technical field

The present invention relates to a drive assembly and its process cartridge and electronic imaging device.

Background technique

In the related art, the process cartridge is detachably mounted on the electronic imaging device. The electronic imaging device is provided with a drive head that outputs a rotational driving force. The process cartridge generally includes a drive assembly that receives rotational force, a developing unit, a developer, a powder control unit, and a housing for accommodating the above-mentioned units. In addition, according to different types of process cartridge structures, a photosensitive unit, a charging unit, a cleaning unit, and a cleaning unit are additionally provided. unit and stirring unit, etc. The drive assembly of the process cartridge is arranged at one end of the process cartridge along the axial direction of the developing unit or the photosensitive unit. After the drive assembly engages with the drive head in the electronic imaging device, the rotating driving force is transmitted to the process cartridge, and finally Drive the rotating units (such as developing units, photosensitive units, stirring units, etc.) inside the process cartridge to rotate, and participate in the developing operation of the electronic imaging device.

Before the electronic imaging device performs the developing operation (that is, the so-called "printing"), the user needs to install the process cartridge into the electronic imaging device. .

As shown in FIG. 1, the process cartridge C is installed in an electronic imaging device (not shown) along a direction X1 (the direction X1 is substantially perpendicular to the axial direction of the developing unit), and the process cartridge C passes through the left and right inner panels in the electronic imaging device. The guide rails (F11, F21) support and guide the process cartridge C into the electronic image forming apparatus. When the process cartridge C is installed into the electronic imaging device along the guide rails ( F11 , F21 ), as shown in FIG. 2 , the drive assembly 100 located at one end of the process cartridge C also moves along the direction X1 and then interacts with the driving head 900 on the electronic imaging device. Contact engagement, since the drive head 900 is relatively fixed in the electronic imaging device (can only rotate along its own axis), during the process of the drive assembly 100 moving along the direction X1 to contact and engage with the drive head 900, the rotational power of the drive assembly 100 is received. The component 110 will have a certain probability to form structural interference with the drive head 900 . Therefore, in the prior art, when the rotational power receiving member 110 forms structural interference with the driving head 900 , the rotational power receiving member 110 is squeezed from the driving head 900 to retract inward along its axial direction to avoid structural interference. . When the rotary power receiving member 110 continues to move to be substantially coaxial with the driving head 900 , the structural interference between the rotary power receiving member 110 and the driving head 900 disappears, and the rotary power receiving member 110 is due to the spring provided inside the driving assembly 100 . The elastic force of the pin sticks out and engages 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 formed a tight-fitting engagement state with the driving head 900 in the process of receiving the driving force from the driving head 900, the driving The rotational power receiving member 110 cannot be retracted axially inward out of engagement with the drive head 900 .

Therefore, if the above phenomenon exists, the user cannot smoothly remove the process cartridge from the electronic imaging device. If the user forcibly removes the process cartridge from the electronic imaging device, the driving head of the electronic imaging device or the process cartridge may be easily rotated. The power receiving part is worn or broken, making it difficult or impossible for the drive head and the rotating power receiving part to continue to engage and transmit power stably, so that the electronic imaging device or the process cartridge cannot continue to be used normally, and the subsequent development quality will also be affected. degree of influence.
