Description

Technical Field

[0001] This utility model relates to a vehicle suspension device, and more particularly to a terrain-adaptive suspension device for a vehicle snowplow, belonging to the field of snowplow technology. Background Technology

[0002] During the cold winter, frequent snowfalls blanket the earth in white, but also pose serious challenges to road traffic. Accumulated snow severely impacts traffic safety and flow, making daily travel difficult, significantly reducing the efficiency of freight transport, and disrupting the supply and distribution of various goods.

[0003] Vehicle snowplows are a common type of snow removal equipment. However, when faced with narrow roads, existing vehicle snowplows cannot adjust themselves to the most suitable angle. This makes it difficult to quickly and accurately remove the mixture of snow and rainwater from the road to one side, thus failing to clear the road in the shortest time and restore traffic flow.

[0004] Therefore, there is an urgent need to improve the terrain-adaptive suspension system for vehicle snowplows in order to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a terrain-adaptive suspension device for a vehicle snowplow. Multiple hydraulic rods work together to adjust the angle of the adjustment plate. When the angle of the adjustment plate changes due to the action of the hydraulic rods, the fixed frame moves synchronously. After the position of the fixed frame changes, the rotating frame can rotate around the connection point with the fixed frame to further adjust the angle of the rotating frame. The adjustment frame drives the snowplow to move synchronously. Through this linkage mechanism, the horizontal angle of the snowplow can be adjusted to the maximum extent, so that the snowplow can adapt to different application scenarios.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A terrain-adaptive suspension device for a vehicle snowplow includes a vehicle body connecting frame, an angle adjustment structure one, and an angle adjustment structure two. The angle adjustment structure one includes multiple hydraulic rods one and an adjustment plate. One end of each of the multiple hydraulic rods one is fixedly connected to the vehicle body connecting frame, and the other end of each of the multiple hydraulic rods one is hinged to one side of the adjustment plate. The multiple hydraulic rods one are evenly distributed at the upper and lower ends of the vehicle body connecting frame.

[0008] The second angle adjustment structure includes a fixed frame and a rotating frame. One side of the fixed frame is fixedly connected to one side of the adjustment plate, and one end of the fixed frame is rotatably connected to one end of the rotating frame. A snowplow is rotatably connected to the side of the rotating frame away from the fixed frame.

[0009] Preferably, the fixed frame is rotatably connected to two hydraulic rods on both sides of one end near the rotating frame, and the other end of the hydraulic rods is rotatably connected to one side of the rotating frame.

[0010] Preferably, a support plate is fixedly connected to the upper end of the side of the adjusting plate away from the first hydraulic rod, and a third hydraulic rod is hinged to the lower bottom surface of the support plate, with the other end of the third hydraulic rod corresponding to the snowplow.

[0011] Preferably, the snowplow is fixedly connected to a connecting seat on the side near the hydraulic rod three, and a rotating ball is rotatably connected inside the connecting seat. The outer wall of the rotating ball is fixedly connected to one end of the hydraulic rod three.

[0012] Preferably, the snowplow has multiple sliding rods slidably connected inside both sides, and one end of each sliding rod is fixedly connected to an extension plate.

[0013] Preferably, a hydraulic telescopic rod is fixedly connected to the side of the snowplow near the extension plate, and the output end of the hydraulic telescopic rod is fixedly connected to the extension plate.

[0014] Preferably, the vehicle body connecting frame has multiple lifting rods hinged to the side away from the angle adjustment structure.

[0015] This utility model has at least the following beneficial effects:

[0016] 1. Multiple hydraulic rods work together to adjust the angle of the adjusting plate. When the angle of the adjusting plate changes due to the action of the hydraulic rods, the fixed frame moves synchronously. After the position of the fixed frame changes, the rotating frame can rotate around the connection point with the fixed frame to further adjust the angle of the rotating frame. The adjusting frame drives the snowplow to move synchronously. Through this linkage mechanism, the horizontal angle of the snowplow can be adjusted to the maximum extent, so that the snowplow can adapt to different application scenarios.

[0017] 2. Multiple sliding rods are slidably connected inside both sides of the snowplow. Their function is to connect the snowplow to the extension plate and guide the movement of the extension plate. The extension plate is fixed to one end of the sliding rod and connected to the snowplow through the sliding rod. Under the control of the snowplow, it can extend and retract. When encountering a wider road surface or an area with a large amount of snow, the extension plate extends, increasing the effective working width of the snowplow and thus improving snow removal efficiency. When not needed, the extension plate can retract into the snowplow, facilitating the equipment's movement or storage in narrow spaces. In addition, the sliding rods can withstand a certain amount of external force when the extension plate is in operation, ensuring the stability of the entire structure. Attached Figure Description

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] like Figures 1-4As shown in the figure, this embodiment provides a terrain-adaptive suspension device for a vehicle-mounted snowplow, including a vehicle body connecting frame 1, an angle adjustment structure 1 2, and an angle adjustment structure 2 3. The vehicle body connecting frame 1 serves as the basic connecting component of the entire device, connecting the vehicle. The angle adjustment structure 1 2 includes multiple hydraulic rods 4 and an adjustment plate 5. One end of each hydraulic rod 4 is fixedly connected to the vehicle body connecting frame 1, and the other end of each hydraulic rod 4 is hinged to one side of the adjustment plate 5. The hydraulic rods 4 are evenly distributed at the upper and lower ends of the vehicle body connecting frame 1, and there are six hydraulic rods 4 in total. The upper part of the vehicle body connecting frame 1... Three hydraulic rods 4 are distributed at the end, with one of them located on the central axis of the body connecting frame 1 and the other two symmetrically distributed on both sides of the central axis of the body connecting frame 1. The hydraulic rod located on the central axis of the body connecting frame 1 plays a key positioning and reference role. The symmetrical distribution of hydraulic rods 4 ensures that the adjusting plate 5 is subjected to uniform force during angle adjustment. When the hydraulic rods 4 extend or retract, the adjusting plate 5 will not twist or shake due to uneven force. The six hydraulic rods 4 work together, and the angle of the adjusting plate 5 can be adjusted by precisely controlling the extension and retraction of each hydraulic rod.

[0026] Angle adjustment structure 2 (3) includes a fixed frame 6 and a rotating frame 7. One side of the fixed frame 6 is fixedly connected to one side of the adjusting plate 5, and one end of the fixed frame 6 is rotatably connected to one end of the rotating frame 7. A snowplow 8 is rotatably connected to the side of the rotating frame 7 away from the fixed frame 6. The fixed frame 6 is fixed to one side of the adjusting plate 5, serving to connect and support the rotating frame 7. One end of the rotating frame 7 is rotatably connected to the fixed frame 6, and the other end is connected to the snowplow 8. It can rotate around the connection point with the fixed frame 6, thereby driving the snowplow 8 to adjust its angle in the horizontal direction. The snowplow 8 is the component that directly performs the snow removal task. Through its rotatable connection with the rotating frame 7, under the combined action of angle adjustment structure 1 (2) and angle adjustment structure 2 (3), it can adjust its angle in both vertical and horizontal directions to better conform to the road surface and adapt to different scenarios, thereby improving snow removal efficiency and effectiveness.

[0027] Furthermore, such as Figures 1-4 As shown, hydraulic rods 21 are rotatably connected to both sides of the fixed frame 6 near the rotating frame 7. The other end of the hydraulic rods 21 is rotatably connected to one side of the rotating frame 7. The hydraulic rods 21 serve as the actuator for angle adjustment. Their main function is to change the angle of the rotating frame 7 relative to the fixed frame 6 by extending or retracting. When the hydraulic rods 21 extend or retract, they will drive the rotating frame 7 to rotate around the rotation connection point with the fixed frame 6, thereby realizing the adjustment of the snowplow 8 in the horizontal direction. Since both ends are rotatably connected, this connection method can flexibly transmit power and adapt to the angle changes of the rotating frame 7 during the movement.

[0028] Among them, such as Figures 1-4As shown, a support plate 31 is fixedly connected to the upper end of the adjusting plate 5 on the side away from the hydraulic rod 4. A hydraulic rod 32 is hinged to the lower bottom surface of the support plate 31. The support plate 31 is fixed to the upper end of the adjusting plate 5 on the side away from the hydraulic rod 4, and its function is to provide a mounting fulcrum for the hydraulic rod 32. The other end of the hydraulic rod 32 corresponds to the snowplow 8. One end of the hydraulic rod 32 is hinged to the lower bottom surface of the support plate 31, and the other end corresponds to the snowplow 8. It finely adjusts the angle of the snowplow 8 through its own extension and retraction. When the hydraulic rod 32 extends or retracts, it will exert an upward or downward force on the snowplow 8, causing the snowplow 8 to produce a slight angle change around the connection point with the rotating frame 7, so as to achieve fine adjustment of the angle of the snowplow 8 to better adapt to complex and changing road conditions.

[0029] Among them, such as Figures 1-4 As shown, a connecting seat 41 is fixedly connected to the side of the snowplow 8 near the hydraulic rod 32. A rotating ball 42 is rotatably connected inside the connecting seat 41. The connecting seat 41 provides installation space and a support structure for the rotating ball 42, securely connecting it to the snowplow 8. The outer wall of the rotating ball 42 is fixedly connected to one end of the hydraulic rod 32. The function of the rotating ball 42 is to achieve flexible multi-angle connection between the hydraulic rod 32 and the snowplow 8. It allows the hydraulic rod 32 to smoothly transmit power during extension and retraction, regardless of the direction from which force is applied to the snowplow 8.

[0030] Furthermore, such as Figures 1-4 As shown, multiple sliding rods 51 are slidably connected inside both sides of the snowplow 8. One end of each sliding rod 51 is fixedly connected to an extension plate 52. The multiple sliding rods 51 are slidably connected inside both sides of the snowplow 8, serving to connect the snowplow 8 and the extension plate 52 and guide the movement direction of the extension plate 52. They firmly connect the extension plate 52 to the snowplow 8, allowing the extension plate 52 to extend and retract under the control of the snowplow 8. At the same time, the extension plate 52 bears a certain external force when working, ensuring the stability of the structure. The extension plate 52 is fixed to one end of the multiple sliding rods 51 and connected to the snowplow 8 through the sliding rods 51. The extension plate 52 can increase the effective working width of the snowplow 8. When encountering a wider road surface or an area with a large amount of snow, the extension plate 52 extends to improve snow removal efficiency. When not needed, it can be retracted into the snowplow 8, making it convenient for the equipment to travel or be stored in narrow spaces.

[0031] Furthermore, such as Figures 1-4As shown, a hydraulic telescopic rod 61 is fixedly connected to the side of the snowplow 8 near the extension plate 52. The output end of the hydraulic telescopic rod 61 is fixedly connected to the extension plate 52. The hydraulic telescopic rod 61 is the power component that controls the movement of the extension plate 52. The telescopic action is achieved by the pressure change of the internal hydraulic oil. When it is necessary to increase the snow removal width, the hydraulic telescopic rod 61 extends and pushes the extension plate 52 to move outward. When it is necessary to reduce the snow removal width or when the equipment is in a non-operating state, the hydraulic telescopic rod 61 shortens and drives the extension plate 52 to retract inward.

[0032] Among them, such as Figures 1-4 As shown, multiple lifting rods 71 ​​are hinged to the side of the vehicle body connecting frame 1 away from the angle adjustment structure 2. The main function of the multiple lifting rods 71 ​​is to adjust the overall height of the snowplow 8. The lifting rods 71 ​​can raise or lower the snowplow 8 to adapt to different thicknesses of snow, different heights of road obstacles, and the loading needs of different types of vehicles.

[0033] like Figures 1-4 As shown, the principle of the vehicle snowplow terrain-adaptive suspension device provided in this embodiment is as follows: The lifting rod 71 drives the vehicle body connecting frame 1 to move upward or downward as a whole. Then, the angle of the adjusting plate 5 is adjusted by controlling the extension and retraction of the six hydraulic rods 4. When the adjusting plate 5 rotates, it drives the fixed frame 6 and the support plate 31 to move synchronously. Under the action of multiple hydraulic rods 21, the angle of the rotating frame 7 is adjusted. When the rotating frame 7 rotates, it drives the snowplow 8 to rotate synchronously. The extension and retraction of the hydraulic rod 32 drives the rotating ball 42 to move. The rotating ball 42 drives the connecting seat 41 to move synchronously. The movement of the connecting seat 41 pulls or pushes the upper side of the snowplow 8 to move, changing the upward or downward angle of one side of the snowplow 8. Under the action of the hydraulic telescopic rod 61, it pushes or pulls the extension plate 52 to move. While the extension plate 52 moves, it drives multiple sliding rods 51 to slide inside the snowplow 8, changing the width of the snowplow 8.

[0034] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" as used throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to." "Approximately" means that within an acceptable margin of error, those skilled in the art can solve the technical problem and substantially achieve the technical effect within a certain margin of error.
