Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, Delevoping cartridge 100 includes box body 101, driving assembly 10 to be arranged on the one end of Delevoping cartridge 100 longitudinal direction, to engage to transmit driving force with the drive shaft 200 of electrophotographic image forming to the process component in Delevoping cartridge 100, the end of drive shaft 200 has radial projection 201.The components such as photosensitive drums, developer roll, powder feeding roller can be had in Delevoping cartridge, assembly is driven to may be provided at photosensitive drums or developer roll end and be coaxial therewith, thus receive driving force and directly drive photosensitive drums or developer roll to rotate, may be alternatively provided as the most coaxial with either member, but its axle be arranged in parallel with the axle of photosensitive drums, developer roll, assembly is driven to be rotated by other components of gear set drive after receiving driving force again.In Delevoping cartridge embodiment of the present invention, in addition to driving assembly different from Delevoping cartridge of the prior art, other structures are essentially identical, therefore below for the embodiment driving assembly, the present invention is further described below, Delevoping cartridge embodiment of the present invention can have the driving assembly in arbitrary driving Assemblies Example.
As shown in Figure 2, assembly is driven to include connector 1 and the cylindrical element 2 being coaxially disposed, the connection end of connector 1 is arranged in cylindrical element 2, free end stretches out in cylindrical element 2, being provided with radially projecting part 13, this part is provided with holding tank, copulational protuberance 11 is positioned partially in holding tank, the core of free end is provided with depression 14, remaining at least partially within depression 14 of force application apparatus 12.The connection end of connector 1 is neighbouring can arrange radially projecting projection, cylindrical element 2 can arrange the position limiting structures such as limited cover, to limit the connector 1 displacement in cylindrical element 2, also can arrange the limiting structure making connector linearly move in cylindrical element 2.Can be provided with gear, and the connecting portion being connected with other structures on the lateral wall of cylindrical element 2, in the present embodiment, connecting portion may be installed the end of photosensitive drums 3, directly to drive photosensitive drums 3 to rotate.Force device is positioned at cylindrical element 2, including being arranged on the first magnetic force piece 15 of connector 1 end and being arranged on the second magnetic force piece 21 that cylindrical element 2 diapire is neighbouring, is additionally provided with spring 22 between the second magnetic force piece 21 and cylindrical element diapire.In other embodiments, force device can be only also spring or magnetic devices, first magnetic force piece or the second magnetic force piece may also be arranged on non-metallic elastic material, as long as being provided that the pushing force making connector outside, and this pushing force can be overcome to be moved axially inward when connector is under pressure.
When Delevoping cartridge is installed to electrophotographic image forming, connector 1 protrudes outwardly to ultimate range under the effect of magnetic devices and spring 22, when the arc-shaped protrusions of connector with drive shaft 200 end abuts, promotion lower link 1 in arc-shaped protrusions 202 overcomes the active force of magnetic devices and spring 22 to move in cylindrical element 2, when depression 14 to connector 1 is relative with arc-shaped protrusions 202, connector 1 is displaced outwardly in the effect of magnetic devices and spring 22, until depression 14 engages with arc-shaped protrusions.Arc-shaped protrusions extruding force application apparatus 12, makes copulational protuberance 11 closer to drive shaft 200, and when drive shaft 200 rotates, copulational protuberance 14 engages with the radial projection 201 of drive shaft 200, and drives connector 1 to rotate, and then drives assembly to rotate.
As it is shown on figure 3, copulational protuberance 11 includes the less cervical region 112 in junction surface 111, size and is positioned at the root 113 of holding tank.Wherein root 113 is spherical, and it is spherical that holding tank is also configured as being matched therewith, the opening size of holding tank more than cervical region 112 size and less than the diameter of root, thus copulational protuberance 11 can swing around spherical centre of sphere multi-angle.The force application apparatus 12 being positioned at depression 14 can apply to make copulational protuberance 11 remain along the position that the axially projecting distance of connector is maximum to copulational protuberance 11, when the arc-shaped protrusions of driven moving axis abuts, strengthen the active force to copulational protuberance 11 further, copulational protuberance 11 is made to be close to drive shaft, with stable delivery driving force.When driving assembly to be positioned at off-position, force application apparatus 12 also can not apply active force to copulational protuberance 11, but just applies to make copulational protuberance 11 remain along the axially projecting power apart from maximum position of connector to copulational protuberance 11 when abutting with drive shaft.In other embodiments, the root 113 of copulational protuberance 11 can only one of which be set to spherical with holding tank, so that it may ensures that the multi-angle of copulational protuberance 11 swings unobstructed.The opening of holding tank is alternatively the slotted opening that width is suitable with cervical region 112, thus limits copulational protuberance 11 and can only swing along an angle.
Fig. 4 a to Fig. 4 c shows when Delevoping cartridge is dismantled in electrophotographic image forming, drives the motion of assembly relative drive shaft.nullWhen Delevoping cartridge is in operating position，Force application apparatus is extruded owing to driving shape projection 202，Copulational protuberance 11 is pressed towards drive shaft，When Delevoping cartridge along A in electrophotographic image forming take out time，The arc-shaped protrusions 202 of drive shaft 200 gradually departs from force application apparatus 12，Copulational protuberance 11 is diminished by the power pulling to drive shaft 200，When connector 1 move axially be not obstructed time，Connector 1 overcomes magnetic devices 15、21 and the active force of spring 22 move in cylindrical element 2 along direction shown in arrow B，Simultaneously engaging with projection 11 overcomes the active force of force application apparatus 12 radially outward to swing along direction C，Thus diminish along the distance that connector 1 is axially projecting，Depart from diametrically with the radial projection 201 of drive shaft 200，The free end of connector 1 arcuately projection 202 with A to movement，And then be disengaged with drive shaft 200，Then copulational protuberance 11 under the effect of force application apparatus 12 along D to recover to its initial position，Connector 1 is also extrapolated under magnetic devices and spring 22 act on.Delevoping cartridge can take out in electrophotographic image forming.When connector 1 move axially be obstructed time, rely on the swing of copulational protuberance 14 to reduce axially projecting distance, it is possible to make connector 1 move along the arc-shaped protrusions 202 of drive shaft 200 and make Delevoping cartridge disassemble in electrophotographic image forming.
For increasing the bond stability forgetting about it projection 11 with drive shaft further, Fig. 5 and Fig. 6 shows two kinds of improved procedures.As it is shown in figure 5, on the face that engages of the radial projection 201 with drive shaft at the junction surface 111 of copulational protuberance can recess 114, radial projection 201 is positioned at recess 114, thus is not easy to be disengaged with junction surface 111.As shown in Figure 6, the composition surface 115 that the radial projection 201 with drive shaft at the junction surface 111 of copulational protuberance engages is set to inclination, and incline direction is set to its far-end and tilts away from the direction of rotation driving assembly, thus operationally, radial projection 201 is applied in the power pressing to connector, is not easy to be disengaged with junction surface 111.
Fig. 7 to Fig. 9 shows several embodiments of the force application apparatus driving assembly.As it is shown in fig. 7, force application apparatus 121 can be made up of non-metallic elastic material, there is elastic deformation when abutting with drive shaft, strengthen the active force to copulational protuberance further.Force application apparatus 122 in Fig. 8 is a spring, and two ends are separately fixed on two copulational protuberances, during the extruding of driven moving axis, pulls copulational protuberance closer to drive shaft.Force application apparatus 123 in Fig. 9 is magnetic devices, magnetic force piece 116 it is also equipped with on copulational protuberance, it is maintained at the position that axially projecting distance is maximum so that engaging to break through, when by other External Force Actings, copulational protuberance swings, when external force is cancelled, magnetic devices makes copulational protuberance recover the position to axially projecting distance maximum.It is understood that the position of magnetic devices also can have been changed, as long as can stably apply to make joint break through to be maintained at the position that axially projecting distance is maximum.
