[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1-8 shown, an obstacle clearing tool for an off-road motor vehicle includes an obstacle clearing tool 1, a frame 2 and a mounting seat 3. In this application, the obstacle clearing tool 1 is replaced by a snow shovel, a snow plow or other tools for clearing obstacles. The frame 2 is installed between the obstacle clearing tool 1 and the mounting seat 3. The frame 2 includes a front arm assembly 21, a rear arm assembly 22 and an elastic connection assembly. The front arm assembly 21 and the rear arm assembly 22 are flexibly connected through the elastic connection assembly. A disassembly and assembly mechanism 5 is provided at the rear end of the rear arm assembly 22. The mounting seat 3 is detachably installed on the disassembly and assembly mechanism 5. The mounting seat 3 is installed at the bottom of the power device. A locking rod detachably cooperating with the disassembly and assembly mechanism 5 is provided at the bottom of the mounting seat 3. The power device is a motor vehicle, an off-road vehicle or other replaceable power devices.

[0021] The disassembly and assembly mechanism 5 includes a connecting frame 51, a locking hook 53 and a fixed hook 52. The fixed hook 52 is fixedly installed on the connecting frame 51. The locking hook 53 is rotatably fitted on the connecting frame 51. The fixed hook 52 is provided with a locking groove 521 having an opening. The locking groove 521 realizes the switching between two states of opening and closing through the rotation of the locking hook 53. A spring 54 is abutted between the fixed hook 52 and the locking hook 53, and the spring 54 always has a tendency to keep the locking groove 521 in a closed state.

[0022] The locking hook 53 is rotatably installed on the connecting frame 51 through a rotating shaft 55. The fixed hook 52 is provided with a first guiding surface 522. The locking hook 53 has a first end and a second end located on both sides of the rotating shaft 55. The first end of the locking hook 53 is provided with a second guiding surface 531. When the locking groove 521 is in a closed state, the first guiding surface 522 and the second guiding surface 531 form a guiding groove. In this embodiment, the guiding groove is in a "V" shape.

[0023] The fixed hook 52 is provided with an arc surface 520, and the locking hook 53 is provided with an arc groove 5300. The arc surface 520 and the arc groove 5300 are arranged in a fitting manner. When the locking hook 53 rotates around the axis of the rotating shaft 55, the arc surface 520 and the arc groove 5300 always keep in a fitting state. Therefore, the cooperation between the arc surface 520 and the arc groove 5300 plays a guiding role.

[0024] The connecting frame 51 is provided with an installation groove 57. The fixed hook 52 and the locking hook 53 are both arranged in the installation groove 57. The fixed hook 52 is provided with a backing plate 56. The sum of the thickness of the backing plate 56 and the fixed hook 52 is greater than the thickness of the locking hook 53, so that there is a gap between the locking hook 53 and the installation groove 57, thereby making the rotation of the locking hook 53 smoother.

[0025] The second end of the locking hook 53 is provided with a protruding pressing part 532. By manually pressing the pressing part 532, the locking hook 53 is driven to swing, so that the locking groove 521 is switched from a closed state to an open state, that is, the unlocking function. The second end of the locking hook 53 is provided with a pressing groove 530, and a plurality of convex strips 534 are arranged on the pressing groove 530. The convex strips 534 play a role in increasing the friction force, thereby preventing the fingers from slipping between the locking hook 53 during manual pressing.

[0026] The second end of the locking hook 53 is provided with an installation hole 533 for installing a pulling rope 61. By connecting the pulling rope 61 inside and outside the installation hole 533, the unlocking function can be realized by pulling the pulling rope 61.

[0027] The fixed hook 52 is provided with a first connecting groove 523, the locking hook 53 is provided with a second connecting groove 535, and the spring 54 is installed in the first connecting groove 523 and the second connecting groove 535.

[0028] The connecting frame 51 includes two connecting plates 58, a plurality of first connecting members 591 and a plurality of second connecting members 592. The first connecting members 591 are used to install the connecting plates 58 to other devices that need to install the locking device, and the second connecting members 592 are used to fixedly install the fixed hook 52 to the connecting plates 58. An installation groove 57 is formed between the two connecting plates 58. It should be noted that both the first connecting members 591 and the second connecting members 592 are bolts and nuts.

[0029] A pedal assembly 6 is movably installed on the vehicle frame 2. A pull rope 61 is provided between the pedal assembly 6 and the locking hook 53. When the pedal assembly 6 moves, the locking hook 53 is driven to move through the pull rope 61.

[0030] The second end of the locking hook 53 is provided with an installation hole 533. The pedal assembly 6 includes two pedals 62 and a rotating shaft 63. The pedals 62 are symmetrically arranged at both ends of the rotating shaft 63. The rotating shaft 63 is rotationally matched with the vehicle frame 2. Two first fixing plates 64 are provided on the rotating shaft 63. First through holes 641 are provided on the first fixing plates 64. The corresponding first through holes 641 and the installation hole 533 are connected by the pull rope 61.

[0031] The pedal 62 can swing reciprocally between a first position and a second position. When the pedal 62 is in the first position, the lock groove 521 is in a closed state. When the pedal 62 is in the second position, the lock groove 521 is in an open state at this time.

[0032] Further optimized, a second fixing plate 65 is provided on the rotating shaft 63. A tension spring 66 is connected between the second fixing plate 65 and the vehicle frame 2. The tension spring 66 always has a tendency to drive the pedal 62 to swing towards the first position.

[0033] The second fixing plate 65 is provided with a second through hole 651. One end of the tension spring 66 is installed in the second through hole 651.

[0034] When the mounting base 3 needs to be installed on the vehicle frame 2: By correspondingly mating the locking rod on the mounting base 3 with the guiding grooves on the two disassembly and assembly structures, and by pressing down the mounting base 3, the locking rod is further moved downward, and then the locking rod contacts the first inclined surface and the second inclined surface. When the locking rod continues to move, the locking rod pushes the locking hook 53 to rotate around the axis of the rotating shaft 55. The locking rod pushes the locking hook 53 to rotate around the axis of the rotating shaft 55 against the elastic force of the spring 54, so that the locking groove 521 is switched from the closed state to the open state, and then the locking rod can enter the locking groove 521. When the locking rod completely enters the locking groove 521, at this time, the spring 54 pushes the locking hook 53 to reset, so that the locking groove 521 is switched from the open state to the closed state, thus realizing the function of locking the mounting base 3.

[0035] When the mounting base 3 needs to be removed: By stepping on the foot pedal 62, the rotating shaft 63 is further driven to rotate, and then the first fixing plate 64 is driven to swing, and then the pulling rope 61 is pulled to move, and then the locking hook 53 is driven to swing around the axis of the rotating shaft 55, so that the locking groove 521 is switched from the closed state to the open state, so that the locking rod can be taken out of the locking groove 521, thus realizing the function of removing the mounting base 3. After the mounting base 3 is removed, the foot pedal 62 is released. At this time, the tension spring 66 drives the second fixing plate 65 to swing, and then drives the foot pedal 62 to move from the second position to the first position, and then drives the locking hook 53 to swing reversely around the axis of the rotating shaft 55, so that the locking groove 521 is switched from the open state to the closed state, thus realizing the function of resetting the locking hook 53 and the foot pedal 62.

[0036] The elastic connection assembly includes a connecting shaft 41 and a torsion spring 42. The front arm assembly 21 and the rear arm assembly 22 are hinged through the connecting shaft 41. The torsion spring 42 is sleeved on the outer periphery of the connecting shaft 41. The torsion spring 42 has a first acting end that abuts against the front arm assembly 21 and a second acting end that abuts against the rear arm assembly 22.

[0037] Further optimized, the front arm assembly 21 includes a front arm frame 211 and a first connecting plate 212. The rear arm assembly 22 includes a rear arm frame 221 and a second connecting plate 222. The first acting end of the torsion spring 42 abuts against the first connecting plate 212, and the second end of the torsion spring 42 abuts against the second connecting plate 222.

[0038] The elastic connection component further includes an adjustment component, which is cooperatively arranged at the first acting end of the torsion spring 42. The adjustment component is used to adjust the pre-tightening force of the torsion spring 42. The adjustment component includes an adjustment plate 43 and an adjustment bolt 44. The adjustment bolt 44 is in threaded cooperation with the adjustment plate 43. The bottom of the adjustment bolt 44 is in abutting cooperation with the first connecting plate 212. By rotating the adjustment bolt 44, the adjustment plate 43 is driven to reciprocate axially along the adjustment bolt 44.

[0039] A fixing nut 45 that is in threaded cooperation with the adjustment bolt 44 is fixedly installed on the adjustment plate 43. The fixing nut 45 and the adjustment plate 43 are in welding cooperation. A locking nut 46 is in threaded cooperation with the outer periphery of the adjustment bolt 44.

[0040] A vertical plate 47 is provided on the adjustment plate 43. A positioning card slot 48 is provided on the vertical plate 47. The first acting end of the torsion spring 42 is in clamping cooperation with the positioning card slot 48, so as to prevent relative movement between the torsion spring 42 and the adjustment plate 43.

[0041] In this application, a positioning card slot 48 is provided on the adjustment plate 43. Vertical plates 47 are provided at both the front and rear ends of the adjustment plate 43, and the two vertical plates 47 and the adjustment plate 43 are integrally bent. The positioning card slot 48 runs through each vertical plate 47. The first acting end of the torsion spring 42 in this application is trapezoidally arranged. The distance between the end of the first acting end of the torsion spring 42 away from the connecting shaft 41 is smaller than the distance between the end close to the connecting shaft 41. The first acting end of the torsion spring 42 and the positioning card slot 48 are both in clamping cooperation, so as to prevent relative movement between the adjustment plate 43 and the torsion spring 42.

[0042] Further optimized, a limiting component for limiting the maximum rotation angle of the front arm assembly 21 and the rear arm assembly 22 is provided between the front arm assembly 21 and the rear arm assembly 22. The limiting component can limit the front arm assembly 21 to rotate around the connecting shaft 41 by a maximum of 25°. In addition to 25°, it can also be customized according to customer needs, such as any angle such as 20° or 30°. The limiting component includes a first limiting plate 71 and a second limiting plate 72. The first limiting plate 71 is fixedly installed on the front arm frame 211. The second limiting plate 72 is fixedly installed on the rear arm frame 221. A first protrusion 711 is provided on the first limiting plate 71. The first protrusion 711 is in limiting cooperation with the upper surface of the rear arm frame 221. A second protrusion 721 is provided on the second limiting plate 72. The second protrusion 721 is in limiting cooperation with the upper surface of the front arm frame 211. When the obstacle removal tool 1 encounters an obstacle, the front arm assembly 21 is lifted to make the first protrusion 711 contact the upper surface of the rear arm frame 221, limiting the maximum torsion angle.

[0043] The first limiting plate 71 and the second limiting plate 72 are provided with connection holes for the connection shaft 41 to pass through.

[0044] During specific operation: When the obstacle removal tool 1 encounters an obstacle during operation (such as shoveling snow, shoveling garbage, etc.), the obstacle removal tool 1 will be lifted by the obstacle. At this time, the obstacle removal tool 1 drives the front arm frame 211 to swing upward, thereby twisting the torsion spring 42. And when the obstacle is crossed, the torsion spring 42 resets, thereby driving the obstacle removal tool 1 and the front arm frame 211 to reset.

[0045] During specific installation: By sleeving the torsion spring 42 on the outer periphery of the connection shaft 41 and inserting the connection shaft 41 into the connection hole, the second acting end of the torsion spring 42 is in abutting cooperation with the second connecting plate 222, and the first end of the torsion spring 42 is snap-fitted into the card slot of the adjusting plate 43, so that the lower end of the adjusting plate 43 is in abutting cooperation with the upper surface of the first connecting plate 212. By installing the adjusting bolt 44 into the fixing nut 45 and the bottom of the adjusting bolt 44 is in abutting cooperation with the first connecting plate 212, by rotating the adjusting bolt 44, the adjusting plate 43 moves upward along the axis of the adjusting bolt 44, thereby jacking up the first acting end of the torsion spring 42, thereby playing a pre-tightening role. When pre-tightened to the appropriate position, by rotating the locking nut 46, the locking nut 46 moves downward, so that the locking nut 46 contacts the fixing nut 45, thereby preventing the adjusting bolt 44 from loosening.
