Description

Technical Field

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

[0002] With continuous economic development, people have increasingly higher requirements for urban planning and construction. In urban planning, to beautify the environment and purify the air, lawns and green spaces are often planted along roadsides or in parks. After planting, they need to be regularly trimmed to maintain good growth. To improve trimming efficiency, air-floating mowers are usually used. After use, air-floating mowers need to be stored and stored. However, storing air-floating mowers usually requires a large storage area, making storage difficult or causing instability during storage, potentially leading to damage from tipping over. Summary of the Invention

[0003] Based on this, the present invention proposes an air-floating mowing device that can reduce the difficulty of storage and tidiness, and has good stability during storage and tidiness, making it less prone to tipping over.

[0004] Air-floating lawn mowers, used for cutting lawns, include:

[0005] The machine assembly includes a motor, an impeller, a cutting component, and a first support. The machine assembly comprises an open cavity in which the motor, impeller, and cutting component are housed. The cutting component is connected to the impeller, and the impeller is connected to the motor. The motor drives the impeller to rotate, generating an airflow that suspends the air-floating mower and synchronously rotates the cutting component to cut the lawn. Along the forward direction of the air-floating mower, the first support is located at the rear end of the machine assembly.

[0006] An operating assembly includes a first operating member and a second operating member. The first operating member is rotatably connected to the body assembly about a first axis, and the second operating member is rotatably connected to the first operating member about a second axis parallel to the first axis. A second support portion is provided on the first operating member and / or the second operating member.

[0007] The air-floating mowing device has a stowed state, which includes a horizontal stowed state and an upright stowed state. In the upright stowed state, the extension direction of the second operating member is substantially parallel to the direction from the front end of the body assembly to the rear end, and the second support part is located at the outermost end of the operating assembly along the extension direction of the second operating member, so that the air-floating mowing device can be supported on the bearing surface by the first support part and the second support part, and the projection point of the center of gravity of the air-floating mowing device on the bearing surface is located between the first support part and the second support part, so that the air-floating mowing device is kept in the upright stowed state.

[0008] In one embodiment, in the upright storage state, the second support portion is flush with the first support portion, and the plane in which the two are located is parallel to the bearing surface.

[0021] In one embodiment, the second latching part is a first latching block extending outward from the main body of the second operating member, and the first latching part is a latching slot disposed on the rear side of the body assembly. In the upright storage state, the first latching block is latched into the latching slot.

[0022] In one embodiment, the body assembly includes a housing, the cavity is provided inside the housing, and the slot is disposed on the rear side of the housing;

The slot is located on the rear side of the motor housing, and the rear side of the housing has a notch. In the upright storage state, the first locking block passing through the notch is engaged with the slot.

[0024] In one embodiment, the second operating member further includes a second locking block extending outward from the main body, and the first locking block and the second locking block are arranged at intervals along the axial direction of the second operating member;

[0025] The body component is provided with a supporting surface;

[0026] When the first card block is inserted into the card slot, the second card block abuts against the abutting surface to prevent the first card block from dislodging from the card slot.

[0027] In one embodiment, the first operating member includes a first rod and a second rod, the first rod being rotatably connected to one side of the body assembly, the second rod being rotatably connected to the other side of the body assembly, the rotatable connection position of the first operating member and the second operating member being located between the first rod and the second rod, and the second support portion being located between the first rod and the second rod.

[0028] In one embodiment, a limiting groove is provided at the connection between the body assembly and the first operating member to limit the rotation of the first operating member. The limiting groove includes at least two limiting walls, which are arranged along the forward direction to limit the rotation angle of the first operating member relative to the body assembly.

[0029] In one embodiment, at least one of the connection points between the body assembly and the first rod, and the connection points between the body assembly and the second rod, is provided with the limiting groove.

[0030] In one embodiment, the two limiting walls include a first limiting wall disposed on one side of the limiting groove and a second limiting wall opposite to the first limiting wall, wherein...

[0031] The first limiting wall is disposed at the front end of the limiting groove to close the front end of the limiting groove, thereby limiting the angle at which the first rod and / or the second rod rotates forward relative to the body assembly.

[0032] In one embodiment, one sidewall of the limiting groove protrudes along the direction of the first axis to form a protrusion, the second limiting wall is part of the outer sidewall of the protrusion, and the distance between the protrusion and the other sidewall of the limiting groove is greater than the diameter of the first rod and / or the second rod.

[0033] In one embodiment, both the first rod and the second rod are movable relative to the body assembly along the first axis to be located between the corresponding first limiting wall and the second limiting wall, or to enter between the corresponding protrusion and the other side wall.

[0034] In one embodiment, the first operating member includes a third rod located between the first rod and the second rod, one end of the first rod being rotatably connected to the body assembly and the other end being connected to the third rod, and one end of the second rod being rotatably connected to the body assembly and the other end being connected to the third rod, and the second operating member being rotatably connected to the third rod.

[0035] In one embodiment, the air-floating mowing device has an operating state, wherein the first operating member rotates about the first axis, and the second operating member rotates about the second axis to switch between the operating state and the storage state; the angle between the first operating member and the second operating member in the operating state is 180 degrees.

[0037] In one embodiment, the second operating member includes a first clamping portion and a second clamping portion, and a portion of the upper part of the first operating member is located between the first clamping portion and the second clamping portion. In the working state, the first clamping portion and the second clamping portion clamp the portion of the first operating member to restrict the relative rotation between the second operating member and the first operating member.

[0038] In one embodiment, a connecting sleeve is fitted on a portion of the first operating member. The connecting sleeve is located between the first clamping portion and the second clamping portion. A limiting portion protrudes outward from the outer peripheral surface of the connecting sleeve, and a boss protrudes from the inner peripheral surface of the first clamping portion and / or the second clamping portion.

[0039] In the operating state, the boss abuts against the limiting part; when the second operating member rotates to a position other than the operating state, the boss separates from the limiting part.

[0041] The aforementioned air-floating mower includes a first support component in its body assembly, and a first operating component and / or a second operating component including a second support component. In its upright storage state, the air-floating mower can be supported on a bearing surface by the first and second support components, achieving upright storage. In this state, the rear end of the body assembly faces the bearing surface. Following the conventional shape of the air-floating mower, the projected area of ​​the body assembly on the bearing surface is smaller when stored upright. Therefore, the storage area required on the bearing surface is smaller, allowing for more efficient use of the three-dimensional space above the bearing surface, thus reducing storage difficulty. Simultaneously, in the upright storage state, the projection of the air-floating mower's center of gravity on the bearing surface is located between the first and second support components; that is, the projection of the center of gravity does not exceed the projection range of the first and second support components used for support. This design provides good stability for the air-floating mower when stored upright, making it less prone to tipping over. Attached Figure Description

[0073] See Figures 1 to 3 An embodiment of the present invention provides an air-floating lawn mower for cutting lawns. The air-floating lawn mower includes a body assembly 100 and an operating assembly. The operating assembly includes a first operating member 200 and a second operating member 300. The body assembly 100 is provided with a motor, an impeller 130, a cutting member 140, and a first support portion 111. The body assembly 100 includes an open cavity in which the motor, impeller 130, and cutting member are housed. The cutting member is connected to the impeller 130, and the impeller 130 is connected to the motor. The motor drives the impeller 130 to rotate, thereby generating an airflow to suspend the air-floating lawn mower and drive the cutting member to rotate synchronously to cut the lawn. Along the forward direction of the air-floating lawn mower, the first support portion 111 is located at the rear end of the body assembly 100. The first operating member 200 is rotatably connected to the body assembly 100 about a first axis, and the second operating member 300 is rotatably connected to the first operating member 200 about a second axis parallel to the first axis. The first operating member 200 and / or the second operating member 300 include a second support portion 311. The air-floating mowing device has a retracted state, which includes, for example: Figure 3 The horizontal storage state shown and as Figure 2 The image shows the upright storage state. In the horizontal storage state, the extension direction of the second operating member 300 is basically parallel to the forward direction of the air-floating mower; in the upright storage state, the extension direction of the second operating member 300 is basically parallel to the direction from the front end to the rear end of the body assembly 100, and the second support part 311 is located at the outermost end of the operating assembly along the extension direction of the second operating member 300, so that the air-floating mower can be supported on the bearing surface by the first support part 111 and the second support part 311, and the projection point of the center of gravity of the air-floating mower on the bearing surface is located between the first support part 111 and the second support part 311, so that the air-floating mower is kept in the upright storage state.

[0074] In this application, in its upright storage state, the air-floating mower can be supported on a bearing surface by the first support part 111 and the second support part 311, achieving upright storage. When stored upright, the rear end of the body assembly 100 faces the bearing surface. Based on the conventional shape of the air-floating mower, compared to... Figure 1 The projected area of ​​the body component 100 on the bearing surface in the working state shown is as follows: Figure 3 The projected area of ​​the body component 100 on the supporting surface in the horizontally stowed state is shown. Figure 2When stored upright in the upright storage state, the projected area of ​​the body component 100 on the support surface is smaller. Therefore, the storage area required on the support surface is smaller, making fuller use of the three-dimensional space above the support surface and reducing storage difficulty. Simultaneously, in the upright storage state, the projection of the center of gravity of the air-floating mower on the support surface is located between the first support part 111 and the second support part 311. That is, the projection of the center of gravity of the air-floating mower does not exceed the projection range of the first support part 111 and the second support part 311 used for support, which gives the air-floating mower better stability when stored upright and makes it less prone to tipping over.

[0075] Specifically, the aforementioned bearing surface is the ground. The air-floating lawn mower also has features such as... Figure 1 The working status is shown. (See attached image.) Figure 1 and Figure 4 When the air-floating lawn mower is working, the motor outputs power to drive the cutting element 140 to rotate, thereby cutting the lawn. Specifically, the cutting element 140 is a blade, which can be in the shape of a straight line, a cross, or other shapes. The machine body assembly 100 includes a housing 110, which covers the motor, impeller 130, and cutting element 140, etc., and the motor is fixed to the housing 110. The cutting element 140 is located in a relatively lower position inside the housing 110, that is... Figure 1 In the operating state shown, the cutting element 140 is relatively short, making it easier to cut lawns with low profiles. This air-floating mowing device... Figure 1 In the operating state shown, the operator can hold the second operating component 300 to move the air-floating mower back and forth and left and right, changing the position of the cutting component 140 relative to the lawn, thereby cutting different areas of the lawn. For ease of understanding, the following will refer to... Figure 1 The orientation in the working state shown is explained.

[0076] See Figure 4 Specifically, the impeller 130 is connected to the output shaft of the motor to obtain power, and the cutting element 140 is fixedly connected to the bottom of the impeller 130. When the air-floating mower is working, the motor drives the impeller 130 to rotate, thereby driving the cutting element 140 to rotate to achieve cutting. At the same time, the rotation of the impeller 130 causes the airflow below the machine body assembly 100 to lift the entire air-floating mower upwards, suspending it at a certain height above the ground. This allows the air-floating mower to be moved forward, backward, left, and right by operating the second operating element 300. The suspension principle of the air-floating mower is existing technology and will not be described in detail here.

[0077] See Figures 1 to 3In some embodiments, in the upright storage state, the extension direction of the second operating member 300 is substantially parallel to the direction from the front end to the rear end of the body assembly 100. Alternatively, in some embodiments, in the upright storage state, the angle between the extension direction of the second operating member 300 and the bearing surface is close to 90 degrees; for example, an angle between 80 and 100 degrees is considered substantially parallel to the direction from the front end to the rear end. Specifically, the second operating member 300 is generally long and rod-shaped, and its extension direction is its own axial direction. When the above-mentioned condition of substantially parallelism is met, the air-floating mowing device can be kept relatively stable. Figure 2 As shown in the storage configuration, it is not easily tipped over.

[0078] In some embodiments, in the upright storage state, the second support 311 is flush with the first support 111, and the plane on which they lie is parallel to the bearing surface. As mentioned above, the bearing surface is the ground. When the second support 311 and the first support 111 meet the above conditions, they can be placed on a horizontal surface. Of course, in other embodiments, if the air-floating mowing device needs to be suitable for slopes, the second support 311 and the first support 111 can be designed to be non-flush, so that in the upright storage state, the plane on which they lie has an angle with the horizontal plane and matches the angle of the slope, thus enabling it to be placed more stably on the slope. The following embodiments will be described with the bearing surface being the horizontal plane.

[0079] See Figure 2 In some embodiments, in the upright storage state, the extension direction of the second operating member 300 is perpendicular to the bearing surface. Specifically, as mentioned above, when the terrain of the lawn is relatively flat and the bearing surface is approximately horizontal, the extension direction of the second operating member 300 in the upright storage state is vertical. At this time, the center of gravity of the second operating member 300 is located within its own projection range on the bearing surface, making it less prone to tipping over and exhibiting good stability. Of course, in some embodiments, the axial direction of the second operating member 300 in the upright storage state can also be inclined, for example, in... Figure 2 Based on this, the second operating element 300 can also be rotated counterclockwise by a certain angle.

[0080] See Figure 2 In some embodiments, in the upright, folded state, the second operating member 300 extends upwards beyond the body assembly 100. Specifically, Figure 2 From a viewing angle, when the bearing surface is approximately horizontal, the top of the second operating member 300 extends beyond the body assembly 100. Thus, in the upright, stowed state, the operator can easily hold the handle 330a and lift the entire air-floating mower.

[0081] See Figure 2In some embodiments, in the upright storage state, the first operating member 200 and the second operating member 300 are set at an acute angle. Of course, in other embodiments, they can also be approximately at a right angle, for example, in... Figure 2 From this perspective, the first operating component 200 is rotatably connected to the body assembly 100 near the rear end. At this time, the first operating component 200 and the second operating component 300 are approximately "L" shaped as a whole.

[0082] See Figure 1 In the working state, the angle between the first operating member 200 and the second operating member 300 is 180 degrees. This makes it easier for the operator to hold the second operating member 300 and move the machine body assembly 100 via the first operating member 200 to change the cutting area. Of course, in other embodiments, an obtuse angle may also be used. The first operating member 200 can rotate around a first axis, and the second operating member 300 can rotate around a second axis to switch between the working state and the storage state.

[0083] See Figures 1 to 3 In some embodiments, the first support portion 111 is located at the rear end of the housing 110, and the first support portion 111 protrudes rearward from the main body portion of the housing 110. Figure 1 In the shown operating state, the portion of the first operating member 200 used for connecting with the second operating member 300 is located at the rear of the body assembly 100. The second operating member 300 rotates forward relative to the first operating member 200 to achieve folding, thereby reaching... Figure 3 The state shown. In Figure 3 In the horizontally folded state shown, the entire air-floating mower can be rotated 90 degrees so that the rear end of the outer casing 110 faces the ground, thus reaching its position. Figure 2 The image shows the upright storage configuration.

[0084] Continue reading on air flotation lawn mowing devices Figures 1 to 3 In some embodiments, the second support portion 311 is disposed on the second operating member 300 and located at the rotatable connection between the second operating member 300 and the first operating member 200. Specifically, in Figure 1 In the operating state shown, the second operating member 300 rotates relative to the first operating member 200 to... Figure 3 In the horizontally folded state shown, the second support 311 is the rear end of the second operating member 300. Figure 3 In the indicated state, the entire air-floating mowing device is rotated 90 degrees clockwise, and the rear end of the outer shell 110 and the second support part 311 will face the bearing surface until they are supported on the bearing surface, thereby achieving an upright storage state.

[0085] In the above embodiments, in the upright storage state, only the second operating member 300 contacts the supporting surface, while the first operating member 200 does not. Further, in some embodiments, in the upright storage state, a portion of the upper part of the first operating member 200 also contacts the supporting surface. Specifically, one end of the first operating member 200 near the second operating member 300 includes a portion of the second support portion 311, and another portion of the second support portion 311 is disposed at the end of the second operating member 300 near the first operating member 200. Specifically, in... Figure 3 In the horizontally folded state shown, a portion of the second support portion 311 in the first operating member 200 extends rearward from the first operating member 200. For example, a portion of the second support portion 311 in the first operating member 200 may be located on the left and right sides of another portion of the second support portion 311 in the second operating member 300; or only on the left side; or only on the right side. Thus, in Figure 3 In the horizontal storage state shown, rotating the entire air-floating mower 90 degrees clockwise causes a portion of the second support portion 311 in the first operating member 200 and another portion of the second support portion 311 in the second operating member 300 to face the bearing surface until they are supported, thus achieving an upright storage state. In this embodiment, by simultaneously supporting the device with a portion of the second support portion 311 in the first operating member 200 and another portion of the second support portion 311 in the second operating member 300, the support area is larger, which can further improve the stability when storing it upright.

[0086] Of course, in other embodiments, the second support portion 311 may be provided only on the first operating member 200 and not on the second operating member 300. The arrangement of the second support portion 311 in the first operating member 200 is the same as in the previous embodiment.

[0087] Figure 8 This is a schematic diagram of the structure of the first operating component of the air-floating mowing device in one embodiment of this application.

[0088] See Figure 1 , Figure 3 and Figure 8 In some embodiments, the first operating member 200 includes a first rod 210 and a second rod 220. The first rod 210 is rotatably connected to one side of the body assembly 100, and the second rod 220 is rotatably connected to the other side of the body assembly 100. The rotatable connection position between the first operating member 200 and the second operating member 300 is located between the first rod 210 and the second rod 220, and the second support portion 311 is located between the first rod 210 and the second rod 220.

[0089] Specifically, in Figure 1 or Figure 3From the perspective shown, the bottom end of the first rod 210 is rotatably connected to the connector 112 on the right side of the body assembly 100, and the top end of the first rod 210 is rotatably connected to the right side of the second operating member 300. For example, a pin can be inserted through the top end of the first rod 210 and the right end of the second operating member 300 to achieve a rotatable connection between the two. Similarly, the bottom end of the second rod 220 is rotatably connected to the connector 112 on the left side of the body assembly 100, and the top end of the second rod 220 is rotatably connected to the left side of the second operating member 300. For example, a pin can be inserted through the top end of the second rod 220 and the left end of the second operating member 300 to achieve a rotatable connection between the two. The line connecting the two connectors 112 is the aforementioned first axis. Compared to the second operating element 300 being rotatably connected to only one part of the body assembly 100, in this embodiment, when the air-floating mower is working, the second operating element 300 can be operated to swing the air-floating mower left and right to change the cutting area, without having to lift the entire air-floating mower and move it left and right to change the cutting area, making it more convenient to use.

[0090] Continue reading Figure 1 , Figure 3 and Figure 8 In some embodiments, the first operating member 200 includes a third rod 230 located between the first rod 210 and the second rod 220. One end of the first rod 210 is rotatably connected to the body assembly 100 and the other end is connected to the third rod 230. One end of the second rod 220 is rotatably connected to the body assembly 100 and the other end is connected to the third rod 230. The second operating member 300 is rotatably connected to the third rod 230.

[0091] Specifically, the bottom end of the first rod 210 is rotatably connected to the connector 112 on the right side of the body assembly 100, and the top end is fixedly connected to the right end of the third rod 230. The bottom end of the second rod 220 is rotatably connected to the connector 112 on the left side of the body assembly 100, and the top end is fixedly connected to the left end of the third rod 230. That is, the entire first operating member 200 is U-shaped. The second operating member 300 is sleeved on the third rod 230, and the two are rotatably connected. Preferably, the first rod 210, the second rod 220, and the third rod 230 are integrally formed to give them higher strength. By setting the U-shaped first operating member 200, the connection between the first operating member 200 and the body assembly 100 can be made more stable and reliable.

[0092] Figure 19 A schematic diagram of the connector (left side for connection with the second rod) is shown in one embodiment of this application.

[0093] See Figure 1 and Figure 19In some embodiments, a limiting groove 116 is provided at the connection between the body assembly 100 and the first operating member 200 to limit the rotation of the first operating member 200. The limiting groove 116 includes at least two limiting walls, which are arranged along the forward direction of the air-floating grass mower to limit the rotation angle of the first operating member 200 relative to the body assembly 100. Specifically, the two limiting walls are provided on the connector 112. One of the two limiting walls is located on the front side to limit the forward rotation angle of the first operating member 200 relative to the body assembly 100, and the other is located on the rear side to limit the rearward rotation angle of the first operating member 200 relative to the body assembly 100. Through the cooperation of the two limiting walls, the first operating member 200 can only rotate within a certain range.

[0094] In some embodiments, at least one of the connections between the body assembly 100 and the first rod 210, and between the body assembly 100 and the second rod 220, is provided with a limiting groove 116. Specifically, at least one of the two connecting members 112 on the left and right sides of the body assembly 100 is provided with a limiting groove 116 to limit the rotation range of the first operating member 200. For example, the connecting member 112 on the right side is provided with a limiting groove 116, which limits the rotation range of the first rod 210 through its two limiting walls, thereby limiting the rotation range of the entire first operating member 200. Preferably, both connecting members 112 are provided with limiting grooves 116. The limiting groove on the connecting member 112 on the right side limits the rotation range of the first rod 210 through its two limiting walls, and the limiting groove on the connecting member 112 on the left side limits the rotation range of the second rod 220 through its two limiting walls, so as to achieve a better limiting effect.

[0095] Specifically, the two limiting walls include a first limiting wall 1161 disposed on one side of the limiting groove 116 and a second limiting wall 1162 opposite to the first limiting wall 1161. The first limiting wall 1161 is disposed at the front end of the limiting groove 116 to close the front end of the limiting groove 116, thereby limiting the angle of forward rotation of the first rod 210 and / or the second rod 220 relative to the body assembly 100. Specifically, the first limiting wall 1161 is curved, for example, it can be an arc surface. Of course, it can also be an inclined surface. When the first rod 210 and / or the second rod 220 rotates forward until it is blocked by the corresponding first limiting wall 1161, it reaches the forward limit position. The second limiting wall 1162 is located at a more rearward position, which can close the rear end of the limiting groove 116, or it can be left unclosed (the embodiment shown in the attached figure is the unclosed case). When the first rod 210 and / or the second rod 220 rotates forward until it is blocked by the corresponding second limiting wall 1162, it reaches the rear limit position.

[0096] Specifically, in some embodiments, one sidewall of the limiting groove 116 protrudes along the direction of the first axis to form a protrusion 1163, and a second limiting wall 1162 is part of the outer sidewall of the protrusion 1163. The distance between the protrusion 1163 and the other sidewall of the limiting groove 116 is greater than the diameter of the first rod 210 and / or the second rod 220. Specifically, the left sidewall of the limiting groove 116 protrudes to the right to form the protrusion 1163, and the second limiting wall 1162 is the front sidewall of the protrusion 1163. There is a gap between the right sidewall of the protrusion 1163 and the right sidewall of the limiting groove 116, which is greater than the diameter of the first rod 210 and / or the second rod 220.

[0097] Specifically, both the first rod 210 and the second rod 220 can move relative to the body assembly 100 along the first axis to be located between the corresponding first limiting wall 1161 and the second limiting wall 1162, or between the corresponding protrusion 1163 and the other side wall of the limiting groove 116. Generally, in the left-right direction, the first rod 210 and / or the second rod 220 are located between the corresponding first limiting wall 1161 and the second limiting wall 1162. When the first operating member 200 rotates forward, its rotation range is limited by the first limiting wall 1161, and when it rotates backward, its rotation range is limited by the second limiting wall 1162. However, in some cases, if the first operating member 200 is to be fully lowered, the required rearward rotation position will exceed the rear limit position. In this case, the first rod 210 and the second rod 220 can be operated so that the second rod 220 moves to the right to enter between the right side wall of the corresponding side protrusion 1163 and the right side wall of the limiting groove 116, and the first rod 210 moves to the left to enter between the left side wall of the corresponding side protrusion 1163 and the left side wall of the limiting groove 116. This allows the second limiting wall 1162 to no longer restrict the rearward rotation range of the first operating member 200, and the first operating member 200 can rotate to a larger angle.

[0098] Figure 9 This is a schematic diagram of the structure of the second operating component of the air-floating mowing device in one embodiment of this application. Figure 15 This is a schematic diagram of the structure of the second operating component of the air-floating mowing device in another embodiment of this application.

[0099] See Figure 1 , Figure 3 and Figure 9In some embodiments, the second operating member 300 includes a fourth rod 310, a fifth rod 320, and a handle 330a arranged sequentially along its own axial direction. These three components can be integrally formed, or any two adjacent components can be detachably connected. Preferably, the second operating member 300 is an integrally formed irregularly shaped aluminum tube, balancing high strength and light weight. The fourth rod 310 and the fifth rod 320 are generally round rods, but can also be square rods. The radial dimension of the end of the fourth rod 310 facing away from the fifth rod 320 is larger than the radial dimension of other areas of the fourth rod 310, making the fourth rod 310 approximately T-shaped overall. The end of the fourth rod 310 facing away from the fifth rod 320 is fitted onto the third rod 230, and the two are rotatably connected. The aforementioned second axis is the axis of the third rod 230. The aforementioned second support portion 311 protrudes outward from the end of the fourth rod 310 facing away from the fifth rod 320.

[0100] The operator can move the entire air-floating mower by holding the handle 330a, allowing it to cut different areas of the lawn. In some embodiments, the handle 330a is ring-shaped. Figure 15 In some other embodiments shown, the handle 330b is T-shaped. In other embodiments, the handle may also be triangular, elliptical, or other shapes.

[0101] Figure 5 This is a schematic diagram showing the projected positions of the first support portion and the second support portion of the air-floating mowing device in one embodiment of this application on the bearing surface.

[0102] See Figure 2 , Figure 3 and Figure 5 In some embodiments, the body assembly 100 includes two spaced-apart first support parts 111. In the upright storage state, the air-floating mower can be supported on the bearing surface by the second support part 311 and the two first support parts 111. The center point of the projection of the second support part 311 onto the bearing surface and the center point of the projection of the two first support parts 111 onto the bearing surface form a triangle, and the center of gravity of the air-floating mower is located inside the triangle at the projection point on the bearing surface.

[0103] It should be noted that neither the first support part 111 nor the second support part 311 is actually a point, but rather a region. Figure 5 In this configuration, the center position of the projection area of ​​the first support portion 111 and the second support portion 311 on the bearing surface is taken as their respective projection center point. Specifically, the two first support portions 111 protrude rearward from the main body of the outer shell 110, and are spaced apart in the left-right direction. Figure 3 From the perspective of the vertical storage shown, the projection point of the center of gravity of the air-floating mower on the bearing surface is... Figure 5 The center of gravity is projected as 410. The center points of the projections of the two first support parts 111 onto the bearing surface are at... Figure 5 The center points are shown as the first projection center point 420 and the second projection center point 430, respectively. The center point of the projection of the second support part 311 onto the bearing surface is shown as... Figure 5 The center point is shown as the third projection center point 440. The first projection center point 420, the second projection center point 430, and the third projection center point 440 form a triangle, and the centroid projection 410 is located within this triangle.

[0104] In the above embodiment, the provision of two spaced-apart first support portions 111 increases the number of support positions, thereby improving stability during upright storage and making the air-floating mowing device less prone to tipping over. Simultaneously, the three support portions are arranged in a triangular pattern, and the stability of the triangle further enhances stability during upright storage.

[0105] See Figure 3 and Figure 5 Preferably, in some embodiments, in the upright storage state, the projection point of the center of gravity of the air-floating mower on the bearing surface coincides with the center of gravity of the triangle. Specifically, the center of gravity of the triangle formed by the first projection center point 420, the second projection center point 430, and the third projection center point 440 coincides with the center of gravity projection 410. If placed in a coordinate system, the coordinates of the center of gravity projection 410 are the average of the coordinates of the three vertices of the triangle. The center of gravity projection 410 is located in a position relatively close to the center area of ​​the triangle, which can further improve the support stability.

[0106] See Figure 3 and Figure 5 Preferably, in some embodiments, the triangle is an equilateral triangle. Specifically, the triangle formed by the first projection center point 420, the second projection center point 430, and the third projection center point 440 is an equilateral triangle. At this time, the center of gravity projection 410 is located at the exact center of the triangle, and the three support parts for support are evenly distributed around the center of gravity projection 410, which can further improve the support stability.

[0107] See Figure 2 and Figure 3 In some embodiments, in the upright storage state, the second operating member 300 is locked to the body assembly 100. Specifically, the second operating member 300 is detachably connected to the body assembly 100; they are connected in the upright storage state and separated in the working state. Specifically, in the upright storage state, the second operating member 300 is locked to the outer shell 110, or locked to a component fixedly connected to the outer shell 110. In this embodiment, the second operating member 300 is locked to the body assembly 100, so in... Figure 2 In the indicated state, the second operating component 300 is less likely to rotate clockwise away from the body assembly 100 and re-deploy, thus maintaining a relatively stable position. Figure 2The state shown further improves the stability of upright storage and reduces the chance of tipping over.

[0108] Specifically, in some embodiments, the body assembly 100 includes a first latching portion, and the second operating member 300 includes a second latching portion; in the upright storage state, the first latching portion and the second latching portion latch together to achieve locking. Specifically, the first latching portion and the second latching portion can be configured such that one of them is a slot or hole and the other is a block; or, one of them is a slot or hole and the other is a hook; or, both of them are blocks.

[0109] In some embodiments, the first latching portion is located on the rear side of the body assembly 100. Specifically, the first latching portion is located at the rear end of the housing 110, or in the region near the rear side of a component within the housing 110. Positioning the first latching portion on the rear side makes it less visible from the front and sides, thus improving its aesthetics.

[0110] Figure 6 for Figure 4 A structural diagram of the mid-body components (left rear view); Figure 7 for Figure 6 Cross-sectional view of the main body components; Figure 9 This is a schematic diagram of the structure of the second operating component of the air-floating mowing device in one embodiment of this application; Figure 11 for Figure 9 A sectional view of a portion of the structure of the second operating component.

[0111] See Figure 6 and Figure 7 In some embodiments, the first latching portion is a latching slot 121 on the rear side of the body assembly 100; see also Figure 9 and Figure 11 The second locking part is a first locking block 3121 extending outward from the main body of the second operating member 300. In the upright storage state, the first locking block 3121 is locked into the locking slot 121.

[0112] See Figure 6 , Figure 7 and Figure 9 In some embodiments, the body assembly 100 includes a housing 110 and a motor housing 120 for mounting a motor. The housing 100 has a cavity, and the motor housing 120 is installed in the cavity. A slot 121 is provided on the rear side of the motor housing 120. The rear side of the housing 110 has a notch 114. In the upright storage state, a first locking block 3121 passing through the notch 114 is engaged with the slot 121. Of course, in other embodiments, the slot 121 can also be directly provided on the rear side of the housing 110.

[0113] See Figure 11Furthermore, the fourth rod 310 is also provided with a pusher 314 fixedly connected to the first locking block 3121. An elastic element, such as a spring, is connected between the pusher 314 and the fourth rod 310. The first locking block 3121 is formed by protruding radially outward from the outer peripheral surface of the fourth rod 310. Figure 3 In the process, when the second operating member 300 rotates toward the body assembly 100 until the fourth lever 310 is about to contact the top surface of the outer shell 110, the push knob 314 is pushed, causing the first locking block 3121 to move away from the locking slot 121 to avoid it, allowing the second operating member 300 to rotate into place. At this time, the elastic element is in a deformed state. When the push knob 314 is released, driven by the rebound force of the elastic element, the first locking block 3121 will move in the opposite direction to reset and enter the locking slot 121 through the notch 114, thereby locking the second operating member 300 to the body assembly 100.

[0114] See Figure 9 and Figure 11 Furthermore, in some embodiments, in addition to the first locking block 3121, the second operating member 300 also includes a second locking block 3122 extending outward from its own main body, with the first locking block 3121 and the second locking block 3122 arranged at intervals along the axial direction of the second operating member 300. See also... Figure 1 and Figure 6 The body assembly 100 is provided with a supporting surface 113. When the first locking block 3121 is engaged in the slot 121, the second locking block 3122 abuts against the supporting surface 113 to prevent the first locking block 3121 from disengaging from the slot 121. Specifically, the second locking block 3122 is also formed by radially protruding outward from the outer peripheral surface of the fourth rod 310. The supporting surface 113 is provided at the top of the outer casing 110. In this embodiment, the second locking block 3122 abuts against the supporting surface 113, which makes it difficult for the first locking block 3121 to disengage from the slot 121, thereby improving the stability of the second operating member 300 after locking with the body assembly 100, making it difficult for the two to separate. Especially when the first locking block 3121 is engaged in the slot 121, if the section between the first locking block 3121 and the second support part 311 of the second operating member 300 is held to lift the entire air-floating lawnmower. At this time, if the first support 311 is facing upwards and the handle 330a is facing downwards (equivalent to being in...), Figure 2 If the body assembly 100, located in slot 121, is rotated 180 degrees (from its original position), it will tend to move downwards due to its own gravity, thus causing the first locking block 3121 to disengage from slot 121. However, in this example, the second locking block 3122 abuts against the abutment surface 113, preventing the body assembly 100 located in slot 121 from moving downwards, thereby ensuring that the first locking block 3121 is stably fixed in slot 121 and will not disengage. Preferably, at least one component of the abutting force of the second locking block 3122 against the abutment surface 113 is opposite in direction to the direction of the slot 121 moving away from the first locking block 3121.

[0115] Figure 13 This is a schematic diagram of the air-floating mowing device in operation according to another embodiment of this application;

[0116] Figure 14 for Figure 13 Another structural schematic diagram of the air-flotation mowing device; Figure 17 for Figure 13 Enlarged view of the first snap-fit ​​portion in the embodiment shown; Figure 18 for Figure 14 An enlarged view of the second snap-fit ​​portion in the illustrated embodiment.

[0117] In other embodiments, in addition to the aforementioned snap-fit ​​structure, other conventional snap-fit ​​structures may also be used. For example, see [link to relevant documentation]. Figure 13 and Figure 17 In some embodiments, the first engaging portion includes a slot 115 and a recess 1151. The slot 115 is disposed on the top surface of the housing 110, and the sidewall of the slot 115 is recessed to one side to form the recess 1151. See also... Figure 14 and Figure 18 The second locking portion includes an insert block 313 and a third locking block 3131. The insert block 313 extends outward from the main body of the fourth rod 310 in one direction, and the third locking block 3131 protrudes outward from the interior of the insert block 313 in another direction. In the upright storage state, the insert block 313 is inserted into the slot 115, and the third locking block 3131 is engaged with the recess 1151.

[0118] Specifically, the outer peripheral surface of the fourth rod 310 also has a button 3132 protruding outward. The button 3132 is fixedly connected to the third locking block 3131, and the button 3132 and the fourth rod 310 are connected by an elastic element, such as a spring. Figure 3 When the second operating member 300 rotates toward the body assembly 100 until the insertion block 313 reaches the entrance of the slot 115, pressing the button 3132 causes the third locking block 3131 to retract inward toward the insertion block 313 to avoid it, allowing the insertion block 313 to be inserted into the slot 115. At this time, the elastic element is in a deformed state. Releasing the button 3132 causes the third locking block 3131 to move in the opposite direction and reset under the elastic force of the elastic element, locking into the recess 1151, thereby locking the second operating member 300 to the body assembly 100.

[0119] In addition to the aforementioned locking mechanism between the second operating element 300 and the body assembly 100 via a snap-fit ​​connection, in other embodiments, the second operating element 300 can also be locked to the body assembly 100 using threaded fasteners such as screws. Alternatively, in other embodiments, the second operating element 300 can be locked to the body assembly 100 via magnetic attraction. Other conventional detachable connection structures are also acceptable.

[0120] See Figure 1 In some embodiments, the relative positions of the second operating member 300 and the first operating member 200 are locked during operation. This ensures that the relative angle between the second operating member 300 and the first operating member 200 is fixed during operation, preventing relative rotation and facilitating more stable cutting.

[0121] Figure 10 for Figure 9 Exploded view of part of the structure of the second operating component; Figure 11 for Figure 9 A sectional view of a portion of the structure of the second operating component; Figure 12 for Figure 11 A magnified view of a portion of point A in the middle.

[0122] See Figures 10 to 12 Specifically, in some embodiments, the second operating member 300 includes a first clamping portion 315 and a second clamping portion 316. A portion of the first operating member 200 is located between the first clamping portion 315 and the second clamping portion 316. In the working state, the first clamping portion 315 and the second clamping portion 316 clamp a portion of the first operating member 200 to restrict the relative rotation between the second operating member 300 and the first operating member 200.

[0123] Specifically, as described above, the fourth rod 310 is sleeved outside the third rod 230. The fourth rod 310 includes a first clamping part 315 and a second clamping part 316, and the third rod 230 is located between the first clamping part 315 and the second clamping part 316. In the working state, the first clamping part 315 and the second clamping part 316 clamp the third rod 230 to restrict the relative rotation between the second operating member 300 and the first operating member 200. Specifically, in Figure 10 In this configuration, the first clamping portion 315 and the second clamping portion 316 are connected near the fifth rod 320 by threaded fasteners such as screws. The aforementioned second support portion 311 includes a first protrusion 3111 on the first clamping portion 315 away from the fifth rod 320, and a second protrusion 3112 on the second clamping portion 316 away from the fifth rod 320, with a gap 317 between the first protrusion 3111 and the second protrusion 3112. In the working state, the first clamping portion 315 and the second clamping portion 316 clamp the third rod 230, and the gap 317 decreases or even disappears. Outside the working state, the first clamping portion 315 and the second clamping portion 316 release the third rod 230, and the existence of the gap 317 allows the first clamping portion 315 and the second clamping portion 316 to rotate relative to the third rod 230.

[0124] See Figures 10 to 12Furthermore, in some embodiments, a connecting sleeve 318 is sleeved on a portion of the upper part of the first operating member 200. The connecting sleeve 318 is located between the first clamping part 315 and the second clamping part 316. A limiting part is protruding outward on the outer peripheral surface of the connecting sleeve 318, and a boss is protruding on the inner peripheral surface of the first clamping part 315 and / or the second clamping part 316. In the working state, the boss abuts against the limiting part. When the second operating member 300 is rotated to a position other than the working state, the boss separates from the limiting part.

[0125] Specifically, a connecting sleeve 318 is fitted onto the third rod 230. The outer circumferential surface of the connecting sleeve 318 has a first limiting portion 3181 and a second limiting portion 3182 protruding outwards. The connecting sleeve 318 can be a hollow eccentric wheel. The connecting sleeve 318 is fixedly connected to the outside of the third rod 230, or the two are integrally formed. The inner circumferential surface of the first clamping portion 315 has a first boss 3151 protruding, and the inner circumferential surface of the second clamping portion 316 has a second boss 3161 protruding. When the second operating member 300 rotates relative to the first operating member 200 to the angle of the working state, the knob 319 is rotated until the first boss 3151 abuts against the second limiting portion 3182, and the second boss 3161 abuts against the first limiting portion 3181, thereby restricting the rotation of the first clamping portion 315 and the second clamping portion 316 relative to the connecting sleeve 318, that is, restricting the rotation of the fourth rod 310 relative to the third rod 230. By setting two sets of corresponding limiting parts and bosses, a more stable locking effect can be achieved, thus enabling the air flotation mowing device to remain in a more stable working state.

[0126] Of course, in other embodiments, only one set of limiting parts may be provided, and correspondingly, only one set of bosses may be provided. Depending on the position of the limiting parts, the bosses may be provided on the first clamping part 315 or the second clamping part 316. Alternatively, bosses may be provided on both the first clamping part 315 and the second clamping part 316, thereby having two locking positions, so that the first operating member 200 and the second operating member 300 can have two locking positions at two different angles, thereby having two working states at two different angles.

[0127] Specifically, please continue to refer to Figure 10 The knob 319 is rotatably connected to the second clamping part 316. The knob 319 includes a cam part 3191. When the knob 319 is rotated to the point where the area with the largest radial dimension on the cam part 3191 abuts against the surface of the first clamping part 315, the first clamping part 315 can be pressed against the second clamping part 316, thereby causing the first boss 3151 to abut against the second limiting part 3182, and the second boss 3161 to abut against the first limiting part 3181. Specifically, the first clamping part 315 is provided with a through groove 3152, and the second clamping part 316 is provided with an extension block 3162 extending toward the first clamping part 315. The extension block 3162 extends through the through groove 3152 to the outside of the first clamping part 315 and is rotatably connected to the knob 319.

[0128] Furthermore, in some embodiments, the limiting portion is provided with a groove, and in the working state, the boss abuts against the groove wall. Specifically, the first limiting portion 3181 is provided with an inwardly recessed first groove 31811, and the second limiting portion 3182 is provided with an inwardly recessed second groove 31821. At the angle of the air-floating mower in the working state, when the first clamping portion 315 presses against the second clamping portion 316, the first boss 3151 abuts against the second groove 31821, and the second boss 3161 abuts against the first groove 31811. By providing grooves on the corresponding limiting portions to accommodate the corresponding bosses, a better limiting effect can be achieved on the corresponding bosses, allowing the air-floating mower to be maintained more stably in the working state.

[0129] Figure 15 This is a schematic diagram of the structure of the second operating component of the air-floating mowing device in another embodiment of this application;

[0130] Figure 16 for Figure 15 Exploded view of the end of the second operating component.

[0131] In addition to the locking method described in the aforementioned embodiments, the position locking of the first operating member 200 and the second operating member 300 in the working state can also be achieved through other methods. For example, see [link to documentation]. Figures 15 to 16 In some embodiments, a push part 340 is connected to the second operating member 300, and a positioning tooth 341 is provided on the push part 340. A positioning groove 3511 is provided on the first operating member 200. In the working state, the positioning tooth 341 is inserted into the positioning groove 3511 to restrict the relative rotation between the first operating member 200 and the second operating member 300.

[0132] Specifically, the first rotating shell 361 and the second rotating shell 362 are sleeved on the fourth rod 310 at the end away from the fifth rod 320, and the first rotating shell 361, the fourth rod 310, and the second rotating shell 362 are fixedly connected. A first fixed shell 351 is sleeved on the first rotating shell 361, and a second fixed shell 352 is sleeved on the second rotating shell 362. The first fixed shell 351 and the second fixed shell 352 are fixedly connected to the third rod 230 in the first operating member 200. The push part 340 is inserted into the first fixed shell 351 and can engage with the first rotating shell 361.

[0133] Specifically, the outer peripheral surface of the push part 340 is provided with a plurality of circumferentially spaced positioning teeth 341 and a plurality of circumferentially spaced hooks 342. The interior of the first fixed shell 351 is provided with a plurality of circumferentially spaced positioning grooves 3511. An elastic element, such as a spring, connects the push part 340 and the first fixed shell 351. When the push part 340 is not pressed, the hooks 342 are engaged with the first rotating shell 361, and the positioning teeth 341 are inserted into the positioning grooves 3511, thereby restricting the rotation of the first rotating shell 361 relative to the first fixed shell 351, that is, restricting the rotation of the second operating member 300 relative to the first operating member 200. When the push part 340 is pressed, the elastic element deforms, and at the same time, the hooks 342 are no longer engaged with the first rotating shell 361. At this time, the first rotating shell 361 can rotate relative to the first fixed shell 351, that is, the second operating member 300 can rotate relative to the first operating member 200. Once rotated to the desired position, the push part 340 is released, and under the drive of the elastic element's rebound force, the hook 342 is once again engaged with the first rotating shell 361, thereby achieving locking again.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
