Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, and in particular to a lawnmower. Background Technology

[0002] Lawn mowers (robotic lawnmowers) have a cutting mechanism at their bottom. The cutting edge of the blade is relatively close to the outer contour of the mower's casing. Therefore, existing blades are usually fitted with protective covers on both sides to increase the width of the mower's profile, reducing the probability of the user touching the blades and meeting safety regulations. However, directly adding protective covers to existing lawnmowers not only increases their transport size but also increases the risk of breakage due to bumps during transport. Therefore, protective covers are often installed on the mower before use, solving the problems of increased size and breakage risk during transport. However, in current technology, users often forget to install the protective covers before use, which can easily lead to safety issues. Summary of the Invention

[0003] This utility model provides a lawnmower to solve the problem that in the current technology, users often forget to install protective parts before use, which can easily lead to safety problems.

[0004] A lawnmower includes a body, a first protective component, and an in-situ detection mechanism; The first protective component is detachably installed on the side of the machine body for the purpose of protecting the machine body; The in-situ detection mechanism includes a trigger module and a sensing module; the sensing module is disposed on the body, and the trigger module is disposed on the first protective component. The sensing module and the trigger module cooperate to detect whether the first protective component is installed in place.

[0005] Preferably, the side of the machine body is provided with a mounting part arranged along the front-rear direction of the lawn mower and an overlapping part located on the front and / or rear side of the mounting part; The first protective component includes a fixing part and an extension part disposed on the fixing part. The fixing part is detachably installed on the mounting part, and the extension part is adapted to connect with the overlapping part.

[0006] Preferably, the mounting portion is provided with an adaptation notch and a mounting protrusion disposed within the adaptation notch; The fixing part abuts against the adaptation notch and is fixed to the mounting part by fasteners; The fixing part is provided with a groove, and the mounting protrusion is embedded in the groove.

[0008] Preferably, the fixing part is provided with a plurality of first reinforcing ribs; the fixing part and the extension part are provided with a plurality of second reinforcing ribs at the parts away from the mounting part, and a hollow part for installing the anti-detachment component is formed between two adjacent second reinforcing ribs.

[0009] Preferably, the in-situ detection mechanism further includes a controller, which is connected to the sensing module and the cutting mechanism of the lawnmower, and controls the working state of the cutting mechanism according to the signal from the sensing module.

[0010] Preferably, the number of the first protective components is N, where N is greater than or equal to 1, and each first protective component corresponds to one of the triggering modules and one of the sensing modules; The controller is connected to N sensing modules and controls the working state of the cutting mechanism based on the signals from the N sensing modules.

[0011] Preferably, the lawnmower further includes a cutting mechanism and a second protective component; The cutting mechanism is mounted on the machine body; The second protective component is installed on the cutting mechanism, located between the first protective component and the cutting mechanism.

[0012] Preferably, the bottom of the second protective member is located below the location of the cutting disc of the cutting mechanism.

[0013] Preferably, the lawnmower further includes a lifting mechanism, which is located inside the machine body and connected to the cutting mechanism, for adjusting the position of the cutting mechanism and the second protective component.

[0014] The lawnmower provided in this embodiment features a first protective component that is detachably installed on the side of the machine body during installation. This provides a reliable protective barrier for the machine, effectively preventing damage from collisions and scratches during operation. This reduces the risk of damage due to accidental impacts, extends the lifespan of the lawnmower, reduces maintenance costs and the frequency of component replacement, and lowers the probability of users touching the blade disc, thus meeting safety regulations. The detachable installation method makes maintenance and replacement of the first protective component more convenient. When the first protective component is damaged or needs cleaning, the user can easily remove it for repair or cleaning and then reinstall it without complicated operations or professional skills, improving user convenience and autonomy.

[0015] The in-situ detection mechanism includes a trigger module and a sensing module. During installation, the sensing module is mounted on the machine body, and the trigger module is mounted on the first protective component. The sensing and trigger modules work together to detect whether the first protective component is properly installed. This setup allows for timely and accurate detection of the first protective component's installation status, which is crucial for the safe use of the lawnmower. If the first protective component is not properly installed, the lawnmower may expose dangerous parts during operation, increasing the risk of injury to the operator or those nearby. With the in-situ detection mechanism, once the first protective component is detected as not being installed correctly, the lawnmower can take appropriate safety measures, such as stopping operation or issuing an alarm, reminding the user to address the issue promptly. This effectively avoids safety accidents caused by the missing protective component and protects the user's personal safety. The in-situ detection mechanism adds an intelligent element to the lawnmower. Users no longer need to manually check whether the first protective component is installed correctly; the lawnmower can automatically complete the detection and provide feedback, making operation simpler and more efficient. At the same time, it lays the foundation for potentially more advanced intelligent control functions in the future, enhancing the overall technological content and user experience of the lawnmower. By setting up an in-place inspection mechanism, not only are the risks of increased size and breakage during transportation resolved, but the first protective component is also ensured to be installed by the user before use, thereby improving product safety and transportation reliability.

[0016] The trigger module and the sensing module can detect the presence of the device through electrical contacts. When the device makes contact, the sensing circuit is activated, which generates an electrical signal to determine that the first protective component is installed in place. Otherwise, it is not installed in place.

[0017] The trigger module and the sensing module can perform in-situ detection by detecting magnetic flux. The sensing module is a sensor (such as a Hall effect sensor), and the trigger module is a permanent magnet. Specifically, the permanent magnet is installed on the first protective component, and the sensor is installed on a mounting plate inside the body cavity, with the magnetic poles of the permanent magnet facing the sensor. With this setup, the sensor can sense the magnetic flux of the permanent magnet, accurately detecting whether the first protective component is installed correctly. For example, only when the first protective component is correctly installed, and the relative position and distance between the permanent magnet and the sensor meet the set standard, can the sensor sense the appropriate magnetic flux and send a corresponding signal, thereby ensuring the accuracy and reliability of the installation of the first protective component.

[0024] This utility model provides a lawnmower, as shown in the following embodiment. Figure 1 , Figure 2 , Figure 3 and Figure 4 The lawnmower includes a body 1, a first protective component 2, and an in-place detection mechanism 3. The first protective component 2 is detachably installed on the side of the body 1 to protect the body 1. The in-place detection mechanism 3 includes a trigger module 31 and a sensing module 32. The sensing module 32 is located on the body 1, and the trigger module 31 is located on the first protective component 2. The sensing module 32 and the trigger module 31 cooperate to detect whether the first protective component 2 is installed in place.

[0025] As an example, the lawnmower includes a body 1, a first protective component 2, and an in-situ detection mechanism 3. During installation, the first protective component 2 is detachably mounted to the side of the body 1, providing a reliable protective barrier. During operation, it effectively prevents damage to the body 1 from collisions and scratches, reducing the risk of damage due to accidental impacts, extending the lawnmower's lifespan, reducing maintenance costs and the frequency of component replacements, and decreasing the probability of users touching the blades, thus meeting safety regulations. The detachable installation method makes maintenance and replacement of the first protective component 2 more convenient. When the first protective component 2 is damaged or requires cleaning, the user can easily remove it for repair or cleaning and then reinstall it, without requiring complex operations or professional skills, improving user convenience and autonomy.

[0026] The in-situ detection mechanism 3 includes a trigger module 31 and a sensing module 32. During installation, the sensing module 32 is mounted on the machine body 1, and the trigger module 31 is mounted on the first protective component 2. The sensing module 32 and the trigger module 31 work together to detect whether the first protective component 2 is installed correctly. This setup allows for timely and accurate detection of the installation status of the first protective component 2, which is crucial for the safe use of the lawnmower. If the first protective component 2 is not installed correctly, some dangerous parts may be exposed during operation, increasing the risk of injury to the operator or surrounding personnel. With the in-situ detection mechanism 3, once the first protective component 2 is detected as not being installed correctly, the lawnmower can take corresponding safety measures, such as stopping operation or issuing an alarm, reminding the user to handle the situation promptly. This effectively avoids safety accidents caused by the missing protective component and protects the user's personal safety. The in-situ detection mechanism 3 adds an intelligent element to the lawnmower. Users no longer need to manually check whether the first protective component 2 is installed correctly; the lawnmower can automatically complete the detection and provide feedback, making operation simpler and more efficient. At the same time, it lays the foundation for potentially more advanced intelligent control functions in the future, improving the overall technological content and user experience of the lawnmower. By setting up the in-place detection mechanism 3, not only are the problems of increased size and breakage risk during transportation solved, but the first protective component 2 is also ensured to be installed by the user before use, thereby improving product safety and transportation reliability.

[0027] The trigger module 31 and the sensing module 32 can be in-place detection via electrical contacts. When there is an electric contact, the sensing circuit is activated, thereby generating an electrical signal to determine that the first protective component 2 is installed in place; otherwise, it is not installed in place.

[0028] The trigger module 31 and the sensing module 32 can perform in-situ detection by detecting magnetic flux. The sensing module 32 is a sensor (such as a Hall effect sensor), and the trigger module 31 is a permanent magnet. Specifically, the permanent magnet is installed on the first protective component 2, and the sensor is installed on the mounting plate inside the cavity of the body 1, with the magnetic poles of the permanent magnet facing the sensor. With this configuration, the sensor can sense the magnetic flux of the permanent magnet, and accurately detect whether the first protective component 2 is installed correctly. For example, only when the first protective component 2 is correctly installed, and the relative position and distance between the permanent magnet and the sensor reach the set standard, can the sensor sense the appropriate magnetic flux and send a corresponding signal, thereby ensuring the accuracy and reliability of the installation of the first protective component 2.

[0029] In one embodiment, reference is made to Figure 1 , Figure 4 , Figure 5 and Figure 6The machine body 1 has a mounting part 11 arranged along the front and rear direction of the lawn mower on its side and an overlapping part 12 located on the front and / or rear side of the mounting part 11; the first protective member 2 includes a fixing part 21 and an extension part 22 provided on the fixing part 21. The fixing part 21 is detachably installed on the mounting part 11, and the extension part 22 is adapted to connect with the overlapping part 12.

[0030] As an example, the mounting portion 11, arranged along the front-rear direction on the side of the machine body 1, provides a clear and regular installation position for the fixing portion 21 of the first protective component 2. The fixing portion 21 is detachably installed on the mounting portion 11. This corresponding design allows the first protective component 2 to quickly and accurately find its installation position during installation, reducing deviations and errors and ensuring installation accuracy. The cooperation between the mounting portion 11 and the fixing portion 21, through specific connection methods (such as bolt connection, snap-fit ​​connection, etc.), forms a relatively stable connection structure. This stable connection can effectively withstand various external forces generated by the lawnmower during operation, such as vibration and collision, preventing the first protective component 2 from loosening or falling off during use, ensuring that the first protective component 2 is always firmly installed on the machine body 1, providing continuous and reliable protection for the machine body 1. The overlapping portion 12 located on the front and / or rear side of the mounting portion 11, which adapts to the extension portion 22 of the first protective component 2, further enhances the connection stability between the first protective component 2 and the machine body 1. The extension 22 and the overlapping part 12 cooperate to form an additional fixing and supporting structure, which can distribute and bear some of the external force, making the entire installation structure more robust and reliable, and effectively avoiding the loosening problems that may occur due to a single connection method. The first protective member 2 is installed on the mounting part 11 on the side of the body 1 through the fixing part 21, while the extension 22 connects with the overlapping part 12, so that the first protective member 2 can more comprehensively cover the side area of ​​the body 1. This comprehensive coverage can effectively block the direct impact and scratch of external objects (such as stones, branches, etc.) on the side of the body 1, providing more complete protection for the body 1 and reducing the possibility of damage to the body 1 due to external impact. The mounting part 11 is arranged along the front and rear direction of the lawnmower, and the overlapping part 12 is located on the front and / or rear side of the mounting part 11, cooperating with the fixing part 21 and the extension 22 of the first protective member 2, making the overall appearance structure of the lawnmower more coordinated and aesthetically pleasing. The reasonable arrangement of the mounting part 11 and the overlapping part 12 can give full play to the structural performance of the body 1 and the first protective part 2, making the structure of the entire lawnmower more reasonable and compact, and improving the overall stability and reliability of the lawnmower.

[0031] In one embodiment, reference is made to Figure 4 and Figure 5 The mounting part 11 is provided with an adaptation notch and a mounting protrusion 4 provided in the adaptation notch; the fixing part 21 abuts against the adaptation notch and is fixed to the mounting part 11 by fasteners 5; the fixing part 21 is provided with a groove, and the mounting protrusion 4 is embedded in the groove.

[0032] As an example, the fitting notch provides precise spatial positioning for the installation of the fixing part 21. The fixing part 21 abuts against the fitting notch, allowing it to quickly and accurately find the correct position during installation, avoiding offset and misalignment, and greatly improving installation accuracy. This is crucial for ensuring the first protective component 2 can function correctly, as only with accurate installation can the protective component effectively block external objects from harming the machine body 1. The mounting protrusion 4 is embedded in the groove of the fixing part 21; this nested connection structure increases the contact area and friction between the fixing part 21 and the mounting part 11. Simultaneously, the fastener 5 further secures the fixing part 21 to the mounting part 11, forming a double-fixed guarantee. The cooperation between the mounting protrusion 4 and the groove prevents the fixing part 21 from sliding horizontally, while the fastener 5 secures the fixing part 21 vertically, making the entire connection structure more stable and reliable, effectively reducing the possibility of the first protective component 2 loosening due to vibration, collision, etc., during use. When the lawnmower is working, the first protective component 2 is subjected to various external forces. The connection structure, consisting of the fitting notch, mounting protrusion 4, and fastener 5, evenly distributes external forces to the mounting part 11 and the fixing part 21, avoiding localized stress concentration. This prevents damage to the connection points due to excessive localized stress, improving the durability and reliability of the entire mounting structure. The fastener 5 is fixed to the mounting part 11 from the bottom of the fixing part 21, facilitating later installation or maintenance by the user. A receiving cavity is provided within the mounting protrusion 4, and a mounting plate is installed within this cavity, on which the sensing module 32 is mounted. The trigger module 31 is positioned within the location range of the fastener 5, protecting it from easy drop.

[0033] In one embodiment, reference is made to Figure 4 and Figure 5 The fixing part 21 includes a main board 211, an inner sidewall 212 and an outer sidewall 213 extending from opposite sides of the main board 211 in the same direction; the main board 211 is fixed to the mounting part 11 by fasteners 5, and the outer sidewall 213 is higher than the inner sidewall 212; the main board 211, the inner sidewall 212 and the outer sidewall 213 cooperate to form a groove.

[0034] As an example, the main board 211 is fixed to the mounting part 11 by fasteners 5, providing a solid foundation for the entire mounting part 21. Meanwhile, the inner sidewalls 212 and outer sidewalls 213 extend from both sides of the main board 211, increasing the contact area between the mounting part 21 and the mounting part 11. A larger contact area means better stress distribution under load, reducing localized stress concentration, thereby strengthening the connection between the mounting part 21 and the mounting part 11, making the first protective component 2 less prone to loosening or falling off during lawnmower operation. The groove structure formed by the main board 211, inner sidewalls 212, and outer sidewalls 213 provides precise positioning during installation. The mounting protrusion 4 is embedded in the groove, and the shape and size of the groove are adapted to the mounting protrusion 4, guiding the mounting part 21 to be accurately installed in the designated position on the mounting part 11. This precise positioning ensures that the first protective component 2 is always in the correct position, improving installation consistency and accuracy. The design of the outer side wall 213 being higher than the inner side wall 212 creates an effective blocking structure in the horizontal direction. When the lawnmower is subjected to lateral forces, the outer side wall 213 can prevent excessive horizontal movement of the fixing part 21, further enhancing the stability of the installation. Compared with relying solely on fasteners 5 for fixation, this structure can better withstand external impacts under complex working conditions, ensuring that stress is not concentrated at the fixing fastener 5 when the first protective part 2 is under force, thus improving the service life of the first protective part 2.

[0035] In one embodiment, reference is made to Figure 4 , Figure 5 and Figure 6 The fixing part 21 is provided with a plurality of first reinforcing ribs 23; the fixing part 21 and the extension part 22 are provided with a plurality of second reinforcing ribs 24 at the part away from the mounting part 11, and a hollow part for installing the anti-detachment component is formed between two adjacent second reinforcing ribs 24.

[0036] As an example, the multiple first reinforcing ribs 23 provided within the fixing part 21 act like a robust skeleton within it. These ribs effectively disperse various stresses experienced by the fixing part 21 during operation, including stresses caused by lawnmower vibration, collisions, and external impacts. For instance, when the lawnmower operates on complex terrain, the fixing part 21 may be subjected to forces from different directions. The first reinforcing ribs 23 can evenly distribute these forces across the entire structure of the fixing part 21, preventing localized stress concentration that could lead to deformation or damage, thus significantly improving the structural strength and resistance to damage of the fixing part 21. Multiple second reinforcing ribs 24 are provided in the fixing part 21 and the extension part 22, away from the mounting part 11, further enhancing the strength of this part of the structure. As an important component of the first protective member 2, the extension part 22 needs to withstand certain external forces to protect the machine body 1. The presence of the second reinforcing ribs 24 allows the extension part 22 to better maintain its shape and structural integrity when subjected to impacts, scratches, or other external forces. Meanwhile, the first reinforcing rib 23 and the second reinforcing rib 24 work together to form an organic, integrated reinforcement system, enhancing the structural strength of the entire first protective component 2 from different parts and angles, enabling it to more reliably fulfill its protective function. The hollow portion formed between two adjacent second reinforcing ribs 24 provides a precise and suitable position for the installation of the anti-detachment component. This design allows the anti-detachment component to be securely installed within the hollow portion, preventing it from shifting or loosening during installation. For example, when installing some snap-on anti-detachment components that require precise fixing, the size and shape of the hollow portion can be designed according to the requirements of the anti-detachment component, ensuring that the anti-detachment component can be accurately embedded and tightly fitted, thereby effectively preventing the first protective component 2 from falling off due to vibration or other reasons during use. The second reinforcing ribs 24 are arranged around the hollow portion, providing additional support and fixation for the anti-detachment component installed therein. When the first protective component 2 is subjected to external force, the second reinforcing ribs 24 can limit the range of movement of the anti-detachment component, preventing it from falling out of its installation position due to force. This stable anti-detachment structure ensures that the first protective component 2 is always firmly connected to the body 1, maintaining a good connection even in harsh working environments, thus improving the safety and reliability of the lawnmower. By incorporating reinforcing ribs and a hollow section, the weight of the fixed part 21 and the extension part 22 is rationally controlled while ensuring structural strength. The reinforcing ribs, with their reasonable layout and size design, significantly improve structural strength without adding excessive material, while the hollow section reduces unnecessary material usage. This weight-reducing design helps lower the overall weight of the lawnmower, improving its maneuverability and operational flexibility, while also reducing material costs. The reinforcing ribs can be designed as wedge-shaped structures.

[0037] In one embodiment, the in-situ detection mechanism 3 further includes a controller connected to the sensing module 32 and the cutting mechanism 6 of the lawnmower, and controls the working state of the cutting mechanism 6 according to the signal from the sensing module 32.

[0038] As an example, the sensing module 32 can detect in real time whether specific conditions or objects are in the correct position, such as whether the first protective component 2 is installed in place, whether there are obstacles or people approaching the cutting area, etc. When the sensing module 32 detects an abnormality, such as the first protective component 2 being missing or personnel entering the danger zone, the controller will quickly receive the signal and immediately control the cutting mechanism 6 to stop working. This can effectively avoid accidental injury to personnel or equipment caused by the cutting mechanism 6 operating in a dangerous state, greatly improving the safety of lawnmower use. The controller precisely controls the working status of the cutting mechanism 6 based on the signal from the sensing module 32. The sensing module 32 can monitor in real time whether the first protective component 2 is installed in place. Once an abnormality is detected, the controller will react immediately and automatically stop the cutting mechanism 6. This rapid response mechanism can reduce downtime caused by malfunctions or dangerous situations, allowing the lawnmower to resume normal operation more quickly and improving overall work efficiency. The combination of the in-situ detection mechanism 3 and the controller is an important step in the development of lawnmowers towards automation. Through the real-time perception of the working status by the sensing module 32 and the automatic control of the cutting mechanism 6 by the controller, the lawnmower can achieve a certain degree of autonomous operation.

[0039] In one embodiment, the number of first protective components 2 is N, where N is greater than or equal to 1. Each first protective component 2 corresponds to a trigger module 31 and a sensing module 32. The controller is connected to the N sensing modules 32 and controls the working state of the cutting mechanism 6 according to the signals from the N sensing modules 32.

[0040] As an example, multiple first protective components 2 are distributed at different key locations on the lawnmower, enabling them to detect potential hazards from multiple angles and areas. For instance, first protective components 2 can be installed in front of or on both sides of the lawnmower to detect obstacles (such as stones or branches) or people approaching the cutting area from all directions. The sensing module 32 corresponding to each first protective component 2 can promptly capture local hazard signals, greatly expanding the hazard detection range compared to a single protective component and improving the lawnmower's safety in complex environments. Since each first protective component 2 has an independent sensing module 32, when a sensing module 32 emits an abnormal signal, the controller can accurately determine the specific location of the hazard. For example, if the sensing module 32 corresponding to the first protective component 2 on the right side of the lawnmower detects an abnormality, the controller can know that there is a hazard on the right side and thus control the cutting mechanism 6 to react accordingly, such as stopping the right-side cutting blades to prevent the hazard from escalating further. This also reduces the risk of a complete shutdown due to misjudgment, improving work efficiency. N first protective components 2 form a multi-level safety protection system. Even if one of the first protective components 2 fails to detect danger in time due to malfunction or special circumstances, other first protective components 2 may still function, providing additional safety. This redundant design enhances the lawnmower's ability to respond to sudden dangers and reduces the risk of accidents. Through the coordinated work of multiple first protective components 2 and the sensing module 32, the controller can quickly and accurately determine the working status and adjust the cutting mechanism 6 in a timely manner, reducing downtime caused by waiting for manual intervention or misjudgment.

[0041] In one embodiment, reference is made to Figure 3 The lawnmower also includes a cutting mechanism 6 and a second protective component 7; the cutting mechanism 6 is mounted on the body 1; the second protective component 7 is mounted on the cutting mechanism 6 and is located between the first protective component 2 and the cutting mechanism 6.

[0042] As an example, the first protective component 2 and the second protective component 7 form a dual safety protection system. The first protective component 2, acting as the first line of defense, can initially detect larger obstacles or hazards, such as large rocks or trees. When an anomaly is detected, it can promptly report information to the controller, allowing the cutting mechanism 6 to make corresponding adjustments. The second protective component 7, installed on the cutting mechanism 6 and closer to the cutting area, provides secondary protection against small foreign objects or closer hazards that the first protective component 2 may not completely block. For example, small twigs or debris may be outside the detection range of the first protective component 2, but the second protective component 7 can prevent them from entering the cutting area, avoiding damage to the cutting blades or causing danger, greatly improving the safety of the lawnmower. The second protective component 7, located between the first protective component 2 and the cutting mechanism 6, effectively prevents personnel or objects from accidentally coming into contact with the high-speed rotating cutting blades. During lawnmower operation, even if the first protective component 2 malfunctions for some reason or fails to completely block approaching objects, the second protective component 7 can still provide final protection, reducing the risk of personnel being cut by the cutting blades or objects being caught in the cutting mechanism 6 and causing damage, thus ensuring the safety of the operator and the surrounding environment. The second protective component 7 works in conjunction with the first protective component 2, enabling the lawnmower to better adapt to complex working environments. For example, in areas with dense weeds and many obstacles, the first protective component 2 can initially clear and detect larger obstacles, while the second protective component 7 further filters and blocks smaller debris, ensuring that the cutting mechanism 6 can work normally in various complex environments, improving the lawnmower's adaptability and operational reliability. The second protective component 7 is installed on the cutting mechanism 6 and located between the first protective component 2 and the cutting mechanism 6. This structural design makes reasonable use of space, neither affecting the normal operation of the cutting mechanism 6 nor hindering its protective function. At the same time, this layout makes the overall structure of the lawnmower more compact, reducing the size and weight of the equipment, and improving its portability and operability.

[0043] In one embodiment, reference is made to Figure 3 The bottom of the second protective component 7 is located lower than the cutter head of the cutting mechanism 6.

[0044] As an example, the bottom of the second protective element 7 is lower than the blade head, forming a more comprehensive protective barrier. During mowing, various debris on the ground, such as small stones, twigs, and metal objects, are blocked by the second protective element 7 before being sucked into the cutting area by the blade head. Because the protective element is positioned lower, it can intercept foreign objects that are closer to the ground and might otherwise bypass the higher protective element to enter the blade head, greatly reducing the risk of foreign objects colliding with the blades in the cutting area. This avoids dangerous situations such as blade damage or injury caused by flying debris. For operators and those nearby, the lower bottom of the second protective element 7 increases the safety distance. Even if someone accidentally approaches the lawnmower, the lower position of the second protective element 7 can prevent body parts (such as feet and legs) from contacting the high-speed rotating blade head earlier, effectively reducing the probability of cuts, abrasions, and other injuries caused by accidental contact, and improving safety during operation and use.

[0045] In one embodiment, reference is made to Figure 3 The lawnmower also includes a lifting mechanism 8, which is located inside the body 1 and connected to the cutting mechanism 6. The lifting mechanism 8 is used to adjust the position of the cutting mechanism 6 and the second protective component 7.

[0046] As an example, different scenarios have diverse requirements for lawn height. In a home garden, the homeowner may prefer a low and neat lawn to create a refined and beautiful landscape; while in professional venues such as parks and golf courses, different areas may require lawns of varying heights based on functional and aesthetic needs. The lifting mechanism 8 can precisely adjust the height of the cutting mechanism 6, thereby controlling the remaining grass height, allowing the lawnmower to easily handle various grass height requirements and meet the personalized needs for lawn appearance and function in different scenarios. The second protective component 7 is closely connected to the cutting mechanism 6. While the lifting mechanism 8 adjusts the position of the cutting mechanism 6, it also adjusts the height of the second protective component 7 accordingly. Through proper adjustment, the second protective component 7 can always be kept in the optimal protective position, effectively preventing foreign objects from entering the cutting area regardless of the height of the cutting mechanism 6, preventing foreign objects from colliding with the high-speed rotating blades and causing danger, providing reliable safety for operators and the surrounding environment. The lifting mechanism 8 can precisely control the height of the cutting mechanism 6, placing the blades in the optimal cutting position, reducing cutting resistance, improving cutting efficiency, and enabling the lawnmower to complete the mowing task of a larger area in a shorter time. The lawnmower equipped with the lifting mechanism 8 allows operators to easily adjust the position of the cutting mechanism 6 and the second protective component 7 using simple control devices such as handles and buttons, greatly simplifying the operation process and improving the convenience and efficiency of operation.

[0047] The lifting mechanism 8 includes a lifting bracket, on which a motor cylinder is mounted. A waterproof component is connected to the bottom of the motor cylinder, and the other end of the waterproof component is sealed to the chassis of the cutting mechanism 6. A second protective component 7 is installed on the motor cylinder and rises and falls synchronously with the motor cylinder. The motor of the cutting mechanism 6 is installed inside the motor cylinder, and the motor output shaft extends below the chassis and is connected to a connecting component. The cutter head is fixed to the connecting component and rotates with the motor. Part of the structure of the second protective component 7 is located below the cutter head to provide protection for the cutting blades on the cutter head.
