Description

Vehicle front structure and garden robot Technical Field

[0001] This application relates to the field of intelligent device technology, specifically to a vehicle front structure and a yard robot. Background Technology

[0002] In related technologies, garden robots can help users complete daily maintenance tasks in their gardens, offering various functions such as lawn mowing, snow removal, and leaf blowing. The garden robot's functional execution mechanism is located on the front of the vehicle. To allow the front of the robot to rotate freely, the inventor designed a rotating shaft as the axis for the functional execution mechanism. However, when only the functional execution mechanism needs maintenance, the inventor discovered that the shaft must be removed from the mounting bracket before the functional execution mechanism can be separated from the rear mounting bracket. After maintenance, the shaft must be reassembled back onto the mounting bracket before the functional execution mechanism can be reassembled, requiring extra work and requiring improvement. Furthermore, the inventor found that because the rotation of the front requires significant space, a large clearance needs to be reserved between the front and the body to prevent interference caused by the rotation. However, this clearance results in an excessively large gap between the front and the body, affecting the overall size of the garden robot and requiring further improvement.

[0003] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Technical issues

[0004] In view of this, this application provides a front structure and a yard robot to solve the problem in the related art that it is inconvenient for maintenance personnel to maintain the yard function actuator, and that additional parts need to be disassembled, which is time-consuming and labor-intensive. Technical solutions

[0005] To achieve one or more of the above objectives or other objectives, this application proposes a vehicle front structure, including a courtyard function actuator, a mounting bracket, a first rotating shaft, and a connecting seat;

[0006] The first rotating shaft is rotatably connected to the mounting bracket;

[0007] The connecting seat is disposed on the first rotating shaft, and the connecting seat and the first rotating shaft rotate synchronously;

[0008] A first fastener is provided between the courtyard function actuator and the connecting seat for detachable connection;

[0009] The mounting bracket has an inspection through hole, which is aligned with the first fastener. External force can be applied through the inspection through hole to disassemble or assemble the first fastener.

[0010] This application proposes a vehicle front structure, including a courtyard function actuator, a connecting seat, a mounting bracket, a first rotating shaft, and a vehicle front body;

[0011] The first rotating shaft is rotatably connected to the mounting bracket, the vehicle head body is connected to the first rotating shaft, and the vehicle head body and the first rotating shaft rotate synchronously; a first fastener is provided between the courtyard function actuator and the connecting seat for detachable connection, and the connecting seat is provided on the first rotating shaft;

[0012] The first rotating shaft is provided with a first oscillating element, which rotates with the first rotating shaft;

[0013] The mounting bracket is provided with a limiting structure, and a first baffle and a second baffle are formed on the limiting structure at intervals. The first swing member is located between the first baffle and the second baffle, and the first baffle and the second baffle cooperate to limit the rotation range of the first swing member.

[0014] This application also proposes a garden robot, including any of the above-described front structure and a body, wherein the front structure and the body are detachably connected. Beneficial effects

[0015] Implementing the embodiments of this application will have the following beneficial effects:

[0016] This application provides a detachable connection between the courtyard function actuator and the connecting seat using a first fastener. An inspection hole exposes the first fastener to the outside, allowing maintenance personnel to manually or with tools remove it through the hole, thus separating the courtyard function actuator from the connecting seat. Maintenance personnel can directly detach the courtyard function actuator without additionally removing the first rotating shaft from the mounting bracket, simplifying the disassembly and assembly process. This application features a simple structure, low improvement cost, and facilitates disassembly and installation by maintenance personnel, avoiding unnecessary operational procedures.

[0017] This solves the problem in related technologies where maintenance personnel face difficulties when inspecting the front courtyard function actuator, as it requires additional disassembly of other parts, which is time-consuming and labor-intensive.

[0018] This application limits the rotation range of the first swinging component by using a limiting structure, thereby limiting the rotation range of the front body. Since the undulation of the ground on which the garden robot travels is usually limited, and the front body does not need to swing significantly, limiting the rotation range of the front body satisfies the need for the front body to adapt to undulating ground while preventing the front body from rotating too much relative to the body. Consequently, while ensuring that the front body and the body do not interfere with each other, the required clearance space between them is reduced, the gap between the front body and the body is narrowed, and the overall size of the garden robot is prevented from becoming too large.

[0019] This solves the problem in related technologies where the rotation of the robot's front end results in a large gap between the robot's front end and body, affecting the overall size of the robot.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] This application provides a front-end structure that facilitates quick disassembly by maintenance personnel, improving disassembly and assembly efficiency and simplifying operating procedures.

[0040] Please refer to Figures 1 to 3. One embodiment of this application describes a vehicle front structure, including a courtyard function actuator 1, a mounting frame 2, a first rotating shaft 3, and a connecting seat 4.

[0041] The courtyard function actuator 1 is used to perform courtyard maintenance functions. It can be, but is not limited to, actuators with functions such as mowing, snow sweeping, and leaf blowing, and can be set according to actual needs.

[0042] The first rotating shaft 3 is rotatably connected to the mounting bracket 2. The connecting seat 4 is disposed on the first rotating shaft 3, and the connecting seat 4 and the first rotating shaft 3 rotate synchronously.

[0043] In this way, the courtyard function execution mechanism 1 can be rotated. The courtyard function execution mechanism 1 can rotate around the first rotating shaft 3, which makes it easy for the courtyard function execution mechanism 1 to adapt to different terrains and optimize the courtyard function execution effect.

[0044] A first fastener 5 is provided between the courtyard function actuator 1 and the connecting seat 4 for detachable connection. The mounting bracket 2 is provided with an inspection through hole 211, which is aligned with the first fastener 5. External force can be applied through the inspection through hole 211 to disassemble or assemble the first fastener 5.

[0045] Before adopting the solution of this embodiment, when maintenance personnel need to repair the courtyard function actuator 1, they need to remove the first rotating shaft 3 and other components from the mounting frame 2 before they can separate the courtyard function actuator 1. After the repair is completed, the first rotating shaft 3 and other components must be reinstalled on the mounting frame 2. However, maintenance personnel do not need to repair the first rotating shaft 3 and other components. Therefore, in this embodiment, a first fastener 5 is provided between the courtyard function actuator 1 and the connecting seat 4 for detachable connection. The first fastener 5 is exposed to the outside by opening an inspection through hole 211, which allows maintenance personnel to manually or with tools remove the first fastener 5 through the inspection through hole 211, thereby separating the courtyard function actuator 1 from the connecting seat 4. Maintenance personnel can directly remove the courtyard function actuator 1 without having to remove the first rotating shaft 3 from the mounting bracket 2. When resetting after maintenance, external force can be applied to the first fastener 5 through the inspection through hole 211 to lock the courtyard function actuator 1 and the connecting seat 4, which simplifies the disassembly and assembly process. This embodiment has a simple structure, low improvement cost, and is convenient for maintenance personnel to disassemble and install, avoiding unnecessary operation procedures.

[0046] Optionally, the mounting bracket 2 can be used to connect to an external structure, such as the vehicle body 10.

[0047] Optionally, the first fastener 5 can be, but is not limited to, screws, locating pins, clips, or other fasteners. Optionally, the number of the first fasteners 5 can be set according to the actual connection stability requirements.

[0048] Optionally, the first rotating shaft 3 and the connecting seat 4 can be a fixed connection or a detachable connection. For example, the first rotating shaft 3 and the connecting seat 4 are welded together.

[0049] In some alternative embodiments, as shown in Figure 1, the first fastener 5 is a screw with its head facing the access hole 211. The screw locks the yard function actuator 1 onto the connecting seat 4. When disassembly is required, maintenance personnel can use tools from the outside to remove the yard function actuator 1 and the mounting bracket 2 by passing through the access hole 211 and screwing in the screw.

[0050] In some alternative embodiments, referring to Figures 3 to 5, the mounting frame 2 includes a rear end wall 21 and two side end walls 22 connected to the left and right sides of the rear end wall 21. An inspection through hole 211 is provided on the rear end wall 21. The two ends of the first rotating shaft 3 are rotatably connected to the two side end walls 22 respectively. The first rotating shaft 3 can rotate relative to the mounting frame 2, and the connecting seat 4 rotates synchronously with the first rotating shaft 3, thereby allowing the courtyard function actuator 1 to pitch and swing. When the vehicle front structure moves on uneven ground, the courtyard function actuator 1 can swing up and down under external force to adapt to different terrains, improving the adaptability of the vehicle front structure.

[0051] In some optional embodiments, as shown in FIG4, bushings 6 are provided on both side end walls 22, and the two ends of the first rotating shaft 3 are respectively rotatably inserted into the two bushings 6. The bushings 6 can provide support, making the rotation of the courtyard function actuator 1 more stable and reliable, protecting the first rotating shaft 3 from unnecessary external damage, ensuring the correct position of the first rotating shaft 3, and allowing the courtyard function actuator 1 to obtain more stable rotation performance.

[0052] In some alternative embodiments, as shown in FIG4, both ends of the first rotating shaft 3 are recessed with retaining grooves, and retaining springs 7 are held in the two retaining grooves. The retaining springs 7 are used to press against the bushing 6 to axially limit the first rotating shaft 3. The bushing 6 is provided with a second fastener 8, which locks the bushing 6 to the side end wall 22.

[0053] Furthermore, the diameters at both ends of the first rotating shaft 3 are reduced and inserted into the two bushings 6 respectively.

[0054] In some alternative embodiments, as shown in FIG4, in order to facilitate the installation of the first rotating shaft 3 and the bushing 6, the side end wall 22 is provided with an assembly hole 221, which extends forward to communicate with the outside.

[0055] In some alternative embodiments, as shown in Figures 2 and 4, a cover 9 is removably provided over the access hole 211. The cover 9 is used to prevent foreign objects from entering the front structure from the outside.

[0056] In some alternative embodiments, as shown in FIG5, the end of the courtyard function actuator 1 facing the connecting seat 4 has a second rotating shaft 12, which extends in the front-rear direction. A bearing 13 is provided between the second rotating shaft 12 and the connecting seat 4 for rotatable connection, and a first fastener 5 secures the bearing 13 and the connecting seat 4. This enables the courtyard function actuator 1 to achieve a second degree of rotational freedom, allowing it to swing left and right about the second rotating shaft 12, while the first degree of rotational freedom is to pitch about the first rotating shaft 3. When the vehicle front structure moves on uneven ground, the courtyard function actuator 1 can swing left and right and up and down under external force to adapt to different terrains, further improving the adaptability of the vehicle front structure.

[0057] Bearing 13 is used to reduce rotational friction, making rotation smoother. In some alternative embodiments, as shown in FIG5, the outer ring of bearing 13 is detachably connected to connecting seat 4, that is, the first fastener 5 locks the outer ring of bearing 13 onto connecting seat 4. The inner ring of bearing 13 is inserted into the second rotating shaft 12, and the outer ring and inner ring of bearing 13 rotate relative to each other.

[0058] In some alternative embodiments, as shown in Figures 1 and 5, the yard function actuator 1 includes a bracket 11, with one end of a second rotating shaft 12 away from the bearing 13 connected to the bracket 11, and the second rotating shaft 12 rotating synchronously with the bracket 11. The bracket 11 can be used to mount various functional modules, such as a lawnmower module 14, etc.

[0059] In some alternative embodiments, as shown in FIG3, a mowing module 14 is provided on the bracket 11. The mowing module 14 includes a first lifting mechanism 141 and a blade unit 142. The first lifting mechanism 141 is provided on the bracket 11 and is connected to and controls the lifting of the blade unit 142.

[0060] The cutter head unit 142 is used to rotate and cut grass, realizing the grass-cutting function of the front structure. The first lifting mechanism 141 is used to control the height of the cutter head unit 142, thereby meeting the user's need for cutting grass at different heights.

[0061] In some optional embodiments, as shown in FIG3, the first lifting mechanism 141 includes a first driving device 1411, a guide structure 1412, and a lifting frame 1413. The first driving device 1411 is connected to and controls the lifting frame 1413 to lift and lower. The cutter head unit 142 is connected to the lifting frame 1413, thereby realizing the lifting and lowering control of the cutter head unit 142. The guide structure 1412 is erected on the bracket 11, and the lifting frame 1413 is slidably connected to the guide structure 1412. Under the drive of the first driving device 1411, the lifting frame 1413 slides up and down along the guide structure 1412.

[0062] Optionally, the first drive device 1411 may include a first motor and a threaded component. The first motor connects to and controls the rotation of the threaded component. A nut is fitted onto the threaded component, and the threaded component and the nut are threadedly connected. The nut is fixedly connected to the lifting frame 1413. When the first motor drives the threaded component to rotate, the nut and the lifting frame 1413 move up and down along the threaded component as a whole. Since the rotation of the first motor is continuous, the position of the nut and the lifting frame 1413 as a whole in the guide structure 1412 can be continuously and steplessly adjusted, thereby realizing the stepless height adjustment function of the lawn mowing module 14.

[0063] The guide structure 1412 can be columnar, and its number can be adjusted according to actual needs. To improve lifting stability, multiple guide structures 1412 can be distributed circumferentially around the outer periphery of the threaded part, resulting in greater balance and stability. During lawn mowing, when the lawn is uneven, the cutter head unit 142 may accidentally cut into soil piles or other debris. Multiple guide structures 1412 can distribute the impact force received by the cutter head unit 142, improving stability and preventing damage to the lawn mowing module 14.

[0064] In some alternative embodiments, the blade unit 142 may include a second drive device and a blade head. The second drive device is connected to the lifting frame 1413, and the output end of the second drive device is connected to the blade head. The second drive device controls the rotation of the blade head, thereby realizing the rotating grass-cutting function of the blade head.

[0065] In some alternative embodiments, as shown in FIG3, a movable wheel module 15 is provided on the support 11. The movable wheel module 15 includes a second lifting mechanism 151 and a movable wheel 152, which is used to roll on the ground. The second lifting mechanism 151 is provided on the support 11 and is connected to and controls the lifting of the movable wheel 152, thereby realizing the height adjustment function of the movable wheel 152.

[0066] Optionally, the bracket 11 is frame-shaped, with its rear end connected to the second rotating shaft 12. The bracket 11 is equipped with a first lifting mechanism 141 and two sets of cutter head units 142. The first lifting mechanism 141 connects to and controls the lifting and lowering movements of the two sets of cutter head units 142. The bracket 11 is equipped with two sets of moving wheel modules 15, which are located in front of the two sets of cutter head units 142.

[0067] Optionally, an elastic element may be provided on the mounting bracket 2. The elastic element is connected to the bracket 11 and provides a pulling force from the bracket 11 to the mounting bracket 2 to reduce the interaction force between the vehicle front structure and the ground.

[0068] In some optional embodiments, as shown in FIG6, the front structure includes a front body 01 and a hook-lock module 02. The front body 01 contains the aforementioned courtyard function actuator 1, and the hook-lock module 02 contains the aforementioned mounting bracket 2. As shown in FIG5, the hook-lock module 02 is provided with a hook-lock mechanism 021, which is used to lock external equipment to achieve connection with external equipment, such as the vehicle body 10. On the one hand, the hook-lock module 02 facilitates the detachable connection between the front structure and external equipment. On the other hand, the courtyard function actuator 1 and the connecting seat 4 are detachably connected by a first fastener 5, and the first fastener 5 is exposed to the outside by opening an inspection through hole 211, which facilitates the separation of the hook-lock module 02 from the front body 01 and improves the modularity of the hook-lock module 02. As an example, the vehicle body 10 is provided with a pin, which can be inserted into the hook-lock module 02. The hook-lock mechanism 021 locks the pin, thereby realizing the connection function between the hook-lock module 02 and the vehicle body 10.

[0069] This application also provides a front structure that can be applied to equipment such as garden robots, to avoid the situation where the overall size of the garden robot becomes too large due to the large rotation range of the front body 01.

[0070] One embodiment of this application provides a vehicle front structure, which, as shown in Figures 9 and 13, includes a mounting bracket 2, a first rotating shaft 3, and a vehicle front body 01.

[0071] [Corrected according to detailed rule 91 28.09.2025] The first rotating shaft 3 is rotatably connected to the mounting bracket 2, and the front body 01 is connected to the first rotating shaft 3. The front body 01 and the first rotating shaft 3 rotate synchronously. The courtyard function actuator 1 is detachably connected to the connecting seat 4 by a first fastener 5, and the connecting seat 4 is set on the first rotating shaft 3.

[0072] A first oscillating element 04 is provided on the first rotating shaft 3, and the first oscillating element 04 rotates with the first rotating shaft 3.

[0073] The mounting bracket 2 is provided with a limiting structure 03, as shown in Figure 8. The limiting structure 03 has a first baffle 0311 and a second baffle 0312 that are spaced apart.

[0074] The first swing member 04 is located between the first baffle 0311 and the second baffle 0312. The first baffle 0311 and the second baffle 0312 cooperate to limit the rotation range of the first swing member 04.

[0075] When this embodiment is applied to devices such as garden robots, when the vehicle head body 01 has a large swinging motion tendency under the action of external force, the first swing member 04 abuts against the first baffle 0311 or the second baffle 0312, thereby restricting the rotation of the first swing member 04, so that the vehicle head body 01 is always within the permitted rotation angle range.

[0076] The included angle between the first baffle 0311 and the second baffle 0312 can be adjusted according to actual needs, thereby controlling the first oscillating component 04 to rotate within the required angle range.

[0077] Optionally, to accommodate most ground undulations while ensuring a small clearance space 09, the angle between the first barrier 0311 and the second barrier 0312 is between 20 and 40 degrees; preferably, the angle between the first barrier 0311 and the second barrier 0312 is 30 degrees. In some optional embodiments, with the initial position of the first swing member 04 as zero degrees, the first swing member 04 can swing forward 15 degrees and backward 15 degrees.

[0078] In this embodiment, the rotation amplitude of the first swinging member 04 is limited by the limiting structure 03, thereby limiting the rotation amplitude of the front body 01. Since the undulation of the ground on which the garden robot travels, such as a lawn, is usually limited, the front body 01 does not need to swing a large amplitude to adapt. Therefore, by limiting the rotation amplitude of the front body 01, the requirement for the front body 01 to adapt to undulating ground can be met, while avoiding large rotation of the front body 01 relative to the body 10. Furthermore, while ensuring that the front body 01 and the body 10 do not interfere with each other, the clearance space 09 required between them can be reduced. Referring to Figure 14, the gap between the front body 01 and the body 10 is reduced, avoiding the situation where the overall size of the garden robot is too large.

[0079] On the other hand, when the rotation angle between the front body 01 and the body 10 tends to exceed the range, the limiting structure 03 can be used to provide structural support and limit the rotation amplitude of the first swing member 04, thus providing protection. For example, when the garden robot collides with an external object, the front body 01 and the body 10 bend, and the limiting structure 03 is subjected to force, preventing excessive bending between the front body 01 and the body 10, thus providing protection; or, for example, when the garden robot is lifted, the front body 01 and the body 10 rotate relative to each other, limiting the rotation amplitude of the first swing member 04, preventing excessive bending between the front body 01 and the body 10, thus providing protection.

[0080] Optionally, different types of courtyard function execution modules can be installed on the main body 01 of the vehicle head, which can be used for, but are not limited to, performing functions such as mowing, snow removal, and leaf blowing.

[0081] In some alternative embodiments, as shown in Figures 8 to 12, the limiting structure 03 is recessed with a first limiting groove 031, and a first baffle 0311 and a second baffle 0312 are formed on the groove wall of the first limiting groove 031. The first swinging member 04 is located in and swings within the first limiting groove 031.

[0082] As shown in Figure 10, the first limiting groove 031 can be similar to a fan-shaped groove, and the first baffle 0311 and the second baffle 0312 are located on the front and rear sides of the first limiting groove 031, respectively.

[0083] In some alternative embodiments, the limiting structure 03 may consist of two blocks, which are mounted on the mounting bracket 2. The first swing members 04 of the two blocks are spaced apart and located between the two blocks. The two blocks abut against the first swing members 04, thereby limiting the rotation range of the first swing members 04. The limiting structure 03 may also be configured in other forms, as long as it limits the rotation range of the first swing members 04; these details will not be elaborated here.

[0084] In some alternative embodiments, the mounting bracket 2 includes a rear end wall 21 and two side end walls 22 respectively connected to the left and right ends of the rear end wall 21. The two ends of the first rotating shaft 3 are rotatably connected to the two side end walls 22 respectively. The first rotating shaft 3 and the front body 01 of the vehicle move in a synchronized pitching motion.

[0085] [Correction 28.09.2025 based on Rule 91] In some alternative embodiments, as shown in Figures 11 and 13, a third limiting groove 222 is provided on the side end wall 22, and a protrusion 032 is formed on the limiting structure 03. The protrusion 032 is located within the third limiting groove 222, and the third limiting groove 222 restricts the displacement of the protrusion 032 in the front-back direction. The third limiting groove 222 is used to restrict the rotation of the protrusion 032 in the front-back direction, and at the same time distributes the force, so that the limiting structure 03 is more stably positioned on the side end wall 22.

[0086] Optionally, as shown in Figure 9, a fourth fastener 011 is provided on the side end wall 22, which fixes the limiting structure 03 to the side end wall 22. The third limiting groove 222 can distribute the force on the fourth fastener 011. The fourth fastener 011 can be, but is not limited to, a screw.

[0087] As an optional example, there are two fourth fasteners 011, with the two fourth fasteners 011 located on the front and rear sides of the third limiting groove 222 respectively, and the fourth fasteners 011 fixing the fourth fasteners 011 to the side wall 22.

[0088] Optionally, to facilitate the assembly of the limiting structure 03, the third limiting groove 222 is a strip-shaped groove extending in the vertical direction. During installation, the protrusion 032 of the limiting structure 03 can slide upward along the third limiting groove 222 until the assembly position.

[0089] In some optional embodiments, referring to Figures 10 and 11, mounting holes 221 are provided on both side end walls 22, and bushings 6 are provided on both mounting holes 221. Bushing fasteners 010 are provided on the bushings 6, locking the bushings 6 to the side end walls 22. Optionally, a limiting structure 03 is located at the bottom of the bushing 6, and the shape of the top of the limiting structure 03 is adapted to the shape of the bushing 6, making the overall structure compact and reducing space occupation. The top of the limiting structure 03 can provide partial support for the bushing 6. A clearance groove 033 may be provided on the top of the limiting structure 03 to allow the bushing fasteners 010 to enter.

[0090] In some optional embodiments, as shown in FIG9, a first positioning groove is recessed on the first rotating shaft 3. The shape of the first positioning groove is adapted to the first swing member 04. The first swing member 04 is inserted into the first positioning groove. A third fastener 08 is provided on the first rotating shaft 3, and the third fastener 08 fixes the first swing member 04 in the first positioning groove. The first positioning groove is used to limit the first swing member 04, distribute the force, and prevent the first swing member 04 from being loosened or detached due to impact when it abuts against the first baffle 0311 and the second baffle 0312, thereby improving the stability and reliability of the first swing member 04.

[0091] Furthermore, the first swaying component 04 is welded to the edge of the first positioning groove to enhance stability and increase load-bearing strength. The third fastener 08 can also be connected to the first rotating shaft 3 by electric welding to prevent the third fastener 08 from rotating and loosening, making it safer and more reliable.

[0092] [Correction based on Details 91, 28.09.2025] In some optional embodiments, please refer to Figures 9 and 10. A first swaying member 04 is provided on the first rotating shaft 3, and a bearing 06 is provided on the first swaying member 04. The bearing 06 includes a bearing outer ring 061 and a bearing inner ring 062 that can rotate relative to each other. The bearing outer ring 061 is connected to the first swaying member 04. The end of the vehicle head body 01 facing the first rotating shaft 3 has a second rotating shaft 12, which is inserted into the bearing inner ring 062. In this way, the second rotational degree of freedom of the vehicle head body 01 can be realized. The vehicle head body 01 can swing left and right with the second rotating shaft 12 as the pivot. The first rotational degree of freedom is to pitch and swing with the first rotating shaft 3. When the vehicle head structure moves on uneven ground, the vehicle head body 01 can swing left and right and up and down under the action of external force to adapt to different terrains, further improving the adaptability of the vehicle head body 01 to ground undulations.

[0093] Furthermore, the second swaying component 07 is welded to the edge of the second positioning groove 121 to enhance stability and increase load-bearing strength. The fifth fastener 012 can also be connected to the second rotating shaft 12 by electric welding to prevent the fifth fastener 012 from rotating and loosening, making it safer and more reliable.

[0094] In some alternative embodiments, a third baffle 06111 and a fourth baffle 06121 are formed circumferentially on the outer ring 061 of the bearing. A second oscillating member 07 is provided on the second rotating shaft 12, and the second oscillating member 07 is located between the third baffle 06111 and the fourth baffle 06121. The third baffle 06111 and the fourth baffle 06121 cooperate to limit the rotation range of the second oscillating member 07.

[0095] Similarly, in this embodiment, the rotation amplitude of the second swinging member 07 is limited by the third baffle 06111 and the fourth baffle 06121, thereby limiting the rotation amplitude of the front body 01 in the left and right swinging directions. The first baffle 0311 and the second baffle 0312 limit the rotation amplitude of the front body 01 in the pitch swinging direction. Since the degree of undulation of the ground is limited, it is not necessary for the front body 01 to swing a large amplitude to adapt. Therefore, by limiting the rotation amplitude of the front body 01, the need for the front body 01 to adapt to undulating ground can be met, while avoiding large rotation of the front body 01 relative to the body 10. Furthermore, the front body 01 and the body 10 can be kept separate in the left and right swinging directions, while reducing the clearance space 09 required between them, narrowing the gap between the front body 01 and the body 10, and avoiding the situation where the overall size of the garden robot is too large.

[0096] Optionally, to accommodate most ground undulations while ensuring a small clearance space 09, the angle between the third barrier 06111 and the fourth barrier 06121 is between 20 and 40 degrees; preferably, the angle between the third barrier 06111 and the fourth barrier 06121 is 30 degrees. In some optional embodiments, with the initial position of the second swing member 07 at zero degrees, the second swing member 07 can rotate within a range of ±15 degrees.

[0097] In some alternative embodiments, as shown in FIG12, a second positioning groove 121 is recessed on the second rotating shaft 12. The shape of the second positioning groove 121 is adapted to the second swing member 07. The second swing member 07 is inserted into the second positioning groove 121. A fifth fastener 012 is provided on the second rotating shaft 12. The fifth fastener 012 fixes the second swing member 07 in the second positioning groove 121.

[0098] The second positioning groove 121 is used to limit the second swing member 07, distribute the force, and prevent the second swing member 07 from being loosened or detached due to impact when it abuts against the third baffle 06111 and the fourth baffle 06121, thereby improving the stability and reliability of the second swing member 07.

[0099] In some alternative embodiments, two protrusions are formed on the outer ring 061 of the bearing along the axial direction, with a gap between the two protrusions. The gap between the two protrusions forms a second limiting groove 0611. The second oscillating member 07 is located in the second limiting groove 0611. The two groove walls of the second limiting groove 0611 in the circumferential direction are the third baffle 06111 and the fourth baffle 06121.
