Description
Technical Field
The invention relates to a driving assembly, a processing box and an electronic imaging device thereof.
Background
In the related art, a process cartridge is detachably mounted on an electronic image forming apparatus. The electronic imaging device is internally provided with a driving head for outputting a rotary driving force. The process cartridge generally includes a driving assembly receiving a rotational force, a developing unit, a developer, a powder control unit, and a casing accommodating the above units, and additionally, a photosensitive unit, a charging unit, a cleaning unit, an agitating unit, and the like are additionally provided according to various kinds of process cartridge structures. The driving assembly of the processing box is arranged at one end of the processing box along the axial direction of the developing unit or the photosensitive unit, the driving assembly is meshed with a driving head in the electronic imaging device to transmit the rotating driving force to the processing box, and finally, the rotating unit (such as the developing unit, the photosensitive unit, the stirring unit and the like) in the processing box is driven to rotate to participate in the developing operation of the electronic imaging device.
Before an electrophotographic apparatus performs a developing operation (i.e., "printing" as it is often called), a user needs to mount a process cartridge into the electrophotographic apparatus, and a driving unit of the process cartridge needs to contact and engage with a driving head of the electrophotographic apparatus.
As shown in fig. 1, the process cartridge C is mounted in the electrophotographic apparatus (not shown) in a direction X1 (the direction X1 is substantially perpendicular to the axial direction of the developing unit), and the process cartridge C is supported and guided into the electrophotographic apparatus by guide rails (F11, F21) on left and right inner side plates in the electrophotographic apparatus. When the process cartridge C is mounted in the electronic imaging apparatus along the guide rails (F11, F21), as shown in fig. 2, the driving assembly 100 at one end of the process cartridge C also moves along the direction X1 to engage with the driving head 900 on the electronic imaging apparatus, since the driving head 900 is relatively fixed in the electronic imaging apparatus (can only rotate along its own axis), there is a certain probability that the rotation power receiving part 110 of the driving assembly 100 will interfere with the driving head 900 during the process that the driving assembly 100 moves along the direction X1 to engage with the driving head 900. Therefore, in the prior art, when the rotary power receiving part 110 forms a structural interference with the driving head 900, the rotary power receiving part 110 thereof is pressed from the driving head 900 to be retracted inward in the axial direction thereof to avoid the structural interference. When the rotational power receiving member 110 continues to move to be substantially coaxial with the driving head 900, the structural interference between the rotational power receiving member 110 and the driving head 900 disappears, and the rotational power receiving member 110 is outwardly extended by the elastic force of the spring provided inside the driving assembly 100 to be in contact engagement with the driving head 900.
However, when the user needs to take out the process cartridge C, since the rotational power receiving part 110 of the driving assembly 100 has already been brought into tight-fitting engagement with the driving head 900 in the process of receiving the driving force from the driving head 900, the rotational power receiving part 110 of the driving assembly 100 cannot be retracted axially inward to be disengaged from the driving head 900.
Therefore, if the above phenomenon occurs, the user cannot smoothly take the process cartridge out of the electronic image forming apparatus, and if the user forcibly takes the process cartridge out of the electronic image forming apparatus, the driving head of the electronic image forming apparatus or the rotational power receiving member of the process cartridge is easily worn or broken, so that it is difficult or impossible to stably engage and transmit the power between the driving head and the rotational power receiving member, and thus the electronic image forming apparatus or the process cartridge cannot be used normally, and the subsequent developing quality is also affected to a different extent.

In addition, there is a photosensitive assembly a cooperating with the process cartridge b to perform the developing operation, the photosensitive assembly a includes a photosensitive bin a100 and a driving member a110 disposed at one side of the photosensitive bin a100, the driving member a110 is engaged with another driving head 900a in the electronic image forming apparatus to receive the rotational driving force and transmit the driving force to the photosensitive unit 10 in the photosensitive bin a100, and the driving member a110 is preferably a convex triangular structure.
In which a process cartridge b and a photosensitive member a can be mounted to an electrophotographic apparatus, respectively, see fig. 4. The electrophotographic apparatus P includes a main frame for mounting a process cartridge b and a photosensitive member a; preferably, the process cartridge b and the photosensitive assembly a can be mounted in the electronic image forming apparatus along different mounting rails, respectively; referring to fig. 4, the electronic image forming apparatus is provided with a mounting rail F100 of the process cartridge b, a mounting rail F200 of the photosensitive assembly a, and an openable and closable door cover P1; the mounting rails F100 and F200 are used to guide the mounting of the process cartridge and the photosensitive member and to function as supports for the process cartridge and the photosensitive member, respectively.

Meanwhile, the power receiving part 210 on the cartridge is disengaged from the driving head 900 provided in the electronic image forming apparatus; when the photosensitive unit and the developing unit are in a mutual contact position, the power receiving part 210 on the processing box is engaged with the driving head in the electronic imaging device again to transmit power.

The specific implementation mode can be the following technical scheme:

The other end of the control part 62c is provided with a rotatable part, the rotatable part is hinged with the control part 62c at a hinge point 62c2, and the rotatable part comprises a first matching part 62c3 and a second matching part 62c 4; the first engaging portion 62c3 is fixed relative to the second engaging portion 62c4 and can rotate together about a hinge point 62c2 relative to the control unit 62 c. The slidable component g4 driven by the motor of the electronic imaging device through a cam mechanism, when the cam controls the sliding component g4 to move in the X direction shown in fig. 15, the first urging part g41 arranged at the front end of the sliding component g4 first contacts with the first matching part 62c3, and with the movement of the sliding component g4, the matching part 62c3 is forced to rotate around the hinge point 62c2 together with the second matching part 62c 4; when the first engaging portion 62c3 is rotated to contact the stopper 71 provided in the process cartridge b, the stopper 71 is movably provided relative to the casing of the process cartridge b, and preferably, one end of the stopper 71 abuts against one end of an elastic member s4, and one end of the elastic member s4 is fixed relative to the casing of the process cartridge b.
Referring to fig. 16 and 17, when the first mating portion 62c3 rotates together with the second mating portion 62c4, the first mating portion 62c3 causes the stopper portion 71 to urge the elastic element s4 to have a certain amount of compression, the first mating portion 62c3 keeps in contact with the stopper portion 71, and the second mating portion 62c4 rotates and then contacts with the second urging portion g42 arranged on the sliding part g4, the sliding part g4 continues to move in the X direction, the second mating portion 62c4 is urged by the second urging portion g42 to move the control part 62c, and the rotating part 640 is driven to rotate at an angle, so that the assembly of the rotating part 640 and the guide sleeve 650 controlled by the control part 62c controls the power receiving part 210 to extend along the axis Y direction to receive power.
When the force of the motor on the sliding member g4 is gradually reduced or cancelled, the sliding member moves in the direction opposite to the direction X under the resilience of the elastic element s1, the rear side of the first urging portion g41 contacts the second matching portion 62c4 and reverses the second matching portion 62c4 and the first matching portion 62c3, or the first matching reverses together with the second matching portion under the resilience of the elastic element s 4; the control part 62c is further connected to another elastic element s5, when the control part 62c drives the rotation part 640 to rotate, the elastic element s5 is compressed, and after the force applied to the control part by the sliding part g4 is removed, the control part s5 receives the elastic restoring force of the elastic element s5, so that the control part 62c drives the rotation part 640 to rotate reversely, and thus the power receiving part 210 can be retracted in the direction opposite to the Y direction under the action of the elastic element (see the elastic element s3 provided in the first embodiment) arranged along the axial direction of the power receiving part 210.
