Image display device

Abstract

The present disclosure relates to an image display device. In the image display device, electrical connection with a rotating body is reliably maintained during rotation of the rotating body, and supply of power and transmission and reception of signals are stabilized. Since signal transmission and reception between the communication transmitter and the communication receiver are performed through the cavity formed in the motor, introduction of external signals is blocked, thereby ensuring safety and control stability. Even when the rotating module rotates at a high speed, damage caused by friction is prevented, and durability is ensured. The rotation stability of the rotation module is achieved through structural stability.

Description

Technical Field

[0001] The present disclosure relates to an image display device, and more particularly, to an image display device that reliably maintains electrical connection with a rotating body and stably supplies power and transmits and receives signals during rotation of the rotating body. Background Art

[0002] Various technologies for supplying electric power to a continuously rotating device and for transmitting and receiving electric signals are applied in mechanical devices or electronic devices.

[0003] For example, many devices that require electrical connections are used in structures that perform rotational motion, such as rotating lighting devices, LiDAR, antennas, and robots. Wires are connected to the rotating body in order to supply it with power and to send and receive signals.

[0004] However, there may be a problem that the rotating body cannot rotate due to the winding of the electric wire in the rotating direction.

[0005] To solve this problem, a conductor contact type electrical connection structure can be adopted between the rotating body and the fixed body. However, due to the continuous friction between the contact parts, it is difficult to achieve high-speed rotation and ensure durability.

[0006] In particular, in devices where the rotating body needs to rotate at high speed, it is difficult to maintain electrical connection using a conductor contact structure, abnormal noise is generated, and durability deteriorates due to friction over time. In order to achieve high-speed rotation, a mercury slip ring can be used. However, in this case, the use of mercury slip rings may be restricted by heavy metal pollution regulations.

[0039] Hereinafter, an image display device according to an embodiment of the present disclosure is described with reference to the accompanying drawings.

[0040] like Figure 1-5 As shown, the image display device according to the present disclosure includes a fixed module 100, which is fixed on a base B and includes a main controller 110, a motor 120, a communication transmitter 130, and a power transmitter 140. The image display device also includes a rotating module 200, which is rotatably connected to the motor 120 and includes an optical module 210, which provides a plurality of light sources 211a, and the rotating module 200 further includes a communication receiver 230 and a power receiver 240, which are configured to receive commands and power from the main controller 110 to form an illumination image by turning on or off the respective light sources 211a.

[0041] The present disclosure can be applied to various objects, such as mobile vehicles and structures. For example, the present invention can be installed on the roof of a mobile vehicle to display a message through an illuminated image. In this case, the roof of the mobile vehicle can serve as the base B.

[0042] According to the present disclosure, the fixed module 100 is fixed to the base B, and the rotating module 200 forms an illumination image through the optical module 210 while rotating in a state supported by the fixed module 100. In particular, since the rotating module 200 receives command signals and power in a wireless manner, the number of parts of the rotating module 200 that rub against the fixed module 100 can be minimized, so that the high-speed rotation of the rotating module 200 can be stabilized, the reception of command signals and power can be stably maintained, and thus the light image can be stably generated.

[0043] As described above, the fixed module 100 includes the main controller 110 , the motor 120 , the communication transmitter 130 , and the power transmitter 140 , and the rotating module 200 includes the optical module 210 , the communication receiver 230 , and the power receiver 240 .

[0044] The main controller 110 sends command signals for forming a lighting image required by a user or a moving vehicle. In order to control the functions of the main controller 110, the main controller 110 may include a communication device for communicating with other controllers or sensors, a memory storing an operating system, logic commands, and input / output information, and one or more processors for performing judgments, calculations, and determinations required to control the functions of the main controller 110.

[0045] In addition, the main controller 110 is provided with an inverter for converting the direct current transmitted by the mobile vehicle into alternating current. The alternating current converted by the main controller 110 is transmitted to the power transmitter 140. The alternating current applied to the power transmitter 140 generates a magnetic field, and an induced electromotive force is generated to the power receiver 240 included in the rotating module 200 by the change of the magnetic field. The alternating current generated in the power receiver 240 is transmitted to the optical module 210 to turn on or off the light source 211a included in the optical module 210.

[0046] The optical module 210 may include a light source unit 211 in which a plurality of light sources 211a are arranged, and a sub-controller 212 configured to transmit a command of the main controller 110 and power to the light source unit 211. In other words, the light source unit 211 is electrically connected to the sub-controller 212, and the sub-controller 212 is provided with a converter to convert the alternating current transmitted through the power receiver 240 into direct current (DC) power and supply the DC power to each light source 211a of the light source unit 211.

[0047] In this manner, the power transmitted through the main controller 110 and the power transmitter 140 is input to the optical module 210 included in the rotating module 200 through the power receiver 240 and the sub-controller 212, thereby turning on or off each light source 211a.

[0048] In addition, since the rotating module 200 is rotated by the motor 120 included in the fixing module 100 , the rotating module 200 may form an illumination image using an afterimage effect by turning on or off each light source 211 a of the optical module 210 .

[0049] The command signal transmitted from the communication transmitter 130 included in the fixing module 100 is input to the communication receiver 230 included in the rotating module 200, and each light source 211a of the optical module 210 is turned on or off in response to the command signal.

[0050] As described above, according to the present disclosure, the rotating module 200 rotates while being supported by the fixed module 100, and each light source 211a of the optical module 210 included in the rotating module 200 is turned on or off to form an illumination image. Since the rotating module 200 is physically connected to the fixed module 100 through the motor 120, and since the transmission and reception of command signals and power are implemented in a wireless manner, the rotating module 200 can rotate at a high speed, and the durability of the device is improved.

[0051] The above disclosure is described in more detail below. The fixing module 100 may further include a fixing plate 150 and a motor 120 , and the communication transmitter 130 and the power transmitter 140 may be mounted on the fixing plate 150 .

[0052] The rotating module 200 may further include a rotating plate 250 connected to the fixing plate 150 through the motor 120 , and the optical module 210 , the communication receiver 230 , and the power receiver 240 may be mounted on the rotating plate 250 .

[0053] like Figure 2 As shown, the fixing plate 150 included in the fixing module 100 is fixed to the base B, and the fixing plate 150 may be mounted to the base B through a bracket BK, so that the fixing state of the fixing plate 150 may be stabilized.

[0054] The rotating plate 250 included in the rotating module 200 is connected to the fixing plate 150 through the motor 120 .

[0055] The fixed plate 150 and the rotating plate 250 may be formed in a plate shape and may be arranged to face each other. Therefore, the communication transmitter 130 and the power transmitter 140 mounted on the fixed plate 150 face the communication receiver 230 and the power receiver 240 mounted on the rotating plate 250, thereby transmitting and receiving signals and commands between them.

[0056] In addition, the lens cover 300 formed to cover the fixing module 100 and the rotating module 200 may be fixed to the base B.

[0057] The lens cover 300 is made of a transparent material so as to project light emitted by the light source 211a included in the optical module 210 of the rotating module 200 to the outside. In addition, when the lens cover 300 is coupled to the base B to cover the fixed module 100 and the rotating module 200, the lens cover 300 seals the space defined thereby. Therefore, the fixed module 100 and the rotating module 200 disposed in the space defined by the lens cover 300 can be protected from external contamination and impact.

[0058] The shaft 220 may be coupled to a central portion of the rotating plate 250 , and the lens cover 300 may include a rotation support portion 310 to which the shaft 220 is rotatably coupled.

[0059] Since the shaft 220 is coupled to the central portion of the rotating plate 250, the rotating axis of the rotating plate 250 and the rotating axis of the shaft 220 are aligned with each other. Since the shaft 220 is inserted and rotatably connected to the rotating support part 310 formed on the lens cover 300, the rotation of the rotating plate 250 can be stabilized. The rotating support part 310 may be provided with a bearing BR.

[0060] In this manner, the motor 120 is coupled to one side of the central portion of the rotating plate 250, and the rotating plate 250 is rotatably connected to the lens cover 300 through the shaft 220 coupled to the opposite side of the central portion thereof. Therefore, even if the rotating plate 250 rotates at a high speed, the rotating shaft of the rotating plate 250 can be stably maintained, so that the rotation of the rotating plate 250 can be stabilized.

[0061] A plurality of light source units 211 may be provided, and the plurality of light source units 211 may be disposed around the rotating plate 250 so as to be spaced apart from each other. The plurality of light sources 211 a may be arranged in a direction perpendicular to the rotating plate 250 .

[0062] Since the optical module 210 includes a plurality of light source units 211, and the plurality of light source units 211 are arranged around the rotating plate 250 to be spaced apart from each other at regular intervals, an illumination image can be formed by turning on or off a plurality of light sources 211a included in each light source unit 211. In particular, when the light sources 211a included in the light source units 211 are turned on or off in a state in which the rotating module 200 is rotated, if the light source units 211 arranged at fixed intervals are alternately turned on or off, the quality of the illumination image can be improved, thereby improving the visibility of the illumination image.

[0063] In addition, since the plurality of light sources 211 a included in the light source unit 211 are arranged in a direction perpendicular to the rotating plate 250 , the size of the illumination image may correspond to the length by which the light sources 211 a are arranged.

[0064] The motor 120 includes a stator 121 and a rotor 122. The stator 121 may be mounted to the center portion of the fixed plate 150, and the rotor 122 may be connected to the center portion of the rotating plate 250. Therefore, when the motor 120 operates, the rotating plate 250 connected to the fixed plate 150 through the motor 120 may stably rotate about its rotation axis.

[0065] A communication through hole H1 is formed at the center of each of the fixed plate 150 and the rotating plate 250, and each of the stator 121 and the rotor 122 of the motor 120 has a hollow shape formed with a cavity. The communication through hole H1 formed in each of the fixed plate 150 and the rotating plate 250 and the cavity formed in each of the stator 121 and the rotor 122 of the motor 120 define a space in the axial direction.

[0066] The communication transmitter 130 and the communication receiver 230 may transmit and receive signals through the communication through-hole H1 formed in each of the fixed plate 150 and the rotating plate 250 and the cavity formed in each of the stator 121 and the rotor 122 of the motor 120 .

[0067] Therefore, the communication transmitter 130 and the communication receiver 230 are respectively installed at the center of the fixed plate 150 and the center of the rotating plate 250, and are thus arranged to face each other, so that signals are transmitted and received between them through the communication through hole H1 and the cavity in the motor 120. In particular, since the communication transmitter 130 and the communication receiver 230 transmit and receive signals between them only through the communication through hole H1 and the cavity in the motor 120, the introduction of external signals is prevented, thereby ensuring control and safety stability. In addition, since there is no separate wire for transmitting commands through the main controller 110, command signals can be transmitted even when the rotating module 200 rotates.

[0068] Each of the power transmitter 140 and the power receiver 240 is implemented as a coil whose center forms a cavity, and the motor 120 may be disposed at the center of the cavity formed in each of the power transmitter 140 and the power receiver 240 .

[0069] The power transmitter 140 and the power receiver 240 may constitute a wireless power transmission system operating in a magnetic induction manner. In other words, the power transmitter 140 and the power receiver 240 may be implemented as coils, and when current flows through the power transmitter 140, a magnetic field is formed around the power transmitter 140, and power is transmitted to the power receiver 240 through the magnetic field.

[0070] In particular, since each coil forming the power transmitter 140 and the power receiver 240 forms a circle having a cavity at the center, and the motor 120 is disposed at the center of the cavity, it is possible to reduce the installation space of the motor 120, the power transmitter 140, and the power receiver 240. In other words, since the space defined by the center of the coils forming the power transmitter 140 and the power receiver 240 is used as the installation space of the motor 120, the size of the fixed module 100 and the rotating module 200 can be reduced.

[0071] In addition, the fixed plate 150 may be provided with a fixed cover 160 configured to accommodate the power transmitter 140 and open toward the power receiver 240. Similarly, the rotating plate 250 may be provided with a rotating cover 260 configured to accommodate the power receiver 240 and open toward the power transmitter 140.

[0072] The fixed cover 160 and the rotating cover 260 may extend to face each other, and may be spaced apart from each other by a predetermined gap.

[0073] In other words, the fixed cover 160 and the rotating cover 260 are disposed to face each other while covering the power transmitter 140 and the power receiver 240 , respectively, and are open toward each other to enable power transmission and reception between the power transmitter 140 and the power receiver 240 .

[0074] In particular, the remaining parts of the fixed cover 160 and the rotating cover 260 except for the parts opened toward each other are formed to be closed, thereby preventing the peripheral electronic devices from being affected by the magnetic field generated during the power transmission and reception process between the power transmitter 140 and the power receiver 240. In the present disclosure, since the motor 120 is arranged between the power transmitter 140 and the power receiver 240, the motor 120 may malfunction due to the magnetic field generated by the power transmitter 140 and the power receiver 240, and the optical module 210 may be damaged by the magnetic field. Therefore, the power transmitter 140 and the power receiver 240 are covered by the fixed cover 160 and the rotating cover 260 so as to block the magnetic field from being emitted outward during the power transmission and reception process between the power transmitter 140 and the power receiver 240, thereby preventing other electronic components from being adversely affected by the magnetic field.

[0075] In addition, since the fixed cover 160 and the rotating cover 260 extend in a manner facing each other and are spaced apart from each other by a predetermined gap while covering the power transmitter 140 and the power receiver 240 respectively, the rotating cover 260 rotating together with the rotating plate 250 will not contact the fixed cover 160, thereby preventing the fixed cover 160 and the rotating cover 260 from being damaged due to friction.

[0076] In addition, the fixing module 100 and the rotating module 200 may further include a position sensor S to detect the rotation position of the rotating module 200 .

[0077] The position sensor S may include a detection transmitter 170 and a detection receiver 270. The detection transmitter 170 and the detection receiver 270 may be installed on the fixed plate 150 and the rotating plate 250, respectively, and may be disposed to face each other.

[0078] The detection transmitter 170 and the detection receiver 270 may be implemented as capacitive sensors. When the rotating plate 250 rotates under the operation of the motor 120, the position where the detection transmitter 170 and the detection receiver 270 match each other may be detected, and the rotation position of the rotating plate 250 may be determined based on the position. By detecting the rotation position of the rotating plate 250, the rotation speed of the rotating plate 250 may be determined. Based on this information, the turning on or off time of each light source 211a of the optical module 210 may be determined to form an illumination image.

[0079] A plurality of detection transmitters 170 may be provided, and the plurality of detection transmitters 170 may be provided on the fixed plate 150 so as to be spaced apart from each other at regular intervals. A plurality of detection receivers 270 may be provided, and the plurality of detection receivers 270 may be provided on the rotating plate 250 so as to be spaced apart from each other at regular intervals. Therefore, the rotation position of the rotating plate 250 may be accurately detected. In particular, since the plurality of detection transmitters 170 are spaced apart from each other at regular intervals and the plurality of detection receivers 270 are spaced apart from each other at regular intervals, the detection transmitters 170 and the detection receivers 270 may not be biased to any side of each plate, thereby minimizing the rotation resistance of the rotating plate 250.

[0080] In order to install the detection transmitter 170 and the detection receiver 270, each of the fixed plate 150 and the rotating plate 250 may form a detection through hole H2 in its peripheral portion. Therefore, the detection transmitter 170 and the detection receiver 270 may be installed on the fixed plate 150 and the rotating plate 250, respectively, so as to transmit and receive signals therebetween through the detection through hole H2.

[0081] In addition, since the detection through hole H2 is formed in the outer peripheral portion of each of the fixed plate 150 and the rotating plate 250, the arrangement of the detection transmitter 170 and the detection receiver 270 does not interfere with the motor 120, the power transmitter 140, and the power receiver 240. In addition, since the detection transmitter 170 and the detection receiver 270 are located at the farthest position from the center of the rotating plate 250 in the radial direction of the rotating plate 250, the rotation position of the rotating plate 250 can be detected within a sufficient time interval, thereby improving the accuracy of detecting the rotation position of the rotating plate 250.

[0082] The rotating plate 250 and the sub-controller 212 may form a circular shape. In addition, the motor 120, the power transmitter 140, and the power receiver 240 may also be designed in a circular shape.

[0083] Therefore, when the motor 120 is driven, the rotating plate 250 can be stably rotated at a high speed without being biased to one side. In addition, the number of detection transmitters 170 and the number of detection receivers 270 can be the same as each other, and the detection transmitters 170 and the detection receivers 270 can be formed to have the same specifications, thereby ensuring the stable rotation of the rotating plate 250.

[0084] In the image display device configured as above, the rotating module 200 rotates while being supported by the fixing module 100, and each light source 211a of the optical module 210 included in the rotating module 200 is turned on or off to form an illumination image.

[0085] In addition, since the rotating module 200 is physically connected to the fixed module 100 through the motor 120, and transmission and reception of command signals and power are performed wirelessly, high-speed rotation of the rotating module 200 can be achieved and durability of the device is improved.

[0086] As apparent from the above description, according to the image display device configured as above, the electrical connection with the rotating body can be reliably maintained during the rotation of the rotating body, and the supply of electric power and the transmission and reception of signals are stable.

[0087] In addition, since signal transmission and reception between the communication transmitter and the communication receiver are implemented through the cavity formed in the motor, introduction of external signals is blocked, thereby ensuring safety and control stability.

[0088] In addition, even when the rotating module rotates at high speed, damage due to friction is prevented, thereby ensuring durability. In addition, the rotation stability of the rotating module is achieved through structural stability.

[0089] Although the embodiments of the present disclosure have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the disclosure as disclosed in the accompanying claims.
