Description

Technical Field

[0001] This application relates to the field of liquid crystal display manufacturing, and in particular to a liquid crystal display with a novel structure. Background Technology

[0002] Small-sized LCD screens (such as 18.5-inch, 21.5-inch, and 23.6-inch) have advantages such as compact size, space saving, low power consumption, and affordable price. They are suitable for use as entertainment devices in small spaces such as bedrooms and kitchens, as computer monitors, or in scenarios such as in-vehicle displays and small commercial displays, meeting the audio-visual and display needs of compact environments.

[0003] In practical applications, small-sized LCD screens can serve as interactive terminals for various electronic devices (such as home smart home central control screens, vehicle smart control screens, etc.). Users can install them on the mounting surface and control the working status of electronic devices through the LCD screen, making them highly practical.

[0004] Therefore, users can only use it as a terminal for watching movies or controlling electronic devices. As the level of intelligence increases, users' functional requirements also increase. Conventional LCD screens are difficult to meet users' needs and there is room for improvement. Utility Model Content

[0005] In order to improve the functionality of the liquid crystal display screen, this application provides a liquid crystal display screen with a new structure.

[0006] The novel liquid crystal display screen provided in this application adopts the following technical solution:

[0007] A novel liquid crystal display screen includes a housing with a mounting portion for fixing the housing to a mounting surface. The housing has a mounting area, within which a first driving assembly and a projection lamp are disposed. The first driving assembly drives the projection lamp to rotate along the housing. A second driving assembly and a placement frame are also disposed on the mounting area located on one side of the first driving assembly. The second driving assembly drives the placement frame to slide along the mounting area.

[0008] By adopting the above technical solution, users can project partial information (such as time, temperature, etc.) through the projector lamp, increasing the functionality of the LCD screen. The projection angle of the projector lamp can be controlled by the first driving component according to the usage needs, so as to achieve the purpose of selecting the projection surface. At the same time, a placement rack is slidably set on the housing, through which users can place items such as microphones, giving the housing a certain storage capacity, which plays a positive guiding role in improving the functionality of the LCD screen.

[0009] Preferably, the first drive assembly includes a first DC motor and a reduction gear set, the output shaft of the first DC motor is connected to the input end of the reduction gear set, and the output end of the reduction gear set is connected to the projection lamp.

[0010] By adopting the above technical solution, through the cooperation of the first DC motor and the reduction gear set, the torque of the output shaft of the first DC motor is amplified by the reduction gear set and the speed is reduced, so that the projection lamp can rotate slowly and the rotation angle is controllable and highly stable.

[0011] Preferably, the installation area is provided with a slide rail along its length, and the placement frame is provided with a slider, the slide rail and the slider slidingly engaging.

[0012] By adopting the above technical solution, the placement rack can slide stably and smoothly along the shell through the cooperation of the slide rail and the slider, and the stability is high.

[0013] Preferably, a storage area is provided on the housing near the installation area. When the second drive component is in the initial state, the placement rack is located in the storage area. When the second drive component is in the extreme state, the placement rack slides along the storage area to the outer wall of the housing, and the placement rack is completely exposed outside the housing.

[0014] By adopting the above technical solution, the "hidden-unfold" design of the storage area and the shell allows the shelf to be located in the storage area when not in use, keeping the exterior of the LCD screen relatively tidy. At the same time, when the user uses the shelf, the shelf is completely exposed outside the shell, so it will not interfere with the user's access to the items placed in the shelf.

[0015] Preferably, a mounting groove is provided at the midpoint of the bottom of the housing along the length direction, and a rotating shaft is rotatably supported in the mounting groove. The rotating shaft is fixedly connected to the projection lamp and coaxially fixed to the output end of the reduction gear set. When the projection lamp is in the initial state, the light emitted by the projection lamp is parallel to the plane of the housing.

[0016] By adopting the above technical solution, the projection lamp is installed in the mounting slot through the rotating shaft, thereby storing the projection lamp through the mounting slot, making the surface of the housing relatively flat, which plays a positive guiding role in maintaining the aesthetic appearance of the housing.

[0017] Preferably, a reinforcing plate is detachably provided on the mounting part, and mounting holes are provided at the corners along the circumferential direction of the reinforcing plate, through which bolts can be used to fix the housing to the mounting surface.

[0018] By adopting the above technical solution, the reinforcing plate helps to improve the stability of the shell when it is installed on the mounting surface, and reduces the probability of cracks caused by deformation of the shell due to direct connection with the mounting surface over time.

[0019] Preferably, a magnetic auxiliary mounting block is detachably mounted on the surface of the housing opposite to the surface where the reinforcing plate is located. The magnetic auxiliary mounting block is used to fix itself to the mounting surface and magnetically engages with the reinforcing plate. A limiting groove is provided on the housing. The tolerance relationship between the outline dimensions of the limiting groove and the outline dimensions of the magnetic auxiliary mounting block is a transition fit. The thickness of the limiting groove is the same as the thickness of the magnetic auxiliary mounting block.

[0020] By adopting the above technical solution, when installing an LCD screen, the user can first install the magnetic auxiliary mounting block on the mounting surface. After positioning the magnetic auxiliary mounting block and the mounting surface, the housing can be quickly connected to the magnetic auxiliary mounting block through the cooperation of the limiting groove and the magnetic auxiliary mounting block. This reduces the probability of the housing being scratched or bumped during the installation process when the housing is directly installed on the mounting surface.

[0021] Preferably, the magnetic auxiliary mounting block is equipped with a level.

[0022] By adopting the above technical solution, since the magnetic auxiliary mounting block is equipped with a level, when installing the magnetic auxiliary mounting block and the mounting surface, the user can directly observe the angular deviation of the magnetic auxiliary mounting block through the level, without the need to use additional tools to calibrate the level of the magnetic auxiliary mounting block.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The projection lamp allows users to project partial information, increasing the functionality of the LCD screen. The projection angle of the projection lamp can be controlled by the first drive component according to usage needs, so as to select the projection surface. At the same time, a shelf is slidably installed on the housing, through which users can place items such as microphones, giving the housing a certain storage capacity, which plays a positive role in improving the functionality of the LCD screen.

[0025] 2. The projector lamp is installed in the mounting slot via a hinge, thereby storing the projector lamp through the mounting slot and making the surface of the housing relatively flat, which plays a positive guiding role in maintaining the aesthetic appearance of the housing;

[0026] 3. The reinforcing plate helps improve the stability of the housing when it is installed on the mounting surface, and reduces the probability of cracks caused by deformation of the housing due to direct connection with the mounting surface over time. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a novel liquid crystal display screen. (Refer to...) Figures 1-3 A novel liquid crystal display screen includes a housing 1, on which a mounting portion 2 is provided for fixing the housing 1 to a mounting surface. A mounting area 3 is formed by recessing the housing 1 along its thickness direction. In this embodiment, the housing 1 is integrally formed by injection molding. A first driving assembly 4 and a projection lamp 5 are disposed within the mounting area 3. The first driving assembly 4 drives the projection lamp 5 to rotate along the housing 1. A second driving assembly 6 and a placement frame 16 are also disposed on the mounting area 3 located on one side of the first driving assembly 4. The second driving assembly 6 drives the placement frame 16 to slide along the mounting area 3.

[0033] First, it should be noted that electronic components such as screens and main control circuit boards can be installed on the housing 1 to achieve the purpose of supporting electronic components such as screens and main control circuit boards.

[0034] Specifically, the first drive assembly 4 includes a first DC motor 41 and a reduction gear set 42. The output shaft of the first DC motor 41 is connected to the input end of the reduction gear set 42, and the output end of the reduction gear set 42 is connected to the projection lamp 5. The first DC motor 41 is installed within the mounting area 3, and the reduction gear set 42 is installed on one side of the first DC motor 41. The output shaft of the first DC motor 41 and the input end of the reduction gear set 42 are coaxially fixed, and the output end of the reduction gear set 42 is connected to the projection lamp 5. The reduction gear set 42 is a mechanical device that reduces speed and amplifies torque through the meshing of gears with different numbers of teeth. Its main components include a driving gear (small number of teeth for high-speed input) and several driven gears (large number of teeth for low-speed output). The difference in the number of teeth between the two achieves speed reduction and torque increase. Its specific composition and working principle will not be elaborated here.

[0035] Furthermore, a mounting groove 21 is provided at the midpoint of the bottom of the housing 1 along the length direction. A rotating shaft 11 is rotatably supported in the mounting groove 21. The rotating shaft 11 is fixedly connected to the projection lamp 5. The rotating shaft 11 is coaxially fixed to the output end of the reduction gear set 42. When the projection lamp 5 is in the initial state, the light emitted by the projection lamp 5 is parallel to the plane of the housing 1.

[0036] In this embodiment, the first DC motor 41 is electrically connected to the main control circuit board. The user can control the start and stop of the first DC motor 41 through a mobile terminal or remote control. Thus, when the user needs to adjust the angle of the projection lamp 5 along the housing 1, this can be achieved by controlling the rotation of the output shaft of the first DC motor 41. When the output shaft of the first DC motor 41 rotates, it will drive the reduction gear set 42, which is coaxially fixed with the output shaft of the first DC motor 41, to rotate, thereby achieving the purpose of adjusting the angle of the projection lamp 5 along the housing 1.

[0037] Among them, the projection lamp 5 can be used for general lighting or to display time, temperature, and text information. Users can customize it through mobile terminals or screens to enhance the user experience. It is an existing component, and its specific composition and working principle will not be described in detail here.

[0038] Furthermore, the installation area 3 is provided with a slide rail 7 along its length, and the placement frame 16 is provided with a slider 8. The slide rail 7 and the slider 8 slide together. The side wall of the placement frame 16 is integrally formed with a connecting block 15, and the slider 8 is installed on the connecting block 15. Thus, the connecting block 15 supports the placement component to slide along the slide rail 7, thereby improving the load-bearing capacity of the placement frame 16 and its stability when sliding along the slide rail 7.

[0039] The second drive assembly 6 includes a second DC motor 61 and a drive screw 62. The second DC motor 61 is located on one side of the first DC motor 41 and is symmetrically arranged with the first DC motor 41.

[0040] Correspondingly, the connecting block 15 has a threaded hole that is threadedly engaged with the drive screw 62. One end of the drive screw 62 is coaxially fixed with the output shaft of the second DC motor 61, and the other end is threadedly engaged with the connecting block 15. Thus, when the output shaft of the second DC motor 61 rotates, the drive screw 62 is coaxially fixed with the second DC motor 61, causing the drive screw 62 and the output shaft of the second DC motor 61 to rotate synchronously. Furthermore, because the drive screw 62 is threadedly engaged with the connecting block 15, the connecting block 15 is driven to slide along the mounting area 3.

[0041] It should also be noted that the second DC motor 61 is electrically connected to the main control circuit board. Users can also control the working status of the second DC motor 61 through a mobile terminal or remote control, thereby achieving the purpose of controlling the placement rack 16 to slide along the installation area 3.

[0042] The specific shape of the shelf 16 can be changed according to user or design requirements, such as cylindrical, cuboid, or irregular geometric shapes; it is not limited here. The shelf 16 can be used to place microphones or hang items (such as bouquets or decorations), and users can customize it according to their needs.

[0043] At the same time, refer to Figure 1 and Figure 2 A storage area 9 is provided on the housing 1 near the installation area 3. When the second drive assembly 6 is in the initial state, the placement rack 16 is located in the storage area 9. When the second drive assembly 6 is in the extreme state, the placement rack 16 slides along the storage area 9 to the outer wall of the housing 1, and the placement rack 16 is completely exposed to the outside of the housing 1.

[0044] Specifically, the storage area 9 is formed by a recess in the shell 1 along the thickness direction, and the thickness of the storage area 9 is greater than the thickness of the placement rack 16, so as to reduce the probability of mechanical interference when the placement rack 16 slides along the shell 1.

[0045] Furthermore, the initial and extreme states of the second drive component 6 are explained.

[0046] The initial state is when the second DC motor 61 is not in operation and the placement rack 16 is located in the storage area 9.

[0047] Correspondingly, when the output shaft of the second DC motor 61 moves, it drives the drive screw 62 to move synchronously with the output shaft of the second DC motor 61, thereby causing the connecting block 15 to carry the placement rack 16 to move out of the housing 1 until the placement rack 16 is completely exposed outside the housing 1, which is the limit state. At this time, the output shaft of the second DC motor 61 will stop working. When the output shaft of the second DC motor 61 moves in the opposite direction of the above rotation, it will cooperate with the drive screw 62 to drive the connecting block 15 to carry the placement rack 16 to move towards the storage area 9.

[0048] Therefore, the "hidden-unfold" design of the storage area 9 and the housing 1 allows the shelf 16 to be located inside the storage area 9 when not in use, keeping the exterior of the LCD screen relatively tidy. At the same time, when the user uses the shelf 16, the shelf 16 is completely exposed outside the housing 1, so it will not interfere with the user's access to the items placed inside the shelf 16.

[0049] Reference Figure 1 and Figure 3 A reinforcing plate 12 is detachably provided on the mounting part 2. The reinforcing plate 12 has mounting holes 121 at the corners along the circumference. The housing 1 can be fixed to the mounting surface by bolts through the mounting holes 121.

[0050] The reinforcing plate 12 can be made of metal to improve its rigidity. Meanwhile, the mounting part 2 is provided with a mounting groove 21. The tolerance fit of the mounting groove 21 and the tolerance fit of the reinforcing plate 12 is a transition fit, thereby limiting the placement position of the reinforcing plate 12 along the housing 1.

[0051] Correspondingly, during the production process of the housing 1, through holes are also provided on the mounting part 2, which correspond to the number and position of the mounting holes 121 on the reinforcing plate 12. When the reinforcing plate 12 is located in the mounting groove 21, the mounting holes 121 correspond one-to-one with the through holes.

[0052] The purpose is to improve the stability of the housing 1 when it is installed on the mounting surface by means of the reinforcing plate 12, and to reduce the probability of cracks caused by deformation of the housing 1 due to its direct connection with the mounting surface over time. At the same time, when the housing 1 is used to install on the mounting surface of a vehicle or other place where there is vibration, the reinforcing plate 12 helps to improve the stability of the housing 1 when it is installed on the mounting surface, and reduces the possibility of abnormal noise caused by excessive gap between the housing 1 and the mounting surface when subjected to vibration.

[0053] In another embodiment, reference is made to Figure 3A magnetic auxiliary mounting block 13 is detachably mounted on the surface of the housing 1 opposite to the surface where the reinforcing plate 12 is located. The magnetic auxiliary mounting block 13 is used to fix the housing to the mounting surface and magnetically engages with the reinforcing plate 12. A limiting groove 14 is provided on the housing 1. The outline dimensions of the limiting groove 14 and the outline dimensions of the magnetic auxiliary mounting block 13 are in a transition fit. The thickness of the limiting groove 14 is the same as the thickness of the magnetic auxiliary mounting block 13. Therefore, when installing the LCD screen, the user can first install the magnetic auxiliary mounting block 13 on the mounting surface. After positioning the magnetic auxiliary mounting block 13 with the mounting surface, the housing 1 can be quickly connected to the magnetic auxiliary mounting block 13 through the engagement of the limiting groove 14 and the magnetic auxiliary mounting block 13. This reduces the probability of the housing 1 being scratched or bumped during the installation process when the housing 1 is directly installed on the mounting surface.

[0054] Correspondingly, the magnetic auxiliary mounting block 13 is equipped with a level 131, which can be a bubble level 131. The magnetic auxiliary mounting block 13 has a slot 10 on its side wall along its length. During assembly, the level 131 can be directly inserted into the slot 10, simplifying installation and positively contributing to reduced production costs. Because the magnetic auxiliary mounting block 13 has a level 131, users can directly observe the angular deviation of the magnetic auxiliary mounting block 13 when installing it onto the mounting surface, without needing to use additional tools to calibrate its level.

[0055] The implementation principle of a novel liquid crystal display screen according to an embodiment of this application is as follows: the user can project some information (such as time, temperature, etc.) through the projection lamp 5, which increases the functionality of the liquid crystal display screen. The projection angle of the projection lamp 5 can be controlled by the first driving component 4 according to the usage requirements, so as to achieve the purpose of selecting the projection surface. At the same time, a placement rack 16 is slidably provided on the housing 1. The user can place items such as microphones through the placement rack 16, so that the housing 1 has a certain storage capacity, which plays a positive guiding role in improving the functionality of the liquid crystal display screen.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
