Description

Technical Field

[0001] The utility model belongs to the technical field of gardening, and in particular relates to a balancing structure of a lawn mower base. Background Art

[0002] With the acceleration of urbanization and rising demands for a better living environment, landscaping has become an integral part of urban development. As a crucial tool for garden maintenance, lawn mowers play a key role in tasks like lawn mowing. Traditional lawn mower designs often focus on improving cutting efficiency and ease of use. However, in practice, due to the complex and changing working environment, especially when encountering uneven surfaces or hard objects, this can lead to increased vibration, compromising operational accuracy and increasing the risk of equipment damage.

[0003] Existing lawn mower chassis structures are generally simple, typically consisting of a single-layer blade mount and a basic support frame. While this structure can meet basic mowing requirements, it is significantly inadequate in reducing vibration during operation and enhancing overall machine stability. In particular, when a lawn mower encounters obstacles or significant terrain changes while operating at high speed, the intense vibration not only reduces efficiency but can also cause injury to the operator. Furthermore, mechanical components exposed to prolonged high-amplitude vibrations are prone to accelerated wear, shortening the equipment's service life.

[0004] Chinese patent publication number CN208509607U discloses an environmentally friendly garden lawn mower, comprising a base body, wherein two symmetrical sliding bars are fixedly connected to the upper surface of the base body, and two symmetrical sliders are placed above the base body. A sliding hole is provided in the middle of the upper surface of each slider to match the sliding bar, and each slider is sleeved onto the outer surface of the sliding bar through the sliding hole. A buffer spring is sleeved onto the outer surface of each slider, and a support plate is fixedly connected to the side of the two sliders adjacent to each other, and a motor is fixedly connected to the bottom surface of the support plate. The above device reduces the vibration of the lawn mower through two symmetrical sliding bars and the buffer springs on the sliding bars. However, the shock absorption effect is only good at the position where the sliding bars are located. Since the sliding bars and shock absorption springs are not provided in the remaining parts, the shock absorption effect is poor, resulting in poor balance of the lawn mower. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is that in the above-mentioned prior art, the lawn mower has poor shock absorption effect and low balance stability.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A lawn mower base balancing structure includes a cutting blade, a buffer and a balancing base; the cutting blade includes a first cutting blade and a second cutting blade, the first cutting blade is located at the bottom, the second cutting blade is located above the first cutting blade, the balancing base is located above the second cutting blade, and the buffer passes through the first cutting blade, the second cutting blade and the balancing base.

[0008] By adopting the above technical solution, a balancing base is placed between the first and second cutting blades, and a buffer is used throughout the entire structure to effectively disperse and absorb vibrations generated during operation. This reduces overall wobbling of the mower, thereby improving its operational stability. The buffer design helps absorb impact from the ground, especially when encountering uneven terrain or hard objects. This significantly reduces the vibration transmitted to the handle and even the user, making prolonged operation more comfortable. By reducing unnecessary movement and vibration, this design indirectly improves the safety of the device. For the operator, this means a lower risk of accidental injury. Continuous and intense vibration can cause wear and tear on mechanical equipment, particularly on critical components such as the motor and bearings. By reducing vibration, this new balancing structure helps slow the aging of these components, thereby extending the overall lifespan of the mower. More stable operation means the mower will more closely follow its intended path, providing more consistent mowing results. Furthermore, reducing pauses caused by vibration makes the mowing process smoother and more efficient.

[0009] Furthermore, the head end of the first cutting blade and the head end of the second cutting blade are connected together through an isolating member, and the isolating member includes a connecting rod, a locking nut and a socket, the socket is welded to the connecting rod, and the bottom of the connecting rod is provided with a thread, the locking nut is fixed to the bottom of the connecting rod, the second cutting blade is clamped between the socket and the top of the connecting rod, and the locking nut is located below the first cutting blade.

[0010] By adopting the above technical solution, a combination of a connecting rod, a locking nut, and a socket can be used to provide a sturdy and reliable connection method. In particular, when the socket is welded to the connecting rod, the stability of the overall structure is further enhanced, making the connection between the two layers of cutting blades more secure. Using a locking nut to fix the cutting blade means that if the blade needs to be repaired or replaced, it can be easily disassembled by simply loosening the nut. This method simplifies the maintenance process and reduces maintenance costs. Since the second cutting blade is clamped between the socket and the top of the connecting rod, this design can ensure that the relative position between the two blades is accurate, thereby ensuring the accuracy and stability of the lawn mower during operation. The presence of the isolation member can isolate the impact force transmitted from the ground to a certain extent, reduce the vibration directly transmitted to the upper components (such as the balancing base), and help maintain the stability of the entire lawn mower operation.

[0011] Furthermore, the buffer component includes a receiving surface, a transition surface, a connecting end and a locking component, the connecting end extends outward to form the receiving surface, the receiving surface extends downward to form the transition surface, the transition surface box extends inward to form a second receiving surface, the second receiving surface extends downward to form a second connecting end, and the locking component is provided on the second connecting end; the connecting end passes through the buffer component, the receiving surface abuts the bottom of the buffer component, the transition surface is located between the first cutting blade and the buffer component, the second receiving surface abuts the top of the first cutting blade, the second connecting end passes through the first cutting blade, and the locking component is clamped at the bottom of the first cutting blade.

[0012] By adopting the above-mentioned technical solution, the multi-layered design of the buffer, including the receiving surface, transition surface, and second receiving surface, can effectively disperse and absorb vibrations from the ground and the cutting blade during operation. This structure helps reduce the vibrations transmitted to the upper structure of the lawn mower and the operator's hands, providing a smoother operating experience. The buffer runs through the entire assembly through the connecting end, and the locking piece is clamped at the bottom of the first cutting blade to ensure a tight connection between the various components. This not only strengthens the stability of the overall structure, but also reduces the potential risk of failure due to looseness. By effectively reducing the direct impact force between mechanical components, the buffer helps slow the wear rate of key parts such as bearings and gears, thereby indirectly extending the overall service life of the lawn mower. The stable operating state means that the lawn mower can complete its tasks more smoothly, avoiding time wasted due to frequent pauses or adjustments.

[0013] Furthermore, the buffer is entirely made of rubber.

[0014] By adopting the above technical solution, the rubber material has excellent elasticity and shock absorption properties, which can effectively absorb and disperse mechanical vibrations, reducing the vibration caused by uneven ground or obstacles during operation, thereby improving operational smoothness. High-quality rubber materials generally have high wear resistance and can maintain good physical properties after long-term use. This means that the buffer can withstand repeated compression and extension without damage, extending its service life. Rubber is highly resistant to common chemicals such as water and oil and is not easily corroded. This is particularly important for lawn mowers frequently exposed to outdoor environments, as it can prevent component failures caused by problems such as rust. Compared to metal or other hard materials, rubber is lighter, which helps to reduce the total weight of the entire lawn mower base structure. This not only facilitates handling but also has a positive effect on reducing energy consumption.

[0015] Furthermore, a shock-absorbing seat is provided at the bottom of the second cutting blade, and the shock-absorbing seat includes a positioning ring that passes through the second cutting blade. A shock-absorbing surface extends outward from the bottom of the positioning ring, and the shock-absorbing surface abuts against the second cutting blade. A shock-absorbing rubber is also provided at the bottom of the shock-absorbing surface, and the shock-absorbing rubber abuts against the top of the first cutting blade.

[0016] By adopting this technical solution, the shock mount design incorporates an additional shock-absorbing layer. The damping rubber, in particular, effectively absorbs and disperses impact forces from the ground. This helps further reduce vibration transmitted to the mower's superstructure and the operator's hands, providing a smoother operating experience. The locating ring runs through the second cutting blade and tightly engages it, ensuring a secure connection between the shock mount and the cutting blade. This design not only enhances overall structural rigidity but also reduces the risk of failure due to loose components. The use of damping rubber mitigates direct impact on mechanical components such as bearings and gears, thereby slowing wear on these critical parts. This helps extend the overall life of the mower and reduces maintenance costs.

[0017] Furthermore, three buffer members are provided.

[0018] By adopting the above technical solution and setting up three buffers, more uniform support points can be formed between the first cutting blade, the second cutting blade, and the balancing base. This can better disperse the pressure and vibration generated from the ground and during operation, ensure that the entire structure is balanced, and avoid damage caused by local overloads. The design of multiple buffers increases the number of contact points of the structure, thereby improving the stability and anti-tilt ability of the entire machine. Especially when operating on uneven or sloping ground, multi-point support can more effectively maintain the horizontal posture of the lawn mower and reduce the risk of rollover. Each buffer can work independently to absorb vibrations, and the synergistic effect of the three can significantly improve the vibration reduction efficiency. This is very beneficial for reducing the vibration amplitude during operation, which not only improves the operating comfort, but also reduces the impact on internal mechanical components and extends the service life.

[0019] The utility model has the following beneficial effects:

[0020] 1. By providing three buffers between the first and second cutting blades and the balancing base, this utility model can more effectively disperse and absorb impact forces from the ground and vibrations generated during operation. The multi-point support system not only reduces the amplitude of vibration transmitted to the operator's hands, but also reduces the impact on internal mechanical components, thereby extending the overall service life of the lawn mower and improving user comfort.

[0021] 2. This utility model uses three buffers evenly distributed in the base structure to form a more stable support system, which helps improve the stability of the lawn mower on uneven terrain or slopes and reduce the risk of rollover. When encountering local obstacles or complex terrain changes, the multi-point support can better maintain the machine's level posture, ensure smooth operation, and improve operating efficiency and safety.

[0022] 3. The balancing base and vibration-damping base of this utility model help achieve a balanced weight distribution among the various parts of the bottom of the lawn mower, making the center of gravity position of the entire machine more ideal, improving the operational flexibility and response speed of the lawn mower, and can effectively cope with the challenges of various working environments. Whether it is flat ground or undulating grass, it can ensure efficient lawn mowing quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Working principle: The double-layer design of the first cutting blade 11 and the second cutting blade 12 provides a more uniform distribution of cutting force, reducing the violent vibration of a single blade due to impact. The second cutting blade 12 is located above the first cutting blade 11, assisting in cutting and providing additional support, which helps to disperse the vibration during the cutting process. The isolation member 4 composed of the connecting rod 41, the locking nut 42 and the receiving seat 43 ensures a firm connection between the first cutting blade 11 and the second cutting blade 12, and can absorb part of the impact caused by uneven ground. The receiving seat 43 is welded to the connecting rod 41, which further enhances the stability of the connection and reduces In order to prevent additional vibration caused by looseness, three buffers 2 are evenly distributed in the base structure.
