Description

Technical Field

[0001] The invention relates to a wave-breaking plate mounting structure of an all-terrain vehicle. Background Art

[0002] When performing tasks, tracked all-terrain vehicles should be able to travel quickly on land and sea, and achieve high-frequency free conversion between the two.

[0003] Therefore, wave-breaking equipment should have the function of no need for disassembly and assembly, and can be quickly retracted and deployed. Currently, the commonly used wave-breaking equipment is roughly divided into two types: flat-plate type and pointed-head type. Among them, the advantage of flat-plate wave-breaking equipment is that it reduces the depth of the entire vehicle entering the water and prevents the front of the vehicle from "diving"; the pointed-head type has the advantages of flat-plate wave-breaking equipment, because its shape also has a diversion function, which can reduce wave resistance and increase sea travel speed. However, the above two types of wave-breaking equipment are large in size, fixed in structure, and inconvenient to disassemble. During land travel, they will have a great impact on the vehicle's field of vision, thereby directly reducing the maneuverability of the crawler all-terrain vehicle. Summary of the invention

[0004] The purpose of the present invention is: to address the above problems of existing wave-breaking equipment, the present invention will provide a foldable wave-breaking equipment, which has a small volume, light weight, and does not require disassembly after being folded. The all-terrain vehicle can achieve rapid and high-frequency conversion between land and sea travel.

[0005] The technical solution of the present invention:

[0006] A foldable wave-breaking equipment for a tracked all-terrain vehicle comprises a mounting frame 1 on a vehicle body, wherein two mounting frames 1 are located on the left and right sides of the vehicle head, the tail ends of a wave-breaking plate 12 are hingedly mounted on the two mounting frames 1, and the front end of the wave-breaking plate 12 is hingedly connected to an upper wave-breaking plate 20; a swivel arm 7 is also hingedly mounted on the mounting frame 1, and the rear end of the swivel arm 7 is hingedly connected to a hydraulic rod of an oil cylinder 5, and the cylinder body of the oil cylinder 5 is hingedly mounted on the vehicle head; the front end of the swivel arm and the rear end of a connecting rod 11 are hingedly connected through a sliding pin 10, and the sliding pin 10 is installed in slideways on both sides of the wave-breaking plate 12; the front end of the connecting rod 11 and the rear end of a rocker arm 19 are hingedly connected through an upper sliding pin 18, and the upper sliding pin 18 is installed in slideways on both sides of the upper wave-breaking plate 20, and the end of the rocker arm 19 is hingedly mounted on the front end of the wave-breaking plate 12.

[0007] A lower wave-breaking plate 15 is provided, the upper end of which is hinged on the lower surface of the wave-breaking plate 12, and lower sliding pins 14 are fixed on both sides of the lower edge of the front of the vehicle, and the lower sliding pins 14 cooperate with the slideways on both sides of the lower wave-breaking plate 15.

[0008] The swing arm 7 is composed of two guard plates and three pins, and the three pins are not in the same straight line. The pin at the rear end is used as the hinge point for hinge connection with the cylinder 5, the pin in the middle is used as the hinge point for hinge connection with the mounting frame 1, and the pin at the front end is used as the hinge point for hinge connection with the connecting rod 11. At the same time, the pin at the front end has a protruding structure on the inner side as a sliding pin 10.

[0009] The tail end of the wave-breaking plate 12 is hingedly mounted on the lower end of the mounting frame 1 , and the rotating arm 7 is hingedly mounted on the upper end of the mounting frame 1 .

[0010] The hinge point between the wave-breaking plate 12 and the mounting frame 1 , the hinge point between the wave-breaking plate 12 and the swing rod 19 , and the hinge point between the wave-breaking plate 12 and the upper wave-breaking plate 20 are not in the same straight line.

[0011] A limit pin is installed on the swing rod 19.

[0012] When the oil cylinder 5 is extended to the initial state, the wave-breaking board 12 and the upper wave-breaking board 20 are folded and drooped; as the oil cylinder 5 contracts, the wave-breaking board 12 flips upward, and at the same time, the angle between the upper wave-breaking board 20 and the wave-breaking board 12 increases.

[0013] The cylinder body of the oil cylinder 5 is hingedly mounted on the oil cylinder base 2, and the oil cylinder base 2 is mounted on the front of the vehicle.

[0014] Beneficial effects of the present invention:

[0015] The present invention realizes the unfolding and folding of the wave-breaking board by using one oil cylinder. When traveling on land, the wave-breaking board can be folded without affecting the field of vision. When wading, the wave-breaking board can be unfolded to reduce the water entry depth of the whole vehicle and prevent the spray from splashing the front of the vehicle.

[0020] Embodiment 1:

[0021] A foldable wave-breaking equipment for a tracked all-terrain vehicle comprises a mounting frame 1 on a vehicle body, wherein two mounting frames 1 are located on the left and right sides of the vehicle head, the tail end of a wave-breaking plate 12 is hinged on the two mounting frames 1 (the hinge point is a pin 13), and the front end of the wave-breaking plate 12 is hinged to an upper wave-breaking plate 20 (the hinge point is a pin 17); a swivel arm 7 (the hinge point is a pin 9) is also hinged on the mounting frame 1, the rear end of the swivel arm 7 is hinged to a hydraulic rod of an oil cylinder 5 (the hinge point is a pin 8), and the cylinder body of the oil cylinder 5 is hinged on the vehicle head (the hinge point is a pin 6); the front end of the swivel arm and the rear end of a connecting rod 11 are hinged through a sliding pin 10, and the sliding pin 10 is installed in slideways on both sides of the wave-breaking plate 12; the front end of the connecting rod 11 and the rear end of a rocker arm 19 are hinged through an upper sliding pin 18, and the upper sliding pin 18 is installed in slideways on both sides of the upper wave-breaking plate 20, and the end of the rocker arm 19 is hinged to the front end of the wave-breaking plate 12 (the hinge point is a shaft pin 21).

[0025] A limit pin is installed on the rocker arm 19. When the rocker arm 19 rotates relative to the connecting rod 11, it drives the upper wave-breaking plate 20 to unfold. When the angle between the wave-breaking plate 20 and the wave-breaking plate 12 is unfolded to 180°, the rocker arm 19 and the connecting rod 11 almost overlap. At this time, the limit pin contacts the connecting rod 11 to prevent the rocker arm 19 from continuing to rotate.

[0026] When the oil cylinder 5 is extended to the initial state, the wave-breaking board 12 and the upper wave-breaking board 20 are folded and drooped; as the oil cylinder 5 contracts, the wave-breaking board 12 flips upward, and at the same time, the angle between the upper wave-breaking board 20 and the wave-breaking board 12 increases.

The length between the sliding pin 10 and the pin 13 is variable, and the lengths of the other two remain unchanged.
