[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] Laser projection TV mainly includes two parts: laser projector and screen. The laser projector mainly includes a housing and components such as a lens disposed in the housing. An opening opposite to the lens is provided on the housing so that the lens can project images onto the screen through the opening. In order to prevent dust and impurities from entering the housing and adhering to the lens when the laser projection TV is not in use, the opening on the housing can be opened and closed.

[0050] At present, the opening and closing of the shell of laser TV is mainly realized by a detachable baffle, which requires the user to manually remove and install the baffle to open and close the opening, making the operation of laser projection TV cumbersome. In addition, when the user forgets to install the baffle on the opening of the shell, it will further increase the risk of dust and impurities entering the shell and adhering to the lens.

[0051] In the display device proposed in the embodiment of the present application, the display body is arranged in the cavity of the shell, so that the shell can play the purpose of protecting the display body, and the display body can project the picture outward through the opening of the shell. The cover plate is rotatably arranged on the shell so that the cover plate can rotate around the rotation connection between the cover plate and the shell, so that the rotation range of the cover plate during the rotation relative to the shell is relatively small, so that the display device of the present application has a relatively compact structure under various use conditions. The driving part in the driving assembly drives the connecting rod to reciprocate in a preset direction, and the connecting rod is rotatably connected to the driving part. The driving force of the driving part is converted into a rotational force to rotate the connecting rod, so that the connecting rod flips, so that the connecting rod can drive the cover plate to flip relative to the shell, so that the cover plate can rotate to close the opening of the shell or open the opening of the shell, thereby realizing the opening and closing of the shell. In this way, there is no need to manually apply force to the cover plate to open and close the opening of the shell, so that the opening and closing process of the shell is simple and convenient.

[0052] The present application embodiment provides a display device, referring to Figures 1 to 3As shown, the display device includes a housing 100. The housing 100 is a basic component of the display device of the present application. The housing 100 can provide a mounting base for at least some of the other components of the display device and protect at least some of the other components. The housing 100 can be made of a metal material, so that the housing 100 has a better structural strength, thereby making the durability and reliability of the housing 100 better. Of course, the housing 100 can also be made of a polymer material, so that the housing 100 has a better structural strength and is relatively light, which can make the weight of the display device lighter.

[0053] The housing 100 has a cavity 110 and an opening 120 communicating with the cavity 110, wherein the cavity 110 of the housing 100 is an inner cavity structure of the housing 100, and the opening 120 of the housing 100 is disposed on the surface of the housing 100, and the cavity 110 of the housing 100 can be communicated with the outside of the housing 100 through the opening 120. The cavity 110 of the housing 100 can be used to install at least part of other components of the display device.

[0054] The display device also includes a display body (not shown in the figure), which is arranged in the housing 100. When the display device of the present application is a projection device, the display body is a projector, and the display device can project light onto a wall or a screen to form a picture. The display body can have a projection end, which is specifically a lens of the display body, and the display body projects the picture onto the screen through the projection end. The projection end of the display body can face the opening 120 of the housing 100, so that the light emitted by the projection end of the display body can pass through the opening 120 and be projected onto the screen.

[0055] The display device further includes a cover plate 200, which is rotatably connected to the housing 100, so that the cover plate 200 can rotate relative to the housing 100. Specifically, the cover plate 200 can rotate relative to the housing 100 to cover the opening 120 of the housing 100, or rotate to separate from the opening 120 of the housing 100, so as to open and close the opening 120 of the housing 100 through the cover plate 200. When the display device is in use, the cover plate 200 can be controlled to rotate to separate from the opening 120 of the housing 100, so that the projection end of the display body can project an image to the screen through the opening 120. When the display device is not in use, the cover plate 200 can be controlled to rotate to cover the opening 120 of the housing 100, so that the cover plate 200 closes the opening 120 of the housing 100. In this way, external dust and impurities will not enter the housing 100 through the opening 120, thereby protecting the display body.

[0056] In addition, the rotatable connection between the cover plate 200 and the shell 100 also allows the cover plate 200 to always rotate around the rotational connection between the cover plate 200 and the shell 100 when the cover plate 200 rotates relative to the cover plate 200. In this way, the rotation center of the cover plate 200 remains unchanged, so that the range of movement of the cover plate 200 during the rotation process is relatively small, thereby allowing the display device of the present application to maintain a compact structure in a variety of usage conditions.

[0057] Continue to refer Figures 3 to 6 As shown, the display device further includes a driving assembly 300, and the driving assembly 300 is used to drive the cover plate 200 and the housing 100 to rotate relative to each other, so that the cover plate 200 can open and close the opening 120 of the housing 100. The driving assembly 300 includes a driving part 310 and a connecting rod 320, wherein the driving part 310 can be disposed on the housing 100 so that the driving part 310 can be fixed, and the connecting rod 320 has a first end 321 and a second end 322, and the first end 321 and the second end 322 of the connecting rod 320 are opposite ends of the connecting rod 320. The first end 321 of the connecting rod 320 can be rotatably connected to the cover plate 200, and the second end 322 of the connecting rod 320 can be rotatably connected to the driving part 310, so that the two ends of the connecting rod 320 can rotate relative to the cover plate 200 and the driving part 310, respectively. The driving part 310 can drive the second end 322 of the connecting rod 320 to rotate along a preset direction ( Figure 6 The connecting rod 320 reciprocates in the X direction (in the X direction), and since the first end 321 of the connecting rod 320 is rotatably connected to the cover plate 200, the connecting rod 320 can convert the force applied by the driving unit 310 to move in a preset direction into a rotational force for driving the cover plate 200 to rotate relative to the shell 100, so that the connecting rod 320 can drive the cover plate 200 to rotate relative to the shell 100, so that the cover plate 200 can open and close the opening 120 of the shell 100.

[0058] Specifically, when the driving unit 310 drives the second end 322 of the connecting rod 320 to move in a preset direction, the cover plate 200 can be driven to rotate relative to the housing 100 to separate from the opening 120 of the housing 100, so that the opening 120 of the housing 100 is opened. When the driving unit 310 drives the second end 322 of the connecting rod 320 to move in a direction opposite to the preset direction, the cover plate 200 can be driven to rotate relative to the housing 100 to cover the opening 120 of the housing 100, so that the opening 120 of the housing 100 is closed.

[0059] Therefore, the driving assembly 300 in the present application can directly drive the cover plate 200 through the connecting rod 320 to rotate the cover plate 200 relative to the housing 100, so that the driving assembly 300 will not directly act on the rotational connection between the cover plate 200 and the housing 100, so that the number of types of forces applied to the rotational connection between the cover plate 200 and the housing 100 is relatively less, and the magnitude of the applied forces is relatively smaller, thereby achieving the purpose of protecting the rotational connection between the cover plate 200 and the housing 100. In this way, after the display device of the present application is used for a long time, the rotational connection effect between the cover plate 200 and the housing 100 can also be maintained well, so that after the cover plate 200 opens and closes the opening 120 of the housing 100 for many times, the cover plate 200 can still rotate smoothly relative to the housing 100.

[0060] In some embodiments, reference Figure 6 As shown, the cover plate 200 of the present application has an opening and closing surface 210. When the cover plate 200 covers the opening 120 of the housing 100, the opening and closing surface 210 of the cover plate 200 is opposite to the opening 120 of the housing 100, so that the opening and closing surface 210 of the cover plate 200 can close the opening 120 of the housing 100. The first end 321 of the connecting rod 320 can be rotatably connected to the opening and closing surface 210 of the cover plate 200, so that when the driving part 310 drives the first end 321 of the connecting rod 320 to reciprocate along a preset direction, the second end 322 of the connecting rod 320 can directly act on the opening and closing surface 210 of the cover plate 200, so that the cover plate 200 is more fully stressed, so that the cover plate 200 can rotate more smoothly relative to the housing 100. The housing 100 has a mounting surface 130 , which is the surface of the housing 100 . The opening 120 of the housing 100 is disposed on the mounting surface 130 of the housing 100 . The driving unit 310 may be disposed in the housing 100 and below the mounting surface 130 .

[0061] Accordingly, since the second end 322 of the connecting rod 320 is rotatably connected to the driving part 310, the second end 322 of the connecting rod 320 is also located below the mounting surface 130, so that the distance between the first end 321 and the second end 322 of the connecting rod 320 is relatively small, so that the length of the connecting rod 320 is relatively short, and finally the structure of the display device of the present application is relatively more compact. In addition, the driving part 310 is arranged in the housing 100 and is located below the mounting surface 130, and the space in the housing 100 can be fully utilized, and the driving part 310 is protected by the housing 100 to avoid exposure of the driving part 310, so that the display device of the present application is more beautiful.

[0062] In some embodiments, reference Figure 3As shown, the mounting surface 130 of the housing 100 in the present application is located at the top of the housing 100, and correspondingly, the opening 120 of the housing 100 is also located at the top of the housing 100, and the display body can project images onto the screen through the opening 120 at the top of the housing 100. It should be understood that the screen adapted to the display device of the present application can be set at a position higher than the housing 100, such as the display device can be placed on a relatively low desktop, and the display body projects images onto the screen through the opening 120 at the top of the housing 100, so that the display device of the present application is more in line with the user's usage habits.

[0063] In some embodiments, reference Figures 6 to 8 As shown, the driving part 310 of the present application can be configured to include a driver 311, a transmission gear 312 and a transmission rack 313. The driver 311 can be disposed on the housing 100, the transmission gear 312 is connected to the output end of the driver 311, and the driver 311 can drive the transmission gear 312 to rotate. The transmission rack 313 is movably disposed on the housing 100, and the transmission rack 313 is meshed with the transmission gear 312. When the driver 311 drives the transmission gear 312 to rotate, the transmission rack 313 can be driven to move, wherein the moving direction of the transmission rack 313 is reciprocating along a preset direction, and the second end 322 of the connecting rod 320 can be rotatably connected to the transmission rack 313, and when the transmission rack 313 reciprocates along the preset direction, the second end 322 of the connecting rod 320 can be driven to reciprocate along the preset direction.

[0064] Specifically, the length direction of the transmission rack 313 is in the same direction as the preset direction. When the driver 311 drives the transmission gear 312 to rotate forward and reverse, the transmission gear 312 cooperates with the transmission rack 313 to convert the rotational force output by the driver 311 into a force that drives the transmission rack 313 to move back and forth in the preset direction, so that the second end 322 of the connecting rod 320 can also move back and forth in the preset direction. The driver 311 can specifically use a motor, and the overall structure of the transmission structure in which the transmission gear 312 cooperates with the transmission rack 313 is relatively simple, the cost is relatively low, and the later maintenance and repair are relatively convenient, so that the cost of the display device of the present application can be relatively low.

[0065] In some embodiments, reference Figure 7 and Figure 8As shown, the driving assembly 300 of the present application may also be provided with a guide portion 314, which is provided on the housing 100, and is connected to the transmission rack 313, and the guide portion 314 is also connected to the second end 322 of the connecting rod 320. When the transmission rack 313 in the driving part 310 reciprocates along the preset direction, since the guide portion 314 is connected to the transmission rack 313, the guide portion 314 can also reciprocate along the preset direction with the transmission rack 313. The guide portion 314 serves to limit the moving direction of the transmission rack 313, so that the transmission rack 313 can only reciprocate along the preset direction, thereby preventing the transmission rack 313 from being deflected during the movement process.

[0066] In addition, the transmission rack 313 is connected to the shell 100 through the guide portion 314 to realize the movable connection between the transmission rack 313 and the shell 100. In this way, there is no need to separately set up the transmission rack 313 to be connected to the shell 100. Accordingly, there is no need to additionally set up a structure on the transmission rack 313 for movably connecting the transmission rack 313 to the shell 100, so that the structure of the transmission rack 313 is relatively simple, the difficulty of preparing the transmission rack 313 is reduced, and the number of components of the display device of the present application can be reduced.

[0067] In some embodiments, the guide portion 314 in the present application may specifically include a guide block 3141 and a guide rail 3142, wherein the guide rail 3142 is disposed on the housing 100 and is disposed along a preset direction. The guide block 3141 is slidably connected to the guide rail 3142, so that the guide block 3141 can slide along the setting direction of the guide rail 3142, i.e., the preset direction. The transmission rack 313 is connected to the guide block 3141, so that after the transmission gear 312 drives the transmission rack 313 to move, the transmission rack 313 can drive the guide block 3141 to slide along the guide rail 3142. The second end 322 of the connecting rod 320 is rotatably connected to the guide block 3141, and when the guide block 3141 reciprocates along the preset direction, it can drive the second end 322 of the connecting rod 320 to reciprocate along the preset direction, so that the connecting rod 320 can drive the cover plate 200 to flip relative to the housing 100 to open and close the opening 120 of the housing 100.

[0068] The guide rail 3142 can be a metal guide rail 3142, and the guide block 3141 can also be a metal piece, which can make the guide rail 3142 and the guide block 3141 have better structural strength, durability and reliability. Of course, the guide rail 3142 can also be a guide groove structure opened on the housing 100, and the guide block 3141 can be slidably embedded in the guide groove, which can also make the guide part 314 have a guiding function.

[0069] In some embodiments, reference Figure 6 and Figure 7As shown, in the present application, the preset direction in which the second end 322 of the connecting rod 320 is driven by the driving unit 310 to move is parallel to the mounting surface 130 of the housing 100. Accordingly, the second end 322 of the connecting rod 320 can always remain parallel to the mounting surface 130 when reciprocating along the preset direction, so that the space occupied in the height direction during the process of the driving unit 310 driving the second end 322 of the connecting rod 320 to move remains unchanged, so that the structure of the driving unit 310 can always remain compact in the height direction during the process of the driving unit 310 driving the connecting rod 320 to move, so that the display device of the present application can maintain a compact structure in various usage states.

[0070] In some embodiments, reference Figure 6 and Figure 7 As shown, the axis of the transmission gear 312 in the driving part 310 of the present application can be set to be perpendicular to the mounting surface 130 of the shell 100, so that the transmission gear 312 can be horizontally set on the mounting surface 130. In this way, the space occupied by the transmission gear 312 in the height direction is relatively smaller, thereby making the structure of the driving part 310 relatively more compact.

[0071] In some embodiments, reference Figure 6 and Figure 7 As shown, the driving assembly 300 of the present application may also be provided with a detection unit 330, wherein the detection unit 330 is provided on the housing 100, and the detection unit 330 is configured to detect the movement stroke of the second end 322 of the connecting rod 320. It should be understood that in the present application, the angle of rotation of the cover plate 200 relative to the housing 100 is determined by the movement stroke of the second end 322 of the connecting rod 320 driven by the driving unit 310. When the cover plate 200 rotates to close the opening 120 of the housing 100, the driving unit 310 has a corresponding position, and when the cover plate 200 rotates to open the opening 120 of the housing 100 to the maximum extent, the driving unit 310 has another corresponding position, so the angle of rotation of the cover plate 200 relative to the housing 100 can be limited by limiting the movement stroke of the driving unit 310. Among them, the detection unit 330 is also electrically connected to the driving unit 310, and can be specifically electrically connected to the driver 311 in the driving unit 310. When the detection unit 330 detects that the driving unit 310 moves to a position corresponding to the opening 120 where the cover 200 covers the shell 100, the detection unit 330 can send a signal to the driver 311 so that the driver 311 no longer drives the transmission gear 312 to rotate, so that the cover 200 will not continue to rotate, thereby protecting the driver 311 and preventing the driver 311 from being damaged.

[0072] In addition, it can be arranged that when the detection unit 330 detects that the driving unit 310 moves to a position corresponding to the cover plate 200 opening the opening 120 of the shell 100 to the maximum extent, the detection unit 330 sends a signal to the driver 311 so that the driver 311 no longer drives the transmission gear 312 to rotate, thereby preventing the cover plate 200 from excessively rotating and causing damage to the cover plate 200, the shell 100 and the connecting rod 320, so as to protect the cover plate 200, the shell 100 and the connecting rod 320.

[0073] In the present application, the detection unit 330 may be specifically configured to include a pressure sensor 331 and a baffle 332. The pressure sensor 331 may be disposed on the housing 100, and the baffle 332 may be disposed on the guide block 314 of the driving unit 310, so that the baffle 332 may move with the guide block 314. When the housing 100 rotates to cover the opening 120 of the housing 100, the baffle 332 may move to contact the pressure sensor 331, and the baffle 332 generates a force on the pressure sensor 331. The pressure sensor 331 detects a pressure change, so that the pressure sensor 331 detects a signal to control the driver 311 to stop driving the transmission gear 312 to rotate.

[0074] The detection part 330 may also be provided with a plurality of baffles 332, and another baffle 332 may be provided on the guide block 314 of the driving part 310, so that the other baffle 332 may move with the guide block 314. When the housing 100 rotates to open the opening 120 of the housing 100 to the maximum extent, the other baffle 332 may move to contact the pressure sensor 331, so that the pressure sensor 331 detects a signal to control the driver 311 to stop driving the transmission gear 312 to rotate, so that the cover plate 200 can maintain the state of opening the opening 120 of the housing 100 to the maximum extent.

[0075] In some embodiments, reference Figure 3 As shown, the number of drive assemblies 300 in the present application can be set to two, and the two drive assemblies 300 can be symmetrically arranged on both sides of the opening 120 of the shell 100, and the first ends 321 of the connecting rods 320 in the two drive assemblies 300 can be rotatably connected to different parts of the cover plate 200, so that the force on the cover plate 200 is more balanced, so that the cover plate 200 is more stable when rotating relative to the shell 100.

[0076] Of course, the number of drive assemblies 300 may be more than two. The more drive assemblies 300 there are, the more stable and reliable the cover 200 is when rotating relative to the shell 100. This application does not limit the specific number of drive assemblies 300.

[0077] In some embodiments, the driving assembly 300 in the present application may also be electrically connected to the display body. Specifically, the display body may be electrically connected to the driver 311 in the driving assembly 300. When the display body receives a power-on command, the driver 311 may be activated to drive the cover plate 200 to rotate relative to the housing 100 to open the opening 120 of the housing 100. When the display body receives a power-off command, the driver 311 may be activated to drive the cover plate 200 to rotate relative to the housing 100 to close the opening 120 of the housing 100.

[0078] In some embodiments, reference Figure 1 , Figure 2 , Figure 3 , Fig. 9 and Fig.10 As shown, the cover plate 200 can be provided with various external shapes and structures as required, and the cover plate 200 only needs to be able to open and close the opening 120 of the housing 100 .
