Beam projector apparatus for vehicle
The present disclosure relates to a beam projector apparatus for a vehicle, in which a beam projector installed on an armrest of a rear seat may be used to project a video onto a screen provided in a vehicle and enable a vehicle passenger to watch the video in a situation in which the vehicle passenger takes a rest, and as necessary, the projector may be taken out of the armrest and used in an outdoor resting space outside the vehicle to allow a user to watch a video.
1. A beam projector apparatus for a vehicle, the beam projector apparatus comprising:
a projector configured to provide a video; and
a tray box configured to accommodate the projector,
wherein the tray box is installed on an armrest of a rear seat, wherein the tray box is opened at an upper side thereof to receive or withdraw the projector, an upper cap is coupled to the opened upper side of the tray box, and a slide door is coupled to the upper cap and opens or closes the tray box.
2. The beam projector apparatus of claim 1 , wherein the video from the projector is projected forward from the tray box installed on the armrest in a state in which the armrest rotates and protrudes forward from a seatback.
3. The beam projector apparatus of claim 1 , wherein an armrest frame is installed on the armrest and the tray box is fixedly on the armrest frame.
4. The beam projector apparatus of claim 1 , wherein a video projection part is provided on a front surface of the tray box and serves as a passageway through which the video from the projector is projected.
5. The beam projector apparatus of claim 4 , wherein a front cover configured to open or close the passageway of the video projection part is installed on the video projection part to protect a lens of a projector.
6. The beam projector apparatus of claim 1 , further comprising:
a cooling fan installed in the tray box and configured to discharge heat to the outside of the tray box.
7. The beam projector apparatus of claim 6 , wherein a fan guide is installed on a rear surface of the tray box, and the cooling fan is installed in the fan guide.
8. The beam projector apparatus of claim 1 , wherein the projector accommodated in the tray box is configured to be taken out of the tray box in the armrest and used outside a vehicle.
9. The beam projector apparatus of claim 1 , wherein the projector accommodated in the tray box is installed to be positioned in a front internal space of the armrest to project the video.
10. The beam projector apparatus of claim 1 , further comprising:
an adapter installed in the tray box such that the projector is docked on the adapter to charge the projector and transmit or receive data.
11. The beam projector apparatus of claim 10 , wherein a height of the adapter is adjustable in an upward and downward direction, and a video output angle of the projector is changed when the height of the adapter is adjusted.
12. The beam projector apparatus of claim 10 , wherein the adapter is installed so that a height of the adapter is adjustable in an upward and downward direction by a height adjustment mechanism, and
wherein the height adjustment mechanism comprises:
a driving dial rotatably installed on the tray box and configured to be operated by a user;
a driven dial rotatably installed on the tray box and configured to rotate by receiving a rotation of the driving dial through a belt; and
an operation bar installed such that one end is coupled to a position disposed eccentrically from a center of the driven dial, and the other end thereof is in contact with a lower surface of the adapter.
13. The beam projector apparatus of claim 12 , wherein the other end of the operation bar is in contact with a lower surface of a front side of the adapter, and a height of the adapter is adjusted as the front side of the adapter moves upward or downward in a state in which a rear side of the adapter is in contact with the tray box when the operation bar is moved by a rotation of the driven dial.
14. The beam projector apparatus of claim 1 , wherein the video provided from the projector installed on the armrest is projected onto a screen provided in a vehicle interior, for passenger viewing.
15. A beam projector apparatus for a vehicle, the beam projector apparatus comprising:
a projector configured to provide a video; and
a tray box configured to accommodate the projector,
wherein the tray box is installed on an armrest of a rear seat, wherein the tray box is opened at an upper side thereof to receive or withdraw the projector, and a rotary door is installed on an upper portion of the tray box and opens or closes the tray box.
16. A beam projector apparatus for a vehicle, the beam projector apparatus comprising:
a projector configured to provide a video; a tray box configured to accommodate the projector,
wherein the tray box is installed on an armrest of a rear seat; and
an adapter installed in the tray box such that the projector is docked on the adapter to charge the projector and transmit or receive data, wherein a height of the adapter is adjustable in an upward and downward direction, and a video output angle of the projector is changed when the height of the adapter is adjusted.
17. The beam projector apparatus of claim 16 , wherein the adapter is installed so that a height of the adapter is adjustable in an upward and downward direction by a height adjustment mechanism, and
wherein the height adjustment mechanism comprises:
a driving dial rotatably installed on the tray box and configured to be operated by a user;
a driven dial rotatably installed on the tray box and configured to rotate by receiving a rotation of the driving dial through a belt; and
an operation bar installed such that one end is coupled to a position disposed eccentrically from a center of the driven dial, and the other end thereof is in contact with a lower surface of the adapter.
18. The beam projector apparatus of claim 17 , wherein the other end of the operation bar is in contact with a lower surface of a front side of the adapter, and a height of the adapter is adjusted as the front side of the adapter moves upward or downward in a state in which a rear side of the adapter is in contact with the tray box when the operation bar is moved by a rotation of the driven dial.
