Description

Speed reducing mechanism and winding device thereof

[ technical field ] A method for producing a semiconductor device

The present invention relates to a wire winding and pulling technology, and more particularly to a speed reduction mechanism with wire winding speed control and a wire winding device thereof.

[ background of the invention ]

Fig. 1 is a schematic diagram showing the relationship between video output and input in a conference room in the prior art. In the prior art, taking the conference room 13 as an example, there are generally multimedia output devices, such as: projectors or flat panel displays, and multimedia input devices such as: a computer, a DVD player, or a portable computer, etc. Under such an application scenario, the signal input terminal of the projector 11 in fig. 1 utilizes a signal wire as a connection medium for connecting with a portable computer of a user. However, since users at different positions in the conference room can be connected to the signal wire, a long signal wire must be used.

In fig. 1, one end of the signal wire 12 is connected to the projector 11, and the other end extends to the ground through the ceiling, and the user is connected to the portable computer through the signal connector at the other end of the signal wire on the ground, so that the multimedia signal of the portable computer can be output to the projector through the signal wire 12 to project the picture. In the situation of fig. 1, the long signal wires often cause disorder of the ground wires and even cause the problem of inadvertently kicking the wires. Of course, the usage scenario of fig. 1 is not limited to the ceiling of the projector device, but the same problem can be found in other scenarios, such as when the projector is placed on a table or the flat panel display is fixed on a wall.

In order to solve the above problems, in the prior art, manufacturers of audio/video signal wire parts in conference rooms manufacture automatic wire winding devices and set on conference tables for users to use. Therefore, the user can pull one end of the signal wire from the conference table and connect the signal wire to the held computer. While this approach may solve the aforementioned problem of floor wire clutter and even sometimes inadvertent kicking of the wire, additional problems are derived.

For example: after the user finishes using the wire winder, the winding force of the wire winder is increased for the most part in order to smoothly recover the wire. Although the wire can be surely recovered into the wire winding device, when the signal wire is recovered, the closer the one end of the wire is to the wire winding device, if the user is not aware of the situation, the user is easily hit by the one end of the signal wire, or because the recovery speed is too high, the one end of the wire collides with the wire winding device to generate a loud sound to frighten the user.

Accordingly, in view of the disadvantages of the prior art, a reduction mechanism and a winding device thereof are proposed to improve the disadvantages of the prior art.

[ detailed description ] embodiments

Various exemplary embodiments may be described more fully hereinafter with reference to the accompanying drawings, in which some exemplary embodiments are shown. The inventive concept may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the inventive concept to those skilled in the art. Like numbers indicate corresponding like elements. The speed reducing mechanism and the winding device will be described with reference to the drawings by using various embodiments, which are not intended to limit the invention.

Fig. 2 is an exploded view of the reduction mechanism according to the present invention. In the present embodiment, the reduction mechanism 2 includes a housing 20, a mover 21, a rotator 22, and a damper 23. The housing 20 has a first surface 200 on which a helical track 24 is provided. The movable member 21 is disposed in the spiral track 24 and can roll along the spiral track 24. In the present embodiment, the movable element 21 is a sphere, and the material of the sphere is not particularly limited. The ball 21 of this embodiment is a ball manufactured by steel material. There is at least one opening 240 in the helical track 24. In this embodiment, the opening 240 is a partial section in the circumferential direction of the spiral track 24, and is formed as a groove-like opening penetrating the housing 20. The section of the opening 240 in the helical track 24 acts as a deceleration section for the moving member in the helical track 24. In the present embodiment, the number of the openings 240 is 4, but the number is not limited thereto. The number, the positions and the lengths of the openings are dependent on the degree of deceleration of the movable element 21, for example: time, speed, etc.

The housing 20 has a rotation shaft 201 at the center. The rotary member 22 is rotatably coupled to the shaft 201 such that the rotary member 22 can perform a rotational motion with respect to the shaft 201. In this embodiment, the rotating shaft 201 is a disc structure, but the shape is not limited to this, and a user can design the shape of the rotating member 22 according to the requirement. Please refer to fig. 2 and fig. 3A, wherein fig. 3A is a schematic view of a rotating member according to an embodiment of the present invention. The rotating member 22 has a second surface 220 opposite the first surface 200. The rotating member 22 has a central hole 221 for pivotally connecting with the shaft 201, so that the rotating member 22 rotates around the shaft 201. The rotating member 22 further includes an actuating portion 25, and the actuating portion 25 is disposed on the second surface 220 and abuts against the movable member 21, so that the movable member 21 is restrained in the actuating portion 25. In this embodiment, the actuating portion 25 is a groove structure, a part of the movable member 21 is accommodated in the groove, and when the rotating member 22 performs a rotating motion, an edge of the groove abuts against the movable member 21. When the rotary member 22 rotates relative to the housing 20, the actuator 25 drives the movable member 21 to move in the spiral track 24. It is noted that in another embodiment, the groove structure of the actuating portion 25 may also extend through the housing 20. In another embodiment, as shown in fig. 3B, the actuating portion 25a is formed by a pair of parallel protrusions, and a part of the movable member 21 is located between the parallel protrusions, and one of the protrusions abuts against the movable member 21 during the rotation motion.

Referring back to fig. 2 and 3A, the damping portion 23 is selectively disposed at a specific position of the rotating member 22, which is a specific position of the rotating member 22 corresponding to at least one deceleration section of the spiral track 22 when the rotating member 22 rotates. When the movable member 21 enters one of the deceleration sections, the damping portion 23 presses against the movable member 21 to reduce the rotation speed of the rotating member 22 relative to the housing 20. In the present embodiment, the damper portion 23 has a cantilever 231 along the circumferential direction of the rotary member 22. The damping portion 23 has a resistance elastic pad 232 at an end thereof, which is a material selected to have a high friction coefficient so that when the movable member 21 moves to a position corresponding to the resistance elastic pad 232, the movable member 21 comes into contact with the resistance elastic pad 232, and the rolling speed of the movable member 21 is reduced by the friction force between the movable member 21 and the resistance elastic pad 232. It should be noted that the purpose of the cantilever 232 is to prevent the movable member 21 from being locked due to insufficient clearance when entering the deceleration section, and by the upward swing of the cantilever 232, a space for the movable member 21 to roll is provided, so that the movable member 21 can decelerate and maintain the motion state in the deceleration section. The damper portion 23 is not limited to be provided in the circumferential direction, and may be, for example: in another embodiment, as shown in fig. 3C, the damper portion 23a has a cantilever 231a in the radial direction of the rotary member 22.

Referring to fig. 2 and fig. 4A, a lifting structure 26 is further disposed on the other side of the housing 20 opposite to the rotating element 22. In this embodiment, the lifting structure 26 is a plate-shaped structure and is disposed on the third surface 202 of the housing 20, and the third surface 202 and the first surface 200 are corresponding to each other and located at two sides of the housing 20. The lifting structure 26 has a fourth surface 260 corresponding to the third surface 202, and has at least one protrusion 261 thereon, the number of which is not limited and can be designed according to the number 240 of the openings of the spiral track 24. Each projection 261 corresponds to and penetrates the opening 240 as a deceleration section on the spiral track 24. The side of the lifting structure 26 corresponding to the fourth surface 260 has an active surface 262, and has at least one first actuating structure 263 thereon, the number of which is not limited and can be determined according to design requirements. The first detent structure 263 protrudes from the active surface 262 and has an inclined surface 264. By pushing the first actuating structure 263, the lifting structure 26 can perform a lifting motion or a lowering motion at the opposite opening 240. Furthermore, in an embodiment, an elastic restoring element S, which is a spring in this embodiment, is disposed between the fourth surface 260 of the lifting structure 26 and the third surface 202 of the housing 20 to generate the pushing force required for the descending motion. It is noted that the elastic restoring element S is not essential, and in embodiments without the elastic restoring element S, the lowering movement of the lifting structure 26 may be performed by gravity.

The speed reducing mechanism 2 further comprises a driving structure 27 connected to the lifting mechanism 26 and moving between a first state and a second state for driving the lifting mechanism 26 to perform an ascending movement or a descending movement. When the driving mechanism 27 moves from the first state to the second state, the driving mechanism 27 pushes the first actuating structure 263 to control the protrusion 261 to protrude from the opening 240, when the movable member 21 moves in the spiral track 22 to the deceleration region where the corresponding protrusion 261 protrudes, the movable member 21 is pushed by the protruding protrusion 261 to abut against the damping portion 23, so as to reduce the rotation speed of the rotational motion, and when the driving mechanism 27 returns to the first state, the protrusion 261 returns to the original position, so that the movable member 21 is out of the abutting state with the damping portion 23.

As shown in fig. 2 and fig. 4A-4B, in the present embodiment, the driving structure 27 includes a pushing element 270 and a guide rod 271. And the pushing element 270 is arranged outside the acting surface 262, so that the lifting mechanism 26 is positioned between the housing 20 and the pushing element 270, and the pushing element 270 comprises a second actuating structure 272, an extending part 273 and a buckling structure 274, wherein the second actuating structure 272 is arranged corresponding to the first actuating structure 263 and abuts against each other. In this embodiment, the second actuating structure 272 is formed by a slope 275 protruding from the surface of the pushing element 270 corresponding to the action surface 262, and the slope 264 of the first actuating structure 263 abuts against each other.

The extension 273 protrudes from one end of the pushing element 270 toward the slot 204 of the first surface 200 of the housing 20, and the snap structure 274 is connected to the end of the extension 273 protruding from the first surface 200. The guide rod 271 is accommodated in the guide groove 205 on the first surface 200 of the housing 20, and one end of the guide rod 271 is connected to the snap structure 274. In this embodiment, the first end of the guide rod 271 has a through hole 276 penetrating through the body of the guide rod 271, and the fastening structure 274 is provided to penetrate and be fastened with the guide rod 271. The second end of the guide rod 271 has a second assembly portion 277 for connecting with the pressing member 28. In this embodiment, the second combining portion 277 is an opening. In this embodiment, the first surface 200 of the housing 20 is protruded with a support 206, and the pressing element 28 has a pressing body 283 with a slot 280 therein. The pressing element 28 is disposed on the first surface 200 with the support 206 received within the channel 280. In addition, an elastic restoring element 281, in this embodiment a spring, is disposed in the slot 280, one end of which abuts against the support 206 and the other end of which abuts against the wall of the slot 280. The pressing member 28 has a first combination portion 282, which is a convex body in this embodiment, at an end thereof, and is combined with the second combination portion 277 of the guide rod 271.

The deceleration mechanism can be applied to various application situations requiring deceleration, for example, please refer to fig. 5, which is an exploded schematic view of an embodiment of the winding device of the present invention. In the present embodiment, the winding device 3 includes, in addition to the speed reducing mechanism 2 shown in fig. 2, a winding shaft 30 on which a signal wire 90 is wound, for example: audio/video signal wire, network signal wire or power signal wire, but not limited thereto. The spool body 30 is connected to the rotary member 22. A winding spring (not shown) is provided between the rotary member 22 and the rotating shaft 201 of the housing 20, for example: the spiral spring is used for accumulating the power required for rotating the rotary element 22 in a first rotating direction, namely, counterclockwise rotating direction and in a second opposite rotating direction, namely, clockwise rotating direction. The spring for winding is a well-known element of the art and will not be described in detail herein. It should be noted that, although the present embodiment is provided with two separate elements between the bobbin body 30 and the rotary member 22, in another embodiment, the bobbin body 30 may be integrally formed with the rotary member 22.

Fig. 6 is a schematic cross-sectional view of a spool according to an embodiment of the present invention. The spool body 30 is fixed by a fixing member 300, for example: a screw, and a rotary member 22. The bobbin body 30 has a first bobbin 301 and a second bobbin 302, the first bobbin 301 has a first diameter D1, the second bobbin has a second diameter D2, and the first diameter D1 is smaller than the second diameter D2. In the present embodiment, a portion of the signal wire 90 is wound around the first bobbin 301, and another portion is wound around the second bobbin 302, and a first end of the signal wire 90 is led out through the second bobbin 302, and a second end of the signal wire is led out through the first bobbin 301. The first and second terminals have signal connection interfaces respectively, wherein the signal connection interface of the first terminal is connected to the device side, for example: computer, multimedia player, etc. and the signal connecting interface of the second end is connected to the electrical base fixed on the desk, wall or floor.

Referring to fig. 5 and fig. 7, fig. 7 is a perspective view of a first swing arm according to an embodiment of the present invention. The winding device 3 further has a first swing arm 31 and a stop member 32, the first swing arm 31 is rotatably coupled to the housing 20, in this embodiment, the first swing arm 31 is coupled to the shaft seat 207 of the housing 20 through a shaft hole 310, and a spring, such as a torsion spring or a volute spiral spring, capable of generating an elastic force is disposed between the first swing arm 31 and the shaft seat 207, so that when the first swing arm 31 is forced to swing at one end, the elastic force is accumulated, and when the force is removed, a power for swinging in the opposite direction is generated. The first swing arm 31 has a first end coupled to the guide rod 271 and a second end connected to the stopper 32. In this embodiment, the first end has a pair of clamping

plates

312 and 313 with a clamping slot 311. The end of the guide rod 271 has a protrusion 278, and the end of the guide rod 271 is inserted between the clamping

plates

312 and 313, so that the protrusion 278 is combined with the clamping groove 311 on the clamping plate to generate the fixing effect. The operation effect of the first swing arm 31 will be described later.

Please refer to fig. 5 and 8, wherein fig. 8 is a perspective view of a second swing arm according to an embodiment of the present invention. The reeling device 3 further has a second swing arm 33 rotatably coupled to the housing 20. In this embodiment, the second swing arm 33 has a shaft hole 330 coupled to the shaft seat 208 of the housing 20, and a spring, such as a torsion spring or a spiral spring, capable of generating an elastic force is disposed between the second swing arm 33 and the shaft seat 208, so that when one end of the second swing arm 33 is forced to swing, the elastic force is accumulated, and when the force is removed, a reverse swing power is generated. The two ends of the second swing arm 33 respectively have a braking end 331 and a releasing end 332, and the braking end 331 abuts against the positioning body 284 of the pressing element 28 after the pressing element 28 is pressed by force, so as to position the pressing element 28 in a pressing state. After the signal wire is recovered at the releasing end 332, the signal connection interface of the signal wire is abutted to the releasing portion 332, so that the second swing arm 33 rotates counterclockwise to disengage the braking end 331 from the positioning body 284, and the pressing element 28 returns to its original position.

Next, the mode of operation of the speed reducing mechanism of the present invention will be described. Taking the application of the reeling device as an example, as shown in fig. 9A and 9B, the reeling device 3 is installed on a conference table, and the signal wire 90 has signal connection interfaces 900 and 901, in this embodiment, the signal connection interfaces 900 and 901 are HDMI connectors, but not limited thereto. In fig. 9A, the signal connection interface 901 is electrically connected to the fixed signal connector 91 on the conference table, for example: 901 is the male HDMI interface, and the fixed signal connector 91 is the female HDMI interface. In addition, it should be noted that the fixed signal connector 91 is not necessarily disposed on the conference table, for example: or on the floor or wall, depending on the requirements of use. When the user wants to use the signal wire 90, as shown in fig. 9B, which is an example of a notebook computer 92, the user pulls out the signal connection interface 900 of the signal wire and connects the signal connection interface 900 to the HDMI of the notebook computer. However, the application of the speed reducing mechanism of the present invention is not limited thereto, and it can be applied to a wire winding device in any place.

Referring to fig. 10A to 10E, when the signal connection port 900 of the signal wire 90 is not pulled out from the housing 20, the movable member 21 is at the position shown in fig. 10A, and the protrusion 261 of the lifting structure 26 does not protrude out of the opening 240 of the spiral track 24. When the user pulls the signal connection interface 900 out of the housing 20, since the signal connection interface 901 is already connected to the fixed signal connector 91, the winding shaft 30 starts to rotate to drive the rotating member 22 to rotate, which is counterclockwise in this embodiment, when the signal wire 90 is pulled. After the rotating member 22 starts to rotate, the actuating portion 25 on the rotating member 22 drives the moving member 21 to rotate, and the state shown in fig. 10B is assumed. It should be noted that, during the stretching process, since the protruding portion 261 does not protrude from the spiral track 24, when the movable member 21 moves in the deceleration region (the region of the spiral track 24 where the protruding portion 261 is located), the friction resistance with the damping portion 23 is not generated by the pushing of the protruding portion 261, and thus the movement can be performed smoothly. When the signal wire 90 is stretched to a fixed position, the spool 30 does not rotate any more, and the movable member 21 stops moving, and the state shown in fig. 10C is presented.

In addition, since the spool body 30 accumulates elastic force as reverse rotation energy required for winding up the signal wire 90 during the rotation process of stretching the signal wire 90, the stop member 32 of the first swing arm 31 inside the housing 20 abuts against the signal wire 90 to generate resistance on the signal wire 90, and the signal wire 90 is prevented from being reversely rotated due to the elastic restoring force accumulated by the spool body 30 to pull back the drawn signal wire 90 during the stretching process or when the signal wire 90 is stretched to a fixed position. It should be noted that although the stop member 32 on the first swing arm 31 abuts against the signal wire 90, the signal wire 90 is pulled by an outward pulling force P during the stretching process, so that the outward pulling force pushes the first swing arm 31 to rotate counterclockwise in the stretching process of the signal wire 90, so that the first swing arm 31 is separated from the signal wire 90. Once the signal wire 90 stops pulling or is pulled to a fixed position, the first swing arm 31 rotates back to the fixed position, so that the stopper 32 abuts against the signal wire 90 again, and a resistance force for preventing the signal wire 90 from being pulled back is generated.

As shown in fig. 11A-11F, when the user does not use the signal wire 90, the user generates a pressing force F on the pressing element 28 when the signal wire 90 is drawn back to the winding device 3. At this point the pressing element 28 moves downward, pushing against the elastic restoring element 281, accumulating energy that will rebound the pressing element 28 back to the original position. After the pressing member 28 is pressed to a certain position, the braking end 331 of the second swing arm 33 abuts against the positioning body 284 on the side of the pressing member 28 by the first rotation (clockwise rotation) of the second swing arm 33 to position the pressing member 28 in the pressed state.

During the pressing of the pressing element 28, the drive structure 27 is caused to change from the first state to the second state. In the first state, since the pressing member has not been pressed yet, the guide rod 271 of the driving structure 27 stays in the state shown in fig. 10E. Once the pressing member 28 starts to move downward, one end of the pressing member 28 pushes the push rod 271 so that the push rod 271 moves downward. When the pressing member 28 is pressed to the positioning of fig. 11B, the guide rod 271 is moved downward to the second state as shown in fig. 11C. At this time, the end of the guide rod 271 pushes the first swing arm 31, so that the first swing arm 31 rotates counterclockwise, and at the same time, the stopper 32 is driven to separate from the signal wire 90, thereby removing the resistance to the signal wire 90.

Meanwhile, as shown in fig. 11D, since the guide rod 271 is also connected to the pushing element 270, when the guide rod 271 moves downward, in addition to pushing the first swing arm to rotate 31, the pushing element 270 is also driven to move in a direction, such as the X direction shown in fig. 11D. During the movement of the pushing element 270 along the X-direction, the second actuating structure 272 will also move along the X-direction. Because the second actuating structure 272 and the first actuating structure 263 abut, when the second actuating structure 272 moves along the X direction, the inclined surface 275 thereof abuts against the inclined surface 264 of the first actuating structure 263, so that the first actuating structure 263 generates the power for moving in the second direction, such as the Z direction shown in fig. 11D. When the first actuating structure 263 is pushed against the second direction, the entire lifting structure 26 is also caused to move upwards, so that 261 protrudes through the opening 240 of the helical track 24, changing the height of the helical track 24 in the region of the corresponding protrusion 261, in the Z direction. At this time, the top end of the second actuating structure 272 abuts against the first actuating structure 263, so that the first actuating structure 263 maintains a protruding state.

Since the stopper 32 of the first swing arm 31 is disengaged from the signal wire 90, the spring force accumulated in the spool 30 is released, so that the spool 30 performs a reverse rotation to take up the signal wire 90 into the housing 20. During the reverse take-up of the spool body 30, the rotary member 22 is also reversed. During the reverse rotation of the rotary member 22, the actuator 25 drives the movable member 21 again to perform the reverse movement along the spiral track 24. As shown in fig. 11E, when the movable element 21 enters the deceleration region, that is, the region corresponding to the protruding portion 261 shown in the figure, the space of the spiral track 24 is reduced due to the protruding portion 261 being protruded, so that after the movable element 21 enters the deceleration region, the movable element is ejected by the protruding portion 261 and abuts against the resistance elastic pad 232 of the damping portion 23 on the rotary element 21, and the deceleration effect is generated until the wire winding is finished. As shown in fig. 11F, after the spool body 30 retracts the signal wire 90 into the spool body 30 by the rotational motion, the signal connection interface 900 of the signal wire 90 pushes the releasing end 332 of the second swing arm 32 due to the retracting speed, so that the second swing arm 32 swings in a second direction (counterclockwise) opposite to the first direction (clockwise), and the braking end 331 leaves the positioning body 284. At this time, the restoring force of the elastic restoring member 281 pushes the pressing member 28 to move upward, thereby pulling the guide rod 271 to move back. In the process of moving the guide rod 271 back, the guide rod 271 drives the pushing element 270 to return to the original position, and at this time, because the pushing element 270 returns to the original position, the top end of the second actuating structure 272 no longer abuts against the first actuating structure 263, so that the lifting structure 260 descends, and further the protruding portion 261 is driven to descend to the state shown in fig. 10D. Finally, the signal wire 90 is completely recovered, and the state shown in fig. 9A is formed.

Through the speed reducing mechanism provided by the invention, in the rotating process, when the speed reducing mechanism rotates to a specific area, the friction force resisting the rotation is generated through the arrangement of the damping, and the rotating speed is further reduced. The area of the damping setting can be determined according to the user's needs to control where the deceleration occurs and how long the deceleration takes place. In the application of the winding mechanism, the speed of the wire rod wound in the winding process can be controlled due to the arrangement of the speed reducing mechanism, particularly the speed of the wire rod wound is reduced when the wire rod is recovered to a specific stage, so that the problem that a user is carelessly hit by one end of the wire rod or the wire rod is collided to generate sound in the recovery process or after the wire rod is recovered to the end is avoided.
