Description

Safety Back Mirror for Vehicle

The present invention relates to a safety mirror for the rear of an automobile, and more particularly, to compactly configure parts such as elastic members fixed to the cover side for the complete spreading of the mirror, saving overall space and providing a means for converting the drive motor forward and reverse rotation. The present invention relates to a safety mirror for the rear of a car, which has been improved from an electronic device to an electronic control device, thereby ensuring safe operation due to frequent reverse conversion of the drive motor, and greatly reducing the overall volume to achieve compactness of the device.

It is a device that informs the driver of the situation of the front, rear, left and right corners of a car that is generally blind from the driver's seat. Ultrasonic sensors are installed at each corner of the front bumper and the rear bumper to detect obstacles near the corners of the car. A so-called 'warning warning system' is installed in the vehicle that informs the approximate distance of obstacles with a buzzer or warning lamp.

In particular, when the vehicle is parked, the vehicle is parked by carefully driving forward or rearward while visually observing the situation behind the vehicle using a room mirror inside the vehicle or a rearview mirror attached to the front of the vehicle.

This method is a normal parking method, which relies entirely on the driver's sense of driving. Therefore, in the case of an inexperienced driver, his vehicle is separated from the rear obstacles, for example, a wall or another vehicle, to some extent. There was a case in which the contact accident was insensitive to the presence of contact.

In the case of an inexperienced driver, there is a demand for a device that allows a user to know a certain parking distance as the distance sensation becomes dull and damages the vehicle during parking rather than driving.

Conventionally, as an alarm device to assist parking, a device is provided to warn the driver when there is an obstacle at a distance of 1 meter, 50 centimeters, 30 centimeters, etc. using laser or ultrasonic waves.

In such a close-warning system, an ultrasonic sensor using a piezoelectric piezoelectric element, which is mechanically deformed when an electric field is applied, is mainly used, which measures the time until the sound wave emitted from the transmitter hits an obstacle and returns. The device measures the distance to obstacles.

In addition, a back monitor camera device in which a monitor camera is installed at the rear of the vehicle so as to reverse the vehicle while checking the rear situation with the eyes when the vehicle is reversed is also utilized.

In this case, a 1 / 2-inch color monitor using a high-sensitivity CCD imager is embedded in the rear spoiler of a car. Other details will be omitted below because they are far from the nature of the present invention.

A spoiler is a stabilizer of the shape of an aircraft wing which is usually installed at the front lower side or rear upper side of a racing vehicle. The spoiler also means an article which prevents the injury of the vehicle when driving at high speed. Also known as an aero stabilizer.

Conventional proximity warning systems use ultrasound or video cameras, so the system itself requires precision, while automobiles often run under poor road conditions. It was too expensive for the users to turn away, so there was no real application.

In view of this point, it is the applicant of the present applicant (utility model registration application 20-1997-3055; automobile rearview mirror) which provided the rear safety mirror apparatus which consisted of pure mechanical equipment instead of electronic equipment.

It is equipped with a mirror with a link at the top of the trunk or in the center of the spoiler, and is driven by the drive motor to unfold or fold it.

Therefore, this design allows the driver to visually check the rear of the vehicle when the vehicle is reversed when the vehicle is reversed, and when the vehicle is reversed, the mirror is folded again and concealed into the spoiler. It is not supposed to give.

However, the conventional automotive reverse mirror has the following problems.

1. When the mirror is unfolded by the drive motor, the elastic member is elastically installed between the fixing parts corresponding to the entire width of the cover side to ensure the safe spread of the mirror.

This elastic member acts to push the mirror to the outer side at the end of the operation in order to fully unfold the mirror.

By the way, this elastic member, that is, the fixing member and the elastic member (spring) are unnecessarily installed on the cover side unnecessarily to increase the manufacturing cost, in particular the elastic member is installed in the rear portion of the mirror has a lot of difficulties in manufacturing and There is also difficulty in repairing or replacing the mirror. In addition, the fixing projections on both sides of the cover for supporting the fixing rod are too large compared to other components, which also causes a waste of materials and cannot be compactly constructed.

2. The safety mirror for the rear of the car is operated by the operation of the reverse gear of the car. That is, when the driver inserts the reverse gear, the on / off switch installed on the reverse gear operates to apply power to the drive motor, and the drive motor rotates forward to spread the mirror. When the vehicle is moved to the parking or neutral position, the on / off switch operates in the off position to send a signal to the driving motor, and the driving motor rotates backward to close the mirror.

At this time, conventionally, the device for limiting the forward / reverse rotation of the drive motor to a predetermined time (or rotational speed) is made by pure mechanical configuration, that is, the action of two limit switches and a coil spring elastically installed on the first shaft. Due to the frequent repetitive use, the spring's elasticity resistance is lowered, which causes the operation error, the precision is lowered, and the malfunction occurs, and it is pointed out as a factor of the unit cost increase by requiring the assembly of skilled workers in the manufacturing.

The present invention was devised to solve this problem in consideration of the above-mentioned conventional problem, and compactly constitutes a component such as an elastic member fixed to the cover side in order to fully unfold the mirror, thereby saving the overall space and converting the forward and reverse rotation means of the driving motor. By improving from mechanical devices to electronic control devices using relays, it guarantees safe operation due to frequent reverse conversion of the driving motor and greatly reduces the overall volume to provide a safety mirror for the rear of the car, which achieves compactness of the safety mirror for the rear of the car.

First, the general matters and the main structure of the present invention will be described with reference to FIG. 1. In this figure, reference numeral 10 denotes a main body manufactured to correspond to a conventional spoiler shape and attached to a spoiler of an automobile. In the main body 10, a recess 11 is formed so that various components of the present invention are mounted. Moreover, the rear part of this recessed groove part 11 becomes the partition 13, the left and right edges become the locking groove 15 over the whole width direction, and the stopper 82 is formed in the side wall of the recessed groove part 11. As shown in FIG. These partitions 13 and the engaging groove 15, as described later, have a very important function in the slim operation of the present invention.

The stopper 82 may be formed on both sides of the side wall of the concave groove 11, or may be formed on one side wall.

A driving motor 12 for driving the safety mirror of the present invention is disposed in the recess 11 of the main body 10, and a main gear 14 is attached to the output side of the driving motor 12 and the main gear ( A driven gear 16 to mate with 14 is provided on the first shaft 18 coaxially with the output shaft of the drive motor 12.

Reference numerals 18a and 18b denote first brackets for fixedly holding the first shaft 18.

On one side of the first shaft 18, that is, on the other side of the main gear 14 and the driven gear 16, a forward and reverse conversion unit 20 for forward and reverse rotation conversion of the drive motor 12 is provided. The reverse conversion unit 20 includes a coil spring 22 elastically wound around the first shaft 18 and two pairs of limit switches 24 disposed on both sides with the first shaft 18 therebetween. It consists of (25).

Both ends of the coil spring 22 are elongated to form contacts 22a and 22b, and the contacts 22a and 22b are contact pieces 24a of the limit switches 24 and 25, It is comprised so that it may contact the upper surface of 25a.

Both ends of the first shaft 18 are provided with a pair of driving tables 36 for driving the safety mirror 30. This drive table 36 is preferably composed of a thin steel wire. The other side of the drive table 36 is fixed to one side of the lid 50 so as to allow free rotation.

Prior to explaining the attachment structure of the drive table 36, the cover 50 of the present invention will be described. The cover 50 has a substantially rectangular shape corresponding to a typical spoiler shape. However, the cover 50 is not necessarily limited to such a structure, and the cover 50 is manufactured to correspond to the spoiler's numerous designs such as convex or oval shape corresponding to the spoiler's design. .

The drive table 36, the second bracket 42 and the second shaft 44 is made of a steel wire or shortened the length of the parts in order to compact the overall size of the safety mirror for the rear of the car and to facilitate manufacturing have.

In the present invention, for the sake of simplicity in the description, in the drawing, the rectangle is simplified.

The safety mirror 30 is mounted inside the cover 50. This safety mirror 30 preferably employs a convex mirror to effectively convey a wider range of rear conditions of the vehicle to the driver and to eliminate blind spots.

The lower side of the cover 50 is provided with an elastic actuator 40 for holding and supporting the drive table 36 and for smoothly opening and closing the safety mirror 30.

The elastic actuator 40 has a second bracket 42 composed of a total of two pairs of two, two on one side of the cover 50, and a second shaft (42) provided between the second brackets (42). 44 and a coil spring 60, which is an elastic member elastically installed on the second shaft 44. As shown in FIG. This coil spring 60 may be provided in each of the 2nd shafts 44, and may be provided in only one side.

Referring to FIG. 3, the coil spring 60 is supported by one end 62 in contact with the driving unit 36 and the other end 64 is extended from the coil spring 60 to form a cover 50. By making it contact with the inner surface, the elastic force acts in the direction which always opens the said lid | cover 50. As shown to FIG.

Reference numeral 70 denotes a warning light that is turned on when the brake pedal is operated, 72 denotes a cover body for concealing the components, and 74 denotes a rear cover of the cover body 72 to easily illuminate the light of the warning lamp 70 to the outside. It is a see-through window.

With reference to FIG. 2, the structure which employs the relay system as the reverse conversion unit 20 of this invention is demonstrated. The relay as an example of the reverse conversion unit 20 used in the present invention is a conventional power relay. The relay 80 is provided with a semiconductor element having a common line, a positive line, and a negative line to supply the forward and reverse drive signals to the drive motor 12 in order to divide the rotation of the drive motor 12 into a forward rotation and a reverse rotation. It is a relay having a limit switch contact that operates by converting a physical load into an amount of current so as to prevent breakage of each operating part when the safety mirror 30 is fully opened or closed.

With reference to Figure 4 will be described another embodiment of the elastic member of the present invention.

This elastic member is a case where the tension spring 68 is used. That is, as shown in FIG. 5, one end of the tension spring 68 is connected to the outer end (lower end of the cover) of the second shaft 44 in order to always act in the open direction. It is a structure formed by fixing the other end to the drive table (36).

Reference numeral 38 denotes a tension spring hook hole formed in a portion of the drive table 36, and 52 denotes a tension spring hook hole formed below the cover 50, respectively. However, these hook holes 38 and 52 are not limited to such a hole system, and the second shaft 44 so that the elastic force of the tension spring 68 acts in a direction such that the cover 50 is always open. Any structure can be adopted as long as the structure is installed with a space between them.

As an example, the tension spring 68 may be installed by forming a locking protrusion under the cover 50 or the driving table 36. It is important to adopt a structure in which the elastic force acts in the direction in which the tension spring 68 always opens the cover 50. Even in this configuration, the same effect as the coil spring 60 shown in FIG.

Next, the operation of the safety mirror for the rear of the vehicle of the present invention configured as described above will be described with reference to FIGS. 5 to 9.

As shown in FIG. 5, the driving motor 12 reversely rotates in a direction in which the safety mirror of the present invention does not operate, that is, the cover 50 is closed, and thus, the outer surface of the spoiler and the outside of the cover 50. Explain from the state that the surfaces match.

In this state, when the main gear 14 is rotated in reverse, the driven gear 16 rotates in the direction of the arrow so that the lower end 54 and the upper end 56 of the cover 50 are mounted on the spoiler. It is in a state of being completely in contact with the upper surface of the partition 13, the locking groove 15 and the cover body 72.

In this state, although the coil spring 60 acts in the direction in which the cover 50 is always opened, the main body 10 because the driving force of the drive motor 12 acts more strongly than the elastic force of the coil spring 60. The lower end 54 and the upper end 56 of the cover 50 are completely in contact with the rear partition wall 13 and the locking groove 15 at the edge so that the cover 50 does not protrude to the outer surface of the spoiler. It does not affect the spoiler's function in normal driving.

In this state, the operation of opening the lid 50 will be described. For convenience of description, the relay type reverse rotation converter of FIG. 2 will be described as an example.

When the reverse gear is put in order to reverse the vehicle or park the vehicle in the state of FIG. 5, a switch (not shown) is turned on in response to the operation of the reverse gear, and the relay 80 turns on the reverse gear contact switch. The semiconductor device generates a predetermined forward and reverse drive signal, and among these signals, the reverse rotation signal (or forward rotation signal, hereinafter, the forward rotation when the cover is closed and the reverse rotation when the opening is defined as reverse rotation) is defined by the drive motor ( 12). As shown in FIG. 6, when the driving motor 12 starts to rotate in reverse, the driven gear 16 rotates in the opposite direction to the direction of FIG. 5 (small arrow direction) to push up the driving unit 36.

In the situation of FIG. 6, when the cover 50 is in close contact with the partition 13 or the locking groove 15 by the driving force of the driving motor 12, the coil spring 60 is operated by the action of the coil spring 60. The cover 50 is shown to be slightly lifted up.

If the driven gear 16 continues to rotate in this state, since no restricted force is applied to the coil spring 60, the elastic force is fully exerted to transfer to the state of FIGS. 7 and 8 and finally shown in FIG. As it is, the vehicle is fully deployed to provide the driver with obstacles behind the vehicle.

In the state of FIG. 9, that is, even when the cover 50 (safety mirror 30) is opened to the maximum, the drive motor 12 continues to rotate, but the stopper 82 formed on the side wall of the concave groove 11. Since the driving unit 36 is in contact with the driving unit 36, the driving unit 36 no longer rotates, and thus the driving motor 12 is loaded. At this time, by stopping the input of the power supplied to the drive motor 12 by the limit switch in the relay 80 that operates by converting the physical load amount into the amount of current, the drive motor 12 is stopped and all the operations are stopped.

On the other hand, if the driver operates the transmission gear to the parking position ('P' position) or the neutral position ('N' position), the relay is changed from the on state of the switch-on operated when the reverse gear is inserted to the off state. In the semiconductor device within 80, a negative signal is supplied to the drive motor 12 so that the drive motor 12 rotates in the direction of closing the lid 50 as opposed to the opening direction described above.

At this time, if the cover 50 is completely closed, the load is applied to the drive motor 12, and at this moment, the power supplied from the relay 80 to the drive motor 12 is cut off and the drive motor 12 is stopped.

As such, the present invention improves the mechanical device using the limit switches 24, 25, coil springs 22, and the like, which are conventionally used for safety mirrors for automobile rears, to electronic devices, thereby making the whole device compact. Moreover, the whole apparatus is miniaturized by employing the coil spring 60, the 2nd bracket 42, and the 2nd shaft 44 which also have the structure which spreads the safety mirror 30 on the cover 50 side completely.

Meanwhile, the present invention may employ the coil spring 60, the second bracket 42 and the second shaft 44 in the manner of using the limit switches 24 and 25 as the conventional forward rotation conversion means. It goes without saying that it may be.

As described above, according to the safety mirror for the rear of the present invention, a compact elastic structure is installed on the cover side of the mirror and the drive table is made of thin steel wire so that the mirror is fully opened when the mirror is opened. When closed, it is fully closed to enhance the appearance and ensure slim operation.The relay drive method is adopted as the forward and reverse conversion unit of the driving motor, which reduces the number of parts and makes the whole device compact and causes the malfunction of the conventional mechanical device. It is an excellent design that eliminated it.
