Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an actuator for a headlamp,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an actuator for a vehicle headlamp, and more particularly to a swivel-type actuator used for automatically adjusting a beam of a headlamp from side to side.

Generally, the vehicle is provided with a head lamp, so that it can be operated while confirming the course ahead in the daytime or nighttime in which the field of view is not secured.

The vehicle headlamps have different angles at which the beams of the right and left lamps are irradiated depending on the road network of each country. A left-hand drive (LHD) vehicle is designed such that the beam of the lamp is directed further to the right of the traveling direction centered on the road's centerline. On the other hand, a right-hand drive (RHD) vehicle is designed such that the beam of the lamp is irradiated farther to the left of the traveling direction about the center line of the road.

Recently, Adaptive Front-Lighting System (AFS) technology has been commercialized that automatically adjusts the direction of the headlamp according to the angle and direction of the vehicle's steering wheel.

The key components in AFS are a leveling actuator that adjusts the beam up and down and a swivel actuator that adjusts the beam from side to side. The leveling actuator and the swivel actuator must accurately connect each signal transmission element to receive the control signal correctly.

As shown in FIG. 1, a conventional actuator for a vehicle headlamp includes a device case 20 and a printed circuit board 30 which are sequentially arranged along one side of the housing 10.

The element case 20 has an upper output pin 22 and a connection slot 24 therein. Here, the element case 20 is provided with an auxiliary printed circuit board (not shown) therein to mount the phase output pin 22 and the connection slot 24.

The printed circuit board 30 is disposed adjacent to the element case 20, and various elements for controlling the actuator are mounted. The printed circuit board 30 is mounted on the housing 10 through the connecting bracket 32. [

One end of the connection bracket 32 is connected to the housing 10 while surrounding the side surface of the device case 20 and the other end is attached to the upper surface of the printed circuit board 30. [

However, when the connection bracket 32 is made of iron and the motor is driven, the actuator for the headlamp of the present invention can be mounted on the printed circuit board 30, The circuit board 30 causes noise and vibration due to mounting in the housing 10. [

Also, due to the radial noise generated by the motor, there is a problem that the characteristic value is not satisfied because it exceeds the reference value in the CE state and RE state. Furthermore, there is a problem that when the motor is driven, noise and vibration are generated in comparison with the reference value in the head lamp setting state.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an actuator for a vehicle headlamp capable of preventing noise and vibration generated when a printed circuit board is mounted on a housing even when a motor is driven.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not intended to limit the invention to the precise form disclosed. There will be.

In order to accomplish the above object, the actuator for a vehicle headlamp according to the present invention comprises a housing, a device seating part provided on one side of the housing, and a substrate support extended to one side of the device seating part to support the printed circuit board And the printed circuit board is seated and supported together with the element seating portion and the substrate support.

In one embodiment, the device seating portion includes a guide member for guiding one side of the printed circuit board along a side surface thereof. Here, it is preferable that the guide member has a U-shaped structure along the side surface of the device seating portion.

In one embodiment, the substrate support includes a plurality of support members extending on both sides of the center portion at regular intervals to support the edges of the printed circuit board, and a plurality of support members disposed adjacent the support member and penetrating the printed circuit board And includes a plurality of protrusions to be connected. The support member may be provided with a hook for hooking the upper end of the printed circuit board.

According to the actuator for a vehicle headlamp according to the present invention, the printed circuit board is seated on the element seating portion and the substrate support, and the neck portion of the printed circuit board is guided by the guide member formed on the element seating portion, It is possible to prevent the member from moving back and forth / right and left by the projection and the member.

Therefore, it is possible to prevent noise and vibration from occurring in the head lamp setting state when the motor is driven, compared with the reference value. In addition, the printed circuit board is firmly mounted on the housing, thereby enhancing the durability and reliability of the actuator.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. The definitions of these terms should be interpreted based on the contents of the present specification and meanings and concepts in accordance with the technical idea of the present invention.

FIG. 2 is a partially exploded perspective view showing a swivel type actuator according to an embodiment of the present invention, and FIG. 3 is an enlarged view showing part A of FIG.

2 and 3, the swivel type actuator according to an embodiment of the present invention includes a housing 100, a device seating part 110 provided on one side of the housing 100, And a substrate support 120 extending to one side of the seating portion 110.

The device seating part 110 includes a power connection pin 112 and a connection slot 114 to connect an auxiliary printed circuit board (not shown) and an upper output pin (not shown). 4, a guide member 116 for guiding one side of the printed circuit board 130 is formed along the side surface of the element seating portion 110. As shown in FIG. Here, the guide member 116 is formed in a C-shape along the side surface of the element seating portion 110 so as to surround one side or neck of the printed circuit board 130.

The substrate support 120 includes a plurality of support members 122 extending at both sides of the center portion at regular intervals and a plurality of protrusions 124 disposed adjacent to the support member 122.

The supporting members 122 are provided on the left and right in a single pair so as to support the edges of the printed circuit board 130. The support member 122 is provided at its distal end with a hook portion 122a for gripping the top end of the printed circuit board 130, respectively. Here, the support member 122 serves to support the edge of the printed circuit board 130 and support the substrate support 120 in an unobtrusive manner.

As shown in FIG. 4, the protruding portion 124 is disposed adjacent to the support member 122 and connected to the printed circuit board 130 through the protruding portion 124. Here, the protrusions 124 prevent the PCB 130 from flowing to the left and right.
