[0040] A laser TV is a projection display device that uses a laser light source. It is typically equipped with a short-throw lens, enabling it to project a large image from a very short distance. However, the light-emitting glass of existing laser TV lenses is mostly exposed, making them prone to dust accumulation and susceptible to damage from impacts, thus affecting the projection quality of the laser TV.
[0041] Therefore, this application provides a laser TV. By providing a retractable sliding cover at the light output port of the laser TV, the light output port can be opened or closed. When the laser TV is on, the sliding cover opens the light output port to ensure the normal use of the laser TV. When the laser TV is off, the sliding cover closes the light output port, effectively blocking the light output glass of the lens, preventing dust from falling on the light output glass, and protecting the lens.
[0042] In some embodiments, refer to Figures 1 to 8 As shown, this application provides a laser TV, including: a housing 1, a lens 2, and a sliding cover assembly 3. The housing 1 has a recessed light-guiding region 4 at its top, and a light-emitting port 5 at its bottom. The lens 2 is disposed within the housing 1 and includes a light-emitting glass 6 facing the light-emitting port 5. The sliding cover assembly 3 includes a sliding cover 7 disposed within the housing 1 and a driving mechanism 8. The sliding cover 7 is adjacent to the light-emitting port 5, and the driving mechanism 8 is connected to the sliding cover 7 to drive the sliding cover 7 to extend and retract at the light-emitting port 5, thereby opening or closing the light-emitting port 5.
[0043] The housing 1 is the main structure of the laser TV and can be made of plastics such as ABS (acrylonitrile-butadiene-styrene copolymer) and PC (polycarbonate), or metal materials such as aluminum alloy and stainless steel. The shape of housing 1 can be cuboid, sphere, cylinder, etc. Optionally, such as... Figure 2 and Figure 3 As shown, the housing 1 may include an upper housing 9 and a lower housing 10. The upper housing 9 covers the lower housing 10 to enclose a hollow cavity for accommodating the various components. The upper housing 9 at the top is designed with a downwardly recessed area, namely the light guiding area 4, and a light outlet 5 is provided at the bottom of this area, which is where the light is projected.
[0044] The light-guiding area 4 is a recessed portion of the top upper shell 9 of the housing 1. Its main function is to guide the light projected from the lens 2 and direct it to the display screen. Optionally, the cross-sectional area of the light-guiding area 4 gradually increases along the direction from the bottom light outlet 5 to the top upper shell 9. This gradually expanding structural design can widen the range of light projection angles, allowing the light emitted from the bottom light outlet 5 to diffuse more evenly during propagation, improving display uniformity and thus effectively enhancing the projection effect. As an example, such as... Figure 1 and Figure 2 As shown, the light guiding area 4 can be integrally formed by recessing the upper shell 9 downwards. The light guiding area 4 can include four enclosing sidewalls 11. The four sidewalls 11 are designed to gradually expand around the light outlet 5, thereby forming a light guiding area 4 with openings at both ends.
[0045] like Figure 3 and Figure 4As shown, lens 2 is installed inside housing 1 and includes light-emitting glass 6. Light-emitting glass 6, as part of lens 2, faces directly towards light-emitting port 5 and is responsible for allowing light to pass through and be projected out. The function of lens 2 is to focus the laser beam and project it onto the display screen through light-emitting glass 6 and light-emitting port 5 via light guide area 4 to form an image.
[0046] In the sliding cover assembly 3, the sliding cover 7 is located adjacent to the light exit port 5 and can slide and extend at the light exit port 5 under the driving force of the drive mechanism 8 to open or close the light exit port 5. This helps to protect the light exit glass 6 of the internal lens 2.
[0047] Power-on state: When the laser TV is turned on, the drive mechanism 8 drives the sliding cover 7 to retract into the housing 1, opening the light outlet 5. At this time, the laser beam generated by the laser light source of the laser TV is projected onto the lens 2, passes through the light-emitting glass 6 and the light outlet 5, and is then guided by the light guide area 4 to finally be projected onto the display screen to form a clear image.
[0048] Power-off state: When the laser TV is turned off, in order to protect the light-emitting glass 6 from damage caused by dust accumulation and external impacts, the drive mechanism 8 drives the sliding cover 7 to extend onto the light-emitting port 5 to seal it. This effectively prevents dust accumulation and impacts from damaging the light-emitting glass 6, ensuring that the picture quality will not be affected during the next use.
[0049] Therefore, the laser TV provided in this application solves the problem of easy damage to the light-emitting glass 6 of the lens 2 in existing laser TVs by introducing a sliding cover assembly 3, which not only ensures the normal use of the device, but also improves the durability of the device.
[0050] In some embodiments, refer to Figures 4 to 6 As shown, the drive mechanism 8 includes a motor 12 and a transmission component. The motor 12 is fixed inside the housing 1, and the output shaft of the motor 12 is connected to the sliding cover 7 via the transmission component.
[0051] The specific type of transmission component in this application is not particularly limited. Optionally, the transmission component can be a synchronous belt, which connects the output shaft of the motor 12 and the sliding cover 7. The rotation of the motor 12 drives the synchronous belt to move, thereby pushing or pulling the sliding cover 7 to open and close. This method has the advantages of low noise and smooth operation. Alternatively, the transmission component can also be a lead screw, which is driven by the motor 12 to rotate. The nut on the lead screw is connected to the sliding cover 7. As the lead screw rotates, the nut moves along the axial direction of the lead screw, thereby driving the sliding cover 7 to slide. This transmission method has high precision.
[0052] As an example, the transmission component may also include a gear 13 and a rack 14. The gear 13 is connected to the output shaft of the motor 12, and the rack 14 can be mounted on the slide cover 7 by fasteners 20 such as screws and extends along the sliding direction X of the slide cover 7, and the rack 14 meshes with the gear 13. When the motor 12 rotates, the rotational motion is converted into the linear motion of the slide cover 7 through the engagement of the gear 13 and the rack 14.
[0053] Power-on state: When the laser TV is turned on, the motor 12 starts to run. Through any of the above-mentioned transmission components, the rotational motion of the motor 12 is converted into the linear motion of the sliding cover 7, causing it to slide and open the light outlet 5 so that light can be projected out through the light outlet glass 6 of the lens 2.
[0054] Power off state: Once a power off command is received, motor 12 rotates in the reverse direction. Similarly, through the action of the transmission component, the sliding cover 7 slides in the reverse direction until it completely covers the light outlet 5, protecting the light outlet glass 6 of lens 2 from dust and external physical damage.
[0055] In some embodiments, refer to Figures 2 to 6 As shown, the plane where the light outlet 5 is located has an angle α with the horizontal plane; the sliding cover assembly 3 also includes a mounting bracket 15 disposed in the housing 1. The mounting bracket 15 includes a mounting part 16, which is parallel to the plane where the light outlet 5 is located. The sliding cover 7 is telescopically and slidably disposed on the mounting part 16 and is parallel to the mounting part 16. The motor 12 is fixed on the mounting part 16.
[0056] The plane where the light outlet 5 is located is tilted at a certain angle to the horizontal plane. This helps to adjust the angle of light projection, so that the light can be projected onto the display screen on the wall more accurately. Especially in the application scenario of short-throw lenses, it can effectively improve the picture quality and reduce image distortion.
[0057] Mounting bracket 15 includes a mounting section 16, which is parallel to the inclined plane of the light outlet 5. This design allows the entire sliding cover assembly to be fitted and installed according to the inclined direction of the light outlet 5.
[0058] The sliding cover 7 is mounted on the mounting part 16 and is parallel to the mounting part 16. This means that the sliding cover 7 is also arranged at the same tilt angle to ensure that it can match the position of the light outlet 5 when it is opened or closed, thereby realizing the effective opening and closing of the light outlet 5.
[0059] The motor 12 is directly fixed to the mounting part 16, providing power for the opening and closing of the sliding cover 7. By integrating key components such as the sliding cover 7 and the motor 12 into a single mounting part 16, the entire assembly becomes more compact, reducing unnecessary space waste. At the same time, this modular design greatly simplifies later maintenance; if a component needs to be replaced or repaired, the relevant module can be operated directly without affecting the function of other parts.
[0060] Therefore, by cleverly utilizing the mounting bracket 15, this embodiment of the application achieves a precise fit between the sliding cover 7 and the light outlet 5, which can ensure the smoothness and reliability of the device during operation.
[0061] In some embodiments, refer to Figure 5 and Figure 6 As shown, the mounting part 16 has a mounting port 17, and the motor 12 and gear 13 are embedded in the mounting port 17.
[0062] Mounting port 17 is an opening structure that penetrates the mounting part 16. The motor 12 and gear 13 can be quickly positioned and installed through mounting port 17. By embedding the motor 12 and gear 13 into mounting port 17, the space occupied by these components in the housing 1 can be reduced, making the overall structure more compact and conducive to the miniaturization design of the whole machine.
[0063] In some embodiments, refer to Figure 5 and Figure 6 As shown, the sliding cover assembly 3 also includes a guide mechanism, which includes a slide rail 18 and a slide table 19 disposed between the mounting part 16 and the sliding cover 7. The slide rail 18 is fixed on the mounting part 16 and parallel to the rack 14. The slide table 19 is slidably connected to the slide rail 18, and the sliding cover 7 is fixedly connected to the slide table 19.
[0064] The slide rail 18 can be fixed to the mounting part 16 by fasteners 20 such as screws, and remains parallel to the rack 14. The slide rail 18 provides the basic track for the movement of the slide table 19, thereby ensuring that the slide cover 7 moves linearly along the sliding direction X.
[0065] The slide table 19 is a transmission component that is slidably connected to the slide rail 18. It can slide on the slide rail 18, thereby driving the slide cover 7 connected to it to move together.
[0066] The sliding cover 7 can be directly fixed to the slide table 19 using fasteners such as screws 20, and the slide table 19 can drive the sliding cover 7 to move synchronously. This design ensures that the sliding cover 7 can smoothly open and close the light outlet 5, avoiding unnecessary offset or jamming.
[0067] Power-on state: When the laser TV is turned on, the motor 12 drives the gear 13 to rotate. The gear 13 meshes with the rack 14 to push the slide table 19 to move along the slide rail 18, thereby opening the light outlet 5 of the sliding cover 7. Due to the presence of the slide rail 18, the sliding cover 7 can move smoothly and precisely to the designated position, ensuring that light is projected out through the light outlet 5 without obstruction.
[0068] Power off state: When the device is off, the motor 12 reverses its drive, causing the sliding cover 7 to return to its original position along the slide rail 18 and completely block the light outlet 5, protecting the light outlet glass 6 of the internal lens 2 from dust and physical damage.
[0069] Therefore, by introducing a guide mechanism, the linear motion accuracy of the sliding cover 7 can be improved in this embodiment, avoiding operational instability caused by motion deviation, and reducing friction, making the opening and closing process of the sliding cover 7 smoother.
[0070] In some embodiments, refer to Figure 5 and Figure 6 As shown, the slide rail 18 and the slide table 19 are located on the central axis of the sliding cover 7 along the sliding direction X.
[0071] By arranging the slide rail 18 and the slide table 19 on the central axis of the slide cover 7, the shaking, tilting or jamming caused by uneven force during the movement of the slide cover 7 can be reduced, thereby ensuring the smooth movement of the slide cover 7 and improving the operating accuracy and smoothness of the slide cover 7.
[0072] In some embodiments, refer to Figure 4 and Figure 5 As shown, the sliding cover 7 is provided with a first limiting part 21 on one side adjacent to the mounting part 16; the mounting bracket 15 also includes two second limiting parts 22, which are respectively provided on opposite sides of the mounting part 16 and located on the sliding path of the first limiting part 21, with the first limiting part 21 stopping between the two second limiting parts 22.
[0073] The first limiting part 21 is located on the side of the sliding cover 7 adjacent to the mounting part 16. The main function of this part is to interact with the second limiting part 22 on the mounting part 16 when the sliding cover 7 is opening and closing, thereby limiting the maximum range of movement of the sliding cover 7.
[0074] Two second limiting parts 22 can be respectively provided on opposite sides of the mounting part 16 along its length, and their positions are located on the sliding path of the first limiting part 21. When the sliding cover 7 moves along the slide rail 18, the first limiting part 21 will contact one of the second limiting parts 22 at a specific point, thereby stopping further movement.
[0075] Power-on state: When the laser TV is turned on, the motor 12 drives the sliding cover 7 to retract into the housing 1 along the slide rail 18 to open the light outlet 5. When the sliding cover 7 is fully open to the light outlet 5, the first limiting part 21 on the sliding cover 7 contacts and stops the second limiting part 22 on the side away from the light outlet 5, preventing the sliding cover 7 from continuing to retract and ensuring that the sliding cover 7 will not disengage from the slide rail 18 or collide with other internal components due to excessive movement.
[0076] Power off state: When the device is off, the motor 12 drives the sliding cover 7 to extend in reverse to block the light outlet 5. Similarly, when the sliding cover 7 completely closes the light outlet 5, the first limiting part 21 on the sliding cover 7 will contact the second limiting part 22 on the other side to prevent the sliding cover 7 from extending too far and ensure that the sliding cover 7 can fit tightly against the light outlet 5.
[0077] Therefore, through the cooperation of the aforementioned limiting part, the embodiments of this application can effectively control the telescopic movement of the sliding cover 7, thereby improving the reliability of the device.
[0078] In some embodiments, refer to Figures 4 to 7 As shown, the mounting bracket 15 also includes two hook parts 23. The two hook parts 23 are respectively provided on opposite sides of the mounting part 16 along the sliding direction X of the sliding cover 7, and are hooked to the top of the housing 1, so that an avoidance channel 24 is formed between the mounting part 16 and the top of the housing 1, and the sliding cover 7 can slide in and out within the avoidance channel 24.
[0079] The two mounting parts 23 are located on opposite sides of the mounting part 16 along the sliding direction X of the sliding cover 7, that is, on... Figure 5 The mounting bracket 15 is located on opposite sides in the width direction of the mounting portion 16 and can be detachably attached to the inner wall of the upper shell 9 on the top of the housing 1 using fasteners such as screws. This design ensures a stable connection between the mounting bracket 15 and the housing 1, thereby guaranteeing the overall stability of the sliding cover assembly 3 and reducing the risk of loosening or misalignment due to vibration or external impact. Furthermore, the design of the attachment portion 23 allows the mounting bracket 15 to be quickly attached to the housing 1, simplifying the assembly process. If maintenance or replacement of the sliding cover assembly 3 is required, the entire assembly can be easily removed by simply disassembling the attachment portion 23, reducing maintenance difficulty.
[0080] Furthermore, the design of the mounting part 23 creates a specific space, namely the clearance channel 24, between the mounting part 16 and the upper shell 9 at the top of the housing 1. The clearance channel 24 provides sufficient movement space for the sliding cover 7, ensuring that the sliding cover 7 is not interfered with by the mounting bracket 15 during its extension and retraction, thereby guaranteeing the smoothness and reliability of the sliding cover 7's movement. It can be understood that the design of the mounting part 23 makes full use of the space at the top of the housing 1. By forming the clearance channel 24, the functional requirements of the sliding cover assembly 3 are achieved within a limited space, contributing to a compact design.
[0081] Therefore, by introducing the hook part 23 and forming the avoidance channel 24, the present application embodiment not only ensures the smooth movement of the sliding cover 7, but also enhances the stability of the overall structure, while simplifying the assembly and maintenance process.
[0082] In some embodiments, refer to Figure 2 and Figure 8 As shown, the light outlet 5 is provided with a first flange portion 25 on each of the opposite sides of the sliding cover 7 along the sliding direction X, and / or the light outlet 5 has a mating side 26 for the sliding cover 7 to slide into, and a second flange portion 27 is provided on the opposite side of the light outlet 5 away from the mating side 26. The first flange portion 25 and the second flange portion 27 are used to support the sliding cover 7.
[0083] The light outlet 5 is provided with first flange portions 25 on opposite sides of the sliding direction X of the sliding cover 7. These flange portions are located on both sides of the sliding path of the sliding cover 7, and their main function is to provide lateral support for the sliding cover 7 and prevent the sliding cover 7 from shifting laterally or tilting during movement.
[0084] A second flange 27 is provided on the opposite side of the light outlet 5 away from the docking side 26. The second flange 27 is mainly used to provide rear support when the sliding cover 7 is fully closed, so as to ensure that the sliding cover 7 can stay stably in the closed position and avoid the sliding cover 7 from moving accidentally due to external vibration or other reasons.
[0085] It is understandable that the mating side 26 is the side where the sliding cover 7 slides into the light outlet 5. That is, the sliding cover 7 can slide into this mating side 26 and eventually cover the entire light outlet 5, or retract into the housing 1 through this mating side 26 to open the light outlet 5. The design of the mating side 26 ensures that the sliding cover 7 can slide smoothly at the light outlet 5.
[0086] Optionally, such as Figure 2 and Figure 8 As shown, the light-emitting port 5 is roughly square. Except for the mating side 26, the other three sides of the light-emitting port 5 are provided with enclosing and connecting first flange portions 25 and second flange portions 27. The second flange portion 27 connects between the two first flange portions 25 to form an opening on the mating side 26 for easy access of the sliding cover 7. By rationally arranging these flange portions around the light-emitting port 5, support can be provided for the sliding cover 7, ensuring that when the laser TV is turned off, the sliding cover 7 can tightly fit against the light-emitting port 5, thereby providing good sealing and stability.
[0087] In some embodiments, refer to Figure 8 As shown, a sealing gasket (not shown in the figure) is provided on the first flange portion 25 and the second flange portion 27, or the sliding cover 7 is provided with a sealing gasket on the bottom surface corresponding to the first flange portion 25 and the second flange portion 27.
[0088] The sealing gasket can be disposed on the first flange 25 and the second flange 27, or on the bottom surface of the sliding cover 7 corresponding to these flanges. The function of the sealing gasket is to provide additional elastic cushioning and sealing effect when the sliding cover 7 is closed. The sealing gasket can be made of a soft and elastic material, such as silicone or rubber.
[0089] When the sliding cover 7 slides onto the first flange 25 and the second flange 27 to close the light outlet 5, the sealing gasket is compressed under the pressure of the sliding cover 7. The compressed sealing gasket fills the gap between the sliding cover 7 and the flange, thus forming a tighter sealing layer. This design can effectively prevent dust, moisture or other external contaminants from entering the laser TV, thereby protecting components such as the lens 2 and the light-emitting glass 6 from contamination or damage.
[0090] Therefore, this embodiment of the application further optimizes the sealing performance of the sliding cover assembly 3 by setting a sealing gasket. This design not only improves the protection capability of the laser TV, but also significantly improves the product's reliability and user experience.
[0091] The above are merely preferred embodiments of this application and are not intended to limit the embodiments of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the embodiments of this application should be included within the protection scope of the embodiments of this application.
