Description

Technical Field

[0001] This utility model relates to the field of power tool technology, and in particular to an electric shearing device. Background Technology

[0002] A traditional electric shearing device includes a movable blade and a second blade hinged to the movable blade. A drive device drives the movable blade to move, and the angle between the movable blade and the second blade changes, thereby achieving shearing.

[0003] Traditional electric shears control the start and stop of the drive unit via triggers or other operating components; however, the drive unit will not stop if the user accidentally touches the movable blade and / or the second blade, resulting in low safety. Utility Model Content

[0004] One objective of this invention is to solve or alleviate the aforementioned technical problems.

[0005] The present invention employs an electric scissor device, comprising a scissor assembly, a carrier, and an electric control device. The scissor assembly includes a movable blade and a second blade hinged to the movable blade. A drive device is driven and connected to the movable blade. The carrier is provided with an operating element that can move relative to the carrier. The electric control device is electrically connected to the drive device and can control the drive device. Both the scissor assembly and the operating element are conductive. The movable blade and / or the second blade are electrically connected to the electric control device. The electric control device is electrically connected to the operating element. Movement of the operating element triggers the electric control device. When a user simultaneously contacts both the operating element and the scissor assembly, the electric control device stops the drive device.

[0006] The effect achieved by this utility model is to prevent the user from being injured by the movable blade and the second blade when starting the electric shears, thus ensuring the user's safety.

[0007] In a further technical solution, when the user simultaneously contacts the operating component, the movable blade, and / or the second blade, the electronic control device can detect changes in at least one of the resistance, current, and voltage, and control the drive device to stop.

[0008] A further technical solution is that the electronic control device includes an input device, which includes a circuit board. The circuit board is fixedly connected to and electrically connected to the scissor assembly by a conductive screw.

[0009] This technical solution can improve the reliability of the input device.

[0010] In a further technical solution, the circuit board is a Hall plate operating component with a magnetic component that can be directly aligned with a Hall sensor.

[0011] In a further technical solution, the Hall plate is provided with a flexible conductive line electrically connected to it, and the other end of the flexible conductive line is fixedly connected to and electrically connected to the operating element.

[0012] A further technical solution involves hinged connection between the operating component and the carrier, with the two ends of the hinge point being the operating end and the rotating end, respectively, and the operating end being exposed outside the carrier.

[0013] This technical solution facilitates the use of electric shears.

[0014] A further technical solution involves a Hall plate equipped with a control Hall sensor and a reset elastic element. The two ends of the reset elastic element are connected to a carrier and an operating element, respectively, causing the magnetic element on the operating element to tend to move away from the control Hall sensor on the Hall plate.

[0015] This technical solution ensures security.

[0016] Further technical solutions also include an output device electrically connected to the main control board, which is fixed on a carrier.

[0017] A further technical solution also includes a scissor cover that is detachably fixed to the carrier and surrounds the movable blade and the second blade.

[0018] A further technical solution involves a rigid contact head at the other end of the flexible conductive wire. The conductive wire screw passes through the rigid contact head and is screwed into the operating component. The rigid contact head faces downward, causing the flexible conductive wire to extend downward first and then toward the Hall plate. The carrier is provided with a locking position for restricting the flexible conductive wire.

[0019] This technical solution ensures that the flexible conductive wires will not be interfered with.

[0020] A further technical solution involves a carrier consisting of a first carrier component and a second carrier component, which are fastened together by screws. The outer shell is fitted onto the tail end of the carrier and fixed in place. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0032] As a specific embodiment, the electric shearing device of this utility model includes a shear assembly 1, a carrier 2, an electrical control device 3, and a drive device 119. The shear assembly 1, the drive device 119, and the electrical control device 3 are disposed on the carrier 2, and a portion of the shear assembly 1 can be located outside the carrier 2. The electrical control device 3 is electrically connected to the drive device 119 and is used to control the start and stop of the drive device 119 and control the shearing rate, thereby enabling the shear assembly 1 located outside the carrier 2 to perform shearing motion.

[0033] The scissor assembly 1 includes a movable blade 11 and a second blade 12 (hinged to the scissor hinge portion 13) hinged to the movable blade 11. A drive device 119 is drivenly connected to the movable blade 11. At least one of the movable blade 11 and the second blade 12 is conductive. Conductivity means that the components can be made entirely of conductive material, partially of conductive material, or entirely non-conductive but coated with a conductive layer, etc.

[0034] The drive device 119 can be a motor, the rotation output end of which is connected to the movable blade 11 to directly drive the movable blade 11 to rotate; of course, the drive device 119 can also be indirectly driven and connected to the movable blade 11 through a gearbox-type speed change device 14.

[0035] The transmission device 14 includes a gear ring 141, a planetary gear set 142, and an output gear 1191. One end of the gear ring 141 is connected to the drive device 119, and the gear ring 141 and the drive device 119 are coaxially arranged. The other end of the gear ring 141 is connected to the scissor assembly 1. The planetary gear set 142 is located inside the gear ring 141 and meshes with the teeth inside the gear ring 141 (not shown in the figure). The output end of the drive device 119 is connected to the planetary gear set 142. One end of the output gear 1191 is connected to the planetary gear set 142, and the other end engages with the scissor assembly 1. When the drive device 119 is running, the output gear 1191 is output after being reduced in speed by the planetary gear set 142. The output gear 1191 engages with the scissor assembly 1, thereby enabling the scissor assembly 1 to perform a cutting motion.

[0036] Optionally, both ends of the gear ring 141 are provided with internal threads, so that one end of the gear ring 141 is threadedly connected to the drive device 119 and the other end is threadedly connected to the scissor assembly 1. The end of the drive device 119 is provided with motor teeth 143, which mesh with the planetary gear set 142, so that the drive device 119 can drive the planetary gear set 142 to move.

[0037] The planetary gear set 142 includes a first-stage planetary gear set 1421, a second-stage planetary gear set 1422, and a third-stage planetary gear set 1423 arranged coaxially. The motor gear 143 of the drive device 119 meshes with the first-stage planetary gear set 1421, and the output gear 1191 is connected to the third-stage planetary gear set 1423.

[0038] The primary planetary gear set 1421 includes a primary input gear 14211, a primary gear carrier 14212, and a primary output gear 14213. There are three primary input gears 14211, arranged circumferentially around the axis of the gear ring 141. Motor teeth 143 are disposed within and mesh with the three primary input gears 14211. The primary input gears 14211 mesh with the teeth inside the gear ring 141 and are located on one side of the primary gear carrier 14212. The primary output gear 14213 is located on the other side of the primary gear carrier 14212 and coincides with the axis of the gear ring 141.

[0039] The second-stage planetary gear set 1422 includes a second-stage input gear 14221, a second-stage gear carrier 14222, and a second-stage output gear 14223. There are three second-stage input gears 14221, arranged circumferentially around the axis of the gear ring 141. The first-stage output gear 14223 is disposed within the three second-stage input gears 14221 and meshes with them. The second-stage input gears 14221 mesh with the teeth inside the gear ring 141 and are disposed on one side of the second-stage gear carrier 14222. The second-stage output gear 14223 is disposed on the other side of the second-stage gear carrier 14212 and coincides with the axis of the gear ring 141.

[0040] The three-stage planetary gear set 1423 includes a three-stage input gear 14231, a three-stage gear carrier 14232, and an output gear 1191. There are four three-stage input gears 14231, arranged circumferentially around the axis of the gear ring 141. A two-stage output gear 14223 is disposed within the four three-stage input gears 14231 and meshes with them. The three-stage input gears 14231 mesh with the teeth inside the gear ring 141 and are disposed on one side of the three-stage gear carrier 14232. The output gear 1191 is disposed on the other side of the three-stage gear carrier 14232 and coincides with the axis of the gear ring 141.

[0041] Specifically, the rotational output end of the speed change device 14 is a gear 1191 with the same rotational axis as the rotational output end of the motor. One end of the movable blade 11 is provided with a driven part 111, which is a rack. The driven part 111 is provided with a positioning hole, and the movable blade 11 is provided with a slot. After the positioning pin or other positioning parts are inserted into the positioning hole and the slot, the driven part 111 and the movable blade 11 move synchronously. Of course, the driven part 111 and the movable blade 11 can also be integrally formed, or the driven part 111 and the movable blade 11 can be connected by bolts or other means. The gear 1191 meshes with the rack (the gear 1191 is a bevel tooth, and the rack is an annular fan shape, which enables the movable blade 11 to rotate around the scissor hinge part 13 as described later). The rotation of the gear 1191 drives the movable blade 11 to rotate around the scissor hinge part 13. In addition to driving the movable blade 11 to rotate, the drive device 119 can also drive the movable blade 11 to perform other forms of motion, such as translational motion, through the structure of the prior art.

[0042] The second blade 12 can be fixed relative to the carrier 2 or driven by the driving device 119 to move. It can change its position relative to the movable blade 11 and cooperate with the movable blade 11 to perform cutting. For example, the scissor assembly 1 also includes a connecting block 131. The second blade 12 is fixedly connected to the connecting block 131. One of the connecting block 131 and the second blade 12 is provided with a recess 122, and the other is provided with a protrusion 121 that cooperates with the recess 122. The protrusion 121 cooperates with the recess 122 to prevent the second blade 12 from rotating.

[0043] The connecting block 131 is connected to the gear ring 141 by threads. The end of the output gear 1191 is located inside the connecting block 131, and the connecting block 131 is provided with a clearance hole 1311 so that the toothed part of the output gear 1191 can mesh with the driven part 111 of the rack.

[0044] The carrier 2 is provided with an operating element 21 that is movable relative to the carrier 2 and is conductive. The carrier 2 may be a housing 29 or other structure used for mounting components, and is usually made of non-conductive materials such as plastic.

[0045] The operating component 21 can be linearly slidably connected to the carrier 2, such as a button or other structure that is linearly slidably connected to the carrier 2; or it can be hinged to the carrier 2, such as a trigger or other structure, as long as it can move relative to the carrier 2. The operating component 21 is made of conductive materials such as metal, or has a metal layer coated on its surface, or is conductive through other conventional conductive methods.

[0046] The electronic control device 3 is electrically connected to the operating component 21 and the scissor assembly 1; that is, the operating component 21 can be electrically connected to the scissor assembly 1 via the electronic control device 3. In addition to controlling the drive device 119, the electronic control device 3 also acts as a conductive element, allowing the operating component 21 to be electrically connected to the scissor assembly 1. The electronic control assembly 3 includes an input device 31, a power supply 32, and a main control board 39; the input device 31 and the power supply 32 are respectively electrically connected to the main control board 39.

[0047] The power supply 32 can be a secondary battery such as a lithium battery, or a power supply interface or power cord that directly or indirectly supplies power to the main control board 39 and the drive device 119. The power supply 32 is fixed on the carrier 2 and located on the side of the drive device 119 away from the scissor assembly 1. The main control board 39 and the input device 31 can both be mounted on the same circuit board, or they can be different circuit boards connected by ribbon cables. A power board 329 is fixed to the tail end of the power supply 32. The power supply 32 is equipped with a TYPE-C interface or other electrical interface to supply power to the power supply 29. The main control board 39 is fixed to the top of the carrier 2.

[0048] The drive unit 119 is electrically connected to the main control board 39, thereby enabling the main control board 39 to control the drive unit 119 to start, stop, and rotate forward and backward.

[0049] The movable blade 11 and / or the second blade 12 are electrically connected to the input device 31.

[0050] The input device 31 is electrically connected to the operating element 21.

[0051] When the operating element 21 moves, it triggers the input device 31. When the user (not shown in the attached diagram, usually their hand) simultaneously contacts the operating element 21, the movable blade 11, and / or the second blade 12, the main control board 39 controls the drive device 119 to stop. In general, when using an electric shearing device, the user contacts the operating element 21 with their hand, causing the operating element 21 to move relative to the carrier 2, thus triggering the input device 31. The input device 31 sends an electrical signal to the main control board 39, causing the drive device 119 to run. The movable blade 11 moves, changing the angle between it and the second blade 12, thereby achieving shearing. The input device 31 can be a Hall plate 311 (described later) or a circuit board equipped with sensors such as microswitches or photoelectric switches that can input electrical signals, thereby sending electrical signals to the main control board 39 in conjunction with the movement of the operating element 21.

[0052] When a user simultaneously contacts the operating component 21, the movable blade 11, and / or the second blade 12—for example, if one hand is in contact with the operating component 21 while the other hand accidentally touches the movable blade 11 and / or the second blade 12—an electrical circuit is formed by the operating component 21, the input device 31, the movable blade 11 and / or the second blade 12, and the user's body. This causes the electrical parameters of the input device 31 to change compared to the general situation of using an electric shears device. The input device 31 sends this change in electrical parameters as an electrical signal to the main control board 39 to stop the drive device 119. The main control board 39 then controls the drive device 119 to stop, and the movable blade 11 stops moving, maintaining the same angle between it and the second blade 12. This prevents the user from being injured by the movable blade 11 and the second blade 12 when starting the electric shears device, ensuring the user's safety. It is easy to understand that, compared to the general situation of using an electric shears device, this adds the feature of the user simultaneously contacting the operating component 21, the movable blade 11, and / or the second blade 12 to form an electrical circuit.

[0053] As one specific implementation, when the user simultaneously contacts the operating member 21, the movable blade 11, and / or the second blade 12, the input device 31 can detect changes in at least one of resistance, current, and voltage, and send these changes as an electrical signal to the main control board 39 to stop the drive device 119. The circuitry for the input device 31 to detect resistance, current, or voltage is prior art and will not be described in detail here.

[0054] As one specific implementation, the input device 31 detects the resistance between the operating member 21 and the exterior of the scissor assembly 1. That is, when a user simultaneously touches the operating member 21 with one hand and the scissor assembly 1 with the other hand, the user acts as a conductor. This creates a connection between the input device 31 and the exterior of the operating member 21, causing a change in resistance between them. The input device 31 then sends a signal to the control board 39, thereby controlling the drive device 119 to stop moving. It should be noted that in other embodiments, the input device 31 may also detect the current or voltage between the operating member 21 and the input device 31. Furthermore, in other embodiments, the control board 39 may directly detect a change in either resistance, current, or voltage, and then control the drive device 119 to stop.

[0055] As one specific implementation, the input device 31 includes a Hall plate 311 (it is easy to understand that at least one control Hall sensor 3111 is provided on the Hall plate 311). The Hall plate 311 is fixedly connected and electrically connected to the movable blade 11 and / or the second blade 12 by a Hall plate screw 313 with conductivity. For example, the Hall plate screw 313 passes through the Hall plate 311 and is screwed into the scissor assembly 1. The operating member 21 is provided with a magnetic element 213 that can face the control Hall sensor 3111 of the Hall plate 311. The magnetic element 213 is a magnetic... The Hall sensor 3111, used for control, can be triggered by elements such as iron. When the operating member 21 moves, the magnetic member 213 is aligned with the Hall sensor 3111, triggering the Hall plate 311. The Hall plate holder 317 and the speed change device 14 clamp the Hall plate 311, fixing it to the speed change device 14. Alternatively, the Hall plate 311 can be fixed to a connecting block 131, which is part of the scissor assembly 1. This is different from using a microswitch or similar device to contact the Hall plate 311 to receive signals. The Hall sensor 3111, which controls the Hall plate 311 by triggering it with the magnetic component 213, is non-contact. This prevents electrical signal problems caused by defects in the spring of the microswitch (such as metal wear caused by long-term operation), thereby improving the reliability of the input device 31. The Hall plate 311 can be used to trigger the operated component 21 and also allows the operated component 21 to be electrically connected to the scissor assembly 1. In addition, the Hall plate screw 313 can both fix the Hall plate 311 and serve as a conductive structure for the Hall plate 311. 11 is electrically connected to the scissor assembly 1. As one specific embodiment, the Hall plate 311 is provided with a flexible conductive wire 312 electrically connected to it. The other end of the flexible conductive wire 312 is provided with a rigid contact head 3121. The conductive wire screw 3122 passes through the rigid contact head 3121 and is screwed into the operating member 21. The rigid contact head 3121 faces downward so that the flexible conductive wire 312 extends downward first and then toward the Hall plate 311. The carrier 2 is provided with a locking position for restricting the flexible conductive wire 312 to ensure that the flexible conductive wire 312 is not interfered with.

[0056] As one specific implementation, the operating member 21 is hinged to the carrier 2, with the two ends of the hinge point being the operating end 211 and the rotating end 212, respectively. The operating end 211 is exposed outside the carrier 2. The user applies pressure or other operations to the operating end 211, causing the rotating end 212 to rotate. The magnetic member 213 is aligned with the control Hall sensor 3111 of the Hall plate 311, triggering the control Hall sensor 3111 of the Hall plate 311, thus facilitating the use of the electric shears.

[0057] Specifically, the rotating end 212 is located inside the carrier 2, and the magnetic element 213 is disposed at the rotating end 212 of the operating element 21 so that the magnetic element 213 can rotate with the rotating end 212, thereby triggering the control Hall sensor 3111 of the Hall plate 311.

[0058] As one specific implementation, the Hall plate 311 is also provided with at least two knife-edge Hall sensors 3112. The at least two knife-edge Hall sensors 3112 are arranged circumferentially around the rotation axis of the movable knife 11. The drive unit 111 may be provided with a magnet. During the rotation of the drive unit 111, it will be directly opposite the at least two knife-edge Hall sensors 3112, thereby confirming the rotation stroke of the drive unit 111.

[0059] Specifically, the Hall plate 311 is equipped with three knife-edge Hall sensors 3112, corresponding to a first knife-edge Hall sensor 31121, a second knife-edge Hall sensor 31122, and a third knife-edge Hall sensor 31123. The second knife-edge Hall sensor 31122 is located between the first knife-edge Hall sensor 31121 and the third knife-edge Hall sensor 31123, and the distance between the first knife-edge Hall sensor 31121 and the second knife-edge Hall sensor 31122 is greater than the distance between the second knife-edge Hall sensor 31122 and the third knife-edge Hall sensor 31123. When a magnet (not shown in the attached figure) fixed relative to the movable knife 11 (e.g., fixed on the movable knife 11) is directly opposite the first Hall sensor 31121, the movable knife 11 and the second knife 12 are in a closed state.

[0060] Depending on the selected gear, the magnet can move between the first blade Hall sensor 31121 and the second blade Hall sensor 31122, or between the first blade Hall sensor 31121 and the third blade Hall sensor 31123, thereby controlling the cutting opening size of the scissor assembly 1.

[0061] As one specific implementation method, the electric shear device of this utility model embodiment also includes a reset elastic member 22. The two ends of the reset elastic member 22 are respectively connected to the carrier 2 and the operating member 21, so that the magnetic member 213 on the operating member 21 tends to move away from the control Hall sensor 3111 of the Hall plate 311.

[0062] As one specific implementation, holes may be provided at positions directly opposite to the operating member 21 and the carrier 2, and the two ends of the reset elastic member 22 may be correspondingly disposed in the holes of the operating member 21 and the carrier 2, thereby enabling the positioning of the reset elastic member 22. Optionally, the reset elastic member 22 may be located on the side of the operating member 21 near the scissor assembly 1 along its rotation axis.

[0063] The drive device 119 can only drive the movable blade 11 to perform cutting when the user applies force to the operating member 21. When the user stops applying force to the operating member 21, the magnetic member 213 on the operating member 21 moves away from the control Hall sensor 3111 of the Hall plate 311 and resets, causing the drive device 119 to stop, thus ensuring safety.

[0064] As one specific implementation, the electric shearing device of this utility model embodiment further includes an output device 38 electrically connected to the main control board 39. The output device 38 is fixed on the carrier 2 and located on the upper side of the carrier 2, with a portion protruding from the carrier 2 for easy observation by the user. The output device 38 includes a display label 381, a light-blocking member 382, ​​a display panel 383, and a transparent cover 384 disposed above the display panel 383, installed sequentially from top to bottom. The main control board 39 controls the display panel 383 to output light-emitting information according to the operating state of the drive device 119. A push-button switch 319 is provided on the output device 38 to control the power supply 32.

[0065] As one specific implementation, the electric shear device of this utility model further includes a shear cover 299 that is detachably fixedly connected to the carrier 2 and surrounds the movable blade 11 and the second blade 12.

[0066] As one of the specific implementation methods, the carrier 2 is divided into a first carrier component 27 and a second carrier component 28. The first carrier component 27 and the second carrier component 28 are fastened together by screws, and the outer shell 29 is fitted onto the tail end of the carrier 2 and fixed thereon.

[0067] The terms used in this invention, such as "first," "second," etc., do not indicate any order, quantity, or importance, but are merely for distinction.

[0068] In this invention, terms such as "a" or "an" are used to indicate not a limitation on the quantity, but rather to indicate the existence of at least one of the mentioned objects.

[0069] In this utility model, terms indicating direction or location such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, and below are used to indicate relative positions rather than absolute positions.

[0070] Terms used in this invention, such as "approximately," "generally," "approximately," and "similar," are limiting terms used to indicate features that are present but allow for certain deviations. The amount of deviation allowed may vary depending on the specific context; for example, regarding dimensional deviations, the specific context may include, but is not limited to, relevant standards for dimensional tolerances.
