Fig. 3 is a perspective view of an action mechanism according to an embodiment of the present invention; fig. 4A is a schematic view of a state of an unlocking assembly according to a first embodiment of the present invention in a first position; fig. 4B is a schematic view of a state of the unlocking assembly according to an embodiment of the present invention in the second position.

The action mechanism 400 includes a force receiving member 41, a movable member 42 and a force conversion member located between the force receiving member 41 and the movable member 42, in this embodiment, the force conversion member is a connection member 43 connecting the force receiving member 41 and the movable member 42, wherein the force receiving member 41 is configured to receive a downward acting force, the connection member 43 is a force conversion member configured to transmit the downward acting force to the movable member 42, so as to force the movable member 42 to move forward along a front-back direction, and further release the locking between the locking surface 203 and the limiting surface 105, preferably, the elastic member 500 is combined with the force receiving member 41, in a process of resetting the action mechanism 400, the acting force of the elastic member 500 can be more directly applied to the force receiving member 41, as shown in fig. 3, the force receiving member 41 includes a force receiving portion 411, an elastic member combining portion 412 and a limiting portion 413 connected with the force receiving portion 411, the force receiving portion 411 is further provided with a rib 414 configured to increase a friction force, one end of the elastic member 500 abuts against the elastic member combining portion 412, the other end abuts against the housing, and the limiting portion 413 is combined with the housing, so as to prevent the force receiving member 41 from falling off from the housing, and limit a moving direction of the force receiving member 41 to an up-down direction.

The moveable member 42 includes a main body 421, a raised surface 422 extending from the main body 421, and a retaining surface 423 disposed adjacent to the raised surface 422. As shown in fig. 4A and 4B, when the movable element 42 does not receive the acting force, the locking surface 203 abuts against the limiting surface 105, the locking element 200 does not contact with the unlocking assembly 300, and at this time, the unlocking assembly 300 is located substantially behind the locking element 200 and is located at the first position, and along the up-down direction, a certain point/specific point a of the lifting surface 422 (which may be any point of the lifting surface, such as the front end point of the lifting surface) has a first projection point B on the locking element 200, and preferably, along the front-back direction, the first projection point B is located between the locking surface 203/limiting surface 105 and the rotation axis L; when the movable member 42 receives the acting force, the main body 421 moves forward on the housing, the lifting surface 422 lifts the locking member 200 so that the locking member 200 rotates integrally about the rotation axis L, when the locking member 200 reaches above the movable member 42 integrally, the locking member 200 is held by the holding surface 423, the locking of the locking surface 203 with the stopper surface 105 is released, and the ink cartridge 100 can be taken out smoothly, at which time the unlocking member 300 is in the second position, and in the up-down direction, a certain point/specific point a of the lifting surface 422 has a second projected point C at the locking member 200, and in the front-back direction, the second projected point C is located between the locking surface 203/stopper surface 105 and the rotation axis L, and the second projected point C is located forward of the first projected point B, or the second projected point C is farther from the rotation axis L than the first projected point B, or the second projected point C is closer to the stopper surface 105/locking surface 203 than the first projected point B, that is, when the ink cartridge 100 needs to be unlocked, the unlocking member 300 is in a position farther from the rotation axis L or in a position closer to the stopper surface 105/locking surface 203 than the first projected point B, and thus the locking member 200 can be easily pushed, and the acting force can be applied to the ink cartridge 100, and the locking member 200 can be more easily. The lifting surface 422 may be a plane parallel to the up-down direction, or an inclined surface inclined with respect to the up-down direction, and relatively speaking, the lifting surface having the inclined surface is more labor-saving, so that the lifting surface 422 is preferably an inclined surface, the inclined direction is that, along the front-back direction, the front side of the lifting surface 422 is closer to the housing/main body 421 than the rear side, and an included angle formed between the lifting surface 422 and the rear direction is an acute angle, and the smaller the included angle is, the smoother the movement of the movable member 42 is; preferably, the housing is provided with a guide portion 107 extending in the front-rear direction, and the guide portion 107 is groove-shaped for guiding the main body 421, so that the movement locus of the movable member 42 can be determined.

The first connecting portion 43a is arranged between the connecting member 43 and the force receiving member 41, and the second connecting portion 43b is arranged between the connecting member 43 and the movable member 42, wherein at least the second connecting portion 43b is movably connected, for example, the connecting member 43 and the movable member 42 are connected by a spring, a fixed pin shaft, and a flexible material, so that the connecting member 43 is movable relative to the movable member 42, and the connecting member 43 can transmit the acting force to the movable member 42 through the second connecting portion 43 b. The connection mode of the first connection portion 43a is not limited, that is, the connection between the connection portion 43 and the force-receiving member 41 may be rigid, or may be the same as the connection mode of the second connection portion 43b, in this embodiment, the connection portion 43 itself is made of an inflexible material so that the connection portion 43 does not elastically deform, and the loss of the acting force in the transmission process through the connection portion 43 can be reduced, and then, in the transmission process of the acting force from the connection portion 43 to the movable member 42 through the second connection portion 43b, even if the relative position between the connection portion 43 and the movable member 42 is not favorable for the transmission of the acting force, under the action of the acting force, the connection portion 43 can move relative to the movable member 42 by an angle, so that the connection portion 43 reaches a position which is more favorable for the transmission of the acting force to the movable member 42.

When the connecting member 43 is rigidly connected to the force-receiving member 41, as described above, the second connecting portion 43b between the connecting member 43 and the movable member 42 is movably connected, so that the connecting member 43 can move relative to the movable member 42 to a position favorable for transmitting the acting force; when the connecting member 43 and the force-receiving member 41 are movably connected, it can be understood that, after the connecting member 43 has moved by an angle relative to the movable member 42, even if the connecting member 43 is still at a position unfavorable for transmission of the acting force relative to the movable member 42, the acting force can first force the connecting member 43 to move by an angle relative to the force-receiving member 41, so that the acting force can be smoothly transmitted from the force-receiving member 41 to the connecting member 43, and then the connecting member 43 moves by another angle relative to the movable member 42, so that the acting force can be smoothly transmitted from the connecting member 43 to the movable member 42, and thus, when the first connecting portion 43a and the second connecting portion 43b are both movably connected, the acting force applied from top to bottom to the force-receiving member 41 can be more easily transmitted to the movable member 42.

Fig. 5 shows the comparison of the relative positions of the force-receiving member 41, the connecting member 43 and the movable member 42 before and after the force is transmitted to the action mechanism 400, wherein the force-receiving member 41 is limited to move only in the up-down direction, and the movable member 42 is limited to move only in the front-back direction, so that the connecting member 43 serves as a force conversion member for converting the downward force received by the force-receiving member 41 into a force for forcing the movable member 42 to move forward. Before the effort is applied to the forced piece 41, along the fore-and-aft direction, the moving piece 42 is close to the forced piece 41, when the effort from top to bottom is applied, the forced piece 41 moves down along the up-and-down direction, the elastic piece 500 is compressed and deformed, the connecting piece 43 pushes the moving piece 42 to move forward through the second connecting portion 43b, meanwhile, the first connecting portion 43a moves down together with the forced piece 41, along the fore-and-aft direction, the included angle between the connecting piece 43 and the backward direction gradually decreases, the effort from top to bottom is converted into the effort/the thrust from back to front, the moving piece 42 is forced to move forward by the first distance g1, the unlocking assembly 300 moves from the first position to the second position, at this moment, along the fore-and-aft direction, the moving piece 42 is far away from the forced piece 41. As can be seen from fig. 5, when the first connecting portion 43a is in the movable connection mode, in the second position, the angle between the connecting portion 43 and the backward direction is smaller, and accordingly, the distance g that the movable member 42 moves forward is larger. Once the acting force from top to bottom is removed, the force-bearing member 41 is reset upwards under the elastic reset force of the elastic member 500, and at the same time, the connecting member 43 pulls the movable member 42 to reset, so that the unlocking assembly 300 returns from the second position to the first position.

[ example two ]

Fig. 6 is a perspective view of an action mechanism according to a second embodiment of the present invention; fig. 7 is a comparison diagram of the state of the action mechanism according to the second embodiment of the present invention before and after the action force is applied.

For simplicity, the same components in this embodiment are numbered the same as those in the previous embodiment, and as shown in fig. 6, the action mechanism 400 in this embodiment still includes the force receiving member 41, the movable member 42 and the force conversion member, in this embodiment, the force conversion member is a connecting member 43', the connecting member 43' connects the force receiving member 41 and the movable member 42, the force receiving member 41 is used for receiving a downward acting force, the connecting member 43' is used as the force conversion member for transmitting the downward acting force to the movable member 42, so as to force the movable member 42 to move forward in the front-back direction, and release the locking between the locking surface 203 and the limiting surface 105; the moveable member in this embodiment also includes a main body 421, a raised surface 422 extending from the main body 421, and a retaining surface 423 disposed adjacent to the raised surface 422.

As shown in fig. 6, a first connection portion 43a ' is disposed between the connection member 43' and the force-receiving member 41, and a second connection portion 43b ' is disposed between the connection member 43' and the movable member 42, wherein at least the second connection portion 43b ' is movably connected, and the specific connection manner of the first connection portion 43a ' and the second connection portion 43b ' is the same as that of the first embodiment, and is not repeated herein. In contrast, in the present embodiment, at least a portion of the connecting element 43' is made of an elastic material so that the connecting element 43' itself can be elastically deformed, for example, at least a portion of the connecting element 43' is made of a plastic sheet, a thin metal sheet, and the like, and accordingly, the elastic element 500 for forcing the unlocking assembly 300 to reset can be omitted, the force-receiving element 41 is still provided with the force-receiving portion 411 for receiving the acting force and the position-limiting portion 413 for preventing the force-receiving element 41 from falling off the housing, and the position-limiting portion 413 is still connected to the force-receiving portion 411.

The second connection portion 43b ' in this embodiment is preferably in a movable connection manner, the first connection portion 43a ' is in a rigid connection manner, as shown in fig. 7, when the unlocking element 300 is at the first position, the locking element 200 is not in contact with the unlocking element 300, at this time, the unlocking element 300 is located substantially behind the locking element 200, and the movable element 42 is close to the force-receiving element 41 along the front-back direction, and the connection element 43' is curved, that is, the connection element 43' is curved in the initial state, when a force is applied to the force-receiving portion 411 from top to bottom, the force-receiving element 41 starts to move downward and immediately pulls the connection element 43' to elastically deform, as shown in fig. 7, along the front-back direction, when the connection element 43' deforms to the maximum amount, and the force-receiving element 41 continues to move downward, the downward force starts to be transmitted to the movable element 42 through the connection element 43', and forces the movable element 42 to move forward by the first distance g1, and the unlocking element 300 moves from the first position to the second position, and the movable element 41 is away from the front-back direction, and the locking element 200 rotates to the above the rotation axis L, and is supported by the ink cartridge 42, and can be taken out; as in the first embodiment, when the unlocking assembly 300 is located at the first position, the certain point/specific point of the lifting surface 422 of the present embodiment (for example, the front end point of the lifting surface 422 is selected) has a first projected point on the locking member 200 along the up-down direction, and when the unlocking assembly 300 is located at the second position, the certain point/specific point of the lifting surface 422 has a second projected point on the locking member 200 along the up-down direction, and the relative position between the first projected point and the second projected point, the position of the first projected point relative to the rotation axis L or the housing, and the position of the second projected point relative to the rotation axis L or the housing along the front-back direction are the same as those of the first embodiment. When the force from the top to the bottom is removed, the restoring force of the connecting member 43 'forces the force-receiving member 41 to move upward, and at the same time, the connecting member 43' pulls the movable member 42 to move backward, and finally, the unlocking assembly 300 returns to the first position from the second position to be reset.

In the process that the connecting member 43' converts the acting force from top to bottom to the acting force/pushing force from back to front, the second connecting portion 43b ' is movably connected, so that the connecting member 43' can be angularly adjusted relative to the movable member 42, so that the acting force can be more smoothly transmitted to the movable member 42; because the connecting piece 43 'has elasticity, in the process of transmitting the acting force from the force-bearing piece 41 to the connecting piece 43', even if the two pieces are rigidly connected, the connecting piece 43 'can ensure the smooth transmission of the acting force between the two pieces by adjusting the angle of the connecting piece 43' per se; it is understood that the first connection portion 43a 'may also be in an articulated manner, in which the acting force can be delayed in the process of being transmitted from the force-bearing member 41 to the connection portion 43', and in the action mechanism 400 in which the first connection portion 43a 'is in the articulated manner, under the condition that the connection portion 43' has the same deformation amount, the distance g of forward movement of the movable member 42 will be shortened, or in other words, under the condition that the distance g of forward movement of the movable member 42 is ensured to be unchanged, the distance of downward movement of the force-bearing member 41 will be increased, and this structure is more advantageous for the ink cartridge in which the requirement for the forward movement distance of the movable member 42 is smaller or the requirement for the downward movement distance of the force-bearing member 41 is larger.

For simplicity, the same components in this embodiment as those in the previous embodiment are numbered the same, and as shown in fig. 8, the unlocking assembly 300 is detachably installed in the ink cartridge 100, and includes an acting mechanism 600, a first elastic member 500, and a second elastic member 501, the acting mechanism 600 is used for receiving acting force and unlocking the locking surface 203 from the position-limiting surface 105, and the first elastic member 500 and the second elastic member 501 are used for forcing the acting mechanism 600 to reset.

As shown in fig. 9, the action mechanism 600 in this embodiment includes a force receiving element 61, a movable element 62, and a force conversion element disposed between the force receiving element 61 and the movable element 62, in this embodiment, the force conversion element includes a first magnetic element 615 and a second magnetic element 625, wherein the force receiving element 61 is configured to receive a downward acting force, the force receiving element 61 includes a force receiving portion 611, a first elastic element combining portion 612 and a limiting portion 613 connected to the force receiving portion 611, and a first magnetic element 615 disposed in the force receiving element 61, the force receiving portion 611 is further provided with a rib 614 for increasing a friction force, the limiting portion 613 is combined with the housing and configured to prevent the force receiving element 61 from falling off the housing and limit a movement direction of the force receiving element 61 to an up-down direction, and the first magnetic element 615 is configured to interact with the second magnetic element 625 to force the movable element 62 to move in a forward-backward direction, thereby releasing locking between the locking surface 203 and the limiting surface 105. Preferably, the first elastic member 500 is coupled to the force receiving member 61, one end of the first elastic member 500 abuts against the first elastic member coupling portion 612, and the other end abuts against the housing, so that the biasing force of the first elastic member 500 can be more directly applied to the force receiving member 61 in the process of returning the biasing mechanism 600.

The movable member 62 includes a main body 621, a lifting surface 622 extending from the main body 621, a holding surface 623 disposed adjacent to the lifting surface 622, a second elastic member coupling portion 624 coupled to the main body 621, and a second magnetic member 625 disposed in the main body 621, and the first magnetic member 615 and the second magnetic member 625 are disposed in a staggered manner in the up-down direction and/or the left-right direction, for example, in the up-down direction, the second magnetic member 625 is below the first magnetic member 615, and in the left-right direction, the second magnetic member 625 is left/right of the first magnetic member 615, and at this time, the unlocking assembly 300 is in the first position, and the locking member 200 does not contact with the unlocking assembly 300. The magnetic force between the first magnetic element 615 and the second magnetic element 625 can force the movable element 62 to move in the front-back direction, so that the movable element 62 and the force-receiving element 61 can not be in contact with each other, thereby reducing the friction force between the movable element 62 and the force-receiving element 61, reducing the abrasion between the movable element 62 and the force-receiving element 61, and prolonging the service life.

In this embodiment, the magnetic poles of the second magnetic member 625 on the opposite side of the first magnetic member 615 are the same, and before the force receiving member 61 receives a downward acting force, the movable member 62 and the force receiving member 61 approach each other in the front-rear direction, so that when the force receiving member 61 receives a downward acting force and moves downward, the first magnetic member 615 and the second magnetic member 625 oppose each other, a repulsive force in the front-rear direction is generated between the first magnetic member 615 and the second magnetic member 625, the force receiving member 61 and the movable member 62 move away from each other in the front-rear direction, the second magnetic member 625 drives the movable member 62 to move forward in the front-rear direction under the repulsive force, the lifting surface 622 lifts the locking member 200 so that the locking member 200 rotates around the rotation axis L as a whole, when the locking member 200 reaches above the movable member 62 as a whole, the locking member 200 is held by the holding surface 623, the locking surface 203 and the stopper surface 105 are unlocked, the ink cartridge 100 can be taken out smoothly, and at this time, the unlocking member 300 is in the second position; as in the first embodiment, when the unlocking assembly 300 is located at the first position, a certain point/specific point of the lifting surface 622 of this embodiment (for example, a front end point of the lifting surface 622 is selected) has a first projected point on the locking member 200 along the up-down direction, and when the unlocking assembly 300 is located at the second position, the certain point/specific point of the lifting surface 622 has a second projected point on the locking member 200 along the up-down direction, and along the front-back direction, the relative position between the first projected point and the second projected point, the position of the first projected point relative to the rotation axis L or the housing, and the position of the second projected point relative to the rotation axis L or the housing are the same as those of the first embodiment.

In other embodiments, before the force-receiving member 61 receives a downward force, the movable member 62 and the force-receiving member 61 are away from each other in the front-rear direction, for example, the movable member 62 is located in front of the locking member 200, and the magnetic poles of the opposite sides of the first magnetic member 615 and the second magnetic member 625 are opposite, so that when the force-receiving member 61 receives the downward force and moves downward, an attraction force in the front-rear direction is generated between the first magnetic member 615 and the second magnetic member 625, the force-receiving member 61 and the movable member 62 approach each other in the front-rear direction, and the second magnetic member 625 drives the movable member 62 to move backward in the front-rear direction under the action of the attraction force, so as to lift up the locking member 200, so that the locking between the locking surface 203 and the limiting surface 105 is released, and the ink cartridge 100 can be taken out smoothly.

The lifting surface 622 may be a plane parallel to the up-down direction, or an inclined surface inclined with respect to the up-down direction, and the lifting surface on the inclined surface is relatively more labor-saving, so that the lifting surface 622 is preferably an inclined surface, the front side of the lifting surface 622 is closer to the housing/main body 621 than the rear side thereof along the front-rear direction, and an included angle formed between the lifting surface 622 and the rear direction is an acute angle, and the smaller the included angle, the smoother the movement of the movable member 62. The second elastic member 501 is coupled to the movable member 62, one end of the second elastic member 501 abuts against the second elastic member coupling portion 624, and the other end abuts against the limiting surface 105, so that the acting force of the second elastic member 501 can reset the movable member 62 to the first position in the resetting process of the acting mechanism 600.

Fig. 10 shows the comparison of the relative positions of the force-receiving member 61, the movable member 62, the first magnetic member 615 and the second magnetic member 625 before and after the force is transmitted to the actuating mechanism 600, wherein the force-receiving member 61 is limited to move only in the up-down direction, and the movable member 62 is limited to move only in the front-back direction, so that the force applied from the top to the bottom by the force-receiving member 61 is converted into a force for forcing the movable member 62 to move forward by the repulsive force of the first magnetic member 615 and the second magnetic member 625. When the force from the top to the bottom is applied, the force receiving member 61 moves downward in the up-down direction, the first elastic member 500 is compressed and deformed, and meanwhile, the first magnetic member 615 moves downward together with the force receiving member 61, and in the front-back direction, the repulsive force between the first magnetic member 615 and the second connecting member 625 pushes the movable member 62 to move forward in the front-back direction, the second elastic member 501 is compressed and deformed, so that the movable member 62 is forced to move forward by the first distance g1, and the unlocking assembly 300 moves from the first position to the second position. Once the acting force from top to bottom is removed, the stressed member 61 is reset upwards under the elastic reset force of the first elastic member 500, and meanwhile, the movable member 62 is reset backwards under the elastic reset force of the second elastic member 501, and the unlocking assembly 300 is returned to the first position from the second position.

For simplicity, the same parts in this embodiment as those in the above embodiment are numbered the same, and as shown in fig. 17, the unlocking assembly 300 is detachably installed in the ink cartridge 100, and includes an acting mechanism 900, and the acting mechanism 900 is used for receiving acting force and unlocking the locking surface 203 from the limiting surface 105.

As shown in fig. 18, the acting mechanism 900 in this embodiment includes the force receiving element 91 and the movable element 92, in this embodiment, there is no connecting portion/magnetic element between the force receiving element 91 and the movable element 92, the force conversion element is at least a portion of the movable element 92 itself, and the force receiving element 91 is not provided with a limiting portion, so that the volume of the unlocking assembly 300 can be reduced.

As shown in fig. 17, in the present embodiment, the ink cartridge 100 further includes a guide portion 109 provided on the housing, and when viewed from left to right, the guide portion 109 has an arc-shaped groove-like structure, and is configured to cooperate with the unlocking portion 921 to move the unlocking portion 921 along the guide portion 109, and at the same time, the guide portion 109 also functions to hold the action mechanism 900 in the ink cartridge 100, specifically, the movable member 92 is held by the arc-shaped guide portion 109.

The movable member 92 may be formed integrally with/separately from the force receiving member 91, and when the force receiving member 91 and the force receiving member are integrally formed, the acting force received by the force receiving member 91 can be transmitted to the movable member 92 more quickly and efficiently, and when the force receiving member 91 is pressed, the unlocking portion 921 is pushed to move forward and upward along the guide portion 109, and the contact portion 922 moves upward and abuts against the locking member 200, so that the locking member 200 is integrally rotated around the rotation axis L, and the locking member 200 is lifted, and the locking of the locking surface 203 and the stopper surface 105 is released, and the ink cartridge 100 can be smoothly taken out.

When the ink cartridge 100 is mounted to the inkjet printer, the locking member 200 rotates around the rotation axis L, the locking member 200 falls, the locking surface 203 abuts against the limiting surface 105, the unlocking assembly 300 is located at the first position, the ink cartridge 100 is locked, at this time, the distance between the contact portion 922 and the upper end of the limiting surface 105 is h1, the value of the distance h1 is greater than or equal to 0, and the distance between the force-bearing member 91 and the upper side plate 106 is h2 in the vertical direction; when a downward acting force is applied, the force receiving member 91 pushes the movable member 92 to move forward and upward along the guide portion 109, the contact portion 922 moves upward and abuts against the locking member 200, the locking member 200 is lifted, the locking between the locking surface 203 and the limiting surface 105 is released, the unlocking assembly 300 moves from the first position to the second position, the ink cartridge 100 is unlocked, at this time, the distance between the contact portion 922 and the upper end of the limiting surface 105 is h1', the distance between the force receiving member 91 and the upper side plate 106 is h2', h2' < h2, and the contact portion 922 moves upward by the second distance g2 in the up-down direction. The movable member 92 is guided by the guide portion 109 to move forward and upward, and accordingly, the contact portion 922 moves in the upward and downward direction, so that the movable member 92 functions as a force conversion member that converts the obliquely downward force applied to the force receiving member 91 into a force that urges the movable member 92 forward.

The action mechanism 900 may further include a limiting portion 923 connected to the force-receiving member 91 and/or the movable member 92, where the limiting portion 923 may be configured to prevent the force-receiving member 91 and/or the movable member 92 from falling off the housing; further, the action mechanism 900 may also eliminate the elastic return member, and at this time, the volume of the unlocking assembly 300 is further reduced, thereby contributing to the overall miniaturization of the ink cartridge 100; it will be appreciated that when the actuating mechanism 900 is provided with a resilient return member, preferably the resilient return member will abut the spacing portion 923.

In this embodiment, when the unlocking assembly 300 is in the first position, the distance h2 between the force-receiving member 91 and the upper side plate 106 is greater than the distance h1 between the contact portion 922 and the upper end of the limiting surface 105, so that when the force-receiving portion 911 is pressed downward, there is enough space for the contact portion 922 to lift the locking member 200 upward and to pass over the upper end of the limiting surface 105, so that the locking between the locking surface 203 and the limiting surface 105 is released.

In this embodiment, the weight of the force receiving member 91 may be larger than the weight of the movable member 92, or may be smaller than the weight of the movable member 92.
