The technical scheme of the invention has the following advantages:
1. the present invention provides a transmission mechanism, comprising: the pulley block comprises at least two pulleys and a transmission rope sequentially wound around the two pulleys, the transmission rope is annularly arranged, a connecting line of the two pulleys forms a dividing line, and the dividing line divides the transmission rope into a first part and a second part; the first transmission piece is arranged on one of the first part and the second part; the second transmission piece is arranged on the other one of the first part and the second part, and at least has a first position and a second position in the length direction of the transmission rope; the driving mechanism is used for forming a magnetic field distributed in a local area; and the magnetic part is arranged on the first transmission part and extends into the area capable of forming the magnetic field.
According to the scheme, the magnetic part is stressed in a magnetic field, the magnetic part is connected to the first transmission part, power is provided for movement of the first transmission part through the magnetic field, then the transmission rope of the pulley block is driven to move through the first transmission part, and the transmission rope drives the second transmission part to move. When the magnetic poles at the two ends of the magnetic field are exchanged, the stress direction of the magnetic part is changed, so that the stress condition of the magnetic part is influenced by the change of the magnetic field, and the magnetic part can reciprocate in the magnetic field. The driving rope is arranged in an annular shape, and when the first driving piece moves in two different directions, the driving rope is driven to rotate forwards or backwards. The forward direction or the reverse direction only indicates that the motion modes of the transmission rope under two states can be regarded as rotation, the two rotation directions are one positive direction and one reverse direction, the forward direction or the reverse direction is not defined for a certain rotation state, and the two rotation modes are obtained by comparing the two rotation modes when respectively existing. And the transmission rope can be controlled to rotate in the forward direction or the reverse direction, so that the reciprocating motion is output through the second transmission piece. The first transmission piece and the second transmission piece are arranged on the first portion and the second portion respectively, so that the movement paths of the first transmission piece and the second transmission piece can have overlapping portions, the length of the whole transmission mechanism can be effectively reduced, and the occupied space of the transmission mechanism is reduced. When the power is off, the magnetic field disappears, the first transmission piece is not bound by the force of the magnetic field, and a user can freely pull the transmission mechanism.
2. The invention provides a transmission mechanism, comprising: the electromagnet comprises a first electromagnet and a second electromagnet, and the area capable of forming a magnetic field is formed between the first electromagnet and the second electromagnet.
The scheme utilizes two electromagnets, and a magnetic field for driving the first transmission piece is formed between the two electromagnets. The current flow direction in the electromagnets is controlled through a circuit, so that the magnetic poles of the two electromagnets are changed, the direction of a magnetic field is changed, the stress direction of the magnetic part on the first transmission part is changed, and the first transmission part is conveyed in a reciprocating manner in the length direction of the transmission rope.
3. According to the transmission mechanism provided by the invention, the magnetic part is an electromagnet.
The electromagnet is electrified to change the current flow direction, so that the orientation of the electromagnet pole can be changed, and the electromagnet pole is subjected to reverse acting force in the same magnetic field. When the magnetic part, the first electromagnet and the second electromagnet can change the direction of the magnetic field through circuit control, the interaction force among the magnetic part, the first electromagnet and the second electromagnet can be improved.
4. The invention provides a transmission mechanism, wherein the pulley comprises: the third pulley and the fourth pulley are fixed pulleys, a connecting line between the third pulley and the fourth pulley forms the dividing line, and the first position and the second position are located between the third pulley and the fourth pulley.
The distance between the third pulley and the fourth pulley defines the travel of the first transmission member and the second transmission member. Because first driving medium and second driving medium all set up on the driving rope, consequently first driving medium and second driving medium are synchronous motion. The third pulley limits the stroke of the first transmission piece and the second transmission piece and also limits the size of the main occupied space of the transmission mechanism.
5. The invention provides a transmission mechanism, wherein the pulley further comprises: the first pulley is arranged on the first transmission piece, the transmission rope sequentially bypasses the first pulley and the third pulley, and the first pulley and the third pulley are respectively positioned on two sides of the length direction of the transmission rope.
The transmission rope winds the first pulley, and the first pulley is arranged on the first transmission piece. On the one hand, the transmission piece can be connected with the transmission rope, so that the transmission rope can drive the first transmission piece to move. On the other hand, when the transmission rope is wound around the first pulley, the transmission rope is arranged on two sides of the first pulley. At this time, if the first transmission member moves, the two sides of the transmission rope are equivalent to the same displacement, and the two sides of the transmission rope are the same transmission rope, so that the actual pulled length of the transmission rope is twice the actual moving distance of the first transmission member. Even if the existing dish washer is provided with a mechanical structure to drive the dish washer to be automatically opened and closed, the overall volume of the dish washer is influenced because the mechanical structure occupies a larger space. The actual moving distance of the first transmission piece is enlarged in the scheme, and the size of the occupied space of the transmission mechanism can be effectively reduced. The first transmission piece is controlled by a magnetic field formed between the first electromagnet and the second electromagnet. Due to the fact that the length of the actual movement path of the first transmission piece is enlarged by two times through the pulley assembly, the distance between the first electromagnet and the second electromagnet can be shortened adaptively. Because the first transmission piece is stressed in the magnetic field, the closer to the two sides of the magnetic pole, the larger the stress is, and therefore when the first transmission piece moves to the middle part of the magnetic field, the stress is reduced. The distance between the first electromagnet and the second electromagnet is shortened, and the influence of the first transmission piece on the reduction of stress can be effectively weakened.
6. The invention provides a transmission mechanism, wherein the transmission rope comprises: one end of the first transmission rope is fixed, and the other end of the first transmission rope extends to the third pulley by winding the first pulley; and the second transmission rope is used for connecting the movable end of the first transmission rope, and the second transmission rope sequentially bypasses the third pulley and the fourth pulley.
7. The invention provides a transmission mechanism, wherein the pulley further comprises: the second pulley is arranged at the movable end of the first transmission rope, one end of the second transmission rope is fixed, and the other end of the second transmission rope is sequentially wound around the second pulley, the third pulley and the fourth pulley.
The second transmission rope is connected with the movable end of the first transmission rope, so that when the first transmission rope is controlled by the first transmission piece to move twice the actual movement distance of the first transmission piece, the second transmission rope bypasses the third pulley again, and the actual pulled length of the second transmission rope is amplified twice again. When the actual movement distance of the first transmission piece is transmitted to the second transmission piece through the first transmission rope and the second transmission rope, the actual movement distance of the second transmission piece is four times of the movement distance of the first transmission piece.
8. The transmission mechanism provided by the invention is characterized in that the transmission rope further comprises: third driving rope, fifth pulley and sixth pulley, the third driving rope is reverse correspondence with the motion state of first driving rope, the fifth pulley with the motion state of second pulley is reverse correspondence, the sixth pulley with the motion state of first pulley is reverse correspondence.
The first transmission rope and the third transmission rope are symmetrically arranged in position, and the first transmission rope and the third transmission rope are pulled to be asymmetrical in shape due to the change of the movement position of the first transmission piece. The reverse direction refers to that when the first transmission piece is positioned between the first electromagnet and the second electromagnet, and the first transmission piece moves towards the first electromagnet and the second electromagnet, the movement states of the first transmission rope and the third transmission rope are changed symmetrically.
9. The transmission mechanism further comprises a first base plate and a second base plate which are buckled to form an installation space at least used for installing the pulley block.
The first substrate and the second substrate play a role in protecting the transmission mechanism, prevent external impurities from entering and influencing the performance of the transmission mechanism, and facilitate the installation and connection of the transmission mechanism.
10. The transmission mechanism provided by the invention also comprises: the limiting sliding groove is arranged on the first base plate and/or the second base plate and used for limiting the movement path of the first transmission piece and/or the second transmission piece.
The motion path of the first transmission piece and/or the second transmission piece is limited, so that redundant shaking and vibration can be reduced, and the smoothness of the motion of the first transmission piece and the second transmission piece is improved.

Example 1
The present embodiment provides a transmission mechanism, as shown in fig. 4 and 5, including: the pulley block comprises at least two pulleys and a transmission rope sequentially wound around the two pulleys, the transmission rope is annularly arranged, a connecting line of the two pulleys forms a dividing line, and the dividing line divides the transmission rope into a first part and a second part; the first transmission piece 4 and the second transmission piece 6 are respectively arranged on the first part and the second part, and the second transmission piece 6 at least has a first position and a second position in the length direction of the transmission rope; the driving mechanism is used for forming a magnetic field distributed in a local area; and a magnetic member 41 provided on the first transmission member 4 and extending into the region where the magnetic field can be formed. The magnetic part 41 is stressed in a magnetic field, the magnetic part 41 is connected to the first transmission part 4, power is provided for the movement of the first transmission part 4 through the magnetic field, then the first transmission part 4 drives the transmission rope of the pulley block to move, and the transmission rope drives the second transmission part 6 to move. When the magnetic poles at the two ends of the magnetic field are exchanged, the stress direction of the magnetic member 41 is changed, so that the stress condition of the magnetic member 41 is influenced by the change of the magnetic field, and the magnetic member 41 can reciprocate in the magnetic field. The driving rope is arranged in an annular shape, and when the first driving piece 4 moves in two different directions, the driving rope is driven to rotate forwards or backwards. The forward direction or the reverse direction only indicates that the motion modes of the transmission rope under two states can be regarded as rotation, the two rotation directions are one positive direction and one reverse direction, the forward direction or the reverse direction is not defined for a certain rotation state, and the two rotation modes are obtained by comparing the two rotation modes when respectively existing. The transmission rope can be controlled to rotate in the forward direction or the reverse direction, so that the reciprocating motion is output through the second transmission piece 6. The first transmission piece 4 and the second transmission piece 6 are respectively arranged on the first part and the second part, so that the movement paths of the first transmission piece 4 and the second transmission piece 6 are provided with overlapping parts, the length of the whole transmission mechanism can be effectively reduced, and the size of the occupied space of the transmission mechanism is reduced. In this embodiment, the first transmission member 4 is provided on the first portion, and the second transmission member 6 is provided on the second portion. As an alternative embodiment, the first transmission member 4 is provided on the second portion and the second transmission member 6 is provided on the first portion.
As shown in fig. 1, 4, and 5, the driving mechanism includes: a first electromagnet 5 and a second electromagnet 51, the first electromagnet 5 and the second electromagnet 51 forming the region capable of forming a magnetic field therebetween. The scheme utilizes two electromagnets, and a magnetic field for driving the first transmission piece 4 is formed between the two electromagnets. The current flow direction in the electromagnets is controlled by a circuit, so that the magnetic poles of the two electromagnets are changed, the direction of the magnetic field is changed, the stress direction of the magnetic part 41 on the first transmission part 4 is changed, and the first transmission part 4 is conveyed in a reciprocating manner in the length direction of the transmission rope.
In the present embodiment, as shown in fig. 1, the movement paths of the first transmission member 4 and the second transmission member 6 are both horizontal. Because the magnetic field is used to drive the first transmission member 4 to act in the present embodiment. The force applied to the first transmission member 4 is different from place to place in the magnetic field. When the first transmission member 4 moves to a position between the first electromagnet 5 and the second electromagnet 51, the resultant force of the force applied to the first transmission member 4 becomes small, resulting in uneven speed of the actual movement of the first transmission member 4. Therefore, the horizontal movement path can effectively reduce the resistance of the first transmission piece 4 to forward movement. The driving smoothness of the driving mechanism of the embodiment is improved.
In this embodiment, as shown in fig. 2, the magnetic member 41 is an electromagnet. The electromagnet is electrified to change the current flow direction, so that the orientation of the electromagnet pole can be changed, and the electromagnet pole is subjected to reverse acting force in the same magnetic field. When the magnetic member 41, the first electromagnet 5, and the second electromagnet 51 can change the magnetic field direction through circuit control, the interaction force between the magnetic member 41 and the first electromagnet 5 and the second electromagnet 51 can be increased. As an alternative embodiment, the magnetic member 41 is made of a material having magnetic properties. Or other material that can be forced to move in a magnetic field.
In this embodiment, as shown in fig. 4 and 5, the pulley includes: the third pulley 22 and the fourth pulley 23 are fixed pulleys, a connecting line between the third pulley 22 and the fourth pulley 23 forms the dividing line, and the first position and the second position are located between the third pulley 22 and the fourth pulley 23. The distance between the third pulley 22 and the fourth pulley 23 defines the travel of the first transmission member 4 and the second transmission member 6. Because the first transmission piece 4 and the second transmission piece 6 are both arranged on the transmission rope, the first transmission piece 4 and the second transmission piece 6 move synchronously. The third pulley 22 limits the travel of the first transmission member 4 and the second transmission member 6 and also limits the amount of space that is mainly occupied by the transmission mechanism.
As shown in fig. 4 and 5, the pulley further includes: the first pulley 12 is arranged on the first transmission piece 4, the transmission rope sequentially bypasses the first pulley 12 and the third pulley 22, and the first pulley 12 and the third pulley 22 are respectively positioned on two sides of the transmission rope in the length direction. The transmission rope is wound around the first pulley 12, and the first pulley 12 is arranged on the first transmission piece 4. On the one hand, the transmission piece can be connected with the transmission rope, so that the transmission rope can drive the first transmission piece 4 to move. On the other hand, when the drive rope is wound around the first pulley 12, the drive rope is provided on both sides of the first pulley 12. At this time, if the first transmission member 4 moves, it is equivalent to that both sides of the transmission rope move equally, and both sides are the same transmission rope, so that the length of the transmission rope actually pulled is twice of the actual moving distance of the first transmission member 4. Since the first transmission member 4 is controlled by the magnetic field formed between the first electromagnet 5 and the second electromagnet 51. Due to the fact that the actual movement path length of the first transmission piece 4 is enlarged twice through the pulley assembly, the distance between the first electromagnet 5 and the second electromagnet 51 can be adaptively shortened. Because the first transmission piece 4 is stressed in the magnetic field, the closer to the two sides, the more the magnetic poles are stressed, and therefore when the first transmission piece 4 moves to the middle part of the magnetic field, the stress is reduced. Shortening the distance between the first electromagnet 5 and the second electromagnet 51 can effectively reduce the influence of the reduction in the force applied to the first transmission element 4.
In this embodiment, as shown in fig. 4 and 5, the driving rope includes: a first transmission rope 1, one end of which is fixed and the other end of which extends to the third pulley 22 by passing around the first pulley 12; and the second transmission rope 2 is used for connecting the movable end of the first transmission rope 1, and the second transmission rope 2 sequentially bypasses the third pulley 22 and the fourth pulley 23. Wherein, the pulley still includes: second pulley 13 locates the expansion end of first driving rope 1, second driving rope 2 one end is fixed through second stiff end 21, and the other end is walked around in proper order second pulley 13, third pulley 22 and fourth pulley 23, then it is fixed through third stiff end 24. The second fixing end 21 and the third fixing end 24 are fixed on the first substrate 8. The second transmission rope 2 is connected with the movable end of the first transmission rope 1, so that when the first transmission rope 1 is controlled by the first transmission piece 4 to move for twice the actual movement distance of the first transmission piece 4, the second transmission rope 2 passes around the third pulley 22 again, and the actual pulled length of the second transmission rope 2 is amplified twice again. When the actual movement distance of the first transmission member 4 is transmitted to the second transmission member 6 through the first transmission rope 1 and the second transmission rope 2, the actual movement distance of the second transmission member 6 is four times of the movement distance of the first transmission member 4. Even if the existing dish washer is provided with a mechanical structure to drive the dish washer to be automatically opened and closed, the overall volume of the dish washer is influenced because the mechanical structure occupies a larger space. The actual moving distance of the first transmission piece 4 is enlarged in the scheme, and the size of the occupied space of the transmission mechanism can be effectively reduced.
In this embodiment, as shown in fig. 4 and 5, the driving rope further includes: third driving rope 3, fifth pulley 31 and sixth pulley 32, third driving rope 3 is reverse correspondence with the motion state of first driving rope 1, fifth pulley 31 with the motion state of second pulley 13 is reverse correspondence, sixth pulley 32 with the motion state of first pulley 12 is reverse correspondence. The first transmission rope 1 and the third transmission rope 3 are symmetrically arranged in position, and the first transmission rope 1 and the third transmission rope 3 are pulled to be asymmetrical in shape due to the change of the movement position of the first transmission piece 4. The reverse direction refers to that when the first transmission piece 4 is located at the middle position between the first electromagnet 5 and the second electromagnet 51, the motion states of the first transmission rope 1 and the third transmission rope 3 are changed symmetrically when the first transmission piece 4 moves towards the first electromagnet 5 and moves towards the second electromagnet 51. As shown in fig. 4 and 5, one end of the third driving rope 3 is fixed to the first base plate 8 by a fourth fixing end 33, and the other end is pulled by the second driving rope 2 by a fifth pulley 31.
As shown in fig. 4 and 5, the first pulley 12 and the second pulley 13 tension the first driving rope 1, the tensioned first driving rope 1 is divided into two parts parallel to each other, and the first driving rope 1 is parallel to the second driving rope 2 between the third pulley 22 and the fourth pulley 23. As an alternative embodiment, the first drive line 1 between the first pulley 12 and the second pulley 13 may be arranged obliquely. Similarly, the first transmission rope 1 between the first fixed end 11 and the first pulley 12 can be also obliquely arranged.
In this embodiment, as shown in fig. 1 and fig. 2, the pulley block further includes a first base plate 8 and a second base plate 81, which are fastened together to form an installation space for installing the pulley block. The first substrate 8 and the second substrate 81 play a role of protecting the transmission mechanism, prevent external impurities from entering and affecting the performance of the transmission mechanism, and also facilitate the installation and connection of the transmission mechanism.
As shown in fig. 2 and fig. 3, the present embodiment further includes: the limiting sliding groove 82 is disposed on the first base plate 8 and/or the second base plate 81, and is used for limiting a movement path of the first transmission member 4 and/or the second transmission member 6.
