Description

Technical Field

[0001] This invention relates to the field of mechanical energy conversion technology, and more specifically to a torque amplification mechanism. Background Technology

[0002] A torque amplifier is a mechanical device that amplifies the torque of a rotating shaft. In large or industrial-grade torque amplifiers, power input is typically provided by mechanical devices (such as electric motors or hydraulic cylinders). However, this method results in significant energy loss. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a torque amplification mechanism.

[0004] To achieve the above objectives, the technical solution adopted by the present invention includes:

[0005] The first and second swashplates are parallel to each other and form a receiving space. The first and second swashplates are configured to swing about a diameter axis. Corresponding force application areas and reaction force areas are formed on the first and second swashplates.

[0006] An output shaft and a torque transmission assembly, wherein one end of the output shaft passes axially through the second swashplate to enter the receiving space, and the torque transmission assembly is configured within the receiving space to surround the output shaft, the torque transmission assembly abuts against the surfaces of the first swashplate and the second swashplate respectively, and the output shaft is rotated, and the torque transmission assembly is driven to move in a path direction parallel to the outer periphery of the first swashplate and the second swashplate and rotate around the output shaft;

[0007] A force-applying component applies a static external force toward the second swashplate to the force-applying area, such that: after the first swashplate is in a stationary position, when the torque transmission component moves to the force-applying area within the accommodating space, the torque transmission component receives a pushing force toward the second swashplate and converts the pushing force into mechanical kinetic energy, which is then transmitted to the output shaft to amplify the torque; or, when the torque transmission component moves to the reaction force area, the torque transmission component receives a reaction force toward the first swashplate and converts the reaction force into mechanical kinetic energy, which is then transmitted to the output shaft to amplify the torque.

[0008] A static external force is applied to the force application area of ​​the first swashplate by a force applicator. When the torque transmission component moves to the force application area within the housing assembly, the force applicator generates a pushing force on the torque transmission component in the direction from the first swashplate to the second swashplate. The torque transmission component converts this pushing force into mechanical kinetic energy, which is applied to the output shaft, thus increasing the torque of the output shaft without changing its rotational speed. Simultaneously, when the torque transmission component moves to the reaction force area within the housing assembly, the reaction force generated on the first and second swashplates in the direction from the second swashplate to the first swashplate acts on the torque transmission component. At this time, the torque transmission component converts the reaction force into mechanical kinetic energy, which is applied to the output shaft, thus increasing the torque of the output shaft without changing its rotational speed. Through this configuration, a static external force can be applied to the force application area while the output shaft speed is kept constant by the servo motor control. The mechanical energy input of the output shaft by the static external force is used to amplify the torque of the output shaft, effectively reducing energy loss.

[0009] In the preferred embodiment of the torque amplification mechanism described above, the torque transmission component includes at least:

[0010] A transmission rod, the two ends of which abut against the first swashplate and the second swashplate respectively, and a first rack and a second rack are formed on the two side surfaces of the transmission rod respectively;

[0011] A first full gear and a first half gear rotate synchronously, the first half gear being intermittently meshed with the first rack; a second full gear and a second half gear rotate synchronously, the second half gear being intermittently meshed with the second rack; a first bevel gear and a third full gear rotate synchronously, the third full gear being meshed with the first full gear and the second full gear, and the first bevel gear being meshed with a second bevel gear disposed at the end of the output shaft.

[0012] In the preferred embodiment of the torque amplification mechanism described above, the first swashplate is provided with a fixed limiting block on the surface near the second swashplate, and the second swashplate is provided with a fixed limiting block on the surface away from the first swashplate. The limiting block is used to limit the swing angle of the first swashplate and the second swashplate.

[0013] In the preferred embodiment of the torque amplification mechanism described above, the force application member includes at least a contact rod, a water reservoir, and a baffle. The contact rod has a first end and a second end facing each other. An opening is formed on the side of the water reservoir. The top of the baffle is hinged to the opening. The water reservoir is filled with liquid through a membrane. The first end of the contact rod is hinged to the force application area of ​​the first swashplate, and the second end is hinged to the lower part of the baffle. By means of liquid pressure, the baffle moves toward the first swashplate to bring the first swashplate to a stationary position via the contact rod.

[0014] In the preferred embodiment of the torque amplification mechanism described above, the force application member is a drive cylinder whose extended shaft end abuts against the force application area.

[0015] In the preferred embodiment of the torque amplification mechanism described above, the two ends of the transmission rod are respectively rolledly connected to the first swashplate and the second swashplate.

[0016] In the preferred embodiment of the torque amplification mechanism described above, a sleeve is disposed on the output shaft, and the transmission rod passes through the sleeve.

[0017] In the preferred embodiment of the torque amplification mechanism described above, a pulley is installed on the portion of the output shaft that does not extend into the accommodating space.

[0018] In the preferred embodiment of the torque amplification mechanism described above, the first swashplate and the second swashplate are each provided with a rotating shaft along their diameter direction, and the first swashplate and the second swashplate can swing through the rotating shaft.

[0019] In the preferred embodiment of the torque amplification mechanism described above, the tilt angle between the first swashplate and the second swashplate is 15-45°.

[0020] The beneficial effects of this invention are that, by utilizing the water pressure in the reservoir to lift the bottom end of the baffle upwards, the abutting rod abuts the force application area of ​​the first swashplate to a stationary position, ensuring that the transmission rod in the force application area always has a leftward pushing force, and the transmission rod in the reaction force area always has a rightward reaction force. This arrangement ensures that the transmission rod in the force application area always has a tendency to move to the left, and the transmission rod in the reaction force area always has a tendency to move to the right. This tendency can indirectly act on the output shaft to amplify the torque of the output shaft, thereby increasing the applicability of this application. Simultaneously, by utilizing atmospheric pressure in the water contained in the membrane, and then through the baffle and abutting rod, a static external force is applied to the first swashplate, reducing the work done by external workpieces and reducing energy loss.

[0035] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] Example 1:

[0037] like Figures 1 to 10 As shown, the torque amplification mechanism of the present invention includes: a first swashplate 1 and a second swashplate 2, the first swashplate 1 and the second swashplate 2 are parallel to each other and form an accommodating space 3, the first swashplate 1 and the second swashplate 2 are configured to swing about their respective diameters as axes, and corresponding force application areas 41 and reaction force areas 42 are formed on the first swashplate 1 and the second swashplate 2.

[0038] The output shaft 5 and torque transmission assembly 6 are provided. One end of the output shaft 5 passes through the second swashplate 2 along the axial direction to enter the receiving space 3. The torque transmission assembly 6 is configured to surround the output shaft 5 in the receiving space 3. The torque transmission assembly 6 abuts against the surfaces of the first swashplate 1 and the second swashplate 2 respectively. When the output shaft 5 is rotated, the torque transmission assembly 6 is driven to move in a path direction parallel to the outer periphery of the first swashplate 1 and the second swashplate 2 and rotate around the output shaft 5.

[0039] Force application component 7 applies a static external force toward the second swashplate 2 to force application area 41, so that: after the first swashplate 1 is in a stationary position, when the torque transmission component 6 moves to the force application area 41 within the accommodating space 3, the torque transmission component 6 receives the pushing force toward the second swashplate 2 and converts the pushing force into mechanical kinetic energy, which is then transmitted to the output shaft 5 to amplify the torque; or, when the torque transmission component 6 moves to the reaction force area 42, the torque transmission component 6 receives the reaction force toward the first swashplate 1 and converts the reaction force into mechanical kinetic energy, which is then transmitted to the output shaft 5 to amplify the torque.

[0040] See Figures 1 to 4 Both the first swashplate 1 and the second swashplate 2 are disc-shaped. The first swashplate 1 and the second swashplate 2 are parallel to each other and placed at a certain angle so that a accommodating space 3 for accommodating the output shaft 5 and the torque transmission assembly 6 is formed between the first swashplate 1 and the second swashplate 2. The cross-section of the accommodating space 3 is approximately parallelogram-shaped. Along the diameter direction of the first swashplate 1 and the second swashplate 2, the first swashplate 1 and the second swashplate 2 are configured to swing synchronously along their respective diameter directions. The first swashplate 1 and the second swashplate 2 form a force application area 41 and a reaction force area 42 on both sides of the radial axis, respectively.

[0041] See Figure 2The output shaft 5 has a first end and a second end. The first end extends horizontally through the middle of the second swashplate 2 into the receiving space 3, and the second end is located outside the receiving space 3. The output shaft 5 and the part extending into the receiving space 3 are connected to a torque transmission assembly 6. By controlling the rotation of the output shaft 5, the torque transmission assembly 6 can rotate around the output shaft 5 while its two ends rotate in a path direction parallel to the outer periphery of the first disk and the second swashplate 2. That is, while rotating, the torque transmission assembly 6 can reciprocate along the axis of the output shaft 5.

[0042] See Figure 4 , Figure 10 The force application component 7 is disposed on the side of the first swashplate 1 away from the second swashplate 2. The force application component 7 always applies a static external force to the force application area 41 of the first swashplate 1. Due to the contact between the torque transmission component 6 and the force application area 41 of the first swashplate 1 in the accommodating space 3, the first swashplate 1 can always remain stationary.

[0043] During operation, a static external force is first applied to the force application area 41 of the first swashplate 1 using the force application component 7. The torque transmission component 6 then abuts the force application area 41 and the reaction force area 42, so that the reaction force area 42 receives a reaction force adapted to the static external force. Subsequently, the output shaft 5 is controlled to rotate, which drives the torque transmission component 6 to work. While rotating around the output shaft 5 as its central axis, the two ends of the torque transmission component 6 can rotate in a path direction parallel to the outer circumference of the first swashplate 1 and the second swashplate 2, so that the torque transmission component 6 achieves reciprocating motion left and right along the axial direction of the output shaft 5. When the torque transmission component 6 moves to the force application area 41 within the housing component... The force application component 7 can generate a pushing force on the torque transmission component 6 in the direction from the first swashplate 1 to the second swashplate 2. The torque transmission component 6 can convert this pushing force into mechanical kinetic energy and apply it to the output shaft 5, thereby increasing the torque of the output shaft 5 without changing its rotational speed. Simultaneously, when the torque transmission component 6 moves to the reaction force zone 42 within the housing, the reaction force generated on the first swashplate 1 and the second swashplate 2 in the direction from the second swashplate 2 to the first swashplate 1 will act on the torque transmission component 6. At this time, the torque transmission component 6 can convert the reaction force into mechanical kinetic energy and apply it to the output shaft 5, thereby increasing the torque of the output shaft 5 without changing its rotational speed. Through this configuration, a static external force can be applied to the force application zone while the servo motor 9 controls the output shaft 5 to maintain a constant rotational speed. This static external force is used to input mechanical energy into the output shaft 5, thereby amplifying the torque of the output shaft 5 and effectively reducing energy loss. The static external force can be water pressure or the pressure of a heavy object.

[0044] It should be noted that the torque transmission assembly 6 has at least two sets and is evenly distributed around the central axis of the output shaft 5. This arrangement ensures that the force application area 41 and reaction force area 42 of the first swashplate 1 and the second swashplate 2 are always in contact with the torque transmission assembly 6, thus avoiding the problem of the first swashplate 1 swinging too much under the pushing force applied by the force application component 7, which would affect the use of the equipment.

[0045] In one or more embodiments, a pulley 8 is mounted on the portion of the output shaft 5 that does not extend into the receiving space 3. See also Figure 1 The pulley 8 is connected to an external servo motor 9 via a belt. The servo motor 9 can drive the output shaft 5 to rotate via the belt and pulley 8.

[0046] In one or more embodiments, the torque transmission assembly 6 includes at least: a transmission rod 61, with its two ends abutting against a first swashplate 1 and a second swashplate 2, and a first rack 611 and a second rack 612 formed on the two side surfaces of the transmission rod 61; a synchronously rotating first full gear 62 and a first half gear 63, the first half gear 63 being intermittently meshed with the first rack 611; a synchronously rotating second full gear 64 and a second half gear 65, the second half gear 65 being intermittently meshed with the second rack 612; a synchronously rotating first bevel gear 66 and a third full gear 67, the third full gear 67 being meshed with the first full gear 62 and the second full gear 64; and a meshing connection between the first bevel gear 66 and a second bevel gear 68 disposed at the shaft end of the output shaft 5.

[0047] See Figure 1 , Figure 2 When there are two sets of torque transmission components 6, the second bevel gear 68 connected to the first end of the output shaft 5 meshes with two first bevel gears 66; when there are four sets of torque transmission components 6, the second bevel gear 68 connected to the first end of the output shaft 5 meshes with four first bevel gears 66.

[0048] It should be noted that when the first half gear 63 meshes with the first rack 611, the second half gear 65 does not mesh with the second rack 612; when the second half gear 65 meshes with the second rack 612, the first half gear 63 does not mesh with the second rack 612; that is, the meshing of the first half gear 63 with the first rack 611 and the meshing of the second half gear 65 with the second rack 612 are intermittent.

[0049] See Figure 6 , Figure 7In the initial state, the second half gear 65, located at the highest point of the first swashplate 1 and the second swashplate 2, meshes with the second rack 612, while the first half gear 63 does not mesh with the first rack 611. At the lowest point of the first swashplate 1 and the second swashplate 2, the first half gear 63 meshes with the first rack 611, while the second half gear 65 does not mesh with the second rack 612.

[0050] During operation, the output shaft 5 is first controlled to rotate counterclockwise. The output shaft 5 drives the first bevel gear 66 of at least two sets of torque transmission components 6 to rotate clockwise through the second bevel gear 68. The third full gear 67 rotates clockwise synchronously with the first bevel gear 66. The third full gear 67 is meshed with the first full gear 62 and the second full gear 64. While the third full gear 67 rotates clockwise, it can drive the first full gear 62 and the second full gear 64 to rotate counterclockwise synchronously. At this time, the first full gear 62 rotates counterclockwise synchronously with the first half gear 63, and the second full gear 64 rotates counterclockwise synchronously with the second half gear 65.

[0051] See Figure 2 , Figures 5 to 7 , Figure 10 When the control output shaft 5 rotates counterclockwise, within the accommodating space 3 corresponding to the force application zone 41, the first half gear 63 and the second half gear 65 rotate counterclockwise synchronously. The second half gear 65 drives the transmission rod 61 to move relatively to the left through the second rack 612, so that the transmission rod 61, located at the highest point of the first swashplate 1 and the second swashplate 2, moves laterally to the left while rotating counterclockwise, ensuring that both ends of the transmission rod 61 always abut against the surfaces of the first swashplate 1 and the second swashplate 2. Correspondingly, within the accommodating space 3 corresponding to the reaction force zone 42, the counterclockwise rotating first half gear 63 begins to mesh with the first rack 611, and the second half gear 65 no longer meshes with the second rack 612. The first half gear 63 can drive the transmission rod 61 to move relatively to the right through the first rack 611. When the first half gear 63 and the second half gear 65 rotate 90° counterclockwise in sync, the transmission rod 61 of one set of torque transmission components 6 is located in the middle of the force application zone 41, and the transmission rod 61 of the other set of torque transmission components 6 is located in the middle of the reaction zone.

[0052] It should be noted that when the transmission rod 61 moves to the highest or lowest point of the first swashplate 1 and the second swashplate 2, it intermittently engages with the first rack 611 or the second rack 612 through the first half gear 63 and the second half gear 65, thereby enabling the transmission rod 61 to move to the left or right. The highest and lowest points of the first swashplate 1 and the second swashplate 2 are the positions where the lateral direction of the transmission rod 61 changes.

[0053] See 2. Figure 4 , Figure 10When the transmission rod 61 moves to the force application area 41 within the accommodating space 3, it receives a relatively leftward pushing force from the force application member 7. The direction of the pushing force is consistent with the direction of the transmission rod 61's movement within the force application area 41. Since the distance between the first swashplate 1 and the second swashplate 2 remains constant, the transmission rod 61 always has a tendency to move to the left. This tendency of the transmission rod 61 to move to the left is acted on the output shaft 5 through the second half gear 65, the second rack 612, the second full gear 64, the third full gear 67, the first bevel gear 66, and the second bevel gear 68. Furthermore, while the rotational speed of the output shaft 5 remains constant, the torque of the output shaft 5 is amplified. Through this arrangement, it is possible to amplify the torque of the output shaft 5 by using static external force to input mechanical energy into the output shaft 5 while the rotational speed of the output shaft 5 is kept constant under the control of the servo motor 9, thereby effectively reducing energy loss.

[0054] See Figure 2 , Figure 4 , Figure 10 When the transmission rod 61 moves to the reaction force zone 42 within the accommodating space 3, the transmission rod 61 is subjected to a rightward reaction force from the second inclined plate. The direction of the reaction force is consistent with the direction of the transmission rod 61's movement within the reaction force zone 42, ensuring that the transmission rod 61 always has a tendency to move to the right. Meanwhile, the distance between the first swashplate 1 and the second swashplate 2, and the length of the transmission rod 61 remain unchanged. This allows the rightward movement tendency of the transmission rod 61 to act on the output shaft 5 through the first half gear 63, the first rack 611, the first full gear 62, the third full gear 67, the first bevel gear 66, and the second bevel gear 68. With the output shaft 5 rotating at a constant speed, the torque of the output shaft 5 is further amplified.

[0055] In one or more embodiments, the first swashplate 1 is provided with a fixed limiting block 10 on the surface near the second swashplate 2 and the second swashplate 2 is provided with a fixed limiting block 10 on the surface away from the first swashplate 1. The limiting block 10 is used to limit the swing angle of the first swashplate 1 and the second swashplate 2.

[0056] See Figure 1 By limiting the first swashplate 1 and the second swashplate 2 with two limiting blocks 10 respectively, it can be ensured that after the force applying component 7 applies static external force in the force applying area 41, the first swashplate 1 and the second swashplate 2 can always remain in a static position, thereby improving the stability of the transmission rod 61 under the force applying area 41 and the reaction force.

[0057] In one or more embodiments, the force application member 7 includes at least an abutment rod 71, a water tank 72, and a baffle 73. The abutment rod 71 has a first end and a second end facing each other. An opening is formed on the side of the water tank 72. The top of the baffle 73 is hinged in the opening. The water tank 72 is filled with liquid through a membrane. The first end of the abutment rod 71 is hinged to the force application area 41 of the first swashplate 1, and the second end is hinged to the lower part of the baffle 73. By means of liquid pressure, the baffle 73 moves toward the first swashplate 1 to bring the first swashplate 1 to a resting position by means of the abutment rod 71.

[0058] See Figure 1 The water storage tank 72 has an opening on one side, and a baffle 73 is hinged to the top of the opening. The water storage tank 72 is filled with liquid, which can be water, through a membrane. In the initial state, under the action of atmospheric pressure, the bottom end of the baffle 73 is raised to bring the abutment rod 71 against the first swashplate 1. The force application area 41 of the first swashplate 1 is abutted by the abutment rod 71, so that the first swashplate 1 is in a stationary position. The transmission rod 61 in the accommodating space 3 relative to the force application area 41 always has a leftward pushing force applied by the force application member 7, and the transmission rod 61 relative to the reaction force area 42 always has a second force. The rightward reaction force applied by the swashplate 2; through this arrangement, the transmission rod 61 relative to the force application zone 41 always has a tendency to move to the left, and the transmission rod 61 relative to the reaction force zone 42 always has a tendency to move to the right. This tendency can indirectly act on the output shaft 5 to amplify the torque of the output shaft 5, thereby increasing the applicability of this application. At the same time, by means of atmospheric pressure acting on the water contained in the membrane, and then through the baffle 73 and the abutment rod 71, the static external force on the first swashplate 1 can be applied, which can reduce the work done by the external workpiece and reduce energy loss.

[0059] In one or more embodiments, the two ends of the transmission rod 61 are respectively rolledly connected to the first swashplate 1 and the second swashplate 2. See also Figure 2 Rollers are rotatably mounted at both ends of the transmission rod 61. The rollers make rolling contact with the first swashplate 1 and the second swashplate 2 to reduce the friction between the transmission rod 61 and the first swashplate 1 and the second swashplate 2, thereby reducing the energy loss of the transmission rod 61 when transmitting mechanical kinetic energy, improving the energy conversion of static external force applied by the force application component, and ensuring the amplification effect of the torque of the output shaft 5.

[0060] In one or more embodiments, a sleeve 11 is disposed on the output shaft 5, and the transmission rod 61 passes through the sleeve 11.

[0061] See Figure 2A sleeve 11 is connected to the output shaft 5 via a support rod, and a transmission rod 61 passes through the sleeve 11. When the output shaft 5 is rotated to cause the transmission rod 61 to rotate around the output shaft 5 and move to the left in the force application zone 41 or to the right in the reaction force zone 42, the sleeve 11 only rotates circumferentially without relative left or right movement, thus enabling the transmission rod 61 to move to the left or right within the sleeve 11. This arrangement allows the sleeve 11 to limit the transmission rod 61, preventing positional changes when the transmission rod 61 moves to the left or right, thereby preventing the first bevel gear 66 from disengaging from the second bevel gear 68, ensuring the stability of the device structure, and ensuring the stability of the torque amplification effect of the torque transmission component 6 on the output shaft 5.

[0062] In one or more embodiments, the first swashplate 1 and the second swashplate 2 are each provided with a pivot 12 along their diameter direction, and the first swashplate 1 and the second swashplate 2 swing through the pivot 12.

[0063] See Figure 1 , Figure 3 , Figure 4 A rotating shaft 12 is mounted on the surface of the first swashplate 1 away from the second swashplate 2 along the diameter of the first swashplate 1. The rotating shaft 12 is rotatably mounted on the base 13. Similarly, a rotating shaft 12 is mounted on the surface of the second swashplate 2 away from the first swashplate 1 along the diameter of the second swashplate 2. The corresponding rotating shaft 12 of the second swashplate 2 is also rotatably mounted on the base 13. This arrangement ensures the stability of the force application area 41 and reaction force area 42 of the first swashplate 1 and the second swashplate 2 during left-right swinging.

[0064] In one or more embodiments, the tilt angle between the first swashplate 1 and the second swashplate 2 is 15-45°. In one specific embodiment, the tops of the first swashplate 1 and the second swashplate 2 tilt to the right at a synchronized angle of 15°.

[0065] Example 2:

[0066] As a second embodiment of the present invention, components that are the same as or corresponding to those in the first embodiment are referred to by the same reference numerals as those in the first embodiment. The following only describes the differences between the second embodiment and the first embodiment. The difference between the second embodiment and the first embodiment lies in the structure of the force application member 7. In the second embodiment, the force application member 7 is a drive cylinder. The position of the drive cylinder is relatively fixed, and the extended shaft end of the drive cylinder is hinged to the force application area 41 of the first swashplate 1.

[0067] In the initial state, the extension shaft end of the drive cylinder extends to push the force application area 41 of the first swashplate 1 to a stationary position, causing the transmission rod 61 located in the area corresponding to the force application area 41 within the accommodating space 3 to always have a tendency to move to the left. Since the length, rotational speed, and rotational speed of the output shaft 5 do not change, the tendency of the transmission rod 61 to move to the left within the force application area 41 can be transmitted to the output shaft 5 sequentially through the second half gear 65, the second full gear 64, the third full gear 67, the first bevel gear 66, and the second bevel gear 68, thereby amplifying the torque of the output shaft 5. Correspondingly, the transmission rod 61 corresponding to the reaction force area 42 is subjected to a rightward reaction force, causing the transmission rod 61 to always have a tendency to move to the right. This tendency to move to the right is transmitted to the output shaft 5 sequentially through the first half gear 63, the first full gear 62, the third full gear 67, the first bevel gear 66, and the second bevel gear 68, further amplifying the torque of the output shaft 5.

[0068] Example 3:

[0069] As a third embodiment of the present invention, components that are the same as or corresponding to those in the first embodiment are referred to by the same reference numerals as those in the first embodiment. The following only describes the differences between the third embodiment and the first embodiment. The difference between the third embodiment and the first embodiment lies in the structure of the force application member 7. In the third embodiment, the force application member 7 is a lever 14. One end of the lever 14 is hinged to the force application area 41 of the first swashplate 1, and a weight is placed on the other end. The middle part of the lever 14 is rotatably mounted on the support member.

[0070] See Figure 11 The weight placed at the end of lever 14 can be a stone, a container of liquid, etc. Utilizing the principle of lever 14, the weight presses against one end of lever 14, and lever 14, along with the end of lever 14 hinged to the first swashplate 1, can press the force application area 41 of the first swashplate 1 to a stationary state, thereby amplifying the torque of the output shaft 5, while reducing the work done by the servo motor 9 and reducing energy loss.

[0071] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
