Description

{SAFETY SIGNAL ROBOT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic signal robot, and more particularly, to a traffic signal robot provided with a traffic signal or an induction signal on an unmanned road.

When traffic control such as road repair, subway construction, alcohol control, or sudden accident on other roads occurs, the traffic worker carries hand flag or stick light and controls traffic It sends a caution signal for safety to prevent a car accident.

However, such signaling may be dangerous, and signaling operations that are repeatedly performed for a considerable period of time may be laborious and tedious for the operator, Traffic signal devices have been developed and used.

Korean Utility Model Registration No. 20-0290412 discloses a traffic signal robot as a swing device for shaking a traffic control safety indicator. In this case, a safety indicator is installed on the mannequin's arm instead of the traffic worker. Such a traffic signal robot is also found in a number of patent and utility model registration such as a utility model registration No. 20-0318264.

In these devices, a motor and power transmission mechanism is built in near the arm of the mannequin to shake the safety indicator or flag. As the person looks more like a driver, more attention is paid to the arm, The joints of the shoulder joints and the elbow joints connecting the upper arm and the lower arm in the arm are bent in all directions. For example, it is possible to rotate the parts relative to each other around two rotary shafts perpendicular to each other in each joint part so that various complicated postures can be obtained. However, since the configuration is complicated, it takes time to install the parts and the production cost is increased.

However, it is sufficient that the existing traffic signal can easily operate the signal naturally like a person in only a few basic postures since the operation of shaking the arm easily takes the majority of the signal operation. When the traffic signal robot is manufactured, It is not necessary to have a complex joint structure like a robot.

Since the traffic signal robot is carried, installed and used among various construction sites, it is easy to receive an external shock during the handling or moving process, and even when the internal motor operation is repeatedly performed, Particularly, the joint between the shoulder and the arm, the joint between the upper arm and the lower arm of the arm, and the motor operation part provided around the joint, are damaged and become durable.

In the present invention, a nut (not shown) is fastened to a rotation shaft (bolt) at a position where the arm coupling part and the body coupling part are rotatably engaged with each other in a surface contact state, and a resilient cushioning material such as a compression coil spring, (The engaging portions on the side facing each other), and can buffer the impact in the direction of the rotating shaft, which may affect these engaging portions.

At this time, in the present invention, a plurality of holes or grooves are formed on the contact surfaces of the body-side engaging portion and the arm-engaging portion so as to accommodate the projections on one side and the projections on the other side, Stable mutual fixation can be achieved in the direction of rotation. The cushioning member, such as a spring, acts in such a direction that these engaging portions always come into close contact with each other, making it difficult to separate the projections and the holes, so that the state can be more stably fixed and maintained after the arm position is fixed.

In the present invention, the body-side coupling portion has a shape in which the inner surface of the body-side coupling portion faces upward while the contact surface with the arm-side coupling portion is twisted so that the front side of the robot extends slightly outward. have.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 and FIG. 2 show an overall skeleton configuration in a deployed state for a signal operation of a traffic signaling robot according to an embodiment of the present invention, and an overall skeleton configuration in a folded state for mobile storage.

The trunk portion 10 is formed of a skeleton in the shape of a rectangular frame, and a lower portion of the rectangle formed by the rectangular frame is formed of a horizontal shelf plate, and a regulating device 13 including a circuit portion for operating the traffic signaling robot is installed thereon .

A release switch 11 is provided at the lower end of the two body pipes corresponding to both sides of the rectangle and when the switch is pressed, the two leg pipes 21 of the leg 20 can enter or exit the trunk pipe . A spring is provided in the body pipe so that a gentle opening and closing operation can be performed when the leg pipe 21 goes in and out.

The lower end of the leg pipe 21 is fixed to the base 23 lying on the ground. At the front and rear ends of the base, a rod-like extension member 25 is rotatably fixed to extend from the ground to the front so as to stably stand the traffic signal robot on the ground.

The shoulder skeleton corresponding to the upper side of the rectangle constituting the trunk portion 10 is included in the shoulder portion 15 of the traffic signal robot and the head portion 50 is rotatable in a plane perpendicular to the shoulder skeleton at the center of the shoulder skeleton Is fixed. At the shoulder joint portions at both ends of the shoulder portion, the body portion 10 is engaged with the arm 30.

The arm 30 has an upper arm 31, a lower arm 35, and an elbow joint 33 which rotatably fixes them to each other while connecting them. A mechanical part such as a motor and a gear is installed on the elbow joint 33 and around the elbow joint 33 so that the upper arm and the lower arm are angled with each other and can perform a signal operation in which the arm is flexed or bent. Such a configuration is common to the traffic signal robot, and a detailed description thereof will be omitted.

Referring to FIGS. 3 to 5, the shoulder joint 15 'is provided at its both ends with a body side joint member 150 and an arm side joint member 310 to form a shoulder joint portion.

The body-side joining member is fixed to the shoulder frame 15 'and can be divided into a horizontal portion 151, a bending portion 153, and a body-side joining portion 155. Here, the body-side joining member is made of a long-formed steel or aluminum plate material. The horizontal portion is horizontally fixed with a screw or the like side by side with the shoulder skeleton, and the engaging portion 155, which is the portion passing through the bending portion 153, forms the bending portion 153 by being bent 90 degrees or more from the portion deviating from the shoulder bone, But not in a direct downward direction, but extends from the vertical direction to the body side by about 30 to 40 degrees more obliquely.

The front and rear direction of the traffic signal robot is the width direction of the body side joining member 150. Therefore, the inner surface of the body side of the body-side engagement portion 155 mainly looks toward the upper side while looking toward the body. At the same time, the torso-side joining portion 155 is slightly twisted so that the inner surface of the torso-side portion is somewhat directed toward the forward side of the traffic signal water-based robot.

And an arm coupling portion 311 of the arm coupling member 310 is coupled to the inner surface of the body side of the body coupling portion 155. The arm coupling member 310 also has a long plate shape, and the arm coupling portion 311 is in surface contact with the body coupling portion 155. These engaging portions 155 and 311 penetrate through substantially the center of the surface contacted portion and fixed to each other by a bolt body 411 serving as a rotating shaft.

The arm coupling member may also be divided into an arm coupling portion 311, a bending portion 313, and an arm coupling portion 315. The arm binding portion 315 is bent outward by about 130 to 150 degrees from the arm coupling portion 311 through the bent portion 313. [ Therefore, the arm binding portion 315 is bent so that the arm binding portion 315 is further upwardly elevated by about 10 to 20 degrees in the outward horizontal direction, and the bottom surface thereof is directed to the substantially lower outward side. The upper end surface of the arm 30 is joined to the lower surface of the arm binding portion. In this case, the arms extend in a slightly outward direction from the lower surface of the arm binding portion.

The bolt head 413 is fixed to the outer surface of the body side engaging portion 155 and the bolt head 413 is fixed to the outer surface of the body side engaging portion 155, The arm coupling portion 311 passes through the bolt body 411 but is freely rotatable about the rotation axis formed by the bolt. A nut 415 is provided at an end of the bolt body 411 opposite to the bolt head 411 and a compression coil spring 417 is provided between the nut 415 and the coupling portion.

In order for the robot arm to be lifted up close to the horizontal position in order to move the robot arm in the downward position, the robot arm is fixed to the body side around the bolt The protrusion 317 is formed on the coupling surface of the coupling portion 311 and the protrusion is inserted into the groove or the hole, The position of the arm 30 relative to the part 10 can be fixed. Of course, a hole or a groove may be formed in the body member on the opposite side to the projection.

Three holes may be provided for each position such that the center angle obtained by connecting the two holes adjacent to each other around the bolt as the rotation axis is 30 degrees so that the arms can be fixed in the rotation range of about 90 degrees, And can be installed in any required number of positions for each posture position suitable for the user.

Therefore, although the robot arm is directed downward (downward) from the body of the traffic signal robot standing in the storage posture in which the signal motion is not performed, it is slightly outward from the body, but when the robot arm is rotated by 30 degrees around the rotation axis (bolt) You can take a posture, a posture in which the arm is raised obliquely to the front and side, and a posture in which the arm is horizontally close to the side. In each of these postures, the mutual spreading and bending motion of the upper arm and lower arm centering on the elbow joint makes it possible to naturally induce signals or caution signals.

More specifically, considering the arm structure of the traffic signal robot and the structure of the shoulder joint, the arm of the lower part slightly outward is rotated 90 degrees about the rotation axis in the shoulder joint, In a posture with arms extended horizontally close to the outside, the arms are slightly downward and slightly rearward.

The robot arm itself has elbow joints in the middle, and a motor is installed around the joints, so that the joints are bent. Since the robot sends a signal as it is bent, when the robot is in front of the traffic signal robot on the road, When the joint is bent in the state, a hand or a warning light caught by the hand is raised horizontally, and then the signal operation is performed to bring it close to the horizontal or below the horizontal.

FIG. 6 shows a photograph of a skeleton structure as shown in FIG. 1, in which clothes and work clothes are put on as a traffic signal, a warning light 500 is installed, and a power source battery 600 is installed. As shown in Fig. 3, both arms of the ready-facing downward direction were rotated at different angles to perform signal operation. These signal behaviors appear to resemble the signal behavior of a person with a handwriting or a beacon.

Particularly, in this embodiment, since the engaging surface of the body-side engaging portion is twisted so as to be able to look forward partially at an angle of less than 30 degrees (0 to 30 degrees), preferably a small angle of about 5 to 15 degrees, The rotation of the arm naturally changes the orientation of the arm, so that it is possible to perform a natural posture change and a signal operation closer to human motion than a conventional posture change using a plurality of mutually orthogonal 90 degree joints.

In this embodiment, a compression coil spring 417 exists between the nut and the coupling portion around the bolt constituting the rotation axis, and the body coupling portion 155 and the body coupling portion 155 are formed in the direction of the bolt head 413 opposite to the nut 415 If the external force is not applied by pushing the arm coupling portion 311, they act to keep the contact at the contact surface with each other.

Therefore, when these engaging portions are relatively rotated around the rotating shaft (bolt), force is exerted on the rotating shaft in the direction of the rotating shaft to separate the pushing force of the spring and to separate them from each other, And then the protrusion approaches the other hole or groove at the desired position (arm position). Then, due to the pushing force of the spring, the projection is easily inserted into the corresponding hole or groove.

As a result, when the protrusion is once inserted into the groove or the hole, the compression coil spring stably maintains the state, and when the user does not intend, the arm coupling portion and the body coupling portion spontaneously rotate by the external force, In the case where the user intentionally changes the position of the arm, when the user rotates the two joint parts, the protrusion and the groove are fastened easily at the place where the projection and the groove or the hole meet, can do.

On the other hand, the compression coil spring provided around the rotating shaft (bolt) which engages the body-side engaging portion and the arm-side engaging portion of the shoulder engaging portion is formed in such a manner that, except for the case where the same force acts on the body and the arm, It is possible to alleviate the phenomenon that the joint portion and the joint portion are damaged and worn out.

In addition, when each arm or body part is moved by an external force or an internal signal operation, when a shock is applied, the shoulder joint part absorbs a part of the impact due to spring deformation and is restored to its original position. And the impact force acting thereon is relaxed.

Traffic signaling robots are transported, installed and used among various construction sites. Considering the fact that the traffic signaling robots are roughly handled and frequently hit during this process, Considering the fact that the robot is exposed to a shock from a change in operation, mounting the buffer member around the rotation axis of the shoulder joint portion as in this embodiment can reduce the possibility of damage to the traffic signal robot and enhance the durability, The shoulder joint portion, and the motor operation portion disposed at or around the elbow joint between the upper arm and lower arm of the arm can be reduced and the durability can be reduced.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. That is, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
