Description
Technical Field
The present invention relates to a display device and a headrest assembly, and more particularly, to a display device and a headrest assembly capable of effectively dissipating heat generated by electronic components.
Background
Currently, many car headrests are equipped with a display device. When the display device is in operation, the current in the circuit may generate unnecessary heat due to the impedance, and if the heat cannot be effectively removed and accumulated in the electronic components inside the display device, the electronic components may be damaged due to the continuously increased temperature. The display device installed in the headrest of the car is usually coated with foamed cotton and leather around and on the back side thereof, which is not favorable for heat dissipation. Therefore, how to effectively dissipate heat of the display device mounted on the headrest of the automobile has been a major design issue.
Disclosure of Invention
The invention provides a display device and a headrest combination which can effectively radiate heat of electronic elements, and aims to solve the problems in the prior art.
According to one embodiment, the display device of the invention comprises a shell, a display module, a metal middle frame, a circuit board, an electronic element, a first radiator, a second radiator and a heat pipe. The shell comprises a metal outer frame. The display module is arranged in the shell. The metal middle frame is arranged in the shell and connected to the metal outer frame. The circuit board is arranged on the metal middle frame. The electronic element is arranged on the circuit board. The first radiator is arranged on the electronic element. The second radiator is arranged adjacent to the first radiator, and one end of the second radiator is connected to the metal middle frame. The heat pipe is connected to the first radiator and the second radiator.
According to another embodiment, the headrest assembly of the invention comprises a headrest and a display device. The headrest has a receiving groove. The display device is arranged in the accommodating groove. The display device comprises a shell, a display module, a metal middle frame, a circuit board, an electronic element, a first radiator, a second radiator and a heat pipe. The shell comprises a metal outer frame. The display module is arranged in the shell. The metal middle frame is arranged in the shell and connected to the metal outer frame. The circuit board is arranged on the metal middle frame. The electronic element is arranged on the circuit board. The first radiator is arranged on the electronic element. The second radiator is arranged close to the first radiator, and one end of the second radiator is connected to the metal middle frame. The heat pipe is connected to the first radiator and the second radiator.
In summary, when the electronic components in the display device generate heat energy, a portion of the heat energy may be radiated into the air by the first heat sink, and another portion of the heat energy may be conducted to the second heat sink by the heat pipe. Then, the heat energy can be conducted to the metal middle frame through the second radiator, and then conducted to the metal outer frame of the shell through the metal middle frame. Therefore, heat energy can be dissipated to the air outside the headrest from the metal outer frame of the shell, so that the display device can stably and normally operate in the headrest.
The advantages and spirit of the present invention can be further understood by the following detailed description of the invention and the accompanying drawings.

Detailed Description
Referring to fig. 1 to 5, fig. 1 is a perspective view of a headrest assembly 1 according to an embodiment of the invention, fig. 2 is an exploded view of the headrest 10 and the display device 12 in fig. 1, fig. 3 is an exploded view of the metal frame 1200 and the back cover 1202 in fig. 2, fig. 4 is an exploded view of the first heat sink 130, the second heat sink 132 and the heat pipe 134 in fig. 3, and fig. 5 is a cross-sectional view of the headrest assembly 1 along the X-X line in fig. 1.
As shown in fig. 1 and 2, the headrest assembly 1 includes a headrest 10 and a display device 12. The headrest 10 has a receiving groove 100. The display device 12 may be disposed in the receiving groove 100 of the headrest 10. In practical applications, the headrest 10 may be a car headrest, but not limited thereto. Further, the display device 12 may be a liquid crystal display device or other display device, depending on the actual application.
As shown in fig. 1 to 5, the display device 12 includes a housing 120, a display module 122, a metal bezel 124, a circuit board 126, an electronic component 128, a first heat sink 130, a second heat sink 132, and a heat pipe 134. In this embodiment, the housing 120 may include a metal frame 1200 and a back cover 1202, wherein the back cover 1202 is detachably connected to the metal frame 1200. The display module 122 is disposed in the housing 120. The display module 122 may be a liquid crystal display module or other display modules, depending on the application. In practical applications, the display module 122 may include a touch panel to implement a touch display function.
The metal middle frame 124 is disposed in the housing 120 and connected to the metal outer frame 1200. In this embodiment, the metal middle frame 124 may be made of aluminum, but not limited thereto. The circuit board 126 is disposed on the metal middle frame 124, and the electronic component 128 is disposed on the circuit board 126. In this embodiment, the electronic component 128 may be a Central Processing Unit (CPU), but is not limited thereto. In another embodiment, the electronic component 128 may also be another heat source disposed on the circuit board 126. The first heat sink 130 is disposed on the electronic component 128. The second heat sink 132 is disposed adjacent to the first heat sink 130, and one end of the second heat sink 132 is connected to the metal middle frame 124. In this embodiment, the first heat sink 130 and the second heat sink 132 may include a plurality of heat dissipation fins side by side, but not limited thereto. The heat pipe 134 is connected to the first heat sink 130 and the second heat sink 132. Further, one end of the heat pipe 134 may be connected to the first heat sink 130 and attached to the electronic component 128, and the other end of the heat pipe 134 may be connected to the second heat sink 132, such that the heat pipe 134 may conduct the heat energy generated by the electronic component 128 to the second heat sink 132.
When the electronic component 128 generates thermal energy, a portion of the thermal energy may be radiated into the air by the first heat sink 130, and another portion of the thermal energy may be conducted to the second heat sink 132 by the heat pipe 134. Then, the heat energy can be conducted from the second heat sink 132 to the metal middle frame 124, and then from the metal middle frame 124 to the metal outer frame 1200 of the housing 120. Since the metal outer frame 1200 of the housing 120 is not covered by the headrest 10, the heat generated by the electronic component 128 is conducted to the metal outer frame 1200 of the housing 120 through the heat pipe 134, the second heat sink 132 and the metal middle frame 124, so that the heat can be effectively dissipated from the metal outer frame 1200 of the housing 120 to the air outside the headrest 10. Thereby, the display device 12 can be stably and normally operated in the headrest 10.
As shown in fig. 3 and 5, the back cover 1202 of the housing 120 may have a groove 1204. When the display device 12 is assembled, the first heat sink 130 and the second heat sink 132 are received in the groove 1204 of the back cover 1202. In addition, a plurality of heat dissipation holes 1206 may be formed on a surface of the groove 1204. Since the heat dissipation holes 1206 are close to the first heat sink 130 and the second heat sink 132, the heat of the first heat sink 130 and the second heat sink 132 can be dissipated from the heat dissipation holes 1206 to the outside of the display device 12.
As shown in fig. 5, when the display device 12 is disposed in the receiving groove 100 of the headrest 10, a gap 14 exists between the housing 120 of the display device 12 and the edge of the receiving groove 100 of the headrest 10. Therefore, the heat energy dissipated from the heat dissipating holes 1206 can be further dissipated to the air outside the headrest 10 through the gap 14, thereby enhancing the heat dissipating effect. In addition, a plurality of heat dissipation holes 1208 may be formed around the back cover 1202 of the housing 120. Therefore, the heat energy inside the housing 120 can also be dissipated to the air outside the headrest 10 through the heat dissipation holes 1208 and the gaps 14, thereby enhancing the heat dissipation effect.
Referring to fig. 6, fig. 6 is an internal schematic view of a display device 12' according to another embodiment of the invention. The main difference between the display device 12 'and the display device 12 described above is that the display device 12' further comprises a fan 136, as shown in fig. 6. The fan 136 is disposed on the first heat sink 130. Therefore, the fan 136 can be used to further dissipate heat from the first heat sink 130, thereby improving the heat dissipation effect.
In summary, when the electronic components in the display device generate heat energy, a portion of the heat energy may be radiated into the air by the first heat sink, and another portion of the heat energy may be conducted to the second heat sink by the heat pipe. Then, the heat energy can be conducted to the metal middle frame through the second radiator, and then conducted to the metal outer frame of the shell through the metal middle frame. Therefore, heat energy can be dissipated to the air outside the headrest from the metal outer frame of the shell, so that the display device can stably and normally operate in the headrest. In addition, the heat energy in the display device can also be dissipated to the air outside the headrest through the heat dissipation hole of the back cover and the gaps between the display device and the headrest, so that the heat dissipation effect is improved. Moreover, the invention can be additionally provided with the fan on the radiator so as to further improve the heat dissipation effect by utilizing the fan.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and all equivalent changes and modifications made by the claims of the present invention should be covered by the scope of the present invention.
