Description

Technical Field

[0001] This invention relates to the field of suspension adjustment detection technology, and in particular to an active suspension adjustment detection component and a suspended lawnmower. Background Technology

[0002] Overhead lawnmowers, with their flexible operating characteristics, are widely used in agricultural / pastoral pastures, hilly areas, and public green spaces for harvesting hay and mowing lawns. The rationality of the suspension structure adjustment directly determines the cutting quality and the service life of the equipment. Currently, most existing overhead lawnmowers use manual operation for suspension adjustment, relying on operators to adjust the cutting height, blade gap, and suspension angle based on experience. This lack of manual adjustment based on the actual working environment results in several technical shortcomings.

[0003] Regarding ground height adaptation, the work area often presents uneven terrain and varying slopes. Existing suspended lawnmowers lack an effective real-time ground height detection mechanism, making it impossible to dynamically sense changes in ground undulations. Operators find it difficult to adjust the suspension height accurately in real time, leading to problems such as the cutting disc easily getting stuck in the soil, colliding with ground protrusions, or uneven stubble height and missed cuts. This not only affects the cutting effect but also accelerates the wear and tear on components such as the cutting disc and blade guard, reducing work efficiency.

[0004] Regarding hard object detection and cutting parameter control, the work area often contains hard objects such as rocks and tree stumps. Existing equipment lacks targeted hard object detection components, making it impossible to identify hard objects in a timely manner and automatically adjust the cutting gap and height during the cutting process. When the cutting disc comes into contact with hard objects, blade wear and deformation are likely to occur, which may even lead to damage to the suspension structure and equipment failure. This not only increases maintenance costs but also poses safety hazards. At the same time, areas near hard objects are prone to missed cuts, affecting the integrity of the operation.

[0005] While some existing smart lawnmowers attempt to integrate sensors for height adjustment or obstacle avoidance, they are mostly designed for small, flat areas and are not suitable for the complex operating environment of suspended lawnmowers. Furthermore, they cannot simultaneously achieve ground height detection, hard object recognition, and coordinated active control of cutting gap and height, resulting in poor adaptability and practicality. Therefore, developing an active suspension adjustment and detection component and a suspended lawnmower capable of real-time detection of ground height and hard objects in the cutting path, and automatically adjusting the cutting gap and suspension height to overcome the shortcomings of existing technologies, has become an urgent technical problem to be solved in this field. Summary of the Invention

[0006] The technical problem to be solved by this invention is that the adjustable range of the suspension control mechanism of the current suspended lawnmower is limited, its ability to identify and deal with obstacles is weak, and its versatility is poor.

[0007] The technical solution adopted by the present invention to solve its technical problem is: an active suspension adjustment and detection component, including a top connecting seat and a bottom connecting member for connecting a movable cutting head. The top connecting seat includes an arc-shaped guide rail, an arc-shaped adjustment seat slidably installed inside the arc-shaped guide rail, a main and driven shaft movably assembled inside the arc-shaped adjustment seat, a belt pulley transmission component, a first embedded electric control support rod and a second embedded electric control support rod installed inside the arc-shaped adjustment seat, and a synchronous lifting control cover controlled by the first embedded electric control support rod. The bottom connecting member is connected to the bottom telescopic section of the second embedded electric control support rod through the top connecting member. A self-adjusting detection component is installed on the synchronous lifting control cover and the bottom connecting member.

[0008] An upper control strut is hinged to the side wall of the arc-shaped adjustment seat, and the arc-shaped adjustment seat is controlled to slide and adjust along the arc-shaped guide rail by means of the upper control strut.

[0009] The arc-shaped adjusting seat has a centrally located assembly through hole with openings at the top and bottom. An internal bearing for assembling the driving and driven shafts is installed inside the centrally located assembly through hole.

[0010] The belt drive assembly includes a top driven gear axially mounted on the upper end of the driving and driven shafts and a lateral driven gear that is driven by the top driven gear through a drive belt.

[0011] The arc-shaped adjustment seat has a lower mounting blind hole for installing the first embedded electric control support rod and the second embedded electric control support rod.

[0012] The synchronous lifting control cover includes an inner compression ring fixed to the extended end of the first embedded electric control support rod, an outer protective cover fixed to the periphery of the outer compression ring by an outer bracket, an embedded synchronous guide rail fixed to the inner side of the inner compression ring, and a synchronous control ring slidably installed inside the embedded synchronous guide rail.

[0013] The bottom connector includes a central control ring installed at the extended end of the second embedded electric control strut, a bottom rotating seat inserted inside the central control ring, and a lateral mounting bracket fixed on the outer arc surface of the bottom rotating seat. The bottom rotating seat has a central control through hole at its center position that mates with the main and driven shafts. The main and driven shafts are inserted into the central control through hole from top to bottom and slide together with the bottom rotating seat. The main and driven shafts control the rotation of the bottom rotating seat synchronously by rotating on their own.

[0014] The self-regulating detection component includes an optical sensing probe fixedly mounted on the outer side of the external protective cover and an embedded pressure sensor module mounted on a lateral mounting bracket.

[0015] A suspended lawnmower includes a lawnmower frame and a lawnmower operating cover fixed to the lawnmower frame. At least one active suspension adjustment detection component and a drive motor for synchronously driving the active suspension adjustment detection component are installed on the operating cover. A detachable upper sealing cover is installed on the upper surface of the operating cover.

[0016] The lawnmower's operating cover is fixedly equipped with LED lights for supplemental lighting.

[0017] The beneficial effects of this invention are: (1) By setting up a self-regulating detection component, the present invention can realize real-time detection of ground height undulations and hard objects in the cutting path. Combined with the synergistic effect of the first embedded electric control support rod, the second embedded electric control support rod and the upper control support rod, the cutting gap and cutting height can be automatically and significantly adjusted, solving the problem that existing suspended lawn mowers cannot actively adapt to the working environment. (2) Power is transmitted stably and synchronously through the belt pulley drive assembly. It is also located on the top outside for easy maintenance. In addition, the built-in bearing reduces component wear and extends the service life of the equipment. (3) The synchronous lifting control cover can not only play a protective role during idle time, but also control the cutting radius through independent lifting, while improving the stability of the control; (4) The design of the detachable top-mounted sealed cover and LED light group for supplementary lighting improves the equipment’s maintenance convenience and adaptability to complex environments. The overall structure is reasonably designed and highly versatile. It can be widely used in various types of suspended lawn mowers, effectively improving cutting quality and work efficiency, and reducing maintenance costs and safety hazards. (5) By using the self-regulating detection components installed on the synchronous lifting control cover and bottom connector, the recognition accuracy of the ground and hard objects can be greatly improved by using optical detection + pressure detection. At the same time, the lifting and spacing of the cutting mechanism are automatically controlled, and the self-control capability is also greatly improved. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The diagram illustrates an active suspension adjustment and detection component and a suspended lawnmower. The component includes a lawnmower frame 28, on which a lawnmower operating cover 29 is fixedly mounted. A detachable upper-mounted sealing cover 31 is installed on the upper surface of the operating cover 29 for easy maintenance. An LED light group 32 for supplemental lighting is fixedly mounted on the inner wall of the operating cover 29, providing illumination for the optical sensing probe 26 in low-light conditions to ensure detection accuracy. An active suspension adjustment and detection component and a drive motor 30 for synchronously driving the component are mounted on the operating cover 29. The output of the drive motor 30 is connected to a lateral driven gear 15, providing power for the equipment's operation.

[0028] The active suspension adjustment and detection assembly includes a top connecting seat and a bottom connecting piece for connecting a movable cutting head. The top connecting seat includes an arc-shaped guide rail 1, inside which an arc-shaped adjustment seat 2 is slidably installed. An upper control support rod 10 is hinged to the side wall of the arc-shaped adjustment seat 2. By extending or retracting the upper control support rod 10, the arc-shaped adjustment seat 2 can be controlled to slide along the arc-shaped guide rail 1, thereby adjusting the suspension angle to adapt to different slope working scenarios. The arc-shaped adjustment seat 2 has a central mounting through hole 11 with openings at the top and bottom. An internal bearing 12 is installed inside the central mounting through hole 11. A main and driven shaft 3 is movably mounted inside the internal bearing 12. The internal bearing 12 can reduce the friction force when the main and driven shaft 3 rotates, ensuring smooth rotation.

[0029] The arc-shaped adjusting seat 2 houses a belt pulley transmission assembly 4. The belt pulley transmission assembly 4 includes a top driven gear 13 axially mounted on the upper end of the main and driven shafts 3, and a lateral driven gear 15 that is driven by the top driven gear 13 via a transmission belt 14. The lateral driven gear 15 is connected to the output end of the drive motor 30. After the drive motor 30 starts, it drives the lateral driven gear 15 to rotate, which in turn drives the top driven gear 13 and the main and driven shafts 3 to rotate synchronously via the transmission belt 14. The arc-shaped adjusting seat 2 has a lower mounting blind hole 16 inside. A first embedded electric control support rod 5 and a second embedded electric control support rod 6 are installed inside the lower mounting blind hole 16. The lower mounting blind hole 16 serves to fix and limit the two electric control support rods, preventing displacement during operation.

[0030] The extended end of the first embedded electric control support rod 5 is fixed with a synchronous lifting control cover 7. The synchronous lifting control cover 7 includes an inner compression ring 17, an outer bracket 18, an outer protective cover 19, an embedded synchronous guide rail 20, and a synchronous control ring 21. The inner compression ring 17 is fixed to the extended end of the first embedded electric control support rod 5. One end of the outer bracket 18 is connected to the inner compression ring 17, and the other end is connected to the outer protective cover 19, fixing the outer protective cover 19 to the periphery of the inner compression ring 17 for protection. The embedded synchronous guide rail 20 is fixed inside the inner compression ring 17, and the synchronous control ring 21 is slidably installed inside the embedded synchronous guide rail 20 to ensure that the synchronous lifting control cover 7 rises and falls smoothly.

[0031] The bottom telescopic section of the second embedded electric control support rod 6 is connected to the bottom connector via the top connector 8. The bottom connector includes a central control ring 22, a bottom rotating seat 23, and a lateral mounting bracket 24. The central control ring 22 is installed at the extended end of the second embedded electric control support rod 6. The bottom rotating seat 23 is inserted into the central control ring 22. A central control through hole 25 is provided at the center of the bottom rotating seat 23. The main and driven shafts 3 are inserted into the central control through hole 25 from top to bottom, and slide up and down with the bottom rotating seat 23. At the same time, when the main and driven shafts 3 rotate, they can drive the bottom rotating seat 23 to rotate synchronously, thereby driving the cutting head to rotate to complete the cutting operation. The lateral mounting bracket 24 is fixed on the outer arc surface of the bottom rotating seat 23 and is used to install the embedded pressure sensor module 27.

[0032] The synchronous lifting control cover 7 and the bottom connector are equipped with a self-regulating detection component 9. The self-regulating detection component 9 includes an optical sensor probe 26 and an embedded pressure sensor module 27. The optical sensor probe 26 is fixedly installed on the outer side of the outer protective cover 19 and is used to detect the ground height undulation and hard objects in the cutting path in real time. The embedded pressure sensor module 27 is installed on the lateral mounting bracket 24 and is used to detect the pressure change of the cutting head in real time. The data collected by both are transmitted to the equipment control system to provide data support for active control.

[0033] In this embodiment, the optical sensing probe 26 adopts a laser rangefinder sensor, which has high detection accuracy and fast response speed; the embedded pressure sensor module 27 adopts a piezoelectric pressure sensor, which can accurately detect minute pressure changes; the first embedded electric control support rod 5, the second embedded electric control support rod 6 and the upper control support rod 10 all adopt electric telescopic rods, which have high control accuracy and rapid response.

[0034] The working principle and process of this invention are as follows: The control system (not labeled) on the device serves as the core control unit, and is electrically connected to the self-regulating detection component 9, the first embedded electric control support rod 5, the second embedded electric control support rod 6, the upper-mounted regulating support rod 10, and the drive motor 30 to form a closed-loop control system. Specifically, the optical sensing probe 26 in the self-regulating detection component 9 uses the laser ranging principle to emit laser signals to the working ground and the cutting path in real time. By receiving the reflected signals, it calculates the ground height undulation data, the vertical distance between the ground and the cutting head, and the size and position information of hard objects in the cutting path. The embedded pressure sensor module 27 is fitted to the lateral mounting bracket 24 and can collect data such as cutting resistance and contact pressure experienced by the cutting head during operation in real time. When the cutting head contacts a hard object or encounters abnormal resistance, the pressure data will instantly exceed a preset threshold. The optical sensor probe 26 and the embedded pressure sensor module 27 transmit all the collected data to the control system in real time. The control system has preset ground height adaptation threshold, hard object recognition threshold and pressure safety threshold. By analyzing and comparing the received data, it automatically generates control commands and synchronously controls the extension and retraction of the first embedded electric control support rod 5, the second embedded electric control support rod 6 and the upper control support rod 10 to achieve active adaptive control of cutting gap, cutting height and suspension angle. At the same time, the drive motor 30 transmits power to the main and driven shafts 3 through the belt pulley transmission assembly 4. The main and driven shafts 3 drive the bottom rotating seat 23 and the cutting head connected to it to rotate at high speed to complete the cutting of lawn and pasture. The whole process does not require manual intervention and realizes fully automated adaptation operation.

[0035] The specific working process is as follows: Before starting the equipment, the operator needs to check the assembly status of each component to ensure that the arc-shaped guide rail 1 and the arc-shaped adjustment seat 2 slide smoothly, the main and driven shafts 3 and the built-in bearings 12 fit tightly, and the transmission belt 14 has appropriate tension. Then, the equipment power is turned on, and the control system, drive motor 30, self-regulating detection component 9 and supplementary LED light group 32 are synchronously powered on and initialized. After initialization, the equipment enters the standby state. At this time, the first embedded electric control support rod 5, the second embedded electric control support rod 6 and the upper adjustment support rod 10 are all in the initial retracted state, the synchronous lifting and lowering control cover 7 is in the high position, and the cutting head is in the vertical state. After the equipment is started, the drive motor 30 begins to run. The output of the drive motor 30 drives the lateral driven gear 15 to rotate at a constant speed. The lateral driven gear 15 drives the top driven gear 13 to rotate synchronously through the transmission belt 14. The top driven gear 15 is axially fixed to the main and driven shafts 3, thereby driving the main and driven shafts 3 to rotate at high speed around the built-in bearing 12. The main and driven shafts 3 pass through the central control through hole 25 and slide with the bottom rotating seat 23. Its rotational power is transmitted to the bottom rotating seat 23 through the limiting structure on the inner wall of the central control through hole 25, causing the bottom rotating seat 23 to rotate synchronously. The bottom rotating seat 23 drives the cutting head to rotate at high speed through the lateral mounting bracket 24. The centrifugal force causes the cutting head to flip outward. The cutting angle is adjusted and controlled according to the rotation speed to enter the normal cutting operation state. At the same time, the self-regulating detection component 9 starts synchronously. The optical sensor probe 26 is fixed on the outer side of the outer protective cover 19 and always faces the ground and the cutting path in front to scan and detect. The embedded pressure sensor module 27 collects the pressure data of the cutting head in real time. The data from both are transmitted synchronously to the control system. When the optical sensor 26 detects a protrusion on the ground, it immediately transmits the height and position data of the protrusion to the control system. After comparing the data with a preset height threshold, the control system quickly sends a retraction command to the second embedded electric control support rod 6. The telescopic section of the second embedded electric control support rod 6 retracts upward, driving the bottom connector to rise as a whole through the top connector 8. The bottom connector drives the cutting head to rise synchronously, matching the height of the ground protrusion until the cutting head maintains a safe distance from the protruding surface, preventing the cutting head from colliding with the ground protrusion and causing blade wear or deformation. When the optical sensor 26 detects a depression on the ground, the control system receives the depression depth data and controls the second embedded electric control support rod 6 to extend, driving the bottom connector and the cutting head to descend synchronously, ensuring that the cutting head always maintains a preset cutting height with the ground, avoiding problems such as uneven stubble height and missed cuts.When the optical sensor probe 26 detects hard objects such as stones or tree stumps in the cutting path, it immediately sends the position and size signal of the hard object to the control system. The control system immediately activates the emergency control mode. On one hand, it controls the first embedded electronic support rod 5 to extend downward, driving the synchronous lifting control cover 7 to descend as a whole. The synchronous control ring 21 slides along the embedded synchronous guide rail 20 to ensure the smooth descent of the synchronous lifting control cover 7. As the synchronous lifting control cover 7 descends, it presses down on the bottom rotating seat 23 during the descent, generating initial acceleration through the bottom rotating seat 23. Finally, it continues to descend, completing synchronous acceleration before touching the cutting head, maintaining synchronous rotation speed with the cutting head. This allows the angle of the cutting head to be pressed downward, making the cutting blade... The cutting diameter of the head decreases to avoid hard objects on the ground, and the cutting gap is adjusted to reduce the cutting range. On the other hand, the second embedded electric control support rod 6 is controlled to extend quickly, driving the cutting head to rise and quickly avoid hard objects. At the same time, the control system appropriately reduces the speed of the drive motor 30 to reduce the inertial impact force of the cutting head. If the hard object is too large, the upper control support rod 10 can be used to control the sliding adjustment of the arc-shaped adjustment seat 2 to further expand the cutting gap. After the equipment has completely passed the hard object, the control system controls the first embedded electric control support rod 5 and the second embedded electric control support rod 6 to reset, and the synchronous lifting control cover 7 rises. The cutting head returns to the normal cutting height and cutting gap, and the drive motor 30 returns to the normal speed to continue the cutting operation. When the embedded pressure sensor module 27 detects that the pressure on the cutting head exceeds the preset safety threshold (such as when the cutting head accidentally touches a hard object and is not recognized in time by the optical sensor probe 26), it will immediately send an abnormal pressure signal to the control system. The control system will respond quickly within 0.5 seconds. On the one hand, it will control the drive motor 30 to stop running, driving the main and driven shafts 3, the bottom rotating seat 23 and the cutting head to stop rotating. On the other hand, it will control the second embedded electric control support rod 6 to extend quickly, driving the cutting head to rise, so as to avoid further damage to the cutting head, the bottom rotating seat 23 and the main and driven shafts 3 caused by the hard object. At the same time, the control system will issue an alarm signal to remind the operator to check the work area. The equipment can only be restarted to continue operation after the hard object obstacle is removed. When the ambient light is dim (such as on a cloudy day or at dusk), the detection accuracy of the optical sensor probe 26 will be affected. At this time, the control system automatically starts the supplementary LED light group 32. The supplementary LED light group 32 is fixed to the inner wall of the lawnmower operating cover 29 and emits uniform light towards the cutting area to provide sufficient supplementary light for the optical sensor probe 26, ensuring the detection accuracy of the optical sensor probe 26 and avoiding detection errors due to insufficient light. In order to prevent the LED light group 32 from being blocked by the cutting grass, a high-pressure jet nozzle can also be set on one side of the LED light group 32, and the high-pressure jet nozzle can be used to remove debris by connecting an external air pump.The first embedded electric control support rod 5 and the second embedded electric control support rod 6 retract upwards, retracting the bottom connecting piece into the synchronous lifting control cover 7, improving protection and safety. After the operation is completed, the operator turns off the power to the equipment, the drive motor 30 stops running, the cutting head stops rotating, and the control system controls the first embedded electric control support rod 5, the second embedded electric control support rod 6, and the upper control support rod 10 to return to their initial state. The bottom connecting piece and the synchronous lifting control cover 7 rise to the high position, the cutting head returns to its initial height, and the supplementary lighting LED light group 32 and the self-regulating detection component 9 are simultaneously de-energized. During later maintenance, the operator can disassemble the detachable upper sealing cover 31 to clean, inspect, and replace components such as the drive motor 30, the belt pulley transmission component 4, and the main and driven shafts 3 inside the lawnmower operating cover 29. At the same time, check whether the detection surface of the optical sensor probe 26 is obstructed by dust or weeds, and clean the debris on the surface of the embedded pressure sensor module 27 to ensure that all components operate normally and extend the service life of the equipment.
