Description

Technical Field

[0001] This application relates to the field of lawnmower technology, and more particularly to a cutting assembly and cutting device. Background Technology

[0002] A lawnmower robot is a mobile robot used to trim lawns, gardens and other outdoor greenery. The lawnmower robot is equipped with a cutting device, and the cutting component is a key component of the cutting device. During the cutting process, the cutting component will rotate at high speed to cut the target material such as lawn and vegetation.

[0003] Currently, disassembling the cutting components in cutting devices is generally quite troublesome. When the cutting components need to be replaced or repaired, disassembling them is cumbersome, time-consuming, and inefficient. Summary of the Invention

[0004] The purpose of this application is to provide a cutting component and a cutting device, which aims to solve the technical problems that the disassembly of the cutting component is troublesome, time-consuming, and inefficient.

[0005] To achieve the above objectives, the solution provided in this application is as follows:

[0006] In a first aspect, this application provides a cutting assembly, which is detachably mounted on a connector of a cutting device, wherein the cutting assembly includes:

[0007] Turntable;

[0008] A movable mechanism is slidably mounted on the turntable;

[0009] A cutting rope, at least in part, is connected to the moving mechanism and extends beyond the turntable to rotate;

[0010] The cutting assembly further includes a first mounting part and a second mounting part. The first mounting part is detachably connected to the connector; the second mounting part is detachably connected to the cutting rope. When the moving mechanism is subjected to an external force, it moves relative to the turntable, and during the movement, the first mounting part is disconnected from the connector, and the second mounting part is disconnected from the cutting rope.

[0011] Secondly, this application provides a cutting device, comprising:

[0013] A connecting assembly, including a connector, wherein the motor assembly drives the connector to rotate;

[0014] The aforementioned cutting component is installed on the connector.

[0015] The cutting assembly provided in this application has the following beneficial effects:

[0016] In this embodiment, by using external force to drive the moving mechanism to move relative to the turntable, and during the movement of the moving mechanism, the first mounting part is disconnected from the connector and the second mounting part is disconnected from the cutting rope. Thus, the first mounting part can move relative to the connector, and the cutting rope is in a free-moving state. The first mounting part can be removed from the connector to remove the cutting assembly, and the cutting rope can also be removed from the second mounting part. This simplifies the disassembly of the cutting assembly and the cutting rope, thereby reducing disassembly time and improving disassembly efficiency. Attached Figure Description

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0037] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0038] The following is in conjunction with the appendix Figure 1 To be continued Figure 10 The following describes some embodiments of this application in detail. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0039] like Figure 1 and Figure 2 As shown, this application provides a cutting component 30 and a cutting device. The cutting device includes a motor component 10, a connecting component 20, and a cutting component 30. The connecting component 20 includes a connector 21. The motor component 10 drives the connector 21 to rotate. The cutting component 30 is detachably installed on the connector 21. When the cutting component 30 is installed on the connector 21, it can rotate with the connector 21 to achieve the grass-cutting function.

[0040] Furthermore, the motor assembly 10 includes a first housing 11, a second housing 12, and a motor 13. The motor 13 includes a motor body 131 and a motor spindle 132 connected to the motor body 131. The motor body 131 is the main structure of the motor 13 and is used to generate driving force to drive the motor spindle 132 to rotate. The first housing 11 and the second housing 12 are connected to form a first receiving cavity 14, and the motor body 131 is disposed in the first receiving cavity 14. The second housing 12 has a second receiving cavity 15 formed on the side opposite to the first housing 11. The motor spindle 132 passes through the second housing 12 and extends into the second receiving cavity 15. The connecting assembly 20 is disposed in the second receiving cavity 15, and the connecting member 21 is circumferentially fixed on the motor spindle 132.

[0041] In this embodiment, the connector 21 is fixed to the motor spindle 132. The space enclosed by the connector 21 and the second housing 12 shields the motor spindle 132, thereby protecting the motor spindle 132 and preventing grass from entering the second receiving cavity 15. This also prevents the cutting device from being entangled in grass on the motor spindle 132 when cutting grass.

[0042] like Figure 2 As shown, the connecting assembly 20 further includes a fastener 22, and the connector 21 is provided with a mounting hole 210. The motor spindle 132 passes through the mounting hole 210 and is fastened to the fastener 22 to fix the connector 21 around the motor spindle 132, so that the connector 21 can rotate with the motor spindle 132.

[0043] like Figure 2 As shown, further, the connector 21 is provided with a plurality of heat sinks 23 surrounding the motor spindle 132 on the side facing the motor body 131. By providing a plurality of heat sinks 23, the heat dissipation area of ​​the connector 21 is increased. When the connector 21 rotates, the heat sinks 23 rotate synchronously to blow air onto the motor body 131, enhance convection heat dissipation, improve the heat dissipation performance of the motor body 131, and prevent the motor 13 from overheating and affecting its lifespan.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, the cutting assembly 30 provided in this embodiment includes a turntable 31, a moving mechanism 32, and a cutting rope 33. The moving mechanism 32 is slidably disposed on the turntable 31, allowing the moving mechanism 32 to move relative to the turntable 31. At least a portion of the cutting rope 33 is connected to the moving mechanism 32 and extends beyond the turntable 31 to rotate, thereby rotating and cutting target objects such as lawns and vegetation under the drive of the turntable 31. The cutting assembly 30 also includes a first mounting part 34 and a second mounting part 35. The first mounting part 34 is detachably connected to the connector 21, and the second mounting part 35 is detachably connected to the cutting rope 33. When the moving mechanism 32 is subjected to external force, it moves relative to the turntable 31. During the movement, the first mounting part 34 is disconnected from the connector 21, allowing the first mounting part 34 to move relative to the connector 21, facilitating the disassembly and replacement of the cutting assembly 30. During the movement, the moving mechanism 32 also disconnects the second mounting part 35 from the cutting rope 33, allowing the cutting rope 33 to move freely, facilitating the disassembly and replacement of the cutting rope 33.

[0045] In this embodiment, by using an external force to drive the moving mechanism 32 to move relative to the turntable 31, the first mounting part 34 can be removed from the connector 21, thereby removing the cutting assembly 30. The cutting rope 33 can also be removed from the second mounting part 35, simplifying the disassembly of the cutting assembly 30 and the cutting rope 33, thereby reducing disassembly time and improving disassembly efficiency.

[0046] Furthermore, in practical applications, the moving mechanism 32 can be configured to move and reset when the external force is removed. Thus, during the installation of the cutting rope 33 and the cutting assembly 30, when the moving mechanism 32 is moved by external force, the first mounting part 34 can align with the connector 21, and the cutting rope 33 can be installed on the second mounting part 35. Subsequently, the external force applied to the moving mechanism 32 is removed, allowing it to reset. This results in the first mounting part 34 being connected to the connector 21, and the second mounting part 35 being connected to the cutting rope 33. In this case, the cutting assembly 30 is locked to the connector 21, and the cutting rope 33 is locked to the second mounting part 35. By first applying external force to move the moving mechanism 32 and then removing the external force to allow the moving mechanism 32 to reset itself for assembling the connector 21 and the cutting rope 33, the installation of the cutting assembly 30 and the cutting rope 33 can be simplified, thereby reducing installation time and improving installation efficiency.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, in the radial direction of the turntable 31 (e.g.) Figure 1 In the y-direction shown, the moving mechanism 32 has a first mounting part 34 on each of its opposite sides, which can improve the stability of the cutting assembly 30 when mounted on the connector 21.

[0048] In practical applications, the moving mechanism 32 can be configured to move first to the detachable position of the first mounting part 34 and then to the detachable position of the cutting rope 33, or first to the detachable position of the cutting rope 33 and then to the detachable position of the first mounting part 34, or move to a position where the first mounting part 34 and the cutting rope 33 can be detached simultaneously, depending on actual needs. For example, the displacement of the moving mechanism 32 can be changed by altering the radial dimension of the first mounting part 34 or by changing the magnitude of the applied external force, thereby enabling either the first mounting part 34 or the cutting rope 33 to be in a detachable state first, or both the first mounting part 34 and the cutting rope 33 to be in a detachable state simultaneously.

[0049] like Figure 2 , Figure 4 and Figure 8 As shown, in some embodiments, the moving mechanism 32 includes an elastic member 321 and at least one sliding member 322. The center of gravity of the sliding member 322 does not coincide with the rotation center of the turntable 31. The sliding member 322 is subjected to centrifugal force during the rotation of the turntable 31. The elastic member 321 can generate an elastic force that restricts the movement of the sliding member 322, so that the first mounting part 34 is connected to the connector 21 and the second mounting part 35 is connected to the cutting rope 33. The angle between the direction of the elastic force and the direction of the centrifugal force is 0°~45°. Thus, the direction of the centrifugal force on the sliding member 322 is approximately the same as the direction of the elastic force exerted by the elastic member 321 on the sliding member 322. As a result, during the rotation of the turntable 31, the force for maintaining the connection between the first mounting part 34 and the connector 21 is increased, and the force for maintaining the connection between the second mounting part 35 and the cutting rope 33 is increased.

[0050] For example, such as Figure 8 As shown, in an embodiment where there is one slider 322, one end of the elastic element 321 is connected to the slider 322, and the other end of the elastic element 321 is connected to the turntable 31. The direction of the elastic force is from the elastic element 321 to the slider 322. The center of gravity of the slider 322 is located on the side away from the rotation center of the turntable 31, and the straight line between the center of gravity of the slider 322 and the rotation center of the turntable 31 is parallel to the length direction of the elastic element 321. In this case, the direction of the centrifugal force on the slider 322 during the rotation of the turntable 31 is the same as the direction of the elastic force applied by the elastic element 321.

[0051] For example, such as Figure 4As shown, in an embodiment where there are two sliders 322, the two sliders 322 are located on opposite sides of the rotation center of the turntable 31. The direction of the centrifugal force of the slider 322 can be understood as the direction of the rotation center of the turntable 31 pointing towards the center of gravity of the slider 322. Furthermore, the angle between the direction of the centrifugal force and the direction of the elastic force on the slider 322 during the rotation of the turntable 31 is 45°. In this case, the direction of one component of the centrifugal force on the slider 322 is the same as the direction of the elastic force.

[0052] All of the above can increase the force maintaining the connection between the first mounting part 34 and the connector, and increase the force maintaining the connection between the second mounting part 35 and the cutting rope 33 during the rotation of the turntable 31. This ensures that the cutting assembly 30 and the connector 21 remain stably locked while the cutting assembly 30 rotates and the cutting rope 33 continuously cuts the target object, thus improving the working stability of the cutting assembly 30. For example, the elastic element 321 can be an elastic object, such as a spring.

[0053] like Figure 4 As shown, in some embodiments, there are two sliders 322, and an elastic element 321 is disposed between the two sliders 322. The two sliders 322 are symmetrically arranged about the rotation center of the turntable 31, which can reduce the shaking of the cutting assembly 30 during rotation.

[0054] like Figure 4 As shown, in some embodiments, the slider 322 is provided with a pressing part 323, the density of the pressing part 323 is greater than the density of the turntable 31, so that the center of gravity of the slider 322 is deviated from the rotation center of the turntable 31, so that the center of gravity of the slider 322 does not coincide with the rotation center of the turntable 31. The centrifugal force on the pressing part 323 is F1, and the centrifugal force on the edge of the turntable 31 is F2, wherein F1 is greater than F2.

[0055] It is understandable that the density of the pressing part 323 is greater than that of the turntable 31, which makes the pressing part 323 heavier than the part of the turntable 31 corresponding to the pressing part 323. As a result, the pressing part 323 experiences a greater centrifugal force when the turntable 31 rotates compared to the part of the turntable 31 corresponding to the pressing part 323. This can further increase the force of maintaining the connection between the first mounting part 34 and the connector 21, as well as the force of maintaining the connection between the second mounting part 35 and the cutting rope 33.

[0056] like Figure 2 , Figure 4 and Figure 5As shown, in one specific embodiment, based on an embodiment where each slider 322 is provided with a pressing part 323, and the number of sliders 322 is two, namely a first slider 322a and a second slider 322b. The first slider 322a is provided with a first through hole 324, and the second slider 322b is provided with a second through hole 325. The cutting rope 33 passes through the first through hole 324 and the second through hole 325. The elastic force applied by the elastic member 321 to the slider 322 can restrict the movement of the slider 322, so as to keep the first through hole 324 and the second through hole 325 misaligned along the length direction of the cutting rope 33, so that the cutting rope 33 can be squeezed and clamped. Based on this, since the density of the pressing part 323 is greater than that of the turntable 31, the pressing part 323 is heavier than the part of the turntable 31 corresponding to the pressing part 323. As a result, the pressing part 323 experiences a greater centrifugal force than the part of the turntable 31 corresponding to the pressing part 323. Moreover, the direction of this centrifugal force is away from the rotation center of the turntable 31. As a result, the sliding member 322 tends to move away from the rotation center of the turntable 31. While maintaining the misalignment of the first through hole 324 and the second through hole 325, the overlapping area of ​​the first through hole 324 and the second through hole 325 is reduced. This increases the force with which the two sliding members 322 clamp the cutting rope 33, preventing the cutting rope 33 from coming off when the turntable 31 rotates at high speed.

[0057] Furthermore, each sliding member 322 is provided with a first mounting portion 34, which extends into the annular space enclosed by the connecting member 21 and is installed on the connecting member 21 in a snap-fit ​​manner. Each sliding member 322 has a tendency to move away from the rotation center of the turntable 31, so that the first mounting portion 34 also has a tendency to move away from the rotation center of the turntable 31, thereby increasing the clamping force between the first mounting portion 34 and the connecting member 21. In this way, when the cutting assembly 30 rotates at high speed and the cutting rope 33 continuously cuts the target object, the cutting assembly 30 and the connecting member 21 remain stably locked, improving the working stability of the cutting assembly 30.

[0058] like Figures 8 to 10 As shown, in some embodiments, the turntable 31 is provided with a mounting groove 31a and a first mounting channel 31b. The moving mechanism 32 is disposed in the mounting groove 31a, and the cutting rope 33 passes through the first mounting channel 31b. The moving mechanism 32 includes a second mounting part 35 and an elastic member 321. The elastic member 321 can restrict the movement of the second mounting part 35, so that the second mounting part 35 covers at least a portion of the first mounting channel 31b, so that the second mounting part 35 presses a portion of the cutting rope 33 against and connects it to the first mounting channel 31b. During the movement of the moving mechanism 32 under the action of external force, it avoids the first mounting channel 31b and drives the second mounting part 35 to move, so that the cutting rope 33 is disconnected from the first mounting channel 31b, so that the cutting rope 33 can pass through the first mounting channel 31b and can also move freely.

[0059] In practical application, the moving mechanism 32 moves under the action of external force, driving the second mounting part 35 to move and compress the elastic element 321, so that the moving mechanism 32 avoids the first mounting channel 31b. Thus, when viewed from the direction from the mounting groove 31a to the first mounting channel 31b, the end of the first mounting channel 31b is fully exposed. At this time, the cutting rope 33 can be removed or installed. After the cutting rope 33 is installed, the external force on the moving mechanism 32 is removed. Due to the action of the elastic element 321, the second mounting part 35 can be pushed to reset, so that at least a portion of the second mounting part 35 and the first mounting channel 31b coincide along the length direction of the cutting rope 33. That is, when viewed from the direction from the mounting groove 31a to the first mounting channel 31b, the second mounting part 35 blocks at least a portion of the first mounting channel 31b. Thus, the end face of the second mounting part 35 and the first mounting channel 31b facing the second mounting part 35 together clamp the portion of the cutting rope 33 located between the second mounting part 35 and the first mounting channel 31b.

[0060] For example, such as Figure 8 As shown, the turntable 31 is provided with two first installation channels 31b, which are located on opposite sides of the installation groove 31a. Part of the cutting rope 33 is located in the installation groove 31a, and the two ends of the cutting rope 33 pass through the two first installation channels 31b and extend out from opposite sides of the turntable 31 in the radial direction.

[0061] Furthermore, the second mounting part 35 has two corners (not shown), which are arranged along the length of the cutting rope 33. The second mounting part 35 presses against the cutting rope 33 and squeezes the portion of the cutting rope 33 corresponding to the corners to form a bend (not shown), which can stabilize the connection of the cutting rope 33.

[0062] like Figure 8 and Figure 9 As shown, in one embodiment, the moving mechanism 32 is provided with a notch 32a. During the movement of the moving mechanism under the action of external force, the notch 32a avoids the cutting rope 33 and also avoids the first installation channel 31b, so that the port of the first installation channel 31b is exposed from one side of the notch 32a, making it convenient for the cutting rope 33 to pass through the notch 32a.

[0063] Furthermore, in an embodiment where the moving mechanism 32 includes a slider 322, the slider 322 includes a body 3221, a connecting portion 3222, and a second mounting portion 35 connected in sequence along the radial direction of the cutting rope 33. The body 3221, the connecting portion 3222, and the second mounting portion 35 form a notch 32a. The end of the slider 322 away from the second mounting portion 35 (which can be understood as a pressing portion 323) protrudes from the turntable 31 to facilitate pressing the slider 322 when an external force is applied to it.

[0064] like Figure 1 and Figure 2 As shown, in some embodiments, the second mounting part 35 includes a second mounting channel 351 provided in the moving mechanism 32, a portion of the cutting rope 33 is connected to the second mounting channel 351, and the two ends of the cutting rope 33 respectively pass through the two ends of the second mounting channel 351 and extend out of the radial sides of the turntable 31 respectively; during the movement of the moving mechanism 32 under the action of external force, the cutting rope 33 is disconnected from the second mounting channel 351.

[0065] It is understandable that when the moving mechanism 32 is not subjected to external force, it can fix part of the cutting rope 33 within the second mounting channel 351. In this case, the moving mechanism 32 is in a locked state, preventing the cutting rope 33 from moving freely. However, by applying external force, the locked moving mechanism 32 can be switched to a movable moving mechanism 32. During the movement of the moving mechanism 32 relative to the turntable 31 under the action of external force, the cutting rope 33 is released, and at this time, the cutting rope 33 can be removed.

[0066] In practical applications, the moving mechanism 32 can be configured to move and reset when the external force is removed. Thus, after the first mounting part 34 is connected to the connector 21 and the cutting rope 33 is installed in the second mounting channel 351, the external force applied to the moving mechanism 32 can be removed, thereby switching the movable moving mechanism 32 to a locked state. Consequently, the cutting rope 33 is fixed in the second mounting channel 351, so that the cutting rope 33 and the second mounting channel 351 are in a connected state.

[0067] Furthermore, in the embodiment where the first mounting part 34 is disposed on the moving mechanism 32, when the moving mechanism 32 is not subjected to external force, the first mounting part 34 is mounted on the connector 21 under the action of the moving mechanism 32. Specifically, the first mounting part 34 is mounted on the connector 21 in a snap-fit ​​manner.

[0068] like Figure 1 and Figure 4 As shown, in some embodiments, the second mounting channel 351 is disposed on the moving mechanism 32. When the cutting rope 33 and the second mounting channel 351 are connected, the second mounting channel 351 is located along the length direction of the cutting rope 33 (e.g., ...). Figure 4The cross-sectional area along the x-direction (as shown) is S1. When the cutting rope 33 and the second mounting channel 351 are in a disconnected state, the cross-sectional area of ​​the second mounting channel 351 along the length of the cutting rope 33 is S2, where S1 is less than S2. This arrangement allows the cutting rope 33 to be stably compressed within the second mounting channel 351 when in the connected state, and allows the cutting rope 33 to be withdrawn from the second mounting channel 351 when in a detachable state. Furthermore, when the cutting rope 33 is in the detachable state, the axial cross-sectional area of ​​the cutting rope 33 is S3, and S3 is less than S2, facilitating the removal of the cutting rope 33.

[0069] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the second mounting channel 351 is provided on the moving mechanism 32. The vertical distance between the second mounting channel 351 and the bottom of the turntable 31 is H1, and the vertical distance between the top surface of the turntable 31 and the bottom of the turntable 31 is H2. H1 is greater than H2. Thus, from the top view, i.e. from the direction from the connector 21 to the turntable 31, the second mounting channel 351 is located above the turntable 31, so that the turntable 31 does not block the cutting rope 33, which facilitates the assembly and disassembly of the cutting rope 33.

[0070] like Figure 2 , Figure 4 and Figure 5 As shown, combined with Figure 7In some embodiments, the moving mechanism 32 includes an elastic element 321, a first sliding element 322a, and a second sliding element 322b. The elastic element 321 is disposed between the first sliding element 322a and the second sliding element 322b. Both the first sliding element 322a and the second sliding element 322b are slidably mounted on the turntable 31. The first sliding element 322a has a first through hole 324, and the second sliding element 322b has a second through hole 325. The first through hole 324 and the second through hole 325 communicate to form a second mounting channel 351. The cutting rope 33 passes through the first through hole 324 and the second through hole 325. The first sliding element 322a and the second sliding element 322b are restricted by the elastic element 321. The movement maintains the misalignment of the first through hole 324 and the second through hole 325, causing the portion of the cutting rope 33 located between the first sliding member 322a and the second sliding member 322b to be squeezed and clamped, forming a first bend 331. This connects the cutting rope 33 to the second mounting channel 351 and secures the cutting rope 33. During the relative movement of the first sliding member 322a and the second sliding member 322b under external force, the first through hole 324 and the second through hole 325 overlap, disengaging the cutting rope 33 from the second mounting channel 351. At this point, the cutting rope 33 is released and can move freely, facilitating its removal from the second mounting channel 351. In this embodiment, when the cutting rope 33 is connected to the second mounting channel 351, the elastic member 321 can provide a preload force, keeping the portion of the cutting rope 33 located between the first sliding member 322a and the second sliding member 322b clamped.

[0071] Furthermore, both the first sliding member 322a and the second sliding member 322b are provided with a first mounting part 34. During the relative movement of the first sliding member 322a and the second sliding member 322b under the action of external force, the first mounting part 34 provided on the first sliding member 322a and the first mounting part 34 provided on the second sliding member 322b are also driven to move closer to each other, so that the first mounting part 34 is detached from the connecting member 21, thereby allowing the cutting assembly 30 to be disassembled.

[0072] In practical applications, during the installation of the cutting rope 33 and the cutting assembly 30, external force can first be applied along the radial direction of the turntable 31 (e.g., Figure 4Press the first slider 322a and the second slider 322b (in the y-direction shown) to move the first slider 322a and the second slider 322b, thereby driving the two first mounting parts 34 closer together and aligning the first through hole 324 and the second through hole 325. Then, mate the first mounting part 34 with the connector 21 and pass the cutting rope 33 through the first through hole 324 and the second through hole 325. After adjusting the length of the cutting rope 33 extending out of the second mounting channel 351, remove the external force. Due to the pressing of the first slider 322a and the second slider... When the moving member 322b is in motion, the elastic member 321 is located between the first sliding member 322a and the second sliding member 322b. It will be compressed and undergo elastic deformation to generate an elastic force. After the external force is removed, the elastic member 321 rebounds and acts on the first sliding member 322a and the second sliding member 322b, causing the first sliding member 322a and the second sliding member 322b to move and reset. This causes the two first mounting parts 34 to move away from each other, so that the first mounting parts 34 are engaged with the connector 21. It also causes the first through hole 324 and the second through hole 325 to be misaligned, so that the cutting rope 33 is clamped. This embodiment provides a simple way to install the cutting assembly 30 and the cutting rope 33, which can also reduce installation time and improve installation efficiency.

[0073] Furthermore, when disassembling the cutting rope 33 and the cutting assembly 30, external force is used to press the first sliding member 322a and the second sliding member 322b radially along the turntable 31, causing the first sliding member 322a and the second sliding member 322b to move, thereby driving the two first mounting parts 34 to move closer to each other and making the first through hole 324 and the second through hole 325 coincide. This allows the first mounting part 34 to disengage from the connector 21, and the cutting rope 33 to be released, thus enabling the disassembly of the cutting assembly 30 and the cutting rope 33. This embodiment provides a simple method for disassembling the cutting assembly 30 and the cutting rope 33, while also reducing disassembly time and improving disassembly efficiency.

[0074] like Figure 1 and Figure 2 As shown, for example, the cutting rope 33 is located below the second receiving cavity 15. The connector 21 rotates under the drive of the motor spindle 132, and drives the turntable 31 to rotate, thereby driving the cutting rope 33 clamped in the second mounting channel 351 to rotate, so as to cut the target object.

[0075] like Figure 4 and Figure 5 As shown, in some embodiments, the turntable 31 is provided with an assembly groove 311, a first assembly hole 312, and a second assembly hole 313. Both the first assembly hole 312 and the second assembly hole 313 communicate with the assembly groove 311 in the radial direction of the turntable 31 (e.g., ...). Figure 5In the y-direction shown, the first mounting hole 312 and the second mounting hole 313 are located on opposite sides of the cutting rope 33. Specifically, the first mounting hole 312 and the second mounting hole 313 are located on opposite radial sides of the cutting rope 33. The first sliding member 322a is provided with a first pressing part 323a, and the second sliding member 322b is provided with a second pressing part 323b. Both the first sliding member 322a and the second sliding member 322b are located in the mounting groove 311. The first pressing part 323a passes through the first mounting hole 312, and the second pressing part 323b passes through the second mounting hole 313. The first pressing part 323a and the second pressing part 323b can approach each other under the action of external force, so as to drive the first sliding member 322a and the second sliding member 322b to move respectively.

[0076] In this embodiment, a portion of the first sliding member 322a, a portion of the second sliding member 322b, and the elastic member 321 are all housed in the assembly groove 311. The first pressing portion 323a connected to the first sliding member 322a and the second pressing portion 323b connected to the second sliding member 322b respectively pass through the first assembly hole 312 and the second assembly hole 313 provided on the assembly groove 311. Thus, in the radial direction of the turntable 31, the first sliding member 322a and the first pressing portion 323a form a locking position that engages with a groove wall of the assembly groove 311, and the second sliding member 322b and the second pressing portion... 323b forms a locking position that engages with the other wall of the assembly slot 311, thereby enabling the first sliding member 322a and the second sliding member 322b to be detachable from the turntable 31, and also improving the connection stability between the first sliding member 322a, the second sliding member 322b and the turntable 31. At the same time, the first pressing part 323a and the second pressing part 323b protrude from the turntable 31 radially, making it convenient to use external force to press the first pressing part 323a and the second pressing part 323b radially along the turntable 31, so that the first pressing part 323a and the second pressing part 323b are brought closer to each other.

[0077] It should be noted that the first pressing part 323a of the first sliding member 322a and the second pressing part 323b of the second sliding member 322b can both be understood as the pressing part 323 of the sliding member 322. That is, the density of the first pressing part 323a and the density of the second pressing part 323b can be the same, and the density of the first pressing part 323a and the density of the second pressing part 323b are both greater than the density of the turntable 31. Therefore, when the turntable 31 rotates, the centrifugal force on the first pressing part 323a and the centrifugal force on the second pressing part 323b are both greater than the centrifugal force on the edge of the turntable 31, thereby increasing the force to hold the cutting rope 33 in place and increasing the connection stability between the cutting assembly 30 and the connector.

[0078] like Figure 2 , Figure 3 and Figure 5As shown, for example, both the first sliding member 322a and the second sliding member 322b are provided with a first mounting part 34. The first mounting part 34 is located above the assembly groove 311. When the first mounting part 34 is engaged with the connector 21, the bottom surface of the connector 21 abuts against the upper surface of the turntable 31, thereby reducing the axial shaking of the turntable 31.

[0079] like Figure 2 , Figure 4 and Figure 6 As shown, combined with Figure 7 In some embodiments, a second mounting channel 351 is provided on the moving mechanism 32, and the turntable 31 is also provided with a first channel 314 for the cutting rope 33 to pass through. The first channel 314 and the second mounting channel 351 are along the radial direction of the turntable 31 (e.g., Figure 6 Arranged in the y-direction shown, the cutting rope 33 has a second bend 332. When the cutting rope 33 and the second mounting channel 351 are connected, the first channel 314 and the second mounting channel 351 are misaligned so that the second bend 332 is squeezed between the first channel 314 and the second mounting channel 351, thereby clamping the second bend 332. When the cutting rope 33 is disconnected from the second mounting channel 351, the first channel 314 and the second mounting channel 351 overlap, thereby allowing the cutting rope 33 to be pulled out from the first channel 314 and the second mounting channel 351.

[0080] For example, in an embodiment where a second mounting channel 351 is formed by combining a first through hole 324 and a second through hole 325, the first through hole 324 is located between the first channel 314 and the second through hole 325. The cutting rope 33 has a second bend 332. When the cutting rope 33 and the second mounting channel 351 are connected, the first channel 314 and the first through hole 324 are misaligned so that the second bend 332 is squeezed between the first channel 314 and the first through hole 324, thereby clamping the second bend 332.

[0081] It is understood that when the moving mechanism 32 is in the locked cutting rope 33 state, the first channel 314 and the first through hole 324 are misaligned along the length direction of the cutting rope 33, so that the part of the cutting rope 33 located between the first channel 314 and the first through hole 324 is squeezed by the inner sidewall of the first channel 314 and the inner sidewall of the first through hole 324, and bends to form a second bend 332.

[0082] like Figure 2 , Figure 4 and Figure 6 As shown, combined with Figure 7 In some embodiments, a second mounting channel 351 is provided on the moving mechanism 32, and the turntable 31 is also provided with a second channel 315 for the cutting rope 33 to pass through. The second channel 315 and the second mounting channel 351 are along the radial direction of the turntable 31 (e.g., Figure 7Arranged in the y-direction shown, the cutting rope 33 has a third bend 333. When the cutting rope 33 and the second mounting channel 351 are connected, the second channel 315 and the second mounting channel 351 are misaligned, and the third bend 333 is squeezed between the second channel 315 and the second mounting channel 351. When the cutting rope 33 is disconnected from the second mounting channel 351, the second channel 315 and the second mounting channel 351 overlap, and it can be pulled out from the second channel 315 and the second mounting channel 351.

[0083] In an exemplary embodiment where a second mounting channel 351 is formed by combining a first through hole 324 and a second through hole 325, the second through hole 325 is located between the second channel 315 and the first through hole 324. The cutting rope 33 has a third bend 333. When the cutting rope 33 and the second mounting channel 351 are connected, the second channel 315 and the second through hole 325 are misaligned, and the third bend 333 is squeezed between the second channel 315 and the second through hole 325, thereby clamping the third bend 333.

[0084] It is understood that when the moving mechanism 32 is in the locked cutting rope 33 state, the second channel 315 and the second through hole 325 are misaligned along the length direction of the cutting rope 33, so that the part of the cutting rope 33 located between the second channel 315 and the second through hole 325 is squeezed by the inner wall of the second channel 315 and the inner wall of the second through hole 325, and bends to form a third bend 333.

[0085] In this embodiment, in addition to the first bend 331 formed by the compression of part of the cutting rope 33, it may also have a second bend 332 and / or a second bend 332 to increase the clamping force of the cutting rope 33.

[0086] like Figure 2 , Figure 4 and Figure 6 As shown, combined with Figure 7 In one embodiment, the cutting rope 33 has a first bend 331, a second bend 332, and a second bend 332. A first channel 314 is provided on the turntable 31 at the position corresponding to the first through hole 324, and a second channel 315 is provided on the turntable 31 at the position corresponding to the second through hole 325. The first channel 314 and the second channel 315 are connected to the assembly groove 311. When the cutting rope 33 and the second mounting channel 351 are in a connected state, the first bend 331, the second bend 332, and the second bend 332 are clamped and squeezed respectively, which can increase the force of fixing the cutting rope 33. When the cutting rope 33 is disconnected from the second mounting channel 351, the first channel 314, the second mounting channel 351, and the second channel 315 are on the same straight line. At this time, the cutting rope 33 is released and can be pulled away from the first channel 314, the second mounting channel 351, and the second channel 315.

[0087] For example, the first channel 314 is a through hole or a groove, and the second channel 315 is a through hole or a groove.

[0088] For example, in the thickness direction of the turntable 31, the wall thickness of the first channel 314 and the second channel 315 has a certain thickness, which can be designed as needed, and can enable the first channel 314 to support a portion of the cutting rope 33 housed in the first channel 314, and the second channel 315 to support a portion of the cutting rope 33 housed in the second channel 315, so that the portion of the cutting rope 33 extending out of the turntable 31 remains straight and does not bend.

[0089] like Figure 6 and Figure 7 As shown, exemplarily, in the length direction of the cutting rope 33 (which can be understood as the radial direction of the turntable 31, i.e., as...) Figure 6 In the y-direction shown, the first channel 314, the first through hole 324, the second through hole 325, and the second channel 315 each have a first port 316, a second port 317, and a hole segment 318 located between the first port 316 and the second port 317. The inner diameter of the first port 316 and the inner diameter of the second port 317 gradually increase in the direction away from the hole segment 318 to facilitate the passage of the cutting rope 33.

[0090] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the first slider 322a includes a first sliding body 3223 and a first extension 3224. The first extension 3224 is connected to the first sliding body 3223, and the first sliding body 3223 and the first extension 3224 are arranged along the length direction of the cutting rope 33 (e.g., Figure 5 (shown in the x-direction); the second slider 322b includes a second sliding body 3225 and a second extension 3226. The second extension 3226 is connected to the second sliding body 3225. The second sliding body 3225 and the second extension 3226 are arranged along the length direction of the cutting rope 33. Thus, the first sliding body 3223 and the second extension 3226 are arranged opposite to each other, and the second sliding body 3225 and the first extension 3224 are arranged opposite to each other. A first through hole 324 is provided in the first sliding body 3223, and a second through hole 325 is provided in the second sliding body 3225.

[0091] Furthermore, the elastic element 321 includes a first elastic element 3211 and a second elastic element 3212. The first elastic element 3211 and the second elastic element 3212 are offset along the length direction of the cutting rope 33. One end of the first elastic element 3211 elastically abuts against the first sliding body 3223, and the other end of the first elastic element 3211 elastically abuts against the second extension 3226. One end of the second elastic element 3212 elastically abuts against the second sliding body 3225, and the other end of the second elastic element 3212 elastically abuts against the first extension 3224. Thus, the first elastic element 3211 and the second elastic element 3212 provide elastic resistance to restrict the movement of the first sliding member 322a and the second sliding member 322b, so that the cutting rope 33 is subjected to pretension, thereby keeping the cutting rope 33 in a clamped state.

[0092] Furthermore, both the first sliding body 3223 and the second sliding body 3225 are provided with a first mounting portion 34. When the first elastic member 3211 is compressed by the first sliding body 3223 and the second extension portion 3226, and the second elastic member 3212 is compressed by the second sliding body 3225 and the first extension portion 3224, the first sliding member 322a and the second sliding member 322b tend to move away from each other. As a result, the first mounting portion 34 tends to move away from the rotation center of the turntable 31, thereby improving the engagement stability between the first mounting portion 34 and the connector 21.

[0093] For example, the first slider 322a and the second slider 322b have the same construction, and the first elastic member 3211 and the second elastic member 3212 can both be elastic objects, such as springs.

[0094] like Figure 4 and Figure 5 As shown, for example, the first pressing part 323a is integrally formed and connected to the side of the first sliding body 3223 opposite to the rotation center of the turntable 31, so as to improve the connection stability between the first pressing part 323a and the first sliding body 3223. The second pressing part 323b is integrally formed and connected to the side of the second sliding body 3225 opposite to the rotation center of the turntable 31, so as to improve the connection stability between the second pressing part 323b and the second sliding body 3225.

[0095] like Figure 4 and Figure 5 As shown, in some embodiments, the first extension 3224 is provided with a first groove 3227, and a portion of the second elastic member 3212 is received in the first groove 3227, effectively preventing the second elastic member 3212 from coming out of the assembly groove 311 when compressed; and / or, the second extension 3226 is provided with a second groove (not shown), and a portion of the first elastic member 3211 is received in the second groove, effectively preventing the first elastic member 3211 from coming out of the assembly groove 311 when compressed.

[0096] Furthermore, the first sliding body 3223 has a third groove (not shown) on the side facing the second extension 3226. One end of the first elastic member 3211 is received in the second groove, and the other end of the first elastic member 3211 is received in the third groove, effectively preventing the first elastic member 3211 from dislodging from the mounting groove 311 when compressed. The second sliding body 3225 has a fourth groove 3228 on the side facing the first extension 3224. One end of the second elastic member 3212 is received in the first groove 3227, and the other end of the second elastic member 3212 is received in the fourth groove 3228, effectively preventing the second elastic member 3212 from dislodging from the mounting groove 311 when compressed.

[0097] like Figure 4 and Figure 5 As shown, exemplarily, the first extension 3224 includes a first extension plate 32241 and a second extension plate 32242 connected at an included angle. The first extension plate 32241 is located on the side of the second extension plate 32242 facing away from the turntable 31. The first extension plate 32241, the second extension plate 32242, and the bottom wall of the mounting groove 311 enclose and form a first groove 3227. The second extension 3226 has the same structure as the first extension 3224.

[0098] Combination Figure 4 and Figure 5 In some embodiments, the first extension 3224 extends a first protrusion (not shown) towards the second sliding body 3225. A portion of the second elastic member 3212 surrounds the first protrusion. The length of the first protrusion in the longitudinal direction of the second elastic member 3212 is L3. When the first through hole 324 coincides with the second through hole 325, the distance between the first extension 3224 and the second sliding body 3225 is L4, where L3 ≤ L4. The formation of the first protrusion ensures that the second elastic member 3212 can be compressed and effectively prevents the second elastic member 3212 from dislodging from the mounting groove 311 when compressed.

[0099] Combination Figure 4 and Figure 5 In some embodiments, the second extension 3226 extends a second protrusion towards the side of the first sliding body 3223, and a portion of the first elastic member 3211 surrounds the second protrusion. The length of the second protrusion is L5 along the length direction of the first elastic member 3211. When the first through hole 324 and the second through hole 325 coincide, the distance between the second extension 3226 and the first sliding body 3223 is L6, where L5 ≤ L6. The formation of the second protrusion ensures that the first elastic member 3211 can be compressed and effectively prevents the first elastic member 3211 from dislodging from the mounting groove 311 when compressed.

[0100] For example, both the first protrusion and the second protrusion can be columnar protrusions.

[0101] like Figure 2 and Figure 3 As shown, in some embodiments, the first mounting portion 34 is located on the side of the turntable 31 facing the connector 21, and is spaced apart from the turntable 31. It can be understood that, viewed from above, i.e., from the direction from the connector 21 to the turntable 31, the first mounting portion 34 is above the turntable 31. Specifically, in conjunction with... Figure 5 The first mounting part 34 is located above the assembly slot 311, which helps the first mounting part 34 to extend into the annular space formed by the connector 21 and engage with the connector 21 when assembling the moving mechanism 32 and the connector 21.

[0102] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the first mounting part 34 includes a latching protrusion 341, and the connector 21 is provided with a latching groove 211 corresponding to the latching protrusion 341. Specifically, the latching groove 211 is provided on the inner peripheral wall of the connector 21, and the latching protrusion 341 is engaged with the latching groove 211 to realize the engagement of the first mounting part 34 and the connector 21.

[0103] For example, the first slider 322a extends out a locking protrusion 341 integrally from the side facing away from the rotation center of the turntable 31, and the second slider 322b extends out a locking protrusion 341 integrally from the side facing away from the rotation center of the turntable 31.

[0104] like Figure 1 and Figure 2 As shown above, the cutting device provided in this application embodiment uses the cutting component 30 of any of the above embodiments. By applying external force to the moving mechanism 32, the cutting component 30 can be removed from the connector 21, and the cutting rope 33 can be removed from the second mounting part 35, thereby realizing the disassembly of the cutting component 30 and the cutting rope 33.

[0105] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the content of this application's specification and drawings under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
