Description

Speed reduction mechanism and its winding device

The present invention is a technology for winding and drawing wire, in particular to a speed reduction mechanism with wire winding speed control and a wire winding device.

Please refer to Figure 1, which is a schematic diagram of the relationship between video output and input in a conventional conference room. In conventional technologies, 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 computers, DVD players, or portable computers. In this application scenario, the signal input end of the projector 11 in FIG. 1 will use a signal wire as a connection medium for the convenience of connecting with the user's portable computer. However, since users in different locations in the conference room can be connected to the signal cable, a long signal cable must be used.

In Figure 1, one end of the signal cable 12 is connected to the projector 11, and the other end extends through the ceiling to the ground. The user connects the signal connector at the other end of the signal cable on the ground to the portable computer, making it possible to The multimedia signal of the portable computer can be output to the projector via the signal wire 12 to project a picture. In the situation shown in Figure 1, due to the long signal wire, the ground wire is often messy, and sometimes the wire is accidentally kicked. Of course, the use situation of FIG. 1 is not limited to when the projector device is on the ceiling. In other situations, such as when the projector is placed on a table or a flat-panel display is fixed on a wall, the above-mentioned problems may also occur.

In order to solve the above-mentioned problems, in the conventional technology, the manufacturer of the audio and video signal cable part of the conference room will make an automatic winding device and set it on the conference table for users to use. In this way, the user can pull one end of the signal wire from the conference table and connect it to the computer held by it. Although this method can solve the aforementioned problem of messy ground wires, and even sometimes accidentally kicking the wires, another problem arises.

For example, after the user has finished using it, in order to be able to recycle the wire smoothly, most of this type of wire winding device will increase the force of winding the wire. Although this can ensure that the wire is recycled into the reeling device, but when the signal wire is recycled, when the end of the wire is closer to the reeling device, if you are not careful, it is easy to cause the user to be hit by the end of the signal wire, or because of the recycling speed If it is too fast, one end of the wire will hit the winding device and produce a loud noise, which will startle the user.

For this reason, in view of the lack of conventional technology, a deceleration mechanism and its winding device are proposed to improve the above-mentioned lack of conventional methods.

The present invention provides a deceleration mechanism. In the process of rotation, when the rotation reaches a specific area, through the setting of damping, friction force against rotation is generated, thereby reducing the speed of rotation. The area of the damping setting can be determined according to the needs of the user to control the location where the deceleration occurs and the length of the deceleration time.

The invention provides a wire winding mechanism. Through the setting of the deceleration mechanism, the winding speed of the wire can be controlled during the winding process, especially when the wire is recycled to a specific stage, the winding speed of the wire is reduced, so as to prevent the user from being accidentally caught by the wire. One end hits, or to avoid the problem of sound generated by the impact during or after the recovery of the wire.

Similar numbers always indicate similar components. The speed reduction mechanism and its winding device will be described below with various embodiments in conjunction with the drawings. However, the following embodiments are not intended to limit the present invention.

Please refer to FIG. 2, which is an exploded schematic diagram of the deceleration mechanism of the present invention. In this embodiment, the speed reduction mechanism 2 includes a housing 20, a moving part 21, a rotating part 22 and a damping part 23. The housing 20 has a first surface 200 on which a spiral track 24 is arranged. The movable member 21 is arranged in the spiral track 24 and can roll along the spiral track 24. In this embodiment, the moving element 21 is a sphere, and its material is not particularly limited. The ball 21 in this embodiment is a ball made of steel. There is at least one opening 240 on the spiral track 24. In this embodiment, the opening 240 is a partial segment corresponding to the circumferential direction of the spiral track 24 to form a slot-shaped opening and penetrate the housing 20. The section of the opening 240 in the spiral track 24 serves as a deceleration section of the moving part in the spiral track 24. In this embodiment, the number of openings 240 is 4, but this number is not limited. The parameters such as the number, the opening position, and the length are determined according to the degree of deceleration of the moving member 21, such as time and speed.

The housing 20 has a rotating shaft 201 in the center. The rotating member 22 is rotatably coupled with the rotating shaft 201, so that the rotating member 22 can rotate the rotating shaft 201. In this embodiment, the rotating shaft 201 is a disc structure, but it is not limited by this shape, and the user can design the shape of the rotating member 22 according to requirements. Please refer to FIG. 2 and FIG. 3A at the same time. FIG. 3A is a schematic diagram of an embodiment of the rotating member of the present invention. The rotating member 22 has a second surface 220 opposite to the first surface 200. The rotating member 22 has a shaft hole 221 in the center of the rotating member 22 to be pivotally connected to the rotating shaft 201 so that the rotating member 22 rotates with the rotating shaft 201 as the axis. The rotating member 22 further includes an actuating portion 25. The actuating portion 25 is disposed on the second surface 220 and abuts against the actuating member 21 so that the actuating member 21 is restrained in the actuating portion 25. In this embodiment, the actuating portion 25 has a groove structure, and a part of the moving element 21 is accommodated in the groove. When the rotating element 22 rotates, the edge of the groove abuts on the moving element 21. When the rotating member 22 rotates relative to the housing 20, the actuating portion 25 drives the moving member 21 to move in the spiral track 24. It should be noted that, in another embodiment, the groove structure of the actuating portion 25 can also penetrate the housing 20. In another embodiment, as shown in FIG. 3B, the actuating portion 25a is composed of a pair of parallel convex portions, and a part of the moving member 21 is located between the parallel convex portions. A convex portion abuts on the moving part 21.

Returning to FIGS. 2 and 3A, the damping part 23 is selectively disposed at a specific position of the rotating member 22. The specific position in this embodiment is that the rotating member 22 can correspond to at least one deceleration zone of the spiral track 22 when the rotating member 22 rotates. part. When the moving element 21 enters one of the deceleration sections, the damping portion 23 presses against the moving element 21 to reduce the rotation speed of the rotating element 22 relative to the housing 20. In this embodiment, the damping portion 23 has a cantilever 231 along the circumferential direction of the rotating member 22. There is a resistance elastic pad 232 at the end of the damping part 23, which can select a material with a high friction coefficient, so that when the movable member 21 moves to a position corresponding to the resistance elastic pad 232, it contacts with the resistance elastic pad 232 and penetrates the movable member 21. The friction force between 21 and the resistance elastic pad 232 reduces the rolling speed of the movable member 21. It should be noted that the purpose of the cantilever 232 is to prevent the movable member 21 from getting stuck in the deceleration section due to insufficient clearance. The upward swing of the cantilever 232 provides space for the movable member 21 to roll, so that the movable member 21 In the deceleration section, it can decelerate while maintaining the state of motion. In addition, the damping portion 23 is not limited to be disposed in the circumferential direction. For example, in another embodiment, as shown in FIG. 3C, the damping portion 23a has a cantilever 231a along the radial direction of the rotating member 22.

Please refer to FIG. 2 and FIG. 4A at the same time. On the other side of the housing 20 relative to the rotating member 22, there is a lifting structure 26. In this embodiment, the lifting structure 26 is a plate-shaped structure, which is disposed on the third surface 202 of the casing 20. The third surface 202 and the first surface 200 correspond to each other and are located on both sides of the casing. The lifting structure 26 has a fourth surface 260 corresponding to the third surface 202, and there is at least one protrusion 261 thereon, the number of which is not limited, and can be designed according to the number 240 of openings of the spiral track 24. Each protrusion 261 corresponds to and penetrates through the spiral track 24 as the opening 240 of the deceleration section. The lifting structure 26 has an action surface 262 on a side corresponding to the fourth surface 260, on which there is at least one first actuation structure 263, the number of which is not limited and can be determined according to design requirements. The first braking structure 263 protrudes from the acting surface 262 and has an inclined surface 264. By pushing the first actuation structure 263, the lifting structure 26 can perform an ascending movement or a descending movement at the opposite opening 240. In addition, in one embodiment, there is an elastic restoring element S between the fourth surface 260 of the lifting structure 26 and the third surface 202 of the housing 20. In this embodiment, a spring is used to generate the thrust required for the descending movement. It should be noted that the elastic recovery element S is not a necessary element. In the embodiment without the elastic recovery element S, the descending movement of the lifting structure 26 can be implemented by gravity.

The deceleration mechanism 2 further includes a driving structure 27 connected to the lifting mechanism 26 and moving between the first state and the second state to drive the lifting structure 26 to perform ascending or descending motion. 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 moving member 21 moves to the corresponding protrusion in the spiral track 22 In the deceleration area where the portion 261 protrudes, the movable member 21 is pushed by the protruding portion 261 and abuts against the damping portion 23, thereby reducing the rotational speed of the rotational movement. When the driving mechanism 27 returns to the first state, the protrusion portion 261 returns to the original position, so that the movable member 21 is released from the state of abutting against the damping portion 23.

As shown in FIGS. 2 and 4A-4B, in this embodiment, the driving structure 27 includes a pushing element 270 and a guide rod 271. The pushing element 270 is arranged on the outer side of the acting surface 262 so that the lifting mechanism 26 is located between the housing 20 and the pushing element 270. The pushing element 270 includes a second actuating structure 272, an extension 273 and a buckle structure 274, wherein the second The actuation structure 272 is arranged corresponding to the first actuation structure 263 and abuts against each other. In this embodiment, the second actuating structure 272 has a slope 275 protruding from the surface of the pushing element 270 corresponding to the acting surface 262 and abuts against the slope 264 of the first actuating structure 263.

The guide rod 271 is received 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 buckle structure 274. In this embodiment, the first end of the guide rod 271 is provided with a through hole 276 penetrating the body of the guide rod 271, and a buckle structure 274 is provided to pass through and be clamped together with the guide rod 271. The second end of the guide rod 271 is provided with a second combination part 277 for connecting with the pressing element 28. In this embodiment, the second combination part 277 is an opening. In this embodiment, a support body 206 protrudes from the first surface 200 of the housing 20, and the pressing element 28 has a pressing body 283 in which a groove 280 is opened. The pressing element 28 is disposed on the first surface 200, wherein the support body 206 is accommodated in the groove body 280. In addition, the groove body 280 is provided with an elastic recovery element 281. In this embodiment, it is a spring. There is a first combination portion 282 on the end of the pressing element 28, which is a convex body in this embodiment, and is combined with the second combination portion 277 on the guide rod 271.

The bobbin 30 is connected to the rotating member 22. A winding spring (not shown in the figure) is provided between the rotating member 22 and the rotating shaft 201 on the housing 20, such as a spiral spring, which is used when the rotating member 22 performs the first rotation direction. Turning clockwise is to accumulate the opposite second direction of rotation. In this embodiment, turning clockwise is the power required for turning. The spring used for winding is a well-known element to those skilled in the art, and will not be repeated here. It should be noted that, although the spool body 30 and the rotating member 22 are two separate components in this embodiment, in another embodiment, the spool body 30 and the rotating member 22 can also be implemented in an integral manner. .

As shown in FIG. 6, it is a schematic cross-sectional view of an embodiment of the bobbin body of the present invention. The bobbin body 30 is connected to the rotating member 22 through a fixing element 300, such as a screw. 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, the first diameter D1 is smaller than the second diameter D2.

The first and second ends respectively have signal connection interfaces, where the signal connection interface of the first end is connected to the device side, such as computers, multimedia players, etc., and the signal connection interface of the second end is connected to the fixed desk, On the electrical connection seat of the wall or floor.

Refer again to FIGS. 5 and 7, where FIG. 7 is a perspective view of the first embodiment of the swing arm of the present invention. The winding device 3 further has a first swing arm 31 and a stopper 32. The first swing arm 31 is rotatably connected to the housing 20. In this embodiment, the first swing arm 31 passes through the shaft hole 310 and the housing 20. The upper shaft seat 207 is coupled together, and there is a spring that can generate accumulated elastic force between the first swing arm 31 and the shaft seat 207, such as a torsion spring or a coil spring, so that the first swing arm 31 is forced to swing at one end When the time, the elastic force can be accumulated, and when the force disappears, the reverse swing power is generated. The first swing arm 31 has a first end and a second end. The first end is coupled to the guide rod 271, and the second end is connected to the stopper 32.

The action effect of the first swing arm 31 will be described later.

Please refer to FIG. 5 and FIG. 8. FIG. 8 is a perspective view of a second embodiment of the swing arm of the present invention. The winding device 3 further has a second swing arm 33 rotatably and pivotally connected to the housing 20. In this embodiment, the second swing arm 33 has a shaft hole 330 to couple with the shaft seat 208 on the housing 20, and there is a spring that can generate accumulated elastic force, such as torsion, between the second swing arm 33 and the shaft seat 208. The spring or the coil spring makes the second swing arm 33 accumulate elastic force when it swings under a force at one end, and when the force disappears, a reverse swing power is generated. Both ends of the second swing arm 33 respectively have a brake end 331 and a release end 332. The brake end 331 abuts against the positioning body 284 of the pressing element 28 after the pressing element 28 is pressed to position the pressing element 28 in the pressing position. state. The release end 332 is after the signal wire is recovered, the signal connection interface of the signal wire abuts on the release portion 332, so that the second swing arm 33 rotates counterclockwise and the brake end 331 is separated from the positioning body 284, so that the pressing element 28 returns to its original state. Bit.

Next, the mode of operation of the deceleration mechanism of the present invention will be explained. Take the wire winding device as an example. As shown in FIG. 9A and FIG. 9B, the wire winding device 3 is set 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 It is an HDMI connector, but it is not limited by this. 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 a male HDMI interface, and the fixed signal connector 91 is a female HDMI interface. In addition, it should be noted that the fixed signal connector 91 is not necessarily set on the conference table, for example, it can also be set on the floor or the wall, depending on the requirements of use. When the user wants to use the signal cable 90, as shown in the notebook computer 92 in FIG. 9B as an example, the user stretches out the signal connection interface 900 of the signal cable and connects the signal connection interface 900 to the HDMI interface of the notebook computer superior. Of course, the application of the deceleration mechanism of the present invention is not limited to this, and it can be applied to a wire winding device in any venue.

Please refer to FIGS. 10A to 10E. When the signal connection interface 900 of the signal wire 90 has not been pulled out from the housing 20, the position of the movable member 21 is as shown in FIG. 10A, and the lifting structure 26 is protruding The portion 261 has not yet protruded from the opening 240 of the spiral track 24. When the user pulls the signal connection interface 900 out of the housing 20, because the signal connection interface 901 has been connected to the fixed signal connector 91, when the signal wire 90 is stretched, the spool body 30 will start to rotate. While the rotating member 22 is driven to rotate, this embodiment rotates counterclockwise. After the rotating member 22 starts to rotate, the actuating portion 25 on the rotating member 22 will drive the rotating member 21 to follow the rotation, and the state shown in FIG. 10B is shown. It should be noted that in the process of stretching, because the protrusion 261 does not protrude from the spiral track 24, when the mover 21 moves on the deceleration area (the area with the protrusion 261 on the spiral track 24), it will not be affected. The protruding portion 261 pushes up and generates frictional resistance with the damping portion 23, so that it can move smoothly. When the signal wire 90 is stretched to the position, the spool body 30 no longer continues to rotate, and the moving member 21 stops moving, and assumes a state as shown in FIG. 10C.

In addition, since the spool body 30 accumulates the elastic force as the reverse rotation energy required for the winding during the stretching and rotation of the signal wire 90, it passes through the stopper 32 of the first swing arm 31 inside the housing 20 Leaning against the signal wire 90 can generate resistance on the signal wire 90. During the stretching process of the signal wire 90 or when it is stretched to position, the signal wire 90 is prevented from being reversed due to the elastic restoring force accumulated by the winding shaft body 30. Rotate to pull back the signal wire 90 that was pulled out. It should be noted that although the stopper 32 on the first swing arm 31 will abut the signal wire 90, because the signal wire 90 is pulled by the outward pulling force P when the signal wire 90 is stretched, the stretching process of the signal wire 90 In this case, the outward pulling force pushes the first swing arm 31 to rotate in a counterclockwise direction, 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 the position, the first swing arm 31 rotates back to position, so that the stopper 32 abuts the signal wire 90 again, which generates resistance to prevent the signal wire 90 from pulling back.

As shown in FIGS. 11A-11F, when the user does not use the signal wire 90, when the originally stretched signal wire 90 is to be retracted to the wire winding device 3, the user generates a pressing force F on the pressing element 28. At this time, the pressing element 28 moves downward, pushing the elastic recovery element 281, and accumulates the energy for the pressing element 28 to spring back to its original position in the future. After the pressing element 28 is pressed to a position, the braking end 331 of the second swing arm 33 will abut the positioning body 284 on the side of the pressing element 28 by the first turning (clockwise rotation) of the second swing arm 33. The pressing element 28 is positioned in a pressed state.

During the pressing process of the pressing element 28, the driving structure 27 will change from the first state to the second state. In the first state, since the pressing element has not yet been pressed, the guide rod 271 of the driving structure 27 stays in the state shown in FIG. 10E. Once the pressing element 28 starts to move downward, one end of the pressing element 28 pushes the push rod 271 so that the push rod 271 moves downward. When the pressing element 28 is pressed to the positioning of FIG. 11B, the guide rod 271 moves 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 also drives the stopper 32 away from the signal wire 90 to release the resistance to the signal wire 90.

At the same time, 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, it will also drive the pushing element 270 in one direction. Move in the X direction as shown in Figure 11D. When the pushing element 270 moves along the X direction, the second actuation structure 272 will also move along the X direction. Since the second actuating structure 272 and the first actuating structure 263 are abutted together, when the second actuating structure 272 moves along the X direction, the inclined surface 275 abuts against the inclined surface of the first actuating structure 263. 264, so that the first actuating structure 263 generates power to move in the second direction, as shown in the Z direction in FIG. 11D. When the first actuating structure 263 is pushed in the second direction, it also causes the entire lifting structure 26 to move upward, so that 261 protrudes from the opening 240 of the spiral track 24, and the spiral track 24 is changed in the area corresponding to the protrusion 261, The height of the track in the Z direction. At this time, the top end of the second actuation structure 272 abuts on the first actuation structure 263, so that the first actuation structure 263 maintains a protruding state.

Since the stopper 32 on the first swing arm 31 is separated from the signal wire 90, the elastic force accumulated by the spring of the spool body 30 is released, so that the spool body 30 performs a reversing and winding movement of the wire, and the signal wire 90 is gradually The retracted into the housing 20. When the spool body 30 reverses and takes up the thread, the rotating member 22 is also reversed. During the reversal of the rotating member 22, the actuating portion 25 drives the moving member 21 to move in the reverse direction along the spiral track 24 again. As shown in FIG. 11E, when the moving member 21 enters the deceleration area, that is, the area corresponding to the protrusion 261 shown in the figure, the protrusion 261 protrudes, reducing the space of the spiral track 24, so that the moving member 21 enters After the deceleration area, it is pushed out by the protrusion 261, and abuts against the elastic resistance pad 232 of the damping portion 23 on the rotating member 21, resulting in a deceleration effect until the end of the winding. As shown in FIG. 11F, when the spool body 30 retracts the signal wire 90 to the spool body 30 by rotating motion, the signal connection interface 900 of the signal wire 90 pushes against the release end of the second swing arm 32 due to the speed of the recovery. 332 causes the second swing arm 32 to swing in a second steering (counterclockwise) opposite to the first steering (clockwise), so that the braking end 331 leaves the positioning body 284. At this time, the restoring force of the elastic restoring element 281 pushes the pressing element 28 to move upward, and then pulls the guide rod 271 to move back. When the guide rod 271 moves back, the guide rod 271 drives the pushing element 270 back to the original position. At this time, because the pushing element 270 returns to the original position, the top end of the second actuating structure 272 no longer bears against the first position. The actuating structure 263 causes the lifting structure 260 to descend, thereby driving the protrusion 261 to descend back to the state shown in FIG. 10D. Finally, the recovery of the signal wire 90 is completed, and the state shown in FIG. 9A is formed.

Through the deceleration mechanism provided by the present invention, during the rotation process, when the rotation reaches a specific area, through the damping setting, friction force against rotation is generated, thereby reducing the rotation speed. The area of the damping setting can be determined according to the needs of the user to control the location where the deceleration occurs and the length of the deceleration time. In the application of the winding mechanism, because of the setting of the deceleration mechanism, the winding speed of the wire can be controlled during the winding process, especially when the wire is recycled to a specific stage, the winding speed of the wire is reduced to prevent the user from being careless.
