[0048] In order to illustrate the technical solutions described in the present application, the following will be described in detail with reference to specific accompanying drawings and embodiments.

[0049] Please refer to Figures 1 to 3As shown in the figure, an embodiment of the present application provides a ceiling-mounted display device 100, which includes a main chassis 4, a display panel 5, and a mounting plate 6. The main chassis 4 includes a chassis body 42 and a main unit 41 disposed inside the chassis body 42. The main unit 41 is connected to the display panel 5, including physical connection and electrical connection. The main unit 41 provides power and a display signal for the display panel 5. Thus, the display panel 5 can be used to display a picture. The mounting plate 6 is used to be fixed to a mounting position, such as the lower surface of a ceiling or a cabinet bottom plate, etc.

[0050] In this embodiment, the ceiling-mounted display device 100 further includes a slide rail part 3. The slide rail part 3 includes a connecting part 31 and a limiting part 32 which are bent and connected, as Figure 5 shown.

[0051] Among them, referring to Figure 5 、 Figure 6 and Figure 9 shown, one side of the connecting part 31 facing away from the limiting part 32 is bent and connected to the mounting plate 6. A chute 420 is provided on the chassis body 42 and opened from its rear end surface. The chute 420 is configured to allow the connecting part 31 to be inserted, so that the limiting part 32 is restricted to the side of the chassis body 42 facing away from the mounting plate 6.

[0052] During actual installation, first fix the mounting plate 6 to the mounting position, and then align the chute 420 of the chassis body 42 with the connecting part 31, and slide the main chassis 4 from front to back, and the connecting part 31 enters the chute 420.

[0053] Alternatively, it can be replaced that one side of the connecting part 31 facing away from the limiting part 32 is bent and connected to the chassis body 42. A chute 420 is provided on the mounting plate 6 and opened from its front end surface. The chute 420 is configured to allow the connecting part 31 to be inserted, so that the limiting part 32 is located on the side of the mounting plate 6 facing away from the chassis body 42.

[0054] Similarly, during actual installation, first fix the mounting plate 6 to the mounting position, and then align the connecting part 31 with the chute 420 on the mounting plate 6, and slide the main chassis 4 from front to back, and the connecting part 31 enters the chute 420.

[0055] Regardless of which method, when installing the ceiling-mounted display device 100 provided by the embodiment of the present application, the connection between the main chassis 4 and the mounting plate 6 is realized by the sliding fit and limitation between the slide rail part 3 and the chute 420. There is no need to lift the main chassis 4 as a whole and then drive screws, and the installation is more convenient, reducing the difficulty and time-consuming of manual operation.

[0056] It should be noted that the above-mentioned "front" and "rear" are determined based on the orientation of the user when using the ceiling-mounted display device 100. The side of the ceiling-mounted display device 100 facing the user is its front side, and the side facing away from the user is its rear side.

[0057] The slide rail part 3 and the mounting plate 6 can be integrally formed, or can be separately manufactured and connected. The slide rail part 3 and the box body 42 can be integrally formed, or can be separately manufactured and connected.

[0058] For the convenience of description, in the embodiments of the present application, the slide rail part 3 is described as a component connected to the mounting plate 6 or the box body 42. It can be understood that in some cases, the slide rail part 3 can actually be a part of the mounting plate 6 or the box body 42. The other part of the mounting plate 6 is the main body of the mounting plate 6, which is mainly used for fixing to the installation position; the other part of the box body 42 is the main body of the box body 42, which is mainly used for forming a space capable of accommodating the host 41.

[0059] Please refer to Figure 2 、 Figure 7 and Figure 8 As shown, in one embodiment, the top-mounted display device further includes a hinge assembly 9, which is connected between the display panel 5 and the box body 42 to allow the display panel 5 to have a first state of being opened relative to the main chassis 4, as shown in Figure 2 shown, and a second state that can be stored in the box body 42, as shown in Figure 1 shown.

[0060] When the user needs to view the picture of the display panel 5, the display panel 5 can be opened. After viewing, the display panel 5 is rotated and stored in the main chassis 4, which can reduce the space occupation.

[0061] Please refer to Figure 7 and Figure 8 As shown, the hinge assembly 9 includes a first connecting body 91, a second connecting body 92 and a rotating shaft 93. The first connecting body 91 is fixedly connected to the display panel 5 and is circumferentially fixedly connected to the rotating shaft 93. The second connecting body 92 is fixedly connected to the box body 42 and is rotatably connected to the rotating shaft 93.

[0062] The specific forms of the first connecting body 91, the second connecting body 92 and the rotating shaft 93 are not limited, as long as the first connecting body 91 and the second connecting body 92 can rotate relative to each other.

[0063] For example, Figure 8 As shown, in one embodiment, the rotating shaft 93 includes a shaft body 931 and an end shaft sleeve 932. One end of the shaft body 931 forms an external thread portion 9311 that is threadedly engaged with the end shaft sleeve 932. The other end of the shaft body 931 forms a shaft head 9310 with a larger size. At least part of the position on the shaft body 931 forms a flat position 9312. The first connecting body 91 is provided with a flat hole 910 adapted to the flat position 9312. The second connecting body 92 is provided with a round hole 920 adapted to the shaft body 931, and the first connecting body 91 and the second connecting body 92 are restricted between the shaft head 9310 and the shaft sleeve.

[0064] Among them, in order to keep a certain distance between the first connector 91 and the second connector 92 to avoid mutual influence between them, as Figure 8 shown, the rotating shaft 93 further includes at least one spacer bushing 934 sleeved on the shaft body 931 and located between the first connector 91 and the second connector 92. The spacer bushing 934 is provided with a round hole 920 or a flat hole 910 adapted to the shaft body 931. Or, as Figure 8 shown, a round hole 920 is provided on one spacer bushing 934, and a flat hole 910 is provided on the other spacer bushing 934. The spacer bushing 934 provided with the flat hole 910 can be arranged close to the first connector 91 or close to the second connector 92.

[0065] In addition, please refer to Figure 8 shown. In one embodiment, the rotating shaft 93 further includes a limiting bushing 935 axially cooperating with the second connector 92. The limiting bushing 935 is sleeved on the shaft body 931 and is provided with a flat hole 910 adapted to the flat position 9312 on the shaft body 931. Concave-convex cooperation (the cooperation of the concave part and the protruding part) is formed on the axially facing end surfaces of the limiting bushing 935 and the second connector 92. In this way, when the second connector 92 is rotated, the second connector 92 can be held at a certain angle by the restriction of the limiting bushing 935 on the second connector 92. The axial dimensions of the said concave part and protruding part are designed appropriately to allow the user to push the second connector 92 to rotate and break away from the restriction of the concave-convex cooperation in the circumferential direction when applying a certain force.

[0066] In other alternative embodiments, the first connector 91 can be fixedly connected to the display panel 5 and rotatably connected to the rotating shaft 93, and the second connector 92 is fixedly connected to the box body 42 and circumferentially fixedly connected to the rotating shaft 93.

The shielding plate 96 includes a first plate body 961, a second plate body 962 and a third plate body 963 which are sequentially bent and connected. The first plate body 961 is fixedly connected to the connecting portion 31 or the second connector 92, and the second plate body 962 and the third plate body 963 are respectively located on the sides of the rotating shaft 93. The shielding plate 96 is used to shield the rotating shaft 93 during the rotation of the display panel 5 to ensure that the rotating shaft 93 is not visible from the outside at any rotation angle of the display panel 5.

[0068] Please refer to Figure 3 and Figure 4As shown, in one embodiment, the ceiling-mounted display device 100 also includes a fixing component, the fixing component includes at least one fixing member 81, the fixing member 81 includes a head 811 and a screw 812, a fixing hole 60 is provided on the mounting plate 6, and the end of the screw 812 away from the head 811 is used to be fixed to the mounting position, that is, the screw 812 is driven into the mounting position, such as the inside of the bottom plate of a wall or a cabinet, through the external thread (not shown) on the screw 812, and the head 811 is used to abut against the side of the mounting plate 6 facing the box body 42, so that the mounting plate 6 is fixed in the mounting position.

[0069] In one embodiment, the fixing assembly includes a plurality of fixing members 81 , and correspondingly, a plurality of fixing holes 60 are provided on the mounting plate 6 to provide a multi-point fixing installation of the mounting plate 6 .

[0070] Please continue reading Figure 3 and Figure 4 As shown, in one embodiment, one or more fixing holes 60 are arc holes to allow the screw 812 to slide in the arc holes, that is, relative rotation between the mounting position and the mounting plate 6 is achieved, and further, the display panel 5 is rotated relative to the mounting position. Among them, one fixing hole 60 can be a circular hole as the center point of rotation of the main box 4.

[0071] In a specific embodiment, the fixing assembly includes three fixing members 81 , and the mounting plate 6 is provided with three fixing holes 60 , two of which are arc-shaped holes.

[0072] Please continue reading Figure 3 As shown, the mounting plate 6 is provided with a plurality of groups of fixing holes 60, and each group of fixing holes 60 is distributed in different positions and ranges, so as to ensure that the mounting plate 6 can be installed on mounting positions of different sizes. For example, in the first group of fixing holes 60, the plurality of fixing holes 60 are spaced farther apart, and in the second group of fixing holes 60, the plurality of fixing holes 60 are spaced closer together. When the size of the cabinet bottom plate is small, the second group of fixing holes 60 can be selected.

[0073] Each group of fixing holes 60 includes a plurality of fixing holes 60 , and in each group of fixing holes 60 , one or more fixing holes 60 are arc-shaped holes.

[0074] See also Figure 4 As shown, the fixing member 81 further includes a pin portion 813 connected between the head 811 and the screw rod 812, and the pin portion 813 is located in the fixing hole 60. The size of the pin portion 813 is designed to be slightly smaller than the width of the fixing hole 60, and is used to position the mounting plate 6.

[0075] Among them, the pin part 813 can be fixedly connected between the head part 811 and the screw rod 812, or can be rotatably arranged between the head part 811 and the screw rod 812. For example, the pin part 813 passes through the screw rod 812, and in the axial direction of the screw rod 812, the pin part 813 is located between the head part 811 and the external thread of the screw rod 812.

[0076] Please refer to Figure 1 and Figure 2 As shown, in one embodiment, the size of the mounting plate 6 in the front-back direction is larger than the size of the main chassis 4. In particular, the rear end of the mounting plate 6 extends beyond the rear end of the main chassis 4. The purpose of such a design is to prevent the rear end of the main machine 41 from directly touching a wall or the like during installation or use.

[0077] In one embodiment, the rear end face of the mounting plate 6 is designed as a curved surface, specifically, an arc surface. When the rear end of the mounting plate 6 is very close to the wall, the rotation of the mounting plate 6 is also allowed.

[0078] Next, please refer to Figure 9 As shown, it further includes a locking component 7, and the locking component 7 includes a reset member 71 and a stopping portion 72 that are connected to each other; among them, one end of the reset member 71 facing away from the stopping portion 72 is fixedly connected to the box body 42, and a limiting groove 310 for the stopping portion 72 to slide into is provided on the mounting plate 6. Referring to Figure 5 As shown; alternatively, one end of the reset member 71 facing away from the stopping portion 72 is fixedly connected to the mounting plate 6, and a limiting groove 310 for the stopping portion 72 to slide into is provided on the box body 42. And, the sliding direction of the stopping portion 72 is inclined to the direction of the sliding groove 420.

[0079] By compressing the reset member 71 in the sliding manner of the stopping portion 72, the stopping portion 72 is separated from the limiting groove 310. Furthermore, the main chassis 4 can be separated from the mounting plate 6, and after the main chassis 4 slides into place on the mounting plate 6, the stopping portion 72 is released, and the reset member 71 pushes the stopping portion 72 to slide and enter the limiting groove 310, which can limit the sliding of the main chassis 4 and prevent the main chassis 4 from falling off the mounting plate 6.

[0080] The reset member 71 can be a compression spring or other forms of elastic members that can be reset after being compressed.

[0081] In one embodiment, the sliding direction of the stopping portion 72 is perpendicular to the sliding direction of the sliding rail portion 3.

[0082] In one embodiment, in order to simplify the processing and manufacturing of the mounting plate 6, the reset member 71 and the stopping portion 72 are arranged on the box body 42, and the limiting groove 310 is formed on the mounting plate 6.

[0083] In one embodiment, such as Figure 9As shown, a stop end 720 is formed on the stop portion 72, and the stop end 720 enters and exits the limit groove 310 in a sliding manner.

[0084] As Figure 9 shown, both the reset member 71 and the stop portion 72 are located on the side of the box body 42 facing away from the mounting plate 6, that is, the inner side. One end of the reset member 71 facing away from the stop portion 72 is fixedly connected to the side surface of the box body 42 facing away from the mounting plate 6, that is, its inner surface; the limit groove 310 is provided on the connecting portion 31. When the connecting portion 31 enters the sliding groove 420, the limit groove 310 is located inside the box body 42. In this way, at least most of the structure of the locking assembly 7 can be made invisible.

[0085] Please continue to refer to Figure 9 and Figure 10 shown, in one embodiment, the locking assembly 7 further includes a first guiding portion 73 fixedly connected to the stop portion 72. A first guiding groove 44 is provided on the box body 42. Refer to Figure 6 shown, the first guiding portion 73 slides in the first guiding groove 44. Optionally, the sliding direction of the first guiding portion 73 is parallel to the sliding direction of the stop portion 72. Through the sliding fit of the first guiding portion 73 and the first guiding groove 44, the sliding direction of the stop portion 72 can be limited, avoiding the situation where the stop portion 72 slides and deviates and cannot enter or disengage from the limit groove 310.

[0086] In one embodiment, a part of the first guiding portion 73 is located outside the box body 42, and the other part is located inside the box body 42. The part located outside the box body 42 is for the user to operate and press to push the stop portion 72 to slide.
