Description

Technical Field

[0001] This application specifically relates to a snowplow, and more specifically to a control method for the snow-throwing system of the snowplow. Background Technology

[0002] Snowplows are common power tools used to remove snow from the ground, with functions of sweeping and throwing snow. When using a snowplow to clear snow, users need to adjust the throwing angle according to the actual situation. After the snowplow is powered off, the angles of the operating parts, the throwing parts, or the guide vanes may become inconsistent. When the snowplow is powered on, the controller automatically controls the left and right rotation of the throwing parts or the up and down rotation of the guide vanes to correct the angle, which has a low safety factor.

[0047] Figure 1 A schematic diagram of a push-type machine tool 1 as a specific embodiment is shown. The push-type machine tool 1 includes a main body 100 and an operating component 200 connected to the main body 100. The operating component 200 includes an upper connecting rod, and the main body 100 includes a lower connecting rod. The upper and lower connecting rods are connected by fasteners such as screws and nuts to connect the main body 100 and the operating component 200. The upper and lower connecting rods form a telescopic connection to adjust the height of the operating component 200 relative to the ground. The operating component 200 also includes a handle assembly 21 for user operation. The user can push the handle assembly 21 to move the main body 100 relative to the ground, thereby moving the push-type machine tool 1 relative to the ground. The main body 100 includes a main housing 10, an energy system, a walking system 30, a snow sweeping system 40, and a snow throwing system 50. The energy system includes a battery pack 20, which can be a single battery pack or multiple battery packs. In this embodiment, the energy system includes a dual battery pack and consists of DC lithium batteries. For ease of explanation, based on the travel direction of the hand-push machine 1 under normal working conditions, the following settings are provided: Figure 1 The front-back and up-down directions are shown.

[0048] See Figures 1 to 4 As shown, the walking system 30 includes a walking wheel set, a self-propelled motor 32, and a transmission mechanism 33. The walking wheel set includes wheels 311 capable of walking on the ground. The wheels 311 rotate relative to the main body 100 around a first straight line 101, causing the hand-push working machine 1 to move relative to the ground. Specifically, the wheels 311 include a first wheel and a second wheel symmetrically distributed on both sides of the main body 100, and the first wheel and the second wheel are connected by a walking wheel axle 312.

[0049] The self-propelled motor 32 drives the wheels 311 to rotate relative to the main body 100 around the first straight line 101, causing the hand-push machine 1 to move relative to the ground. The self-propelled motor 32 includes a motor shaft, which drives the wheels 311 to rotate. In this embodiment, the self-propelled motor 32 is an electric motor, and the motor shaft is a motor shaft. The self-propelled motor 32 can also be called a self-propelled motor. As an optional implementation, the self-propelled motor can also be an internal combustion engine powered by fuel combustion.

[0050] The transmission mechanism 33 is used to transmit power between the self-propelled motor 32 and the walking wheel set so that when the motor shaft rotates actively, it can drive the wheels 311 to rotate. The transmission mechanism 33 includes a gearbox 331 and a drive shaft 332 connected to the gearbox 331. The gearbox 331 is connected to the motor shaft of the self-propelled motor 32 and is used to transmit the power of the self-propelled motor 32 to the drive shaft 332.

[0051] The transmission mechanism 33 also includes a first transmission gear 333 and a fixing member 334. The fixing member 334 is connected to the transmission shaft 332 and rotates synchronously with it. Specifically, when the self-propelled motor 32 is in operation, or when the motor shaft rotates actively, the motor shaft drives the transmission shaft 332 to rotate, the transmission shaft 332 drives the fixing member 334 to rotate, the fixing member 334 drives the first transmission gear 333 to rotate, and the first transmission gear 333 drives the wheel 311 to rotate. The structure and working principle of how the first transmission gear 333 drives the wheel 311 to rotate will be explained in detail below.

[0052] The transmission mechanism 33 also includes a first clutch 335 and a second transmission gear 336. Specifically, the first clutch 335 includes a movable element 3351, a drive paddle 3352, and an outer ring element 3353. When the wheel 311 rotates, the second transmission gear 336 meshes with the first gear 3111 of the wheel 311, and the first gear 3111 can drive the second transmission gear 336 to rotate. Since the rotation directions of the first transmission gear 333 and the second transmission gear 336 are opposite, the second transmission gear 336 applies a force to the drive paddle 3352 that is opposite to the rotation direction of the first transmission gear 333. Specifically, the second transmission gear 336 includes a first connecting portion 3361, and the drive paddle 3352 includes a second connecting portion 3352a. The first connecting portion 3361 can mesh with the second connecting portion 3352a, causing the second transmission gear 336 and the drive paddle 3352 to rotate in the same direction.

[0053] Drive lever 3352 is driven by wheel 311 to move movable member 3351 relative to drive shaft 332 between locked and unlocked positions. Outer ring member 3353 is sleeved on the outer periphery of drive shaft 332. Outer ring member 3353 has a mounting groove 3353a. Mounting groove 3353a accommodates fixed member 334 and movable member 3351. Fixed member 334 has a driving surface 3341. Specifically, movable member 3351 is a pin. Multiple pins are disposed within mounting groove 3353a. The number of driving surfaces 3341 is the same as the number of pins. Pins are located between the groove wall 3353b of mounting groove 3353a and the driving surface 3341. Optionally, the number of driving surfaces and pins can be multiple, thereby increasing the torque that can be transmitted by both, such as setting the number of driving surfaces and pins to 6 each. Figure 5a and Figure 5b The diagrams show the states of the movable component 3351 in the locked and unlocked positions, respectively. When the movable component 3351 is in the locked position, the drive shaft 332 can drive the wheel 311 to rotate. When the movable component 3351 is in the unlocked position, the wheel 311 can rotate freely relative to the drive shaft 332. That is, when the wheel 311 rotates clockwise or counterclockwise, the wheel 311 will not drive the drive shaft 332 to rotate.

[0054] The transmission mechanism 33 also includes a first elastic element 3362. The first elastic element 3362 is used to apply a force to the second transmission gear 336, so that the first connecting part 3361 of the second transmission gear 336 and the second connecting part 3352a of the drive paddle 3352 are tightly meshed, thereby realizing the transmission between the second transmission gear 336 and the drive paddle 3352, and improving the reliability of the transmission mechanism 33, making the transmission performance between the second transmission gear 336 and the drive paddle 3352 more stable.

[0055] When the self-propelled motor 32 is in working condition, that is, the motor shaft drives the transmission shaft 332 to rotate, and the transmission shaft 332 drives the fixed member 334 along the path of the motor. Figure 5a The rotation is clockwise as indicated by the arrow. The movable part 3351 simultaneously contacts the groove wall 3353b of the mounting groove 3353a and the driving surface 3341, thereby causing the transmission shaft 332 to drive the outer ring 3353 to rotate clockwise. The first transmission gear 333 is sleeved on the outside of the outer ring 3353. The first transmission gear 333 and the outer ring 3353 are connected via a flat-position transmission. The clockwise rotation of the outer ring 3353 drives the first transmission gear 333 to rotate clockwise. The first transmission gear 333 drives the wheel 311 to rotate. When the wheel 311 rotates, the drive lever 3352 receives a force from the wheel 311 in the opposite direction to the rotation of the first transmission gear 333, i.e., the drive lever 3352 receives a counterclockwise force. Driven by the wheel 311, the drive lever 3352 rotates to... Figure 5a In the position shown, the drive lever 3352 blocks the movement of the movable member 3351, preventing the movable member 3351 from moving from the locked position to the unlocked position, or in other words, keeping the movable member 3351 in the locked position.

[0056] After the self-propelled motor 32 stops driving, when the user pushes the hand-operated machine 1 forward, the wheel 311 rotates actively. At this time, the wheel 311 drives the second transmission gear 336 to rotate clockwise via the first gear 3311. The second transmission gear 336 drives the outer ring 3353 to rotate clockwise. The clockwise rotation of the outer ring 3353 relative to the transmission shaft 332 causes the movable part 3351 to disengage from the locked position, such as... Figure 5bAs shown. At this time, the moving part 3351 cannot simultaneously contact the groove wall 3353b of the mounting groove 3353a and the driving surface 3341 of the fixed part 334. At this time, the outer ring part 3353 can rotate relative to the drive shaft 332. That is, the wheel 311 can rotate relative to the drive shaft 332. Specifically, when the user pushes the hand-operated machine 1 to rotate the wheel 311 in any direction by a certain angle while the self-propelled motor 32 is off, the first clutch 335 enters the unlocked state. It can be understood that the user can unlock the first clutch 335 by pushing the hand-operated machine 1 forward or backward to rotate the wheel 311 clockwise or counterclockwise. The self-propelled motor 32 is in the off state, that is, the self-propelled motor 32 does not drive the wheel 311 to rotate.

[0057] See Figure 2 as well as Figures 6 to 8 As shown, the transmission mechanism 33 also includes a second clutch 337, an output shaft 338, and a drive device 339. The second clutch 337 is driven by a first transmission gear 333 and transmits the power from the motor shaft to the first transmission gear 333 to the output shaft 338, driving the output shaft 338 to rotate around a first straight line 101. The output shaft 338 is connected to a wheel 311 and drives the wheel 311 to rotate around the first straight line 101. The second clutch 337 has a first state and a second state. When the second clutch 337 is in the first state, the power from the motor shaft to the second transmission gear 336 can be transmitted to the output shaft 338 through the second clutch 337. When the second clutch 337 is in the second state, the power from the motor shaft to the second transmission gear 336 cannot be transmitted to the output shaft 338. This can be understood as follows: when the second clutch 337 is in the second state, the motor shaft rotates normally, but the second clutch 337 is disengaged from the output shaft 338, allowing the wheel 311 to rotate freely relative to the motor shaft. The drive unit 339 is used to drive the second clutch 337 to switch between the first state and the second state.

[0058] The second clutch 337 includes a first gear 3371 and a second gear 3372. The first gear 3371 is driven by a first transmission gear 333, and the second gear 3372 is driven by the first gear 3371. Specifically, the first gear 3371 has a first internal tooth 3371a, and the second gear 3372 has a first external tooth 3372a. The first internal tooth 3371a and the first external tooth 3372a mesh to transmit power from the first gear 3371 to the second gear 3372.

[0059] The output shaft 338 is sleeved on the axle of the traveling wheel 312 and is used to drive the wheel 311 to rotate around the first straight line 101. Specifically, the output shaft 338 has a second external tooth 3381 and the second gear 3372 has a second internal tooth 3372b. The second external tooth 3381 and the second internal tooth 3372b mesh to transmit the power on the second gear 3372 to the output shaft 338 to drive the wheel 311 to rotate.

[0060] The drive unit 339 is connected to the second clutch 337 and is used to drive the second clutch 337 to switch between a first state and a second state. The handle assembly 21 includes a first operating element 212 controlled by the user, and the drive unit 339 is controlled by the first operating element 212. Specifically, when the first operating element 212 is in the first position, the drive unit 339 drives the second clutch 337 to the first state. In this embodiment, as... Figure 1 As shown, the first operating element 212 is configured as a trigger for user operation. When the user controls the first operating element 212 to the second position, the drive device 339 drives the second clutch 337 to switch from the first state to the second state. When the user controls the first operating element 212 to switch from the first position to the second position, the drive device 339 rotates around the first straight line 101, thereby driving the second gear 3372 of the second clutch 337 to move along the direction of the first straight line 101, so that the second clutch 337 switches from the first state to the second state.

[0061] Specifically, the drive device 339 includes a spiral sleeve 3391, a drive member 3393, and a steel ball 3392 disposed between the spiral sleeve 3391 and the drive member 3393. The spiral sleeve 3391 is sleeved on the travel wheel axle 312 and fixedly connected to it. Specifically, the spiral sleeve 3391 and the travel wheel axle 312 form a through hole 3391b, and a fastener 3391c passes through the through hole 3391b to fix the spiral sleeve 3391 to the travel wheel axle 312. A spiral groove 3391a is formed on the spiral sleeve 3391, and the steel ball 3392 is disposed in the spiral groove 3391a. A positioning hole 3393a is formed on the drive member 3393, and the steel ball 3392 is at least partially disposed in the positioning hole 3393a. The driving component 3393 also includes a limiting component 3393b, which is at least partially disposed in the positioning hole 3393a for limiting the steel ball 3392. A connecting rod 3393c is also formed or connected to the driving component 3393. A second elastic component 3394 is connected or formed on the connecting rod 3393c. The second elastic component 3394 is fixedly connected to the main body 100.

[0062] The drive unit 339 and the second clutch 337 are connected by a connector 3395. The connector 3395 is fixedly connected to the drive unit 3393 and is used to drive the second gear 3372 and the drive unit 3393 to move synchronously in the direction of the first straight line 101. Specifically, the connector 3395 is configured as a U-shaped buckle. One end of the U-shaped buckle is fixed to the drive unit 3393, and the other end of the U-shaped buckle is in clearance fit with the first end face 3372c of the second gear 3372. When the second gear 3372 of the second clutch 337 rotates around the first straight line 101 under the drive of the first gear 3371, the power of the second gear 3372 is not transmitted to the drive unit 3393 because of the clearance fit between the U-shaped buckle and the first end face 3372c of the second gear 3372. It can be understood that the movement of the second gear 3372 and the drive unit 3393 in the plane perpendicular to the first straight line 101 is unrelated.

[0063] During normal operation, the movable part 3351 of the hand-push machine 1 is in the locked position, the first operating part 212 is in the first position, the second clutch 337 is in the first state, the motor shaft drives the transmission shaft 332 to rotate, the transmission shaft 332 drives the first transmission gear 333 to rotate, the first transmission gear 333 drives the first gear 3371 to rotate, the first gear 3371 drives the second gear 3372 to rotate, and the second gear 3372 drives the output shaft 338 to rotate, thereby driving the wheel 311 to rotate.

[0064] When a user needs to turn while walking, they can control the first operating element 212 to switch from a first position to a second position. During the switching process, the second clutch 337 switches from a first state to a second state. Specifically, when the second clutch 337 is in the first state, the positional relationship between the first gear 3371 and the second gear 3372 is as follows: Figure 9a As shown, when the second clutch 337 is in the second state, the positional relationship between the first gear 3371 and the second gear 3372 is as follows: Figure 9b As shown. Specifically, during the process of switching the operating member 22 from the first position to the second position, the driving member 3393 moves along the direction shown by the linkage 3393c. Figure 8 The first direction of movement is shown. Since the steel ball 3392 can only move within the spiral groove 3391a of the spiral sleeve 3391, the driving member 3393, under the action of the steel ball 3392, simultaneously moves along... Figure 8 The second direction of movement is shown. When the drive member 3393 moves in the second direction, it will drive the second gear 3372 to move in the second direction, so that the first external tooth 3372a of the second gear 3372 gradually disengages from the first internal tooth 3371a of the first gear 3371, causing the second clutch 337 to be in the second state.

[0065] In this embodiment, both the first clutch 335 and the second clutch 337 have a driven state and an unlocked state. The driven state of the second clutch 337 is its first state; the unlocked state of the second clutch 337 is its second state. When both the first clutch 335 and the second clutch 337 are in the driven state, the motor shaft drives the wheel 311 to rotate, and the hand-push working machine 1 operates normally. When either the first clutch 335 or the second clutch 337 is in the unlocked state, the wheel 311 can rotate freely relative to the motor shaft, meaning the user can push the hand-push working machine 1 to steer. See also... Figure 10 As shown, when the user needs to turn at a large angle, the first clutch 335 can be set to the unlocked state and the second clutch 337 to the driven state, and the hand-push working machine 1 turns in the direction shown in path 1, at which time the turning radius is large. When the user needs to turn at a small angle, the second clutch 337 can be set to the unlocked state, and the hand-push working machine 1 turns in the direction shown in path 2, at which time the turning radius is small, which can effectively improve the working efficiency of the hand-push working machine 1.

[0066] In other embodiments, the connector between the drive unit and the second clutch can also be implemented using other structural forms. Specifically, the connector is disposed between the clutch and the drive unit. See also Figures 11 to 13 As shown, a connecting member 3495 is disposed between the second gear 3472 and the driving member 3493 to achieve synchronous movement of the second gear 3472 and the driving member 3493 in a second direction. Specifically, the connecting member 3495 is configured as a plurality of balls. The second gear 3472 has a first annular groove 3475, and the driving member 3493 has a second annular groove 3494 opposite to the first annular groove 3475. The first annular groove 3475 and the second annular groove 3494 form a receiving space. The plurality of balls can roll along the first annular groove 3475 or the second annular groove 3494 within the receiving space. When the first operating member 212 controls the driving member 3493 to rotate in the first direction, the second gear 3472 moves in the second direction under the drive of the connecting member 3495, thereby switching the clutch from the first state to the second state.

[0067] In some embodiments, the hand-operated machine 1 has a manually operated mode and a self-driven mode. When the hand-operated machine 1 is in the manually operated mode, the user can manually push the hand-operated machine 1 forward or backward. When the hand-operated machine 1 is in the self-driven mode, the user does not need to manually push the hand-operated machine, and the self-driven motor 14 can drive the hand-operated machine 1 to move. As an optional implementation, the hand-operated machine 1 is provided with a switch to switch between the manually operated mode and the self-driven mode.

[0068] In some embodiments, the hand-operated machine 1 has a self-driven forward mode and a self-driven backward mode. In the self-driven forward mode, the rotational speed of the wheel 311 is greater than that in the self-driven backward mode. As an optional implementation, the hand-operated machine 1 includes two start switches to activate the self-driven forward mode and the self-driven backward mode, respectively. As another optional implementation, the hand-operated machine 1 includes a toggle switch to switch between the self-driven forward mode and the self-driven backward mode. As yet another optional implementation, when the user pushes the handle assembly 21 forward, the hand-operated machine 1 enters the self-driven forward mode; when the user pushes the handle assembly 21 backward, the hand-operated machine 1 enters the self-driven backward mode.

[0069] The push-type work machine 1 in the above embodiment can be configured as a snow sweeper, or it can be configured as other push-type power tools, such as a lawnmower.

[0070] like Figure 1 , Figures 14 to 16 As shown, the push-type working machine 1 is specifically configured as a snowplow, and the snowplow system 40 of the snowplow includes a snowplow blade 41 and a snow-throwing blade 42. The snowplow blade 41 is a functional element of the snowplow, used to stir the snow on the ground. The main housing 10 includes a snowplow blade housing 11 and a snow-throwing blade housing 12. The snowplow blade housing 11 forms a first receiving space 111 that accommodates at least a portion of the snowplow blade 41, and the snowplow blade 41 is rotatable within the first receiving space 111 about a second straight line 102. The snow-throwing blade housing 12 forms a second receiving space 121 that accommodates at least a portion of the snow-throwing blade 42, and the snow-throwing blade 42 is rotatable within the snow-throwing blade housing 12 about a third straight line 103. The second straight line 102 is perpendicular to the third straight line 103. The first receiving space 111 and the second receiving space 121 are interconnected. The first receiving space 111 defines a snow inlet 112, and the second receiving space 121 defines a snow outlet 122. Under the action of the snowplow 41, snow enters the snowplow housing 11 through the snow inlet 112 and is discharged from the snow outlet 122 after further action by the snow thrower 42. Specifically, the first accommodating space 111 is larger than the second accommodating space 121, and along the forward direction of the snowplow, the first accommodating space 111 is located in front of the second accommodating space 121. The snowplow housing 11 and the snow thrower housing 12 are integrally formed or mechanically connected together to realize the communication between the first accommodating space 111 and the second accommodating space 121. The main housing 10 also includes a snow discharge tube 13 protruding from the second accommodating space 121, which extends tangentially along a cylindrical shape and connects to the snow outlet 122. The space formed by the snow discharge tube 123 communicates with the second accommodating space 121. In this embodiment, the snowplow housing 1, the snow thrower housing 12, and the snow discharge tube 13 are all stamped parts and are welded together as a whole.

[0071] The snow removal system 40 also includes a power motor 43, which drives the snowplow 41 to rotate about the second linear axis 102 and drives the snow-throwing paddle 42 to rotate about the third linear axis 103. Specifically, the output power of the power motor 43 is greater than or equal to 3000W and less than or equal to 6000W, and the output speed of the power motor 43 is greater than or equal to 5000 rpm and less than or equal to 15000 rpm. The speed of the snow-throwing paddle 42 is greater than or equal to 500 rpm and less than or equal to 1500 rpm, which ensures that the snowplow has excellent snow removal performance.

[0072] See Figure 1 As shown, the handle assembly 21 includes operating handles 211 for user operation, and two operating handles 211 are respectively disposed on the snow sweeper. Figure 10 The left and right sides are shown in the diagram. The center of gravity of the snowplow is set as G, approximately located in the middle of the snowplow along the front-to-back direction, and positioned between the first straight line 101 and the second straight line 102 in the front-to-back direction. In the front-to-back direction, the distance from the grip center of the operating handle 211 to the first straight line 101 is L1, and the distance from the first straight line 101 to the second straight line 102 is L2. The ratio of L1 to L2 is greater than or equal to 1 and less than or equal to 1.6. The battery pack 20 is at least partially located above the walking wheel axle 312 to balance the center of gravity G.

[0073] See Figure 1 as well as Figures 17 to 22 As shown, the snow-throwing system 50 of the snowplow includes a deflector 51 and a snow-throwing component 52. The snow-throwing component 52 forms a semi-enclosed channel with an opening. The first end of the snow-throwing component 52 is rotatably connected to the snow-throwing paddle housing 12 to connect the second receiving space 121 to the outside. That is, the snow-throwing component 52 connects the snow-throwing paddle housing 12 and the deflector 51, forming a continuous channel for snow discharge. The deflector 51 is installed at the second end of the snow-throwing component 52. In this embodiment, the deflector 51 is installed at the top of the snow-throwing component 52. Snow is thrown into the air after passing through the snow-throwing paddle housing 12, the snow discharge tube 13, the snow-throwing component 52, and the deflector 51.

[0074] The snow-throwing system 50 also includes a first drive device 54 and a second drive device 55. The first drive device 54 is connected to the upper or middle part of the snow-throwing component 52 and is used to drive the snow-throwing component 52 to rotate relative to the main body 100 about a first axis 104. The second drive device 55 is connected to a guide plate 51 and is used to drive the guide plate 51 to rotate relative to the snow-throwing component 52 about a second axis 105. The first axis 104 is perpendicular to the second axis 105.

[0075] Specifically, the first driving device 54 includes at least a first motor 541 and a first transmission mechanism 542. The first transmission mechanism 542 includes at least a third gear 5421, a fourth gear 5422, and a first output shaft 5423. The first motor 541 drives the third gear 5421 to rotate, the third gear 5421 drives the fourth gear 5422 to rotate, and the fourth gear 5422 drives the first output shaft 5423 to rotate around the first axis 104. Specifically, the third gear 5421 and the fourth gear 5422 are bevel gears. The first driving device 54 also includes a rotating member 543, one end of which is sleeved on the first output shaft 5423 and rotates with it. The other end of the rotating member 543 is fixedly connected to the snow-throwing member 52, for driving the snow-throwing member 52 to rotate around the first axis 104.

[0076] The second drive unit 55 includes a second motor 551 and a second transmission mechanism 552. The second transmission mechanism 552 includes at least a worm gear 5521, a first turbine 5522, and a second output shaft 5523. The second motor 551 drives the worm gear 5521 to rotate, and the worm gear 5521 drives the first turbine 5522 to rotate the second output shaft 5523 around the second axis 105. The second output shaft 5523 drives the guide vane 51 to rotate around the second axis 105.

[0077] When the snow-throwing component 52 is in the middle position, see Figure 22 As shown, both the first motor 541 and the second motor 551 are located within a first circular region 5411 centered on the second axis 105, and the radius of the first circular region 5411 is less than or equal to 800 mm. Further, the radius of the first circular region 5411 is less than or equal to 650 mm. Further, the radius of the first circular region 5411 is less than or equal to 550 mm. Further, the radius of the first circular region 5411 is less than or equal to 400 mm. Further, the radius of the first circular region 5411 is less than or equal to 300 mm. Wherein, "when the snow-throwing component 52 is in the middle position" means that the extension direction of the snow-throwing component 52 is in the front-to-back direction.

[0078] The distance from the center of gravity of the first motor 541 to the first axis 104 is greater than or equal to 40 mm and less than or equal to 100 mm. The second motor 551 is located within a second circular region centered on the second axis 105, and the radius of the second circular region is greater than or equal to 25 mm and less than or equal to 75 mm.

[0079] The snow-throwing system 50 also includes a support rod 53 extending in a vertical direction, at least for supporting the first drive device 54. A first end of the support rod 53 is fixed to the snow outlet tube 13 of the main housing 10, and a second end extends vertically. The first drive device 54 is fixedly mounted on the second end of the support rod 53. In some embodiments, the support rod 53 consists of a first rod portion and a second rod portion, which are locked together by a locking assembly and form a detachable connection, thereby allowing the snow-throwing system 50 to be detached from the main body 100 for convenient transportation and to save storage space.

[0080] The snow-throwing system 50 also includes a housing for accommodating the first drive unit 54 and the second drive unit 55. In this embodiment, the aforementioned housing is also referred to as the motor housing. The motor housing includes a first part 561 and a second part 562. The first part 561 is fixedly mounted to the guide plate 51 and can rotate relative to the second part 562 about a second axis 105. Specifically, the second part 562 forms a connecting portion 5621, and when the first part 561 rotates relative to the second part 562 about the second axis 105, the first part 561 is slidably connected to the connecting portion 5621. The motor housing also includes a third part, and the second part 562 can rotate relative to the third part about a first axis 104. The third part includes a first upper housing 5631 and a first lower housing 5632. One end of the support rod 53 is connected to the snow outlet tube 13, and the other end is used to support the third part of the motor housing. The snow-throwing system 50 also includes a circuit board assembly 573, which is disposed within the receiving space formed by the first upper housing 5631 and the first lower housing 5632. The snow-throwing system 50 also includes a top cover 5633 detachably connected to the first upper housing 5631 for sealing the circuit board assembly 573. In this way, when the circuit board assembly fails, the top cover 5633 can be opened directly to repair the circuit board assembly 573.

[0081] Specifically, the first upper housing 5631 and the first lower housing 5632 form a receiving space to accommodate at least a portion of the first driving device 54 and the second driving device 55. After the first upper housing 5631 and the first lower housing 5632 are assembled vertically, they are fastened with screws. The first part 561 is rotatably connected to the second part 562 and forms a receiving space with the guide plate 51 to accommodate at least a portion of the second driving device 55. When the first part 561 rotates relative to the second part 561 about the second axis 105, the connecting part 5621 does not disengage from the first part 561, ensuring that the second driving device 55 is always located within the aforementioned receiving space, thereby achieving a waterproof effect. The first part 561 is rotatably connected to the second part 562. When the guide plate 51 rotates about the second axis 105, it causes the first part 561 to rotate relative to the second part 562.

[0082] As another possible implementation, the first motor 541a and the second motor 551a are configured as follows: Figure 23 The arrangement is as shown. Unlike the previous embodiment, the second motor 551a is positioned below the first motor 541a. The second motor 551a drives the worm gear 5521a to rotate, the worm gear 5521a drives the first turbine 5522a to rotate, and the first turbine 5522a drives the reel 5523a to rotate the guide plate 51 around the second axis 105a. In this embodiment, when the snow-throwing component 52 is in the middle position, both the first motor 541a and the second motor 551a are located within the first circular region 5411a centered on the second axis 105a, and the radius of the first circular region 5411a is less than or equal to 800 mm. Further, the radius of the first circular region 5411a is less than or equal to 650 mm. Further, the radius of the first circular region 5411a is less than or equal to 550 mm. Further, the radius of the first circular region 5411a is less than or equal to 400 mm. Further, the radius of the first circular region 5411a is less than or equal to 300 mm. When the snow-throwing component 52 is in the middle position, it means that the extension direction of the snow-throwing component 52 is in the front-back direction.

[0083] The snow-throwing system 50 also includes a control device 57. See also Figure 24 As shown, the control device 57 is used to control the operating state of the first drive device 54 and the second drive device 55. The control device 57 includes an operating element disposed on the handle assembly 21, a first sensing device, a second sensing device, and a circuit board assembly 573. The aforementioned operating element can be understood as the second operating element 213. The circuit board assembly 573 is disposed above the first drive device 54 and is located within the receiving space formed by the first upper housing 561 and the first lower housing 562.

[0084] The second operating element 213 is operated by the user to adjust the angle of rotation of the snow-throwing component 52 around the first axis 104, and the angle of rotation of the guide plate 51 relative to the snow-throwing component 52 around the second axis 105. Specifically, the second operating element 213 is configured as a handle that the user can hold, allowing the user to rotate it in the forward-backward direction, or in the left-right direction, or simultaneously in both directions. For example, the user can control the second operating element 213 to rotate forward while simultaneously controlling it to rotate to the left. In this embodiment, when the user operates the second operating element 213 to rotate left or right, the snow-throwing component 52 rotates accordingly around the first axis 104. When the user operates the second operating element 213 to rotate forward or backward, the guide plate 51 rotates accordingly around the second axis 105. Of course, the second operating element 213 can also be implemented in other ways; the implementation form of the second operating element 213 is not limited here.

[0085] The first sensing device is used to detect the angles of the second operating member 213 and the snow-throwing member 52 in the left-right direction. In this embodiment, the first sensing device includes a first sensor 5711 and a second sensor 5712. Specifically, the first sensor 5711 is used to detect the angle of the second operating member 213 in the left-right direction, and the second sensor 5712 is used to detect the angle of the snow-throwing member 52 in the left-right direction. See also Figure 19 As shown, the second sensor 5712 is mounted to the first output shaft 5423.

[0086] The second sensing device is used to detect the angle of the second operating member 213 in the front-rear direction and the angle of the guide vane 51 in the vertical direction. In this embodiment, the second sensing device includes a third sensor 5721 and a fourth sensor 5722. Specifically, the third sensor 5721 is used to detect the angle of the second operating member 213 in the front-rear direction, and the fourth sensor 5722 is used to detect the angle of the guide vane 51 in the vertical direction. See also... Figure 18 As shown, the second transmission mechanism 552 also includes a second turbine 5524 and a third output shaft 5525. A fourth sensor 5722 is mounted on the third output shaft 5525.

[0087] In this application, the first sensor 5711, the second sensor 5712, the third sensor 5721, and the fourth sensor 5722 are configured as Hall effect sensors. It is understood that other types of sensors can also be used to obtain the corresponding angles. Of course, the first sensor 5711, the second sensor 5712, the third sensor 5721, and the fourth sensor 5722 can be of one type or multiple types. In short, this application does not limit the type or number of the first sensor 5711, the second sensor 5712, the third sensor 5721, and the fourth sensor 5722.

[0088] The circuit board assembly 573 includes at least a first controller 5731, a second controller 5732, a first drive circuit 5733 electrically connected to the first controller 5731, and a second drive circuit 5734 electrically connected to the second controller 5732. The first controller 5731 controls the first drive circuit 5733 to drive the first motor 541. The second controller 5732 controls the second drive circuit 5734 to drive the second motor 551. Specifically, the first drive circuit 5733 and the second drive circuit 5734 are configured as a three-phase bridge circuit. The first drive circuit 5733 includes three electronic switches configured as high-side switches and three electronic switches configured as low-side switches. Similarly, the second drive circuit 5734 also includes three electronic switches configured as high-side switches and three electronic switches configured as low-side switches. Since the specific circuitry of the drive circuits is common technology in the art, it will not be described in detail here.

[0089] The first controller 5731 is electrically connected to the first sensor 5711 and the second sensor 5712, and is used to acquire the angles of the second operating member 213 and the snow-throwing member 52 in the left and right directions, respectively. Specifically, the first controller 5731 acquires the first electrical signal output by the first sensor 5711 and the second electrical signal output by the second sensor 5712 in real time, and controls the on / off state of the first motor 541 based on the first and second electrical signals. Specifically, the first controller 5731 sets a preset second electrical signal based on the acquired first electrical signal, and compares the preset second electrical signal with the acquired second electrical signal. When the second electrical signal is different from the preset electrical signal, the first motor 541 is controlled to start, thereby driving the snow-throwing member 52 to rotate around the first axis 104, so that the angle of the snow-throwing member 52 in the left and right directions corresponds to the angle of the second operating member 213 in the left and right directions. After the first motor 541 starts, the first controller 5731 acquires the first and second electrical signals in real time until the acquired second electrical signal is the preset second electrical signal, and then controls the first motor 541 to turn off after a period of time.

[0090] Specifically, the second operating member 213 can rotate in the left-right direction within an angle range of approximately 0° to 80°, and the snow-throwing member 52 can rotate around the first axis 104 within an angle range of approximately 0° to 200°. The angle of the snow-throwing member 52 in the left-right direction corresponds to the angle of the second operating member 213 in the left-right direction. This can be understood as follows: when the current angle of the second operating member 213 is 0°, the angle of the snow-throwing member 52 is set to 0°; when the current angle of the second operating member 213 is 40°, the angle of the snow-throwing member 52 is set to 100°; when the current angle of the second operating member 213 is 80°, the angle of the snow-throwing member 52 is set to 200°; and when the current angle of the second operating member 213 is 20°, the angle of the snow-throwing member 52 is set to 50°.

[0091] Under certain operating conditions, during snow removal, the snow-throwing component 52 and the deflector 51 are subjected to the reaction force of the thrown snow. When the reaction force is large, it may drive the first transmission mechanism 542 or the second transmission mechanism 552 to rotate, thereby damaging the electronic components in the circuit board assembly 573. To alleviate the above problem, in this embodiment, after the first motor 541 or the second motor 551 is turned off, the three electronic switches controlling the low-side switch or the high-side switch of the first drive circuit 5733 are simultaneously turned on, and the three electronic switches controlling the low-side switch or the high-side switch of the second drive circuit 5734 are simultaneously turned on.

[0092] Next, we will combine Figure 25 The control method of the snow-throwing component 52 of the snow-throwing system 50 is described in detail below, with specific steps as follows:

[0093] S10: Acquire the first electrical signal output by the first sensor and the second electrical signal output by the second sensor.

[0094] S11: Obtain the preset second electrical signal.

[0095] S12: Determine whether the second electrical signal is equal to the preset second electrical signal. If yes, proceed to step S14; otherwise, proceed to step S13.

[0096] S13: Control the first motor to start, then return to step S10.

[0097] S14: Determine whether the first motor has started. If yes, proceed to step S15; otherwise, proceed to step S10.

[0098] S15: Shut down the first motor.

[0099] S16: The three electronic switches that control the high-side or low-side switch of the first drive circuit are turned on simultaneously.

[0100] The second controller 5732 is electrically connected to the third sensor 5721 and the fourth sensor 5722, and is used to acquire the angle of the second operating member 213 in the front-back direction and the angle of the guide plate 51 in the vertical direction, respectively. Specifically, the second controller 5732 acquires the third electrical signal output by the third sensor 5721 and the fourth electrical signal output by the fourth sensor 5722 in real time, and controls the opening state of the second motor 551 based on the third electrical signal and the fourth electrical signal. Specifically, the second controller 5732 sets a preset fourth electrical signal based on the acquired third electrical signal, and compares the preset fourth electrical signal with the acquired fourth electrical signal. When the fourth electrical signal is different from the preset electrical signal, it controls the second motor 551 to start, thereby driving the guide plate 51 to rotate around the second axis 105, so that the angle of the guide plate 51 in the vertical direction corresponds to the angle of the second operating member 213 in the front-back direction. After the second motor 551 starts, the second controller 5732 acquires the third and fourth electrical signals in real time until the acquired fourth electrical signal is the preset fourth electrical signal, and then controls the second motor 551 to turn off after a period of time.

[0101] Specifically, the second operating member 213 can rotate within a range of approximately 0° to 50° in the front-to-back direction, and the guide vane 51 can rotate within a range of approximately 0° to 65° around the second axis 105. The angle of the guide vane 51 in the vertical direction corresponds to the angle of the second operating member 213 in the front-to-back direction. This can be understood as follows: when the current angle of the second operating member 213 is 0°, the angle of the guide vane 51 is set to 0°; when the current angle of the second operating member 213 is 50°, the angle of the guide vane 51 is set to 65°; and when the current angle of the second operating member 213 is 10°, the angle of the guide vane 51 is set to 13°.

[0102] Next, we will combine Figure 26 The control method of the deflector 51 of the snow-throwing system 50 is described in detail below, with specific steps as follows:

[0103] S20: Acquire the third electrical signal output by the third sensor and the fourth electrical signal output by the fourth sensor.

[0104] S21: Obtain the preset fourth electrical signal.

[0105] S22: Determine whether the fourth electrical signal is equal to the preset fourth electrical signal. If yes, proceed to step S24; otherwise, proceed to step S23.

[0106] S23: Control the second motor to start, then return to step S20.

[0107] S24: Determine whether the second motor is started. If yes, proceed to step S25; otherwise, proceed to step S20.

[0108] S25: Turn off the second motor.

[0109] S26: The three electronic switches controlling the high-side or low-side switch of the second drive circuit are turned on simultaneously.

[0110] It should be noted that the control of the deflector 51 and the snow-throwing component 52 in this embodiment is independent of each other. This can be understood as the user controlling the second operating component 213 to rotate simultaneously in the forward / backward and left / right directions. At this time, the first controller 5731 controls the first drive circuit 5733 to drive the first motor 541, thereby controlling the snow-throwing component 52 to rotate around the first axis 104 by a corresponding angle. The second controller 5732 controls the second drive circuit 5734 to drive the second motor 551, thereby controlling the deflector 51 to rotate around the second axis 105 by a corresponding angle.

[0111] In this embodiment, the first controller 5731 controls the start of the first motor 541 based on the state of the second operating element 213. Specifically, the first controller 5731 controls the start of the first motor 541 based on the first electrical signal output by the first sensor 5711 and the second electrical signal output by the second sensor 5712 of the first sensing device 571. After the first motor 541 starts, the first controller 5731 controls the first motor 541 to run at a constant speed of a first rotational speed to drive the snow-throwing component 52 to rotate relative to the main body 100 around the first axis 104. The second controller 5732 controls the start of the second motor 551 based on the state of the second operating element 213. Specifically, the second controller 5732 controls the start of the second motor 551 based on the third electrical signal output by the third sensor 5721 and the fourth electrical signal output by the fourth sensor 5722 of the second sensing device 572. After the second motor 551 starts, the second controller 5732 controls the second motor 551 to run at a constant speed of a second rotational speed to drive the guide vane 51 to rotate relative to the snow-throwing component 52 around the second axis 105. The second rotational speed is greater than or equal to the first rotational speed. It is understandable that the first motor 541 or the second motor 551 operates at a constant speed during operation, and is independent of the rotation speed of the second operating element 213.

[0112] In some embodiments, after the snowplow is powered off, user error may cause the angle of the second operating component 213 in the front-to-back direction to mismatch with the angle of the guide vane 51 in the up-down direction, or the angle of the second operating component 213 in the left-to-right direction to mismatch with the angle of the snow-throwing component 52 in the left-to-right direction. When the user powers on the snowplow, the first controller 5731 will actively correct the angle of the snow-throwing component 52 to make it correspond to the angle of the second operating component 213 in the left-to-right direction. At the same time, the second controller 5732 will actively correct the angle of the guide vane 51 to correspond to the angle of the second operating component 213 in the front-to-back direction. To further improve the safety of the snowplow during use and prevent the snow-throwing component 52 and the guide vane 51 from contacting the user's body during rotation, thereby causing injury to the user.

[0113] In this embodiment, when the snowplow is powered on, the first controller 5731 and the second controller 5732 will not actively adjust the angle of the snow-throwing component 52 or the deflector 51, even if the current angle of the deflector 51 or the snow-throwing component 52 does not correspond to the angle of the second operating component 213. When the user operates the second operating component 213, the first controller 5731 or the second controller 5732 obtains the first trigger signal or the second trigger signal output by the second operating component 213 through the first sensing device 571 or the second sensing device 572, and then controls the corresponding motor to adjust the angle of the deflector 51 or the snow-throwing component 52 so that they correspond to the current angle of the second operating component 213. It should be understood that the above-mentioned "after the snowplow is powered on" should refer to the first controller 5731 or the second controller 5732 being powered on.

[0114] As one possible implementation, after the snowplow is powered on, the user can individually adjust the angles of the deflector 51 and the snow-throwing component 52, according to their own choice. Optionally, the user can adjust the angle of the deflector 51 first, and then adjust the angle of the snow-throwing component 52. Alternatively, the user can adjust the angle of the snow-throwing component 52 first, and then adjust the angle of the deflector 51.

[0115] When the user selects to correct the angle of the snow-throwing component 52, the user operates the second operating component 213 to rotate it left or right by a first preset angle. At this time, the first controller 5731 obtains the first trigger signal output by the second operating component 213 through the first sensing device 571. After obtaining the first trigger signal, the first controller 5731 obtains the first angle of the second operating component 213 in the left-right direction and the second angle of the snow-throwing component 52 in the left-right direction through the first sensing device 571, and controls the activation state of the first motor 541 based on the first and second angles. The value range of the first preset angle is set to 5° to 10°. Specifically, when the second angle corresponds to the first angle, the first controller 5731 controls the first motor 541 not to start; when the second angle does not correspond to the first angle, the first controller 5731 controls the first motor 541 to start, driving the snow-throwing component 52 to rotate around the first axis 104, so that the current angle of the snow-throwing component 52 corresponds to the first angle of the second operating component 213.

[0116] When the user selects to calibrate the guide vane 51, the user operates the second operating element 213 to rotate it forward or backward by a second preset angle. At this time, the second controller 5732 obtains the second trigger signal output by the second operating element 213 through the second sensing device 572. After obtaining the second trigger signal, the second controller 5732 obtains the third angle of the second operating element 213 in the forward / backward direction and the fourth angle of the guide vane 51 in the up / down direction through the second sensing device 572, and controls the activation state of the second motor 551 based on the third and fourth angles. The value range of the second preset angle is set to 5° to 10°. Specifically, when the third angle corresponds to the fourth angle, the second controller 5732 controls the second motor 551 not to start; when the third angle does not correspond to the fourth angle, the second controller 5732 controls the second motor 551 to start, driving the guide vane 51 to rotate around the second axis 105, so that the current angle of the guide vane 51 corresponds to the third angle of the second operating element 213.

[0117] It should be noted that the correspondence between the second operating component 213 and the snow-throwing component 52 in the left-right direction and the correspondence between the second operating component 213 and the guide vane 51 in the up-down direction have been described in detail above, and will not be repeated here.

[0118] In another possible implementation, the user operates the second operating element 213 to simultaneously output a first trigger signal and a second trigger signal. After the first controller 5731 acquires the first trigger signal, it corrects the angle of the snow-throwing element 52. After the second controller 5732 acquires the second trigger signal, it corrects the angle of the guide vane 51. Specifically, the simultaneous output of the first and second trigger signals by the second operating element 213 means that the user operates the second operating element 213 to rotate it simultaneously in both the forward / backward and left / right directions.

[0119] In other embodiments, the operating component 200 further includes a triggering device for outputting a trigger signal. Unlike the embodiments described above, where the trigger signal is output by the second operating element, in this embodiment, the trigger signal is output by the triggering device. The triggering device can optionally be a button, switch, or other form. The triggering device can optionally be mounted on or near the second operating element. Of course, the triggering device can also be mounted in other locations. This application does not limit the form or location of the triggering device.

[0120] After the snowplow is powered on, the user needs to operate the trigger device to output a trigger signal. Upon receiving the trigger signal, the control unit controls the first and second motors to start based on the actual conditions of the deflector and snow-throwing components. The actual conditions of the deflector and snow-throwing components refer to whether the angle of the current deflector corresponds to the angle of the second operating component in the front-back direction, and whether the angle of the current snow-throwing component corresponds to the angle of the second operating component in the left-right direction.

[0121] Specifically, the control unit can acquire the trigger signal in different ways. In some embodiments, the control unit includes a first controller and a second controller. The first controller can acquire a first angle of the second operating element and a second angle of the snow-throwing element via a first sensing device. The second controller can acquire a third angle of the second operating element and a fourth angle of the deflector via a second sensing device. The trigger device is electrically connected to both the first and second controllers. When the user presses the trigger device, both the first and second controllers simultaneously receive the trigger signal output by the trigger device and activate the corresponding first or second motor based on the current status of the deflector and snow-throwing element.

[0122] In other embodiments, the control unit includes a first controller, a second controller, and a third controller. The first controller can acquire a first angle of the second operating element and a second angle of the snow-throwing element via a first sensing device. The second controller can acquire a third angle of the second operating element and a fourth angle of the deflector via a second sensing device. The third controller is connected to a triggering device to acquire a trigger signal output by the triggering device. Specifically, the third controller is electrically connected to both the first and second controllers. When the third controller acquires the trigger signal, the first controller controls the first motor to operate based on the first and second angles so that the second angle corresponds to the first angle. Simultaneously, the second controller controls the second motor to operate based on the third and fourth angles so that the fourth angle corresponds to the third angle.

[0123] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
