Description

Car rearview mirror

[0001] The present invention relates to a rearview mirror for a vehicle, and more specifically, to a rearview mirror for a vehicle that provides an external image of the vehicle or an image necessary for driving.

[0002] Rearview mirrors installed in automobiles are generally used by drivers to secure a view of the rear of the vehicle, and recently, they have evolved into digital display type rearview mirrors that provide real-time information on external conditions or driving conditions.

[0003] These digital rearview mirrors contribute to improving driving safety and convenience by displaying images acquired from a rear camera or visually providing the driver with information such as navigation and rear detection sensors.

[0004] However, there was a problem in that visibility was significantly reduced because the display conditions of the visual information display remained unchanged even when external environmental conditions, such as weather or vehicle location, changed during operation.

[0005] Furthermore, when the visibility of the display is reduced, users are unable to respond immediately, significantly lowering driving convenience; additionally, the problem escalated into a decline in stability as it interfered with the acquisition of external images and necessary information.

[0006] One embodiment of the present invention is devised to solve the above-mentioned problems and aims to provide a vehicle rearview mirror having improved convenience and safety by optimizing the image provided to the user.

[0007] A vehicle rearview mirror according to one embodiment of the present invention comprises: a housing providing an installation space open to one side; a main board positioned opposite the open portion of the installation space to generate an image signal; a display unit installed in the open portion of the installation space to display the image signal; and an operating unit formed on the outside of the housing to provide an adjustment signal to the main board by operation; wherein the operating unit is formed with an installation member providing an operating axis, a rotary operating body assembled on the outside of the housing to be rotatable on the operating axis, an operating circuit board connected to the operating axis to generate the adjustment signal corresponding to the rotation angle of the rotary operating body, and a connecting circuit electrically connecting the operating circuit board and the main board, thereby varying the image signal through the adjustment signal.

[0008] The above-described control circuit board is formed with a disk connected to the control axis and having a slot portion formed on one side, a sensor portion that detects the slot and measures the rotation angle of the disk, and a control board that generates the adjustment signal through the measurement value of the sensor portion, thereby being able to generate the adjustment signal corresponding to the number of detected slots.

[0009] The sensor unit is formed with a plurality of different sensors having a phase difference, and can generate a first adjustment signal corresponding to the rotation direction of the disk through the sensor that detects the slot first among the plurality of sensors, and can generate a second adjustment signal corresponding to the degree of rotation of the disk in correspondence with the cumulative number of detected slots.

[0010] The above-described rotary operating body is formed with a signal pin that penetrates the inner side of the operating shaft and is detachably connected to the operating circuit board and generates a mode signal, an operating member that is rotatably assembled to the end of the signal pin, and a return spring that is formed on the outer side of the signal pin and is installed to be expandable between the operating shaft and the operating member, thereby moving the operating member in the axial direction to generate the mode signal, and allowing the operating member to return to its original position by the return spring.

[0011] As the above signal pin comes into contact with the above control circuit board, it can change the elements of the image signal that are varied by the adjustment signal.

[0012] The above connection circuit may be formed as a flexible board connected to a first connection unit formed on one side of the main board and connected to the main circuit on the inside, and a second connection unit formed on one side of the control circuit board and connected to the control circuit on the inside.

[0013] The above housing has a recessed portion that is recessed from the outside into the installation space to provide a space for assembling the rotary operating body, and an assembly hole formed through the recessed portion, so that the installation member is positioned on the outside of the housing and can transmit the adjustment signal to the main board through the operation of the operating member.

[0014] The above housing may further have an assembly hook formed therein that protrudes from the inner side of the recessed portion and secures the operating circuit board, thereby guiding the position of the connection circuit.

[0015] As examined above, various effects including the following can be expected according to the means for solving the problem of the present invention. However, the present invention is not required to exhibit all of the following effects to be valid.

[0016] The vehicle rearview mirror of the present invention forms an operating part on the outer side of the housing, thereby improving user convenience and safety by allowing the display part, which displays external images required during driving, to be easily operated according to the driving environment.

[0017] In addition, by separating the control unit from the outside of the housing, that is, from the display unit where the external image is displayed, it provides the effect of improving image visibility and simultaneously enhancing the appearance quality.

[0018] In addition, by enabling the manipulation of various video elements through a single control unit, it allows for more convenient operation, thereby maximizing the effect of enhancing user convenience.

[0032] Referring to FIGS. 1 to 7, a vehicle rearview mirror (10) of an embodiment of the present invention comprises a housing (100) providing an installation space (130) open to one side, a main board (200) positioned opposite the open portion of the installation space (130) to generate an image signal, a display unit (300) installed in the open portion of the installation space (130) to display the image signal, and an operating unit (400) formed on the outside of the housing (100) to provide an adjustment signal to the main board (200) by operation, wherein the operating unit (400) comprises an installation member (410) providing an operating axis (412), a rotational operating body (420) assembled to be rotatable on the operating axis (412) on the outside of the housing (100), and a unit connected to the operating axis (412) to generate the adjustment signal corresponding to the rotation angle of the rotational operating body (420). It is characterized by being formed with an operating circuit board (430) and a connecting circuit (440) that electrically connects the operating circuit board (430) and the main board (200), thereby varying the video signal through the adjustment signal.

[0033] The vehicle rearview mirror (10) of the present invention is a digital vehicle rearview mirror (10) that provides real-time visual information regarding external conditions of the vehicle or necessary driving information during vehicle operation.

[0034] To this end, the vehicle rearview mirror (10) of the present invention is formed with a housing (100) that provides an exterior and an installation space (130), a main board (200) installed in the housing (100) that generates a video signal, a display unit (300) that displays the video signal, and an operating unit (400) that provides an adjustment signal for varying the video signal.

[0035] Here, the control unit (400) is formed on the outside of the housing (100) so that the user can directly operate it, and provides an adjustment signal for adjusting various elements constituting the image signal through axial operation and circumferential operation.

[0036] Specifically, the housing (100) is formed with a housing body (110) that forms the exterior of a vehicle rearview mirror (10), and an installation space (130) on the inside of the housing body (110) where other components are installed.

[0037] At this time, one side of the housing body (110) is opened, and an opening (120) is formed on one side of the installation space (130).

[0038] Additionally, an assembly part (140) is further formed on one side of the housing body (110) to which an operating part (400) is assembled, so that an image signal can be adjusted through the operating part (400) from the outside of the housing (100).

[0039] To this end, the assembly part (140) is formed by a recessed section (141) formed by being recessed into the installation space (130) from the outside of the housing body (110), an assembly hole (142) formed by penetrating the recessed section (141), and an assembly hook (143) formed extending from one side of the recessed section (141).

[0040] Specifically, the recessed portion (141) is recessed from the outside of the housing (100) so as to protrude into the installation space (130), thereby providing a space where the installation member (410) is assembled. At this time, an assembly hole (142) is formed through the recessed portion (141) to allow the installation member (410) to be placed.

[0041] In addition, the recessed portion (141) and the installation member (410) are assembled so as to be spaced apart by a predetermined distance in the axial direction, thereby providing a structure in which the operating portion (400) can move a predetermined distance in the axial direction.

[0042] And on one side of the recessed section (141), that is, the part protruding into the installation space (130), an assembly hook (143) is further formed that extends in the axial direction to fix the operating circuit board (430).

[0043] Accordingly, the position where the control circuit board (430) and the main board (200) are connected is fixed, improving the workability of the operator and preventing damage to the connection circuit (440).

[0044] In summary, the vehicle rearview mirror (10) of the present invention provides a space for installing other components, thereby providing the driver with external images and information necessary for driving. Additionally, the control unit (400) is formed on the outside of the housing (100), and the state of the images and information can be easily operated through a structure connected to the installation space (130).

[0045] The main board (200) is configured to be positioned opposite the opening (120) of the installation space (130) to generate video signals, and is connected to various electronic components such as cameras to select and provide external video and information necessary for the driver.

[0046] Accordingly, the main board (200) is formed with a main board (210) having a main circuit that receives necessary electrical signals from various electrical components, and a first connection unit (220) formed on one side of the main board (210) to which a connection circuit (440) is connected.

[0047] Here, the main circuit is electrically connected to an electrical component that provides information required during operation, such as a camera, or information required by the user, and forms a video signal so that it can be displayed on the display unit (300).

[0048] And the first connection unit (220) is formed on one side of the main board (210) and has a structure in which one end of the connection circuit (440) is connected. At this time, a part of the main circuit is exposed on the inside of the first connection unit (220) and is electrically connected to the connection circuit (440).

[0049] In other words, the main board (200) converts the video of the external environment, necessary driving information, and user request information into an electrical signal, which is a video signal, and transmits it to the display unit (300).

[0050] In addition, the video signal is varied through the adjustment signal transmitted through the connection circuit (440) to adjust the elements of the video displayed on the display unit (300).

[0051] In this context, image elements refer to various adjustable factors, such as image brightness, color tone, the field of view of external images provided by the camera, and the type of image, that enable the driver and user to easily recognize the provided information.

[0052] Here, the type of image refers to the image provided by a camera selected by the user from among various types of cameras (RGB cameras, IR cameras, thermal sensor cameras, etc.) in response to the external environment and the vehicle's installation location.

[0053] In addition, among the video elements, it also includes information and options that can be optimized for each individual user, such as information selected by the user or the location where information is displayed.

[0054] In other words, an adjustment signal is generated through the user's control unit (400), and the video signal is varied according to the adjustment signal generated at this time, so that various elements of the video can be adjusted or information displayed can be selected.

[0055] The display unit (300) is installed in the opening (120) of the installation space (130) and is configured to display images and information corresponding to video signals.

[0056] To this end, the display unit (300) is formed with an image display unit (310) that receives an image signal and displays images and information, and a protection unit (320) that is formed on the outside of the image display unit (310) and protects from the outside.

[0057] At this time, the display unit (300) is formed to close the entire area of ​​the opening (120) and functions to protect the main board (200) and the control circuit board (430) formed as the installation space (130).

[0058] The control unit (400) is assembled to the outside of the housing (100) and is electrically connected to the main board (200) in the installation space (130) to provide an adjustment signal corresponding to the user's operation and to vary the video signal. Accordingly, the elements of the video displayed on the display unit (300) are adjusted.

[0059] Specifically, the control unit (400) is formed with an installation member (410) formed on the outside of the housing body (110) so that the user can easily operate it, an operation circuit board (430) that generates an adjustment signal by operating the installation member (410), and a connection circuit (440) that connects the operation circuit board (430) and the main board (210).

[0060] Looking at this in more detail, the installation member (410) is formed into the inner side of the recess through the assembly hole (142) to provide a structure in which the rotational operation body (420) is assembled.

[0061] To this end, the installation member (410) is formed with an installation body (411) formed on one side of the operating circuit board (430) and an operating shaft (412) that extends axially from the installation body (411) and is formed on the inner side of the recessed portion.

[0062] At this time, a disk (432) is received inside the installation body (411). Additionally, the disk (432) is connected to the operating shaft (412) through a through hole (4321) to link the operating member (422) and the disk (432).

[0063] That is, when the operating member (422) is rotated, the disk (432) is also rotated by the operating shaft (412). Accordingly, the degree of rotation of the disk (432) corresponds to the degree of operation of the operating member (422), and the sensor unit recognizes this and converts it into an electrical adjustment signal.

[0064] In other words, the installation member (410) provides a structure in which the rotary operating body (420) is assembled to the outside of the housing of the assembly hole (142). Additionally, the part where the circuit board (430) and the signal pin (421) are electrically connected is accommodated to the inside to ensure electrical connection stability.

[0065] Accordingly, the control unit (400) connects the rotary control body (420) and the control circuit board (430) through the installation member (410) to generate an adjustment signal corresponding to the operation of the rotary control body (420).

[0066] The rotary operating body (420) is formed of a signal pin (421) that is detachably attached to the operating circuit board (430) and an operating member (422) that is rotatably assembled to the end of the signal pin (421).

[0067] Here, the signal pin (421) is formed in a structure that can be directly connected to the control circuit board (430) by sequentially passing through the control axis (412) and the through hole (4321).

[0068] To examine this in more detail, the signal pin (421) remains separated from the initial control circuit board (430), but when the operator moves the control member (422) in the axial direction, the signal pin (421) also moves upward in the axial direction and comes into contact with the control circuit board (430), thereby generating a mode signal.

[0069] Specifically, the mode signal is a signal that changes an element of an image adjusted by an adjustment signal through the operation of the signal pin (421) being electrically connected to or electrically disconnected from the control circuit board (430).

[0070] To examine this in more detail, the signal pin (421) is detached from the operating circuit board (430) by the axial movement of the operating member (422) and the return of the operating member (422) through the elastic restoring force of the return spring (423), and generates a mode signal.

[0071] At this time, the signal pin (421) is designed to be variable whenever it contacts the control circuit board (430) to generate a mode signal, and the image element adjusted by the adjustment signal is varied.

[0072] For greater convenience, the mode signal is transmitted to the main board (210) through the connection circuit (440), and this is then transmitted to the display unit (300) through the video signal so that the type of the element being adjusted or the degree of adjustment can be displayed.

[0073] Accordingly, users can visually check the video elements currently being adjusted and the degree of adjustment, enabling more convenient adjustments.

[0074] The operating member (422) is formed with an operating body (4221) that is coupled to the inside of the recessed portion and protrudes to the outside of the housing (100), and an operating lip (4222) that extends axially from the inside of the operating body (4221) and is connected to the signal pin (421).

[0075] At this time, it is desirable that the operating body (4221) protrudes outward from the housing (100) so that the user can grip it more easily. More preferably, the operating body (4221) has a circular cross-section so that the user can easily rotate it in a circumferential direction.

[0076] And, the control lip (4222) extends axially from the center of the control body (4221) and is assembled to the end of the signal pin (421).

[0077] Accordingly, when the operating body (4221) is pressed in the axial direction from the outside of the user's housing (100), the signal pin (421) also moves upward in the axial direction and can be electrically connected to the operating circuit board (430).

[0078] Additionally, the control body (4221) is assembled to be rotatable in a circumferential direction around the signal pin (421). Accordingly, the user can rotate the control body (4221) in a circumferential direction, and at this time, the control circuit board (430) generates an adjustment signal corresponding to the rotation direction and degree of rotation of the control body (4221).

[0079] In other words, the rotary operating body (420) is installed on the outside of the recessed end (141) and connected to the signal pin (421) on the inside, having a structure that allows rotation in the circumferential direction. At this time, the operating member (422) is installed at a predetermined distance in the axial direction from the recessed end (141) and assembled so as to be movable in the axial direction.

[0080] Accordingly, the rotary operating body (420) generates a mode signal by being involved in the electrical connection state between the signal pin (421) and the operating circuit board (430) through axial movement, and generates an adjustment signal through circumferential rotation.

[0081] To this end, a disk (432) linked to the rotation of the operating body (4221) is connected to one side of the signal pin (421), and it is preferable that a return spring (423) is further formed between the operating shaft (412) and the operating rib (4222).

[0082] Here, the return spring (423) is compressed as the operating member (422) is pressed upward in the axial direction so that the signal pin (421) and the operating circuit board (430) are electrically connected, and when the pressing force is removed, it generates an elastic restoring force to return the operating member (422) to its original position.

[0083] Accordingly, the user can generate a mode signal by repeatedly pressing the control member (422) without any separate operation, and thereby change the elements of the image that are continuously adjusted by the adjustment signal.

[0084] In addition, when the return spring (423) is compressed, the operating body (4221) contacts the end protruding inwardly from the recessed end (141), thereby limiting the axial movement distance. Therefore, the user can immediately recognize that a mode signal has been generated, so the operating part (400) of the present invention provides improved convenience.

[0085] The control circuit board (430) is formed inside the installation space (130) to detect the rotation direction and degree of rotation of the rotation control body (420) and generate an adjustment signal, and is electrically connected to the signal pin (421) and generates a mode signal.

[0086] To this end, the control circuit board (430) is formed with a control board (431) having a control circuit formed therein that generates a mode signal through an electrical connection with a signal pin (421) and simultaneously detects the operation of the control body (4221) to generate an adjustment signal, a disk (432) disposed on one side of the control board (431) and rotates together with the rotational control body (420), and a sensor part (not shown) that detects the rotation of the disk (432).

[0087] At this time, on one side of the operating board (431), a second connection unit (4311) connected to the connection circuit (440) and an assembly hole (4312) in which the assembly hook (143) is fixed are formed.

[0088] Here, a part of the operating circuit is exposed on the inner side of the second connection unit (4311) and is electrically connected to the connection circuit (440). Additionally, the disk (432) is connected to the signal pin (421) and rotates in conjunction with the rotation of the operating member (422).

[0089] At this time, a slot is formed in the disk (432), and the sensor unit transmits an electrical signal corresponding to the number of slots detected according to the degree of rotation of the disk (432) to the control board (431), thereby generating a corresponding adjustment signal.

[0090] Specifically, multiple slots are formed on the disk (432) at regular intervals in the circumferential direction. More preferably, the sensor part is formed with multiple sensors having a phase difference, and the rotational direction of the operating member (422) is detected through the position of the sensor where the first slot is detected.

[0091] Accordingly, the control board (431) generates a first adjustment signal that determines the rotation direction of the disk (432), that is, the operation direction of the control member (422), through a sensor that detects the slot first. It also generates a second adjustment signal that determines the cumulative number of detected slots, that is, the degree of operation of the control member (422).

[0092] Additionally, a through hole (4321) is further formed in the disk (432) that is open in the axial direction and through which the signal pin (421) passes. That is, the disk (432) has a structure that is fixed in the circumferential direction of the signal pin (421) and interlocks with the rotational operation body (420), while simultaneously providing a structure in which the signal pin (421) can directly contact the operation board (431).

[0093] In summary, the control circuit board (430) generates first and second adjustment signals and mode signals through the axial and circumferential movement of the control body (4221) to vary the image signal. That is, the image and information signals displayed on the display unit (300) are changed solely by the operation of the rotary control body (420).

[0094] The connection circuit (440) is formed internally, and one end is connected to the main circuit through the first connection unit (220), while the other end is connected to the operation circuit through the second connection unit (4311) to form a single signal transmission circuit.

[0095] Specifically, the connection circuit (440) is configured to transmit the first and second adjustment signals and mode signals generated in the control circuit to the main circuit, and it is preferable that it be formed as a flexible circuit to ensure ease of assembly.

[0096] At this time, the operating board (431) is fixed by an assembly hook (143) formed on one side of a recess protruding into the installation space (130) penetrating the assembly hole (4312). Accordingly, the second connection unit (4311) connected to the connection circuit (440) is also fixed at a specific position, allowing the main circuit and the operating circuit to be connected more stably.

[0097] Accordingly, multiple assembly holes (4312) are formed along the edge of the operating board (431) to provide more stable fixing force and ultimately provide a more stable electrical connection.

[0098] To summarize once again, the vehicle rearview mirror (10) of the present invention is equipped with an operating unit (400) composed of a rotational operating body (420) assembled to the outside of a housing (100) and an operating circuit board (430) formed to the inside of the housing (100) and generating an adjustment signal corresponding to the operation of the rotational operating body (420), thereby allowing the driver and passenger to easily operate the vehicle rearview mirror (10).

[0099] At this time, the rotational control body (420) allows the user to change the elements of the image to be adjusted through a structure that can move in the axial direction, and allows the user to select the degree of adjustment through a structure that rotates in the circumferential direction.

[0100] Therefore, the vehicle rearview mirror (10) of the present invention can be easily adjusted when image visibility is reduced during driving, thereby significantly improving user convenience. In addition, it provides the effect of improving safety by reliably conveying necessary information to the driver during driving.

[0101] Although preferred embodiments of the present invention have been described illustratively above, the scope of the present invention is not limited to such specific embodiments, and any modifications that are appropriately possible within the scope described in the claims fall within the scope of protection of the present invention.
