Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, and more specifically, to a lawnmower vibration damping mechanism. Background Technology

[0002] A lawnmower is a gardening tool or agricultural machine used to trim lawns, grasslands, and other vegetation. It is widely used in home gardens, parks, golf courses, farmland, and other settings. A lawnmower mainly consists of an engine, transmission system, blades, wheels, a grass collection box, and a grass discharge system. When the lawnmower is working, the driving engine transmits the driving force to the blade spindle through a belt and gears, causing the blades to rotate at high speed. Centrifugal force is used to cut the grass blades. During the cutting process, the grass clippings are drawn into the grass collection box by the airflow and discharged through the side outlet. Since the engine generates vibration when it is working, it is necessary to perform vibration reduction operations.

[0003] In related technologies, during the use of lawnmowers, the lawnmower is generally moved by a pusher frame to cut the grass at the mowing work position.

[0004] However, during the current use of lawnmowers, the vibration force of the lawnmower is transmitted to the push frame. Since the operator mainly uses the push frame to push the lawnmower, when cutting large areas of grass, the operator's arm is easily numb due to the vibration force of the push frame, or even the operator loses their hand, which affects the vibration reduction effect and safety of the lawnmower.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4This utility model provides a technical solution: a lawnmower vibration damping mechanism, including a lawnmower 1 and a push vibration damping mechanism. The lawnmower 1 is equipped with casters 2 on all four sides, and a push frame 3 is installed on the right side of the top of the lawnmower 1. The push frame 3 can perform hand-held vibration damping work on the hand-held part of the push frame 3, reducing the vibration impact of the push frame 3 on the operator's arm when the lawnmower 1 is working, and avoiding the vibration force of the push frame 3 during use, which may cause the operator's arm to become numb or even drop their hand. Therefore, the vibration damping effect and safety of the push frame 3 and the lawnmower 1 are improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the vibration damping mechanism includes a vibration damping seat 4, which is movably connected to both sides of the push frame 3. Vibration damping openings 5 ​​are provided on both sides of the inner wall of the vibration damping seat 4. A sleeve 6 is fixedly connected to the outer side of the vibration damping seat 4. A damper 7 is installed inside the sleeve 6, and a spring 8 is sleeved on the outer side of the damper 7. A vibration damping docking mechanism is fixedly connected to the left and right sides of the vibration damping seat 4. The damper 7, in conjunction with the spring 8 and the sleeve 6, provides elastic support between the vibration damping seat 4 and the push frame 3. Since the vibration damping seat 4 docks to form a vibration damping cylinder, a vibration damping medium is formed on the outer side of the push frame 3. When using the push frame 3, the lawnmower 1 can be pushed by holding the vibration damping seat 4. At this time, the damper 7, in conjunction with the spring 8 and the sleeve 6, damps the vibration of the push frame 3. The vibration damping docking mechanism absorbs power through telescopic expansion and contraction. It includes a docking seat 9, a docking plate 10, a docking interface 11, and a docking post 12. The docking seat 9 is fixedly connected to the left and right sides of the vibration damping seat 4. The docking plate 10 is movably connected to the top of the docking seat 9. The inner side of the docking plate 10 is fixedly connected to the outer side of the vibration damping seat 4. The docking interface 11 is located on the outer side of the top of the docking plate 10. The docking post 12 is movably connected to the inside of the docking interface 11. The bottom of the docking post 12 is fixedly connected to the top of the docking seat 9. This mechanism allows for the docking of vibration damping seats 4 with anti-displacement media, facilitating installation and docking operations for the vibration damping seats 4. It avoids difficulties in docking and preventing displacement during use of the vibration damping seats 4, thus improving the docking convenience of the vibration damping seats 4.

[0032] Reference Figures 2-4 In a preferred embodiment, a slot 13 located inside the interface 11 is provided on the top of the docking plate 10. The slot 13 is movably connected to a locking seat 14 that engages with the docking seat 9. The docking seat 9 and the docking plate 10 can be used to lock and stabilize the vibration damping seat 4, avoiding the situation where the docking plate 10 and the docking seat 9 are difficult to lock and stabilize during use. Therefore, the docking stability and convenience of the docking plate 10 and the docking seat 9 are improved. The top of the docking seat 9 is provided with a locking cavity 15 that communicates with the slot 13. The bottom of the locking seat 14 is located inside the locking cavity 15, which can provide space for the locking seat 14 to apply locking force between the docking seat 9 and the docking plate 10, thus improving the locking effect of the locking seat 14.

[0033] Reference Figures 2-4 In a preferred embodiment, by providing an movable opening 16 on the inner side of the top of the docking seat 9, and the outer side of the movable opening 16 communicating with the inner side of the card cavity 15, space can be provided for the card seat 14 to move out of the card cavity 15, thus improving the ease of installation and disassembly of the card seat 14. A magnetic plate 17 is embedded and connected to the outer side of the card seat 14, and magnetic suction plates 18 magnetically connected to the magnetic plate 17 are embedded and connected to the outer side of the card opening 13 and the inner wall of the card cavity 15, which can perform magnetic suction positioning between the card seat 14 and the card cavity 15, thus improving the working stability of the card seat 14.

[0034] Reference Figures 2-4 In a preferred embodiment, by movably connecting movable frames 19 to both sides of the top of the vibration damping seat 4, and by fixing movable plates 20 to both sides of the bottom of the movable frames 19, and by fixing the bottom of the movable plates 20 to the top of the card holder 14, a medium can be provided for the user to move the card holders 14 on both sides of the vibration damping seat 4 synchronously, thus improving the ease of movement of the card holder 14. Fixing holes 21 are opened on the outer sides of the top of the docking seat 9 and the docking plate 10, and fixing bolts 22 are movably connected inside the fixing holes 21, which can provide a medium for the user to fix the docking seat 9 and the docking plate 10, thus improving the ease of fixing the docking seat 9 and the docking plate 10.

[0035] Specifically, the working process or principle of this lawnmower vibration damping mechanism is as follows: During use, the two sets of damping seats 4 are moved to the top and bottom of the push frame 3 respectively. The docking seat 9 and docking plate 10 then align the docking post 12 with the docking interface 11. The damping seats 4 are then moved inwards, allowing the docking post 12 to pass through the docking interface 11 and through the docking plate 10, thus ensuring proper installation and anti-misalignment between the damping seats 4. Simultaneously, the locking seat 14 enters the docking seat 9 through the movable opening 16 and aligns with the locking cavity 15, preparing for the subsequent entry of the locking seat 14 into the locking cavity 15. Preparation is complete. Then, the movable frame 19, in conjunction with the movable plate 20, moves the card holder 14 outwards, causing it to enter the card cavity 15. This allows the card holder 14 and the card cavity 15 to connect and stabilize the vibration damping seat 4 via the docking seat 9 and the docking plate 10. Simultaneously, the magnetic plate 17 moves with the card holder 14 and contacts the magnetic suction plate 18, magnetically positioning the card holder 14 and the card cavity 15. Finally, the fixing bolt 22, in conjunction with the fixing port, secures the docking plate 10 and the docking seat 9, ensuring the docking seat 9 is properly engaged. The mating plate 10 is used to fix the vibration damping seats 4 together, ensuring the stability of the vibration damping seats 4 during operation. As the vibration damping seats 4 are mated to form a vibration damping cylinder on the outside of the push frame 3, the anti-slip pad on the inside of the damper 7 contacts the surface of the push frame 3, providing anti-slip contact between the damper 7 and the push frame 3. When the operator pushes the lawnmower 1 through the push frame 3, the push frame 3 can be used by holding the vibration damping seat 4. During this process, when the vibration force of the lawnmower 1 is transmitted to the push frame 3, the spring 8 is compressed or stretched under the influence of the vibration force, converting mechanical kinetic energy into... The elastic potential energy slows down the speed and intensity of vibration transmission. When the vibration force weakens, the spring 8 releases potential energy. At the same time, the piston inside the damper 7 moves, generating viscous resistance, which converts the vibration kinetic energy into heat energy and dissipates it. This can suppress the reciprocating oscillation of the spring 8 and avoid secondary vibration caused by the instantaneous rebound of energy. The spring 8 works with the damper 7 to provide elastic buffering, absorbing and dissipating the vibration force transmitted to the push frame 3 when the lawnmower 1 is working, reducing the vibration force of the push frame 3 on the user's arm, so that the staff can use the push frame 3 to push the lawnmower 1 for lawn mowing work for a long time.

[0036] It should be noted that the lawnmower 1, the moving wheels 2, and the pusher 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition, and principles are clear to those skilled in the art, so they will not be described in detail here.
