[0053] Wheeled power tools are tools that are driven by wheels and use an electric motor as the driving component to drive functional components to perform corresponding tasks. Examples include wheeled electric lawnmowers, snowplows, and road sweepers. Wheeled power tools mainly consist of a working component and a walking component. The working component includes functional components and a working motor that drives the functional components; the walking component includes walking wheels and a walking motor that drives the walking wheels. In some embodiments, the functional component can be a disc broom, driven by the working motor to sweep snow or dust; the functional component can also be a blade, driven by the working motor to cut grass or mow lawns.

[0054] Rear-walking lawnmowers are widely used in daily life as a type of wheeled power tool. To allow for the installation or attachment of user items and other accessories on rear-walking lawnmowers, and for easy storage of hay baskets, etc. Figures 1-15 As shown, this application provides a rear-walking lawn mower 500. The rear-walking lawn mower 500 includes a main unit 50, an operating device 52, a grass collection basket 55, and a mounting assembly 53.

[0055] The main unit 50 includes a walking assembly 503 and a cutting assembly 501. An operating device 52 is electrically connected to the main unit 50, allowing the user to operate the rear-walking lawnmower 500 from its rear. The operating device 52 includes a switch box 521, which houses at least electronic components for controlling the operating state of the cutting assembly 501. A grass collection basket 55 is selectively connected to the main unit 50 and is configured to collect grass clippings generated during cutting. The length of the grass collection basket 55 in the lateral direction of the rear-walking lawnmower 500 is equal to the width of the grass collection basket 55. A mounting assembly 53 includes at least one protrusion 531 disposed on the switch box 521 for mounting accessories. The span of the mounting assembly 53 in the lateral direction of the rear-walking lawnmower 500 is greater than or equal to 5 cm and less than the width of the grass collection basket 55.

[0056] In some embodiments, the span of the mounting component 53 in the lateral direction of the walk-behind lawnmower 500 can be 5cm, 7cm, 9cm, 11cm, 13cm, 15cm, etc. The mounting component 53 is designed according to the lateral length of the walk-behind lawnmower 500 and the width of the grass collection basket 55, so as to facilitate users to hang or install items and other accessories. No further restrictions are imposed here. When the mounting component 53 includes only one protrusion 531, the span of the mounting component 53 in the lateral direction of the walk-behind lawnmower 500 is the width of the protrusion 531.

[0057] By providing a protrusion 531 on the switch box 521, accessories can be installed. During use, the user simply needs to install items or accessories onto the protrusion 531, ensuring the ease of use of the walk-behind lawnmower 500. The span of the mounting component 53 in the lateral direction of the walk-behind lawnmower 500 is less than the width of the grass collection basket 55. When the walk-behind lawnmower 500 is in its stowed state, the mounting component 53 can be used to suspend the grass collection basket 55 on the walk-behind lawnmower 500, facilitating its storage. Since the protrusion 531 is located on the switch box 521, which is close to the user's operating side, it is convenient for the user to hang or install accessories on the protrusion 531, and easy to access.

[0058] In some embodiments, the protrusion 531 includes reinforcing ribs, and the load-bearing capacity of the protrusion 531 is greater than or equal to 1 kg. The load-bearing capacity of the protrusion 531 can be 2 kg, 3 kg, 4 kg, 5 kg, etc. The load-bearing capacity of the protrusion 531 can be designed according to the model and weight of the walk-behind lawnmower 500, without further limitations. By providing reinforcing ribs, the strength of the protrusion 531 can be improved, preventing deformation or even damage when the protrusion 531 is hung or installed with heavy attachments.

[0059] like Figure 5As shown, in some embodiments, the mounting component 53 includes two protrusions 531, and the distance L1 between the two protrusions 531 is greater than 5cm. The distance L1 between the two protrusions 531 can be 6cm, 7cm, 8cm, 9cm, 10cm, 11cm, etc., and is not limited in any particular way here. By providing two protrusions 531 on the switch box 521, the number of hanging mounting points can be increased, thereby allowing more items and accessories to be installed. The two protrusions 531 are spaced apart, forming a gap between them, which facilitates the placement of items on the two protrusions 531.

[0060] like Figure 5 As shown, in some embodiments, the mounting component 53 is symmetrical about the centerline of the switch box 521 and is located on the back of the switch box 521, with the back facing the user. This symmetrical arrangement of the mounting component 53 on the switch box 521 ensures aesthetic appeal. Furthermore, since the mounting component 53 is located on the user-facing side of the switch box 521, it facilitates the user's placement or retrieval of accessories.

[0061] like Figure 3 As shown, in some embodiments, the switch box 521 includes a housing 5211, with the protrusion 531 integrally formed with the housing 5211. By employing an integral molding process, the manufacturing of the protrusion 531 and the housing 5211 is facilitated, reducing subsequent assembly steps and ensuring the strength of the connection between the protrusion 531 and the housing 5211. The protrusion 531 and the housing 5211 can both be made of plastic and integrally formed using injection molding. In other embodiments, the protrusion 531 can also be mounted to the housing 5211 using screws 5021. This facilitates replacement when the protrusion 531 is damaged.

[0062] like Figure 5 As shown, in some embodiments, the switch box 521 is T-shaped, including a crossbeam 5212 and a protrusion 531 disposed on the crossbeam 5212. Since the crossbeam 5212 faces the user's body and is relatively long, the protrusion 531 is disposed on the crossbeam 5212 to facilitate the user in hanging or retrieving items.

[0063] like Figure 5 and Figure 7As shown, in some embodiments, the protrusion 531 protrudes relative to the housing 5211 of the switch box 521 to form a hanging mounting point. During operation of the walk-behind lawnmower 500, the user can easily hang or remove items from the protrusion 531, facilitating use. The protrusion 531 can be a hook for hanging bags, hats, and other items. A cup holder can be installed on the protrusion 531, allowing the user to carry water while working. A storage box can also be installed on the protrusion 531, allowing the user to place personal items such as mobile phones.

[0064] In some embodiments, the angle between the protrusion 531 and the plane containing the switch box 521 is greater than or equal to 0° and less than or equal to 90°. The angle between the protrusion 531 and the plane containing the switch box 521 can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, or 90°. The angle between the protrusion 531 and the switch box 521 can be flexibly arranged according to the application of the walk-behind lawnmower 500, and is not subject to excessive restrictions here. When the angle between the protrusion 531 and the plane containing the switch box 521 is an acute angle, a wedge-shaped space is formed. When an item is suspended on the protrusion 531, it can effectively prevent the item from falling due to vibrations generated by the operation of the walk-behind lawnmower 500.

[0065] like Figure 8 and Figure 9 As shown, in some embodiments, the grass collection basket 55 includes a frame 551 that can be hung on the mounting assembly 53. The frame 551 supports the grass collection basket 55. When the grass collection basket 55 is installed on the walk-behind mower 500, the opening of the grass collection basket 55 is kept in a stable open state to facilitate the collection of grass clippings. Moreover, when the walk-behind mower 500 is in the stowed state, the grass collection basket 55 can be hung on the mounting assembly 53 via the frame 551 for easy storage.

[0066] like Figure 8As shown, in some embodiments, the operating device 52 is disposed on the linkage assembly 51 of the walk-behind lawnmower 500. The linkage assembly 51 is foldable. When the walk-behind lawnmower 500 is in the stowed state, the switch box 521 is approximately perpendicular to the ground, and the grass collection basket 55 is suspended with its opening facing upwards. The linkage assembly 51 includes two first rods 511 connected to the main unit 50 and a second rod 512 connecting the two first rods 511. The operating device 52 is disposed on the second rod 512. When the walk-behind lawnmower 500 is working, the linkage assembly 51 is in the extended state, and the second rod 512 is located at the rear of the walk-behind lawnmower 500, making it convenient for the user to push the walk-behind lawnmower 500 while it is working. After the walk-behind lawnmower 500 is finished using, the linkage assembly 51 is folded to the stowed state, which can reduce the storage space occupied by the walk-behind lawnmower 500. When the walk-behind lawnmower 500 is in the stowed state, the opening of the suspended grass collection basket 55 faces upward, making it convenient to use the grass collection basket 55 to hold items.

[0067] like Figure 1 and Figure 2 As shown, in some embodiments, the switch box 521 includes an upper housing 52111 and a lower housing 52112 that cooperate with each other, and a mounting portion 531 is formed on the lower housing 52112 or the upper housing 52111. By designing the switch box 521 as a structure in which the upper housing 52111 and the lower housing 52112 are fastened together, it is convenient to arrange electronic components in the cavity formed by the fastening of the upper housing 52111 and the lower housing 52112. The upper housing 52111 and the lower housing 52112 can protect the electronic components and prevent dust and moisture from entering and affecting the electronic components.

[0068] like Figure 7 As shown, in some embodiments, the surface of the housing 5211 is provided with multiple protrusions 531, each protrusion 531 having a dimension of less than or equal to 10cm. The dimensions of each protrusion 531 can be 1cm, 1.5cm, 2cm, 2.5cm, 3cm, 3.5cm, etc., without further restrictions. By limiting the size of the protrusions 531, excessive size is avoided. Multiple protrusions 531 can be designed with the same size to ensure overall consistency, or different sizes can be designed according to the different items to be hung, thus flexibly meeting user needs.

[0069] In some embodiments, the mounting component 53 includes a recess that mates with a snap fastener. The recess creates a fixed point for engagement with the snap fastener. When hanging an object, the object is first connected to the snap fastener, and then the snap fastener engages with the recess. This method effectively allows for the hanging of the user's belongings and accessories.

[0070] In some embodiments, the accessory includes or is connected to a snap fastener. This arrangement facilitates the attachment's suspension on the housing 5211 via the snap fastener engaging with the recess.

[0071] In some embodiments, the accessory is a storage box with a load-bearing capacity of 10 kg or less. The storage box can have load-bearing capacities of 1 kg, 1.5 kg, 2 kg, 2.5 kg, 3 kg, 3.5 kg, etc. The storage box is fixed to the housing 5211 by utilizing the recessed portion and the snap-fit ​​mechanism. The storage box has a certain storage space, allowing users to place items such as water cups, mobile phones, and clothing.

[0072] To improve operator comfort and reduce fatigue when the walk-behind lawnmower is in operation, as follows: Figures 1-15 As shown, this application provides a rear-walking lawn mower. The rear-walking lawn mower 500 includes a main unit 50 and an operating device 52, the operating device 52 including a switch box 521, a first trigger 522 and a second trigger 523.

[0073] The main unit 50 includes a walking assembly 503 and a cutting assembly 501. An operating device 52 is electrically connected to the main unit 50 to allow the user to operate the rear-walking lawnmower 500 from the rear. A switch box 521 contains electronic components for controlling the operating states of the cutting assembly 501 and the walking assembly 503. A first trigger 522 is configured for user operation and rotates about a first pivot axis 526. A second trigger 523 is configured for user operation and rotates about a second pivot axis 527, which is substantially parallel to, or may coincide with, the first trigger 522 and the second trigger 523, respectively controlling one of the cutting assembly 501 and the walking assembly 503. Figure 5 and Figure 7 As shown, at least one of the first trigger 522 or the second trigger 523 is completely disposed on one side of the split surface 5213 of the switch box 521, and the lateral length L4 of the gripping parts of the first trigger 522 and the second trigger 523 in the rear-walking lawnmower 500 is greater than or equal to 5cm. The lateral length L4 of the gripping parts of the first trigger 522 and the second trigger 523 in the rear-walking lawnmower 500 can be 5.5cm, 6cm, 6.5cm, 7cm, 7.5cm, 8cm, etc. The gripping length L4 of the first trigger 522 and the second trigger 523 can be designed according to the model of the rear-walking lawnmower 500 and the target users, and no further restrictions are imposed here.

[0074] When the user operates the first trigger 522 and the second trigger 523, since the first trigger 522 and the second trigger 523 are relatively long, they can be pressed with fingers for easy operation, or held by hand to reduce operating fatigue and improve operating comfort during long-term operation.

[0075] like Figure 1 As shown, in some embodiments, the operating device 52 includes two second triggers 523, which are located on the left and right sides of the split surface 5213 of the switch box 521, respectively. By employing two identical second triggers 523, it is convenient for users to operate with either their left or right hand, thus accommodating users with different hand habits. Furthermore, the two second triggers 523 are not connected, saving materials compared to a single, integrated second trigger and avoiding interference with the switch box 521. In other embodiments, the two second triggers 523 can also integrate different functions, further enriching the control of the walk-behind lawnmower 500.

[0076] like Figure 7 As shown, in some embodiments, the lateral length L3 of the second trigger 523 in the rear-walking lawnmower 500 is less than or equal to 10 cm. The lateral length L3 of the second trigger 523 in the rear-walking lawnmower 500 can be 6 cm, 7 cm, 8 cm, 9 cm, or 10 cm. By limiting the length of the second trigger 523, it ensures ease of operation or gripping by the user's fingers while avoiding the inconvenience and waste of materials caused by an excessively long trigger 523.

[0077] like Figure 7 As shown, in some embodiments, the operating device 52 further includes a speed control knob 525, which is located between the two second triggers 523. By setting the speed control knob 525, the rotational speed of the cutting assembly 501 can be adjusted to adapt to different grass conditions and different users' walking speeds. The speed control knob 525 can be designed with multiple speed settings, and different rotational speeds of the cutting assembly 501 can be controlled by adjusting the angle interface of the speed control knob 525. This method ensures the flexibility of speed adjustment.

[0078] like Figure 5 As shown, in some embodiments, the first trigger 522 has a lateral length L2 of 30cm or more in the rear-walking lawnmower 500, and the first trigger 522 is symmetrical about the dividing plane 5213. The lateral length L2 of the first trigger 522 in the rear-walking lawnmower 500 can be 31cm, 32cm, 33cm, 34cm, 35cm, etc., without further limitation. By designing the first trigger 522 as an integral structure with a relatively long length, it is convenient for the user to simultaneously hold and operate the first trigger 522 with both hands while pushing the rear-walking lawnmower 500. In one embodiment, the first trigger 522 is used to control the operation of the cutting component 501; therefore, the user needs to continuously operate the first trigger 522 until the work is finished. Using the above-described method to operate the first trigger 522 with both hands can reduce operator fatigue. In some embodiments, the functions and structural designs of the first trigger 522 and the second trigger 523 can be reversed.

[0079] like Figure 5 As shown, in some embodiments, the switch box 521 is T-shaped and includes a crossbeam portion 5212, to which a first trigger 522 or a second trigger 523 is pivotally mounted. The relatively long crossbeam portion 5212 facilitates the arrangement of the first trigger 522 and the second trigger 523.

[0080] like Figure 1 As shown, in some embodiments, both the first trigger 522 and the second trigger 523 can be held simultaneously by a user with one hand when they are at their maximum rotation angle. When the user operates the first trigger 522 and the second trigger 523 at the same time, they only need to rotate the first trigger 522 and the second trigger 523 to their maximum angle, and then they can hold the first trigger 522 and the second trigger 523 simultaneously with one hand.

[0081] like Figure 4 As shown, in some embodiments, the walk-behind lawnmower 500 includes a linkage assembly 51, which includes two first rods 511 connected to the main unit 50 and a second rod 512 connecting the two first rods 511. By connecting the linkage assembly 51 to the main unit 50, the user can easily push the walk-behind lawnmower 500 to move and control the direction of movement via the linkage assembly 51.

[0082] like Figure 5 As shown, in some embodiments, the maximum rotation angle of both the first trigger 522 and the second trigger 523 is limited by the second lever 512. When the user operates the walk-behind lawnmower 500, they typically place their hand on the second lever 512 to push the lawnmower 500 forward. When it is necessary to operate the first trigger 522 and the second trigger 523 simultaneously, it is only necessary to rotate the first trigger 522 and the second trigger 523 until they are in contact with the second lever 512. This design facilitates user control of the walk-behind lawnmower 500.

[0083] like Figure 1 As shown, in some embodiments, the first trigger 522 and / or the second trigger 523 is a paddle. Designing the first trigger 522 and / or the second trigger 523 as a paddle enables a lightweight design of the first trigger 522 and / or the second trigger 523, and the paddle can effectively fit against the second lever 512, making it easy for the user to hold.

[0084] like Figures 1-9 As shown, this application also provides a rear-walking lawn mower 500, which includes a main unit 50, a linkage assembly 51, and an operating device 52.

[0085] The main unit 50 includes a walking assembly 503 and a cutting assembly 501. The linkage assembly 51 includes two first rods 511 connected to the main unit 50 and a second rod 512 connecting the two first rods 511. An operating device 52 is electrically connected to the main unit 50 to allow a user to operate the rear-walking lawnmower 500 from its rear. The operating device 52 includes a switch box 521, a first trigger 522, and a second trigger 523. The switch box 521 is mounted to the linkage assembly 51 and contains electronic components for controlling the operating states of the cutting assembly 501 and the walking assembly 503. The first trigger 522 is configured for user operation and rotates about a first pivot axis 526. The second trigger 523 is configured for user operation and rotates about a second pivot axis 527. The second pivot axis 527 is substantially parallel to, or may coincide with, the first pivot axis 526. The first trigger 522 and the second trigger 523 are configured to control one of the cutting assembly 501 and the traveling assembly 503, respectively. At least one of the first trigger 522 or the second trigger 523 is completely disposed on one side of the split surface 5213 of the switch box 521. The maximum rotation angle of both the first trigger 522 and the second trigger 523 is limited by the second rod 512.

[0086] When the user operates the walk-behind lawnmower 500, the user's hand rests on the second lever 512. At this time, the user can press the first trigger 522 and the second trigger 523 with their fingers to facilitate operation; or the user can rotate the first trigger 522 and the second trigger 523 to fit against the second lever 512 and hold it with their hand to reduce operating fatigue and improve operating comfort.

[0087] In some embodiments, the first trigger 522 and the second trigger 523 rotate in opposite directions. The first trigger 522 and the second trigger 523 are located on opposite sides of the second lever 512. When the first trigger 522 and the second trigger 523 are operated, the first trigger 522 and the second trigger 523 rotate towards each other and stop at the second lever 512, making it convenient for the user to grip.

[0088] In some embodiments, the maximum rotation angle of both the first trigger 522 and the second trigger 523 is less than or equal to 90°. The maximum rotation angle of the first trigger 522 and the second trigger 523 can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, or 90°, and no further restrictions are imposed here. Limiting the maximum rotation angle of the first trigger 522 and the second trigger 523 facilitates user operation.

[0089] like Figure 1 and Figure 5As shown, in some embodiments, the first trigger 522 and the second trigger 523 are respectively disposed on opposite sides of the plane of the switch box 521. With this arrangement, when the user operates the first trigger 522 and the second trigger 523, they do not interfere with each other, allowing the user to control the first trigger 522 and the second trigger 523 individually or simultaneously.

[0090] like Figure 5 As shown, in some embodiments, the curvature of at least one of the first trigger 522 and the second trigger 523 is similar to that of at least a portion of the second lever 512. Here, curvature refers to at least one of the first trigger 522 and the second trigger 523 being bent laterally, or at least one of the first trigger 522 and the second trigger 523 having an arcuate surface on the side facing the second lever. With this configuration, when the user operates a trigger with a curvature similar to that of the second lever 512, the trigger can fit snugly against the second lever 512, thus facilitating grip by the user.

[0091] In some embodiments, at least one of the first trigger 522 and the second trigger 523 is made of plastic. Using plastic reduces weight and achieves a lightweight design. Furthermore, plastic has good anti-aging properties, preventing weathering during long-term outdoor use.

[0092] like Figure 10 and Figure 12 As shown, in some embodiments, the first rod 511 of the linkage assembly 51 is rotatably connected to the main unit 50, and the linkage assembly 51 has a working position and a storage position relative to the main unit 50. When the linkage assembly 51 is in the working position, the second rod 512 is located behind the main unit 50, making it convenient for the user to push the walk-behind lawnmower 500 to work via the second rod 512. When the linkage assembly 51 is in the storage position, the second rod 512 is located at the head of the main unit 50, thereby allowing the linkage assembly 51 to fold and reduce the storage space it occupies.

[0093] like Figures 10-13 As shown, in some embodiments, a safety switch 54 is provided on the main unit 50, and a switch trigger 5111 is provided on the linkage assembly 51. When the linkage assembly 51 is in the working position, the safety switch 54 is not triggered, and the main unit 50 can work normally. When the linkage assembly 51 is in the folded storage position, the switch trigger 5111 triggers the safety switch 54, preventing the main unit 50 from starting. Through the above settings, it can be ensured that when the rear-walking lawnmower 500 is in the folded storage position, the main unit 50 cannot work, thereby ensuring safety.

[0094] like Figures 10-13 As shown, in some embodiments, the safety switch 54 is a contact sensor, a lever 541 is rotatably mounted on the main unit 50, and an elastic element 542 is provided between the lever 541 and the main unit 50. Figures 10-11As shown, when the linkage assembly 51 is in the folded storage position, the switch trigger 5111 presses the lever 541, and the lever 541 rotates to trigger the safety switch 54, thereby preventing the main unit 50 from starting. Figures 12-13 As shown, when the linkage assembly 51 switches from the storage position to the working position, the elastic element 542 pushes the lever 541 to reset, the safety switch 54 is deactivated, and the host 50 can work normally.

[0095] like Figure 6 As shown, in some embodiments, the switch trigger 5111 is mounted on the first rod 511. The switch trigger 5111 has a slot, through which the wiring harness 524 of the walk-behind lawnmower 500 is fixed to the first rod 511. By providing a slot on the switch trigger 5111 to act as a wire catch, it is convenient to fix the wiring harness 524.

[0096] like Figures 14-15 As shown, in some embodiments, the battery compartment assembly 502 of the rear-walking lawnmower 500 is independently installed and fixedly connected to the base plate of the rear-walking lawnmower 500 from top to bottom by multiple screws 5021. The battery compartment assembly 502 can be secured by tightening the screws 5021 from the front, eliminating the need to flip the main unit 50 over for fixing from the bottom of the base plate. This improves production efficiency, saves manufacturing costs, and reduces product costs; it also increases the ease of maintenance of the battery compartment assembly 502.

[0097] In some embodiments, the battery compartment assembly 502 is electrically connected to the switch box 521 via a wiring harness 524. By moving the switch box 521 from the host 50 to the linkage assembly 51, the space for two battery compartments or one storage compartment can be increased.

[0098] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
