[0043] As users pursue thinner devices, the thickness of wall-mounted display devices is getting thinner and thinner, so thin that the display device is basically attached to an external device, such as a wall. However, when the display device is basically attached to an external device, its heat dissipation performance is greatly reduced, which may cause the components inside to be damaged by high temperature or reduce the service life of the components. Therefore, in order to overcome this technical problem, the embodiment of the present application proposes a display device.

[0044] Specifically, refer to Figure 1 , Figure 2and Figure 3 As shown, the embodiment of the present application provides a display device 100, including:

[0045] The housing 110 has a clearance hole H1;

[0046] A movable connection mechanism 120, which is disposed on the housing 110; the movable connection mechanism 120 is used to connect to an external device 200; and

[0047] The push rod 130 is configured to be inserted into the clearance hole H1 and can move relative to the shell 110; and the push rod 130 has a first position. When the push rod 130 is in the first position, it extends to the outside of the shell 110 through the clearance hole H1 and applies a thrust to the external device 200; the movable connection mechanism 120 is configured to drive the shell 110 away from the external device 200 to the east based on the thrust.

[0048] In the technical solution of the embodiment of the present application, a movable connection mechanism 120 is provided on the shell 110, and the movable connection mechanism 120 is connected to the external device 200, so that the display device 100 is installed on the external device 200; the display device 100 also includes a push rod 130, which is configured to be inserted into the clearance hole H1 and movable relative to the shell 110, and has a first position; when the push rod 130 is in the first position, it extends to the outside of the shell 110 through the clearance hole H1 and begins to apply a thrust to the external device 200; the movable connection mechanism 120 is configured to drive the shell 110 away from the external device 200 based on the thrust, thereby increasing the spacing of the interval space S1 between the shell 110 and the external device 200, so that the high-temperature airflow in the display device 100 can easily flow to the external environment, so that the heat dissipation capacity of the display device 100 is enhanced, so as to avoid the problem of damage to internal components of the display device 100 or reduction in the service life of the components due to high temperature.

[0049] It should be noted that in the technical solution of the embodiment of the present application, the external device 200 is a structure for installing the display device 100, such as a wall, etc. In the technical solution of the embodiment of the present application, the display device 100 is a wall-mounted display device 100, such as a wall-mounted TV, especially an ultra-thin wall-mounted TV.

[0050] It should be noted that the housing 110 of the display device 100 is provided with heat dissipation holes for heat dissipation, and the heat dissipation holes are spaced apart from the clearance hole H1.

[0051] It is easy to understand that in the technical solution of the embodiment of the present application, the push rod 130 passes through the clearance hole H1 and can move relative to the housing 110. The push rod 130 can extend out of the housing through the clearance hole H1, and can also retract into the housing through the clearance hole H1. Figure 3 As shown in the figure, the push rod 130 is retracted into the shell through the clearance hole H1 and has a second position; when the push rod 130 is in the second position, the push rod 130 is out of contact with the external device 200; the movable connection mechanism 120 is also configured to drive the display device 100 to move toward the external device 200 when there is no thrust from the push rod 130, so as to reduce the gap between the display device 100 and the external device 200, so as to achieve the purpose of ultra-thin installation.

[0052] As an optional implementation of the above embodiment, Figure 3 As shown, the display device 100 includes a fixing member 150, which is disposed on the housing 110. The display device also includes a heated bending member 140, which is disposed on the fixing member 150. The heated bending member 140 is configured to bend when heated. The push rod 130 is disposed on the heated bending member 140. When the temperature inside the display device 100 rises, the heated bending member 140 bends, thereby driving the push rod 130 to move toward the external device 200. When the push rod 130 moves to the first position, a thrust is applied to the external device 200 based on the bending deformation of the heated bending member 140.

[0053] As an optional implementation of the above embodiment, the heated bending member 140 is a bimetallic strip. A bimetallic strip is a composite material composed of two or more metals or other materials with suitable properties. A bimetallic strip is also called a thermal bimetallic strip. Since the thermal expansion coefficients of each component layer are different, when the temperature changes, the deformation of the active layer is greater than the deformation of the passive layer, so that the entire bimetallic strip will bend toward the passive layer, and the curvature of the composite material will change to produce deformation. When the bimetallic strip bends, the push rod 130 is pushed to move from the second position to the first position to act on the external device 200, and then a thrust is applied to the external device 200 by means of the bending deformation, thereby forcing the movable connection mechanism 120 to drive the display device 100 away from the external device 200.

[0054] As an optional implementation of the above embodiment, the fixing member 150 is connected to the housing 110, and the fixing member 150 is connected to the heated bending member 140. A bending space S2 is defined between the fixing member 150 and the housing 110.

[0055] For example, in some embodiments, Figure 3As shown, both ends of the fixing member 150 are fixed to the structure inside the housing, and are spaced apart from the outer shell of the housing 110 to define a bending space S2. Both ends of the heated bending member 140 are fixed to the fixing member 150 by screws and are located in the bending space S2. After the heated bending member 140 is mounted on the fixing member 150, the bending space S2 defined by the main body and the housing 110 provides space for the heated bending member 140 to bend, so that the heated bending member 140 can bend when the temperature rises.

[0056] For another example, the fixing member 150 is constructed as a seat body. The fixing seat is usually formed integrally on the housing 110. The fixing seat is formed with a fixing groove. The heated bending member 140, such as a bimetallic strip, is arranged in the fixing groove. Both ends of the bimetallic strip are fixed to the side wall of the fixing groove by screws. The fixing groove is connected to the bending space S2.

[0057] As an optional implementation of the above embodiment, Figure 3 As shown, the fixing member 150 is arranged on the inner side of the shell 110. The shell 110 has a clearance hole H1, and the clearance hole H1 is connected to the bending space S2. When the heated bending member 140 is bent by heat, the push rod 130 extends to the outer side of the shell 110 through the clearance hole H1. One end of the push rod 130 is fixed to the heated bending member 140, and the other end extends out of the fixing member 150 through the clearance hole H1. In an embodiment, one end of the push rod 130 is fixed to the heated bending member 140, and the other end extends out of the fixing member 150 through the clearance hole H1. When the heated bending member 140 is bent, the push rod 130 is prompted to move relative to the fixing member 150 based on its bending deformation.

[0058] As an optional implementation of the above embodiment, Figure 4 As shown, both ends of the heated bending member 140 are fixed to the fixing member 150. Generally speaking, the upper and lower ends of the bimetallic strip are riveted together and fixed to the fixing member 150, such as by screws. In some embodiments, the heated bending member 140 may also be a memory alloy. The memory alloy is fixed to the fixing member 150, such as by screws.

[0059] In an embodiment, the push rod 130 may be fixed to the heated bending member 140 by means of a screw, or may be welded to the heated bending member.

[0060] In the embodiment, one end of the push rod 130 is fixed at the middle position of the heated curved member 140. The middle position of the heated curved member 140 is the position where its deformation is the largest, so that the push rod 130 has a sufficient movement stroke and generates a large thrust.

[0061] In the technical solution of the embodiment of the present application, in order to keep the appearance of the display device 100 neat and tidy, the push rod 130 is usually built into the housing 110. To this end, in some embodiments of the present application, the housing 110 has a clearance hole H1 to facilitate the push rod 130 to extend from the inside to the outside.

[0062] As an optional implementation of the above embodiment, Figure 1 As shown, the movable connection mechanism 120 includes:

[0063] A first rotating shaft seat, the first rotating shaft seat is disposed on the housing 110;

[0064] A first rotating shaft 121, wherein the first rotating shaft 121 is rotatably connected to the first rotating shaft seat;

[0065] A second rotating shaft seat, the second rotating shaft seat is used to connect the external device 200;

[0066] A second rotating shaft 122, the second rotating shaft 122 is rotatably connected to the second rotating shaft seat; the second rotating shaft 122 is arranged parallel to the first rotating shaft 121; and

[0067] The connecting rod 123 has two opposite ends connected to the first rotating shaft 121 and the second rotating shaft 122 respectively.

[0068] In this embodiment, when the push rod 130 acts on the external device 200, the display device 100 is subjected to a reaction force from the external device 200, and the first rotating shaft 121 rotates relative to the first rotating shaft seat, and the first rotating shaft 121 also moves away from the external device 200, thereby driving the second rotating shaft 122 at the other end thereof to move relative to the second rotating shaft seat, and then the display device 100 moves relative to the external device 200 while the movable connection mechanism 120 keeps the display device 100 installed.

[0069] As an optional implementation of the above embodiment, Figure 1 , Figure 5 As shown, the push rod 130 is disposed on the lower side of the movable connection mechanism 120 in the direction of gravity, and the movable connection mechanism 120 is disposed on the upper side of the center of gravity of the display device 100. When the push rod 130 cancels the thrust on the external device 200, the display device 100 will automatically reset to be close to the external device 200 by virtue of the gravity of the display device 100.

[0070] As an alternative implementation of the above embodiment, the push rod 130 has at least one. Figure 1As shown, the number of push rods 130 can be one, which is usually used for a relatively small display device 100. In other embodiments, the number of push rods 130 can be two or more, which is usually used for a relatively large display device 100, such as Figure 5 Two shown.

[0071] In some other technical solutions of the embodiments, Figure 6 As shown, the movable connection mechanism 120 may include a first fixed cylinder 124, a second fixed cylinder 126 and a spring 125. The first fixed cylinder 124 is fixedly mounted on the housing 110, and the second fixed cylinder 126 is fixedly mounted on the external device 200. The first fixed cylinder 124 is sleeved on the second fixed cylinder, and the spring 125 is arranged in the cylinder body of the first fixed cylinder 124 and the second fixed cylinder 126, connecting the housing 110 and the external device 200. When the push rod 130 generates thrust, the first fixed cylinder 124 moves away from the external device 200 relative to the second fixed cylinder, the spring is deformed, and the display device 100 moves away from the external device 200. When the push rod 130 cancels the thrust, the spring recovers the deformation, the first fixed cylinder 124 moves closer to the external device 200 relative to the second fixed cylinder, and the display device 100 approaches the external device 200.

[0072] As an optional implementation of the above embodiment, Figure 7 As shown, the display device 100 further includes a motor 160, which is disposed on the housing 110 and is configured to drive the push rod 130 to move toward the first position. The motor 160 is used to drive the push rod 130 to move toward the first position, so that the push rod 130 acts on the external device 200, thereby causing the display device 100 to move away from the external device 200. In an embodiment, a base for mounting the motor 160 may be formed on the housing 110. The motor 160 is fixed to the base by a screw.

[0073] In an embodiment, the motor 160 may be mounted on a rib plate inside the housing 110 .

[0074] In an embodiment, a user may input an instruction to the display device 100 , and the motor 160 may control the push rod 130 to be pushed out in response to the instruction, so as to increase the distance between the display device 100 and the external device 200 .

[0075] In some other embodiments, the display device 100 may include a controller (not shown) and a temperature sensor (not shown). The temperature sensor and the controller are both installed in the display device 100. The temperature sensor is electrically connected to the controller, and the controller receives the temperature signal of the temperature sensor. The controller is electrically connected to the motor 160, and is used to output control instructions to the motor 160. The controller can be a circuit board inside the display device 100, on which a temperature control chip is installed. The temperature sensor is electrically connected to the temperature control chip. When the temperature value corresponding to the temperature signal of the temperature sensor received by the controller exceeds a preset value, the controller outputs a control instruction to the motor 160, and the motor 160 drives the push rod 130 to move toward the first position to cause the display device 100 to move away from the external device 200.

[0076] In an embodiment, when heat dissipation is not required, the motor 160 drives the push rod 130 to move away from the external device 200 , and the display device 100 is reset to maintain a minimum distance from the external device 200 .

[0077] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the application concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
