[0002] Amphibious vehicles driven by water jet propulsion navigate on water by adjusting the angle of the water jets on a rudder with nozzles. However, reversing on water requires a reversing mechanism. Existing reversing mechanisms for amphibious vehicles have drawbacks such as large installation space and complex connections of moving parts. Furthermore, existing reversing mechanisms often use triangular plates to form a linkage mechanism and a dual-cylinder structure for drive, resulting in complex connection and locking structures and high costs.
[0003] For example, announcement number CN113968332A was published on January 25, 2022. The aforementioned disclosed compact reversing device for a marine waterjet propulsion system includes the following structure: a waterjet propulsion system, a reversing hydraulic cylinder, a flexible sealing device, and a reversing bucket. The waterjet propulsion system is fixed to the stern steel plate, and the water jet nozzle of the waterjet propulsion system is located on the outer side of the stern steel plate. The reversing bucket is fixed at the water jet nozzle, and the reversing bucket rotates with the water jet nozzle of the waterjet propulsion system via swing arms on both sides. The top of each swing arm on both sides of the reversing bucket is connected to the telescopic rod of a reversing hydraulic cylinder. The front end of the cylinder seat of the reversing hydraulic cylinder is rotatably fixed to the stern steel plate via a flexible sealing device. In use, the reversing head of the aforementioned disclosed reversing bucket is connected to the hydraulic cylinder via triangular swing arms. The entire reversing head's drive structure is complex, has high manufacturing costs, and poor practicality. Summary of the Invention

Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0019] like Figure 1 As shown, the amphibious vehicle reversing bucket moving device includes a reversing bucket 2 mounted on the vehicle body 1. The reversing bucket 2 is connected to the vehicle body 1 via a linkage assembly. The vehicle body 1 is equipped with a drive assembly for moving the reversing bucket 2. Specifically, the reversing bucket 2 is installed at the rear of the vehicle body 1. The reversing bucket 2 has an arc surface. The arc surface of the reversing bucket changes the water spray direction to a downward angle, propelling the amphibious vehicle in reverse. The structure is simple, occupies little space, and has minimal loss of buoyancy.
[0020] When the position of the reverse bucket 2 needs to be moved, the drive component works to make the reverse bucket 2 move up and down under the support of the linkage assembly, thereby realizing the adjustment of the position of the reverse bucket 2. The position of the reverse bucket 2 can be easily adjusted through the linkage assembly. The overall structure is simple to bear force, enhances the impact resistance of the reverse bucket, and is more practical.
[0021] Specifically, the connecting assembly includes a first connecting rod 8, a first connecting seat 9, a second connecting rod 12, and a second connecting seat 13. The first connecting rod 8 and the second connecting rod 12 are respectively disposed at both ends of the reverse bucket 2. One end of the first connecting rod 8 is hinged to the reverse bucket 2, and the other end of the first connecting rod 8 is hinged to the first connecting seat 9. The first connecting seat 9 is connected to the vehicle body 1. One end of the second connecting rod 12 is hinged to the reverse bucket 2, and the other end of the second connecting rod 12 is hinged to the second connecting seat 13. The second connecting seat 9 is connected to the vehicle body 1. The driving assembly is connected to the first connecting rod 8. When the driving assembly works, the first connecting rod 8 rotates on the first connecting seat 9, and the second connecting rod 12 rotates under the support of the second connecting seat 13. As a result, the reverse bucket 2 moves under the drive of the first connecting rod 8 and the second connecting rod 12, thereby realizing convenient position adjustment of the reverse bucket 2. In this embodiment, there are two first connecting rods 8 and two second connecting rods 12. The two first connecting rods 8 are respectively disposed at the upper end of the reverse bucket 2, and the two second connecting rods 12 are respectively disposed at the lower end of the reverse bucket 2.
[0022] The drive assembly includes a hydraulic cylinder 4 connected to the vehicle body 1. The piston of the hydraulic cylinder 4 is hinged to the first connecting rod 8. When the hydraulic cylinder 4 is working, the piston of the hydraulic cylinder 4 moves and drives the first connecting rod 8 to rotate, thereby driving the reverse bucket 2. In this embodiment, there are two hydraulic cylinders 4, which are parallel to the two first connecting rods 8 respectively, so that the two hydraulic cylinders 4 can stably drive the reverse bucket 2.
[0023] The vehicle body 1 is provided with a mounting bracket 3, a fixed seat 6 is provided on the mounting bracket 3, and a side seat 5 is provided on the fixed seat 6. The side seat 5 is hinged to the cylinder body of the hydraulic cylinder 4 through the first pin 7. The mounting bracket 3 and the fixed seat 6 are used to achieve stable installation of the hydraulic cylinder 4 on the vehicle body. Specifically, there are two mounting brackets 3, each mounting bracket 3 is provided with a fixed seat 6, and two side seats 5 are welded on each fixed seat 6. The mounting bracket 3 is welded to the vehicle body 1, the mounting bracket 3 is connected to the fixed seat 6 by bolts, the fixed seat 6 is welded to the side seats 5, and the side seats 5 are provided with through holes for installing the first pin 7.
[0024] The first connecting seat 9 is connected to the vehicle body 1 by bolts, thereby realizing convenient disassembly and assembly of the first connecting seat 9. The first connecting seat 9 is provided with a first mounting plate 11. The first mounting plate 11 is hinged to the first connecting rod 8 through the second pin 10. The first connecting rod 8 is stably installed on the vehicle body 1 through the first mounting plate 11 and the second pin 10. Specifically, the first connecting seat 9 is welded to two first mounting plates 11. The end of the first connecting rod 8 is located between the two first mounting plates 11, and the first connecting rod 8 and the first mounting plate 11 are provided with pin holes for installing the second pin 10.
[0025] The second connecting seat 13 is provided with a second mounting plate 14. The second mounting plate 14 is connected to the second connecting rod 12 through a third pin 15. The second connecting rod 12 is stably installed on the vehicle body 1 through the second mounting plate 14 and the third pin 15. Specifically, two second mounting plates 14 are welded on the second connecting seat 13. The end of the second connecting rod 12 is located between the two second mounting plates 14, and the second connecting rod 12 and the second mounting plate 14 are provided with pin holes for installing the third pin 15.
[0026] The second connecting rod 12 is provided with a positioning pin 16, and the second mounting plate 14 is provided with a positioning groove 17 that cooperates with the positioning pin 16. When the reversing bucket 2 rotates to the designated position, the positioning pin 16 on the second connecting rod 12 engages in the positioning groove 17 of the second mounting plate 14, thereby positioning and limiting the second connecting rod 12 and the entire reversing bucket 2, and at the same time providing support for the second connecting rod 12 and the reversing bucket 2, and also enhancing the water flow impact resistance of the reversing bucket 2. Specifically, the positioning pin 6 is welded to the second connecting rod 12.
[0027] The first link 8 is provided with a reinforcing rib 18. The strength of the first link 8 is increased by the setting of the reinforcing rib 18, thereby increasing the strength and service life of the entire moving device and making it more practical.
[0028] In summary, when the reverse bucket 2 needs to be positioned, the two hydraulic cylinders 4 operate. The pistons of the hydraulic cylinders 4 move, causing the two first connecting rods 8 to rotate. Consequently, the second connecting rod 12 rotates under the support of the second connecting seat 13. Then, the reverse bucket 2 moves under the influence of the first connecting rods 8 and the second connecting rod 12. When the reverse bucket 2 rotates to the designated position, the positioning pin 16 on the second connecting rod 12 engages in the positioning groove 17 of the second mounting plate 14, thereby positioning and limiting the second connecting rod 12 and the entire reverse bucket 2, while also providing support for the second connecting rod 12 and the reverse bucket 2.
[0029] The reversing mechanism is integrated with the water jet propulsion device, which is simple in structure, reduces costs, occupies little space, and is equipped with a positioning structure, eliminating the need for a locking structure. It is lightweight while enhancing impact resistance.
[0030] When reversing on water, the reversing bucket assembly is propelled by a hydraulic cylinder. When it is inverted and placed in front of the water jet propulsion device's rudder nozzle, the first connecting rod 8 and the second connecting rod 12 form a parallel support structure. This simple structure reduces stress and enhances the reversing bucket's impact resistance. The curved surface of the reversing bucket redirects the water jet direction downwards, propelling the amphibious vehicle backwards. The structure is simple, occupies little space, and minimizes buoyancy loss.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
