Description
Technical Field
[0001] This utility model belongs to the technical field of winch accessories, specifically relating to a winch clutch mechanism with remote control function. Background Technology
[0002] Clutch assemblies are common accessories on winches. They control the engagement state of the winch reducer, thus facilitating the control of rope winding and unwinding. Most existing clutch assemblies are manually controlled; the operator rotates the clutch handle, causing the clutch pin to extend or retract relative to the reducer gear ring, thereby switching the engagement state of the reducer assembly. A patent document with publication number CN111847293B discloses a winch clutch, including a gearbox and a movable gear ring rotatably connected to the gearbox. A clutch sleeve inserted into the gearbox is provided on the outer peripheral sidewall of the gearbox. The clutch sleeve has a lifting insertion hole and a clutch lever inserted into the lifting insertion hole. A push assembly is rotatably connected to the end of the clutch lever away from the gearbox, driving the clutch lever to reciprocate along the axial direction of the clutch sleeve. When the push assembly rotates to one end, the clutch lever moves towards the gearbox, fixing the movable gear ring. The existing clutches can only be manually controlled by moving the lifting and lowering column via a lever, resulting in a slow switching speed between clutch states. Some winches are often installed inside the cab, preventing the operator from directly turning the lever. The operator needs to open the cab before turning the lever, leading to slow switching speeds and cumbersome clutch control. Therefore, a winch clutch mechanism with remote control functionality is needed to overcome these difficulties. Summary of the Invention
[0003] This invention addresses the problems existing in the prior art by designing a winch clutch mechanism with remote control functionality. This invention uses a pushing device to move the lifting rod relative to the guide part, and the lifting rod drives the clutch pin to extend and retract, thereby facilitating the control of the automatic clutch operation.
[0004] The objective of this invention is achieved through the following technical solution: a winch clutch mechanism with remote control function, comprising a clutch handle seat, a clutch base threadedly connected to the bottom of the clutch handle seat; a clutch pin inserted inside the clutch base, and a plug that moves up and down synchronously with the clutch pin; an elastic element sleeved on the outer layer of the clutch pin, the elastic element being disposed between the clutch pin and the clutch base; a lifting rod mounted on the plug; a pushing device perpendicularly disposed to the clutch pin inside the clutch handle seat, the pushing device comprising a push rod body; a guide portion disposed on the push rod body, the lifting rod being fitted with the guide portion, and the lifting rod driving the clutch pin to extend and retract relative to the clutch base when the pushing device controls the extension and retraction of the push rod body.
[0005] Preferably, the clutch handle seat includes a clutch seat body and a clutch upper cover, with several fasteners securing the clutch seat body and the clutch upper cover; the pushing device further includes a power source device for driving the push rod body to extend and retract, the power source device being fixedly installed inside the clutch handle seat, and the clutch handle seat having a receiving and limiting groove for limiting the power source device; the push rod body is connected to the power source device, and the push rod body can extend and retract relative to the power source device; the lifting rod is inserted into the insert, and the end of the lifting rod has a locking nut threadedly connected to it; the clutch handle seat has paired clearance grooves extending axially along the clutch pin shaft.
[0006] Preferably, the power source device is a push rod motor, which includes a motor body and a push shaft connected to the push rod body; the outer contour of the receiving limiting groove is adapted to the outer contour of the motor body, and the outer wall of the motor body is fitted to the inner wall of the clutch handle seat; the clutch seat body is provided with a wire groove, which is located at the bottom of the receiving limiting groove; the end of the wire groove is provided with a wire hole for inserting a wire.
[0007] The clutch seat body and clutch cover are connected by fasteners, which are existing standard screws, facilitating the installation of the push device. The power source is a push rod motor, which allows for easy control of the extension and retraction of the push rod body relative to the motor body when the motor body is energized. The push rod motor is an existing standard part, and it has a stroke bar inside to control the movement position of the push rod body. The push rod motor automatically stops working when the push rod body moves to the correct position. The stroke bar is not shown in the attached drawings of the instruction manual. The lifting rod is connected to the plug through a locking nut, and the plug is fixedly connected to the clutch pin shaft. This allows the clutch pin shaft to move synchronously when the lifting rod moves axially along the relief groove.
[0008] The motor body is easily installed and secured by a accommodating limiting groove. An electric clutch controls the operating state of the winch's reducer assembly, which includes a reducer housing and an internal gear ring. The electric clutch is mounted on the reducer housing and connected to it via a clutch base threaded together. The internal gear ring has several circular grooves for inserting a clutch pin. When the clutch pin is inserted into these grooves, the internal gear ring cannot rotate relative to the reducer housing, allowing the winch to control the drum's rotation normally. When the clutch pin disengages from the circular grooves, the reducer assembly idles. An electrical control box is installed on the winch to control the drive motor's rotation. The control box contains a control circuit board, which allows the drive motor to be controlled via a remote control. The winch, drive motor, electrical control box, and remote controller are all common components found in existing winches and are not shown in the accompanying drawings. By using wire channels and through holes, the positive and negative wires of the motor body are neatly threaded through the clutch handle seat. These wires are then electrically connected to the control circuit board via terminals, allowing the remote controller to control the extension and retraction of the motor body. When the operator presses the button on the remote controller, they can remotely control the operation of the electric clutch.
[0009] Preferably, the power source is a cylinder, which includes a cylinder body and a piston rod connected to the push rod body. Here, the power source can also use the cylinder body to push the push rod body to extend or retract. The extension / retraction stroke of the cylinder body can be adjusted during initial setup, thus facilitating control of the push rod body's extension / retraction distance. The cylinder body's lead wire passes directly from the rear of the clutch handle seat and connects to a solenoid valve. The solenoid valve is electrically connected to the control circuit board, so a remote control can be used to control the extension / retraction state of the cylinder body. The solenoid valve is a standard component and is not shown in the accompanying drawings.
[0010] Preferably, the plug-in includes a U-shaped connecting part, on which a lifting rod is inserted; the bottom of the U-shaped connecting part is provided with a mounting part, which is connected to a clutch pin; the bottom of the clutch seat body is provided with a limiting hole, in which the U-shaped connecting part is inserted; the outer contour of the U-shaped connecting part is adapted to the outer contour of the limiting hole.
[0011] Preferably, the clutch pin is integrally formed with the plug or can be detachably connected; the clutch pin is provided with a first step, one end of the elastic element abuts against the first step; the other end of the elastic element abuts against the inner wall of the clutch base.
[0012] The elastic element is a compression spring. By setting a first step, the elastic element is initially compressed.
[0013] Preferably, the protrusion on the lifting rod fits snugly against the U-shaped connecting part, and the end of the lifting rod is provided with a locking nut that is threadedly connected to it, with the locking nut fitting snugly against the U-shaped connecting part; a first locking pin is provided between the insert and the clutch pin to fix the two, and the top of the clutch pin is provided with an opening groove; the mounting part is disposed in the opening groove, and the first locking pin is inserted between the clutch pin and the mounting part; the clutch seat body is provided with a pair of clearance grooves, one of which is adjacent to the locking nut, and the other clearance groove is adjacent to the protrusion on the lifting rod.
[0014] By setting a limiting hole, the clutch pin and the U-shaped connection can only move up and down along the direction of the limiting hole; by setting a clearance groove, interference between the lifting rod and the clutch handle seat is avoided.
[0015] Preferably, the clutch handle seat is further provided with a horizontal limiting groove, which extends along the axial direction of the push rod body; the plug-in includes a U-shaped connecting part, and the guide part includes a horizontal guide surface and an inclined guide surface; the guide part is wedge-shaped, which facilitates the sliding of the lifting rod on the guide part; since the guide part includes an inclined guide surface, the lifting rod requires less effort to slide; the outer contour of the horizontal limiting groove is adapted to the outer contour of the push rod body; when the push rod body is in the initial retracted state, the lifting rod is on the horizontal guide surface, and when the push rod body is extended, the lifting rod moves along the horizontal guide surface to the inclined guide surface; when the push rod body is in the initial retracted state, the lower end face of the U-shaped connecting part abuts against the upper end face of the clutch base.
[0016] The electric clutch controls the operating state of the winch's reducer assembly. The reducer assembly includes a reducer housing and an internal gear ring. The electric clutch is mounted on the reducer housing and is threadedly connected to it via a clutch base. The internal gear ring has several circular grooves for the clutch pin to pass through. When the clutch pin is inserted into these grooves, the internal gear ring cannot rotate relative to the reducer housing, allowing the winch to control the drum rotation normally. When the clutch pin disengages from the circular grooves, the reducer assembly idles. The winch also includes a drive motor, and the reducer assembly contains a planetary gear assembly. The drive motor rotates the planetary gear assembly when it operates. In the default state, the motor body is in a retracted state, and the lifting rod is on a horizontal guide surface. This allows the lifting rod to move towards the clutch cover, and the elastic element is in a compressed state. At this time, the clutch pin is inserted into the circular grooves of the internal gear ring, preventing the internal gear ring from rotating relative to the reducer housing, and the electric clutch is engaged. When the motor body controls the extension of the push rod, the lifting rod moves along the horizontal guide surface to the inclined guide surface. This causes the lifting rod to control the clutch pin to rise, and the clutch pin automatically disengages from the circular groove of the internal gear ring, putting the electric clutch in the disengaged state. When the electric clutch needs to switch back from the disengaged state to the engaged state, the motor body controls the retraction of the push rod, causing the clutch pin to descend. Due to the retraction of the lifting rod, the clutch pin has vertical travel. At this time, the clutch pin does not immediately align with the circular groove of the internal gear ring; instead, it first abuts against the outer wall of the internal gear ring. The operator manually rotates the drum on the winch, which drives the planetary gear assembly in the reducer to rotate. As the planetary gear assembly rotates, the internal gear ring rotates synchronously, causing the circular groove of the internal gear ring to automatically align with the clutch pin. Under the action of the elastic element, the clutch pin engages in the circular groove of the internal gear ring, putting the electric clutch in the engaged state.
[0017] Preferably, an annular seal is provided between the clutch seat body and the clutch cover to seal both. The clutch cover has an annular limiting groove, and the annular seal is disposed within the annular limiting groove. The outer contour of the annular seal matches the outer contour of the annular limiting groove. By providing the annular seal and the annular limiting groove, the clutch handle seat gains a certain degree of waterproofing, making it suitable for a wider range of applications.
[0018] Preferably, the clutch handle seat is threadedly connected to the clutch base, and a limiting pin is provided between the clutch handle seat and the clutch base; the clutch base is provided with a plurality of evenly distributed limiting surfaces, and the limiting surfaces and the limiting pin are arranged perpendicular to each other; when the limiting pin is installed in the clutch handle seat, the end of the limiting pin abuts against the limiting surface.
[0019] By setting a limit pin and a limit surface, relative rotation between the clutch handle seat and the clutch base is prevented. When the clutch handle seat and the clutch base are threadedly connected, the limit pin is installed on the clutch handle seat so that the limit pin abuts against the limit surface. In this way, the clutch handle seat and the clutch base can remain fixed, making the use safer and more reliable.
[0020] Compared with the prior art, this utility model has the following advantages: 1. This utility model can drive the lifting rod to move by pushing the device, and the movement of the lifting rod can control the up and down movement of the clutch pin. The pushing device is a push rod motor, which can electrically control the extension and retraction of the clutch pin, making it more widely applicable. 2. The pushing device is a push rod motor, and the wire of the push rod motor runs from the clutch handle seat, which is then conveniently connected to the electrical control box assembly. The working status of the electric clutch can then be remotely controlled by a remote control. 3. The push rod body includes a guide part, which includes a horizontal guide surface and an inclined guide surface. By moving the lifting rod between the horizontal guide surface and the inclined guide surface, the extension and retraction of the clutch pin can be quickly controlled, resulting in a faster switching speed of the electric clutch.

[0037] The clutch handle seat 1 is also provided with a horizontal limiting groove 13, which extends along the axial direction of the push rod body 72; the plug 4 includes a U-shaped connecting part 41, and the guide part 73 includes a horizontal guide surface 74 and an inclined guide surface 75; the outer contour of the horizontal limiting groove 13 is adapted to the outer contour of the push rod body 72; when the push rod body 72 is in the initial retracted state, the lifting rod 6 is on the horizontal guide surface 74; when the push rod body 72 is extended, the lifting rod 6 moves along the horizontal guide surface 74 to the inclined guide surface 75; when the push rod body 72 is in the initial retracted state, the lower end face of the U-shaped connecting part 41 abuts against the upper end face of the clutch base 2.

The clutch base 2 is provided with a plurality of evenly distributed limiting surfaces 17, and the limiting surfaces 17 and the limiting pin 16 are arranged perpendicularly to each other. When the limiting pin 16 is installed in the clutch handle seat 1, the end of the limiting pin 16 abuts against the limiting surface 17.
[0038] The specific operation process of this embodiment is as follows: An electrical control box is installed on the winch, which is used to control the rotation of the drive motor. The control box contains a control circuit board, which can control the rotation of the drive motor via a remote control. Here, the winch, drive motor, electrical control box, and remote control are all common components of existing winches and are not shown in the accompanying drawings. By setting the wire groove 106 and the wire hole 107, the positive and negative wires of the motor body 71 are neatly threaded through the clutch handle seat 1. Then, the positive and negative wires of the motor body 71 are electrically connected to the control circuit board through the terminal blocks. Thus, the remote control can control the extension and retraction state of the motor body 71. When the operator presses the button on the remote control, the working state of the electric clutch can be controlled remotely.
[0039] The electric clutch is used to control the working state of the winch's reducer assembly. The reducer assembly includes a reducer housing 20 and an internal gear ring 18. The electric clutch is mounted on the reducer housing 20 and is threadedly connected to the reducer housing 20 via a clutch base 2. The internal gear ring 18 has several circular grooves 19 for inserting the clutch pin 3. When the clutch pin 3 is inserted into the circular grooves 19 of the internal gear ring 18, the internal gear ring 18 cannot rotate relative to the reducer housing 20, thus allowing the winch to control the drum rotation normally. When the clutch pin 3 disengages from the circular grooves 19 of the internal gear ring 18, the reducer assembly will be in an idling state. The winch also includes a drive motor, and the reducer assembly also contains a planetary gear assembly. When the drive motor is working, it drives the planetary gear assembly to rotate. In the default state, the motor body 71 is in the retracted state, and the lifting rod 6 is on the horizontal guide surface 74. The lifting rod 6 has a travel distance towards the clutch cover 102, and the elastic element 5 is in a compressed state. At this time, the clutch pin 3 is inserted into the circular groove 19 of the internal gear ring 18, preventing the internal gear ring 18 from rotating relative to the reducer housing 20, and the electric clutch is in the engaged state. When the motor body 71 controls the push rod body 72 to extend, the lifting rod 6 moves along the horizontal guide surface 74 to the inclined guide surface 75. This causes the lifting rod 6 to control the clutch pin 3 to rise, automatically disengaging it from the circular groove 19 of the internal gear ring 18, and the electric clutch is in the disengaged state. When the electric clutch needs to switch back from the disengaged state to the engaged state, the motor body 71 controls the push rod body 72 to retract, causing the clutch pin 3 to descend. Through the clearance provided by the lifting rod 6, the clutch pin 3 has a vertical travel distance. At this time, the clutch pin 3 will not immediately align with the circular groove 19 of the internal gear ring 18. The clutch pin 3 will first abut against the outer wall of the internal gear ring 18. The operator manually rotates the drum on the winch, which will drive the planetary gear assembly in the reducer assembly to rotate. When the planetary gear assembly rotates, the internal gear ring 18 rotates synchronously, so the circular groove 19 of the internal gear ring 18 will automatically align with the clutch pin 3. Under the action of the elastic element 5, the clutch pin 3 is engaged in the circular groove 19 of the internal gear ring 18, and the electric clutch is in the engaged state.
[0040] Example 2
[0041] like Figure 9As shown, the planetary gear assembly in this embodiment is a three-stage planetary gear reduction module 21. The reducer assembly includes a reducer housing 20, a three-stage planetary gear reduction module 21, and an internal gear ring 18. The three-stage planetary gear reduction module 21 and the internal gear ring 18 are housed inside the reducer housing 20, and the three-stage planetary gear reduction module 21 and the internal gear ring 18 mesh with each other. When the electric clutch is engaged, the three-stage planetary gear reduction module 21 rotates when the drive motor on the winch rotates; thus, the three-stage planetary gear reduction module 21 can drive the drum on the winch to rotate. The three-stage planetary gear reduction module 21 includes a first-stage planetary reduction component 211, a second-stage planetary reduction component 212, and a third-stage planetary reduction component 213, which mesh with each other for transmission. The second-stage planetary reduction component 212 meshes with the internal gear ring 18, and the third-stage planetary reduction component 213 meshes with the drum on the winch. The clutch mechanism is positioned near the second-stage planetary deceleration assembly 212.
[0042] Example 3
[0043] like Figure 10 As shown, the main structure of this embodiment is the same as that of embodiment 2, except that the installation position of the internal gear ring 18 is different from that of embodiment 2. This results in a different reduction ratio that the planetary gear assembly can be set to. The position of the clutch mechanism is also adjusted accordingly, allowing the clutch mechanism to be adapted for installation on planetary gear assemblies of different levels, thus improving its versatility. The planetary gear assembly in this embodiment is a three-stage planetary gear reduction module 21. The reducer assembly includes a reducer housing 20, the three-stage planetary gear reduction module 21, and the internal gear ring 18. The reducer housing 20 contains the three-stage planetary gear reduction module 21 and the internal gear ring 18. The three-stage planetary gear reduction module 21 includes a first-stage planetary reduction component 211, a second-stage planetary reduction component 212, and a third-stage planetary reduction component 213. The first-stage planetary reduction component 211, the second-stage planetary reduction component 212, and the third-stage planetary reduction component 213 mesh with each other for transmission. The third-stage planetary reduction component 213 meshes with the internal gear ring 18 and with the drum on the winch. The clutch mechanism is located near the third-stage planetary reduction assembly 213. When the electric clutch is engaged, the drive motor on the winch rotates, which drives the first-stage planetary reduction assembly 211, the second-stage planetary reduction assembly 212, and the third-stage planetary reduction assembly 213 to rotate synchronously. In this way, the planetary gear assembly drives the drum to rotate.
[0044] Example 4
[0045] like Figure 8As shown, the main structure of this embodiment is the same as that of Embodiment 1, except that the power source device differs from that of Embodiment 1. The power source device in this embodiment is a cylinder, which includes a cylinder body 76, and the piston rod of the cylinder body 76 is connected to the push rod body 72. The extension and retraction stroke of the cylinder body 76 can be adjusted during initial setup, thus facilitating control of the extension and retraction distance of the push rod body 72. The lead wire of the cylinder body 76 passes directly through the tail of the clutch handle seat 1 and is connected to a solenoid valve. The solenoid valve is electrically connected to the control circuit board, so a remote control can be used to control the extension and retraction state of the cylinder body. Here, the solenoid valve and control circuit board are existing standard parts and are not shown in the accompanying drawings.
