BACKGROUND

1. Field of the Invention

The present invention relates to a vehicle side mirror, and more particularly, to a vehicle side mirror to which a blind spot detection (BSD) module is integrally coupled to monitor a blind spot on a rear lateral side of a vehicle and warn a driver of a danger.

2. Description of the Related Art

As technology becomes more sophisticated, vehicles have been improved in mobility and usability. Recently, warning systems have been incorporated into vehicles to provide a driver with a warning of the potential obstacles in a blind spot while the vehicle is being driven or a possible collision with an approaching vehicle in the blind spot when the driver is changing lanes. For example, a blind spot detection (BSD) system improves driver convenience by warning the driver of an obstacle in a blind spot on a rear lateral side of the vehicle or of an approaching vehicle on the rear lateral side of the vehicle.

FIG. 1 is a detailed view of a vehicle side mirror having a BSD function according to the related art. FIG. 2 is a plan view of the vehicle side mirror having the BSD function according to the related art. FIG. 3 is a cross-sectional view of the vehicle side mirror having the BSD function according to the related art.

Referring to FIGS. 1 and 2, the conventional vehicle side mirror having the BSD function includes a mirror 5 and a mirror holder 10 that supports the mirror 5 and fixes the mirror 5 to a housing (not illustrated). The mirror holder 10 includes an assembly aperture 11 into which a BSD assembly 20 for implementing the BSD function is inserted. Particularly, the BSD assembly 20 may include a lighting unit 21 configured to display a warning signal on the mirror 5 and a wire 27 and a connector 29 configured to deliver power from a power source of a vehicle to the lighting unit 21. The BSD assembly 20 may be detachably coupled to the mirror holder 10, may be coupled to a rear side of the mirror holder 10, and may be exposed on the exterior of the mirror holder 10. In other words, the BSD assembly 20 may be detachably coupled to the mirror holder 10 to be exposed.

Referring to FIG. 3, the lighting unit 21 disposed in the assembly aperture 11 includes a printed circuit board (PCB) 23, a plurality of light sources 24 mounted on the PCB 23, and a lens 25 through which light irradiated from the light sources 24 passes. Since the BSD assembly 20, in particular, the lighting unit 21 is detachably coupled to the mirror holder 10 to be exposed, the lighting unit 21 may move out of position or come loose (e.g., detach) from the mirror holder 10, allowing moisture, etc. to be more easily introduced there into. In addition, since the wire 27 and the connector 29 of the BSD assembly 20 are exposed, these components may also move out of position, detach from the mirror holder 10, or be caught on an object. Further, the detachable BSD assembly 20 creates joints, thus reducing the ease of assembly.

FIG. 4 is a detailed perspective view of a vehicle side mirror 100 according to an exemplary embodiment of the present invention. FIG. 5 is a view of a blind spot detection (BSD)-integrated mirror holder 130 of the vehicle side mirror 100 of FIG. 4. FIG. 6 illustrates the installation state of the BSD-integrated mirror holder 130 of the vehicle side mirror 100 of FIG. 4. Referring to FIGS. 4 through 6, the vehicle side mirror 100 may include a mirror 110, a mirror housing 120, and the BSD-integrated mirror holder 130. The mirror 110 may be installed within the mirror housing 120, and the BSD-integrated mirror holder 130 may be installed between the mirror 110 and the mirror housing 120.

In particular, the BSD-integrated mirror holder 130 supports the mirror 110, and a BSD module 50 configured to provide a warning regarding a danger in a blind spot on a rear lateral side of a vehicle may be disposed in a mounting groove 132 formed in a front surface of the BSD-integrated mirror holder 130 which faces the mirror 110. Since the BSD module 50 may be integrally coupled to the BSD-integrated mirror holder 130, shifting out of position or detaching from the BSD-integrated mirror holder 130 may be prevented. In addition, this structure creates no joints and thus no gaps, thereby blocking the introduction of moisture, etc. Accordingly, watertight performance may be secured.

The BSD module 50 may include a printed circuit board (PCB) 52 installed on an inner surface of the mounting groove 132 of the BSD-integrated mirror holder 130, one or more light sources 54 mounted on a surface of the PCB 52 to irradiate light, and a lens 56 installed in front of the light sources 54 to direct light emitted from the light sources 54 in a predetermined direction.

Particularly, the light sources 54 may be light-emitting diodes (LEDs) which emit excess energy as light when injected electrons and holes recombine. Due to the advantages of low voltage and low power consumption, the LED is being used as a light source for optical coupled devices. The light sources 54 such as LEDs have high energy efficiency (e.g., high light conversion efficiency and low power consumption), have a longer lifespan, and constitute the BSD module 50 with low voltage and low power consumption. In addition, it will be obvious to those of ordinary skill in the art that each of the light sources 54 may be any type of device (e.g., an organic light-emitting diode (OLED) or a laser diode) using an electroluminescent effect.

The BSD module 50 using LEDs as the light sources 54 may provide reduced eye fatigue due to a color temperature of approximately 5500 K, increase the freedom of design due to a minimized size, and is economical due to a semi-permanent life. The light sources 54 such as LEDs may be mounted on the PCB 52 to emit light toward the lens 56. The LEDs may be arranged in an axial direction of the lens 56 to form a desired warning pattern or may be offset to allow a desired amount of light to reach the lens 56. In addition, the PCB 52 may include a terminal (not illustrated) connected to an external power source by a wire 70 and a connector 60. Thus, the PCB 52 may be configured to receive power from a vehicle battery. The PCB 52 may further be configured to supply power to the light sources 54 such as LEDs that convert electrical energy into light energy and operate the light sources 54. Accordingly, a circuit pattern may be formed on the PCB 52.

The lens 56 may have a pattern designed to obtain a desired lighting pattern from the light sources 54 disposed behind the lens 56. The lens 56 may be used to collect light from the light sources 54 and direct the collected light toward the mirror 110 at a predetermined angle. After the lens 56 is mounted in the mounting groove 132 of the BSD-integrated mirror holder 130, a tape or other adhesive may be attached to improve watertightness (e.g., provide a watertight seal). The lens 56 may further include a guide rib 57. The guide rib 57 will be described in detail later.

In addition, the BSD-integrated mirror holder 130 may include the connector 60 and the wire 70 to deliver power to the BSD module 50. Accordingly, a connector insertion groove 134 and a wire insertion groove 136 into which the connector 60 and the wire 70 are respectively inserted may be formed in the BSD-integrated mirror holder 130. The connector insertion groove 134 may be specifically formed in the front surface of the BSD-integrated mirror holder 130 which faces the mirror 110 to be separated from the mounting groove 132 in which the BSD module 50 is disposed. The wire insertion groove 136 may extend between the mounting groove 132 and the connection insertion groove 134.

In particular, the wire insertion groove 136 may extend continuously or discontinuously. The BSD module 50 may be disposed in the mounting groove 132, the connector 60 may be disposed in the connector insertion groove 134, and the wire 70 may connect the BSD module 50 and the connector 60. The wire 70 may be inserted into the wire insertion groove 136 with an end (e.g., a first end) connected to the connector 60 and the other end (e.g., a second end) connected to the PCB 52. In addition, power supplied from a battery (not illustrated) of the vehicle may be delivered to the PCB 52 via the connector 60 and the wire 70. The specific structure of each of the connector insertion groove 134 and the wire insertion groove 136 will be described later.

FIG. 7 is a cross-sectional view of the vehicle side mirror 100 of FIG. 4. Referring to FIG. 7, in the vehicle side mirror 100 according to the current exemplary embodiment, the BSD module 50 may be integrally inserted into the mounting groove 132 of the BSD-integrated mirror holder 130. Therefore, the BSD module 50 may be prevented from moving out of position (e.g., shifting out of position) or detaching from the BSD-integrated mirror holder 130 and from forming joints with other parts. In addition, the lens 56 may include the guide rib 57 which protrudes toward the PCB 52. Particularly, a tip end of the guide rib 57 may be in tight contact with (e.g., may abut) the PCB 52. Therefore, the vehicle side mirror 100 may be assembled more tightly, that is, with an improved airtight or watertight seal. In addition, a tape T, or any other adhesive, may be attached to a region of the lens 56 and a region of the mounting groove 132 of the BSD-integrated mirror holder 130 to eliminate gaps and thus prevent the introduction of moisture, foreign matter, etc. (e.g., improve the seal between the components). Further, since the wire 70, etc. may be prevented from shifting out of position or detaching from the BSD-integrated mirror holder 130, coupling performance may be improved.

FIG. 8 illustrates the mounting groove 132 of the BSD-integrated mirror holder 130 of FIG. 5. Referring to FIG. 8, the mounting groove 132 may be formed in the BSD-integrated mirror holder 130 to integrally couple the BSD module 50 to the BSD-integrated mirror holder 130. The mounting groove 132 may be open on one side, and the BSD module 50 may be mounted in the mounting groove 132 through the open side. In addition, the mirror 110 may be disposed in front of the BSD module 50. Therefore, the BSD module 50 may be integrally coupled to the BSD-integrated mirror holder 130 and may be prevented from being exposed to the exterior. Further, the wire insertion groove 136 into which the wire 70 is inserted may extend from a side of the mounting groove 132 or may be separated from the mounting groove 132 by a predetermined distance.

FIGS. 9A and 9B illustrate the PCB 52 and the light sources 54 mounted in the mounting groove 132 of the BSD-integrated mirror holder 130 of FIG. 8. FIGS. 10 and 11 illustrate the lens 56 and the tape T attached onto the PCB 52 and the light sources 54 mounted in the mounting groove 132 of FIGS. 9A and 9B. Referring to FIGS. 9A and 9B, the PCB 52 on which the light sources 54 are mounted may be disposed in the mounting groove 132 and may be connected to the wire 70. Further, the PCB 52 may be configured to receive power via the wire 70, supply the received power to the light sources 54, and operate the light sources 54. The PCB 52 may be executed by a controller.

In addition, referring to FIGS. 10 and 11, after the PCB 52 is disposed in the mounting groove 132, the lens 56 may be disposed on the PCB 52. Then, the tape T may be attached to fill a gap between the lens 56 and the mounting groove 132. The tape T may also be attached onto the wire 70 connected to the PCB 52, to prevent the introduction of moisture, foreign matter, etc.

FIGS. 12A and 12B illustrate the wire insertion groove 36 of the BSD-integrated mirror holder 130 of FIG. 8 and the wire 70 inserted into the wire insertion groove 136. Referring to FIGS. 12A and 12B, the wire insertion groove 136 may be formed between the connector insertion groove 134 and the mounting groove 132. The wire insertion groove 136 may have a predetermined curvature to prevent the wire 70 from twisting (e.g., becoming tangled).

In addition, the wire insertion groove 136 may further include a plurality of fitting protrusions 137 for coupling and fixing the wire 70 to the wire insertion groove 136. The fitting protrusions 137 may be formed on inner sidewalls of the wire insertion groove 136. The fitting protrusions 137 may be arranged at regular intervals to improve the coupling performance of the wire 70 to prevent the wire 70 from shifting out of position or detaching from the wire insertion groove 136. As described above, the tape T may be attached onto the wire insertion groove 136 and along the wire insertion groove 136 to prevent the introduction of foreign matter, etc.

FIG. 13A illustrates the connector insertion groove 134 of the BSD-integrated mirror holder 130 of FIG. 8. FIGS. 13B and 13C illustrate the connector 60 inserted into the connector insertion groove 134. Referring to FIGS. 13A and 13B, the connector insertion groove 134 of the BSD-integrated mirror holder 130 may further include hook protrusions 135 for coupling and fixing the connector 60 to the connector insertion groove 134. The hook protrusions 135 may be hooked to the connector 60 when the connector 60 is inserted into the connector insertion groove 134. Accordingly, the hook protrusions 135 may improve the coupling performance of the connector 60 to prevent the connector 60 from shifting out of position or detaching from the connector insertion groove 134.

After the BSD module 50 is disposed in the mounting groove 132 of the BSD-integrated mirror holder 130, after the connector 60 is inserted into the connector insertion groove 134, and after the wire 70 is inserted into the wire insertion groove 136, the mirror 110 may be disposed on the front surface of the BSD-integrated mirror holder 130 and then coupled to the mirror housing 120. Accordingly, the BSD module 50, the connector 60, and the wire 70 may be prevented from being exposed to the exterior and thus may be prevented from shifting out of position, detaching from the BSD-integrated mirror holder 130, or the like. Consequently, the coupling performance of each part may be improved.

FIG. 14 illustrates a warning pattern 117 displayed on the vehicle side mirror 100 of FIG. 1. Referring to FIG. 14, in the vehicle side mirror 100 of FIG. 1, a region 115 may be formed by partially etching the mirror 110. The warning pattern 117 formed by the BSD module 50 may be displayed on the region 115 formed by partially etching the mirror 110. The warning pattern 117 may be displayed as an icon that indicates an approaching vehicle but is not limited to the icon as will be obvious to those of ordinary skill in the art.

According to the present invention, a BSD module for monitoring a blind spot on a rear lateral side of a vehicle and providing a warning to a driver of a danger may be integrally coupled to a side mirror to be not exposed.
