Description

Technical Field

[0001] This invention belongs to the field of all-terrain vehicle technology, specifically a steering device for a large four-wheeled amphibious all-terrain vehicle. Background Technology

[0002] A large four-wheeled amphibious all-terrain vehicle is a model based on a four-wheeled all-terrain vehicle structure and equipped with water-floating capabilities. The steering system is a series of mechanical structures used to receive the driver's steering intentions and drive the wheels to deflect, thereby changing the direction of travel.

[0003] Patent CN218141744U discloses a steering structure for an agricultural all-terrain vehicle, including a steering gear body, a fixed cylinder, and an operating panel. A steering wheel is rotatably connected to one side of the steering gear body. A groove is formed on the front of the fixed cylinder, and a slider is slidably connected inside the groove. A connecting plate is fixedly connected to one side of the slider, and a fixed post is fixedly connected to the top of the connecting plate. A slot is formed on the outer wall of the fixed post, and a fixing bolt is rotatably connected to the front of the fixed cylinder. This steering structure for agricultural all-terrain vehicles facilitates the adjustment of the length of the fixed post, making the device easier to operate, reducing property damage, and improving the ease of use of the device. It saves considerable time and effort, avoiding the time-consuming and laborious process of adjusting the height of the fixed post, which reduces the device's usability and makes it inconvenient to use.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: Although the wheels can be steered, they may come into contact with metal fragments on the road surface while the vehicle is in motion. If these fragments are sharp, they can easily puncture the wheels, thus affecting their lifespan. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a steering device for a large four-wheeled amphibious all-terrain vehicle.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a steering device for a large four-wheeled amphibious all-terrain vehicle, including a chassis, with a connecting rod rotatably arranged at each of the four corners of the upper surface of the chassis, a protective shell fixedly connected to one end of the connecting rod, and a wheel rotatably arranged inside the protective shell; It also includes transmission components; The transmission assembly includes a rack slidably connected to both sides of the upper end face of the chassis, and a second connecting rod is rotatably provided at both ends of the rack, with one end of the second connecting rod rotatably connected to one end of the first connecting rod. It also includes protective components; The protective component includes a support block fixedly connected to the middle of one side of the protective shell, a rotating plate rotatably disposed on one side of the support block, and an electromagnet fixedly connected to one end of the rotating plate.

[0007] Preferably, the upper end of the chassis is provided with rotating shafts on both the front and rear sides, and a gear is fixedly sleeved on the lower end of the rotating shaft, the gear meshing with the rack.

[0008] Preferably, a sprocket is fixedly sleeved on the upper end of the rotating shaft, and two sprockets are meshed together to connect a chain.

[0009] Preferably, a control lever is fixedly connected to one end of the front rotating shaft, and a handle is fixedly connected to the upper end of the control lever.

[0010] Preferably, a motor is fixedly connected to one side of the outer wall of the protective shell, and the output end of the motor is fixedly connected to one end of the rotating plate.

[0011] Preferably, it also includes an impurity removal component; The impurity removal component includes a fixed plate fixedly connected to one side of the outer wall of the protective shell. A flip plate is rotatably provided at one end of the fixed plate. Two sliding columns are slidably connected to the flip plate, and a scraper is fixedly connected to one end of each sliding column.

[0012] Preferably, a second motor is fixedly connected to one end of the fixed plate, and the output end of the second motor is fixedly connected to one end of the flip plate.

[0013] Preferably, a spring is fitted at one end of the sliding column, one end of the spring is fixedly connected to the scraper, and the other end is fixedly connected to the flipping plate.

[0014] The beneficial effects of this invention are as follows: 1. The present invention discloses a steering device for a large four-wheeled amphibious all-terrain vehicle. Utilizing a transmission assembly, when the driver of the all-terrain vehicle rotates the handle to turn the control lever, thereby causing the shaft on one side to rotate. Under the transmission of the sprocket and chain, the gears on both sides rotate simultaneously, driving the rack to slide on the chassis. The rack then drives the second connecting rod to rotate, which in turn drives the first connecting rod to rotate, thereby causing the protective shell to rotate. This achieves simultaneous steering of all four wheels. During the entire steering process, multiple structures work together, resulting in sensitive braking, fast response, simple and safe structure, and a low failure rate.

[0015] 2. The steering device for a large four-wheeled amphibious all-terrain vehicle described in this invention allows for the attraction of metal fragments from the road surface to the wheels when the vehicle is traveling on the road. The fragments are attracted by an electromagnet, preventing them from contacting the wheels and thus avoiding punctures. Furthermore, a debris removal component is used. Once a certain amount of metal fragments accumulates on the electromagnet surface, a rotating plate rotates, moving the electromagnet from the front to the rear of the wheel. Then, the electromagnet is de-energized, causing the metal fragments to fall onto the path the wheel has already traveled. The electromagnet is then reset, and the two rear electromagnets re-attract the metal fragments that have fallen from the front electromagnet surface. The two rear electromagnets are then rotated to the rear of the wheel, and the electromagnet is de-energized. This prevents metal fragments from falling from the electromagnet surface from contacting the wheels again. This achieves both the cleaning of metal fragments from the electromagnet surface and the maintenance of its continuous attraction capacity, while also preventing metal fragments from puncturing the tires again. Furthermore, when the electromagnet rotates, its surface comes into contact with the end of the scraper. The scraper, under the action of the sliding column and spring, remains in close contact with the electromagnet surface, thus removing impurities adhering to the electromagnet surface. The scraped-off impurities accumulate on the scraper surface, which can then be dislodged by rotating the flip plate. This prevents impurities from accumulating on the scraper surface and adhering back to it when the electromagnet comes into contact with the scraper again, ensuring a continuous cleaning effect on the electromagnet surface.

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please refer to Figures 1-7 The present invention provides a technical solution: a steering device for a large four-wheeled amphibious all-terrain vehicle, including a chassis 1, with connecting rods 9 rotatably arranged at the four corners of the upper surface of the chassis 1, a protective shell 3 fixedly connected to one end of the connecting rods 9, and wheels 4 rotatably arranged inside the protective shell 3. It also includes transmission components; The transmission assembly includes a rack 11 that is slidably connected to both sides of the upper end face of the chassis 1. Both ends of the rack 11 are rotatably provided with connecting rods 2 10, and one end of connecting rod 2 10 is rotatably connected to one end of connecting rod 1 9. It also includes protective components; The protective component includes a support block 20 fixedly connected to the middle of one side of the protective shell 3, a rotating plate 7 rotatably disposed on one side of the support block 20, and an electromagnet 5 fixedly connected to one end of the rotating plate 7.

[0021] In this embodiment, as Figure 2 , Figure 4 As shown, a rotating shaft 21 is rotatably mounted on both the front and rear sides of the upper end of the chassis 1. A gear 14 is fixedly mounted on the lower end of the rotating shaft 21, and the gear 14 meshes with the rack 11.

[0022] A sprocket 13 is fixedly sleeved on the upper end of the shaft 21, and the two sprockets 13 are meshed together with the chain 12.

[0023] A control lever 6 is fixedly connected to one end of the front rotating shaft 21, and a handle 2 is fixedly connected to the upper end of the control lever 6.

[0024] Specifically, the chassis 1 is mounted on the main body of the all-terrain vehicle, and the wheels 4 are driven by the transmission structure. When the driver is driving the all-terrain vehicle, the control lever 6 can be rotated by turning the handle 2, which causes the shaft 21 on one side to rotate. Under the transmission of the sprocket 13 and the chain 12, the gears 14 on both sides rotate simultaneously, and drive the rack 11 to slide on the chassis 1. The rack 11 will drive the connecting rod 2 10 to rotate, and the connecting rod 2 10 will drive the connecting rod 1 9 to rotate, thereby causing the protective shell 3 to rotate, thus realizing the simultaneous steering of the four wheels 4. During the entire steering process, multiple structures work together, the braking is sensitive, the response speed is fast, and the structure is simple, safe, and has a low failure rate.

[0025] In this embodiment, as Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, a motor 8 is fixedly connected to one side of the outer wall of the protective shell 3, and the output end of the motor 8 is fixedly connected to one end of the rotating plate 7.

[0026] It also includes an impurity removal component; The impurity removal component includes a fixed plate 15 fixedly connected to one side of the outer wall of the protective shell 3. A flip plate 22 is rotatably provided at one end of the fixed plate 15. Two sliding columns 18 are slidably connected on the flip plate 22. A scraper 17 is fixedly connected to one end of each sliding column 18.

[0027] One end of the fixed plate 15 is fixedly connected to the second motor 16, and the output end of the second motor 16 is fixedly connected to one end of the flip plate 22.

[0028] A spring 19 is fitted at one end of the sliding column 18. One end of the spring 19 is fixedly connected to the scraper 17, and the other end is fixedly connected to the flipping plate 22.

[0029] Specifically, in the existing technology, although the wheel 4 can be steered, it may come into contact with metal fragments on the road surface during vehicle operation. If these fragments are sharp, they can easily puncture the wheel 4, thereby affecting the service life of the wheel 4.

[0030] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: When the vehicle is driving on the road, the electromagnet 5 is energized. When a metal fragment on the road is about to come into contact with the wheel 4, the metal fragment will be attracted by the electromagnet 5, so that the metal fragment will not come into contact with the wheel 4, thus avoiding the situation where the fragment punctures the wheel 4.

[0031] While the above methods prevent metal fragments from puncturing wheel 4, once a certain number of metal fragments accumulate on the surface of electromagnet 5, the large area covered by the fragments will affect the electromagnet's ability to attract the fragments. Furthermore, if the electromagnet is de-energized to allow the metal fragments to fall to the ground, they will simply return to the wheel's path, still posing a risk of puncturing wheel 4. Therefore, to solve this problem, whenever a certain amount of metal fragments accumulate on the surface of electromagnet 5, motor 8 drives rotating plate 7 to rotate, moving electromagnet 5 from the front side of wheel 4 to the rear side. Then, the power to electromagnet 5 is stopped, and the metal fragments will fall onto the path that wheel 4 has already traveled. Then, electromagnet 5 is driven to reset, and the two rear electromagnets 5 will again attract the metal fragments that have fallen from the surface of the front electromagnet 5 to the ground. Then, the two rear electromagnets 5 are driven to rotate to the rear side of wheel 4 again, and then the power to electromagnet 5 is stopped. This prevents the metal fragments that have fallen from the surface of electromagnet 5 from contacting wheel 4 again. This not only cleans the metal fragments on the surface of electromagnet 5 and ensures the continuous attraction capacity of electromagnet 5, but also prevents the metal fragments that have fallen to the road from puncturing the tire again.

[0032] Furthermore, since wheel 4 travels on the road, dust, particles, and other impurities from the road surface easily adhere to the surface of electromagnet 5, thus obscuring its surface and affecting its subsequent adsorption effect. Therefore, to avoid this problem, when electromagnet 5 rotates, its surface contacts the end of scraper 17. Scraper 17, under the action of sliding column 18 and spring 19, maintains a tight seal with the surface of electromagnet 5, allowing the scraper 17 to remove impurities adhering to its surface. The scraped-off impurities accumulate on the surface of scraper 17, which can then be dislodged by rotating flip plate 22 via motor 16. This prevents impurities from accumulating on the scraper 17 and re-adhering to it when electromagnet 5 contacts scraper 17 later, ensuring a continuous cleaning effect on the surface of electromagnet 5.

[0033] Working principle: The chassis 1 is mounted on the body of the all-terrain vehicle, and the wheels 4 are driven by the transmission structure. When the driver is driving the all-terrain vehicle, the control lever 6 can be rotated by turning the handle 2, which will cause the shaft 21 on one side to rotate. Under the transmission of the sprocket 13 and the chain 12, the gears 14 on both sides will rotate simultaneously, and drive the rack 11 to slide on the chassis 1. The rack 11 will drive the second connecting rod 10 to rotate, and the second connecting rod 10 will drive the first connecting rod 9 to rotate, thereby causing the protective shell 3 to rotate, thus realizing the simultaneous steering of the four wheels 4. During the entire steering process, multiple structures work together, the braking is sensitive, the response speed is fast, and the structure is simple, safe, and has a low failure rate.

[0034] When the vehicle is driving on the road, the electromagnet 5 is energized. When a metal fragment on the road is about to come into contact with the wheel 4, the metal fragment will be attracted by the electromagnet 5, so that the metal fragment will not come into contact with the wheel 4, thus avoiding the situation where the fragment punctures the wheel 4.

[0035] While the above methods prevent metal fragments from puncturing wheel 4, once a certain number of metal fragments accumulate on the surface of electromagnet 5, the large area covered by the fragments will affect the electromagnet's ability to attract the fragments. Furthermore, if the electromagnet is de-energized to allow the metal fragments to fall to the ground, they will simply return to the wheel's path, still posing a risk of puncturing wheel 4. Therefore, to solve this problem, whenever a certain amount of metal fragments accumulate on the surface of electromagnet 5, motor 8 drives rotating plate 7 to rotate, moving electromagnet 5 from the front side of wheel 4 to the rear side. Then, the power to electromagnet 5 is stopped, and the metal fragments will fall onto the path that wheel 4 has already traveled. Then, electromagnet 5 is driven to reset, and the two rear electromagnets 5 will again attract the metal fragments that have fallen from the surface of the front electromagnet 5 to the ground. Then, the two rear electromagnets 5 are driven to rotate to the rear side of wheel 4 again, and then the power to electromagnet 5 is stopped. This prevents the metal fragments that have fallen from the surface of electromagnet 5 from contacting wheel 4 again. This not only cleans the metal fragments on the surface of electromagnet 5 and ensures the continuous attraction capacity of electromagnet 5, but also prevents the metal fragments that have fallen to the road from puncturing the tire again.

[0036] Furthermore, since wheel 4 travels on the road, dust, particles, and other impurities from the road surface easily adhere to the surface of electromagnet 5, thus obscuring its surface and affecting its subsequent adsorption effect. Therefore, to avoid this problem, when electromagnet 5 rotates, its surface contacts the end of scraper 17. Scraper 17, under the action of sliding column 18 and spring 19, maintains a tight seal with the surface of electromagnet 5, allowing the scraper 17 to remove impurities adhering to its surface. The scraped-off impurities accumulate on the surface of scraper 17, which can then be dislodged by rotating flip plate 22 via motor 16. This prevents impurities from accumulating on the scraper 17 and re-adhering to it when electromagnet 5 contacts scraper 17 later, ensuring a continuous cleaning effect on the surface of electromagnet 5.
