Description

Adaptive driving beam module {adaptive driving beam module}

The present invention relates to an adaptive driving beam module, and more particularly, to an adaptive driving beam module developed to implement multiple functions of an ADB headlight (Adaptive Driving Beam Headlamp) installed in a vehicle as a single module.

In general, lamp devices such as headlamps, tail lamps, fog lamps, direction indicator lamps, etc., which are unit-type headlamps, are installed in automobiles. In particular, headlights are important lighting devices in automobiles, and are installed on both left and right sides of the front of the automobile. It is a kind of device that enables the vehicle to drive safely by illuminating the front during night driving.

These headlamps are evolving into a system in which light is projected adaptively on a road and surrounding environment from a method in which light is passively illuminated according to the development of science and technology.

That is, evolving vehicle headlights provide bright light on a dark road, but may provide dark light on a bright road. In addition, it is also developed in the form of an automatically adjusted system (eg GFHB, Glare Free High Beam) to minimize glare to drivers of oncoming cars.

Issues that are currently being reviewed or developed for automobile headlights include, for example, night driving enhancement systems, new light sources, high efficiency and eco-friendliness, optical measurement methods, and visual and physiological response technologies.

ADB headlamp according to the prior art is a representative system for improving nighttime driving in which a video image processing technology of a front camera and a control technology of a light source module are combined.

Such a conventional ADB headlamp basically has at least two actuators to independently rotate and control a dipped beam (e.g., the first optical system), a high beam (e.g., the second optical system), and a GFHB (e.g., the third optical system). are mounted in different locations. For example, the second optical system and the third optical system may be operated by any one of the two actuators for a swivel operation (eg, left and right rotation). In addition, since the conventional ADB headlamp uses separate actuators for leveling (e.g., vertical rotation) of the first to third optical systems, a total of three actuators installed at three different locations are required.

However, in the prior art, when only one ADB headlamp is mounted on the headlamp unit, the dipped beam pattern also moves according to the swivel motion, resulting in changes in road surface illumination at a short distance, which is unfavorable for securing visibility.

In addition, in the prior art, there are cases in which two or more (eg, four) ADB headlamps are mounted on a headlamp unit, and in this case, it is advantageous to maintain road surface illumination and form various types of beam patterns or light distribution patterns. Alternatively, it can be changed, so that light can be actively irradiated to the road and the surrounding environment more delicately, but an increase in the number of actuators for the corresponding ADB headlight, an increase in actuator assembly points, and an increase in cost are inevitable, and a plurality of actuators are used as a headlamp unit It becomes very difficult to assemble or install inside the housing of

Thus, in the prior art, it is very difficult to assemble and accommodate actuators or modules for corresponding operations, such as motors and gears for swiveling and leveling operations, individually in the limited internal space of the unit.

In addition, in the prior art, the overall volume and weight of the headlamp unit increase, and the increase in the number of parts causes an increase in the total cost, and wiring for electrically connecting the motors installed for each operation to each other or controlling each motor The control board for this can also solve the increasing problem, and the development of a relatively miniaturized integrated module is urgently requested.

An object of the present invention is proposed in view of the above situation, and by mounting multiple functions (eg, independent swivel operation and leveling operation) related to an ADB (Adaptive Driving Beam) headlight in one casing, ADB headlight Not only can the plurality of optical systems provided in the overall implementation of the leveling operation, but also the swivel operation of the corresponding optical system (e.g., low beam and high beam and GFHB (Glare Free High Beam)) can be implemented individually or independently, It is an object of the present invention to provide an adaptive driving beam module that can be relatively or cost competitive than using a plurality of modules for each optical system.

An adaptive driving beam module according to one aspect of the present invention for achieving the above object includes a first swivel shaft for swiveling a side optical system disposed inside a housing of a vehicle lighting device by a motor driving force, and a first side optical system. The first swivel shaft is inserted and disposed in the same direction as the axial extension direction of the first swivel shaft so that the other side optical system disposed below is independently swiveled by another motor driving force. A module body having a hollow second swivel shaft surrounding an outer circumferential surface of the module body; and an optical unit including a frame in which the one side optical system connected to the first swivel shaft of the module body and the other side optical system connected to the second swivel shaft are accommodated to be spaced apart from each other in a vertical direction.

A coupler is interposed between the optical unit and the module body so as to attachably connect the frame of the optical unit and the casing of the module body.

The module body further accommodates in the casing a control board that is connected to an upper control unit (Electronic Control Unit) provided in the vehicle and controls the operation of a motor or a light source corresponding to an internal component of the module body.

The casing, as an enclosure structure, has a hollow space with an open bottom and includes a cover coupled to the open bottom rim of the enclosure to be attachable.

The casing may include a gear hole formed at one side of the upper surface of the casing to pass a fixed bevel gear for leveling operation; and a swivel shaft hole formed on the other side of the upper surface of the casing to pass the first swivel shaft and the second swivel shaft.

The module body may include: a first motor disposed inside a casing forming an outer periphery of the module body, supported on an inner surface of the casing, and having a first motor shaft directed toward a cover coupled to the casing; first reduction gears meshed between the first motor shaft and the first swivel shaft so that the motor driving force of the first motor is transmitted; and a first bearing block rotatably supporting the first swivel shaft based on the casing.

The module body includes a second motor supported on one side of an internal partition wall formed inside the casing and having a second motor shaft facing the opposite side of the cover; second reduction gears meshed between the second motor shaft and the second swivel shaft so that the motor driving force of the second motor is transmitted; and a second bearing block rotatably supporting the second swivel shaft based on the casing.

The second reduction gears may include a second driving gear axially coupled to the second motor shaft; a second idle gear axially coupled to a hanger shaft rotatably coupled to the ceiling surface of the casing while being engaged with the second drive gear; and a second driven gear geared to the second idle gear and shaft-coupled to the second swivel shaft.

The module body may include a third motor supported on the other side of the inner partition wall of the casing and having a third motor shaft facing the cover; third reduction gears engaged between the third motor shaft and the bevel shaft so that the motor driving force of the third motor is transmitted; a third bearing block rotatably supporting the bevel shaft based on the casing; and a rotating bevel gear that is axially coupled to the bevel shaft based on a position opposite to the position where the third reduction gears are located and is disposed below the gear hole of the casing to engage with the fixed bevel gear.

The optical unit may include one side optical system rotatably disposed on an inner upper side of the frame; and the other side optical system rotatably disposed at the inner lower side of the frame, wherein the first optical system, which is the one side optical system, has a first light source mounted thereon and has an end of the first swivel shaft extending from the module body. A first swivel body connected to, a first reflector disposed above the first light emitting source and connected to the first swivel body, and formed on the upper side of the first swivel body, so that the ceiling of the frame A third optical system including a pivot part hinged to the hole and being one of the other optical systems includes a boss on which a third light emitting source is mounted and connected to an end of the second swivel shaft extending from the module body; A second swivel body in which the boss is integrally formed, a third reflector disposed under the third light emitting source and connected to the second swivel body, and the boss connected to the end of the second swivel shaft.

Unlike the prior art, the adaptive driving beam module according to the present invention can drive multiple optical systems as a single device, and as a multi-function actuator, the housing of a vehicle lighting device (eg, headlight or headlamp unit) can be made relatively small. Therefore, the installation space of the housing of the lighting device can be minimized and the assembly process can be simplified.

The adaptive driving beam module according to the present invention can independently control the rotation (swivel) of the first optical system (eg, low beam) and the second and third optical systems (eg, high beam and GFHB). In the prior art, two actuators were required to independently control the first optical system and the second and third optical systems. However, in the present invention, the leveling operation can be performed without additional installation of a separate actuator for leveling operation while implementing the same function with one module. There are advantages to doing it.

In addition, in the adaptive driving beam module according to the present invention, since the first optical system and the second and third optical systems independently perform a swiveling operation (eg, rotational movement), the operation of one optical system (eg, the first optical system) is affected by the operation of the other optical system (eg, the first optical system). : Optimal ADB characteristics can be realized without affecting the characteristics of the second and third optical systems).

That is, in the adaptive driving beam module according to the present invention, the first optical system of one optical unit can be fixed to correspond to the beam pattern through the control of one multifunctional module body, and the second and third optical systems, which are high beam or GFHB Since can be swiveled, it is possible to prevent a change in illumination of a road surface at a short distance and has an advantage in securing a field of vision.

It consists of a first driven gear 114 axially coupled to the first swivel shaft 110 while being connected). Since the size of the first driven gear 114 is larger than that of the first driving gear 113, deceleration performance according to the gear ratio may be generated. The swivel operation of the first optical system 210 connected to the first swivel shaft 110 can be precisely performed by this deceleration performance.

The first reduction gears 113 and 114 are disposed at the lower end of the first swivel shaft 110, and the first bearing block 115 is disposed above the first reduction gears 113 and 114.

The leveling central axis 202 may play a role of rotatably supporting the module body 100 and the optical unit 200 in a cantilever type based on the housing 10 of the headlamp unit when looking only at its own structure. .

The first reduction gears 113 and 114, the second reduction gears 121, 122, and 123, and the third reduction gears 143 and 144 have a zigzag structure inside the casing 130 to maximize space utilization.
