As shown in fig. 1, the driving assembly 100 of the present invention includes a power receiving part 101, a power transmitting part 102, and a power driving part 103; the rotating force is used for receiving the host driving head of the image forming device and transmitting the rotating force to the photosensitive drum through the photosensitive drum hub arranged at the end part of the photosensitive drum so as to drive the photosensitive drum to rotate. When the driving assembly receives and transmits the rotating force of the driving head of the host machine, the driving assembly is provided with a rotating axis, the rotating axis is superposed with the axis of the photosensitive drum, and at the moment, the power transmission part is in a state of not deviating from the bending deformation of the axis of the photosensitive drum. When the processing box containing the photosensitive drum is installed in the image forming device host and removed from the image forming device host, the power transmission part is in a state of bending deformation deviating from the axis of the photosensitive drum.

The power receiving portion 101 has an inverted cone-shaped body, and the top (outer edge of the bottom of the cone) has a pair of teeth 101a protruding upward, and the number of the teeth 101a may be four. The power receiving portion 101 is fixed to a receiving portion base 101b in an inverted state, the receiving portion base 101b has a downwardly protruding loop portion 101c, and the power receiving portion 101 is connected to the power transmitting portion 102 through the loop portion 101 c.
The power transmission part 102 is composed of at least two steel rings which are nested and connected with each other, and of course, the number of the steel rings can be set according to the requirement, and also can be three or four, or more. The power transmission unit 102 connects the power receiving unit and the power driving unit, and transmits power from the drive receiving unit to the power driving unit. The steel ring positioned at the uppermost position (far from the photosensitive drum) in the power transmission part 102 is buckled on the buckle part 101 c; the nested steel rings can move relatively to each other, so that the power transmission part can be bent to deviate from the axis of the photosensitive drum.
The power driving part 103 is a rigid body, and may be in the shape of a cylinder, a prism, a sheet, or the like, or may be a steel ring having a cylindrical shape and a bending deformation form in which the power driving part 103 passes through the power transmission part 102 and is positioned at the lowermost position.
In this embodiment, the steel ring and the ring buckle 101c are rectangular rings, and after the power driving portion 103 passes through the steel ring of the power transmission portion 102 located at the lowest position (close to the photosensitive drum), only a small gap is formed between the rigid rings nested with each other for relative rotation, and the relative displacement is limited, which is beneficial to limiting the relative displacement of the driving assembly along the rotation axis direction when the driving assembly receives and transmits the rotation force of the driving head of the host machine, and affects the driving assembly to transmit the power to the photosensitive drum, and affects the stability of the driving force.
The photosensitive drum hub 200 is arranged at an end of the photosensitive drum, as shown in fig. 2, a through hole 200a for a driving component to pass through is formed in the top of the photosensitive drum hub 200, the power transmission part 102 passes through the through hole 200a, the power receiving part 101 is exposed out of the through hole 200a, the power driving part 103 is located in the through hole 200a, a fixing hole 201 arranged along the radial direction of the bottom side wall of the photosensitive drum hub 200 is formed in the bottom side wall of the photosensitive drum hub 200, the power driving part 103 is inserted into the fixing hole 201, and two ends of the power driving part are fixed on the photosensitive drum hub; the axis of the power driving part is perpendicular to the axis of the photosensitive drum, and the power driving part 103 can drive the photosensitive drum hub 200 when being stressed to rotate, so as to drive the photosensitive drum to rotate.
The process of matching the driving unit of this embodiment with the image forming apparatus main body driving head 300 will be described. As shown in fig. 3, before the process cartridge is loaded into the image forming apparatus main body, the power transmission portion is subjected to a prestressing force, so that the power transmission portion is subjected to bending deformation in the mounting direction of the process cartridge, that is, the power transmission portion 102 is subjected to bending deformation relative to the axis L of the photosensitive drum under the action of the prestressing force; due to the curvature of the power transmitting portion 102, the power receiving portion 101 is brought into contact with the driving head 300 of the image forming apparatus in advance while obtaining an installation space, to facilitate the engagement of the power receiving portion 101 and the driving head 300 after the completion of the subsequent installation.
As shown in fig. 4, when the process cartridge is completely mounted in the image forming apparatus main body, after the engagement of the driving assembly with the driving head 300 is completed, the power transmission portion 102 is restored to the initial state, i.e., the power transmission portion 102 is not substantially bent with respect to the photosensitive drum axis L; then under the action of the rotating force of the driving head, the driving head 300, the power receiving part 101, the power transmission part 102, the power driving part 103 and the photosensitive drum are coaxial, so that the driving force of the driving head can be well transmitted to the photosensitive drum through the driving assembly, and the photosensitive drum can stably rotate along with the driving head 300.
Example 2
As shown in fig. 5 and 6, the present embodiment is different from embodiment 1 in that: the driving assembly further comprises a limiting component 104 arranged along the driving assembly, wherein the limiting component 104 has the characteristics that when the driving assembly receives a force from the end part direction (along the axial direction of the induction drum), the limiting component does not generate bending deformation, and when the driving assembly receives forces from other directions, the limiting component can generate bending deformation deviating from the axial direction of the induction drum; the limiting part 104 is a steel strip-shaped sheet, and can also be a sheet or a thin tube made of polyethylene; the stopper 104 has one end connected to the power receiving portion 101 and the other end connected to the drum hub 200. In this embodiment, a protruding pillar 101d protruding horizontally is disposed on the receiving portion base 101b, a positioning hole 200b is disposed in the photosensitive drum hub 200, one end of the limiting component 104 is connected to the protruding pillar 101d, and the other end is fixed in the positioning hole 200 b. The limiting component 104 is arranged on one side of the drive transmission part 102 deviating from the axis L of the photosensitive drum, when the drive transmission part 102 deviates from the axis L of the photosensitive drum, the limiting component 104 can be driven to also deviate from the axis L of the photosensitive drum to bend in the radial direction, and the limiting component 104 can generate certain stress when being bent by external force, so that the power transmission part is prevented from being deformed too much, and meanwhile, the resetting of the power transmission part can be assisted.
As shown in fig. 7, before the process cartridge is installed in the image forming apparatus main body, the power transmitting portion is pre-stressed to bend and deform the power transmitting portion in the mounting direction of the process cartridge, that is, the power transmitting portion 102 bends relative to the axis L of the photosensitive drum under the pre-stress, and the limiting member 104 is also bent along with the power transmitting portion 102, so that a certain stress is generated when the limiting member 104 is compressed away from the axis L, so that the power receiving portion 101 keeps the head 300 in contact with the driving head 300 during the mounting process, and the situation that the power receiving portion 101 may move away from the axis L of the photosensitive drum, so that the power receiving portion 101 is separated from the driving head 300 and is inconvenient to mount is avoided.
As shown in fig. 8, when the process cartridge is completely mounted in the image forming apparatus main body, after the engagement of the driving assembly with the driving head 300 is completed, the power transmitting portion 102 is restored to the initial state, i.e., substantially in the state of being disposed along the photosensitive drum axis L, and then the driving head 300, the power receiving portion 101, the power transmitting portion 102, the power driving portion 103, and the photosensitive drum are brought into coaxial alignment by the rotational force of the driving head. In addition, due to the existence of the limiting component 104, the power receiving part 101 can be tightly extruded to the driving head 300 along the axis L direction of the photosensitive drum, so that the engagement of the power receiving part 101 and the driving head 300 is ensured, the power receiving part and the driving head 300 cannot be disengaged in rotation, the driving force of the driving head is transmitted to the photosensitive drum through the driving component, and the photosensitive drum can stably rotate along with the driving head 300.
