[0025] In order to make the purpose, technical solution and technical effect of the embodiment of the present invention more clear, the technical solution of the process cartridge of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiment described is only a preferred embodiment of the present invention, not the only embodiment. Based on the embodiment of the present invention, other embodiments obtained by those skilled in the art without creative effort shall fall within the scope of protection of the present invention.

[0026] Example 1

[0027] To facilitate the description of the processing box 100 in the present invention, the various directions of the processing box 100 will be defined below. The length direction of the processing box 100 is the left-right direction, which is also the direction in which the rotation axis of the photosensitive drum 102 (i.e., the photosensitive drum rotation axis) extends. In the left-right direction, the electrical contact surface 121 of the chip 120 is arranged at the left end of the processing box 100; the up-down direction is perpendicular to the left-right direction, and the electrical contact surfaces 121 of the photosensitive drum 102 and the chip 120 are arranged in the up-down direction, and the electrical contact surface 121 in the up-down direction is set at the upper end of the processing box 100; the front-to-back direction is perpendicular to both the left-right direction and the up-down direction.

[0028] like Figure 1-7 As shown, in embodiment 1 of the present invention, a process cartridge 100 is disclosed, which is detachably mounted in a back-to-front direction in an image forming apparatus having a power supply component, an electrical contact, and a driving force applying member.

[0029] The processing box 100 includes a frame 110, which includes a frame main body 110a that can accommodate the developer and a first protective cover 111 and a second protective cover 112 respectively arranged on the left and right sides of the frame main body 110a. In the present utility model, the first protective cover 111 and the second protective cover 112 are installed on the frame main body 110a in a detachable manner. Optionally, the first protective cover 111 and the second protective cover 112 can also be integrally formed with the frame main body 110a.

[0030] The processing box 100 also includes a developing roller (not shown) supported on the frame 110, a photosensitive drum 102 and a charging roller (not shown), wherein when the processing box 100 performs printing work, the developing roller carries a developer, and the charging roller can uniformly charge the photosensitive drum 102. After the charged photosensitive drum 102 is selectively irradiated by the laser in the imaging device, an electrostatic latent image can be formed on the outer surface of the photosensitive drum 102. The developing roller can transport the developer carried on the developing roller to the photosensitive drum 102 through contact with the photosensitive drum 102 to develop the electrostatic latent image thereon and form a developer image on the photosensitive drum 102. Subsequently, the developer image can be transferred to the transfer belt through contact between the photosensitive drum 102 and the transfer belt of the imaging device. Finally, the transfer belt can transfer the developer image to a recording medium (such as paper). The processing box 100 also includes a coupling member 120 (coupling protrusion 120), and the first protective cover 111 can cover at least a portion of the coupling member 120. The coupling member 120 has a coupling portion 120a arranged at the right end of the frame 110. The coupling portion 120a can be coupled with the driving force applying member of the imaging device and can receive the rotational driving force output by it to rotate, thereby driving the developing roller and the photosensitive drum 102 to rotate.

[0031] The processing box 100 also includes a first electrode 113 provided on the frame 110. The first electrode 113 has a first electrode electrical contact surface 113a that can be electrically contacted with the power supply component of the imaging device. The first electrode 113 is provided at the upper right end portion of the frame 110 and faces the upper end of the processing box 100. Specifically, the first electrode 113 is provided on the first protective cover 111. The first electrode electrical contact surface 113a can supply the power to the charging roller. That is, the first electrode 113 can receive the power of the imaging device and supply the received power to the charging roller to ensure that the charging roller can charge the photosensitive drum 102. It is worth mentioning that when the processing box 100 is installed in the imaging device, the power supply component of the imaging device can elastically contact the first electrode electrical contact surface 113a downward, and the elastic contact produces The pushing force can press the processing box 100 downward, so that the positioning of the processing box 100 in the imaging device becomes more stable. That is to say, the first electrode 113 is arranged at the upper end of the processing box 100 and is in elastic contact with the power supply component. While realizing power supply to the charging roller, it can also improve the positioning stability of the processing box 100; the processing box 100 is also provided with a second electrode 114 located on the frame 110, and the second electrode 114 has a second electrode electrical contact surface 114a that can be electrically contacted with another power supply component of the imaging device. It is arranged at the right end part of the frame 110 and faces the right end of the processing box 100. The second electrode 114 can receive power from the imaging device and supply the received power to the developing roller and the powder feeding roller (not shown) to ensure the normal operation of the charging processing box 100.

[0032] Furthermore, the processing box 100 further includes a chip 131 disposed on the frame 110 and a chip mounting position 130 for supporting and accommodating the chip 131. Specifically, the chip 131 and the chip mounting position 130 are disposed on the upper side of the first protective cover 111 and are disposed adjacent to the first electrode 113 in the front-to-back direction. The chip 131 is generally T-shaped. Of course, the shape of the chip 131 is not fixed and may be other shapes. The chip 131 includes a rigid substrate 131a and a chip electrical contact surface 131a that can be electrically contacted with an electrical contact head of the imaging device. 1b, a storage unit 131c storing information related to the process cartridge 100, the chip electrical contact surface 131b and the storage unit 131c are electrically connected via a bent portion 131e provided thereon, wherein the chip electrical contact surface 131b of the chip 131 is arranged on the surface of the substrate 131a and faces the upper end of the process cartridge 100, thereby being exposed to the outside of the process cartridge 100, and can be elastically contacted with an electrical contact provided at the upper end thereof and located on the imaging device, and the pushing force generated by the elastic contact can press the process cartridge 100 downward, making the positioning of the process cartridge 100 in the imaging device more stable. In other words, the chip 131 is arranged at the upper end of the processing box 100 and is in elastic contact with the electrical contact. While realizing the communication connection with the imaging device, the positioning stability of the processing box 100 can also be improved. In this embodiment, the chip electrical contact surface 131b and the first electrode electrical contact surface 113a are arranged at a certain distance in the front-to-back direction to avoid mutual electrical interference between the two. In addition, compared with the first electrode electrical contact surface 113a, the chip electrical contact surface 131b is arranged at a position closer to the front end of the processing box 100 in the front-to-back direction. From the foregoing description, it can be known that the chip electrical contact surface 131b and the first electrode electrical contact surface 113a are both arranged at the left end of the processing box 100, that is, at the opposite end of the coupling member 120 in the left-right direction, and can be as far away from the coupling member 120 as possible. In this case, the degree of jitter at the left end of the processing box 100 will be smaller than that at the right end, and the chip electrical contact surface 131b and the first electrode electrical contact surface 113a will become more stable when they are respectively electrically connected to the imaging device, thereby improving the electrical connection stability with the imaging recognition.

[0033] The chip 131 also includes a power supply portion 131d supported on the substrate 131a. The power supply portion 131d stores electrical energy. In the up and down directions, the power supply portion 131d is arranged on the lower side of the chip electrical contact surface 131b to avoid interference with the chip connection components in the imaging device. The power supply portion 131d can independently supply power to the storage portion 131c. Even after the chip 131 is disconnected from the electrical contacts of the imaging device, the power supply portion 131d can continue to supply power to the chip 131 so that the storage portion 131c has enough time to save data. This can effectively reduce the possibility of data in the storage portion 131c being lost due to lack of time to store data after the chip 131 is disconnected from the electrical contacts of the imaging device. Preferably, the power supply component 131d It is a button battery, which has the advantages of sufficient power and small size, and can effectively reduce the size of the chip 131, which is conducive to the miniaturization of the processing box 100; as the chip 131 is already provided with a power supply part 131d, in order to avoid the power supply part 131d from interfering with the processing box 100 when the chip 131 is installed in the processing box 100, an avoidance part 132 is further provided on the chip mounting position 130 of the first protective cover 111 of the frame 110, and the avoidance part 132 can avoid the power supply part 131d to allow the chip 131 to be matched and installed on the processing box 100; preferably, the avoidance part 132 is a groove structure formed on the first protective cover 111, and part of the substrate 131a and the power supply part 131d can be accommodated in the groove and can be stably positioned.

[0034] Example 2

[0035] Next, the second embodiment of the present invention will be described. Figure 7As shown, a processing box 200 is shown. The similarities between the processing box 200 and the processing box 100 in Example 1 are not repeated here. The difference is that the chip 231 is a flexible printed circuit board. Compared with a rigid circuit board, a flexible printed circuit board has good flexibility, high wiring density, light weight, thin thickness, and good bendability. On the one hand, this can separate the chip electrical contact surface 231b from the storage part 231c and the power supply part at a certain distance, so that except for the chip electrical contact surface 231b being arranged in the original position, the other parts are connected to the chip electrical contact surface 231b through the flexible circuit board. The originally narrow chip mounting position is only arranged with the chip electrical contact surface 231b, and other parts such as the storage part 231c and the power supply part can be arranged in other spacious positions, thereby improving the design freedom of the chip 231 arrangement; on the other hand, it also avoids its connection with the chip 231. The possibility of damaging the storage unit 231c and the power supply unit when the electrical contacts of the imaging device contact and press the chip; further, in order to facilitate the rapid installation of the chip 231 on the frame 210, at least a portion of the avoidance portion 132d provided on the frame 210 is exposed at the left end of the processing box 200. In this way, on the left side of the processing box 200, the operator has a larger operating space to quickly install the chip 231 on the frame 210 along the direction from left to right. Through this structure, the bent portion 231e of the chip 231 is provided at the left end of the chip 231 to facilitate the installation of the chip 231. That is, when the chip 231 is defined as having a first end and a second end in the left-right direction, the first end is farther away from the right end of the frame 210 than the second end. In the left-right direction, the bent portion 231e is provided at a position closer to the first end of the chip 231 than the second end of the chip 231.
