Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

The following describes the power receiving device 100 according to an embodiment of the present invention with reference to fig. 1 to 4, where the power receiving device 100 is applied in an image forming cartridge, where the image forming cartridge may further include: a cartridge body, and a power receiving device 100 is installed at one side of the cartridge body in an axial direction for receiving power from the inside of the image forming apparatus. The imaging cartridge may be a compact.

As shown in fig. 1 to 4, a power receiving device 100 according to an embodiment of the present invention may include: the first receiving member 10 is provided with a shaft hole 11, and the outside of the first receiving member 10 may be provided with a tooth portion 12, the tooth portion 12 being for engagement with a gear inside the magazine, so that power transmission may be achieved.

The second receiving member 20 passes through the shaft hole 11, and the second receiving member 20 rotates synchronously with the first receiving member 10, so that power can be transmitted between the two. The end of the second receiving member 20 away from the first receiving member 10 is a receiving head 21, and as shown in fig. 1, the left end of the second receiving member 20 is provided as the receiving head 21, and the receiving head 21 is used for limiting the position of the claw 40. Specifically, when the claw 40 receives the rotating force, it drives the receiving head 21 to rotate, and further drives the first receiving member 10 and the second receiving member 20 to rotate.

As shown in fig. 1 to 3, the receiving head 21 is provided with a radially extending limiting groove 23. The second receiving member 20 is further provided with an accommodating groove 24 communicating with the stopper groove 23 inside the receiving head 21. Part or all of the transformation body 30 may be received in the receiving groove 24. The claw 40 is partially disposed in the stopper groove 23. Preferably, the latch 40 is mounted on the end of the deforming body 30 to move relative to the second receiving member 20 when pressed by the drive head. It can be understood that the deformable body 30 has a deformation capability, so that when the driving head is in installation and butt joint with the jaw 40, the driving head can transmit a certain pressure to the jaw 40, and the deformable body 30 can deform under the action of the pressure and can swing or contract to drive the jaw 40 to move towards the right side, the right side can be the direction towards the right as shown by the arrow in fig. 1-4, or can rotate relative to the end part, connected with the deformable body 30, of the jaw 40 in the limit groove 23, the rotation direction can be arbitrary, and the rotation amplitude is limited by the limit groove 23. When the drive head is in place, the pressure that the drive head will transmit to the jaws 40 will be removed or reduced, thereby resetting the deformable body 30 and thus the jaws 40. This enables the drive head to fit within the receiving head 21 and the jaws 40 to be circumferentially captured by the drive rod on the drive head, which enables the transmission of force to be carried out when the jaws 40 receive a driving force.

Therefore, the deformation body 30 and the clamping jaw 40 are arranged on the second receiving part 20, the clamping jaw 40 can be moved or rotated when the driving head and the receiving head 21 are butted or disassembled conveniently, the clamping jaw 40 is prevented from being clamped by the driving head of the imaging equipment, and the power receiving device 100 is simple in structure and convenient to assemble, so that the assembling difficulty of the power receiving device 100 can be reduced.

Alternatively, as shown in fig. 4, the axial length of the transformation body 30 is greater than the depth of the accommodation groove 24. That is to say, the length of the deformable body 30 in the left-right direction is greater than the length of the accommodating groove 24 in the left-right direction, so that the end portion of the deformable body 30 extends out of the accommodating groove 24, and the end portion of the deformable body 30 is located in the accommodating groove 24, in other words, the installation positions of the clamping jaw 40 and the deformable body 30 are located in the limiting groove 23, so that the clamping jaw 40 rotates or moves more flexibly when receiving non-driving force, and the installation is more convenient. The driving force may include a force for pushing the two pawls 40 to rotate about the axis of the deformed body 30, for example, a force for normally working the driving head of the image forming apparatus with the pawls 40. The axis may be parallel to the left-right direction as shown in fig. 4. The non-driving force is a force acting on the pawl in addition to the driving force. For example, the non-driving force is a force generated when the driving head in the image forming apparatus abuts against an unspecified portion 40 when the power receiving device 100 is attached to or detached from the image forming apparatus. When the non-driving force is larger than the force with which the deformation body 30 is deformed, the deformation body 30 may be deformed after the non-driving force is applied to the jaws.

The limiting groove 23 can limit the circumferential deformation of the end part of the claw 40 receiving the driving force, but allows the deformation of the deformation body 30 along the radial direction and the axial direction, i.e. the deformation body can swing and stretch, so that the matching of the driving head and the receiving head 21 can be facilitated, the position of the claw 40 can be easily changed, and the claw 40 can be conveniently clamped with the circumferential direction of the driving rod of the driving head. Wherein, the end of the driving head can be a conical head, and the receiving head 21 can be formed with a conical groove into which the conical head can extend. The tapered groove may communicate with the stopper groove 23. The driving force may be such that a driving head of the image forming apparatus is rotated by a motor when the image forming apparatus is operated. After the power receiving device 100 is mounted to the image forming apparatus, the driving force can drive the pawls 40 to rotate, and since at least a part of the pawls 40 are located in the retaining grooves 23, the pawls 40 can be prevented from rotating relative to the receiving head 21 by the retaining grooves 23, thereby transmitting the driving force to the receiving head 21.

Specifically, as shown in fig. 3 and 4, the pawl 40 includes: the base 41, two dopes 42 and installation head 43, two dopes 42 are installed at the both sides of base 41 and relative setting, and the top of dop 42 surpasss the top of receiving head 21, and installation head 43 is installed on base 41, and installation head 43 cooperatees with the somatome 30 moreover. The two clamping heads 42 can be circumferentially clamped with two driving rods of the driving head, the mounting head 43 can play a role in mounting with the deformation body 30, and the clamping jaws 40 arranged in the way are reliable in structure and reliable in function realization. The non-driving force can be a convex end part acting on a certain chuck 42, at the moment, the deformation body 30 deforms to enable the clamping jaws 40 to deflect towards the direction of the stressed chuck 42, and when the non-driving force is smaller than the force required by deformation of the deformation body 30, the deformation body 30 can reset, so that the clamping jaws 40 are driven to reset. The projecting end portion may be a portion of the chuck head 42 projecting in the left direction with respect to the receiving head 21.

Further, as shown in fig. 4, the deforming body 30 has a structure having an axial through hole 31, and the mounting head 43 is fitted in the axial through hole 31. Since the deformation body 30 has the axial through hole 31, on the one hand, deformation of the deformation body 30 can be facilitated, and on the other hand, assembly of the mounting head 43 with the deformation body 30 can be facilitated. Of course, the deformation body 30 may also be provided with mounting grooves only at the ends, and the mounting heads 43 may be fitted in the corresponding mounting grooves. In addition, a blind hole may be provided in an end portion of the mounting head 43 for contacting the deformable body 30, and a portion of the deformable body 30 may be inserted into the blind hole. The assembly of the jaws 40 with the deformable body 30 is also facilitated.

Optionally, as shown in fig. 4, the bottom of the receiving groove 24 is provided with a limiting post 27, and the limiting post 27 is fitted in the axial through hole 31. The limiting columns 27 are arranged at the bottoms of the accommodating grooves 24, so that the installation reliability of the deformation body 30 can be guaranteed, the deformation body 30 can be prevented from being separated from the accommodating grooves 24, and the installation reliability of the clamping jaws 40 can be further guaranteed. The axial through hole 31 may be interference-fitted with the mounting head 43 and may be interference-fitted with the stopper post 27, which may improve the mounting reliability of the claw 40.

As shown in fig. 4, the second receiving part 20 further includes: the shaft body 22, the end of the shaft body 22 is connected with the receiving head 21, the shaft body 22 passes through the shaft hole 11, and the shaft body 22 is provided with a containing groove 24. That is, the receiving groove 24 is formed at a side of the shaft body 22 adjacent to the receiving head 21, so that the deformable body 30 can be conveniently installed, and the stability of the fit between the receiving head 21 and the claw 40 can be ensured.

According to an embodiment of the present invention, as shown in fig. 3, the second receiving part 20 further includes: the baffle 25 is arranged on the shaft body 22, the baffle 25 is arranged at a distance from the receiving head 21, the first receiving part 10 is further provided with a stop 13 at the radial outer side of the shaft hole 11, and the stop 13 is circumferentially matched with the baffle 25 to realize synchronous rotation. It can be understood that the circumferential cooperation of the baffle 25 and the stopper 13 can enable the first receiving member 10 and the second receiving member 20 to rotate synchronously, and the cooperation of the baffle 25 and the stopper 13 is adopted, so that the reliability is high.

Wherein, the one end that the axis body 22 deviates from the receiving head 21 is provided with the torsional spring, and torsional spring and receiving head 21 are located the axial both sides in shaft hole 11. As shown in fig. 3 and 4, the end of the shaft body 22 away from the receiving head 21 is provided with a mounting hole 26, a torsion spring can be fitted near the mounting hole 26, and two ends of the torsion spring are connected to the shaft body 22 and the first receiving member 10, so that the second receiving member 20 can be reset relative to the first receiving member 10, and the mounting and dismounting of the imaging cartridge can be facilitated.

Alternatively, the deformation body 30 may be a rubber body, a plastic body, or a spring. The deformation bodies 30 of the above types have simple structures and can effectively deform, so that the position of the clamping jaw 40 relative to the second receiving part 20 can be changed, and the installation and matching of the driving head and the receiving head 21 can be facilitated.

In addition, the deformation generating force of the deformation body 30 may be in a range of a value greater than or equal to the first force and less than the second force. The first force may be a force generated when the driving head is in a stationary state in the image forming apparatus to press the claw 40 when the power receiving device 100 is properly mounted in the image forming apparatus. The second force may be a force generated by the drive head pressing the pawl 40 when the power receiving device 100 is not properly installed in the image forming apparatus, but the drive head has pressed the pawl 40 and the pawl 40 is in a zero-bound state where movement or rotation occurs. The zero limit state is that the jaws 40 are not moved or rotated, and if the force generated by the driving head pressing the jaws 40 is increased by a value greater than zero newton, the jaws 40 are moved or rotated.

The fitting manner of the power receiving device 100 and the driving head according to the embodiment of the present invention will be described in detail.

In mounting the image forming cartridge to the image forming apparatus, if the end of the driving head is first brought into contact with the collet 42, the contacting collet 42 is rotated inwardly with the mating portion of the deforming body 30 and the mounting head 43 as a pivot position, the height of the collet 42 becomes gradually lower until the end of the driving head passes over the claw 40, at which time the claw 40 is restored by the deforming body 30, the tapered head of the driving head is fitted in the tapered groove of the receiving head 21, wherein the collet 42 on the other side is moved synchronously with the collet 42. If the end of the drive head first contacts the edge of the receiving head 21, the tapered head of the drive head may enter the tapered slot directly.

When the driving head and the power receiving device 100 transmit power, the driving rod of the driving head and the chuck 42 of the jaw 40 are circumferentially held to perform power transmission, the stopper groove 23 limits the degree of freedom of the jaw 40, power can be transmitted to the second receiving member 20, the second receiving member 20 transmits power to the first receiving member 10 through the cooperation of the stopper 13 and the shutter 25, and the first receiving member 10 transmits power to the gear at the case through the tooth portion 12, so that corresponding image forming work can be performed.
