The first motor 13, the second motor 933, and the lighting system 40 all function as electrical devices included in the riding mower 100, which convert electrical energy into other forms of energy.

As shown in fig. 1 and 3, the cutting system 10 is disposed on the lower side of the frame 91, so that the center of gravity of the entire riding mower 100 can be effectively lowered. The number of the mowing elements 12 is 2, the number of the first motors 13 is 2, and the two first motors 13 drive the mowing elements 12, respectively. Mowing element 12 is located within mowing space 121 surrounded by chassis 11. Mowing space 121 is open downward so that mowing element 12 can perform a cutting operation on vegetation located below mowing space 121.

As shown in fig. 1 and 5, the riding mower 100 further includes: a control module 95. The control module 95 can be disposed under the seat 92, which can save space and make the whole structure more compact. The control module 95 is used to control the electronic devices in each system. For the cutting system 10, the control module 95 can control the operation of the first motor 13.

As shown in fig. 6 to 11, the first motor 13 includes: a stator assembly 131, a rotor assembly 132, and a motor housing 133. The stator assembly 131 includes a stator coil 1311 and a stator core 1312, the rotor assembly 132 includes a rotor shaft 1321 rotatable about the rotation axis 1f, and the motor housing 133 surrounds a housing chamber 1331 formed to house the stator assembly 131 and at least a portion of the rotor assembly 132. Therein, the rotor shaft 1321 also passes through the accommodating chamber 1331 in the direction of the rotation axis 1f to protrude out of the motor housing 133. The motor housing 133 forms a containing cavity 1331 for sealing the stator assembly 131 and a part of the rotor assembly 132 inside, so that the problem that the first motor 13 fails due to the grass debris entering the containing cavity 1331 can be effectively avoided.

In the present embodiment, the chassis 11 is further formed with a first through hole 111 penetrating therethrough along the rotation axis 1f, and the first through hole 111 communicates the inside and the outside of the mowing space 121. The first motor 13 passes through the first through hole 111 in the direction of the rotation axis 1f so that the first motor 13 is located at least partially inside the mowing space 121. Thus, when the grass cutting element 12 is driven by the first motor 13 to rotate relative to the chassis 11, a heat dissipation airflow capable of dissipating heat of the portion of the first motor 13 located in the grass cutting space 121 is generated in the grass cutting space 121, and the heat dissipation airflow also has a grass discharging function. Since the first through hole 111 communicates the inside and the outside of the mowing space 121, when the mowing element 12 rotates, a heat dissipation airflow entering the mowing space 121 from the upper side of the chassis 11 through the first through hole 111 can be generated, and the heat dissipation airflow passes through the first motor 13 when passing through the first through hole 111, so that heat dissipation of the first motor 13 can be facilitated, and temperature rise of the first motor 13 during operation can be reduced.

More specifically, the chassis 11 includes a top wall 112 and a side wall 113, and the side wall 113 and the top wall 112 together surround the mowing space 121 described above. The top wall 112 of the chassis 11 is also recessed towards the grass cutting element 12 forming a recess 114, the first through hole 111 being provided at the bottom of the recess 114. Motor housing 133 passes through first through hole 111 such that motor housing 133 is partially inside mowing space 121 and partially outside mowing space 121. The first through hole 111 is disposed at the bottom of the groove 114, so that the height of the entire chassis 11 in the direction of the rotation axis 1f can be effectively reduced, and the size of the mowing space 121 formed by the chassis 11 can meet the requirement.

The motor housing 133 is also formed with a mounting portion 1332, and a portion of the groove bottom of the groove 114 surrounding the first through hole 111 constitutes a supporting portion 1141 for supporting the mounting portion 1332. The mounting portion 1332 is used to cooperate with the supporting portion 1141 to mount the motor housing 133 to the chassis 11, so that the first motor 13 is connected with the chassis 11. The dimension of the mounting portion 1332 in the radial direction perpendicular to the rotation axis 1f is also larger than the dimension of the first through hole 111 in this direction, so that the supporting portion 1141 surrounding the first through hole 111 can constitute a support for the mounting portion 1332, thereby enabling the first motor 13 to be stably mounted to the chassis 11.

The first motor 13 further includes a fastener 134 for connecting the mounting portion 1332 and the supporting portion 1141 such that the motor housing 133 is fixedly mounted to the chassis 11. When the mounting portion 1332 is connected to the supporting portion 1141, an air flow passage 135 communicating with the first through hole 111 is further formed between the mounting portion 1332 and the supporting portion 1141. When the grass cutting element 12 is driven to rotate by the first motor 13, the airflow passage 135 allows a heat dissipating airflow outside the grass cutting space 121 to flow through the airflow passage 135 and the first through hole 111 to enter the inside of the grass cutting space 121, the heat dissipating airflow being capable of dissipating heat from the first motor 13 when flowing through the first through hole 111.

3112 and 3113. The above-described hole into which the connection tube 32 is inserted is provided on the fixing portion 3124. The outer wall of the fixing portion 3124 is further formed with a guide rib 3125 for guiding the air flow to flow out from the grass basket body 311 to the outside, so that the air flow can flow out from a gap between the rotating portion 3123 and the fixing portion 3124, and the air flow can be prevented from swirling in the grass basket body 311 to form a swirling flow.

As shown in fig. 12, 15 to 18, the mounting assembly 33 includes: the grass basket comprises a support component 331, a first mounting seat group 332, a second mounting seat group 333 and a connecting rod component 334, wherein the support component 331 is used for supporting a grass basket body 311, the first mounting seat group 332 is fixedly connected to a first longitudinal beam 911, the second mounting seat group 333 is fixedly connected to a second longitudinal beam 912, the first mounting seat group 332 is further formed with a first mounting hole 3321, the second mounting seat group 333 is further formed with a second mounting hole 3331, and the connecting rod component 334 comprises a first connecting rod 3341 which is detachably inserted into the first mounting hole 3321 and a second connecting rod 3342 which is detachably inserted into the second mounting hole 3331. Wherein, the supporting component 331 is connected to the connecting rod component 334, and the first connecting rod 3341 and the second connecting rod 3342 constitute a detachable connection capable of being separated from each other. In this way, when the grass collecting system 30 is installed, the first connecting rod 3341 may be inserted into the first mounting hole 3321, then the second connecting rod 3342 may be inserted into the second mounting hole 3331, and finally the first connecting rod 3341 and the second connecting rod 3342 may be connected together by some mechanism, so that the grass collecting system 30 may be installed to the vehicle frame 91, and thus, the user may install the grass collecting system 30 to the vehicle frame 91 through a simple operation. The first connecting rod 3341 and the second connecting rod 3342 can be separated from each other, so that the whole grass collecting system 30 can be installed more easily, and the first connecting rod 3341 and the second connecting rod 3342 are prevented from being fixed into a whole so that the first connecting rod 3341 and the second connecting rod 3342 are difficult to be in position correspondence with the first installation hole 3321 and the second installation hole 3331 respectively when the grass collecting system 30 is installed; alternatively, even though the first and second connecting

rods

3341 and 3342 may be positioned to correspond to the first and second mounting

holes

3321 and 3331, respectively, it may reduce the stability of the connection between the grass collecting system 30 and the vehicle frame 91. The first connection rod 3341 and the second connection rod 3342 constitute a detachable connection which can be detached from each other, which means that the first connection rod 3341 is detached from the second connection rod 3342 without destroying the original structures of the first connection rod 3341 and the second connection rod 3342, for example, the first connection rod 3341 and the second connection rod 3342 constitute a snap connection, a screw connection, or a connection between the first connection rod 3341 and the second connection rod 3342 through an intermediate member, etc.

The support member 331 includes: a support base 3311 and a connecting plate 3312, the support base 3311 being used for supporting the basket body 311, the number of the support bases 3311 being 2, the two support bases 3311 being used for supporting the first basket portion 3112 and the second basket portion 3113, respectively. The connecting plate 3312 is fixedly connected to the supporting base 3311, and the connecting plate 3312 may be welded to the supporting base 3311, so that the structural strength of the supporting member 331 can be improved. The support member 331 is detachably connected to the connecting rod member 334, for example, in the embodiment, the support member 331 is connected to the connecting rod member 334 by a pin 3313. The support members 331 and the connecting rod member 334 are detachably connected, so that the grass collecting system 30 can be disassembled into a plurality of components for storage during transportation, thereby saving storage space. The rotating portion 3123 of the basket cover 312 is rotatably connected to the connection plate 3312 such that the basket body 311 is opened upward when the rotating portion 3123 is opened.

The support 3311 includes a support portion 3314 extending along a straight line 1m, and the basket body 311 is supported on the support portion 3314. The support portion 3314 can also guide the basket body 311 to be coupled to the support portion 3314 along the straight line 1 m. The direction of the straight line 1m obliquely intersects with the front-rear direction of the riding mower 100 to form an angle greater than 0 degree and equal to or less than 20 degrees, that is, the direction of the straight line 1m obliquely intersects with the longitudinal straight line 1d to form an angle greater than 0 degree and equal to or less than 20 degrees. Thus, when the basket body 311 is filled with grass, the weight of the grass basket assembly 31 is increased to press the support portion 3314 downward, and at this time, the support portion 3314 is inclined upward, and thus the support portion 3314 does not cause the basket body 311 to fall even if it is pressed downward. That is, the inclined disposition of the support portion 3314 serves to buffer the fall of the grass basket assembly 31.

The connecting rod assembly 334 further includes: an intermediate rod 3343, the intermediate rod 3343 being disposed between the first connecting rod 3341 and the second connecting rod 3342 to connect the first connecting rod 3341 and the second connecting rod 3342. In this way, the first and second connecting

rods

3341 and 3342 can be respectively installed to the first and

second installation holes

3321 and 3331 and then connected to each other by the intermediate rod 3343, thereby achieving the fixed connection of the first and second connecting

rods

3341 and 3342 and also enabling the connecting rod assembly 334 to be stably installed to the vehicle frame 91. The first connecting rod 3341 extends along a straight line, and the second connecting rod 3342 also extends along a direction parallel to the extending direction of the first connecting rod 3341, in this embodiment, the first connecting rod 3341 and the second connecting rod 3342 both extend along a vertical straight line 1n, the vertical straight line 1n is perpendicular to the longitudinal straight line 1d, and the vertical straight line 1n is also perpendicular to the transverse straight line 1 e. The intermediate rod 3343 is U-shaped, and the intermediate rod 3343 includes: a left connecting part 3344, a right connecting part 3345 and a middle part 3346, wherein the left connecting part 3344 is connected to the first connecting rod 3341, the right connecting part 3345 is connected to the second connecting rod 3342, and the middle part connects the left connecting part 3344 and the right connecting part 3345. The left connecting portion 3344 is connected to the first connecting rod 3341 by the first screw group 335 so that the intermediate rod 3343 is detachably connected to the first connecting rod 3341. The right connecting portion 3345 is connected to the second connecting rod 3342 by the second screw set 336 so that the intermediate rod 3343 is detachably connected to the second connecting rod 3342. In this way, the intermediate rod 3343 can serve the purpose of connecting the first connecting rod 3341 and the second connecting rod 3342, so that the first connecting rod 3341 and the second connecting rod 3342 are relatively fixed in the direction of the transverse straight line 1e, on the other hand, the intermediate rod 3343 can also serve the function of reinforcing the mounting assembly 33, thereby avoiding the problem of insufficient strength of the first connecting rod 3341 and the second connecting rod 3342.

The first mount group 332 includes: a first mounting post 3322 and a first extension 3323, and the second set 333 of mounting blocks includes a second mounting post 3332 and a second extension 3333.

The left housing component 21 is fixedly connected to the first extending seat 3323, and the right housing component 22 is fixedly connected to the second extending seat 3333. In this way, the strength of the set of the first and second mounting

seats

332 and 22 can be improved, and the problem of inconvenient installation and unstable structure caused by the direct installation of the left and

right housing assemblies

21 and 22 onto the first and second

longitudinal beams

911 and 912 is also avoided. The first mounting seat and the first extension seat 3323 are welded together, and the second mounting seat and the second extension seat 3333 are welded together. The first set of mounts 332 is connected to the first side member 911 by screws, and the second set of mounts 333 is connected to the second side member 912 by screws. As such, the first mount set 332 is required to bear the weight of the left housing assembly 21 on the left side of the seat 92 and the grass collection system 30 on the rear side of the seat 92, such that the stress distribution experienced by the first mount set 332 is relatively uniform, thereby increasing the service life of the riding mower 100. Likewise, the second set of mounts 333 are required to carry the weight of the right housing assembly 22 on the right side of the seat 92 and the grass collection system 30 on the rear side of the seat 92 so that the stress distribution experienced by the second set of mounts 333 is relatively uniform, thereby increasing the useful life of the riding mower 100.

In this way, when the mounting assembly 33 is mounted to the vehicle frame 91, the first connecting rod 3341 may be first inserted into the first mounting hole 3321, the second connecting rod 3342 may be inserted into the second mounting hole 3331, the intermediate rod 3343 may be then connected to the first connecting rod 3341 and the second connecting rod 3342, and the support assembly 331 may be finally connected to the connecting rod assembly 334, thereby enabling the grass-collecting system 30 to be mounted to the vehicle frame 91 through a simple operation.

In the present embodiment, the first and second mounting seat sets 332, 333 are simple in structure, the first mounting seat forms the first mounting hole 3321, the second mounting seat forms the second mounting hole 3331, and the first and second mounting

holes

3321, 3331 allow the grass collecting system 30 to be mounted to the vehicle frame 91. The first and second mounting

base groups

332, 333 are highly versatile and can be applied to the sunshade 35 shown in fig. 19. The sunshade 35 includes a sunshade assembly 351 and a mounting assembly 352 for mounting the sunshade assembly 351 to the riding lawn mower 100. Sunshade assembly 351 includes: sunshade 3511.

The supporting seat 3521 is connected with the connecting rod assembly, and the first connecting rod 3522 and the second connecting rod 3523 form a detachable connection which can be separated from each other. Specifically, the intermediate rod 3524 is detachably connected to the first connecting rod 3522 and the second connecting rod 3523, respectively.

As shown in fig. 1 and 20, the riding lawn mower 100 further includes an elevation system 70 for adjusting the height of the cutting system 10 relative to the frame 91. As shown in fig. 20 and 21, the height adjustment system 70 includes: the gear assembly 71 comprises an adjusting part 711 and a limiting part 712, the adjusting part 711 is used for being operated by a user, the limiting part 712 is used for limiting the adjusting part 711 to a preset gear, and the linkage assembly 72 is connected with the gear assembly 71 and the chassis 11. When the user operates the adjusting member 711, the adjusting member 711 can move to different preset positions relative to the limiting member 712, and the linkage assembly 72 drives the chassis 11 to change in height under the driving of the adjusting member 711, so that the riding mower 100 has different cutting heights.

As shown in fig. 20 to 23, the adjusting member 711 includes: an adjusting handle 7111, a gear position portion 7112 and a bent portion 7113. The adjusting handle 7111 is used for a user to operate, the gear portion 7112 is matched with the limiting member 712 so that the gear portion 7112 stays at a preset gear, and the bent portion 7113 is connected with the adjusting handle 7111 and the gear portion 7112. Here, the bent portion 7113 is bent from the shift position portion 7112 toward the main body 100a so that the adjustment handle 7111 is closer to the main body 100a in the left-right direction than the shift position portion 7112. Here, the bent portion 7113 is bent from the shift position portion 7112 toward the vehicle frame 91 so that the adjustment handle 7111 is closer to the vehicle frame 91 in the left-right direction with respect to the shift position portion 7112. The adjustment handle 7111 is provided on the right side of the vehicle frame 91 because the bent portion 7113 is bent toward the vehicle frame 91 in the left-right direction, so that the adjustment handle 7111 is closer to the vehicle frame 91 than it would be without the bent portion 7113. As is known, the chassis 11 is connected to the grass collecting system 30 by a connecting pipe 32, and a flip 115 is further connected to the chassis 11, the flip 115 having a first position and a second position. When the flip cover 115 is in the first position, the riding mower 100 is in the grass discharge mode, and grass clippings cut by the cutting system 10 can be discharged to the right of the riding mower 100 through the flip cover 115. When the lid 115 is in the second position, the chassis 11 may be connected to the grass collecting system 30 through the connection pipe 32 while the riding mower 100 is in the grass collecting mode, so that grass clippings cut by the cutting system 10 may be discharged to the grass basket body 311 through the lid 115. In the present embodiment, the adjusting handle 7111 is disposed at a small distance from the second longitudinal beam 912, so that the adjusting handle 7111 does not interfere with the movement of the flip 115 when the flip 115 is turned from the first position to the second position. In other words, the size of the adjustment handle 7111 can be increased as much as possible while satisfying the condition that the adjustment handle 7111 does not interfere with the movement of the folder 115, so that the comfort of the user operating the adjustment handle 7111 is not reduced. That is, if the bent portion 7113 is not provided on the adjusting member 711, the adjusting handle 7111 will be far away from the frame 91 in the left-right direction, and the adjusting handle 7111 will interfere with the movement of the flip cover 115, or the size of the adjusting handle 7111 is reduced, which may affect the comfort of the user holding the adjusting handle 7111. The lateral straight line 1e is parallel to the left-right direction of the riding mower 100, and the distance L7 between the adjustment handle 7111 and the second side member 912 in the lateral straight line 1e direction is smaller than the distance L8 between the shift position portion 7112 and the second side member 912 in the lateral straight line 1e direction, so that the distance between the adjustment handle 7111 and the second side member 912 can be made closer.

Specifically, the limiting member 712 forms a limiting hole 7121, and a plurality of limiting structures 7122 are formed on the wall of the limiting hole 7121. The shift portion 7112 passes through the limiting hole 7121, the shift portion 7112 includes an extending portion 7114 extending along a straight line 1p, the straight line 1p is perpendicular to the horizontal straight line 1e1p, a shift structure 7115 is formed on the extending portion 7114 in a protruding manner, and when the shift structure 7115 is matched with different limiting structures 7122, the chassis 11 stays at different heights. The bent portion 7113 has a first end 7116 and a second end 7117, the first end 7115 is connected to the shift portion 7112, and the second end 7117 is connected to the adjustment handle 7111. In the direction of the transverse straight line 1e, the second longitudinal beam 912 is disposed closer to the adjustment handle 7111 than the first longitudinal beam 911. The distance between the second end and the second stringer 912 is less than the distance between the first end 7116 and the second stringer 912 in the direction of the transverse line 1 e. That is, the bending of the bent portion 7113 toward the vehicle frame 91 does not limit the bending direction of the bent portion 7113, but rather, the bent portion 7113 may be bent toward the vehicle frame 91 such that the bent portion 7113 has a bending component toward the second side member 912 in the left-right direction, which may make the adjustment handle 7111 closer to the vehicle frame 91 in the left-right direction than the shift position portion 7112. The bent portion 7113 and the shift position portion 7112 are integrally formed, and a dimension L9 of the bent portion 7113 in the left-right direction is smaller than a maximum dimension L10 of the limiting hole 7121 in the left-right direction, so that the problem that the whole of the shift position portion 7112 and the bent portion 7113 cannot pass through the limiting hole 7121 due to the fact that the size of the bent portion 7113 is too large can be avoided. More specifically, a dimension L9 of the bent portion 7113 in the direction of the transverse straight line 1e is 20 mm or more and 40 mm or less.

In the present embodiment, the minimum distance L7 between the adjustment handle 7111 and the second longitudinal beam 912 in the direction of the transverse straight line 1e is 100 mm or less. The length of the adjustment handle 7111 in the direction of the transverse straight line 1e is greater than or equal to 80 mm and less than or equal to 150 mm, such that the size of the adjustment handle 7111 is substantially the same as the width of the palm of the user's hand, or the size of the adjustment handle 7111 is greater than the width of the palm of the user's hand, for example, to facilitate the user's grip.

The adjustment handle 7111 is connected to the bent portion 7113, and the adjustment handle 7111 extends from the bent portion 7113 in the left-right direction toward a direction away from the second longitudinal beam 912. That is, the free end of the adjustment handle 7111 is away from the second longitudinal beam 912 for convenient operation by the user, and the extension direction of the adjustment handle 7111 is parallel to the transverse straight line 1e for convenient holding by the user.

Linkage assembly 72 includes a drive member 721 connected to top wall 112 of chassis 11. The height adjustment system 70 further includes: the first fixing member 722 is fixedly connected with the first beam 913, the second fixing member 723 is fixedly connected with the side wall 113 of the chassis 11, and the connecting assembly 724 is connected with the first fixing member 722 and the second fixing member 723. In this way, the connection point of the connection assembly 724 to the chassis 11 is located below the highest point of the top wall 112 of the chassis 11, thereby improving the stability of the connection of the height adjustment system 70 to the chassis 11. More specifically, the second fixing member 723 is also provided on the side wall 113 on the front side of the chassis 11.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention.
