Description

Camera devices and vehicles

[0001] This embodiment relates to a camera device and a vehicle.

[0002] Automotive cameras are essential devices for recognizing the vehicle's surrounding environment and performing various functions based on this information. Since automotive cameras are directly exposed to the external environment, their lenses are highly susceptible to contamination by foreign substances such as dust, water droplets, and mud. Lens contamination degrades image quality, which can hinder the accurate implementation of driving assistance and safety functions.

[0003] To address these issues, active research is currently being conducted on technologies to protect automotive camera lenses from contamination or to effectively clean contaminated lenses.

[0004] (Patent Document 1) KR 10-2018-0108024 A

[0006] Furthermore, in this embodiment, a magnet and a coil for high-speed rotation of the cover glass are placed around the lens to provide a camera device with a minimized product size.

[0007] A camera device according to the present embodiment may include a camera module comprising a lens and an image sensor; a stator disposed in the camera module; a rotor rotatably disposed relative to the stator; a bearing disposed between the stator and the rotor; a cover glass coupled to the rotor and covering the lens; and a magnet and a coil for rotating the rotor.

[0008] The above magnet can be superimposed with the coil in the direction of the optical axis of the camera module.

[0009] The stator includes a partition disposed between the magnet and the coil in the direction of the optical axis, and the internal space of the stator where the coil is disposed can be separated from the internal space of the stator where the magnet is disposed by the partition.

[0010] The magnet is formed in a circular ring shape having a hollow, and the camera module can be positioned to pass through the hollow of the magnet.

[0011] The above coil may include a plurality of ring-shaped coil units spaced apart from each other and a connecting coil connecting the plurality of coil units.

[0012] When current is applied to the above coil, the rotor can rotate at a speed of 1,000 to 3,000 rpm.

[0013] The camera device may include a retainer that secures the cover glass to the rotor; and a sealing member disposed between the cover glass, the rotor, and the retainer.

[0014] The above bearing can overlap with the magnet in the direction of the optical axis of the camera module.

[0015] The above bearing may include an inner ring portion, an outer ring portion, a first shield portion and a second shield portion disposed between the inner ring portion and the outer ring portion and spaced apart from each other, and balls disposed between the inner ring portion and the outer ring portion and between the first shield portion and the second shield portion.

[0016] In the direction of the optical axis of the camera module, the length of the bearing may be longer than the length of the magnet.

[0017] The above bearing includes a first sleeve and a second sleeve, at least one of which is in surface contact with each other, and when the rotor rotates, the second sleeve can rotate relative to the first sleeve.

[0018] The magnet and the coil can be placed within the stator.

[0022] Through this embodiment, foreign substances such as dust, water droplets, and mud are prevented from penetrating the lens, and foreign substances attached to the cover glass can also be removed through high-speed rotation.

[0023] Accordingly, accurate driving assistance and safety functions can be implemented even under conditions where visibility is relatively poor, such as driving in the rain.

The bearing (500) may include a first sleeve (560) and a second sleeve (570) having at least one surface in surface contact with each other. When the rotor (300) rotates, the second sleeve (570) may rotate relative to the first sleeve (560). Slip may occur between the second sleeve (570) and the first sleeve (560). A lubricant may be applied between the first sleeve (560) and the second sleeve (570).
