Through the cooperation of the first pin 061 with the shaft holes 0421 and 0712, the first rotating force receiving tooth 071 can be rotatably hinged to the rotating force transmitting head 04 around the first pin 061, and the first pin 061 serves as a first hinge to allow the first rotating force receiving tooth 071 to be switched between a first coupling position where it is coupled to the host drive shaft to transmit rotating force and a first decoupling position where it is decoupled from the host drive shaft. One hook of the tension spring 05 is hooked to the hanging hole 0713 and the other hook is hooked to the hanging hole provided on the holder 042. Similar to the first rotational force receiving tooth 071, the second rotational force receiving tooth 072 is hinged to the rotational force transmitting head 04 by the second pin 062, and the second pin 062 serves as a second hinge about which the second rotational force receiving tooth 072 can be switched between the second coupling position and the second disengaging position. The axial direction of the first pin 061 is parallel to the axial direction of the second pin 062.

The above-described rotational force transmitting assembly 01 can facilitate the decoupling of the rotational force receiving head 08 and the driving shaft 02, but the structure of the rotational force receiving head 08 is complicated, and it is inconvenient to assemble and miniaturize it.
Further, when the insertion direction of the process cartridge into the main body is shown by the arrow in fig. 3, i.e., the line between the first rotational force receiving tooth 071 and the second rotational force receiving tooth 072 is arranged in parallel to the insertion direction, it is easy to occur the situation shown in fig. 3, i.e., the second rotational force receiving tooth 072 is easily abutted to rotate the upper end portion thereof inward, i.e., the second rotational force receiving tooth 072 is turned from the second coupling position in a direction away from the second disengagement position, so that the entire coupling process is not easy to be carried out.

The first rotating force receiving tooth 71 is hinged into the mounting groove 521 through the matching of the first pin shaft 61 and the shaft hole 713, namely is hinged to the rotating force transmission head 5 through a hinge shaft, and can be switched between a first coupling position and a first disengagement position around the first pin shaft 61; the second rotating force receiving tooth 72 is hinged into the mounting groove 521 through the matching of the second pin shaft 62 and the shaft hole 723, namely is hinged to the rotating force transmitting head 5 through a hinge shaft, and can be switched between a second coupling position and a second disengagement position around the second pin shaft 62; the axes of the first pin 61 and the second pin 62 are parallel to each other and are both perpendicular to and out of plane with the rotation axis 001 shown in fig. 4 in space; the torsion spring 43 is secured in the mounting groove 521 by the coils 420 of the torsion spring 42 being fitted over the securing axle 43, the first torsion arm 421 of the torsion spring 42 abutting against the abutting face 7110 and the second torsion arm 422 abutting against the abutting face 7210. The fixed shaft 43 constitutes a fixing place for seating the coil 420 in the present embodiment.
On both sides of the mounting groove 521, the rotational force receiving portion 52 is formed with a first limiting portion 524 and a second limiting portion 525 protruding from the end surface 520 thereof in a direction away from the guide rod 51, and the elastic restoring force of the torsion spring 42 forces the lower end surface 7120 of the tooth root portion 712 to abut against the first limiting portion 524, so that the first rotational force receiving tooth 71 is maintained at the first coupling position, i.e. the first limiting portion 524 limits the first rotational force receiving tooth 71 to turn from the first coupling position to a direction away from the first disengagement position; the elastic restoring force of the torsion spring 42 also urges the lower end surface 7220 of the tooth root 722 against the second stopper portion 525, so that the second rotational force receiving tooth 72 is held at the second coupling position, i.e., the second stopper portion 525 restricts the second rotational force receiving tooth 72 from being turned from the second coupling position in a direction away from the second disengaging position. Further, the elastic restoring force of the torsion spring 42 also urges the rotational force receiving teeth to return from the disengaged position to the coupled position.
Referring to fig. 10 to 13, the first plane 002 is a plane having a normal parallel to the axial direction of the first pin 61, the second plane 003 is a plane having a normal perpendicular to the axial direction of the first pin 612, and the rotation axis 001 as shown in fig. 4 is an intersection of the first plane 002 and the second plane 003, i.e., the center axis of the guide rod 51 is in the first plane 002.
As shown in fig. 11, the two side surfaces of the mounting groove 521 are parallel to the first plane 002, so that when the main machine driving shaft 005 drives the rotational force transmitting head 5 to rotate around the rotational axis 001, the acting force generated by the rotational force receiving teeth abutting against the side walls of the mounting groove 512 is along the tangential direction of the rotation of the rotational force transmitting head 5, i.e. no component force parallel to the first plane 002 is generated, and the rotational force receiving teeth are effectively prevented from rotating from the coupling position to the decoupling position during the rotation process, so as to improve the coupling stability between the rotational force transmitting assembly and the main machine driving shaft.
As shown in fig. 12, when the rotational force output arm 0051 of the main machine driving shaft 005 is coupled with the rotational force receiving teeth, the axial direction of the rotational force output arm 0051 is parallel to the first plane 002, and at the same time, the projections of the coupling surfaces 710 and 720 on the second plane 003 are symmetrical with respect to the first plane 002, so that the force applied by the rotational force output arm 0051 to the rotational force receiving teeth is also tangential to the rotation of the rotational force transmitting head 5, thereby improving the coupling stability between the rotational force transmitting head 5 and the main machine driving shaft 003.
In the rotational direction of the rotational force transmitting head 5 in the operating state, which is counterclockwise in this embodiment as shown in fig. 11, as shown in fig. 9 to 11, the tooth crest portion 712 of the first rotational force receiving tooth 71 is deviated in the rotational direction of the rotational force transmitting head 5 with respect to the tooth root portion 711, and the tooth crest portion 722 of the second rotational force receiving tooth 72 is deviated in the rotational direction of the rotational force transmitting head 5 with respect to the tooth root portion 721, so as to reduce the lateral dimension of the tooth root of the rotational force receiving tooth while ensuring the structural strength of the rotational force receiving tooth, so as to miniaturize the entire rotational force receiving head.
Further, when the process cartridge is loaded into the main unit in the insertion direction 006 shown by the arrow in fig. 14, if the line 007 between the first rotational force receiving tooth 71 and the second rotational force receiving tooth 72 is angled with respect to the insertion direction 006 before the process cartridge is set in position, i.e., the line 007 is not parallel to the insertion direction 006, the process cartridge is set in position more smoothly than in the prior art; if the above-mentioned angle is so large that the entire rotational force receiving tooth is deviated from the third plane 004 before the seating, the smoothness of the seating process can be further improved. The third plane 004 is a plane passing through the rotation axis 001 and parallel to the insertion direction 006. The line 007 is defined as a line of centers of projection of the rotational force receiving teeth on the end surface 520 above the end surface 520, and in the present embodiment, since the two rotational force receiving teeth are arranged centrally symmetrically with respect to the rotational axis 001, the line 007 is also orthogonal to the rotational axis 001.
Referring to fig. 15, the fixing assembly of the deviation mechanism is fixed on the end cover 100 by the fixing column 101 provided on the end cover 100 matching with the fixing hole 214, and the position of the positioning seat 21 is positioned; the free end of the rotational force receiving head 4 passes through the through hole 102 provided on the end cap 100 so that the two rotational force receiving teeth are exposed to the outside of the case body to be coupled with the main machine driving shaft, and the magnetic pole connecting lines of the first magnet, the second magnet and the third magnet are arranged and coplanar in the radial direction of the guide rod 51.
Referring to fig. 16, the magnetic poles of the second magnet 22 and the third magnet 23 toward the end of the radial center of the rotational force transmitting head 5 are like magnetic poles, and the line between the first rotational force receiving tooth 71 and the second rotational force receiving tooth 72 is orthogonal to the line of the magnetic poles of the first magnet 24, and the end of the first magnet 24 away from the radial center of the rotational force transmitting head 5 is unlike the end of the second magnet 22 toward the radial center of the rotational force receiving head 5. When the two rotational force receiving teeth drive the axial limiting member 31 to rotate to the position shown in fig. 16 by the abutting of the transmission shaft 41 and the input arm 313, if the two rotational force receiving teeth are in the decoupled state, the two rotational force receiving teeth will be maintained at the position shown in fig. 16 under the action of the attraction force and the repulsion force between the three magnets and the limiting between the transmission shaft 41 and the input arm 313.
When the two rotational force receiving teeth are driven by the main machine driving shaft and drive the rotational force transmitting head 5 and the axial limiting member 31 to rotate 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees and 315 degrees counterclockwise relative to the position shown in fig. 16, after the two rotational force receiving teeth are in the decoupled state, the torque generated by the deviation mechanism 2 on the rotational force transmitting head 5 and the abutting action between the transmitting shaft 41 and the input arm 313 force the two rotational force receiving teeth to be located at the position shown in fig. 17, 18, 19, 20, 21, 22 and 23 relative to the axial limiting member 31.
As shown in fig. 16 to 24, the connection line of the magnetic poles of the second magnet 22, that is, the connection line of the magnetic poles of the third magnet 23 is defined as an X axis, and the X axis and the Y axis divide the rotation plane of the connection line 007 into four quadrants, and it can be inferred from the above analysis that: when the line 007 of the two rotational force receiving teeth is rotated into the first and second sectors 081, 082 as shown in fig. 24, the deviation mechanism 2 will force the line 007 to be deviated out of the first and second sectors 081, 082, where the first sector 081 is the second quadrant as shown and the second sector 082 is the fourth quadrant as shown.
Therefore, the smoothness of the process cartridge seating process can be improved by adjusting the relative positional relationship of the first sectorial region 081 to the insertion direction 006 so that the connection line 007 is located at an angle to the insertion direction 006 before seating; when the included angle is large enough to enable the two rotating force receiving teeth to be in a decoupled state and deviate from the third plane 004, the smoothness of the positioning process of the processing box can be further improved; when the angle is further large so that the two rotational force receiving teeth are in the decoupled state, the connecting line 007 is deviated from a sector 008 which has the first sector area 081 as an upper limit and the bisector of the angle arranged in parallel to the inserting direction 006, the sector 008 is a hatched area as shown in fig. 24, and the apex thereof is on the rotational axis 001, so that the smoothness of the process of dropping the process cartridge can be further improved; furthermore, the included angles between two side edges of the sector 008 and the adjacent one of two side edges of the first sector area 081 are both larger than or equal to half of the central angle of the rotating force receiving tooth, which means that the rotating force receiving tooth can deviate from the sector 008 before being in place, the smoothness of the process box in-place process is further improved, and when the central angle of the sector 008 is larger than or equal to the central angle of the rotating force receiving tooth, the in-place smoothness can be obviously improved; when the third plane 004 is arranged along the bisector of the first quadrant 081, the line 007 makes an angle of 45 degrees to 135 degrees with the insertion direction 006 when the two rotational force receiving teeth are in the decoupled state, that is, the line will be deflected into the third quadrant, that is, the first quadrant.
Wherein the central angle of the rotational force receiving tooth is defined as: the center of a circle, which is the intersection point of the rotation axis 001 and the plane of the end surface 520, is the angle between the center of the circle and two tangent lines of the contour line of the projection of the part of the rotational force receiving tooth above the end surface 520 on the end surface 520.
In addition, at least the following six modifications can be made to the structure 2 of the deviation mechanism:
(1) referring to fig. 25, in the second structure of the deviation mechanism of this embodiment, the first magnet 24 is fixed on the rotational force transmitting head 5, the second magnet 22 and the third magnet 23 are fixed on the case, and the ends of the second magnet 22 and the third magnet 23 adjacent to the radial center of the rotational force transmitting head 5 are like-named magnetic poles, the magnetic pole connecting lines of the three magnets are all arranged along the radial direction of the rotational force transmitting head 5 and are coplanar, and the magnetic pole connecting lines of the second magnet 22 and the third magnet 23 are arranged collinearly. The end of the first magnet 24 away from the radial center of the rotational force transmitting head 5 and the end of the second magnet 22 adjacent to the radial center of the rotational force transmitting head 5 are like magnetic poles, and the line connecting the two rotational force receiving teeth is collinear with the line connecting the magnetic poles of the first magnet 24, and the second quadrant is the first sector area 081, and the fourth quadrant is the second sector area 082 as shown in the figure.
(2) In contrast to the second structure, when the end of the first magnet 24 away from the radial center of the rotational force transmitting head 5 and the end of the second magnet 22 adjacent to the radial center of the rotational force transmitting head 5 are opposite magnetic poles, the first quadrant is the first sector area 081, and the second quadrant is the second sector area 082.
(3) Referring to fig. 26, the deviation mechanism of the fourth configuration of the present embodiment is different from the second configuration in that an angle between a line connecting two consecutive rotational force receiving teeth and a magnetic pole of the second magnet 22, i.e., the X axis, is 75 degrees, and as shown in the drawing, the hatched areas are a first sector area 081 and a second sector area 082, wherein the first sector area 081 is formed by rotating the second quadrant 15 degrees counterclockwise around the rotational axis 001 shown in fig. 4, and the second sector area 082 is formed by rotating the third quadrant 15 degrees counterclockwise around the rotational axis 001 shown in fig. 4.
(4) Referring to fig. 27, the deviation mechanism of the fifth configuration of the present embodiment differs from the second configuration described above in that the end of the first magnet 24 facing the radial center of the rotational force transmitting head 5 and the end of the second magnet 22 facing away from the radial center of the rotational force transmitting head 5 are unlike magnetic poles. Then the second quadrant is shown as a second sector area 081 and the fourth quadrant is shown as a second sector area 082.
The insertion direction 006 is an insertion direction of the process cartridge into the main unit in the process of being seated, and can be determined by a guide post provided on the process cartridge end cap to be fitted with a guide on the main unit.
The following illustrates how the relative positions of the first magnet 24, the second magnet 22, and the third magnet are determined during the process cartridge design process:
(1) the arrangement of the three magnets is shown in fig. 24. Firstly, determining an insertion direction 006 on the driving end cover 100 of the processing box 1, and then determining a reference coordinate system formed by an X axis and a Y axis by taking the insertion direction as an angular bisector of a second quadrant, wherein the insertion direction points to the second quadrant from a fourth quadrant; secondly, the connecting line of the magnetic poles of the second magnet 22 and the third magnet 23 is parallel to the X axis to determine the fixing positions of the second magnet 22 and the third magnet on the end cover 100, namely the position of the fixing column 101 shown in FIG. 15; then, a line 007 between the two rotation force receiving teeth is determined, and a perpendicular line to the line 007 is made, and a line of poles of the first magnet 24 is parallel to the perpendicular line to determine a fixed position of the first magnet 24 on the guide bar 51.
(2) The arrangement of the three magnets is shown in fig. 26, in which a line between two rotation force receiving teeth and a line of magnetic poles of the second magnet 22 are at a small angle of α degrees. Firstly, an insertion direction 006 is determined on the driving end cover 100 of the processing box 1, an initial coordinate system formed by an X1 axis and a Y1 axis is determined by taking the insertion direction as an angular bisector of a second quadrant, and the insertion direction is directed to the second quadrant from a fourth quadrant; secondly, rotating the initial coordinate system by 90-alpha degrees clockwise to form a reference coordinate system, wherein the coordinate axes of the reference coordinate system are X and Y, and the magnetic pole connecting line of the first magnet 24 is parallel to the X axis to determine the fixed position of the first magnet on the box body; then, a line 007 between the two rotational force receiving teeth is determined, and the line 007 is rotated counterclockwise by α degrees to obtain a parallel line parallel to the line of the poles of the second magnet 22, thereby determining the fixing positions of the second magnet 22 and the third magnet 23 on the guide bar 51.
(3) For the design scheme that an included angle of α degree exists between the connection line 007 and the insertion direction 006, after the positions of the two rotational force receiving teeth and the magnet fixed on the guide rod and the initial position of the magnet fixed on the box body are determined according to the above step (1), the rotational axis 001 is used as the rotational center line, so that the magnetic pole connection line of the magnet fixed on the box body rotates counterclockwise or clockwise (45- α) degrees, and the final position of the magnet fixed on the box body is obtained.
Second embodiment of Process Cartridge
As a description of the second embodiment of the process cartridge of the present invention, only the differences from the first embodiment of the process cartridge will be described below.
Referring to fig. 28, the deviation mechanism in this embodiment is composed of two elastic rods 80 fixed to the end cap 100 of the case body, the two elastic rods 80 being arranged in parallel; the force-bearing section 812 is clamped between two resilient bars 80.
Referring to fig. 29 and 30, the cross section of the force-bearing section 812 is a first non-circular surface, and the first non-circular surface is composed of a first circular surface 8120, and a first protrusion surface 8121 and a second protrusion surface 8122 formed by protruding from the edge of the first circular surface 8120 along the radial direction. The first projection surface 8121 and the second projection surface 8122 are arranged symmetrically with respect to the center of the first circular surface 8120. In the convex direction, the size of the first projection face 8121 is gradually reduced in a direction perpendicular to the radial direction. In the convex direction, the size of the second projection face 8122 is gradually reduced in a direction perpendicular to the radial direction.
The two elastic rods 80 are in an outward bending elastic deformation state due to the squeezing action of the force-bearing section 812, and will apply an inward squeezing reaction force to the force-bearing section 812, and the reaction force will generate a torque to the force-bearing section 812.
Referring to fig. 31, when the first rotating force receiving tooth 871 and the second rotating force receiving tooth 872 rotate the axial limiting member 831 to the position shown in fig. 31 by the abutment of the transmission shaft 841 and the input arm 8313, and when both the rotating force receiving teeth are in the decoupled state, the elastic restoring force of the elastic rod 80 generates a torque through the force receiving section 812 to force the rotating force transmitting head to rotate about the rotation axis relative to the axial limiting member 831 to the position shown in fig. 32.
It can be derived that the shaded area 0881 in FIG. 33 is the first sector and the shaded area 0882 is the second sector. The central angles of the first sector area and the second sector area are both less than 90 degrees, and the specific size is related to the structure and the size of the first non-circular surface.
Of course, the cross section of the force-bearing section can be replaced by the rhombic surface 8120 shown in fig. 34, and the above effect can also be obtained, when the rhombic surface 8120 is a square surface, the central angles of the first sector area and the second sector area reach 90 degrees.
In the present invention, when both the two rotational force receiving teeth are in the decoupled state, the deviation mechanism forces the rotational force transmitting head to rotate to the connecting line between the rotational force receiving teeth, which can form an angle with at least the insertion direction of the process cartridge into the main unit, so as to improve the smoothness of the process cartridge in-place process.
