Description

1 TARIFF A camera carrier with tip-over safety features. Technical Area This invention aims to prevent the camera from tipping over and / or in wheeled camera transport systems. A tilt safety feature 5 reduces the likelihood of damage to the camera in the event of a tilt. It relates to the camera carrier that has the system. State of the Art Camera movement is used in many situations where the object being filmed is moving. It is a necessity. Systems developed for camera movement have many and diverse features. 10 that move on rails, move around articulated joints, or are wheeled There are many pieces of equipment that are moved on the ground using these systems. One known example in the field is the Japanese patent JP2011063241A belonging to Honda Motor. This is explained in the application. The application in question refers to an inverted pendulum with 2 or 1 wheels. The text refers to a movement system that allows the user to stand upright using a model. The systems are basically designed to prevent the load on them from tipping over during back-and-forth movements. the load tilts in the direction of motion and then reverses direction due to acceleration before coming to a stop. They possess anti-tipping kinematic properties related to their backward tilting. Purpose and Brief Description of the Invention The purpose of this invention is a mobile carrier that carries the camera on wheels. To ensure the camera's safety in case it tips over, the impact of the collision is measured at 20°C. The invention is the development of an air-propelled safety system that will mitigate the effects of air propulsion. the camera thanks to the system itself and / or the propeller guard cage system It also aims to ensure safety. The invention also eliminates the possibility of tipping over. air propulsion system for lifting and / or damping sudden and minor shocks It also aims to be used. 25 The invention is a camera that is inverted and carried on a mobile platform with two or one wheel. By their very nature, inverted pendulum systems are tilted in the direction of motion. It is stationary. While in motion, the load does not need to be tilted forward; it remains vertical. One of the aims of the invention is to create a stabilizing thrust to maintain its position. 2 Definitions of the Figures Illustrating the Invention This invention, which developed a camera carrier with tilt protection, is a better example of that invention. The diagrams and related explanations used to illustrate this are given below. Figure 1 Schematic of a camera carrier with tilt protection according to the invention.

Linear thruster 5. Lateral thrust 6. Linear guard 20 7. Lateral protector 8th leg Detailed Description of the Invention The subject of the invention, the camera carrier (1), in its most basic form is a one or two-wheeled vehicle. 25 It includes a column (3) positioned vertically on the platform and a camera (2) at its end. The movement platform structure is vertically balanced because it rests on the ground at one or two points. It cannot remain. The wheel or the motor or motors that enable the movement of the wheels. To prevent the platform from tipping over, it must continuously move forward in the “x” direction and backward in the “-x” direction. 3 It provides balance. This balance, achieved by motor thrust, is like an inverted pendulum. It is called a pendulum system. Forward and backward motor movements eliminate the possibility of tipping over while standing still. During the movement (x), it overturns the load on it in the direction of movement. Vertically A transported load is subjected to two different forces. The first of these is the force acting on the ground. The load on the system will be overturned by "-m" due to inertia. The second is the friction of the air hitting the vertically positioned load during movement. There is a possibility that the force Fs will again push the load back "-m". Both forces The load, tilted forward to dispose of the load in an "m" position, is positioned away from its center of gravity. It creates a force in the forward direction. Since this force is Fgx = Fa + Fs, the camera carrier (1) 10 There will be no tipping over while moving in the forward (x) direction. However, any irregularities in the ground, such as an electrical cable getting caught on a wheel or... It is possible to attach the wheels. Whether single or double, the cable's direction of movement is marked "x". If the load is positioned angularly with "-x", then the load will tilt to the right "-n" or to the left "n". There is a possibility. Angularly positioned obstacles, in particular, pose the greatest risk. These are the elements. The weight rising from the ground due to a long column (3) and a heavy camera (2). increasing the oscillation of the central system and encountering a second obstacle during movement If the resonance frequencies coincide, the oscillation amplifies. A collapse is inevitable. However, inverted pendulum systems only utilize the motor force applied to the wheels. They have the ability to stop these oscillations, especially in the left "n" and right "-n" directions. Damping of oscillations is not possible in single or double wheel systems. Advanced In "m" and reverse "-m" oscillations, this can be partially prevented in single or double wheel systems. However, as the column (3) length increases, the damping effect is delayed. An additional force is needed to dampen the oscillation. This force is applied to the environment at 25°C. Fxh and Fyh are supplied with air which can be loaded and propelled forward “x” and backward “-x” by propellers (4 and 5). will be. Linear thruster (4) and lateral thruster attached to the column (3) near the camera (2) (5) thanks to the displacement of the air, a thrust caused by air thrust in all directions The force will be created. If the camera carrier (1) is tilted in any direction, the relevant 30 4 an air thrust is created in that direction, counteracting the tilting motion in that direction. will be created. With this thrust force created before the tipping over, the camera (2) hit the ground rapidly. This will be prevented. To understand this overturning, look at the column (3), look at the camera (2). or an angle gauge, accelerometer or tilt switch attached to the platform relevant 5 It will prevent a rapid impact by creating air thrust in that direction. The invention also includes a linear thruster (4) and a protective cage with a linear impact moment. collision with the lateral ejector (5) and the lateral ejector (7) with the protective cage (6). It will have an effect that reduces its impact. In addition, the operating speeds and thrust directions of the linear thruster (4) and lateral thruster (5) are 10 By adjusting, controllable force values ​​Fxh and Fyh can be obtained. These forces... Thanks to precise control, the column (3) cannot tilt or fall in any direction. The tilting / coiling position can be reversed. Even without a full tilt / coil, just... In the event of an earthquake, measures should be taken to prevent such earthquakes in the direction of the earthquake. Fxh and / or Fyh cause the column (3) to come into equilibrium by disrupting the shaking frequency of an additional force column (3). It can provide. In the preferred application of the invention, the linear thruster (4) and the lateral thruster (5) are as follows: will be activated in the situations and the camera (2) shooting quality, viewpoint and tilting This will prevent it. Accordingly; - The camera (2) is placed by fully tilting the column (3) on the camera carrier (1). If it tips over in a way that causes it to hit the ground, it should be perpendicular to the direction of impact. and / or by creating an angled air thrust towards the ground with Fxh and / or Fyh forces to prevent the camera (2) from hitting the ground violently. - The column (3) on the camera carrier (1) is tipping over or about to tip over If it starts, the camera (2) must maintain its position before it tipped over 25 by creating air thrust perpendicular and / or at an angle to the tipping point, Fxh and / or Fyh to ensure that the camera (2) returns to its position before the tipping over with its forces. - The movement of the column (3) on the camera carrier (1) of the camera carrier (1) Tremors caused by the nature of the mechanism or by ground conditions, Due to tremors, the camera (2) may shake. These tremors themselves or 30 air thrust in any direction to prevent possible resonances by creating Fxh and / or Fyh forces and vibrations of the camera (2) To ensure it is damped. Camera carrier (1) body Fm during movement of the system in any direction It is expected to tilt in the direction of movement. This is because tilting in the opposite direction of movement is 5 It is the counteractment of the inertial force (F) generated in the correct direction of motion. Due to the tilting, the camera (2) viewpoint will shift forward and downward. In particular, by equating the force Fxh to the force Fa, the column (3) moves to the ground plane. However, it will be ensured that it remains upright. Within the scope of the invention, the control of air thrusts created by linear thruster (4) and lateral thruster (5) 10 A control unit can be used for this purpose. This control unit is the camera. position, angle, angular velocity, angular acceleration of the carrier (1), column (3) and / or camera (2), using at least one of the linear velocity and / or linear acceleration information, linear thruster (4) and / or check the working status of the lateral thruster (5). For this purpose, one or more accelerometers, gyroscopes, tilt sensors are mounted on the camera carrier (1). It may include a sensor, angle sensor, inertial unit (IMU) and / or tilt sensor. Using the data obtained from the sensors in question, the vertical position of the column (3) was determined. The amount of deviation and / or the direction of deviation can be determined. The control unit determines the specified deviation. linear thruster (4) and / or lateral thruster to create a corrective moment in the opposite direction. It can operate the pusher (5). 20 The magnitude of the thrust forces generated by the linear thruster (4) and the lateral thruster (5) is constant. It is not necessary. The rotational speed, operating time and / or thrust direction of the thrusters can be controlled. by applying a variable magnitude thrust force depending on the movement state of the column (3). This can be achieved by applying low thrust forces even with small amplitude vibrations. If the tendency to tip over increases, a higher thrust force can be generated. 25 The control unit measures not only the current angular position of the column (3) but also its angular velocity and / or It can also take into account the angular acceleration. Thus, column (3) has not yet reached the critical tilting angle. Linear thruster (4) and / or lateral thruster (5) are activated by determining the tendency to tip over before reaching it. This allows the air thrust to be applied not after the rollover has occurred, but during the rollover itself. It can be created by determining the likelihood of it starting or tipping over. 30 6 In one application of the invention, the control unit is the motor that provides the movement of the camera carrier (1). or is connected to the control system of the motors. The camera carrier (1) will accelerate, The information that it will slow down or change direction is transmitted to the control unit. The inertial force that the movement will create on the column (3) and camera (2) is not yet on the column (3) It can be determined without changing its position. Linear thruster (4) and / or lateral thruster (5) in question 5 It can be operated in a way that partially or completely counteracts the inertial force. Thus... the direction of movement of the column (3) during the acceleration and deceleration of the camera carrier (1) or tilting in the opposite direction of movement can be reduced and the camera (2) relative to the ground plane It can be held in the desired position. In another application of the invention, the linear thruster (4) and the lateral thruster (5) are independent of each other. It is controlled in this way. In this way, movements in the forward-backward and left-right directions are controlled separately. They can be balanced separately or simultaneously. The combined thrust forces in two directions. by creating a composite corrector in any direction between the x and y directions. Force can be obtained. Linear thruster (4) and / or lateral thruster (5) can generate unidirectional or bidirectional air thrust 15 It can be structured in a way that allows for bidirectional thrust, changing the direction of propeller rotation, and steerable. The use of air ducts allows for selective operation of multiple opposing propellers. This can be achieved by operating it in this way or through similar methods. The linear thruster (4) and the lateral thruster (5) are located in the upper section of the column (3) and near the camera (2). positioning, the generated air thrust to the tilt axis of the camera carrier (1) 20 This increases the distance between them. Thus, it provides a higher air thrust of the same magnitude. It is possible to obtain a corrective moment. Within the scope of the invention, linear guards (6) and lateral guards (7) are used to protect the movable parts of the relevant thrusters. In addition to preventing the parts from coming into contact with the external environment, the camera carrier (1) from tipping over. It can be one of the first structures to come into contact with the ground or another element in the surrounding environment. 25 Thus the guards (6, 7) create a physical protection zone between the camera (2) and the ground. By doing so, it can reduce the likelihood of the camera (2) hitting the ground directly. In one application of the invention, the camera carrier (1) can also be mounted on one or more feet (8) It includes. The foot (8) protects the camera (2) and / or the camera carrier (1) in case the camera carrier (1) is overturned. It can be sized and positioned to contact the ground before the column (3). 30 7 Camera (2) with foot (8), linear guard (6) and / or lateral guard (7) It can create a protective impact boundary around it. The air-propelled balancing system described in the invention only covers complete rollover. not in preventing, but in the movement of the camera carrier (1) the camera (2) in space It can also be used to maintain orientation. In this way, the wheels are balanced. 5 resulting from movements, irregularities in the ground, acceleration and deceleration The effect of column (3) movements on the camera (2) image can be reduced.
