Description

Control box for a display device and wireless display system including the same

[0001] The present invention relates to a control box for a display device and a wireless display system including the same.

[0002] With the recent advancement of wireless communication technology, the development of wireless communication devices utilizing Wireless LAN (WLAN) technology is actively underway.

[0003] A representative example is a wireless display system comprising a transmitting device (hereinafter referred to as a "control box") that adopts a wireless LAN to encode an AV signal received through a cable or antenna into an MPEG stream and transmits the encoded MPEG stream through a wireless channel, and a receiving device (hereinafter referred to as a "display device") that receives the MPEG stream transmitted from the control box, decodes it, and then displays it on a screen.

[0004] Accordingly, users can easily move the receiving device within the wireless communication range, allowing them to view videos in areas such as the kitchen, terrace, and garden. Additionally, aesthetics can be improved as the display device's wires are eliminated.

[0005] Meanwhile, setting the antenna position is a crucial factor for the control box to ensure smooth wireless communication with the display device. However, conventional control boxes present a problem of inconvenience in use because the antenna position must be manually adjusted and changed.

[0006] Embodiments of the present invention can provide a control box for a display device with improved usability and a wireless display system including the same by automatically controlling the rotation direction of an antenna through an actuator.

[0007] Embodiments of the present invention can provide a control box for a display device and a wireless display system including the same, which can dissipate heat generated from an antenna more quickly and efficiently by rotating the antenna while it is coupled to a heat dissipation member.

[0008] Embodiments of the present invention can provide a control box for a display device and a wireless display system including the same, which can prevent the heat dissipation member from tilting during rotation by providing an eccentricity prevention member for maintaining left-right balance during rotational driving of the heat dissipation member.

[0009] Embodiments of the present invention can provide a control box for a display device and a wireless display system including the same, in which the rotational speed of the antenna is improved because the actuator does not require a reduction gear such as a spur gear.

[0010] Embodiments of the present invention can provide a control box for a display device and a wireless display system including the same, which can improve the rotational speed of an antenna by stably supporting a heat dissipation member rotating at high speed and minimizing the rotational friction of the motor by including a bearing in which an actuator rotatably supports a heat dissipation member.

[0011] The problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0012] Embodiments of the present invention may provide a control box for a display device comprising: a case having an internal receiving space; a heat dissipation member rotatably disposed in the receiving space; an antenna fixed to the heat dissipation member; and an actuator coupled to the heat dissipation member and rotating the heat dissipation member equipped with the antenna.

[0015] According to embodiments of the present invention, a control box for a display device and a wireless display system including the same can be provided, wherein the antenna is rotated while coupled to a heat dissipation member, thereby dissipating heat generated from the antenna more quickly and efficiently.

[0016] According to embodiments of the present invention, a control box for a display device and a wireless display system including the same can be provided, which can prevent the heat dissipation member from tilting during rotation by providing an eccentricity prevention member for maintaining left-right balance during rotational driving of the heat dissipation member.

[0017] According to embodiments of the present invention, since the actuator does not require a reduction gear such as a spur gear, a control box for a display device with improved antenna rotation speed and a wireless display system including the same can be provided.

[0018] According to embodiments of the present invention, a control box for a display device and a wireless display system including the same can be provided, wherein the actuator includes a bearing that rotatably supports a heat dissipation member, thereby stably supporting a heat dissipation member rotating at high speed while minimizing rotational friction of the motor to improve the rotational speed of the antenna.

[0030] Hereinafter, some embodiments of the present invention will be described in detail with reference to the exemplary drawings. In assigning reference numerals to the components of each drawing, the same components may have the same reference numeral as much as possible, even if they are shown in different drawings.

[0034] Meanwhile, where numerical values ​​or corresponding information regarding a component (e.g., levels, etc.) are mentioned, even without separate explicit notation, the numerical values ​​or corresponding information may be interpreted as including a range of error that may occur due to various factors (e.g., process factors, internal or external shocks, noise, etc.).

[0035] Hereinafter, various embodiments of the present invention will be described in detail with reference to the attached drawings.

[0036] FIG. 1 is a perspective view of a wireless display system according to one embodiment of the present invention, FIG. 2 is a perspective view of a control box for a display device according to one embodiment of the present invention, and FIG. 3 is an internal configuration diagram of a control box for a display device according to one embodiment of the present invention.

[0037] Referring to FIGS. 1 to 3, the wireless display system (1) may include a display device (100) that outputs an image and a control box (200) that is paired with the display device (100) and transmits image data to the display device (100).

[0038] The display device (100) may include a display panel (110) for displaying an image. For example, the display panel (110) may include a light-emitting element for displaying an image, and a circuit, wiring, and components for driving the light-emitting element.

[0039] The display device (100) may include one selected from a Liquid Crystal Display device (LCD), a Plasma Display Panel device (PDP), a Field Emission Display device (FED), and an Organic Light Emitting Display device (OLED).

[0040] The control box (200) may include a case (210), a heat dissipation member (220), an antenna (230), an actuator (240), and a heat dissipation fan (250).

[0041] The case (210) may be formed in a box shape having an internal receiving space (210a). For example, the case (210) may include a main body (211) and a cover (212).

[0042] The main body (211) is provided with a receiving space (210a) inside, and an opening (210b) communicating with the receiving space (210a) may be formed at the top. Accordingly, various parts can be stored inside the main body (211) through the opening (210b).

[0043] The cover (212) can shield the opening (210b) of the main body (211). For example, a through hole (212a) may be formed on one side of the cover (212), and a dial (213) for pivoting the antenna (230) may be exposed to the outside through the through hole (212a).

[0044] A support plate (214) to which an actuator (240) is coupled may be provided in the receiving space (210a) of the case (210), and a plurality of heat exchange holes (211a) for circulating air inside the case (210) with air outside the case (210) may be formed on at least one side.

[0045] The heat dissipation member (220) is intended to cool heat generated from the antenna (230) and can be rotatably positioned in the receiving space (210a) of the case (210). For example, the heat dissipation member (220) can be rotated within the case (210) by means of an actuator (240) described later, and can be formed of a metal material such as copper, aluminum, or nickel that has good thermal conductivity.

[0046] The antenna (230) can be fixed to one side of the heat dissipation member (220). For example, the antenna (230) can be fixed to one side of the heat dissipation member (220) using fastening means such as adhesive, double-sided tape, or bolts. Accordingly, the antenna (230) can rotate in conjunction with the heat dissipation member (220).

[0047] The antenna (230) can transmit and receive wireless signals to and from an external display device (100). For example, the antenna (230) can transmit an AV signal, including audio and video signals, to the external display device (100). Accordingly, the display device (100) can receive the AV signal and output an image to the outside through the display panel (110).

[0048] The actuator (240) is coupled to the lower part of the heat dissipation member (220) and can rotate the heat dissipation member (220) equipped with an antenna (230). For example, the actuator (240) can be fixed on a support plate (214) through fastening means such as a bolt, and the heat dissipation member (220) equipped with an antenna (230) can be coupled to the rotation axis of the actuator (240). Accordingly, the heat dissipation member (220) and the antenna (230) can rotate clockwise or counterclockwise by the driving of the actuator (240). In this way, as the antenna (230) rotates by the actuator (240), the direction of transmission of the wireless signal can be changed.

[0049] The position of the actuator (240) can be controlled to face the intensity of the signal generated from the display device (100). To this end, the control box (200) may further include a signal intensity measuring unit that measures the signal intensity of the display device (100) and a control unit (260) that rotates the rotary actuator (240) so that it faces the direction in which the signal measured through the signal intensity measuring unit is greatest. For example, the signal intensity measuring unit may be included in the control unit (260).

[0050] In this way, as the rotary actuator (240) rotates so that it faces the direction in which the signal strength generated from the display device (100) is greatest, the direction of the antenna (230) connected to the rotary actuator (240) can be automatically controlled, thereby making the use of the control box (200) more convenient.

[0051] A heat dissipation fan (250) is intended to draw in air heated by heat generated from the antenna (230) and discharge it outside the case (210), and can be placed in the receiving space (210a). As such, with the heat dissipation fan (250) provided within the receiving space (210a), the air heated by heat generated from the antenna (230) can undergo a second heat exchange by the heat dissipation fan after being heat-exchanged first by the heat dissipation member (220).

[0052] Therefore, by preventing the temperature inside the control box (200) from rising rapidly, it is possible to prevent performance degradation during operation of the control box (200).

[0053] FIG. 4 is a perspective view of a heat dissipation member and an actuator according to one embodiment of the present invention, FIG. 5 is a side view of FIG. 4, and FIG. 6 is an exploded perspective view of FIG. 4.

[0054] Referring to FIGS. 4 to 6, the heat dissipation member (220) may include a connecting plate (221), a first extension part (222), a second extension part (223), and a heat exchange part (224).

[0055] The connecting plate (221) can be coupled to the upper part of the actuator (240). For example, the connecting plate (221) may have a storage space (221a) formed on one side of its lower surface so that a portion of the upper part of the actuator (240) can be accommodated inside. The connecting plate (221) can be coupled to the actuator (240) through a fastening member such as a bolt.

[0056] The first extension (222) may extend in one direction from one end of the connecting plate (221). For example, the first extension (222) may be formed in the shape of a square plate, and a first reinforcing plate (225) may be placed between the connecting plate (221) and the first extension (222) to prevent deformation due to the weight of the heat exchanger (224).

[0057] The second extension (223) may be extended in a different direction from the other end of the connecting plate (221). The second extension (223) may be formed in a square plate shape, similar to the first extension (222), and a second reinforcing plate (226) may be placed between the connecting plate (221) and the second extension (223) to prevent deformation caused by the weight of the eccentricity prevention member (270).

[0058] The heat exchanger (224) may be disposed at the end of the first extension (222) and may include a metal plate (224a) and a connecting part (224b).

[0059] The metal plates (224a) may be provided in multiple numbers and spaced apart from each other at predetermined intervals. Accordingly, a gap may be formed between the multiple metal plates (224a), and air heated by the antenna (230) may pass through the gap between the metal plates (224a) to facilitate heat exchange.

[0060] Meanwhile, as the number of metal plates (224a) increases, the heat dissipation efficiency improves. Therefore, the number of metal plates (224a) can be increased by forming the end of the first extension part (222) to widen in the direction in which the heat exchange part (224) is arranged.

[0061] The connecting portion (224b) is a part that is in direct contact with the antenna (230) and can connect the outer end of the metal plate (224a). For example, the connecting portion (224b) may be formed such that one side (224c) to which the antenna (230) is fixed has a slope inclined at a predetermined angle. In this way, as the one side (224c) of the connecting portion (224b) to which the antenna (230) is fixed is formed to have a slope, the contact area with the antenna (230) is increased, thereby improving heat dissipation efficiency.

[0062] Referring to FIGS. 4 to 6, the heat dissipation member (220) may further include an eccentricity prevention member (270) to prevent the heat dissipation member (220) from tilting and becoming eccentric when the actuator (240) rotates.

[0063] The eccentricity prevention member (270) is provided on the second extension part (223) and may be positioned facing the heat exchange part (224). For example, the eccentricity prevention member (270) may be positioned spaced apart from the actuator (240) so as not to interfere with the actuator (240) when the heat dissipation member (220) rotates.

[0064] In this way, as the second extension part (223) is provided with an eccentricity prevention member (270), it is possible to prevent the heat dissipation member (220) from tilting to one side due to the weight of the heat exchange part (224). That is, the left and right balance of the heat dissipation member (220) can be adjusted through the eccentricity prevention member (270). At this time, by providing the eccentricity prevention member (270) so that it can be detachably attached from the second extension part (223), the eccentricity prevention member (270) can be replaced according to the weight of the heat dissipation member (220).

[0065] The eccentricity prevention member (270) may be formed from the same metal material as the heat dissipation member (220). For example, the eccentricity prevention member (270) may be formed from a metal material such as copper, aluminum, or nickel, which has good thermal conductivity. Accordingly, since the eccentricity prevention member (270) can perform heat exchange together with the heat dissipation member (220), the heat dissipation efficiency of the control box (200) can be improved.

[0066] The heat exchanger (224) and the eccentricity prevention member (270) may be spaced apart from the support plate (214). That is, by spaced the heat exchanger (224) and the eccentricity prevention member (270) apart from the support plate (214) at a certain distance, interference between the heat exchanger (224) and the eccentricity prevention member (270) and the support plate (214) during rotation can be prevented. As the heat exchanger (224) and the eccentricity prevention member (270) are spaced apart from the support plate (214) at a certain distance, a gap (G) may be formed in the lower part of the heat exchanger (224).

[0067] FIG. 7 is a side view illustrating the state of the heat dissipation member according to the presence or absence of the eccentricity prevention member during rotational driving.

[0068] Referring to FIG. 7, in the case of a heat dissipation member (220) that is not equipped with an eccentricity prevention member (270), the heat dissipation member (220) may tilt to one side due to the weight of the heat exchanger (224), and the gap (G) between the support plate and the heat exchanger (224) may not be uniform. However, when the heat dissipation member (220) is equipped with an eccentricity prevention member (270), the left and right balance of the heat dissipation member (220) is maintained, and the gap (G') between the support plate (214) and the heat exchanger (224) can be maintained uniformly. Therefore, when the eccentricity prevention member (270) is equipped, it is possible to prevent eccentricity from occurring during rotation, so rotational driving can be made smoother.

[0069] Referring to FIGS. 4 to 6, the actuator (240) may include a motor (241), a flange shaft (242), and a bearing (243).

[0070] The motor (241) may be placed within the receiving space (210a) and may be provided as a servo motor or a stepping motor. For example, the motor (241) may be connected to the heat dissipation member (220) via a flange shaft (242). Due to this connection structure, when the motor (241) is rotated, the heat dissipation member (220) and the antenna (230) provided on the heat dissipation member (220) may also rotate.

[0071] The flange shaft (242) can be coupled to the rotation axis of the motor (241). For example, the flange shaft (242) can be formed to surround the rotation axis of the motor (241) and can be coupled to the lower part of the heat dissipation member (220) through a fastening member such as a bolt.

[0072] A bearing (243) can be coupled to the outer surface of a flange shaft (242). In order to prevent the bearing (243) from detaching from the flange shaft (242), the flange shaft (242) includes a support portion (242a) protruding outward from the lower end, and the bearing (243) can be seated on the support portion (242a).

[0073] The bearing (243) can rotatably support a portion of the lower side of the heat dissipation member (220). Due to the configuration of the bearing (243), the friction coefficient between the heat dissipation member (220) and the motor (241) can be reduced, thereby minimizing the rotational friction force of the motor (241). Accordingly, compared to the case where the motor (241) and the heat dissipation member (220) are directly coupled without the bearing (243), the heat dissipation member (220) can rotate more with the same power of the motor (241).

[0074] In addition, since a reduction gear such as a spur gear is not provided when the actuator (240) is rotated, the heat dissipation member (220) can be rotated at a high speed. By omitting such a reduction gear, the control box (200) can be made slimmer.

[0075] FIG. 8 is a plan view of a heat dissipation member and an actuator according to one embodiment of the present invention, and FIG. 9 is a cross-sectional view of AA of FIG. 8.

[0076] Referring to FIGS. 8 and 9, the actuator (240) may further include a cover member (244).

[0077] The cover member (244) is fixed within the case (210) and can cover the actuator (240) at the bottom of the heat dissipation member (220). For example, the cover member (244) may be formed of POM material and may include a first body part (244a) that encloses a part of the actuator (240) and a second body part (244b) that encloses the remainder of the actuator (240).

[0078] The cover member (244) can be coupled to the support plate (214), and a hollow can be formed inside to accommodate the actuator (240). Additionally, a step (244c) for supporting a part of the flange shaft (242) can be provided on the upper inner surface of the cover member (244) (see FIG. 6).

[0079] Meanwhile, when the cover member (244) and the heat dissipation member (220) are arranged to be in contact, the heat dissipation member (220) may interfere with the cover member (244) when rotating, and rotation may not proceed smoothly. Therefore, the heat dissipation member (220) must be spaced apart from the cover member (244) at a certain distance. However, this spaced gap between the cover member (244) and the heat dissipation member (220) causes flow in the up-and-down direction when the heat dissipation member (220) rotates, and this may be a cause affecting wireless sensitivity.

[0080] To solve this problem, a plurality of support protrusions (244d) that support the heat dissipation member (220) may be spaced apart on the upper part of the cover member (244). That is, the support protrusions (244d) can support the heat dissipation member (220) together with the bearing (243). For example, the heat dissipation member (220) may be positioned outside the bearing (243) and may be formed in a dome shape with a convex upper surface. Such dome-shaped support protrusions (244d) can prevent flow from occurring when the heat dissipation member (220) rotates, while minimizing the influence on the rotational force of the heat dissipation member (220).

[0081] According to the present invention, the control box (200) may further include a sensor module (280) for detecting the amount of rotation of an antenna (230) provided in a heat dissipation member (220). For example, the sensor module (280) may include a rotating plate (281) and a sensor part (282).

[0082] The rotating plate (281) is coupled to the lower part of the heat dissipation member (220), and a circular hollow (281a) may be formed so that an actuator (240) is located inside.

[0083] The sensor unit (282) is positioned in the hollow (281a) of the rotating plate (281) and can measure the amount of rotation of the rotating plate (281). For example, the sensor unit (282) may be provided as a displacement sensor. The sensor unit (282) may be coupled to the cover member (244) and positioned to face the rotating plate (281), and the amount of rotation of the antenna (230) can be detected by measuring the amount of rotation of the rotating plate (281). That is, since the rotating plate (281) rotates together with the heat dissipation member (220) equipped with the antenna (230), the amount of rotation of the antenna (230) can be detected by measuring the amount of rotation of the rotating plate (281) through the sensor unit (282).

[0084] FIG. 10 is a diagram showing a state in which a heat dissipation member according to one embodiment of the present invention is driven to rotate in both directions by an actuator.

[0085] Referring to FIG. 10, the heat dissipation member (220) can be rotated clockwise and counterclockwise by an actuator (240). For example, the heat dissipation member (220) can be formed to have a rotation radius of 270° by the actuator (240) while its position is fixed on the support plate (214). That is, the heat dissipation member (220) can rotate 135° clockwise and 135° counterclockwise in its initial fixed position. The rotation radius of the heat dissipation member (220) is not limited to that illustrated.

[0086] Meanwhile, the heat dissipation member (220) may take about 4 to 6 seconds to complete one rotation at the maximum rotation radius. For example, if the maximum rotation radius of the heat dissipation member (220) is 270°, the heat dissipation member (220) may complete one rotation along the rotation radius in 5 seconds.

[0087] As described above, the wireless display system (1) can improve usability by automatically controlling the rotation direction of the antenna (230) through an actuator (240) provided inside the control box (200).

[0088] In addition, since the antenna (230) is rotated while coupled to the heat dissipation member (220), the heat generated from the antenna (230) can be discharged more quickly and efficiently.

[0089] In addition, by providing an eccentricity prevention member (270) to balance the left and right sides when the heat dissipation member (220) is rotated, it is possible to prevent the heat dissipation member (220) from tilting during rotation.

[0090] In addition, since the actuator (240) does not require a reduction gear such as a spur gear, the rotational speed of the antenna (230) can be increased.

[0091] Additionally, by including a bearing (243) that allows the actuator (240) to rotatably support the heat dissipation member (220), the rotational speed of the antenna (230) can be improved by stably supporting the heat dissipation member (220) rotating at high speed while minimizing the rotational friction of the motor (241).

[0092] The embodiments of the present invention described above are briefly explained as follows.

[0093] According to embodiments of the present invention, a control box for a display device may be provided, comprising a case having an internal receiving space, a heat dissipation member rotatably disposed in the receiving space, an antenna fixed to the heat dissipation member, and an actuator coupled to the heat dissipation member and rotating the heat dissipation member equipped with the antenna.

[0094] According to embodiments of the present invention, the heat dissipation member may include a heat exchanger comprising a connecting plate coupled to an actuator, a first extension extending from one end of the connecting plate, a second extension extending from the other end of the connecting plate, and a plurality of metal plates disposed at the end of the first extension and spaced apart from each other at a predetermined interval.

[0095] According to embodiments of the present invention, the heat exchanger further includes a connecting portion connecting the ends of the metal plates, and the connecting portion may have a slope in which one surface on which the antenna is fixed is inclined at a predetermined angle.

[0096] According to embodiments of the present invention, an eccentricity prevention member may be provided in a second extension and positioned facing the heat exchanger.

[0097] According to embodiments of the present invention, the eccentricity prevention member may be detachably provided to the second extension.

[0098] According to embodiments of the present invention, the eccentricity prevention member may be spaced apart from the actuator so as not to interfere with the actuator.

[0099] According to embodiments of the present invention, the anti-eccentricity member may be formed of the same metal material as the heat dissipation member.

[0100] According to embodiments of the present invention, the device includes a support plate disposed in a receiving space of a case and coupled to an actuator, and the heat exchanger and the eccentricity prevention member may be spaced apart from the support plate.

[0101] According to embodiments of the present invention, the actuator may include a motor disposed within a receiving space and connected to a heat dissipation member, a flange shaft coupled to the rotation axis of the motor, and a bearing coupled to the outer surface of the flange shaft and rotatably supporting the heat dissipation member.
