Description

Technical Field

[0001] The present invention relates to a camera monitor system structure located on a vehicle body panel, to a camera assembly located on the inner side of a vehicle panel and configured to protrude outside the panel according to a user's request, and to a protruding camera monitor system structure including a driving unit and capable of driving the above-mentioned camera assembly by limiting the rotation amount of the camera assembly. Background Art

[0002] Usually, the driver changes lanes by using the interior and exterior mirrors installed in the center front of the car. However, there is a problem as follows: when the driver changes lanes by looking at the exterior mirror in the direction to be changed, an accident may occur with a vehicle traveling in the blind spot or with a vehicle traveling in front.

[0003] In addition, when the vehicle is parked / parked, the conventional exterior rearview mirrors are folded in a state of protruding to the outside, and thus, the exterior rearview mirrors may be damaged by physical impact.

[0004] As a result, CMS (camera mirror system) which displays the external conditions of a vehicle on a screen through an external camera lens has recently attracted much attention.

[0005] As described above, a vehicle using the CMS system is configured such that an external camera protruding to the outside of the vehicle captures the external conditions of the vehicle and the image captured by the external camera is displayed on a display located inside the vehicle.

[0006] As a prior art, the following technology is disclosed: an external camera that rotates and protrudes to the outside of a vehicle, which can be an external camera located on one side of a door, and the external camera is configured to be rotatable toward the inside of the door.

[0007] However, for the external camera inserted into the vehicle door and configured in a protruding manner, even if the external camera is inserted into the vehicle door, it is still exposed in a shape protruding to the outside, and thus there is a risk of damage and theft.

[0008] In addition, for an external camera configured to be introduced into a vehicle door in a folding manner, there is a problem that it is actually difficult to ensure a side rear field of vision because the amount of protrusion thereof is limited.

The control unit 400 can receive sensing data from the processor, can generate control instructions for controlling the controller according to the situation, and can transmit the control instructions to the controller. However, in this specification, for the sake of convenience, the upper processor at the processor level, that is, the ECU processor, is described, but one of the multiple processors belonging to the processor level can perform the function as the ECU, or two processors can be combined to perform the function as the ECU.

[0076] The present invention relates to a camera monitor system stored inside a panel 10 of a vehicle, including a structure that causes at least a portion of the camera monitor system in a stored state to protrude in response to environmental changes during driving or a user's request to provide the user with a side rear view of the vehicle.

[0077] As an embodiment of the present invention, the camera monitor system is located on the panel 10 forming the outer side of the vehicle, and the camera monitor system may be configured to form the outer side of the panel 10 in the stored state.

[0078] In the following, in one embodiment of the present invention, a structure in which the camera monitor system can be stored in the front fender 10 is described, but the installation position of the camera monitor system is not limited thereto and can also be applied to the outer panel 10 of the vehicle to provide a side rear view of the vehicle.

[0079] Figure 1A FIG. 2 shows a state where a camera monitor system according to an embodiment of the present invention is stored in the front fender 10. Figure 1B The camera monitor system is shown in a state of being deployed and protruding toward the outer side surface of the front fender 10 .

[0080] As shown, the camera monitor system located at the front fender 10 is configured to selectively protrude, and the camera assembly 100 located at the rear end of the camera monitor system can protrude opposite to the side rear of the vehicle or opposite to the side lower end of the vehicle.

[0081] On the contrary, when the camera monitor system is stored, the camera monitor system is inserted into the inner side of the front fender 10 and is located so that the outer side surface of the camera monitor system and the outer side surface of the front fender 10 are flush with each other.

[0082] The camera monitor system is configured such that a housing 110 of a camera assembly 100 including a camera unit 120 is rotated with reference to a fixing portion 200 located on the inner side of the front fender 10 to protrude toward the outer side of the front fender 10 .

[0083] More preferably, the fixing portion 200 is fixed to the inner side of the front fender 10. The camera monitor system includes an upper cover 210 located on the upper surface of the fixing portion 200 and configured to be connected to the inner side of the panel 10 by nuts during the assembly stage of the vehicle. Figure 1C As shown, the camera monitor system including the fixing portion 200 and the upper cover 210 further includes three nut portions inside the panel 10 so as to be fixed to the inner side of the panel 10 .

[0084] Figure 2 A structural diagram of a camera monitor system according to the present invention is shown.

[0085] As shown in the figure, the camera monitor system includes a fixing part 200 and an upper cover 210. Further, the camera assembly 100 and a connecting rod unit 300 are included. The camera assembly 100 is located at the fixing part 200 and is configured to protrude toward the outer side of the panel 10. The connecting rod unit 300 is configured to transmit the rotation force of the driving part 220 to the camera assembly 100.

[0086] The driving unit 220 may include any device capable of providing a rotational force, such as an actuator and a motor. Further, the driving unit 220 includes a driving gear 221 connected to the rotating shaft of the driving unit 220 and a transmission gear 230 connected to the driving gear 221 to apply the rotational force of the driving unit 220 to the connecting rod unit 300.

[0087] The link unit 300 is configured to transmit the driving force of the driving unit 220 to the camera assembly 100. More preferably, it includes a first link 310 and a second link 320, the first link 310 and the transmission gear 230 connected to the driving gear 221 of the driving unit 220 are located on the same axis, and rotate integrally with the rotation of the transmission gear 230, and the second link 320 is adjacent to the first link 310 and connected to the camera assembly 100.

[0088] The first link 310 is located between the transmission gear 230 and the camera assembly 100, and one end of the second link 320 is provided at the fixing portion 200 at a position spaced from the transmission gear 230 and adjacent to the camera assembly 100. Further, the other end of the second link 320 is connected to a position close to the rear end of the camera assembly 100, which is away from the other end of the first link 310 connected to the camera assembly 100.

[0089] That is, the first rotation axis 311 of the first link 310 is configured to be coaxial with the transmission gear 230 to which the driving force of the driving unit 220 is applied, and the second link 320 including the second rotation axis 321 is formed at a position spaced from the transmission gear 230 and adjacent to the camera assembly 100. Further, the first rotation axis 311 is located at a position closer to the front outer side of the vehicle than the second rotation axis 321 in the fixing unit 200.

[0090] As described above, the link unit 300 of the present invention includes a first link 310, which is connected to one end of the camera assembly 100 and transmits a driving force to the camera assembly 100 according to the rotational force of the driving unit 220. In addition, the second link 320 is further included, the second rotation axis 321 of the second link 320 is located at the fixing unit 200, one end of the second link 320 is connected to the camera assembly 100, and is configured to make the camera assembly 100 have a different rotation amount than the rotation amount of the first link 310 rotated by the driving unit 220.

[0091] One end of the first link 310 connected to the camera assembly 100 and both ends of the second link 320 are configured to be able to rotate freely. When the first link 310 rotates with the first rotation axis 311 as a reference, the other end of the first link 310 connected to the shell 110 and the other end of the second link 320 guide the shell 110 to slide and move while rotating.

[0092] More preferably, when the rotation force of the driving unit 220 is applied to the first link 310, the second link 320 can perform the function of guiding the housing 110 so that the rotation center axis 30 of the housing 110 is closer to the front of the vehicle than the rotation axis of the first link 310. Therefore, when the rotation force of the first link 310 is applied to the housing 110, the rotation center axis 30 of the housing 110 is changed to be located at the front end relatively farther from the housing 110 than the first rotation axis 311 as guided by the second link 320, and the rotation amount of the housing 110 is relatively reduced. Therefore, the housing 110 is configured to have a large rotation radius to avoid interference with the opening 20 of the panel 10.

[0093] Furthermore, the fixing portion 200 opposite to the lower surface of the housing 110 includes a supporting portion 201 configured to support the lower surface of the housing 110 .

[0094] In addition, the camera assembly 100 of the present invention includes a housing 110 protruding to the outside of the panel 10, a camera unit 120 located at the rear end of the housing 110, and a decorative portion 130 covering a gap formed between the housing 110 and the panel 10 at the edge of the opening 20 of the panel 10. Further, the decorative portion 130 can perform a function of preventing foreign matter and rainwater from flowing in from the gap.

[0095] The inner end of the housing 110 includes a housing rib 111 arranged to face the inner side of the opening 20 of the panel 10. The housing rib 111 is arranged to extend outward along the inner end edge of the housing 110, and to contact the inner side of the panel 10 or the decorative portion 130 when the housing 110 is unfolded. In addition, the housing rib 111 may include a cover (not shown) located at a position facing the inner side of the panel 10.

[0096] Further, the case rib 111 provides an effect of preventing wind noise from being generated due to a gap between the panel 10 and the case 110 when the case 110 is unfolded.

[0097] More preferably, the camera unit 120 of the present invention includes at least one of a surround view monitoring camera, a digital rearview mirror camera, and an infrared camera. The side rear and side lower end images of the vehicle captured by the camera unit 120 are displayed by at least one display unit located in the vehicle and provided to the user. In addition, the decorative portion 130 is configured to cover the opening portion 20 of the panel 10 and surround the edge of the housing 110.

[0098] Therefore, when the camera unit 120 integrally protrudes to the outside of the panel 10 with the housing 110 , it is possible to provide surround view monitoring to the inside of the vehicle while providing a side rear view of the vehicle to the inside of the vehicle.

[0099] The driving part 220 is connected to the panel 10 or the fixing part 200, and is configured so that the rotation axis of the driving part 220 protrudes toward the upper end of the fixing part 200 and rotates integrally with the driving gear 221. Further, a transmission gear 230 is coaxially located with the first rotation axis 311 of the first connecting rod 310, and the transmission gear 230 is connected to the driving gear 221. Therefore, the rotation force of the driving gear 221 is transmitted to the transmission gear 230, and the first connecting rod 310 rotates with the first rotation axis 311 as a reference.

[0100] The second link 320 is connected to a position adjacent to the rear end of the housing 110, and includes a second rotation axis 321 at one end of the second link 320 that is closer to the housing 110 than the first rotation axis 311. Further, in response to the rotation of the first link 310, the rotation center axis 30 of the housing 110 can be changed, and when the camera assembly 100 protrudes to the outside of the panel 10, the movement of the housing 110 in the width direction is guided without interfering with the opening 20 of the panel 10. More preferably, in the case where the housing 110 protrudes to the outside of the panel 10, the housing 110 rotates with the rotation center axis 30 located more forward than the first rotation axis 311 as a reference, and the housing 110 that actually protrudes has a relatively small rotation amount compared to the rotation amount rotated with the first rotation axis 311 as a reference.

[0101] Further, in the case where the housing 110 protrudes to the outside of the panel 10, the protrusion amount of one end of the housing 110 adjacent to the driving unit 220 has a relatively smaller protrusion amount than the protrusion amount of the other end of the housing 110. That is, the rotation center axis 30 of the housing 110 is configured to rotate with respect to the imaginary rotation center axis 30 relatively closer to the front of the vehicle than the first rotation axis 311. Therefore, the rear end of the housing 110 located at a position away from the rotation center axis 30 has a relatively larger protrusion amount than the front end of the housing 110.

[0102] In addition, the control unit 400 can control the camera monitor system to protrude outside the panel 10 in consideration of the user's request or the driving environment. That is, the control unit 400 can control the on and off of the driving force of the driving unit 220 and control the operation of the camera unit 120 of the protruding camera monitor system.

[0103] Furthermore, the control unit 400 can measure the stall current of the driving unit 220. Therefore, when the first link 310 contacts the stopper 240 located on the rotation track of the first link 310 and is restricted from further rotation, that is, when it is determined that the stall current of the driving unit 220 is greater than a predetermined value, control is performed to disconnect the operation of the driving unit 220.

[0104] As such, the stopper 240 is located at the rotation radius when the first link 310 is driven, thereby limiting the rotation of the first link 310 so that the camera assembly 100 cannot exceed the maximum protrusion amount. Further, the control unit 400 is configured to measure the stall current of the driving unit 220 when the first link 310 contacts the stopper 240 and does not rotate, and convert the driving unit 220 to the disconnected state, thereby preventing overcurrent from being applied to the driving unit 220.

[0105] Figure 3A and Figure 3BThe state where the camera monitor system is accommodated inside the opening 20 of the panel 10 is shown.

[0106] The camera monitor system is configured such that, when stored inside the panel 10, the outer side surface of the panel 10 forms the same plane as the outer side surface of the housing 110 located at the opening 20 of the panel 10. Furthermore, the driving unit 220 maintains the disconnected state, and the link unit 300 is configured to be provided at the fixing unit 200 at a fixed position.

[0107] Afterwards, if FIG. 4A to FIG. 4B As shown, when the control unit 400 receives a request from the user, or detects that the speed of the vehicle exceeds a predetermined speed or the vehicle is switched to a start state based on the driving environment of the vehicle, the drive unit 220 is switched to an on state, so that the camera assembly 100 protrudes to the outside of the panel 10.

[0108] At this time, the control unit 400 supplies power to the driving unit 220 and switches the camera unit 120 to the on state. Further, in response to the rotation of the driving unit 220, the transmission gear 230 connected to the driving gear 221 is rotated, and the first link 310 is rotated with the first rotation shaft 311 coaxially formed as one body with the transmission gear 230 as a reference. The first link 310 including the first rotation shaft 311 rotates according to the driving of the driving unit 220, and the other end of the first link 310 connected to the camera assembly 100 rotates toward the outside of the vehicle, so that the housing 110 protrudes toward the outside of the opening 20 of the panel 10.

[0109] Further, the second link 320 is a guide rod configured to increase the rotation radius of the housing 110 when the housing 110 rotates according to the rotation force of the first link 310. That is, the housing 110 does not rotate around the first rotation axis 311 to which the rotation force of the driving unit 220 is applied, but the rotation center axis 30 of the housing 110 is formed at a predetermined position closer to the front of the vehicle than the first rotation axis 311 by the first rotation axis 311 and the second rotation axis 321. More preferably, when the driving force of the driving unit 220 is applied to the housing 110, the rotation center axis 30 can be changed to a position closer to the front of the vehicle than the first rotation axis 311.

[0110] Therefore, when the housing 110 protrudes to the outside of the opening 20 of the panel 10, the housing 110 rotates with the rotation center axis 30 formed by the fixed axis of the first link 310 and the second link 320 as the reference. That is, the housing 110 that rotates with the rotation center axis 30 formed by the fixed axis of the first link 310 and the second link as the reference is configured to have a relatively larger rotation radius than the rotation radius of the housing 110 that rotates with the first rotation axis 311 as the reference, so that the housing 110 can rotate and move without interfering with the front and rear ends of the opening 20.

[0111] Figure 5A The protrusion amount of the protruding camera assembly 100 according to an embodiment of the present invention is shown.

[0112] As shown in the figure, when the camera assembly 100 protrudes to the outside of the opening 20, the rear end of the housing 110 has a relatively larger protrusion amount than the front end. That is, the housing 110 rotates with the rotation center axis 30 formed by the first rotation axis 311 and the second rotation axis 321 as a reference, so the rear end of the housing 110 located relatively far from the rotation center axis 30 has a larger protrusion amount than the front end. Further, the camera unit 120 located at the rear end of the housing 110 is configured to protrude to the side of the vehicle and is configured to be able to capture images of the side rear and lower end areas of the vehicle.

[0113] Furthermore, if Figure 5B and Figure 5C As shown, the protruding camera assembly 100 rotates with the rotation center axis 30 as a reference, and the rotation center axis 30 is formed by the first link 310 and the second link 320 rotating with the first rotation axis 311 and the second rotation axis 321 located at the fixed part 200 as fixed axes, and the rotation center axis 30 of the housing 110 is configured to be located at a position relatively closer to the front of the vehicle than the first rotation axis 311 and the second rotation axis 321. Therefore, the housing 110 has a relatively smaller rotation amount than the rotation radius rotating with the driving part 220 as a reference, and can move toward the outside of the opening part 20 without interference along the lateral direction.

[0114] Therefore, if Figure 5C As shown, the front end of the housing 110 in the longitudinal direction has a rotation amount that does not interfere with the opening 20 of the panel 10, and the rear end of the housing 110 has a relatively larger protrusion amount than the front end.
