Description

Technology Field

[0001] The present invention relates to a side mirror device for an automobile having a collision prevention function. More specifically, the present invention relates to a side mirror device for an automobile having a collision prevention function that can prevent a collision by folding the side mirror when an object is detected before the driver perceives the possibility of a collision while driving. Background Technology

[0003] Generally, vehicle side mirrors are installed on both sides of the vehicle body, facing forward of the driver and passenger seats, respectively, allowing the driver to secure visibility to the sides and rear without having to turn their head completely, thereby enabling them to assess the situation of following vehicles.

[0004] Through this, the driver can safely perform left turns, right turns, or lane changes while driving using the side mirrors.

[0005] Since these side mirrors protrude outward from the vehicle body, there is a problem in that there is a high possibility of collision with other objects while the vehicle is in motion (including while parked).

[0006] In this regard, as prior art related to the protection of the exterior of a side mirror, Korean Published Patent Application No. 10-2014-0124573 (Date of publication: October 27, 2014) was disclosed.

[0007] The above prior art relates to a side mirror of an automobile and discloses a technology comprising a movable body, a main body, and a mirror connected so as to be folded or unfolded, which completely stores the mirror inside the vehicle body so as not to protrude outside the vehicle body, thereby preventing the side mirror from being damaged by colliding with other vehicles, pedestrians, and surrounding obstacles.

[0008] However, in the case of the prior art, since the side mirror is retracted by the driver's operation based on the premise of driver awareness, there are limitations in preventing damage to the side mirror in situations where the driver cannot recognize surrounding pedestrians or objects while the vehicle is in motion.

[0009] In addition, there is a problem that reduces driver convenience because the driver must always operate a button to change the position of the side mirror.

[0010] Furthermore, in the case of automatic side mirrors, the high cost of parts causes financial losses for drivers and economic losses due to vehicle repairs. The problem to be solved

[0012] The problem that the present invention aims to solve is to provide a side mirror device for an automobile having a collision prevention function that can prevent a collision by folding the side mirror when an object is detected before the driver perceives the possibility of a collision while driving. means of solving the problem

[0024] The present invention has the advantage of preventing collisions by folding the side mirrors when an object is detected before the driver perceives the possibility of a collision while driving. Brief explanation of the drawing

[0026] FIG. 1 shows a collision prevention function according to an embodiment of the present invention. Block diagram showing a side mirror device for an automobile. FIGS. 2(a) and 2(b) are drawings showing a side mirror applied to the present invention. Specific details for implementing the invention

[0027] Hereinafter, the side mirror device for an automobile having a collision prevention function according to the present invention will be described in detail with reference to the attached drawings. However, a person skilled in the art would understand that the present invention can be modified or altered in various ways within the scope of the embodiments described below. Such modifications or alterations are also to be considered to be included within the scope of the present invention.

[0029] As illustrated in FIGS. 1 and 2, a side mirror device for an automobile having a collision prevention function according to an embodiment of the present invention includes a vehicle speed sensor (100), an ultrasonic sensor (200), a folding member (300), and a control member (600).

[0030] The above vehicle speed sensor (100) is equipped in a vehicle and detects the speed of the vehicle. This vehicle speed sensor (100) can be configured as a reed switch type or a photoelectric sensor to detect the driving speed of the vehicle.

[0031] The above ultrasonic sensor (200) is installed on a side mirror (10) that is rotatably provided on a vehicle to detect an object. This ultrasonic sensor (200) is installed on the back of the side mirror (10). And with the ultrasonic sensor (200) installed on the back of the side mirror (10), it can easily detect an object located in front of the vehicle.

[0032] More specifically, these ultrasonic sensors (200) are configured in multiple units and are installed on the left and right side mirrors (10), respectively. That is, the ultrasonic sensor (200) installed on the left side mirror (10) of the vehicle detects an object located in front of the vehicle from the left side, and the ultrasonic sensor (200) installed on the right side mirror (10) of the vehicle detects an object located in front of the vehicle from the right side.

[0033] Therefore, the ultrasonic sensor (200) can detect other vehicles, pedestrians, or objects such as tree branches located in front of the vehicle on one side (left or right).

[0035] The above folding member (300) is intended to fold or unfold the side mirror (10) and may be composed of a motor that rotates a motor shaft connected to the side mirror (10) in the forward or reverse direction. When such a motor rotates the motor shaft in the forward direction, the side mirror (10) rotates together with the motor shaft and protrudes outward from the vehicle, and when the motor rotates the motor shaft in the reverse direction, the side mirror (10) rotates in the reverse direction together with the motor shaft and approaches the outer side of the vehicle. Therefore, when the side mirror (10) approaches the outer side of the vehicle, the side mirror (10) does not collide with an external object.

[0036] And the folding member (300) is composed of multiple parts to fold or unfold the left side mirror (10) and the right side mirror (10), respectively.

[0038] The above control member (600) controls the folding member (300) so that the side mirror (10) is folded when the ultrasonic sensor (200) detects an object while the vehicle speed sensor (100) detects the speed. The control member (600) includes a speed checking unit (610) that checks the speed detected by the vehicle speed sensor (100), an object checking unit (620) that checks when the ultrasonic sensor (200) detects an object, a folding operation unit (630) that operates the folding member (300) to fold or unfold the side mirror (10), a speed judgment unit (640) that determines whether the speed confirmed by the speed checking unit (610) matches a preset reference speed, and a folding control unit (650) that controls the folding operation unit (630) to fold the side mirror (10) when the speed confirmed by the speed judgment unit (640) determines that it matches the reference speed and the object checking unit (620) confirms an object.

[0039] Here, the standard speed can be set to 10 to 40 km / h. It is preferable to set it to 30 km / h.

[0040] Therefore, when the ultrasonic sensor (200) detects an object while the car is traveling at a speed of 30 km / h, the folding control unit (650) controls the folding operation unit (630) to cause the side mirror (10) to be folded.

[0041] In addition, the folding control unit (650) controls the folding operation unit (630) to unfold the side mirror (10) if the object confirmation unit (620) does not confirm object detection.

[0042] In addition, the folding control unit (650) controls the left or right folding member (300) so that the left or right side mirror (10) is folded when the ultrasonic sensor (200) installed on the left or right side mirror (10) detects an object.

[0043] In this way, as the vehicle is driving, the ultrasonic sensor (200) detects an object located in front of the side mirror (10), so the side mirror (10) is automatically folded so that it does not collide with the object. That is, it is possible to prevent the side mirror (10) from colliding with an object and being damaged.

[0044] And the side mirror (10) can be unfolded after preventing collision with an object after it has been automatically folded. That is, the driver can perform safe driving by checking the automatically unfolded side mirror (10).

[0045] As such, according to the present invention, since the side mirror can be folded to prevent a collision when an object is detected before the driver perceives the possibility of a collision while driving, it can be said to be a very useful invention.

[0046] Those skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive, and the scope of the present invention is defined by the claims set forth below rather than by the detailed description, and all modifications or variations derived from the meaning and scope of the claims and equivalents thereof should be interpreted as being included within the scope of the present invention.
