Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Please see Figures 1 to 3 As shown, the present invention discloses a lawnmower 100 for cleaning lawns. The lawnmower 100 includes an actuator assembly 3, a main body 200, and a detection device 300 connected to the main body 200. The detection device 300 includes a housing 1, which covers part of the main body 200 to form a receiving space 12 between the housing 1 and the main body 200. The housing 1 is provided with a mounting area 11, specifically located on the side of the housing 1 facing the receiving space 12. The actuator assembly 3 is received in the receiving space 12 and installed in the mounting area 11.

[0041] Preferably, the detection device 300 is covered on the top of the main body 200, and the receiving space 12 is recessed from the side of the detection device 300 close to the main body 200 toward the side away from the main body 200, so as to receive and protect the actuator assembly 3 and prevent the actuator assembly 3 from being damaged by external impact.

[0042] The exciter assembly 3 includes an audio exciter 32, a connector 31, and a fixing bracket 33. The connector 31 is located between the audio exciter 32 and the mounting area 11 to fix the audio exciter 32 to the lawnmower 100. Specifically, the audio exciter 32 is connected to the mounting area 11 through the connector 31, and the fixing bracket 33 covers the outside of the audio exciter 32 and can restrict the audio exciter 32 within the mounting area 11.

[0043] Specifically, the audio exciter 32 includes an oscillating body 321 and a base plate 323. The base plate 323 is connected to the housing 1 via a connector 31. The oscillating body 321 is used to drive the base plate 323 to vibrate, thereby driving the housing 1 to vibrate and emit sound outward.

[0044] In this embodiment, the size of the connector 31 is the same as the size of the base plate 323, so that the connector 31 can perfectly match the base plate 323, thereby improving the connection strength between the base plate 323 and the housing 1. Of course, in other embodiments, the size of the connector 31 can be larger or smaller than the size of the base plate 323, which is not limited here.

[0045] In this embodiment, the connector 31 is double-sided adhesive, preferably 3M double-sided adhesive. One side of the double-sided adhesive is bonded to the mounting area 11, and the other side is bonded to the base plate 323, so as to mount the audio exciter 32 on the mounting area 11. Of course, in other embodiments, the connector 31 can be a suction cup, the double-sided adhesive can be ordinary double-sided adhesive, and the connector 31 can also be a bonding adhesive or other polymer with adhesive effect, as long as the purpose of bonding the base plate 323 and the mounting area 11 can be achieved, there is no limitation here.

[0046] In this embodiment, both sides of the connector 31 are flat, and the side of the mounting area 11 and the base plate 323 near the mounting area 11 is also a clean and uniform flat surface to improve the connection strength between the base plate 323 and the mounting area 11. Of course, in other embodiments, the side of the mounting area 11 and the side of the base plate 323 near the mounting area 11 can be arc-shaped, wavy, or other shapes, or can be set as a rough surface, as long as the connector 31 can connect the base plate 323 and the mounting area 11, and can transmit the vibration effect of the base plate 323 to the mounting area 11 and drive the housing 1 to vibrate. There are no restrictions here.

[0047] In this embodiment, in order to improve the connection strength between the audio exciter 32 and the mounting area 11 and to prevent the audio exciter 32 from falling off the mounting area 11 during use, a fixing bracket 33 is provided on the outside of the audio exciter 32 to confine the audio exciter 32 within the mounting area 11. Of course, in other embodiments, the fixing bracket 33 may not be provided, and the audio exciter 32 and the mounting area 11 may be connected only by the connector 31. This is not a limitation.

[0048] Please see Figures 4 to 7As shown, the audio exciter 32 also includes a neck 324. The oscillating body 321 is fixedly connected to the base plate 323 via the neck 324. The fixing bracket 33 includes a receiving cavity 341 and an abutment plate 345. The oscillating body 321 is received in the receiving cavity 341, and the abutment plate 345 is received in the neck 324 and can abut against and be fixed to the base plate 323. Specifically, the base plate 323 and the oscillating body 321 are fixedly connected. The oscillating body 321 is cylindrical. The neck 324 is recessed inward from the connection between the oscillating body 321 and the base plate 323. That is, in the direction of the central axis of the oscillating body 321, the thickness of the neck 324 is greater than the thickness of the abutment plate 345. The abutment plate 345 extends toward the receiving cavity 341. That is, the abutment plate 345 covers part of the receiving cavity 341, so that when the oscillating body 321 is received in the receiving cavity 341, the abutment plate 345 is disposed opposite to the neck 324 and can move relative to the neck 324.

[0049] The mounting bracket 33 also includes a receiving portion 34, which is used to receive part of the audio exciter 32 and confine the audio exciter 32 within the mounting area 11. Specifically, the receiving portion 34 matches the audio exciter 32, a receiving cavity 341 is provided in the receiving portion 34, the oscillating body 321 is received within the receiving cavity 341, and an abutment plate 345 is provided on the side of the receiving portion 34 near the mounting area 11.

[0050] The fixed bracket 33 includes an opening 343 communicating with the receiving cavity 341, which allows the oscillating body 321 to pass through. Specifically, the receiving portion 34 has a "U" shape design, with the receiving cavity 341 located in the middle of the receiving portion 34. The opening 343 is located on one side of the receiving portion 34 and communicates with the receiving cavity 341. The size of the opening 343 matches the size of the oscillating body 321, allowing the oscillating body 321 to pass through the opening 343 and enter the receiving cavity 341. The end of the receiving cavity 341 away from the opening 343 is arc-shaped to match the cylindrical oscillating body 321. The oscillating body 321 is received within the receiving cavity 341, and a portion of the oscillating body 321 can abut against the side wall of the receiving cavity 341, thus supporting the oscillating body 321 from the receiving portion 341. Of course, in other embodiments, the oscillating body 321 can be square, elliptical, irregularly shaped, etc., and the end of the receiving cavity 341 away from the opening 343 can be correspondingly square, elliptical, irregularly shaped, etc., without limitation.

[0051] Please refer to details. Figure 6 and Figure 7As shown, the fixed bracket 33 also includes a receiving opening 344 formed by the abutment plate 345. The receiving opening 344 is for the neck 324 to pass through. The receiving opening 344 communicates with the opening 343 and is respectively provided on two adjacent sides of the fixed bracket 33. The neck 324 is received within the receiving opening 344. Specifically, the abutment plate 345 is a U-shaped plate structure to match the receiving portion 34. The receiving opening 344 communicates with the receiving cavity 341 and is set as a U-shape corresponding to the abutment plate 345. The opening direction of the receiving opening 344 is perpendicular to the opening direction of the opening 343, and the receiving opening 344 communicates with the opening 343, so that when the audio exciter 32 is assembled with the fixed bracket 33, the oscillating body 321 enters the receiving cavity 341 through the opening 343, and the neck 324 enters the receiving opening 344 from the opening 343. Preferably, the size of the receiving opening 344 matches the size of the neck 324.

[0052] The cavity 341 is provided with a receiving groove 342, and the oscillating body 321 is provided with a protrusion 322. The protrusion 322 is received in the receiving groove 342, and the thickness of the protrusion 322 is less than the thickness of the receiving groove 342 in the direction of the central axis of the oscillating body 321, so that the protrusion 322 can move in the receiving groove 342. Specifically, the receiving groove 342 is recessed inward from the side wall of the receiving cavity 341 and is located at one end of the receiving cavity 341 near the bottom plate 323. The protrusion 322 is located on the side of the oscillating body 321 near the bottom plate 323 and protrudes outward from the outer side wall of the oscillating body 321. Preferably, in the direction of the central axis of the oscillating body 321, the movement distance of the abutment plate 345 relative to the neck 324 is not greater than the movement distance of the protrusion 322 within the receiving groove 342, so that when the abutment plate 345 abuts against the bottom plate 323, the protrusion 322 can abut against or approach the side wall of the receiving groove 342. At the same time, the abutment plate 345 is confined between the bottom plate 323 and the protrusion 322 to limit the movement distance of the oscillating body 321 within the receiving cavity 341.

[0053] In this embodiment, the oscillating body 321 is provided with a protrusion 322 to restrict the abutment plate 345 between the base plate 323 and the protrusion 322, so as to prevent the fixing bracket 33 from separating from the audio exciter 32. Of course, in other embodiments, the oscillating body 321 may not be provided with a protrusion 322. Correspondingly, the receiving cavity 341 is not provided with a receiving groove 342. The abutment plate 345 and the side of the oscillating body 321 near the base plate 323 are only abutted to prevent the fixing bracket 33 from separating from the audio exciter 32. This is not a limitation.

[0054] Please refer to details. Figure 5 and combined Figure 7As shown, the abutment plate 345 has a limiting block 347 and a protrusion 346 on the side facing the base plate 323. When the abutment plate 345 abuts against the base plate 323, the limiting block 347 and the protrusion 346 abut against the side of the base plate 323 respectively, so as to realize the limiting connection between the audio exciter 32 and the fixed bracket 33. Specifically, the limiting block 347 and the protrusion 346 both extend from the abutment plate 345 towards the base plate 323. There are two limiting blocks 347, both located at the end of the abutment plate 345 facing the opening 343, and respectively located at both ends of the U-shaped abutment plate 345. There are two protrusions 346, both located on the side of the abutment plate 345 near the opening 343, and respectively located on both sides of the U-shaped abutment plate 345. Specifically, the protrusion 346 is located on the side of the abutment plate 345 away from the receiving opening 344.

[0055] Preferably, the limiting block 347 is inclined toward one side of the base plate 323 to guide the base plate 323 to move during the assembly of the fixing bracket 33 and the audio exciter 32. The extending direction of the protrusion 346 is perpendicular to the extending direction of the limiting block 347. The base plate 323 is square. When the abutting plate 345 abuts against the base plate 323, both limiting blocks 347 abut against the side of the base plate 323 near the opening 343, cooperating with the oscillating body 321 housed in the receiving cavity 341 to prevent... The fixed bracket 33 moves under the action of gravity, causing the oscillating body 321 to slide out of the receiving cavity 341; the distance between the two protrusions 346 matches the size of the base plate 323. When the abutting plate 345 abuts against the base plate 323, the two protrusions 346 abut against the opposite sides of the base plate 323 respectively, so as to restrict the base plate 323 between the two protrusions 346, prevent the fixed bracket 33 from moving relative to the base plate 323, and improve the accuracy of the abutment between the fixed bracket 33 and the base plate 323.

[0056] In this embodiment, the base plate 323 is square, and the protrusion 346 and the limiting block 347 abut against the two adjacent apex portions of the base plate 323. Of course, in other embodiments, the base plate 323 can be other shapes, such as circles, triangles, polygons, ellipses, etc. In this case, the positions of the protrusion 346 and the limiting block 347 on the abutment plate 345 can be changed accordingly, and there is no limitation here.

[0057] The receiving groove 342 is provided with a positioning groove 348, and the protrusion 322 is provided with a positioning block 325. When the oscillating body 321 is received in the receiving cavity 341, the positioning block 325 is limited and received in the positioning groove 348 to realize the positioning connection between the audio exciter 32 and the fixed bracket 33. Specifically, the positioning groove 348 is positioned opposite the opening 343 on the receiving groove 342, and the positioning groove 348 is formed by recessing inward from the side wall of the receiving groove 342. The size of the positioning block 325 matches the positioning groove 348, so that when the oscillating body 321 is received in the receiving cavity 341, the positioning block 325 is received in the positioning groove 348 to realize the positioning connection between the audio exciter 32 and the fixed bracket 33.

[0058] The audio exciter 32 also has a connection terminal (not shown) for connecting to other electronic devices to receive signals. This allows the oscillating body 321 to vibrate according to the signal, further causing the mounting surface to vibrate and emit sound. The connection terminal is electrically connected to the oscillating body 321 and is connected to other electronic devices via a cable. It should be noted that in this embodiment, the cable does not come into contact with other parts of the exciter assembly 3, nor with the mounting surface, to avoid the cable striking other components and generating noise when the oscillating body 321 vibrates. If the cable must come into contact with other components, a foam pad should be placed at the contact point to prevent noise.

[0059] Please refer to details. Figure 2 , Figure 3 and Figure 7 As shown, the fixing bracket 33 also includes a connecting portion 35, which is integrally formed with the receiving portion 34. The connecting portion 35 is located on the side of the receiving portion 34 away from the mounting area 11 and near the opening 343. The connecting portion 35 is used for fixed connection with the housing 1. Specifically, the housing 1 is provided with a fixing post 21, and the connecting portion 35 is connected to the fixing post 21 to connect the fixing bracket 33 and the housing 1. This prevents the fixing bracket 33 from falling off and also supports the audio exciter 32 through the fixing bracket 33, preventing the audio exciter 32 from falling off.

[0060] In one embodiment of the present invention, the fixing post 21 extends from the housing 1 toward the receiving space 12, and the connecting part 35 is provided with a movable groove 352. The fixing post 21 extends into the movable groove 352 and can move within the movable groove 352, so that the fixing bracket 33 can move relative to the housing 1. The movable groove 352 is provided on the side of the connecting part 35 near the opening 343. The movable groove 352 communicates with the receiving cavity 341 and is recessed from the receiving cavity 341 toward the direction away from the abutment plate 345. The movable groove 352 is waist-shaped, and the fixing post 21 is cylindrical and the diameter of the fixing post 21 is not greater than the shortest diameter of the movable groove 352, so that the fixing post 21 can extend into the movable groove 352 and move within the movable groove 352. Of course, in other embodiments, the cross-section of the fixing post 21 can be square or other shapes, as long as the purpose of the fixing post 21 extending into the movable groove 352 and moving within the movable groove 352 can be achieved, and there is no limitation here.

[0061] The connecting part 35 is also provided with a connecting hole 351 that communicates with the movable groove 352. Specifically, the connecting hole 351 is located on the bottom wall of the movable groove 352 on the side away from the receiving part 34 and penetrates through the bottom wall. The fixing post 21 moves within the movable groove 352 to correspond to the connecting hole 351. An external tool is used to pass through the connecting hole 351 and lock it with the fixing post 21 to connect the fixing bracket 33 to the fixing post 21, thereby further realizing the fixed connection between the fixing bracket 33 and the housing 1. Preferably, the external tool is a locking member 4.

[0062] In this embodiment, the connecting part 35 is located at one end of the receiving part 34 in the direction of the opening 343. Of course, in other embodiments, the connecting part 35 can also be located in other directions of the receiving part 34 according to the actual situation, or even in the middle of the connecting part 35. There is no limitation here.

[0063] In another embodiment of the present invention, the detection device 300 further includes a transition member 2, which is housed in the receiving space 12 and connected to the housing 1. Specifically, the housing 1 is provided with a locking post 13 extending toward the receiving space 12, and the transition member 2 is provided with a through hole 22 corresponding to the locking post 13. The locking member 4 passes through the through hole 22 to connect with the locking post 13, so as to fix the transition member 2 in the housing 1.

[0064] The fixing post 21 is located inside the housing 1, specifically on the transition member 2 and extending from the transition member 2 toward the receiving space 12, so that the fixing post 21 extends into the movable groove 352 and can move within the movable groove 352. In other words, the connecting part 35 can be sleeved on the outside of the fixing post 21 through the movable groove 352, so that the fixing bracket 33 can move relative to the fixing post 21. When the actuator assembly 3 is pasted in the mounting area 11, the connecting hole 351 corresponds to the fixing post 21, and the locking member 4 passes through the connecting hole 351 and connects to the fixing post 21 to lock the fixing bracket 33 onto the transition member 2. Preferably, the fixing post 21 and the locking post 13 are located on both sides of the transition member 2 and are staggered to avoid interference during locking. The locking member 4 is a screw.

[0065] By setting the fixing post 21, the locking part 4 is partially housed in the locking post 13 or the fixing post 21 during connection, preventing the locking part 4 from puncturing the housing 1 and achieving sealing and waterproofing of the housing 1.

[0066] In this embodiment, the detection device 300 also includes a detection component (not shown) housed in the housing space 12 for detecting nearby obstacles. The detection component and other structures of the lawnmower 100 can be configured according to existing technology, and will not be described in detail here.

[0067] In this embodiment, the mounting area 11 is located on the inner wall surface of the housing 1, and the inner wall surface is located in a vertical plane parallel to the forward direction of the lawnmower 100. That is, the actuator assembly 3 is mounted on the side wall of the housing 1. Of course, in other embodiments, the actuator assembly 3 can also be mounted in a vertical plane perpendicular to the forward direction of the lawnmower 100 or on the top wall of the housing 1. There is no limitation here.

[0068] The material of the housing 1 is a non-magnetic material. The material of the housing 1 can be one of the following: honeycomb sandwich panel, fine particle board (e.g., board made of HDF or MDF), plexiglass board, glass board, high-density foam board, dry wall panel, glass fiber, glass fiber reinforced plastic board, etc. Of course, in other embodiments, the housing 1 can be made of other materials that can provide good sound output, which is not limited here.

[0069] In this embodiment, the mounting area 11 is located on the side of the center of the side wall of the housing 1, and the audio exciter 32 is installed in the mounting area 11 to obtain a better sound output effect. Of course, in other embodiments, the mounting area 11 can also be located at the center of the side wall of the housing 1, or it can be located at the edge of the side wall of the housing 1. There are no restrictions here.

[0070] This invention discloses a method for installing an exciter assembly 3 on a lawnmower 100. For ease of description, the direction of the central axis of the oscillating body 321 is defined as the front-back direction x, the direction of the opening 343 of the fixed bracket 33 is defined as the up-down direction z, and the direction perpendicular to the front-back direction and the up-down direction is defined as the left-right direction y.

[0071] The installation method includes the following steps:

[0072] S1. Assemble and fix the connector 31, audio exciter 32 and fixed bracket 33 to form exciter assembly 3.

[0073] The connector 31 is made of 3M double-sided adhesive, which is attached to the side of the base plate 323 away from the vibrating body 321. Specifically, the side of the base plate 323 used for installation is first cleaned to ensure it is free of dust and dirt. Then, one side of the double-sided adhesive is attached to the base plate 323 to complete the connection between the audio exciter 32 and the connector 31.

[0074] In this embodiment, the base plate 323 is cleaned before connection to improve the bonding strength between the base plate 323 and the double-sided adhesive. Of course, in other embodiments, the cleaning step can be omitted, and there is no limitation here.

[0075] The oscillating body 321 of the audio exciter 32 is inserted into the receiving cavity 341 through the opening 343 of the fixing bracket 33 until the neck 324 is received in the receiving opening 344 and the abutment plate 345 is attached to the base plate 323. Then, the fixing bracket 33 is pushed to slide relative to the oscillating body 321, causing the abutment plate 345 to deform until the limiting block 347 and the protrusion 346 respectively abut against the side of the base plate 323.

[0076] In this embodiment, when the audio exciter 32 is assembled with the fixed bracket 33, the abutment plate 345 is in contact with the base plate 323. When the fixed bracket 33 or the audio exciter 32 is moved, the edge of the base plate 323 moves along the inclined surface of the limiting block 347, causing the abutment plate 345 to deform until the limiting block 347 slides past the base plate 323. Then, the abutment plate 345 returns to its original shape under the action of elastic force, and the limiting block 347 abuts against the edge of the base plate. Of course, in other embodiments, the audio exciter 32... When assembled with the fixed bracket 33, the abutment plate 345 may not be in contact with the base plate 323. That is, the abutment plate 345 moves between the protrusion 322 and the base plate 323. When the oscillating body 321 is housed in the receiving cavity 341, the fixed bracket 33 is moved so that the base plate 323 is in contact with the abutment plate 345 and the edge of the base plate 323 abuts against the limiting block 347 and the protrusion 346. As long as the purpose of housing the oscillating body 321 in the receiving cavity 341 can be achieved, there is no limitation here.

[0077] S2. Move the actuator assembly 3 into the lawnmower 100, so that the actuator assembly 3 and the mounting area 11 are at the same height and set relative to each other.

[0078] S3. Push the exciter assembly 3 toward the mounting area 11, and fix the audio exciter 32 in the mounting area 11 inside the lawnmower 100 via the connector 31.

[0079] Specifically, rotate the exciter assembly 3 so that the connector 31 is positioned between the mounting area 11 and the audio exciter 32 and aligned with the mounting area 11. Push the exciter assembly 3 toward the mounting area 11 until the side of the connector 31 away from the audio exciter 32 is attached to the mounting area 11.

[0080] It should be noted that, in the front-rear direction of the actuator assembly 3, the thickness of the limiting block 347 and the protrusion 346 is less than the combined thickness of the double-sided adhesive and the base plate 323, to prevent the limiting block 347 and the protrusion 346 from abutting against the mounting area 11, which would prevent the base plate 323 from being tightly fitted to the mounting area 11. Preferably, the thickness of the limiting block 347 and the protrusion 346 is not greater than the thickness of the base plate 323.

[0081] It should be noted that when the actuator assembly 3 is inserted into the lawnmower 100, the fixing post 21 is inserted into the movable groove 352. When the actuator assembly 3 moves toward the mounting area 11, the fixing post 21 also moves within the movable groove 352. When the actuator assembly 3 is attached to the mounting area 11, the fixing post 21 corresponds to the connecting hole 351 in the movable groove 352.

[0082] S4. Secure the fixed bracket 33 to the lawnmower 100.

[0083] Specifically, external tools (e.g., screws, bolts, etc.) are used to connect to the fixing post 21 through the connecting hole 351 to lock the connecting part 35 and the fixing post 21, causing the fixing bracket 33 to be pressed towards the mounting area 11, thereby increasing the connection strength between the audio exciter 32 and the housing 1, and further completing the installation of the exciter assembly 3. Of course, in other embodiments, after the connecting part 35 is connected to the fixing post 21, there may be no compressive force between the abutment plate 345 and the base plate 323. The fixing bracket 33 only serves to restrict the movement of the audio exciter 32, improve the connection stability between the audio exciter 32 and the mounting surface, and protect the audio exciter 32. This is not a limitation here.

[0084] In this embodiment, in step S1, the connector 31 is first pasted to the base plate 323, and then the audio exciter 32 is assembled to the fixing bracket 33. This arrangement can improve the connection accuracy between the connector 31 and the base plate 323. Of course, in other embodiments, the audio exciter 32 can be assembled to the fixing bracket 33 first, and then the connector 31 can be pasted to the base plate 323. Alternatively, the connector 31 can be directly pasted to the mounting area 11. There are no restrictions here.

[0085] In this embodiment, to facilitate the installation of the exciter assembly 3 inside the lawnmower 100, the fixing bracket 33 and the audio exciter 32 are assembled first, and then the whole assembly is moved into the lawnmower 100 for installation. This arrangement reduces the installation space inside the lawnmower 100. Of course, in other embodiments, the assembly can also be performed according to the following steps: first, double-sided tape is attached to the side of the mounting area 11 or the base plate 323 away from the oscillating body 321, and then the audio exciter 32 is attached to the mounting area 11 with double-sided tape to complete the assembly of the audio exciter 32 and the housing 1. Then, the fixing bracket 33 is moved so that the oscillating body 321 passes through the opening 343 and enters the housing. Inside cavity 341, in this step, the abutment plate 345 can move in contact with the base plate 323, or it can move between the base plate 323 and the protrusion 322, that is, the abutment plate 345 is not in contact with the base plate 323, so as to complete the initial assembly of the audio exciter 32 and the fixed bracket 33; then the fixed bracket 33 is moved in the front-back direction and the left-right direction, so that the base plate 323 is restricted between the limiting block 347 and the protrusion 346, so as to complete the assembly of the audio exciter 32 and the fixed bracket 33; finally, an external tool is used to connect to the fixed post 21 through the connecting hole 351 to fix the fixed bracket 33 to the housing 1, thus completing the assembly of the exciter assembly 3 and the lawnmower 100. There are no restrictions here.

[0086] In summary, the actuator assembly 3 of the present invention connects the base plate 323 and the mounting area 11 via the connector 31, avoiding the need for openings in the lawnmower 100 and improving the sealing performance of the lawnmower 100; by providing a fixing bracket 33 covering the outside of the audio actuator 32, the connection stability between the audio actuator 32 and the lawnmower 100 is improved, further extending the service life of the audio actuator 32; the abutment plate 345 abuts against the base plate 323, strengthening the connection strength between the base plate 323 and the mounting area 11; furthermore, by fixing... The bracket 33 covers the outside of the audio exciter 32 to prevent the audio exciter 32 from falling off during use and to extend the service life of the audio exciter 32. By setting the exciter assembly 3 inside the lawnmower 100, the lawnmower 100 can emit sound, which improves the practicality of the lawnmower 100. By setting the transition piece 2 connecting the housing 1 and the fixed bracket 33 inside the lawnmower 100, the opening on the housing 1 is avoided, which improves the sealing performance of the lawnmower 100 and also improves the waterproof and moisture-proof performance of the lawnmower 100.
