[0004] The present embodiment provides a vehicle display device capable of swinging a display module with high reliability with a simple structure.

[0005] The present embodiment provides a vehicle display device capable of minimizing distortion of the position or angle of a swivel frame placed on a display module.

[0006] The present embodiment provides a vehicle display device in which a swivel frame rotates around a virtual axis with a fixed position so that a display module can swing more stably.

[0007] A vehicle display device according to the present embodiment may include a fixed frame; a swivel frame disposed on a display module and having a driven rack formed thereon; a driving pinion engaged with the driven rack; and a driving source for rotating the driving pinion.

[0008] A guide path can be formed in either the fixed frame or the swivel frame.

[0009] One of the fixed frame and the swivel frame may have a guide pin positioned thereon to guide the guide path.

[0010] The swivel frame can be rotated around a virtual axis. The virtual axis can be positioned on the display module.

[0011] A vehicle display device may further include an auxiliary guide path formed in one of a fixed frame and a swivel frame; and an auxiliary guide pin disposed in the other of the fixed frame and the swivel frame and guided by the auxiliary guide path.

[0034] According to this embodiment, when the driving pinion drives the driven rack, the guide path guides the guide pin, so that the position or angle of the swivel frame can be minimized from being distorted.

[0035] In addition, the swivel frame can be stably rotated around the virtual axis, and malfunction of the swivel frame can be minimized.

[0036] In addition, the swivel frame can reliably swing around a virtual axis with a simple structure of a driving pinion, a driven rack, a guide path, and a guide pin, without the need for a driving link, nut, lead screw, etc. for swinging the swivel frame.
