projection host, the working mode of the projection device can be automatically controlled, thereby saving the operating steps of turning on or off the projection host.

[0014] In one possible implementation of the present application, the first switch component includes a Hall device and a magnetic component, one of the Hall device and the magnetic component is arranged on the projection host, the other of the Hall device and the magnetic component is arranged on the substrate, and the Hall device is electrically connected to the controller of the projection device.

[0015] In the technical solution of the present application, since the first switch assembly is configured to include a Hall device and a magnetic component, the Hall device and the magnetic component can be respectively arranged at corresponding positions on the base and the projection host, and an electrical signal can be generated by the Hall device during the relative movement of the projection host to the base, so that a control signal can be input to the controller of the projection device. In addition, the Hall device and the magnetic component are non-contact in the process of generating the electrical signal, thereby reducing the risk of failure of the first switch assembly due to mechanical wear.

[0016] In one possible implementation of the present application, an angle detection component is provided on the projection host, and the angle detection component is electrically connected to the controller. The angle detection component is used to detect the deflection angle of the projection host relative to the base, and the controller is used to control the projection mode of the projection host according to the deflection angle.

[0017] In the technical solution of the present application, since an angle detection component is provided on the projection host and is electrically connected to the controller, a preset control signal can be input to the controller through the angle detection component during the process of rotating the projection host, so as to control the projection host to automatically enter the corresponding projection mode according to different deflection angles, thereby reducing the operating steps of the projection host.

[0018] In a possible implementation of the present application, a light assembly is provided on the projection host, the light assembly is electrically connected to a controller, and the controller is further used to control a light mode of the light assembly according to a deflection angle.

[0036] The working principle of the projection device is to irradiate light onto the image display element to generate an image, and then project the image through the lens to form a projection screen on the projection surface. During the use of the projection device, it is often necessary to adjust the height and projection angle of the projection host of the projection device so that the projection screen can be located within a suitable projection surface. Therefore, a projection device that is easy to adjust the height and projection angle of the projection host of the projection device is required.

[0037] The present application embodiment provides a projection device, referring to Figure 1 , Figure 2 and Figure 3 , Figure 1 and Figure 2 The schematic diagrams of the structure of the projection device provided by the present application in different postures are shown respectively, Figure 3 The schematic diagram of the assembly structure of the motion mechanism in the projection device provided by the present application is shown. The projection device provided by the embodiment of the present application includes: the projection device provided by the present application includes: a base 1, a motion mechanism 3 and a projection host 2; wherein one end of the motion mechanism 3 is fixed on the base 1; the projection host 2 is installed on the end of the motion mechanism 3 away from the base 1; the projection host 2 can move in a direction away from or close to the base 1 through the motion mechanism 3.

[0038] In the embodiment of the present application, the base 1 can provide support for the projection device, so that the projection device can be placed on a desktop, the ground, or other placement locations, and the projection device can also be fixed on a bracket through the base 1. The base 1 can also provide installation locations and support for other components in the projection device, so as to form the projection device through assembly.

[0039] Exemplarily, the base 1 can be configured as a structure including a base 11 and a support member 12. The base 11 can be configured as a cylindrical, cubical, or other structural form, and a receiving cavity can be formed in the base 11 to facilitate installation of other parts of the projection device in the base 11. The support member 12 can be configured as a long columnar body, such as a cylinder, a triangular prism, a quadrangular prism, or a columnar body with an elliptical cross section; one end of the support member 12 can be fixedly connected to the side wall of the base 11, or the support member 12 and the base 11 can be processed by integral molding; and a receiving cavity can be formed in the support member 12 to facilitate installation of the motion mechanism 3 in the receiving cavity.

[0040] In the embodiment of the present application, the projection host 2 may be a part of the projection device that can generate a projection screen. For example, the projection host 2 includes a projection component and a lens component, the projection component can generate an image, and the light beam of the image generated by the projection component can form a projection screen of a desired size after being adjusted by the lens component.

[0041] In the embodiment of the present application, the motion mechanism 3 may be a structure capable of generating linear motion, and the motion mechanism 3 may be installed in a receiving cavity on the support member 12 of the base 1. For example, a part of the motion mechanism 3 may be fixed on the radial side wall of the base 11 of the base 1, and the projection host 2 may be connected to another part of the motion mechanism 3, wherein the two parts of the motion mechanism 3 may generate relative linear motion. Figure 2 As shown, the projection host 2 can be moved relative to the base 1 along the lifting direction L, so as to adjust the height of the projection host 2 relative to the placement position.

[0042] The projection device provided in the embodiment of the present application is provided with a base 1, and the base 1 can provide support for the projection device, so that the projection device can be placed in a placement position, and other components in the projection device can be installed on the base 1. At the same time, a motion mechanism 3 is fixed on the base 1, and the projection host 2 is connected to the end of the motion mechanism 3 away from the base 1, so that in the process of using the projection device, the position of the projection host 2 relative to the base 1 can be adjusted by the motion mechanism 3, that is, the relative placement position of the projection host 2 can be adjusted to different heights. Compared with the related art, in which the height of the projection device is adjusted by a bracket, the projection device provided in the embodiment of the present application can adjust the height of the projection host 2 relative to the placement position by the motion mechanism 3 of the projection device itself, thereby saving the step of installing the bracket, and further facilitating the operation of adjusting the height of the projection host 2 in the projection device.

[0043] In some possible embodiments of the present application, refer to Figure 4 , Figure 4 The schematic diagram of the exploded structure of the motion mechanism in the projection device provided by the present application is shown. The motion mechanism 3 includes a guide member 31 and a moving member 32 which are slidably connected. The guide member 31 is fixed on the base 1 , and the projection host 2 is connected to the moving member 32 .

[0044] In the present application embodiment, Figure 3 and Figure 4 As shown, the motion mechanism 3 can be configured to include a guide member 31 and a moving member 32, and the moving member 32 is connected to the guide member 31 in a sliding connection so that the motion mechanism 3 can generate linear motion.

[0045] For example, Figure 4 As shown, the guide member 31 can be set as a long plate-like structure, and a guide rail 312 is set at one end of the plate-like guide member 31, and the other end of the plate-like guide member 31 is used as a fixed end 313. For example, a through hole can be set at the fixed end 313 of the guide member 31, so that a screw or a rivet can be passed through the through hole of the fixed end 313 to fix the guide member 31 to the base 11 in the base 1. The edge parts of both sides of the plate-like guide member 31 can be used as the guide rail 312. The guide member 31 can be formed by stamping a metal plate.

[0046] In another example, the moving member 32 can be set as an annular structure with an opening in the cross section, that is, an approximately U-shaped sliding structure is formed on both sides of the moving member 32, and the sliding structure matches the guide rail 312 on the guide member 31. In this way, the moving member 32 can be slidably clamped on the guide rail 312 so that the moving member 32 can slide on the guide rail 312 relative to the guide member 31. A connecting structure can also be set at one end of the moving member 32 to facilitate the installation of the projection host 2. For example, the connecting structure can be set to a plurality of through holes so that the projection host 2 can be connected to the moving member 32 by screws or rivets. The moving member 32 can also be formed by stamping a metal sheet.

[0047] In the above embodiment, since a slidably connected guide member 31 and a movable member 32 are provided in the motion mechanism 3, the guide member 31 can be fixedly connected to the base 1 so as to limit the movement direction of the movable member 32 by the guide member 31, and by connecting the projection host 2 to the movable member 32, the projection host 2 can be moved relative to the base 1 along a fixed path in a direction away from or close to the base 1.

[0048] In some possible embodiments of the present application, the moving mechanism 3 also includes a sliding member 33, one of the guide member 31 and the moving member 32 is fixedly connected to the sliding member 33, and the other of the guide member 31 and the moving member 32 is slidably connected to the sliding member 33; the guide member 31 has a limiting structure 311, and the limiting structure 311 is used to limit the moving position of the moving member 32 relative to the guide member 31.

[0049] In the present application embodiment, Figure 3 and Figure 4 As shown, a sliding member 33 may be provided between the guide member 31 and the moving member 32 so that the guide member 31 and the moving member 32 are slidably connected through the sliding member 33 .

[0050] Exemplary, the sliding member 33 can be set to the strip-shaped structural form of the approximate U-shaped cross section, that is, the groove matching the guide rail 312 on the guide member 31 is set on the sliding member 33, so that the sliding member 33 can be slidably installed on the guide rail 312 through the groove. Simultaneously, the clamping structure matching the profile of the sliding member 33 can be set on the moving member 32, so that the moving member 32 is fixedly connected with the sliding member 33 through the clamping structure. For example, a projection can be set on the outside of the sliding member 33, the clamping structure of the moving member 32 is set to the approximate U-shaped clamping groove of the cross section, and the notch matching the projection on the sliding member 33 is set on the groove wall of the clamping groove, so that the sliding member 33 is fixed in the clamping groove, and the projection is located in the notch, so that the motion of the sliding member 33 relative to the moving member 32 is limited. Or, the sliding member 33 can also be fixedly connected with the guide rail 312 on the guide member 31, and the moving member 32 is slidably connected with the sliding member 33. The sliding member 33 may be made of rubber, silicone or a metal material having a lower hardness than the guide member 31 and the moving member 32 .

[0051] Another example, such as Figure 4 As shown, the limiting structures 311 can be respectively provided at both ends of the guide rail 312, so as to limit the position of the moving member 32 relative to the guide member 31 through the limiting structures 311. For example, a protrusion can be provided at one end of the guide rail 312 close to the fixed end 313, and a detachable stopper can be provided at one end of the guide rail 312 away from the fixed end 313, so that the protrusion and the stopper can be used as the limiting structures 311. In this way, the sliding member 33 can be slid together with the moving member 32 from the end of the guide rail 312 away from the fixed end 313 to the guide rail 312, and then the stopper can be installed on the guide rail 312, so as to limit the sliding range of the sliding member 33 and the moving member 32 on the guide rail 312 through the stopper and the protrusion.

[0052] In another example, a power member may be provided between the moving member 32 and the guide member 31, so as to apply a force to the moving member 32 to move away from or approach the base 1. For example, a torsion spring may be provided between the moving member 32 and the guide member 31, and two torsion arms of the torsion spring may be rotationally connected to the moving member 32 and the guide member 31, respectively, so that in the process of moving the moving member 32 to move away from the base 1, the torsion spring may apply a force to the guide member 31 to move away from the base 1. Alternatively, the power member may also be a driving member capable of generating linear motion, such as an air cylinder, an oil cylinder, a linear motor, a cam, or a gear rack.

[0053] In the above embodiment, since a sliding member 33 is provided between the guide member 31 and the moving member 32, the sliding member 33 can reduce the wear of the guide member 31 and the moving member 32, which is beneficial to improving the service life of the motion mechanism 3. At the same time, a limiting structure 311 is provided on the guide member 31, and the limiting structure 311 can limit the movement position of the moving member 32 relative to the guide member 31, which is beneficial to reducing the risk of the moving member 32 detaching from the guide member 31.

[0054] In some possible embodiments of the present application, the projection host 2 is rotatably connected to the motion mechanism 3 .

[0055] In the present application embodiment, Figure 1 and Figure 2 As shown, the projection host 2 can be rotatably connected to the motion mechanism 3 so that the pitch angle of the projection host 2 can be adjusted arbitrarily.

[0056] Exemplarily, a rotating mechanism 5 can be provided between the motion mechanism 3 and the projection host 2, so that the motion mechanism 3 and the projection host 2 are rotationally connected through the rotating mechanism 5. For example, the rotating mechanism 5 can be provided as a structural form including a rotating shaft, a sleeve, an elastic member and a fastener. Among them, a screw can be adopted, and the screw is passed through the through hole as a connecting structure on the moving member 32 and connected to one end of the rotating shaft, so that the rotating shaft is fixedly connected to the moving member 32. The sleeve can be sleeved on the rotating shaft, and the elastic member can be sleeved on the rotating shaft, so that the sleeve is applied with a pressing force along the axial direction of the rotating shaft through the elastic member, and the movement of the sleeve relative to the rotating shaft in the axial direction of the rotating shaft is limited by fasteners such as C-shaped retaining rings or nuts, so that the projection host 2 can be fixedly connected with the sleeve. In this way, the force applied to the sleeve by the elastic member can make the sleeve and the rotating shaft have enough rotation resistance, so that the sleeve can stop at any position during the relative rotation of the rotating shaft, and the projection host 2 can be adjusted to any pitch angle.

[0057] Another example, such as Figure 2 As shown, the axis of rotation of the projection host 2 relative to the base 1 can be set to be perpendicular to the projection direction P of the projection host 2, or nearly perpendicular to it.

[0058] In the above embodiment, since the projection host 2 is rotatably connected to the motion mechanism 3, when the projection host 2 is moved to a position away from the base 1 by the motion mechanism 3, the projection host 2 can be rotated to adjust the pitch angle of the projection host 2, thereby facilitating the adjustment of the projection direction P of the projection device.

[0059] In some possible embodiments of the present application, a first switch component 4 is arranged between the projection host 2 and the base 1, and the first switch component 4 is electrically connected to the controller of the projection device; when the projection host 2 moves away from or close to the base 1 through the motion mechanism 3, the first switch component 4 generates a corresponding control signal.

[0060] In the present application embodiment, Figure 1 As shown, a first switch component 4 may be provided in the projection device to control the working mode of the projection device through the first switch component 4 .

[0061] For example, the first switch assembly 4 can be arranged between the projection host 2 and the base 1, such as installing a part of the first switch assembly 4 on the projection host 2, and installing another part of the first switch assembly 4 on the base 1. In this way, when the projection host 2 moves away from the base 1 through the motion mechanism 3, the two parts of the first switch assembly 4 also generate relative movement, so that the first switch assembly 4 can generate a changing signal, that is, the first switch assembly 4 can generate a first control signal; and when the projection host 2 moves toward the base 1, the first switch assembly 4 can generate a second control signal.

[0062] In another example, the first switch component 4 can be electrically connected to the controller of the projection device in a wireless or wired manner. In this way, when the first switch component 4 generates a control signal, the controller can control the projection device to enter a corresponding working mode based on the control signal. For example, when the first switch component 4 generates a first control signal, the controller can control the projection host 2 to turn on; and when the first switch component 4 generates a second control signal, the controller can control the projection host 2 to turn off.

[0063] In the above embodiment, since the first switch component 4 is provided between the projection host 2 and the base 1, and the first switch component 4 is electrically connected to the controller of the projection device, during the movement of the projection host 2 relative to the base 1, the first switch component 4 can generate a corresponding control signal, so that the projection device can be controlled by the controller to enter a corresponding working mode based on the control signal, such as turning on or off the projection host 2. In this way, while adjusting the height of the projection host 2, the working mode of the projection device can be automatically controlled, thereby saving the steps of turning on or off the projection host 2.

[0064] In some possible embodiments of the present application, the first switch component 4 includes a Hall device 41 and a magnetic component 42, one of the Hall device 41 and the magnetic component 42 is arranged on the projection host 2, the other of the Hall device 41 and the magnetic component 42 is arranged on the substrate 1, and the Hall device 41 is electrically connected to the controller of the projection device.

[0065] In the embodiment of the present application, the first switch component 4 may adopt a non-contact sensor, for example, the first switch component 4 may adopt a Hall proximity switch.

[0066] For example, Figure 1 As shown, the Hall type proximity switch can be set to a structure including a Hall device 41 and a magnetic member 42; the magnetic member 42 can be a permanent magnet, such as a magnet; the Hall device 41 can be a Hall element and a corresponding signal processing circuit. Among them, the Hall device 41 can be installed on the end of the projection host 2 close to the base 1, and the magnetic member 42 can be installed on the base 1 at a position corresponding to the Hall device 41. Alternatively, the Hall device 41 can be installed on the base 1 close to the end of the projection host 2, and the magnetic member 42 can be installed on the projection host 2 at a position corresponding to the Hall device 41. The Hall device 41 is electrically connected to the controller of the projection device through a wire.

[0067] In this way, when the projection host 2 moves toward or away from the substrate 1, the distance between the magnetic member 42 and the Hall device 41 will change, which will cause the magnetic field near the Hall device 41 to change, and the Hall device 41 will convert the change in the magnetic field into an electrical signal to input a preset control signal to the controller of the projection device. For example, when there is a preset distance between the Hall device 41 and the magnetic member 42, a preset power-on signal can be input to the controller through the Hall device 41 to turn on the projection device.

[0068] In another example, the first switch assembly 4 may also be a contact switch, which may be mounted on the base 1 or the projection host 2, and electrically connected to the controller of the projection device. When the projection host 2 moves relative to the base 1, the contact switch may be triggered to generate an electrical signal, or a preset control signal may be input to the controller.

[0069] In the above embodiment, since the first switch assembly 4 is configured to include a Hall device 41 and a magnetic member 42, the Hall device 41 and the magnetic member 42 can be respectively arranged at corresponding positions on the base 1 and the projection host 2, and an electrical signal can be generated by the Hall device 41 during the movement of the projection host 2 relative to the base 1, so that a control signal can be input to the controller of the projection device. In addition, the Hall device 41 and the magnetic member 42 are non-contact in the process of generating the electrical signal, thereby reducing the risk of failure of the first switch assembly 4 due to mechanical wear.

[0070] In some possible embodiments of the present application, an angle detection component is provided on the projection host 2, and the angle detection component is electrically connected to the controller of the projection device. The angle detection component is used to detect the deflection angle of the projection host 2 relative to the base 1, and the controller is used to control the projection mode of the projection host 2 according to the deflection angle.

[0071] In the embodiment of the present application, the projection host 2 is rotatably connected to the motion mechanism 3, and the projection host 2 can be rotated to adjust the pitch angle of the projection host 2. In this way, an angle detection member can be provided on the projection host 2 to detect the deflection angle of the projection host 2 relative to the base 1.

[0072] Exemplarily, the angle detection member may be a gyroscope, which may be installed in the projection host 2, and the gyroscope may be electrically connected to the controller of the projection device. In this way, during the rotation of the projection host 2 relative to the base 1, the gyroscope may output a corresponding electrical signal according to the detected deflection angle, and after the controller receives the electrical signal input by the gyroscope, the projection device may be controlled to execute a projection mode corresponding to the electrical signal. For example, when the angle detection member detects that the deflection angle of the projection host 2 relative to the base 1 is greater than or equal to 30 degrees, the projection host 2 may be controlled to enter a viewing mode; and when the angle detection member detects that the deflection angle of the projection host 2 relative to the base 1 is less than 30 degrees, the projection host 2 may be controlled to enter a shutdown state.

[0073] In another example, the angle detection member may also be a contact switch electrically connected to the projection device, the contact switch may be installed in the projection host 2, and a convex block corresponding to the contact switch may be provided on the rotation mechanism 5. When the projection host 2 drives the contact switch to rotate until it abuts against the convex block, the contact switch is triggered, and a preset control signal may be input to the controller.

[0074] In the above embodiment, since an angle detection component is provided on the projection host 2 and the angle detection component is electrically connected to the controller, a preset control signal can be input to the controller through the angle detection component during the process of rotating the projection host 2, so that the projection host 2 automatically enters the corresponding projection mode according to different deflection angles, which can reduce the operation steps of the projection host 2.

[0075] In some possible embodiments of the present application, a lighting component is provided on the projection host 2, and the lighting component is electrically connected to a controller of the projection device, and the controller is also used to control a lighting mode of the lighting component according to a deflection angle.

[0076] In the embodiment of the present application, a light assembly may be provided on the projection host 2, so that the projection device may have the function of an atmosphere light. For example, a plurality of light emitting diodes (LEDs) may be provided on the housing of the projection host 2 near the lens assembly, and the LEDs may be electrically connected to the controller of the projection device. For example, along the circumferential direction of the projection host 2, a circle of LEDs may be provided on the end face of the lens provided on the projection host 2, that is, a plurality of LEDs may be distributed in sequence and surround the projection device in a ring shape.

[0077] In this way, the light mode of the light assembly can be controlled according to the deflection angle of the projection host 2 relative to the base 1. For example, when the deflection angle of the projection host 2 relative to the base 1 is less than 30 degrees, the light assembly can be controlled to be in the night light mode to provide weak light illumination for the room; the light assembly can also be controlled to be in the kaleidoscope mode, that is, to produce light effects of different styles that can be changed.

[0078] In the above embodiment, since a lighting assembly is provided on the projection host 2, and the lighting assembly is electrically connected to a controller of a projection device connected to an angle detection member, the lighting assembly can be automatically controlled to enter a corresponding lighting mode according to a deflection angle of the projection host 2 relative to the base 1, which not only enables the projection device to have a lighting function, but also enables the lighting assembly to produce different lighting effects.

[0079] In some possible embodiments of the present application, the projection device also includes a second switch component 6, which is fixed on the base 1 or the projection host 2, and the second switch component 6 is electrically connected to the controller of the projection device. The second switch component 6 generates a control signal through manual control, and the controller is also used to control the lighting mode of the lighting component and / or the projection mode of the projection host 2 according to the control signal.

[0080] In the present application embodiment, Figure 2 As shown, a second switch component 6 can be provided on the projection device, and the second switch component 6 can be electrically connected to the controller of the projection device, wherein the second switch component 6 can adopt a switch manually controlled by a user, such as the second switch component 6 can select a touch switch or a contact switch, and the second switch component 6 can be touched or pressed to make the second switch component 6 generate a corresponding control signal.

[0081] Exemplarily, the second switch assembly 6 can be disposed on the base 1, such as on the support 12 of the base 1. Meanwhile, a power interface 7 can be disposed on the support 12, so that the power adapter can be plugged into the power interface 7 to power the projection device.

[0082] In this way, the working mode of the projection device can also be controlled by the second switch component 6. For example, when the projection host 2 is far away from the base 1 and the projection device is still in the off state, the power on, standby, flashing and power off of the projection device can be controlled by the second switch component 6. For example, after the projection device is powered on again or in the standby state, the second switch component 6 can be pressed short (e.g., less than 2 seconds) to turn the projection device into the power on state, or the second switch component 6 can be pressed short again to turn the projection device into the atmosphere light mode; when the projection device is in the power on, atmosphere light or viewing mode, the second switch component 6 can be pressed short to turn the projection device into the off state; or when the projection device is in the standby state, the second switch component 6 can be pressed long (e.g., greater than or equal to 6 seconds) to turn the projection device into the flashing state.

[0083] In the above embodiment, since a manually controlled second switch component 6 is provided on the projection device, when the first switch component 4 cannot control the projection device to enter a corresponding working mode, the working mode of the projection device can be controlled by the second switch component 6.

[0084] In some possible embodiments of the present application, the projection device further includes an audio component electrically connected to the controller, the base 1 has a receiving cavity, and the controller and / or the audio component is installed in the receiving cavity.

[0085] In the embodiment of the present application, an audio component may be provided in the projection device, and the audio component may be electrically connected to a controller of the projection device so as to output sound through the audio component.

[0086] For example, a receiving cavity may be provided in the base 1, for example, a cavity serving as the receiving cavity may be provided in the base 11 of the base 1. Then, the audio component, the controller of the projection device and other devices in the projection device may be installed in the receiving cavity.

[0087] In the above embodiment, since the accommodating cavity is provided on the base 1, the accommodating cavity can provide an installation space for the audio component and / or the controller of the projection device, so as to facilitate the installation of the audio component, the controller, etc. in the projection device.
