Description

Technical Field

[0001] This invention relates to the field of electric scissors technology, and more particularly to a lithium-ion battery scissors with adaptive torque control. Background Technology

[0002] With the maturity of lithium battery technology and the widespread adoption of cordless tools, lithium-ion battery shears have become widely used in gardening, agricultural harvesting, electrical cable installation, and emergency demolition due to their portability, high energy density, and low maintenance costs. Traditional lithium-ion battery shears typically use a DC motor with gear reduction to directly drive the shear head, or a simple linkage-slider mechanism to achieve the cutting action. However, existing lithium-ion battery shears have the following problems in practical applications:

[0003] Traditional scissors have a relatively fixed transmission ratio, resulting in a constant output torque. When faced with cutting objects of varying thickness or hardness, a single torque mode is often insufficient. If the torque is set too high, it can easily cause crushing or excessive impact when cutting soft materials, resulting in high energy consumption and significant vibration. If the torque is set too low, it can cause the motor to stall, the scissors to jam, or even burn out the motor when cutting thick or hard materials.

[0004] While some high-end shears have introduced mechanical shifting or manual adjustment mechanisms to change the lever arm length, existing adjustment mechanisms mostly use mechanical limit switches or potentiometers to detect the position. These mechanisms suffer from high mechanical wear and are prone to misdetection in dusty or oily working environments (such as garden pruning), leading to inaccurate adjustments. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a torque adaptive control lithium-ion battery scissors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A torque-adaptive control lithium-ion battery scissors includes a main body with a scissor shaft mounted at its front end. A first scissor head is rotatably mounted on the scissor shaft, and a second scissor head is fixed at the front end of the main body. The first and second scissor heads cooperate to form a scissor-shaped structure. A cutting handle is connected to one end of the first scissor head located inside the main body. A mounting base is provided inside the main body, and a hydraulic mechanism for controlling the movement of the cutting handle is mounted on the mounting base. A groove is formed on the cutting handle. The hydraulic mechanism includes a lifting frame and a hydraulic lifting part for controlling the lifting of the lifting frame. Slider blocks are fixed at both ends of the lifting frame, and the sliders slide within the groove of the cutting handle. An adjustment mechanism is provided inside the main body for adjusting the position of the mounting base.

[0010] As a preferred embodiment of the present invention: the horizontal distance between the slider and the scissor axis is X. n The vertical distance between the slider and the scissor axis is Z. n The mounting base travels a distance of L. n The initial angle between the shortest path of the slider and the scissor axis and the horizontal plane in standby state is θ; when adjusting the mounting base, L is detected based on the laser component. n The value, and based on L n The value of Z is used to control the hydraulic mechanism to adjust. n The value of is given by the following formula:

[0011] Z n =tanθ×L n

[0012] P n =|Z n1 -Z n2 |

[0013] Where Z1 is the vertical distance between the slider and the scissor axis before the movement, Z2 is the vertical distance between the slider and the scissor axis after the movement, and P n It is the stroke of the hydraulic mechanism;

[0014] When the slider is at its extreme position far from the first scissor head, the horizontal distance from the scissor axis is X. j The vertical distance is Z j The shearing stroke of the hydraulic mechanism at its limit position is P. max After the mounting base is adjusted, when shearing is performed at the current position, the shearing stroke P of the hydraulic mechanism is... m for:

[0015] P m =P max -tanθ×L n .

[0016] As a preferred embodiment of the present invention: the hydraulic lifting unit includes a hydraulic pipe, one end of which extends to the bottom of the lifting frame, and a hydraulic movable rod is slidably connected to the end of the hydraulic pipe in a sealed manner. The hydraulic movable rod and the hydraulic pipe are connected by an internal spring, and the top end of the hydraulic movable rod is fixed to the lifting frame. A piston rod is slidably connected to the inner wall of the other end of the hydraulic pipe in a sealed manner. The passage between the piston rod and the hydraulic movable rod is filled with hydraulic oil, and a drive unit for controlling the movement of the piston rod is installed on the mounting base.

[0017] As a preferred embodiment of the present invention: the driving unit includes a driving motor, which is mounted on a mounting base. A hydraulic control screw is installed at the output end of the driving motor. A connecting frame is fixed at one end of the piston rod, and the hydraulic control screw is threaded to the inner wall of the connecting frame.

[0018] As a preferred embodiment of the present invention: an adjusting block is rotatably mounted on one end of the main body of the device, the adjusting block is drivenly connected to an adjusting screw, an inner support frame is fixed inside the main body of the device, the adjusting screw is rotatably mounted on the inner support frame, a screw cylinder is fixed on the top of the mounting base, and the screw cylinder is connected to the adjusting screw through a thread; a slide bar is fixed on the side of the mounting base, and a slide groove is provided inside the main body of the device, the slide bar slides in the slide groove.

[0019] As a preferred embodiment of the present invention, a planetary gear structure is installed on the inner support frame, and the adjusting block is connected to the adjusting screw through the planetary gear structure.

[0020] As a preferred embodiment of the present invention: one end of the main body of the device is fixed with an annular seat, a reference line is provided on the outer side of the annular seat, a strip groove is provided on the adjusting block, a toothed block is slidably connected in the strip groove, the toothed block and the strip groove are connected by a lever spring, a circumferentially distributed slot is opened on the inner ring wall of the annular seat near the adjusting block, the toothed block is locked in the slot based on the force of the lever spring, and a lever is fixed on one side of the toothed block.

[0021] As a preferred embodiment of the present invention, the top of the main body of the device is provided with scale lines.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. By setting up a hydraulic mechanism and an adjustment mechanism, the present invention can adjust the position of the hydraulic mechanism according to the needs, thereby changing the distance between the slider and the shear shaft, and thus changing the torque during shearing.

[0024] 2. By setting up a detection mechanism, the present invention can detect the position of the mounting seat in real time during the movement of the mounting seat, and then determine the current position of the slider, so as to control the operation of the hydraulic mechanism based on preset logic.

[0025] 3. By incorporating an elastic cylinder, this invention can prevent foreign objects from falling onto the output beam path of the laser assembly, thus avoiding false detections without interfering with the movement of the mounting base.

[0026] 4. By setting the height of the slider to be adjusted in real time according to the movement of the mounting base, this invention can ensure that the opening of the first and second scissor heads remains unchanged, thus guaranteeing safety. At the same time, it limits the range of motion of the shearing handle to a certain extent, which is beneficial for controlling the size of the main body of the device and enabling better shearing operations.

[0027] 5. By incorporating structures such as adjusting blocks and planetary gears, this invention enables the adjusting screw to rotate and the position of the mounting base to be adjusted by turning the adjusting block.

[0028] 6. This invention, by setting a toothed block and a lever, can prevent the adjusting block from rotating on its own by having the toothed block engage in the slot. The baseline provides a reference for the rotation of the adjusting block. When it is necessary to cut an object of a corresponding size, the adjusting block can be rotated to the corresponding position according to the reference. For example, if the object to be cut is large, with a diameter of about 2cm, rotating the adjusting block moves the toothed block to the corresponding 2cm baseline. At this time, the mounting base moves away from the first shear head, increasing the lever arm for smoother cutting. Conversely, if the object to be cut is small, the mounting base moves closer to the first shear head based on the adjustment of the adjusting block, reducing the stroke required for the slider and increasing the cutting speed.

Detailed Implementation

[0037] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] Example 1:

[0040] A lithium-ion battery-powered scissors with adaptive torque control, such as Figure 1-7 As shown, the device includes a main body 1, with a scissor shaft mounted at its front end. A first scissor head 3 is rotatably mounted on the scissor shaft, and a second scissor head 4 is fixed at the front end of the main body 1. The first scissor head 3 and the second scissor head 4 cooperate to form a scissor-shaped structure. One end of the first scissor head 3 located inside the main body 1 is connected to a shearing handle 9. A mounting base 14 is provided inside the main body 1, and a hydraulic mechanism for controlling the movement of the shearing handle 9 is mounted on the mounting base 14. The shearing handle 9 has a sliding groove. The hydraulic mechanism includes a lifting frame 21 and a hydraulic lifting part for controlling the lifting of the lifting frame 21. Slider blocks 31 are fixed at both ends of the lifting frame 21, and the sliders 31 slide in the sliding grooves of the shearing handle 9. An adjustment mechanism for adjusting the position of the mounting base 14 is provided inside the main body 1. When the adjustment mechanism adjusts the position of the mounting base 14, the distance from the slider 31 to the scissor shaft changes. A handle 5 is provided at the bottom of the main body 1, and a control switch for controlling the hydraulic mechanism to perform shearing operations is provided on one side of the handle 5.

[0041] By setting up a hydraulic mechanism and an adjustment mechanism, the position of the hydraulic mechanism can be adjusted according to needs, thereby changing the distance between the slider 31 and the shear shaft, and thus changing the torque during shearing.

[0042] In order to detect the position of mounting bracket 14 in real time, such as Figure 7 As shown, the main body 1 of the device is provided with a detection mechanism for detecting the position of the mounting base 14. The detection mechanism includes a laser component 30 and a reference frame 10. The reference frame 10 is fixed inside the main body 1 of the device. The laser component 30 is mounted on the mounting base 14. A standard block 29 adapted to the position of the laser component 30 is fixed on the reference frame 10. The output beam direction of the laser component 30 is towards the standard block 29. The movement adjustment direction of the mounting base 14 is parallel to the output beam path of the laser component 30.

[0043] By setting up a detection mechanism, the position of the mounting base 14 can be detected in real time during the movement of the mounting base 14, thereby determining the current position of the slider 31, so as to control the operation of the hydraulic mechanism based on preset logic.

[0044] To prevent interference; such as Figure 7 As shown, the mounting base 14 and the reference frame 10 are connected by an elastic cylinder 11, and the output beam path of the laser assembly 30 is located inside the elastic cylinder 11.

[0045] By setting the elastic cylinder 11, foreign objects can be prevented from falling into the output beam path of the laser assembly 30, thus avoiding false detection without interfering with the movement of the mounting base 14.

[0046] To facilitate real-time control of the hydraulic mechanism's movement; such as Figure 2 , Figure 5 , Figure 6 As shown, the horizontal distance of the slider 31 from the scissor axis is X. n The vertical distance between slider 31 and the scissor axis is Z. n The movement distance of mounting base 14 is L n The initial angle between the shortest path of slider 31 and scissor axis and the horizontal plane in standby state is θ; when adjusting mounting base 14, L is detected based on laser assembly 30. n The value, and based on L n The value of Z is used to control the hydraulic mechanism to adjust. n The value of is given by the following formula:

[0047] Z n =tanθ×L n

[0048] P n =|Z n1 -Z n2 |

[0049] Where Z1 is the vertical distance between slider 31 and the scissor axis before movement, Z2 is the vertical distance between slider 31 and the scissor axis after movement, and P n It is the stroke of the hydraulic mechanism;

[0050] When slider 31 is at its extreme position far from the first scissor head 3, the horizontal distance from the scissor axis is X. j The vertical distance is Z j The shearing stroke of the hydraulic mechanism at its limit position is P. max After the mounting base 14 is adjusted, when shearing is performed in the current position, the shearing stroke P of the hydraulic mechanism is... m for:

[0051] P m =P max -tanθ×L n ;

[0052] By adjusting the height of the slider 31 in real time according to the movement of the mounting base 14, the opening of the first scissor head 3 and the second scissor head 4 can remain unchanged, ensuring safety. At the same time, it limits the range of motion of the shearing handle 9 to a certain extent, which is beneficial to controlling the size of the main body 1 of the device and enabling better shearing operations.

[0053] The main body 1 of the device is equipped with a control module and a power supply module, and the hydraulic mechanism and laser assembly 30 are electrically connected to the control module and the power supply module.

[0054] To facilitate control of the movement of the lifting frame 21; such as Figure 2 , Figure 5 , Figure 6 As shown, the hydraulic lifting unit includes a hydraulic pipe 20, which has an L-shaped structure. One end of the hydraulic pipe 20 extends to the bottom of the lifting frame 21. A hydraulic movable rod 26 is slidably connected to the end of the hydraulic pipe 20. The hydraulic movable rod 26 and the hydraulic pipe 20 are connected by an inner spring 27. The top end of the hydraulic movable rod 26 is fixed to the lifting frame 21. A piston rod 28 is slidably connected to the inner wall of the other end of the hydraulic pipe 20. The passage between the piston rod 28 and the hydraulic movable rod 26 is filled with hydraulic oil. A drive unit for controlling the movement of the piston rod 28 is installed on the mounting base 14.

[0055] To facilitate control of the piston rod 28's movement; such as Figure 5 , Figure 6 As shown, the drive unit includes a drive motor 12, which is mounted on a mounting base 14. A hydraulic control screw 25 is installed at the output end of the drive motor 12. A connecting frame 24 is fixed to one end of the piston rod 28, and the hydraulic control screw 25 is threadedly connected to the inner wall of the connecting frame 24.

[0056] To facilitate adjustment of the position of mounting base 14; such as Figure 3 , Figure 4 , Figure 5As shown, an adjusting block 7 is rotatably mounted on one end of the main body 1 of the device. The adjusting block 7 is connected to an adjusting screw 19. An inner support frame 23 is fixed inside the main body 1. The adjusting screw 19 is rotatably mounted on the inner support frame 23. A screw cylinder 18 is fixed on the top of the mounting base 14. The screw cylinder 18 is connected to the adjusting screw 19 by threads. A slide bar 13 is fixed on the side of the mounting base 14. A sliding groove is provided inside the main body 1 of the device. The slide bar 13 slides in the sliding groove.

[0057] To improve adjustment speed; such as Figure 4 As shown, a planetary gear structure 22 is installed on the inner support frame 23, and the adjusting block 7 is connected to the adjusting screw 19 through the planetary gear structure 22.

[0058] By setting up structures such as the adjusting block 7 and the planetary gear structure 22, the position of the mounting base 14 can be adjusted by rotating the adjusting screw 19 through the adjusting block 7.

[0059] For ease of adjustment; such as Figure 3 As shown, one end of the main body 1 of the device is fixed with an annular seat 16, a reference line 8 is provided on the outer side of the annular seat 16, a strip groove is provided on the adjusting block 7, a toothed block 17 is slidably connected in the strip groove, the toothed block 17 and the strip groove are connected by a lever spring 15, a circumferentially distributed slot is provided on the inner ring wall of the annular seat 16 near the adjusting block 7, the toothed block 17 is locked in the slot based on the force of the lever spring 15, and a lever 6 is fixed on one side of the toothed block 17.

[0060] By setting the toothed block 17 and the lever 6, the toothed block 17 can be locked in the slot to prevent the adjusting block 7 from rotating on its own. The reference line 8 can provide a fingerprint for the rotation of the adjusting block 7. When it is necessary to cut an object of a corresponding size, the adjusting block 7 can be rotated to the corresponding position according to the fingerprint of the reference line 8. For example, if the object to be cut is large, with a diameter of about 2cm, the adjusting block 7 is rotated to move the toothed block 17 to the corresponding 2cm reference line 8. At this time, the mounting base 14 moves away from the first scissor head 3, increasing the lever arm for smoother cutting. Conversely, if the object to be cut is small, the mounting base 14 moves closer to the first scissor head 3 based on the adjustment of the adjusting block 7, reducing the stroke required for the slider 31 and increasing the cutting speed.

[0061] To facilitate the measurement of the dimensions of the object being cut; such as Figure 1 As shown, the device body 1 has a scale line 2 on its top.

[0062] For the parts not disclosed in detail in this invention, such as necessary control modules, specific control methods, signal transmission methods, power supply methods, etc., those skilled in the art can ensure the smooth implementation of the solution of this invention based on common sense, normal thinking logic and existing technology.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
