[0022] The following specific implementation manner will further illustrate the present utility model in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0023] The following embodiments of the present invention are described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, "connection" can be detachably connected or non-detachably connected; it can be directly connected or indirectly connected through an intermediate medium. Among them, "fixed connection" can be connected to each other and the relative position relationship after connection remains unchanged. "Rotational connection" can be connected to each other and can rotate relative to each other after connection. The term "integrated molding" means that in the process of forming one of the multiple components, the component is connected to other components, and there is no need to connect the two components together by reprocessing (such as bonding, welding, snap connection, screw connection). The orientation terms mentioned in the embodiments of the present utility model, such as "top", "bottom", "inside", "outside", "side", etc., are only reference directions of the drawings. Therefore, the orientation terms used are for better and clearer explanation and understanding of the embodiments of the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present utility model.

The driving wheel can drive the walking wheel 200 to rotate through a driving motor independent of the walking wheel 200.

[0027] The operating equipment 1000 can be configured as, but not limited to, mowing equipment, pesticide spraying equipment, crop harvesting equipment, sweeping equipment, transportation equipment, and the like. In the present embodiment, the operating equipment 1000 can be configured as mowing equipment. The operating equipment 1000 includes a cutting mechanism 300 disposed on the chassis 100. The cutting mechanism 300 is used to trim the lawn or other vegetation. The chassis lifting mechanism 500 can be adjusted by lifting the chassis 100 to drive the cutting mechanism 300 to lift and lower, thereby meeting the requirements of the mowing height. Of course, in some embodiments, the operating equipment 1000 can also be, but not limited to, a sweeper or other intelligent devices.

[0028] It should be noted that Figure 1 The purpose is only to schematically describe the arrangement between the chassis 100 and the chassis lifting mechanism 500, and is not to specifically limit the connection position, connection relationship and specific structure of each component. Figure 1 The structure of the operating device 1000 is only shown in the embodiment of the present invention, and does not constitute a specific limitation on the operating device 1000. In other embodiments of the present invention, the operating device 1000 may include Figure 1 More or fewer components, or a combination of certain components, or different components as shown, for example, the working equipment 1000 may also include but is not limited to a cutting mechanism 300, a safety protection structure, and the like.

[0029] Please also read Figure 1 and Figure 2 , Figure 2 yes Figure 1 Exploded view of the operating equipment 1000 in the embodiment of the utility model. The chassis lifting mechanism 500 provided in the embodiment of the utility model is applied to the operating equipment 1000. The chassis lifting mechanism 500 includes a first lifting mechanism 10 and a driving mechanism 20. The first lifting mechanism 10 is arranged on the chassis 100 to drive the chassis 100 to be lifted and lowered relative to the ground. The driving mechanism is laterally arranged on the chassis 100 along the front-to-back direction X of the operating equipment 1000. The driving mechanism 20 includes a driving member 21 and a first transmission member 22, the first transmission member 22 is spaced apart from the driving member 21 in the left-right direction Y of the operating equipment 1000, one end of the first transmission member 22 is connected to the driving member 21, and the other end of the first transmission member 22 is connected to the first lifting mechanism 10, and the driving member 21 is used to push and pull the first transmission member 22 in the front-to-back direction X of the operating equipment 1000 to drive the first lifting mechanism 10 to move.

[0030] The working equipment 1000 provided by the utility model, on the one hand, is based on the drive mechanism 20 being transversely arranged on the chassis 100 along the front-rear direction X of the working equipment 1000, the first transmission member 22 is spaced apart from the drive member 21 in the left-right direction Y of the working equipment 1000, one end of the first transmission member 22 is connected to the drive member 21, and the other end of the first transmission member 22 is connected to the first lifting mechanism 10, and the drive member 21 is used to push and pull the first transmission member 22 in the front-rear direction X of the working equipment 1000 to drive the first lifting mechanism 10 to move, so that the structure of the working equipment 1000 is compact, the drive mechanism 20 has strong tensile and compressive resistance, and the gravity stress of the working equipment 1000 acting on the drive mechanism 20 is reduced to prevent the drive mechanism 20 from being damaged, thereby extending the service life of the drive mechanism 20; on the other hand, based on the first lifting mechanism 10 being arranged on the chassis 100 to drive the chassis 100 to rise and fall relative to the ground, the working equipment 1000 can meet the walking requirements of different working conditions.

[0031] For the accuracy of description, please refer to the directions in this article. Figure 1 For reference, the term "front-to-back direction X" refers to the direction of travel of the working equipment 1000, that is, the arrangement direction of the front and rear wheels in the working equipment 1000 (where the positive direction of the X axis is the front). The term "left-right direction Y" refers to the arrangement direction of the left and right wheels in the working equipment 1000 (where the positive direction of the Y axis is the right). The term "height direction Z" refers to the arrangement direction of the wheels of the working equipment 1000 that are against the support plane and the highest protruding part of the working equipment 1000, that is, the up and down direction (where the positive direction of the Z axis is up). Among them, the front-to-back direction X, the left-to-right direction Y and the height direction Z together constitute the three orthogonal directions of the working equipment 1000. For the convenience of description, the up and down, left-to-right, and front-to-back directions in the utility model are relative positions and do not constitute a limitation to the implementation. The front-to-back direction X, the left-to-right direction Y and the height direction Z of the working equipment 1000 can be customized according to the specific structure of the product and the perspective of the drawings, and the utility model does not make specific limitations.

[0032] In some embodiments, in the front-to-back direction X of the working equipment 1000, the first lifting mechanism 10 is disposed at one of the front and rear ends of the chassis 100, thereby reducing the space occupied by the first lifting mechanism 10 on the working equipment 1000, making the structure compact and saving production costs. Of course, in some other embodiments, in the front-to-back direction X of the working equipment 1000, the first lifting mechanism 10 can also be disposed at the front and rear ends of the chassis 100, thereby improving the flexibility and reliability of the chassis 100 of the working equipment 1000 for lifting and lowering, thereby enabling the working equipment 1000 to adapt to the walking requirements of more complex working conditions.

[0033] Please also read Figure 2 and Figure 3, Figure 3 yes Figure 2 1000 of the operating equipment 1000. Exemplarily, in the present embodiment, in the front-rear direction X of the operating equipment 1000, the first lifting mechanism 10 is arranged at the rear end of the chassis 100. Exemplarily, in the present embodiment, the driving member 21 is configured as an electric push rod structure. Specifically, the driving member 21 includes a driving motor 211 and a push rod 212. In some embodiments, the driving member 21 can also be configured as a screw nut structure, a gear rack structure or a cylinder structure. When the driving member 21 is configured as a screw nut structure, the driving member 21 includes a screw and a nut matched with the screw. In other embodiments, when the driving member 21 is configured as a gear rack structure, the driving member 21 includes a rack and a gear matched with the rack. In other embodiments, when the driving member 21 is configured as a cylinder structure, the driving member 21 includes a piston rod and a cylinder body, and the piston rod is telescopically arranged in the cylinder body.

[0034] In some embodiments, the driving member 21 further includes a guide seat 213, and the guide seat 213 is provided with a guide groove along the front-rear direction X of the working equipment 1000, and the push rod 212 is movably arranged in the guide groove. Thus, the guide seat 213 can guide and support the movement of the push rod 212, thereby preventing the push rod 212 from deforming, protecting the push rod 212, and extending the service life of the driving mechanism 20. The guide seat 213 is fixedly connected to the chassis 100, thereby improving the stability and reliability of the connection between the driving mechanism 20 and the chassis 100, and ensuring the smoothness and stability of the drive motor 211 driving the push rod 212 to perform telescopic activities.

[0035] In some embodiments, the driving member 21 also includes a connecting seat 215, which is configured to be fixedly connected to the chassis 100, thereby improving the stability and reliability of the connection between the connecting seat 215 and the chassis 100, and ensuring the smoothness and stability of the driving motor 211 driving the push rod 212 to perform telescopic activities.

[0036] One end of the push rod 212 is connected to the drive motor 211, and the other end of the push rod 212 is connected to the first transmission member 22. The drive motor 211 is used to drive the push rod 212 to push and pull the first transmission member 22 along the front-back direction X of the working equipment 1000, and the connection point between the push rod 212 and the drive motor 211 is located between the connection point between the push rod 212 and the first transmission member 22 and the connection point between the first transmission member 22 and the first lifting mechanism 10. Therefore, since the grass collecting device is provided at the rear of the working equipment 1000, the gravity stress on the walking wheel 200 located at the rear end of the working equipment 1000 is greater than that on the walking wheel 200 located at the front end of the working equipment 1000; by setting the output end of the driving member 21 at the front end of the working equipment 1000, the length of the hinge points at both ends of the first transmission member 22 can be increased, so as to reduce the angle between the hinge points at both ends of the first transmission member 22 and the telescopic direction F of the push rod 212, so as to increase the stress in the horizontal direction and reduce the stress in the vertical direction. On the one hand, the utilization rate of the driving force applied by the push rod 212 to the first transmission member 22 is improved; on the other hand, the supporting force of the ground on the walking wheel 200 is transmitted to the first lifting mechanism 10 through the first lifting mechanism 10. The force is then transmitted to the push rod 212 by the first transmission member 22. Since the angle between the telescopic direction F of the push rod 212 and the transmission direction of the first transmission member 22 is relatively small, most of the supporting force of the ground on the walking wheel 200 acts on the push rod 212 along the telescopic direction F parallel to the push rod 212. Furthermore, the driving mechanism 20 and the first transmission member 22 are spaced apart along the left-right direction Y of the operating equipment 1000 and placed horizontally, so that the push rod 212 can telescope along the front-back direction X of the operating equipment 1000, thereby making the structure compact and making the push rod 212 have strong tensile and compressive resistance, thereby preventing the driving mechanism 20 from being damaged, thereby extending the service life of the driving mechanism 20.

[0037] The driving motor 211 is used to drive the push rod 212 to perform telescopic movement along the front-to-back direction X of the working equipment 1000. The telescopic direction F of the push rod 212 is parallel or colinear with the extension direction of the push rod 212, and is parallel to the front-to-back direction X of the working equipment 1000, so that the driving motor 211 has strong tensile and compressive resistance. Exemplarily, in this embodiment, the driving motor 211 is arranged on the side close to the first lifting mechanism 10 relative to the push rod 212, so that the input end of the push rod 212 is arranged closer to the first lifting mechanism 10 than the output end of the push rod 212. The telescopic direction F of the push rod 212 is parallel to the front-to-back direction X of the working equipment 1000, so as to facilitate the installation of the driving mechanism 20, and simplify the calculation of the transmission parameters of the first transmission member 22 and the first lifting mechanism 10, so as to facilitate the driving mechanism 20 to accurately control the lifting height of the chassis 100.

[0038] The two ends of the first transmission member 22 are respectively hinged to the driving member 21 and the first lifting mechanism 10. It should be noted that the term "hinged" includes two elements being pivotally connected or two elements being spherically connected. For example, in this embodiment, the two ends of the first transmission member 22 are respectively pivotally connected to the first lifting mechanism 10 and the push rod 212. Specifically, the first transmission member 22, the first lifting mechanism 10 and the push rod 212 are respectively provided with pivot holes for the pivot shaft to pass through, so that the first transmission member 22, the first lifting mechanism 10 and the push rod 212 can rotate around the central axis of the pivot shaft. The central axis of the pivot shaft is parallel to the left-right direction Y of the operating equipment 1000. Of course, in some embodiments, the pivot shaft can be fixed to the first transmission member 22 and rotatably penetrated on the first lifting mechanism 10 and the push rod 212; or, the pivot shaft can be fixed to the first lifting mechanism 10 and the push rod 212 and rotatably penetrated on the first transmission member 22, thereby simplifying the assembly operation of the pivot shaft.

[0039] In some embodiments, the two ends of the first transmission member 22 are respectively connected to the first lifting mechanism 10 and the push rod 212 by ball joints. The first transmission member 22 is provided with a spherical protrusion, and the first lifting mechanism 10 and the push rod 212 are provided with a spherical groove that matches the spherical protrusion; or, the first transmission member 22 is provided with a spherical groove, and the first lifting mechanism 10 and the push rod 212 are provided with a spherical protrusion that matches the spherical groove. The spherical protrusion is rotatably accommodated in the spherical groove. The first transmission member 22, the first lifting mechanism 10 and the push rod 212 can respectively rotate in any direction around the center of the spherical protrusion. In some cases, when the operating equipment 1000 is disturbed by external interference, causing the output direction of the driving force of the driving mechanism 20 to deflect, the ball joint connection between the first transmission member 22 and the first lifting mechanism 10 and the push rod 212 can keep the first transmission member 22 and the first lifting mechanism 10 and the push rod 212 in normal connection, so that the chassis lifting mechanism 500 can still work normally, improve the anti-interference ability of the chassis lifting mechanism 500, and simplify the structure of the chassis lifting mechanism 500 for easy assembly. Of course, in other embodiments, one end of the first transmission member 22 is connected to the first lifting mechanism 10 by a ball joint, and the other end of the first transmission member 22 is pivotally connected to the push rod 212; or, one end of the first transmission member 22 is connected to the push rod 212 by a ball joint, and the other end of the first transmission member 22 is pivotally connected to the first lifting mechanism 10.

[0040] In some embodiments, the chassis lifting mechanism 500 of the operating equipment 1000 further includes a second lifting mechanism 50. The driving mechanism 20 further includes a second transmission member 23. One end of the second transmission member 23 is connected to the driving member 21, and the other end of the second transmission member 23 is connected to the second lifting mechanism 50. The two ends of the second transmission member 23 are respectively hinged to the driving member 21 and the second lifting mechanism 50. Specifically, one end of the second transmission member 23 can also be ball-jointed and / or pivotally connected to the second lifting mechanism 50, and the other end of the second transmission member 23 can also be ball-jointed and / or pivotally connected to the push rod 212.

[0041] Please also read Figure 2 and Figure 4 , Figure 4 yes Figure 2 1 is a side view of the chassis lifting mechanism 500 of the working equipment 1000. Along the front-to-rear direction X of the working equipment 1000, the first lifting mechanism 10 is arranged at the rear end of the chassis 100, and the second lifting mechanism 50 is arranged at the front end of the chassis 100. The distance from the connection point of the first transmission member 22 and the driving member 21 to the connection point of the first transmission member 22 and the first lifting mechanism 10 is the first distance D1. The distance from the connection point of the second transmission member 23 and the driving member 21 to the connection point of the second transmission member 23 and the second lifting mechanism 50 is the second distance D2, wherein the second distance D2 is smaller than the first distance D1. Therefore, on the one hand, the first lifting mechanism 10 and the second lifting mechanism 50 share a driving mechanism 20, which improves the compactness of the lifting 500 and reduces the cost; on the other hand, when the grass collecting device is provided at the rear end of the operating equipment 1000, the center of gravity of the operating equipment 1000 is closer to the first lifting mechanism 10, and the gravity stress applied by the chassis 100 to the first lifting mechanism 10 is greater than the gravity stress applied by the chassis 100 to the second lifting mechanism 50, and the force exerted by the first transmission member 22 on the push rod 212 is greater than the force exerted by the second transmission member 23 on the push rod 212, and the vertical component of the first transmission member 22 acting on the push rod 212 is too large, which can easily form a torque on the push rod 212, causing damage to the driving member 21 Therefore, the embodiment of the utility model arranges the output end of the push rod 212 to be arranged close to one side of the second lifting mechanism 50, and arranges the distance from the hinge point of the second transmission member 23 and the push rod 212 to the second lifting mechanism 50 to be smaller than the distance from the hinge point of the first transmission member 22 and the push rod 212 to the first lifting mechanism 10, so as to extend the length of the two hinge points of the first transmission member 22 and the push rod 212 and the first lifting mechanism 10, thereby increasing the horizontal component of the first transmission member 22 and reducing the vertical component of the first transmission member 22, thereby improving the utilization rate of the driving force of the driving mechanism 20, reducing the load of the driving mechanism 20, preventing the driving mechanism 20 from being damaged, and extending the service life of the chassis lifting mechanism 500.

[0042] The walking wheel 200 includes a first wheel 210 and a second wheel 220. For example, in this embodiment, the number of the first wheels 210 includes two and serves as the rear wheels of the working device 1000, and the number of the second wheels 220 includes two and serves as the front wheels of the working device 1000. Both ends of the first lifting mechanism 10 are connected to the first wheels 210, respectively, and both ends of the second lifting mechanism 50 are connected to the second wheels 220, respectively.

[0043] The second transmission member 23 is spaced apart from the driving member 21 in the left-right direction Y of the operating device 1000. Exemplarily, in this embodiment, the first transmission member 22, the push rod 212 and the second transmission member 23 are arranged along the left-right direction Y of the operating device 1000. Thus, based on the first transmission member 22 and the second transmission member 23 being located on different sides of the push rod 212, interference between the first transmission member 22 and the second transmission member 23 during the transmission process is avoided. Of course, in some embodiments, the first transmission member 22 and the second transmission member 23 are located on the same side of the push rod 212, and the utility model does not make specific limitations.

[0044] The first transmission member 22, the push rod 212 and the second transmission member 23 can be pivotally connected by one or more pivotal members. The pivotal member can be configured as an elastic member. Therefore, on the one hand, since the pivotal member is provided with an elastic member, the pivotal member generates a certain elastic deformation when subjected to external vibration or impact, thereby reducing the impact of vibration and impact on the driving member 21 and the transmission member 23, protecting the normal operation of the driving member 21, and improving the service life of the driving mechanism 20 and the driving stability of the operating equipment 1000; on the other hand, the driving mechanism 20 does not need to be provided with additional elastic members, which simplifies the overall structure of the driving mechanism 20, makes the structure compact and reduces the cost. Specifically, in this embodiment, the pivotal member can be, but is not limited to, a pin, a rivet, etc.

[0045] Specifically, exemplarily, in the present embodiment, the pivotal member can be configured as a flexible shaft, whereby the material of the pivotal member can absorb and buffer the rigid stress transmitted by the first lifting mechanism 10 and the second lifting mechanism 50 when elastic deformation occurs. The material of the pivotal member may include but is not limited to silicone, rubber, etc. Of course, in some embodiments, the pivotal member includes a pivotal body and an elastic member disposed on the pivotal body, and the material of the pivotal body includes but is not limited to metal, alloy, etc. The pivotal body can be configured as a rigid structure. Thus, the pivotal body can increase the rigidity of the pivotal member to meet the requirements of a high-precision transmission system and increase the service life of the pivotal member. For example, the pivotal member can be configured as but is not limited to an elastic pin coupling.

[0046] At least one of the first transmission member 22 and the second transmission member 23 is provided with an elastic member. For example, in this embodiment, the first transmission member 22 is provided with an elastic member. Of course, in some embodiments, the second transmission member 23 may also be provided with an elastic member; or, the first transmission member 22 and the second transmission member 23 are both provided with elastic members. As a result, the first transmission member 22 and / or the second transmission member 23 provided with elastic members can absorb the rigid stress transmitted to the first transmission member 22 and / or the second transmission member 23 by the swing structure, thereby improving the service life of the drive mechanism 20 and improving the driving stability of the operating equipment 1000. The first transmission member 22 and the second transmission member 23 are configured as rigid members, so as to facilitate the assembly of the first transmission member 22 and the second transmission member 23 with the drive member 21, the first lifting mechanism 10 and the second lifting mechanism 50, and ensure that the first transmission member 22 and the second transmission member 23 can transmit the driving force applied by the drive member 21 to the first lifting mechanism 10 and the second lifting mechanism 50, so as to realize that the first lifting mechanism 10 and the second lifting mechanism 50 drive the chassis 100 to rise and fall. The elastic member is configured as at least one of a spring, a spring sheet, an elastic body and a gas spring. For example, the elastic member can be disposed on at least one of the first transmission part 221 and the second transmission part 222, and the elastic member can be disposed on at least one of the first transmission section 231, the second transmission section 232 and the third transmission section 233.

[0047] Please also read Figure 2 and Figure 5 , Figure 5 It is a schematic diagram of the structure of the operating equipment 1000 provided in the second embodiment of the utility model. In the second embodiment, the structure of the operating equipment 1000 is similar to that of the operating equipment 1000 in the first embodiment, except that the second transmission member 23 is spaced apart from the driving member 21 in the front-rear direction X of the operating equipment 1000, so that the first transmission member 22 and the second transmission member 23 are independently arranged, which is convenient for assembly, maintenance and other operations between the first transmission member 22 and the second transmission member 23, and avoids interference between the first transmission member 22 and the second transmission member 23 during the transmission process. The driving mechanism 20 includes two first transmission members 22, and the driving member 21 is arranged between the two first transmission members 22 in the left-right direction Y of the operating equipment 1000. As a result, the stability and reliability of the first lifting mechanism 10 driving the chassis 100 to rise and fall are improved, thereby improving the height adjustment accuracy of the operating equipment 1000 and improving the stability of the lifting, and the structural layout is reasonable.

[0048] It should be noted that the other structures of the operating equipment 1000 in the second embodiment can refer to the specific details of the operating equipment 1000 in the first embodiment, which will not be repeated here.

[0049] In the present embodiment, the driving mechanism 20 further includes a pivot seat 26. The pivot seat 26 is disposed on the driving member 21, and the second transmission member 23 is pivotally connected to the driving member 21 through the pivot seat 26. Thus, the pivot seat 26 provides a mounting site for the second transmission member 23, thereby improving the reliability and stability of the connection between the second transmission member 23 and the driving member 21. Specifically, the pivot seat 26 is fixed to the end of the push rod 212 facing away from the driving motor 211. The pivot seat 26 includes a first pivot portion 261 and a second pivot portion 262. The driving mechanism 20 further includes a pivot member 25. The pivot member 25 includes a first pivot shaft 251 and a second pivot shaft 252. The first pivot portion 261 is fixed to the end of the push rod 212 facing away from the driving motor 211, and is used to be pivotally connected to the first transmission member 22 through the first pivot shaft 251. The second pivoting portion 262 is arranged to protrude toward the second transmission member 23 relative to the first pivoting portion 261, and is used to be pivotally connected to the second transmission member 23 through the second pivoting shaft 252. The first pivoting shaft 251 and the second pivoting shaft 252 are arranged independently of each other. Therefore, on the one hand, based on the transmission connection between the first transmission member 22 and the second transmission member 23 and the driving member 21 through different pivoting members 25, the height adjustment accuracy of the operating equipment 1000 is improved, and the stability of lifting is improved; on the other hand, the durability of the first pivoting shaft 251 and the second pivoting shaft 252 is improved, and the structural layout is reasonable.

[0050] At least one of the first pivot axis 251 and the second pivot axis 252 is configured as a flexible axis. For example, in this embodiment, both the first pivot axis 251 and the second pivot axis 252 are configured as flexible axes, so that the first pivot axis 251 can absorb the rigid stress transmitted from the first lifting mechanism 10 to the first transmission member 22, and the second pivot axis 252 can absorb the rigid stress transmitted from the second lifting mechanism 50 to the second transmission member 23, thereby improving the service life of the driving member 21 and improving the driving stability of the operating equipment 1000. Of course, in some embodiments, one of the first pivot axis 251 and the second pivot axis 252 can be configured as a flexible axis, and the other of the first pivot axis 251 and the second pivot axis 252 can be configured as a rigid axis.

[0051] For example, in this embodiment, both first transmission members 22 are provided with elastic members, thereby further improving the buffering capacity of the elastic members to the rigid force transmitted by the first lifting mechanism 10. The two first transmission members 22 are pivotally connected through the same pivot member 25; or, the two first transmission members 22 can also be pivotally connected through different pivot members 25. Of course, in some embodiments, one of the two first transmission members 22 is provided with an elastic member. It should be noted that the number of the first transmission members 22 can also be one, three, or more than three, which is not specifically limited in the present invention.

[0052] Please refer again Figure 2 and Figure 3 The first lifting mechanism 10 includes a first swing arm 13 and a first rotating shaft 12. The first rotating shaft 12 is spaced apart from the first wheel axle 11. The central axis of the first rotating shaft 12 and the central axis of the first wheel axle 11 are both parallel to the left-right direction Y of the working equipment 1000. The first swing arm 13 is connected with the first wheel axle 11 and the first rotating shaft 12 to form an integral structure. The first wheel axle 11 is coaxially arranged with the first wheel 210, and the first rotating shaft 12 is eccentrically arranged with the first wheel 210.

[0053] Exemplarily, in this embodiment, the first lifting mechanism 10 further includes a connecting arm 14. The connecting arm 14 and the first swing arm 13 are independently arranged and spaced apart from each other. One end of the connecting arm 14 is connected to the first transmission member 22, and the other end of the connecting arm 14 is connected to the first rotating shaft 12. One end of the first swing arm 13 is connected to the first rotating shaft 12, and the other end of the first swing arm 13 is fixedly connected to the first wheel shaft 11. Exemplarily, in this embodiment, the connecting arm 14 and the first transmission member 22 can be pivotally connected. The connecting arm 14 and the first swing arm 13 are both fixedly connected to the first rotating shaft 12. Of course, in some embodiments, the connecting arm 14 and the first transmission member 22 can also be connected by a ball joint. The connecting arm 14 and / or the first swing arm 13 are both rotatably connected to the first rotating shaft 12. The driving motor 211 is used to drive the push rod 212 to pull or push the first transmission member 22, so that the connecting arm 14 drives the first rotating shaft 12 to rotate, and the first rotating shaft 12 drives the first swing arm 13 to rotate around the central axis of the first wheel shaft 11. The connecting arm 14 and the first swing arm 13 are configured as a rod-shaped structure. There are two first swing arms 13, and the two first swing arms 13 are connected to opposite ends of the first rotating shaft 12. Of course, in some embodiments, there can also be one first swing arm 13.

[0054] In some embodiments, the first lifting mechanism 10 further includes a bearing seat 15. The first rotating shaft 12 is connected to the chassis 100 through the bearing seat 15. Specifically, the bearing seat 15 is fixed to the chassis 100, and the first rotating shaft 12 is rotatably arranged on the bearing seat 15. Thus, the first rotating shaft 12 is rotatably arranged relative to the chassis 100 through the bearing seat 15 to reduce the rotation resistance of the first rotating shaft 12. Exemplarily, in this embodiment, the bearing seat 15 is arranged close to the end of the first rotating shaft 12, so as to facilitate the assembly of the chassis 100 and the bearing seat 15, and avoid the problem of distortion and deformation of the chassis 100 during the process of adjusting the ground clearance.

[0055] Please refer again Figure 3 and Figure 6 , Figure 6 yes Figure 31 is an exploded view of the second lifting mechanism 50 of the operating equipment 1000 in FIG. The second lifting mechanism 50 includes a second wheel axle 51, a second rotating shaft 52 and a second swing arm 53. The second swing arm 53 is connected to the second wheel axle 51 and the second rotating shaft 52, and the second rotating shaft 52 is used to connect to the chassis 100. The end of the second transmission member 23 facing away from the push rod 212 is connected to the second swing arm 53. The second transmission member 23, the second wheel axle 51 and the second rotating shaft 52 are arranged in pairs. The driving mechanism 20 is used to drive the second swing arm 53 to rotate around the central axis of the second rotating shaft 52, so that the second swing arm 53 drives the second wheel axle 51 to rotate around the second rotating shaft 52. In this way, the second swing arm 53 is eccentrically arranged relative to the second rotating shaft 52, and the second push rod 212 is driven by the driving mechanism 20 to pull or push the second swing arm 53 to drive the second wheel axle 51 to rotate around the central axis of the second rotating shaft 52, so that the height of the chassis 100 from the ground can be adjusted. When the second axle 51 rotates relative to the second rotation axis 52 toward the side close to the ground, the second rotation axis 52 drives the chassis 100 to move in a direction away from the ground, so that the height of the chassis 100 from the ground increases. When the second axle 51 rotates relative to the second rotation axis 52 toward the side away from the ground, the second rotation axis 52 drives the chassis 100 to move in a direction close to the ground, so that the height of the chassis 100 from the ground decreases. In addition, when the driving mechanism 20 drives the second swing arm 53 to drive the second axle 51 to rotate around the second rotation axis 52, the distance between the second axle 51 and the center of gravity of the working equipment 1000 along the front-rear direction X of the working equipment 1000 can also be adjusted. For example, when the second axle 51 rotates toward the direction approaching the center of gravity of the working equipment 1000, the distance between the second axle 51 and the center of gravity of the working equipment 1000 along the front-rear direction X of the working equipment 1000 is reduced, so that the mass distribution of the working equipment 1000 can be concentrated toward the center of gravity, the rotational inertia of the working equipment 1000 is reduced, the rotational resistance of the working equipment 1000 when rotating is reduced, the turning radius of the working equipment 1000 is reduced, and the flexibility of the working equipment 1000 is improved. For another example, when the second axle 51 rotates toward the direction away from the center of gravity of the working equipment 1000, the distance between the second axle 51 and the center of gravity of the working equipment 1000 along the front-rear direction X of the working equipment 1000 is increased, so that the driving stability of the working equipment 1000 can be increased. In some cases, when a grass collector for collecting grass clippings, fallen leaves and other debris is installed on the rear side of the working equipment 1000, the second wheel axle 51 moves away from the center of gravity of the working equipment 1000, and the overall center of gravity of the working equipment 1000 can also be moved away from the grass collector, thereby increasing the load capacity of the working equipment 1000, increasing the collection capacity of the grass collector, and reducing the risk of the working equipment 1000 tilting.

[0056] It should be noted that, in this embodiment, the distance from the hinge point of the first transmission member 22 and the push rod 212 to the first lifting mechanism 10 refers to the distance from the hinge point of the first transmission member 22 and the push rod 212 to the center of the first rotation axis 12 on the projection plane perpendicular to the left-right direction Y of the working device 1000. The distance from the hinge point of the second transmission member 23 and the push rod 212 to the second lifting mechanism 50 refers to the distance from the hinge point of the second transmission member 23 and the push rod 212 to the center of the second rotation axis 52 of the second lifting mechanism 50 on the projection plane perpendicular to the left-right direction Y of the working device 1000.

[0057] The length of the first transmission member 22 in the front-to-back direction X of the working device 1000 is greater than the length of the second transmission member 23 in the front-to-back direction X of the working device 1000. The length of the first transmission member 22 in the front-to-back direction X of the working device 1000 refers to the distance between the two ends of the first transmission member 22 on the projection plane perpendicular to the working device 1000. The length of the second transmission member 23 in the front-to-back direction X of the working device 1000 refers to the distance between the two ends of the second transmission member 23 on the projection plane perpendicular to the working device 1000.

[0058] In this embodiment, the hinge point between the first transmission member 22 and the push rod 212 coincides with the hinge point between the second transmission member 23 and the push rod 212. Therefore, on the one hand, it is convenient to assemble the push rod 212 with the first transmission member 22 and the second transmission member 23; on the other hand, it is convenient to calculate the relationship between the telescopic distance of the push rod 212 and the transmission parameter of the first transmission member 22, thereby improving the accuracy of the chassis lifting mechanism 500 in adjusting the ground clearance of the chassis 100; on the other hand, the output end of the push rod 212 has good structural strength, making the overall structure of the chassis lifting mechanism 500 more compact. Of course, in some embodiments, the hinge point between the first transmission member 22 and the push rod 212 may not coincide with the hinge point between the second transmission member 23 and the push rod 212.

[0059] Of course, in some embodiments, the number of the driving mechanisms 20 includes two, one of which is connected to the first lifting mechanism 10 and is used to drive the first lifting mechanism 10 to rise and fall, and the other is connected to the second lifting mechanism 50 and is used to drive the second lifting mechanism 50 to rise and fall. In this way, the two driving mechanisms 20 can independently drive the first transmission member 22 and the second transmission member 23, so that the lifting height of the first lifting mechanism 10 and the second lifting mechanism 50 can be adjusted separately, thereby improving the height of the chassis 100 from the ground and the flexibility of adjusting the rotational inertia of the working equipment 1000.

[0060] The second wheel 220 is connected to the second axle 51. For example, in this embodiment, the number of the second axles 51 is two, and the two ends of each second axle 51 are respectively connected to the second swing arm 53 and the second wheel 220. The number of the second swing arms 53 is two. The two second swing arms 53 are independently provided and spaced apart from each other. The second rotating shaft 52 is connected between the two second swing arms 53. Of course, in some embodiments, the two second swing arms 53 can also be independently provided and fixedly connected to each other; or, the two second swing arms 53 are integrated into an integral structure. The second axle 51 and the second swing arm 53 can also be rotatably connected or fixedly connected. The second transmission member 23 is hinged to the second swing arm 53.

[0061] The second lifting mechanism 50 also includes a first sliding member 541. The first sliding member 541 is connected to the second swing arm 53. The driving mechanism 20 is used to drive the second transmission member 23 to push or pull the first sliding member 541 to move along the front-rear direction X of the working equipment 1000, so that the first sliding member 541 drives the second swing arm 53 to rotate around the central axis of the second rotating shaft 52. The first sliding member 541 is connected to the two second swing arms 53 at two opposite ends along the axial direction, so that the driving mechanism 20 can drive the two second swing arms 53 to rotate synchronously through the first sliding member, simplifying the connection between the driving mechanism 20 and the two second swing arms 53. Among them, the first sliding member and the second swing arm 53 can be rotatably connected or fixedly connected.

[0062] The chassis lifting mechanism 500 further includes a mounting base 56, a second sliding member 542 and a guide rod 57. The mounting base 56 is fixedly arranged relative to the chassis 100. An accommodating space 5601 is arranged on the mounting base 56. The first sliding member 541, the second sliding member 542 and the guide rod 57 are all located in the accommodating space 5601. The axial direction of the guide rod 57 is perpendicular to the left-right direction Y. The axial direction of the guide rod 57 can be arranged perpendicular to the axial direction of the second rotating shaft 52. The second sliding member 542 is slidably sleeved on the guide rod 57.

[0063] The first sliding member 541 and the second sliding member 542 are arranged in sliding contact. A guide slide groove 5401 is provided on one of the first sliding member 541 and the second sliding member 542, and the other of the first sliding member 541 and the second sliding member 542 is penetrated in the guide slide groove 5401 and can slide in the guide slide groove 5401. Exemplarily, the second sliding member 542 may be provided with a guide slide groove 5401, and the first sliding member 541 is penetrated in the guide slide groove 5401. The guide slide groove 5401 is arranged in a long strip shape. The guide slide groove 5401 is extended along the rotation plane formed when the second rotating shaft 52 rotates relative to the chassis 100 along the height direction Z of the working equipment 1000. Among them, the rotation plane of the second rotating shaft 52 relative to the chassis 100 along the height direction Z of the working equipment 1000 can be perpendicular to the front-rear direction X of the working equipment 1000, and the guide slide groove 5401 can be extended along the height direction Z of the working equipment 1000. When the second rotating shaft 52 rotates relative to the chassis 100 along the height direction Z of the working equipment 1000, the second rotating shaft 52 drives the second swing arm 53 and the first sliding member 541 to rotate relative to the chassis 100, and the first sliding member 541 rotates relative to the second sliding member 542 in the guide groove 5401.

[0064] For example, in this embodiment, the first sliding member 541 can be configured as a columnar body, and the cross section of the first sliding member 541 can be configured as a circle to reduce the contact area between the side wall of the first sliding member 541 and the groove wall of the guide groove 5401, thereby reducing the sliding resistance when the first sliding member 541 slides. In some embodiments, the cross section of the first sliding member 541 can also be configured as a square, an ellipse, a regular polygon, etc. The central axis of the first sliding member 541 passes through the geometric center of the cross section of the first sliding member 541.

[0065] The second transmission member 23 is connected to the second sliding member 542. The second transmission member 23 is also used to push or pull the second sliding member 542 to slide along the guide rod 57, so that the second sliding member 542 pushes or pulls the first sliding member 541 to drive the second swing arm 53 to rotate around the central axis of the second rotating shaft 52, and the second swing arm 53 drives the second wheel shaft 51 to rotate around the second rotating shaft 52. The second transmission member 23 is hinged to the second sliding member 542.

[0066] A limiting hole 5602 is provided on the mounting base 56. The limiting hole is connected to the accommodation space 5601. The second transmission member 23 is inserted into the limiting hole. The limiting hole can limit the second transmission member 23, thereby reducing or avoiding the shaking of the second transmission member 23. The mounting base 56 includes two mounting members 561, which are arranged at intervals along the front-back direction X of the operating equipment 1000. The accommodation space 5601 is located between the two mounting members 561. The two mounting members 561 can be independently arranged, or the two mounting members 561 can be integrally formed. Along the left-right direction Y of the operating equipment 1000, the mounting base 56 is located between the two second swing arms 53. The second swing arm 53 is configured as a swing plate, and can also protect the first sliding member 541, the second sliding member 542, the second rotating shaft 52, and the rotating shaft 58 described below, which are located or partially located in the accommodation space 5601, thereby reducing or avoiding the problem of grass entanglement.

[0067] The number of guide rods 57 can be set to multiple. The central axes of the multiple guide rods 57 are parallel to each other and are arranged at intervals from each other. For example, the guide rods 57 can be set to four. The four guide rods 57 are distributed in an array. Through holes are provided on the four corners of the second sliding member 542, and the four guide rods 57 are correspondingly penetrated in the four through holes. The limiting hole 5602 can also make the connection between the second transmission member 23 and the second sliding member 542 located at the geometric center of the four guide rods 57, so that when the second transmission member 23 drives the second sliding member 542 to slide, the uniformity of the limiting force of the four guide rods 57 on the second sliding member 542 is improved, thereby reducing the sliding resistance between the second sliding member 542 and the guide rod 57, reducing the wear of the second sliding member 542 and the guide rod 57, and improving the service life. In some embodiments, the number of guide rods 57 can also be one, two, three, five, six, etc., and those skilled in the art can set it specifically according to actual needs, and it is not specifically limited in the embodiments of the present application.

[0068] The chassis lifting mechanism 500 also includes a rotating shaft 58. The rotating shaft 58 is used to connect with the chassis 100. The central axis of the rotating shaft 58 is perpendicular to the central axis of the second rotating shaft 52. The second rotating shaft 52 is connected to the rotating shaft 58. The second rotating shaft 52 is rotatable around the central axis of the rotating shaft 58. When the working equipment 1000 travels on an uneven ground, the second wheel 220 can adaptively drive the second rotating shaft 52 to rotate relative to the central axis of the rotating shaft 58 according to the ups and downs of the ground, so that the chassis 100 remains parallel or approximately parallel to the ground, which greatly reduces the bumps and vibrations of the working equipment 1000 when traveling on uneven ground, and improves the stability of the working equipment 1000 when traveling.

[0069] Exemplarily, the center axis of the rotating shaft 58 may be arranged parallel to the front-rear direction X of the working device 1000. When the second rotating shaft 52 rotates around the center axis of the rotating shaft 58, the rotating plane formed by the second rotating shaft 52 is parallel to the height direction Z of the working device 1000. In some embodiments, the center axis of the rotating shaft 58 may also be arranged at an angle to the front-rear direction X of the working device 1000. The center axis of the rotating shaft 58 is located in a plane parallel to the height direction Z and the front-rear direction X of the working device 1000, respectively. When the second rotating shaft 52 rotates around the center axis of the rotating shaft 58, the rotating plane formed by the second rotating shaft 52 is arranged at an acute angle to the height direction Z of the working device 1000.

[0070] In some embodiments, the rotating shaft 58 is rotatably arranged relative to the chassis 100 around the central axis of the rotating shaft 58. The rotating shaft 58 is rotatably connected to the mounting base 56. The mounting base 56 is provided with a mounting hole 5603. The rotating shaft 58 is inserted into the mounting hole 5603. Exemplarily, the chassis lifting mechanism 500 further includes a shaft sleeve 59. The shaft sleeve 59 is sleeved on the rotating shaft 58 and inserted into the mounting hole 5603 on the mounting base 56. The shaft sleeve 59 is used to reduce the wear of the rotating shaft 58 and the mounting base 56 when the rotating shaft 58 rotates relative to the mounting base 56, thereby increasing the service life.

[0071] In this embodiment, the rotating shaft 58 and the second rotating shaft 52 can be rotatably connected. In some embodiments, the rotating shaft 58 and the second rotating shaft 52 can be fixedly connected together by, but not limited to, bonding, screwing, clamping, welding, etc., or the rotating shaft 58 and the second rotating shaft 52 can be integrally formed. The second rotating shaft 52 is inserted through the rotating shaft 58; or the rotating shaft 58 is inserted through the second rotating shaft 52.

[0072] A through hole may be provided on the rotating shaft 58, and the second rotating shaft 52 is inserted into the through hole. In some embodiments, a bearing sleeve is provided at the connection between the second rotating shaft 52 and the rotating shaft 58. As a result, when the second rotating shaft 52 rotates relative to the rotating shaft 58, the wear between the second rotating shaft 52 and the rotating shaft 58 is reduced, and the service life is improved. The rotating shaft 58 can be rotatably arranged or fixedly arranged relative to the chassis 100. Among them, the rotating shaft 58 and the mounting base 56 can be fixedly connected together by, but not limited to, bonding, screwing, clamping, welding, etc., or the rotating shaft 58 and the mounting base 56 can also be integrally formed. In some embodiments, a through hole may be provided on the second rotating shaft 52, and the rotating shaft 58 is inserted into the through hole, the second rotating shaft 52 is fixedly arranged relative to the rotating shaft 58, and the rotating shaft 58 is rotatably arranged relative to the chassis 100.

[0073] For example, in this embodiment, the first transmission member 22 is configured as a bent rod structure, thereby improving the compression and tensile resistance of the first transmission member 22. The first transmission member 22 includes a first transmission part 221 and a second transmission part 222 connected to the first transmission part 221, and one end of the second transmission part 222 facing away from the first transmission part 221 is connected to the first lifting mechanism 10. The first transmission part 221 is arranged horizontally in the front-to-back direction X of the operating equipment 1000, and the second transmission part 222 is arranged obliquely in the front-to-back direction X of the operating equipment 1000.

[0074] Specifically, one end of the first transmission part 221 is connected to the driving member 21, and the other end of the first transmission part 221 is connected to the second transmission part 222. One end of the first transmission part 221 is hinged to the push rod 212, and the other end of the first transmission part 221 is connected to the second transmission part 222. One end of the second transmission part 222 facing away from the first transmission part 221 is hinged to the first swing arm 13, and the second transmission part 222 is tilted. The second transmission part 222 is tilted relative to the side of the first transmission part 221 facing the ground. As a result, the crank length of the connecting arm 14 is shortened, so that the telescopic stroke of the push rod 212 can be reduced, the compactness of the structure of the chassis lifting mechanism 500 is improved, and the swing frequency of the connecting arm 14 is increased to increase the rotation stroke of the first swing arm 13; and the risk of the connecting arm 14 rubbing against the chassis 100 when swinging around the first rotating axis 12 is avoided. It should be noted that the telescopic stroke of the push rod 212 refers to the maximum displacement of the push rod 212 during the telescopic process. The crank length of the connecting arm 14 refers to the distance between the connecting arm 14 and two hinge points of the first transmission member 22 and the first rotating shaft 12 .

[0075] For example, in this embodiment, the angle formed between the first transmission part 221 and the second transmission part 222 is an obtuse angle. The extension direction of the first transmission part 221 is parallel to the telescopic direction F of the push rod 212, thereby increasing the ground clearance of the first transmission part 221 and avoiding the first transmission part 221 from scratching against obstacles on the bottom or getting entangled with the grass pole. Of course, in some embodiments, the extension direction of the first transmission part 221 and the telescopic direction F of the push rod 212 can also be set at an angle.

[0076] In some embodiments, the first transmission member 22 is configured as a straight rod structure. The first transmission member 22 is arranged horizontally in the front-rear direction X of the operating equipment 1000. Specifically, the extension direction of the first transmission member 22 is parallel to the telescopic direction F of the push rod 212, so that the angle between the telescopic direction F of the push rod 212 and the transmission direction of the first transmission member 22 is almost zero, thereby improving the utilization rate of the driving force applied by the push rod 212 to the first transmission member 22, and reducing the vertical component force applied by the first transmission member 22 to the push rod 212, avoiding the problem of bending and damage of the push rod 212 under the action of the vertical component force, and extending the service life of the driving mechanism 20.

[0077] In some embodiments, the second transmission member 23 is configured as a bent rod structure. The second transmission member 23 may include a first transmission section 231, a second transmission section 232, and a third transmission section 233 connected in sequence. The first transmission section 231 is used to connect with the second sliding member 542. The third transmission section 233 is used to connect with the driving mechanism 20. The first transmission section 231 and the second transmission section 232, and the second transmission section 232 and the third transmission section 233 are respectively arranged at an angle. In some embodiments, the second transmission member 23 can also be arranged in an arc shape, a broken line shape, etc.

[0078] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
