Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.
[0024] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0025] like Figures 1 to 11 As shown in the figure, this utility model embodiment discloses a lawnmower, which includes a main body 100 and a grass collection box 200.
[0026] The main body 100 includes, but is not limited to, a mounting shell, a cutting mechanism, a walking mechanism, a circuit structure, and a control mechanism. The main body 100 and the grass collection box 200 are arranged along a first direction X, which can be understood as the direction of travel of the main body 100. Since the main body 100 needs to drive the grass collection box 200 to move, the grass collection box 200 is arranged in the direction of travel of the main body 100, thereby facilitating the collection of grass clippings cut by the main body 100.
[0027] The main body 100 has a recessed portion 101. The grass collection box 200 includes a box body 210 and a hook-on protrusion 220, which is located on the side of the box body 210 facing the main body 100. At least a portion of the hook-on protrusion 220 is located within the recessed portion 101, and the hook-on protrusion 220 and the recessed portion 101 are mutually restrained and engaged along a first direction X. When the main body 100 is connected to the grass collection box 200, the hook-on protrusion 220 on the grass collection box 200 is engaged into the recessed portion 101. At this time, the hook-on protrusion 220 can interfere with the inner wall of the recessed portion 101, thereby moving the hook-on protrusion 220 when the main body 100 moves.
[0028] Furthermore, one of the main body 100 and the casing 210 is provided with a plug-in protrusion 310, and the other is provided with a plug-in groove 320. The plug-in protrusion 310 and the plug-in groove 320 are plugged into each other along the first direction X. When at least a portion of the hook-on protrusion 220 is located within the recess 101, at least a portion of the plug-in protrusion 310 is located within the plug-in groove 320.
[0029] During the connection process, the grass collection box 200 is hooked onto the recess 101 of the main body 100 via the hooking protrusion 220, thus achieving the first step of engagement between the grass collection box 200 and the main body 100. Simultaneously, as the grass collection box 200 and the main body 100 approach each other, the insertion protrusion 310 automatically slides into the insertion slot 320 due to inertia.
[0030] In the embodiments disclosed in this application, the insertion protrusion 310 and the insertion groove 320 can assist in fixing the grass collection box 200 and the main body 100, thus avoiding the risk of large-scale shaking between the grass collection box 200 and the main body 100, thereby improving the connection reliability between the grass collection box 200 and the main body 100.
[0031] In the specific application, the hook-on protrusion 220 and the recess 101 form a hook-on structure, thus enabling the main body 100 to synchronously move the grass collection box 200. This can be understood as the hook-on protrusion 220 and the recess 101 limiting the grass collection box 200 in the front-back direction. Simultaneously, the insertion protrusion 310 engages with the left and right side walls of the insertion slot 320, thereby limiting the grass collection box 200 in the left-right direction. This avoids the risk of the main body 100 and the grass collection box 200 swaying left and right.
[0032] To further improve the connection stability between the hay collection box 200 and the main body 100, in another optional scheme, the number of insertion protrusions 310 can be at least two, namely a first insertion protrusion 3101 and a second insertion protrusion 3102. The first insertion protrusion 3101 and the second insertion protrusion 3102 can be arranged at intervals along a second direction Y, which is perpendicular to both the first direction X and the height direction of the main body 100. Here, the height direction of the main body 100 is as follows: Figure 3 The direction indicated by the Z-axis in the diagram. The number of insertion slots 320 can be at least two, namely a first insertion slot 321 and a second insertion slot 322. The first insertion protrusion 3101 is inserted into the first insertion slot 321, and the second insertion protrusion 3102 is inserted into the second insertion slot 322.
[0033] In this design, the first insertion protrusion 3101, the second insertion protrusion 3102, and the hanging protrusion 220 can achieve triangular fixation, thus further achieving stable fixation between the grass collection box 200 and the main body 100.
[0034] In the above scheme, the insertion port of the recessed portion 101 can face the top of the main body 100. When the grass collection box 200 is attached to the main body 100, the attachment protrusion 220 extends into the recessed portion 101 through the insertion port along the direction from the top to the bottom of the main body 100. When the main body 100 separates from the grass collection box 200, the grass collection box 200 is lifted along the direction from the bottom to the top of the main body 100, thereby causing the attachment protrusion 220 to detach from the recessed portion 101 through the insertion port, thus separating the main body 100 from the grass collection box 200. It should be noted that when the attachment protrusion 220 engages or disengages from the recessed portion 101, the insertion protrusion 310 and the insertion groove 320 also engage or disengage accordingly.
[0035] In the above scheme, when the grass collection box 200 and the main body 100 move radially, the hook protrusion 220 is likely to detach from the recess 101, which may lead to the risk of the grass collection box 200 separating from the main body 100.
[0036] In another optional embodiment, the hay collection box 200 may further include a movable latching member 230 and an operating member 240. The operating member 240 may be disposed on the box body 210, and the movable latching member 230 may be movably connected to the box body 210. The operating member 240 may be used to drive the movable latching member 230 to switch between a first position and a second position. When the movable latching member 230 is in the first position, the movable latching member 230 is engaged with the main body 100 along the height direction of the main body 100; when the movable latching member 230 is in the second position, the movable latching member 230 releases the constraint on the main body 100 along its height direction.
[0037] In this design, when the movable connector 230 is in the first position, it engages with the main body 100 along its height. At this time, after the hook protrusion 220 and the insertion protrusion 310 are connected, the movable connector 230 locks the main body 100 and the box body 210 together, thus preventing the hook protrusion 220 from detaching from the recess 101. This further ensures that the grass collection box 200 is securely mounted to the main body 100, thereby further improving the reliability of the connection between the grass collection box 200 and the main body 100.
[0038] Optionally, the operating component 240 may include a control button and a transmission mechanism. When the control button is pressed, the transmission mechanism drives the movable latching member 230 to move to a first position. When the user releases the pressure on the control button, the transmission mechanism drives the movable latching member 230 to move to a second position. The transmission mechanism can be a spring mechanism. When the control button is pressed, the control button overcomes the force of the spring mechanism, causing the movable latching member 230 to move to the first position; when the force on the control button is released, the spring mechanism drives the movable latching member 230 to switch to the second position. Alternatively, the transmission mechanism can also be a drive motor or a motor, and the control button can drive the drive motor or motor to switch the movable latching member 230 between the first and second positions. Of course, the transmission mechanism can also have other structures, which are not limited herein.
[0039] In another alternative embodiment, the main body 100 may include a housing 110 and a first handle 120. The housing 110 can provide a mounting base for other components of the main body 100. The first handle 120 may be located on the side of the housing 110 facing the grass collection box 200, and the first handle 120 and the housing 110 may form the aforementioned recess 101. The housing 110 is provided with a plug-in protrusion 310 or a plug-in groove 320.
[0040] The recess 101 has an opening, which is the aforementioned insertion port. At least a portion of the hook protrusion 220 extends into the recess 101 through the opening. The first handle 120 has a first edge and a second edge disposed opposite to each other. The first edge may be located on the side where the opening of the recess 101 is located. When the movable latching member 230 is in the first position, the movable latching member 230 may engage with the second edge in a limiting engagement along the height direction of the main body 100.
[0041] In this design, the active card connector 230 can be limited to the first handle 120, thus simplifying the structure of the lawnmower and making the lawnmower structure simpler.
[0042] In another embodiment, the insertion protrusion 310 may have a connecting end 310a and a free end 310b arranged opposite to each other. The connecting end 310a can be fixedly connected to the main body 100 or the box body 210. The free end 310b faces the insertion groove 320 and may have a snap-fit notch 310b1. The insertion groove 320 may have a snap-fit rod 3201. When the insertion protrusion 310 is inserted into the insertion groove 320, the snap-fit rod 3201 snaps into the snap-fit notch 310b1. In this solution, the free end 310b of the insertion protrusion 310 is snapped and fixed by the snap-fit rod 3201, thus further improving the fixing effect of the main body 100 and the grass collection box 200.
[0043] Furthermore, the snap-fit notch 310b1 can penetrate the protrusion 310 along the second direction Y. The axial direction of the snap-fit rod 3201 can be parallel to the second direction Y. The snap-fit notch 310b1 gradually narrows in the direction from the free end 310b to the connecting end 310a. In this design, the snap-fit notch 310b1 is a tapered structure, therefore it has better guiding properties, thereby improving the smoothness of the fit and thus improving the fit performance.
[0044] In another alternative embodiment, the insertion protrusion 310 may include a mounting base 311 and an extension protrusion 312. The end of the mounting base 311 opposite to the extension protrusion 312 may be a connecting end 310a, and the end of the extension protrusion 312 opposite to the mounting base 311 may be a free end 310b. The extension protrusion 312 may have a first side 3121 and a second side 3122 arranged opposite to each other along the height direction of the fuselage body 100. The distance between the first side 3121 and the second side 3122 gradually increases along the direction from the free end 310b to the connecting end 310a. In this embodiment, the free end 310b has a small area, thus facilitating insertion and avoiding the risk of interference, thereby further improving the reliability of the fit.
[0045] In another alternative embodiment, the housing body 210 may include a housing portion 211 and a handle portion 212. The handle portion 212 may include a second handle 2121 and a fixing base 2122. The fixing base 2122 may be disposed on the top of the housing portion 211. The second handle 2121 may be fixedly disposed on the top surface of the fixing base 2122. A hook-on protrusion 220 may be disposed on the bottom surface of the fixing base 2122. A plug-in protrusion 310 or a plug-in groove 320 is provided on the side wall of the housing portion 211 facing the main body 100.
[0046] In this design, the hook protrusion 220 can be set on the bottom surface of the fixing base 2122. Therefore, during connection, the hook protrusion 220 can be inserted into the recess 101 from top to bottom. Under the action of gravity, the housing part 211 can more easily slide the hook protrusion 220 into the recess 101, which is conducive to further improving the reliability of the fit.
[0047] In another alternative embodiment, the housing 211 may include a connecting frame 2111 and a storage housing 2112. A fixing seat 2122 may be disposed on the top of the connecting frame 2111. The connecting frame 2111 may be located between the storage housing 2112 and the main body 100. The connecting frame 2111 may be connected to the main body 100. The storage housing 2112 and the connecting frame 2111 are rotatably connected.
[0048] During specific operation, the connecting frame 2111 and the storage box 2112 can rotate. Therefore, under normal working conditions, the connecting frame 2111 can close the discharge port of the storage box 2112, thereby sealing the storage box 2112. Figure 1 As shown. When it is necessary to empty the grass clippings from the storage box 2112, the storage box 2112 can be rotated at a certain angle, thereby exposing the discharge port and allowing the grass clippings inside the storage box 2112 to be poured out, as shown. Figure 2 As shown.
[0049] This design facilitates the removal of grass clippings from the storage box 2112, thus improving the performance of the lawnmower.
[0050] In the above scheme, the grass collection box 200 also includes a collection mechanism 250, which can be mounted on the connecting frame 2111. The collection mechanism 250 can collect the grass clippings cut from the main body 100 into the storage box 2112. The collection mechanism 250 can be a negative pressure adsorption structure, for example, using components such as an air compressor or adsorption pump to adsorb the grass clippings. Alternatively, it can use a roller structure to roll up the grass clippings. The collection mechanism 250 can also have other structures, which are not limited herein.
[0051] In another alternative embodiment, both the hook-on protrusion 220 and the recess 101 can be strip-shaped structures. That is, the hook-on protrusion 220 can be a strip-shaped protrusion, and the recess 101 can be a strip-shaped groove or a strip-shaped hole. The extending direction of the strip-shaped structure can be perpendicular to both the first direction X and the height direction of the main body 100. In this design, the strip-shaped structure has a larger area, thus increasing the contact area and further improving the stability of the main body 100 and the grass collection box 200.
[0052] The above embodiments of this utility model mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.
[0053] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
