[0029] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0030] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0031] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0032] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0033] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0034] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0035] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0036] Currently, the functional testing of lawn mowers after assembly is done manually. A lawn mower includes a mowing head with mowing rope wound inside. The mowing head needs to be struck to release the mowing rope before it can operate. Therefore, after manually striking the mowing rope to release it to a designated length, the lawn mower's speed and other parameters are tested. This process requires multiple people working together, which is time-consuming and labor-intensive. Furthermore, manual testing has a probability of incomplete or incorrect detection. Based on this, this application proposes an integrated lawn mower testing device that can automatically test lawn mowers, offering high testing efficiency and good testing results.

[0037] like Figure 1 and Figure 2 As shown, the integrated lawnmower testing device 100 includes a frame 101, a housing 102, and a testing platform 103. The frame 101 is in contact with the ground and supports the entire integrated lawnmower testing device 100. The housing 102 is mounted on the frame 101, and the testing platform 103 is mounted on the housing 102. The integrated lawnmower testing device 100 also includes a device switch 110, located outside the testing platform 103, used to control the start and stop of the integrated lawnmower testing device 100. The device switch 110 can be as follows: Figure 1 and Figure 2 The button shown can also be any other type capable of controlling the start and stop of the integrated lawnmower detection device 100; this application does not limit this. Specifically, after the operator places the lawnmower 200 on the detection platform 103 and manually presses the device switch 110, the integrated lawnmower detection device 100 starts detecting the lawnmower 200. To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The upper and lower sides are shown.

[0038] like Figure 3 and Figure 4a As shown, the lawn mower 200 includes a mowing head 210, a connecting rod 220, and a grip 230. The mowing head 210 houses and stores mowing rope 240, with a portion of the rope 240 retracted inside and a portion extending out to cut vegetation as the head rotates. One end of the connecting rod 220 connects to the mowing head 210, and the other end connects to the grip 230. The grip 230 has a connecting portion 231 for connecting to a power source, which can be a battery pack powering the lawn mower 200. The lawn mower 200 can be of various models, and the battery pack can have a nominal voltage of 18V, 24V, 36V, 48V, or 56V, etc. Figure 4a and Figure 4b As shown, the lawn mower 200 also includes a switch 250 and a switch control structure 251 connected to the switch 250. Both the switch 250 and the switch control structure 251 are mounted on the connecting rod 220.

[0039] The detection platform 103 includes a positioning component 300, a striking and releasing component 400, a cutting component 500, and a protective cover component 600. The positioning component 300 is used to fix the mower 200, which is detachably fixed to the positioning component 300. The striking and releasing component 400 is used to strike the mower head 210 of the mower 200, causing the mower head 210 to release the mower rope 240. The cutting component 500 is used to cut the released mower rope to a preset length. The protective cover component 600 is used to shield the mower head 210, and a fiber optic sensor 640 is installed on the protective cover component 600 to detect the direction and speed of the mower 200.

[0040] The detection platform 103 also includes a vision component 700 and an integrated display unit 710, with the vision component 700 and the integrated display unit 710 communicatively connected. The integrated lawnmower detection device 100 can detect multiple lawnmowers 200. To distinguish the detection results of different lawnmowers 200, such as... Figure 4a As shown, each mower 200 is equipped with a corresponding identification code 201, and the vision component 700 is used to identify the identification code 201.

[0041] like Figure 1 and Figure 3 As shown, the vision component 700 is positioned at the upper end of the integrated lawnmower detection device 100. The vision component 700 includes a camera 701 and a support frame 702, which stably fixes the camera 701 to the integrated lawnmower detection device 100. When the lawnmower 200 is placed into the integrated lawnmower detection device 100, the camera 701 first identifies the identification code 201 on the lawnmower 200, facilitating subsequent recording of the detection results. The identification code 201 identified by the camera 701 can be scanned by the MES (Manual Equipment System).

[0042] like Figure 1 and Figure 2 As shown, the integrated display unit 710 is located at the top of the integrated lawnmower detection device 100 and is fixed to the frame 101. After the camera 701 identifies the lawnmower 200, it transmits the identified information to the integrated display unit 710, where it is displayed. Simultaneously, all other components on the detection platform 103 are also communicatively connected to the integrated display unit 710, enabling the detection data to be displayed on it. Optionally, to ensure the security of the detection process, the integrated lawnmower detection device 100 can only be started after the integrated display unit 710 is activated; activating the integrated display unit 710 requires an account and password. Furthermore, the integrated display unit 710 can also display whether the connections of multiple components in the integrated lawnmower detection device 100 are normal.

[0043] The following is a detailed description of the multiple components included in the testing platform 103, and the process of the combined testing of the multiple components on the lawn mower 200.

[0044] like Figure 4a As shown, the positioning component 300 includes an upper positioning plane 301 and a lower positioning plane 302. The upper positioning plane 301 is used to clamp and fix the lawn mower 200, and the lower positioning plane 302 is in direct contact with the housing 102 and is detachably fixed to the housing 102. The upper positioning plane 301 and the lower positioning plane 302 are connected and fixed together by multiple connectors 303. Since the lawn mower 200 includes various models, and different models of lawn mower 200 have certain structural differences, in order for the integrated lawn mower detection device 100 to detect different models of lawn mower 200, the positioning component 300 also includes various models, and different models of positioning components 300 include structures that match the corresponding model of lawn mower 200.

[0045] like Figure 1 and Figure 4a As shown, the upper positioning plane 301 of the positioning component 300 includes multiple clamping members 310. Each clamping member 310 is a cavity that matches the shape and structure of the mower head 210, gripping part 230, and switch control structure 251 of the mower 200. The structure and placement of the clamping members 310 differ for different models of the positioning component 300 to adapt to different models of mowers 200. Therefore, the positioning component 300 is in direct contact with the housing 102, and is detachably fixed to the top of the housing 102, facilitating easy replacement with a positioning component 300 that matches the mower 200 to be tested. Meanwhile, as... Figure 2 and Figure 5 As shown, the chassis 102 also includes a clamping member 1021, which extends upward to the same height as the clamping member 310, and clamps the connecting rod 220.

[0046] In addition, such as Figure 6a and Figure 6b As shown, the positioning component 300 also includes a positioning pin 304 and multiple positioning limiters 305. The positioning pin 304 is disposed on the lower positioning plane 302 to connect the positioning component 300 to the housing 102. At least two of the multiple positioning limiters 305 are disposed on the lower positioning plane 302 to limit the position of the positioning component 300 as a whole. The positioning pin 304 and positioning limiters 305 are disposed in the same positions for different models of the positioning component 300, so that different models of the positioning component 300 can be installed into the integrated lawnmower detection device 100.

[0047] like Figure 4aAs shown, the positioning component 300 also includes multiple fixing members 320, which are respectively disposed on the positioning component 300 near the clamping member 310. The fixing members 320 are rotatable. When the device switch 110 is pressed to start the integrated lawnmower detection device 100, the fixing member 320 rotates to above the lawnmower 200 and presses against it, ensuring the lawnmower 200 is stably fixed. When the device switch 110 is pressed again to stop the operation of the integrated lawnmower detection device 100, or after the integrated lawnmower detection device 100 has completed its detection, the fixing member 320 rotates away from the lawnmower 200 again, and no longer presses against it, allowing the lawnmower 200 to be removed by the operator. The number of fixing members 320 can be as follows: Figure 4a The number of clamping members 310 shown is the same as the number of clamping members 310, or it may be greater than the number of clamping members 310. This application does not limit this number.

[0048] like Figure 4b As shown, the positioning component 300 also includes a pusher 330, which cooperates with the switch 250 of the mower 200. The pusher 330 pushes the switch 250 to start the mower 200, and the mowing head 210 starts to rotate. The process of the pusher 330 pushing the switch 250 is a test to see if the mower 200 can start normally.

[0049] Furthermore, before the mower 200 is placed into the integrated mower detection device 100, i.e., before the mower 200 is placed into the positioning assembly 300, it needs to be powered. A battery pack is inserted into the joint 231 of the mower 200. At this time, the battery pack is a simulated empty pack, which does not have any battery cell structure inside. The empty battery pack is connected to an external power source through wires to facilitate control of the power supply to the mower 200.

[0050] The detection platform 103 also includes a lifting device 601. One end of the lifting device 601 is fixed to the housing 102, and the other end is fixedly connected to the protective cover assembly 600, which can drive the protective cover assembly 600 to move up and down relative to the mower 200. When the mower 200 is placed in the integrated mower detection device 100, and the operator presses the device switch 110, the protective cover assembly 600 moves downward until it covers the mower head 210, which is the detection device. Figure 6a The state shown is as follows. When the device switch 110 is pressed again to stop the integrated lawnmower detection device 100, or after the integrated lawnmower detection device 100 completes its detection, the protective cover assembly 600 moves upwards away from the lawnmower head 210, which is the state shown. Figure 3The state shown is as follows. In this case, after the protective cover assembly 600 moves down to cover the mowing head 210, the pusher 330 mentioned above pushes the switch 250 to start the mowing machine 200, so that the mowing head 210 starts to rotate, ensuring the safety of the mowing machine 200 during the detection process.

[0051] The protective cover assembly 600 includes a first protective cover end face 610 and a second protective cover end face 620. The first protective cover end face 610 and the second protective cover end face 620 are located on opposite axial sides of the trimmer head 210, respectively, and the two protective cover end faces can cover the trimmer head 210. The two protective cover end faces are connected by a connecting end face 630, which is located at the upper end of the trimmer head 210. The three end faces form a semi-enclosed space that encloses the trimmer head 210. Figure 6a and Figure 6b As shown, the first protective cover end face 610 includes a first opening 611, and the connecting end face 630 includes a second opening 631. The first opening 611 cooperates with the striking wire release assembly 400, and the second opening 631 cooperates with the wire cutting assembly 500.

[0052] like Figure 7 As shown, the striking and releasing assembly 400 includes a striking block 410 and a fixing member 420. A cylinder is installed inside the striking block 410, allowing it to extend and retract in a certain direction. The fixing member 420 is fixed to a component fixedly connected to the chassis 102, allowing the striking and releasing assembly 400 to be fixed above the chassis 102. The fixed position of the striking and releasing assembly 400 corresponds to the position where the cover assembly 600 encloses the trimmer head 210. The striking block 410 strikes the trimmer head 210, causing it to release the trimmer rope 240. The size of the striking block 410 matches the size of the first opening 611. When the cover assembly 600 encloses the trimmer head 210, the striking block 410 passes through the first opening 611 to strike the trimmer head 210. Optionally, a shock absorber can be provided on the first opening 611. The striking block 410 strikes the shock absorber, indirectly striking the mowing head 210, so that the striking block 410 can strike the mowing head 210 with an appropriate force. The cylinder is a cylinder with an appropriate force set according to experimental parameters, enabling the striking block 410 to strike the mowing head 210 with an appropriate force for line release. The process of the line release assembly 400 striking the mowing head 210 serves as a test to determine whether the mowing machine 200 can release line normally.

[0053] like Figure 8As shown, the cutting assembly 500 includes a blade 510 and a locking part 520. A cylinder is also provided inside the cutting assembly 500, connected to the blade 510, allowing the blade 510 to extend and retract in a certain direction. The size of the blade 510 matches the size of the second opening 631, and the locking part 520 is located outside the blade 510. When the blade 510 passes through the second opening 631 and is inside the cover assembly 600, the locking part 520 engages with the outside of the second opening 631, and is fixed outside the second opening 631 so that the cutting assembly 500 is fixed to the cover assembly 600, thereby allowing the cutting assembly 500 to move up and down relative to the lawn mower 200 along with the cover assembly 600.

[0054] Different models of lawn mowers 200 have different suitable lengths for their trimming ropes 240. The suitable length refers to the length at which the trimming rope 240 achieves the best trimming effect and efficiency. After the striking block 410 strikes the trimming head 210 to release the trimming line, the blade 510 needs to cut the trimming rope 240 to the desired length according to the model of the lawn mower 200. This ensures that the remaining trimming rope 240 is the preset length (i.e., the suitable length), facilitating subsequent testing of the lawn mower 200's steering and speed. Therefore, the cylinder, with a suitable cylinder diameter set according to experimental parameters, allows the blade 510 to be in multiple cutting positions, cutting any trimming rope 240 to the required suitable length.

[0055] like Figure 5 As shown, the chassis 102 has a third opening 1022, which is aligned vertically with the position of the trimming rope 240, allowing the trimming rope 240 cut by the blade 510 to fall through the third opening 1022. Figure 1 and Figure 9 As shown, the integrated grass trimmer detection device 100 also includes a feed box assembly 120, which is disposed below the detection platform 103, inside the housing 102, and aligned vertically with the opening 1022. The feed box assembly 120 includes an opening 121, allowing cut grass trimming rope 240 falling from the opening 1022 into the feed box assembly 120, which collects the cut grass trimming rope 240. The feed box assembly 120 also includes a handle 122, which allows the feed box assembly 120 to be removed from the housing 102 to empty the collected grass trimming rope 240. The shape of the feed box assembly 120 is not limited in this application.

[0056] After the mowing head 210 releases the mowing rope 240 by striking the mowing assembly 400, and the mowing rope 240 is cut to a suitable length by the mowing assembly 500, it is necessary to test the direction and speed of the mowing machine 200. The testing components are still located in the protective cover assembly 600.

[0057] like Figure 6a and Figure 6b As shown, the protective cover assembly 600 includes multiple fiber optic sensors 640, which are respectively disposed on the first protective cover end face 610 and the second protective cover end face 620, distributed along the circumference of the trimmer head 210, i.e., the rotation direction of the trimmer head 210. Thus, the multiple fiber optic sensors 640 can detect the direction of rotation based on the circumferential passing sequence of the trimmer rope 240, and detect the rotational speed based on the circumferential passing frequency of the trimmer rope 240. Specifically, the fiber optic sensors 640 are through-beam fiber optic sensors, and will be referred to as through-beam fiber optic sensors 640 in the following description. This application uses three groups of through-beam fiber optic sensors 640 as an example for specific description. However, the number of through-beam fiber optic sensors 640 can also be greater than three, and this application does not limit this.

[0058] The through-beam fiber optic sensor 640 includes a fiber optic sensor transmitter 641 and a fiber optic sensor receiver 642. A transmitter array, consisting of three fiber optic sensor transmitters 641, is disposed on the first protective cover end face 610, positioned above the first opening 611 and arranged at equal intervals circumferentially. A receiver array, consisting of three fiber optic sensor receivers 642, is disposed on the second protective cover end face 620, positioned above the trimmer head 640 and arranged at equal intervals circumferentially. Each fiber optic sensor transmitter 641 is coaxially aligned with its corresponding fiber optic sensor receiver 642, thus forming three sets of independent parallel optical path channels.

[0059] As the trimmer rope 640 rotates, its trajectory sequentially blocks the optical path channels. Three sets of parallel optical path channels are arranged in sequence, allowing the order in which the trimmer rope 640 passes through these channels to determine its rotation sequence, and thus whether it is rotating clockwise or counterclockwise. Therefore, the through-beam fiber optic sensor 640 can detect whether the rotation sequence of the trimmer 200 is normal.

[0060] Meanwhile, when the trimmer rope 640 rotates and blocks the optical path channel, there is a blocking time. Based on the time interval between the blocking of adjacent optical paths and the installation angular distance between them, the angular velocity of the trimmer rope 640 can be calculated. Then, converting the angular velocity into a rotational speed value gives the rotational speed of the trimmer rope 640. Therefore, the through-beam fiber optic sensor 640 can detect the rotational speed of the trimmer 200 and whether the speed is within an appropriate range.

[0061] After the through-beam fiber optic sensor 640 detects the direction and speed of the mower 200, the integrated mower detection device 100 completes the detection of the mower 200. At this time, the fixing member 320 rotates away from the mower 200, and the mower 200 is no longer pressed against by the fixing member 320. The operator can then remove the mower 200 from the integrated mower detection device 100. The detection result of the mower 200 is displayed on the integrated display unit 710 and stored.

[0062] The above describes the automatic detection of the lawn mower 200 by multiple components in the integrated lawn mower detection device 100. These components can also be manually controlled to detect the lawn mower 200. Optionally, the lawn mower 200 can be manually controlled by operating multiple components through the integrated display unit 710. The manual control detection process will not be detailed here, as it is the same as the automatic detection process corresponding to each component.

[0063] The integrated lawnmower testing device 100 proposed in this application can test lawnmowers 200 of different models. It can directly test the lawnmower 200's on / off function, line release function, steering, and speed. The entire process requires no manual operation except for placing and handling the lawnmower 200, making the testing process quick and effective. Furthermore, the testing data can be stored for easy retrieval at any time.

[0064] 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.
