Description

Technical Field

[0001] This invention relates to the field of garden tool technology, and in particular to an air-floating mowing device. Background Technology

[0002] The air-floating lawn mower includes a body, an operating lever, and a handle. One end of the operating lever is connected to the body, and the other end is connected to the handle. The user holds the handle and applies a pushing force to the operating lever, thereby enabling the air-floating lawn mower to mow different parts of the lawn.

[0003] The existing air-floating mowers have long operating rods that are fixed to the machine body, resulting in a large space occupied by the air-floating mowers, making it inconvenient for users to store and move them.

[0004] Therefore, there is an urgent need to design an air-floating mowing device to solve the problem of inconvenient storage and transfer of air-floating mowing devices. Summary of the Invention

[0074] Example 1

[0075] like Figure 1 As shown, this embodiment provides an air-floating lawn mower 100, which includes a body 4, an operating lever, a handle 1, and wheels 7. One end of the operating lever is connected to the body 4, and the other end of the operating lever is connected to the handle 1. The wheels 7 are located on the lower end face of the body 4. The user holds the handle 1 and applies a pushing force to the operating lever, thereby enabling the air-floating lawn mower 100 to perform lawn mowing operations on different locations of the lawn.

[0076] As a preferred option, such as Figure 1 and Figure 2 As shown, handle 1 is a ring handle, symmetrically arranged around the operating lever. Users prefer to stand still while using the air-floating mower 100, simultaneously swinging it from the mowed area to the unmowed area with both hands. The ring handle design allows users to easily grip it with both hands to swing the air-floating mower 100. The width of the ring handle is sufficient for simultaneous use by both hands, allowing users to grip both sides. In other embodiments, such as... Figure 3 As shown, the handle 1 can be in the shape of a long rod. The long rod handle is symmetrically arranged with the operating rod as the center line, which also makes it convenient for the user to hold the long rod handle with both hands to swing the air flotation mower 100.

[0077] As a preferred option, such as Figure 1 and Figure 2The machine body 4 includes a housing 41, a motor, and a cutting saw. The motor is located inside the housing 41, and the cutting saw is located at the lower part of the housing 41. The motor can drive the cutting saw to rotate, thereby realizing the cutting effect of the cutting saw on the lawn.

[0078] As a preferred option, such as Figure 1 and Figure 2 As shown, the handle 1 also includes a switch box 11 and connecting wires. The switch box 11 is mounted on the operating lever, and the motor is electrically connected to the switch box 11 via the connecting wires. The switch box 11 controls the motor's operation by driving and stopping it via the connecting wires. Furthermore, the air-floating mower 100 also includes a cable clip that secures the connecting wires to the operating lever. The switch box 11 also has an extension power cord for connecting to an AC power source to provide the power required for the motor's operation. The extension power cord has a coupling element for mating with a dedicated power cord plug to ensure the power cord is long enough for outdoor operation.

[0079] The existing air-floating mowing device 100 has a long operating lever that is fixed to the machine body 4, which results in the air-floating mowing device 100 occupying a large space, making it inconvenient for users to move the air-floating mowing device 100.

[0080] To solve the above problems, such as Figure 1 and Figure 2 As shown, the air-floating mower 100 also includes a handle 1, a long strip-shaped first push rod 2, a second push rod 3, and a first locking mechanism 5. The long strip-shaped first push rod 2 is fixedly connected to the handle 1, and the two ends of the second push rod 3 are pivotally connected to the first push rod 2 and the body 4, respectively. When the first push rod 2 and the second push rod 3 are rotated to a folded state relative to the body 4, the first locking mechanism 5 locks the first push rod 2 and the body 4. By folding the second push rod 3 relative to the body 4, folding the first push rod 2 relative to the second push rod 3, and locking the first push rod 2 and the body 4 with the first locking mechanism 5, the first push rod 2, the second push rod 3, and the body 4 are arranged compactly to form a module with a small footprint, which facilitates the storage of the air-floating mower 100 and makes it easy for users to move the compact and space-saving module.

[0081] As a preferred option, such as Figure 2 As shown, the first push rod 2 and the second push rod 3 are pivotally connected through the first pivot joint. The first distance L1 between the first locking mechanism 5 and the first pivot joint is greater than zero, so that the first push rod 2 can be held by the user in the section between the first locking mechanism 5 and the first pivot joint, which makes it convenient for the user to apply force to the first push rod 2 to transfer the folded air-floating mowing device 100.

[0082] As a preferred option, such as Figure 2As shown, when the air-floating lawnmower 100 is in the folded state, the projection of the handle 1 on the ground is outside the projection of the body 4 on the ground. In other words, the total length of the first push rod 2 and the handle 1 is relatively long and occupies a large weight, which causes the center of gravity of the air-floating lawnmower 100 to shift upward. This allows the weight of the handle 1 and the first push rod 2 to maintain a certain weight balance with the weight of the body 4 after the air-floating lawnmower 100 is folded and lifted, increasing the comfort of holding it when lifted.

[0083] As a preferred option, such as Figure 2 As shown, the first distance L1 between the first locking mechanism 5 and the first pivot joint is less than the second distance L2 between the first locking mechanism 5 and the handle 1. Because the first distance L1 is smaller, the range of distance variation between the projection of the user's grip position on the ground and the projection of the center of gravity of the folded air-floating mower 100 on the ground is small. This allows the user to hold the air-floating mower 100 stably, preventing the air-floating mower 100 from swaying left and right during transfer, and facilitating the smooth transfer of the folded air-floating mower 100. Specifically, the range of the first distance L1 between the first locking mechanism 5 and the first pivot joint and the second distance L2 between the first locking mechanism 5 and the handle 1 is 1:2 to 1:3. This ensures smooth transfer of the folded air-floating mower 100 and also ensures that the projection of the first push rod 2 on the ground mostly falls within the projection of the machine body 4 on the ground, preventing the first push rod 2 from extending too far out of the machine body 4 in the horizontal direction, thus facilitating the storage of the folded air-floating mower 100.

[0084] As a preferred option, such as Figure 1 and Figure 2 As shown, the second push rod 3 is U-shaped, which enables a stable connection between the U-shaped second push rod 3 and the machine body 4, facilitating the user to apply force to the handle 1 and effectively driving the air-floating mower 100. Specifically, the second push rod 3 and the machine body 4 have two second pivot joints 43, ensuring that the second push rod 3 rotates well relative to the machine body 4 without tilting. In other embodiments, the second pivot joints 43 between the second push rod 3 and the machine body 4 can also be three, four, or more. The more second pivot joints 43 are provided, the more stable the rotation of the second push rod 3 relative to the machine body 4.

[0085] As a preferred option, such as Figure 2 As shown, the second push rod 3 is pivotally connected to the body 4 at the middle position along the front-to-back direction. When the air-floating mower 100 is folded and the air-floating mower 100 is erected, it forms a vertical structure. Figure 2 In the state shown, the first pivot joint and the rear end of the body 4 jointly support the air-floating mowing device. Because the first pivot joint integrates the first push rod 2 and the second push rod 3, its structure is thick and strong, enabling it to provide relatively stable support for the air-floating mowing device 100. Furthermore, as... Figure 2As shown, the second push rod 3, the bottom surface of the housing 41, and the ground form a triangular structure. This triangular structure provides good stability and can stably support the air-floating mower 100, preventing it from tipping over. Furthermore, the contact between the first pivot point and the ground allows the handle 1 to be positioned high off the ground, thus preventing damage to the handle 1 and ensuring a good grip for the user. Figure 2 As shown, the first locking mechanism 5 is locked to the top of the body 4. Under the action of the gravity of the body 4, the second push rod 3 will tend to rotate counterclockwise. The second push rod 3 will tend to drive the first push rod 2 to rotate counterclockwise. Since the first locking mechanism 5 is locked to the top of the body 4, the top of the body 4 can prevent the first push rod 2 from rotating counterclockwise. The gravity of the body 4 will keep the first push rod 2, the second push rod 3 and the body 4 tightly locked at all times, preventing the first push rod 2, the second push rod 3 and the body 4 from loosening and preventing the air flotation mowing device 100 from tipping over when stored vertically.

[0086] As a preferred option, such as Figure 2 As shown, when the air-floating mower 100 is folded, the first pivot joint is located within the extended surface of the top surface of the body 4. The line connecting the first pivot joint and the rear end of the body 4 is perpendicular to the extended surface of the top surface of the body 4. The first pivot joint and the rear end of the body 4 are placed together on the ground, and the first push rod 2 extends in a direction perpendicular to the ground, thereby achieving upright storage of the air-floating mower 100. As a preferred embodiment, such as... Figure 1 As shown, when the air-floating mower 100 is mowing, the projection of the handle 1 on the ground is outside the projection of the body 4 on the ground. By utilizing the lever principle, the user can push the air-floating mower 100 to move on the ground by applying only a small force to the handle 1, thus achieving a better labor-saving effect.

[0087] As a preferred option, such as Figure 1 and Figure 2 As shown, when the first push rod 2 and the second push rod 3 are rotated to the folded state relative to the body 4, the distance between the first push rod 2 and the top of the body 4 is relatively small. Therefore, a simple first locking mechanism 5 can be used to lock the top of the body 4. Specifically, one part of the first locking mechanism 5 is located in the housing 41, and the other part is located in the first push rod 2. The quick assembly and disassembly of the two parts of the first locking mechanism 5 allows for the quick assembly and disassembly of the first push rod 2 from the housing 41. Specifically, as... Figure 2 and Figure 4 As shown, a portion of the first locking mechanism 5 is disposed on the top of the housing 41 or on the side of the housing 41 facing the first pivot, which facilitates quick assembly and disassembly of the first pivot and the housing 41.

[0088] Combination Figure 4 and Figure 5 The structure of the first locking mechanism 5 will be described as follows: Figure 4 and Figure 5 As shown, the first locking mechanism 5 includes a hook 51 and a first elastic element. The hook 51 and the first elastic element are mounted on the first push rod 2. A slot 411 is provided on the body 4. The first elastic element is used to engage the hook 51 in the slot 411, thereby achieving a secure lock between the hook 51 and the slot 411. When unlocking is required, the user squeezes the hook 51, which compresses and deforms the first elastic element, thereby disengaging the hook 51 from the slot 411 and unlocking the hook 51 from the slot 411. Specifically, the first elastic element can be a spring or a rubber pad with good elastic deformation.

[0089] Specifically, such as Figure 5 The hook 15 includes a hook body 511 and a pivot shaft 512. The pivot shaft 512 is connected to the hook body 511 and pivotally connected to the first push rod 2. A first elastic element is disposed between the hook portion of the hook body 511 and the first push rod 2. The first elastic element can achieve a tight lock between the hook portion and the slot 411. Specifically, as... Figure 5 As shown, the two ends of the pivot shaft 512 extend to both sides of the hook body 511 in the width direction, which can realize the stable pivot connection between the pivot shaft 512 and the first push rod 2 and prevent the hook 15 from falling off the first push rod 2.

[0090] As a preferred option, such as Figure 1 As shown, the air-floating mower 100 also includes a second locking mechanism 6. The second locking mechanism 6 is used to lock the first push rod 2 and the second push rod 3, which are at a preset angle. When the air-floating mower 100 is mowing, the second locking mechanism 6 can ensure that the first push rod 2 and the second push rod 3 always remain collinear to form a longer operating lever, making it easier for the user to push the air-floating mower 100 with less force. When the air-floating mower 100 is folded, by locking the first push rod 2 and the second push rod 3, which are set at an angle, it can prevent the first push rod 2 and the second push rod 3 from spreading out under the action of external force. The first locking mechanism 5 and the second locking mechanism 6 form a double lock to ensure that the air-floating mower 100 always maintains a good folded state.

[0091] Combination Figures 6-9 The structure of the second locking mechanism 6 will be described as follows: Figures 6-9 As shown, the second locking mechanism 6 includes a rotating member 61, a positioning member 62, and a trigger member 63. The rotating member 61 is fixed to the first push rod 2, and the positioning member 62 is fixedly connected to the second push rod 3. The rotating member 61 is pivotally connected to the positioning member 62 and can be locked with the positioning member 62. The trigger member 63 is activated to unlock the rotating member 61 and the positioning member 62. The user can quickly lock and unlock the first push rod 2 and the second push rod 3 through a simple triggering action, which is convenient for the user's operation.

[0092] Specifically, such as Figures 6-9 As shown, the rotating component 61 includes a first clamping arm 611 and a second clamping arm 612. Both the first clamping arm 611 and the second clamping arm 612 are fixed to the first push rod 2. An accommodating space 613 is formed between the first clamping arm 611 and the second clamping arm 612. A portion of the positioning component 62 is located in the accommodating space 613. The second locking mechanism 6 includes a first state and a second state. When the second locking mechanism 6 is in the first state, the trigger 63 is at the first angle, and the positioning component 62 can rotate between the first clamping arm 611 and the second clamping arm 612. When the second locking mechanism 6 is at the second angle, the first clamping arm 611 and the second clamping arm 612 together clamp the positioning component 62. The second locking mechanism 6 has a simple structure and is easy to manufacture.

[0093] Specifically, such as Figure 7 and Figure 8 As shown, the first clamping arm 611 has a through hole 6111, and the second clamping arm 612 includes a clamping arm body 6121 and a support rod 6122 connected to each other. The first clamping arm 611 and the second clamping arm 612 together form an accommodating space 613. The support rod 6122 passes through the through hole 6111. The trigger 63 is pivotally connected to the upper end of the support rod 6122. When the trigger 63 is flipped to be directly opposite and parallel to the first clamping arm 611, since the lower end of the trigger 63 is a cam, the larger diameter part of the cam abuts against the first clamping arm 611, reducing the distance between the first clamping arm 611 and the second clamping arm 612. The first clamping arm 611 and the second clamping arm 612 jointly clamp the positioning member 62, thereby locking the relative position of the first push rod 2 and the second push rod 3. Figure 6 When the trigger 63 rotates to be collinear with the support rod 6122, the smaller diameter portion of the cam in the trigger 63 contacts the first clamping arm 611. The first clamping arm 611 resets, and the distance between the first clamping arm 611 and the second clamping arm 612 returns to their natural distance. The first clamping arm 611 and the second clamping arm 612 release the positioning member 62, thereby unlocking the first push rod 2 and the second push rod 3, allowing the user to adjust the angle between the first push rod 2 and the second push rod 3. In summary, the user can quickly lock and unlock the first push rod 2 and the second push rod 3 by simply rotating the trigger 63, making the operation simple and convenient. In other embodiments, the second locking mechanism 6 may also include a fixing member such as a bolt, which enables quick assembly and disassembly of the first clamping arm 611 and the second clamping arm 612, and also enables quick locking and unlocking of the first push rod 2 and the second push rod 3.

[0094] As a preferred option, such as Figure 7 and Figure 8As shown, the positioning member 62 has multiple circumferentially distributed first receiving grooves 621, the first clamping arm 611 has a first protrusion, and the clamping arm body 6121 has a second protrusion 61211. When the rotating member 61 is rotated relative to the positioning member 62 to a predetermined position, the first protrusion and the second protrusion 61211 engage with the corresponding first receiving grooves 621. Then, the trigger member 63 locks the first clamping arm 611 and the second clamping arm 612. Through the cooperation of the first protrusion and the second protrusion 61211 with the corresponding first receiving grooves 621, the relative rotation between the positioning member 62 and the rotating member 61 can be further prevented, achieving a stable lock between the positioning member 62 and the rotating member 61. As a preferred embodiment, the outer contours of the first protrusion and the second protrusion 61211 are arc-shaped, thereby avoiding damage to the positioning member 62 by the first protrusion and the second protrusion 61211 and ensuring a longer service life for the rotating member 61 and the positioning member 62. As a preferred embodiment, the inner circumferential surfaces of the first clamping arm 611 and the second clamping arm 612 are provided with reinforcing ribs, which can improve the overall strength and hardness of the first clamping arm 611 and the second clamping arm 612 and prevent the first clamping arm 611 and the second clamping arm 612 from being damaged during long-term stress.

[0095] As a preferred option, such as Figure 10 and Figure 11 As shown, the second push rod 3 is pivotally connected to the body 4 via the second pivot joint 43. The second pivot joint 43 is provided with a limiting groove 431 for limiting the rotation of the second push rod 3. The limiting groove 431 includes at least two limiting walls, which are arranged along the forward direction of the air-floating mower 100 to limit the rotation angle of the second push rod 3 relative to the body 4. This allows the user to quickly determine that the second push rod 3 is in the correct position and facilitates the user to quickly switch between different states of the air-floating mower 100.

[0096] Specifically, the two limiting walls include a first limiting wall 432 disposed on one side of the limiting groove 431 and a second limiting wall 433 opposite to the first limiting wall 432. The first limiting wall 432 is disposed at the front end of the limiting groove 431 to close the front end of the limiting groove 431, thereby limiting the angle at which the second push rod 3 rotates forward relative to the body 4.

[0097] As a preferred option, such as Figure 11As shown, one side wall of the limiting groove 431 protrudes along the axis of the pivot shaft of the second pivot 43 to form a protrusion. The second limiting wall 433 is part of the outer side wall of the protrusion. The distance between the protrusion and the other side wall of the limiting groove 431 is greater than the diameter of the second push rod 3. The second push rod 3 can move relative to the machine body 4 along the axis of the pivot shaft of the second pivot 43 so that the second push rod 3 can move into the gap between the protrusion and the other side wall of the limiting groove 431. At this time, the second push rod 3 can be placed horizontally. For example, when the machine body 4 is placed on the ground, the second push rod 3 and the first push rod 2 are both placed horizontally on the ground. This can avoid the second push rod 3 interfering with the user and facilitate the user's maintenance of the air flotation mowing device 100.

[0098] Example 2

[0099] This embodiment provides an air-floating mowing device 100, the structure of which is basically the same as that of the air-floating mowing device 100 in Embodiment 1. The main difference between the two is that the structures of the first locking mechanism 5 and the second locking mechanism 6 are different.

[0100] Specifically, such as Figure 12 As shown, the first locking mechanism 5 in this embodiment includes a first locking member 53 and a second locking member 54. The first locking member 53 is disposed on the first push rod 2, and the second locking member 54 is located on the body 4. The second locking member 54 has a first position and a second position relative to the body 4. When the second locking member 54 is in the first position, the first locking member 53 and the second locking member 54 are locked; when the second locking member 54 is in the second position, the first locking member 53 and the second locking member 54 are unlocked. By switching the second locking member 54 between the first position and the second position, the first locking member 53 and the second locking member 54 can be quickly locked and unlocked.

[0101] Specifically, such as Figure 12As shown, the first locking member 53 includes a connecting rod 531 and a limiting block 532, and the second locking member 54 includes a fixed base 541 and a sliding plate 542. The fixed base 541 is mounted on the body 4, and the sliding plate 542 is inserted into the fixed base 541 and can switch between a first position and a second position. The sliding plate 542 has a connected insertion hole 5421 and an elongated hole 5422. When the sliding plate 542 is in the second position, the limiting block 532 can be inserted into the insertion hole 5421; when the sliding plate 542 switches from the second position to the first position, the connecting rod 531 can slide from the insertion hole 5421 to the elongated hole 5422, and the elongated hole 5422 can prevent the limiting block 532 from disengaging. The user can quickly lock and unlock the first locking member 53 and the second locking member 54 by a simple pulling action, which is convenient for the user. As a preferred embodiment, the mounting base 541 has a horizontally oriented slot, into which the sliding plate 542 is inserted, ensuring that the sliding plate 542 slides smoothly in the horizontal direction without separating from the mounting base 541. Specifically, the sliding plate 542 is interference-fitted with the side wall of the slot to prevent the sliding plate 542 from falling off the mounting base 541. As a preferred embodiment, the free end of the sliding plate 542 is provided with a gripping part, which facilitates the user's gripping action on the sliding plate 542.

[0102] Combination Figure 13 The structure of the second locking mechanism 6 in this embodiment will be described as follows: Figure 13 As shown, the positioning member 62 has a first receiving groove 621, and the rotating member 61 has a second receiving groove 614. The rotating member 61 is inserted into the second receiving groove 614. The trigger member 63 is disposed in the first receiving groove 621 and the second receiving groove 614. The outer periphery of the trigger member 63 is provided with a plurality of spaced first teeth 631, and the bottom surface of the first receiving groove 621 is provided with a plurality of spaced second teeth 622 along the circumferential direction. The second locking mechanism 6 also includes a second elastic member 64, which can resist the trigger member 63, so that when the second elastic member 64 is not under force, the first teeth 631 are inserted between two adjacent second teeth 622. By pressing the trigger member 63, the user can compress the second elastic member 64, and the first teeth 631 and the second teeth 622 separate from each other along the axial direction. At this time, the relative position between the positioning member 62 and the rotating member 61 can be adjusted, thereby adjusting the angle of the first push rod 2 where the positioning member 63 is located relative to the second push rod 3. With the above structure, the user can quickly unlock and lock the positioning member 62 and the rotating member 61 by simply pressing the trigger member 63, which is convenient for the user to operate with one hand.

[0103] As a preferred option, such as Figure 13As shown, a guide member 615 is provided in the second receiving groove 614. The first tooth 631 cooperates with the guide member 615 to allow the trigger member 63 to slide along the depth direction of the second receiving groove 614, ensuring that the trigger member 63 has a good squeezing operation on the second elastic member 64. Specifically, the guide member 615 includes a plurality of guide plates distributed circumferentially along the second receiving groove 614, and a guide groove 616 is formed between adjacent guide plates. The first tooth 631 can be inserted into the guide groove 616 and slide, thereby enabling the trigger member 63 to slide along the depth direction of the second receiving groove 614.

[0104] As a preferred option, such as Figure 13 As shown, the rotating member 61 has a locking interface 617, and the trigger member 63 has a hook 632. The hook 632 extends from the inside of the second receiving groove 614 to the outside of the second receiving groove 614. When the second elastic member 64 enables the first tooth 631 to be inserted between two adjacent second teeth 622, the hook 632 is locked with the outer wall of the rotating member 61, thereby preventing the trigger member 63 from separating from the rotating member 61.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
