1 is a perspective view showing the basic configuration of a blade device for vehicle detachment according to the present invention.

As can be seen from Figure 1, the vehicle detachable blade device according to the present invention is basically composed of a fixed plate 10, a blade 20, and a combination, the blade 20 in the direction of up and down, left and right, and before and after It is characterized by being able to flow freely.

The vehicle detachable blade device according to the present invention is used to be coupled to the front end of the vehicle, the vehicle to which the vehicle detachable blade device may be mounted may be a variety of vehicles such as trucks and tractors.

The fixed plate 10 is coupled to the front end of the bumper or the like of the vehicle so that the blade 20 can be connected to the vehicle through the combination, and has a panel shape, but one side is bent, that is, the panel is folded in half. As seen from the side, it is bent like a 'b' and includes a vertical plane and a horizontal plane. The vertical surface of the fixing plate 10 is coupled to the lower portion of the front (front end of the vehicle) of the bumper and the horizontal surface of the fixing plate 10 is attached to a part of the lower surface (bottom surface of the bumper) of the bumper, that is, The inner surface of the fixing plate 10 formed is coupled to some surfaces of the bumper.

The reason for forming the fixing plate 10 in a shape similar to the letter 'a' is that it is more firmly and easily attached along the bent surface of the lower bumper of the vehicle than the one formed as in the prior art, thereby improving the fixing force. The shape of the fixing plate 10 may also be modified according to the shape of the bumper of the vehicle to be attached.

The fixed plate 10 functions as a means for allowing the cylinder assembly and the blade 20 to be connected to the vehicle by the inner side attached to the bumper of the vehicle such as a truck and coupled with the coupling on the outer side.

The blade 20 has a rectangular panel-like shape and directly touches snow or construction sand, and moves forward with the vehicle according to the speed and direction of the vehicle, and pushes snow or sand. . The blade 20 may be formed to be flat, but the curvature of the central portion of the blade 20 in order not to obstruct the driver's field of view as the snow or sand pushed by the blade 20 rises into the air by pressure. It is more preferable to form to form a role to limit the path so that the material such as rising snow or sand can be lowered again.

The outer surface (surface not in contact with the vehicle) of the fixing plate 10 and the inner surface of the blade 20 (that is, the surface which is not in direct contact with snow, sand, etc., the inner surface of the device) are connected to the assembly to connect the fixing plate. 10 and the blade 20 to be connected in a spaced apart state, the combination includes a cylinder assembly.

Each cylinder has a structure similar to that of a known hydraulic cylinder, which is configured to expand and contract by receiving a predetermined flow rate from the first, second, and third hydraulic generators. The first, second, third, and third cylinders 41, 42, and 43 are formed between the fixed plate 10 and the blade 20, but are formed at different positions to independently expand and contract each of the blades 20. It is configured to flow, and consists of three pairs to allow the blade 20 to operate organically with each other as well as up, down, left and right, and to flow in many other directions.

As shown in FIG. 1, the first cylinder 41 is formed between the first region 41a on the blade 20 and the fixed plate 10. The first cylinder 41 pushes or pulls the blade 20 due to a basic stretching action. Play a role.

The second cylinder 42 is connected to the second region 42a, which is a region wider than the first region 41a as a portion spaced apart from the first region 41a by a predetermined distance, that is, the pair The space between the pair of second cylinders 42 is spaced apart from each other than the distance between the first cylinder 41 of each other can be formed. The second cylinder 42 extends and contracts the organically associated with the first cylinder 41 and serves to flow the blade 20.

Particular portions referring to the first region 41a and the second region 42a are not limited to the portions shown in the drawings, and may be changed to other portions on the blade 20 as necessary. .

The third cylinder 43 is connected between both sides of the blade 20 and the fixed plate 10, the both sides are the middle left and right ends of the inner surface of the blade 20 as shown in FIG. It means the side. The third cylinder 43 basically changes the hydraulic pressure of each cylinder to allow the blade 20 to flow left and right as if twisted.

The detailed action of each cylinder and the angle change of the blade 20 due to the action described above will be described later.

The rotating device 50 is formed at one or both ends of any one of the cylinders to allow each cylinder to rotate, and includes a support member 51, a rotating part 52, and a motor. do.

The support member 51 is connected to the fixing plate 10 or the blade 20 and the like so that the pivoting part 52 can be firmly connected to support the pivoting force of the pivoting part 52. . As shown in the drawing, the supporting member 51 is a pair, and the pivoting portion 52 is connected and fixed by using a fastener 36 in the space therebetween. The support member 51 may be a panel having a similar shape to a triangle having a through hole at one side as shown in FIG. 1, but may be made of a bracket or the like.

In particular, the rotating part 52 includes a rotating shaft and a bearing, a friction joint, and a stopper so that the cylinder can be rotated at a predetermined angle by being connected to one or both ends of the one cylinder. The angle of each cylinder can be adjusted by rotating the rotating shaft by a bearing or the like. In addition, by using the rotation shaft, the movement of pushing or pulling the cylinder can also be performed to rotate the cylinder in more various directions.

The motor is a power means provided to transmit a driving force to the rotating part 52, and when the controller 100 receives a predetermined signal, the motor provides power to rotate the rotating shaft a predetermined number of times, and the rotating part 52 The motor is driven in accordance with the signal received from the controller 100 without infinite rotation has a certain angle.

The motor may not be provided as necessary. At this time, the rotating unit 52 may be adjusted by manual means other than the motor, that is, the stopper hinge.

As described above, the rotation device 50 is not infinitely rotated as described above, but is normally fixed, and when the angle of each cylinder is to be adjusted, the rotation angle is controlled by the controller 100 which will be described later. Is rotated by a predetermined range according to the direction and angle to be moved, the detailed configuration and operation of the rotating device 50 is similar to that known in the prior art, a more detailed description thereof will be omitted.

By providing the rotation device 50, any one, one or more of the first, second, third, and third cylinders (41, 42, 43), as well as the linear motion as a basic function as well as a certain level of rotational movement bar In other words, in addition to the movement of changing the angle in place, it is also possible to pull or push the respective cylinders to the rotation device 50 side, and to move in more various directions and angles so that the blade 20 Can be flown at more various angles.

The first, second, and third hydraulic pressure generating devices are composed of a pump, a motor, a tank, a valve, an oil pipe, and the like to generate a predetermined hydraulic pressure, and serve to transmit hydraulic pressure to the respective cylinders. In particular, the oil pipe should be connected to one end of each cylinder at its end. Since the rotation device 50 is connected to the end of each cylinder, the oil pipe is formed to be flexible so that the rotation device 50 can be connected. It is to be connected to the end of each cylinder.

The first, second, and third hydraulic pressure generating units generate constant hydraulic pressure and discharge the first, second, and third cylinders 41, 42, and 43, respectively. Power source supplied from the vehicle, that is, operated by a battery provided in the vehicle. Since the oil pressure generating device is a known technology, a detailed description of the detailed configuration and operation will be omitted.

Each of the hydraulic generators may be attached to one side of the fixed plate 10, or one side of the combination, and the like, and the position of the hydraulic generators may be adjusted as necessary and is not limited to a specific place.

Figure 2a is a planar action diagram showing that the blade according to the invention flows to the left and right, Figure 2b is a perspective action diagram showing that the blade according to the present invention is lifted, Figure 2c is a blade according to the present invention flows back and forth It is a side action figure which showed that.

2A, 2B, and 2C illustrate some of the various directions in which the blades 20 can move for better understanding, and the blades 20 are free in many directions and angles not shown in the figure. It can of course be flown into the material. Direction words used in the following description are all based on the respective drawings.

As can be seen from Figure 2a, the blade 20 can flow from side to side in the direction of the arrow shown in Figure 2a. When explaining an embodiment of such a left and right movement, a pair of third cylinder 43 The left and right angles of the blade 20 may be adjusted in such a manner that any one of the cylinders contracts and the other cylinder extends. At this time, the first and second cylinders may not be stretched and rotated, but may be organically moved together for smoother left and right movement.

In the above-described left and right motion, when the blade 20 is disposed in parallel with the bumper of the vehicle, snow or sand continuously accumulates in front of the blade 20 and the vehicle is difficult to operate due to a load on the vehicle. To prevent, by adjusting the left and right angles of the blade 20 to allow more efficient progress during snow removal, ice making and flattening operation. In other words, by arranging the blade 20 inclined at an angle so that the blade 20 is not parallel to the bumper of the vehicle, snow or sand, which is pushed in front of the blade 20 during operation, moves easily outside the blade 20. To be.

In addition, the blade 20 may be raised and lowered as shown in FIG. 2B, by lifting and lowering the blade 20 in such a manner that the pair of third cylinders 43 extends or contracts together. Lifting motion can be made. At this time, the rotating device 50 provided at one or both ends of the third cylinder 43 should also be rotated in a direction in which the blade 20 can be lifted, and the first and second cylinders are also made of the first and second cylinders. The three cylinders 43 will be stretched and shrunk to a certain level to assist in supporting the load of the blade 20 to distribute the force.

In addition, the first, second, third, and third cylinders 41, 42, 43, and the rotating device, in which the lifting and lowering movements are performed in the left and right portions of the blade 20 based on FIG. It is also possible to operate 50 organically.

By performing such various lifting movements, the blade 20 is lifted upward to facilitate the movement of the vehicle when the snow removal, ice making, and flattening operations are not performed. On the contrary, when the blade 20 is in contact with the road surface. By doing so, a work preparation state can be achieved, and even when the road surface is formed to be inclined, the work can be stably performed in compliance with the road surface without being applied to a portion of the blade 20.

Figure 2c shows the front and rear motion of the blade 20, the blade 20 is rotated back and forth on the basis of the imaginary axis of the horizontal direction of the blade 20 in the direction of the arrow shown in FIG. You can do the same exercise. This movement consists of the organic operation of the first and second cylinders. When the first cylinder 41 is extended and the second cylinder 42 is retracted, the upper side (as shown in the drawing) of the blade 20 is shown. The right side of the blade 20 moves to the left side of the drawing. In addition, when the first cylinder 41 is contracted and the second cylinder 42 is stretched, the upper portion (based on the drawing) of the blade 20 moves to the left side of the drawing, and the lower portion of the blade 20 is shown in the drawing. Move to the right of. In this way the blade 20 is capable of forward and backward movement as shown in FIG. 2C.

The above-described forward and backward motion, when the blade 20 is encountered with the obstacle of a certain size in the process of advancing with the progress of the vehicle, so as to avoid the obstacle by rotating back and forth based on the virtual axis. That is, it is usually fixed so that the blade 20 can push out snow and sand on the road, but when encountering the obstacle, the lower portion of the blade 20 is pushed toward the vehicle side so that the blade 20 rises to a certain height so as not to contact the obstacle. By doing so, the blade 20 serves to prevent damage or damage.

The three directions described with reference to FIGS. 2A, 2B, and 2C are only an example, and the blade 20 may flow in various directions as well as the three directions. In this process, the first, second, and third cylinders (41, 42, 43) and the rotating device 50 move organically with each other and move in various directions and angles.

In addition, the shapes of the first, second and third cylinders 41, 42, and 43 may be the same as the shapes of the respective reference numerals shown in FIGS. 1 and 2A, 2B, and 2C, but may be elastic according to their function and role. Of course, it can be modified as is not limited to a particular shape and location, etc., of course.

In order to operate the respective cylinder and the rotating device 50, it will be obvious that a controller 100 for controlling the respective cylinder and the rotating device 50 should be provided, and the detailed configuration of the controller 100 and The operation will be described later.

Vehicle detachable blade device according to the present invention made of the above-described configuration, so that the blade 20 may be flowed in various directions and angles, such as up and down, left and right, and front and rear, so that it can be performed more conveniently and easily will be.

In the above description, an example has been described to help understanding, but as described above, the movement of each cylinder and the rotation device 50 may be simultaneously performed, such that the blade 20 moves in various directions and angles to incline the road. B moves freely according to various external environments such as road curvature and obstacles, and is naturally seated on the road without damaging the blades 20. In addition, due to the operation of the respective cylinder and the rotation device 50, the blade 20 meets the obstacles and is damaged, such as when the debris, such as splashing of the debris is not created, it is possible to perform various tasks more safely and conveniently There is an advantage.

In addition, the blade 20 may include a load providing unit 30 in order to have a greater load.

3 is a perspective view showing the configuration of the load applying unit 30 according to the present invention.

As can be seen from FIG. 3, the load providing unit 30 includes first and second support panels, first and second weights, and washers 34, and the first support panel 31 includes the blades 20. The panel is similar to the panel formed to be bonded to the central portion of the inner surface of the inner surface (that is, the surface connected to the coupling frame), the second support panel 32 is formed to have a predetermined thickness of the first support panel 31 It is coupled to the upper surface, but includes a circular groove (32a) formed through the center portion so that the first weight 33 can be inserted, this circular groove (32a) is the first weight 33 so that the first weight 33 can be inserted It should be formed to have a diameter similar to the diameter of the first weight 33, the thickness of the second support panel 32 should also be formed to have the same thickness as the thickness of the first weight (33).

The first weight 33 is formed to have a diameter and thickness similar to that of the circular groove 32a formed in the second support panel 32. That is, the first weight 33 is fitted into the circular groove 32a and is seated so that the bottom surface is brought into contact with the first support panel 31. The first weight 33 is not provided with the second support panel 32 integrally. The circular groove 32a and the first weight 33 to have separate portions have different loads from each other, preferably larger than those of the second support panel 32 all made of the same material. The first weight 33 having a weight is inserted so as to more smoothly disperse the impact due to the external pressure.

The first weight 33 has a greater specific gravity than the first and second support panels 31 and 32 to perform the above-described impact dispersion function and at the same time add weight to the blade 20. It should be a heavy material.

The washer 34 is a round and thin metal plate generally inserted between the fasteners 36 when the article is removed with a fastener 36 such as a bolt or nut, and is usually made of the same metal as the fasteners 36. When the surface to be clamped is not flat, or when only the fastener 36 is used, the groove is formed on the surface, and the fastener 36 is used to dig into a soft material such as wood. In addition, when the fastener 36 comes loose due to the vibration, the bent end of the washer 34 is bent and the fastener 36 is pressed to prevent the fastener from loosening or to spring the washer 34 together with the spring washer. It is also possible to prevent the fastener 36 from loosening.

The washer 34 according to the present invention is formed to have the same diameter as the diameter of the first weight 33, and is seated on the first weight 33 so that the first weight 33 and the second weight are further increased. The first weight 33 can be prevented from being separated from the circular groove 32a of the second support panel 32 while being easily and firmly connected. In particular, the washer may have a thicker thickness than the general washer so that the circumferential surface of the second weight 35 to be described later is spaced apart by the thickness of the second support panel 32 and the washer. Let's do it.

The second weight 35 is formed to have a diameter larger than the diameter of the washer 34 is seated on the upper surface of the washer 34, that is, the circumferential surface of the second weight 35 is the second It is spaced apart from the support panel 32 at regular intervals, and has an empty space therebetween. The material is made of the same material as the first weight 33 or greater specific gravity than the first weight 33 so that the blade 20 has a greater load.

The first and second weights and the washers 34 may be provided with through holes 38 into which fasteners 36, such as bolts, may be inserted at positions corresponding to each other.

Referring to the operation example of the load applying unit 30, the first support panel 31 is coupled to the central portion of the inner surface of the blade 20, the first support panel 31 After the second support panel 32 is coupled, the first weight 33 is inserted into the circular groove 32a formed in the second support panel 32. After that, the washer 34 is mounted on the upper surface of the first weight 33, and the second weight 35 is seated on the upper surface of the washer 34.

In the coupling method of the load applying unit 30, the fastener 36 is inserted from the upper surface of the second weight 35, and the washer 34, the first weight 33, and the second support panel 32 are sequentially formed. It is preferable to penetrate and be connected to the end thereof to the first support panel 31. When the load applying unit 30 is coupled in the above-described manner, the space between the second weight 35 and the second support panel 32 is separated by the thickness (height) of the washer to create an empty space. As a result, when the pressure is applied from the outside, the second weight 35 may secure a space that may flow slightly in the direction in which the pressure is reacted to absorb the impact more easily.

By providing the load providing unit 30 in addition to give a certain level of load to the blade 20 can be flowed more stably under the pressure of the operation of each cylinder, when the impact is applied from the outside The load-providing part 30 made of a material different from the weight of the blade 20 absorbs and distributes the impact so that the blade 20 can receive the minimum impact, thereby minimizing the unexpected situation due to external impact during the operation. And, by having its own load to be closer to the road surface to facilitate the operation.

In addition, the diameter of the first weight 33 may have a diameter slightly smaller than the diameter of the circular groove 32a, which allows the first weight 33 to flow slightly in the circular groove 32a. In order to have a space that can be made, as described above, when the diameter of the first weight 33 is adjusted, it is caused by the difference in diameter between the first weight 33 and the circular groove 32a when the external shock is impacted. This is because it can flow in space and distribute the impact more smoothly.

With the above configuration, the snow removal, ice making, and flattening operations can be performed more safely and efficiently, but it may be troublesome in that the driver needs to control the cylinders. In other words, if the vehicle suddenly finds an obstacle when moving forward at high speed, there is a fear that the blade 20 may be damaged if the driver controls the respective cylinders late.

In order to solve this problem, the vehicle detachable blade device according to the present invention includes a pressure sensor to allow each cylinder to flow automatically, and may include an additional configuration in the controller 100.

4 is a block diagram showing the configuration of the controller 100 according to the present invention.

The controller 100 may be provided at the periphery of the cylinder assembly, but in order to be able to operate more safely, it may be more preferable that the controller 100 is connected to the cylinder assembly through a cable. The power of 100 is taken from the power that can be generated in the vehicle.

In order to operate the controller 100, a pressure sensor must be provided as a whole, and a plurality of pressure sensors may be provided on the one surface of the blade 20, which is spaced apart from each other to push the eyes. It is preferable that a plurality of blades 20 are provided on the lower side (surface side in contact with the floor of the road) particularly susceptible to impact. The pressure sensor senses a pressure applied to the blade 20 at each point to generate a pressure value signal, and each generated pressure value signal is connected to a controller through a cable provided along the coupling frame. 100).

The controller 100 includes a pressure sensing module 110, a reference impact value database 130, an integrated determination module 150, and a driving control module 160.

The pressure detecting module 110 receives the pressure value signal from the pressure detecting sensor and transmits the pressure value signal to the integrated detecting module.

The reference impact value database 130 includes a critical impact value at which the blade 20 of the vehicle detachable blade device according to the present invention is not damaged.

The integrated determination module 150 calculates the impact value by using the pressure value transmitted from the pressure sensing module 110 as a parameter, and compares the cylinder to be currently operated and the amount of extension of the corresponding cylinder or the critical impact value of the reference impact value database 130. The shrinkage amount is determined, and the rotation angle of the rotation device 50 is determined.

The drive control module 160 receives a signal from the integrated determination module 150 to control the amount of expansion or contraction of the first, second, and third cylinders 41, 42, and 43, and the rotation device 50. This function controls the rotation angle of.

Referring to one embodiment according to the controller 100 described above, when the vehicle equipped with the vehicle detachable blade device according to the present invention advances at a specific speed, the slope or obstacles of the road to a predetermined portion of the blade 20, etc. When the pressure is applied by the pressure sensor detects the pressure to generate a pressure value signal to be transmitted to the pressure detection module 110, the pressure value signal is transmitted back to the integrated determination module 150, The integrated determination module 150 receives the pressure value to calculate the actual impact value applied to the blade 20, and determines the direction and angle to which the blade 20 should move in comparison with a critical impact value, and then controls the driving. Signals to the module 160 causes each cylinder to expand or contract and rotate so that the blade 20 automatically moves without damage and avoids obstacles. Lee will be capable of the task.

In addition, the controller 100 may include a speed sensor and a speed recognition module 120. The speed sensor serves to detect the speed of the vehicle. It may be a measuring device, it is also possible to additionally mounted on one side of the vehicle to detect the speed of the vehicle. The speed sensor generates a speed numerical signal and transmits it to the speed recognition module 120 through a cable.

The speed recognition module 120 receives the speed numerical signal from the speed sensor and transmits the speed numerical signal to the integrated determination module 150.

By including the speed sensor and the speed recognition module 120, the integrated grasping module 150, each of the speed and pressure values received from the speed recognition module 120 and the pressure sensing module 110 as parameters. The numerical values are weighted, and then the shock values according to the speed and pressure are calculated as the summed values. The weight may be applied differently according to the purpose of use of the vehicle detachable blade device according to the present invention, that is, snow removal, ice making, or flat work.

By additionally including the speed sensor and the speed recognition module 120, the impact value applied to the blade 20 can be more precisely calculated and thus can work more stably.

Referring to FIG. 2C as an example, when a vehicle encounters an obstacle and the pressure sensor included in the blade 20 senses a pressure, the pressure sensor 110 transmits the pressure to the pressure detection module 110. The speed at which the vehicle is driven is determined and transmitted to the speed recognition module 120. The speed value and the pressure value signal are transmitted to the integrated determination module 150 again. The speed determination value and the pressure value are received by the integrated determination module 150 and weighted to each value to be applied to the blade 20. Loss yields the actual impact value.

According to the impact value calculated by the above-described process, the drive control module 160 by grasping the amount of extension of the first cylinder 41, the amount of shrinkage of the second cylinder 42, the angle of rotation of the rotation device 50, and the like. By sending a signal to each cylinder is stretched or contracted and rotated so that the upper side of the blade 20 to move forward, the lower side to move backward to avoid obstacles.

As described so far, the configuration and operation of the vehicle detachable blade device according to the present invention have been expressed in the above description and the drawings, but these are merely described as examples, and the spirit of the present invention is not limited to the above description and the drawings. Various changes and modifications are possible without departing from the spirit of the invention.
