The acting mechanism 400 includes a force-bearing member 41, a movable member 42, and a force conversion member connecting the force-bearing member 41 and the movable member 42. In this embodiment, the force conversion member is a connecting member 43, wherein the force-bearing member 41 is used to receive the force-bearing member 41.

FIG. 5 is a comparison diagram of the state of the action mechanism according to the first embodiment of the present invention before being applied with force and after being applied with force.

A first connecting portion 43a is formed between the connecting member 43 and the force-receiving member 41, and a second connecting portion 43b is formed between the connecting member 43 and the movable member 42, wherein at least the second connecting portion 43b is an active connection, such as connecting The connection between the piece 43 and the movable piece 42 is made by at least one way, such as a spring connection, a connection that can rotate around a fixed pin, or a connection through a flexible material, so that the connection piece 43 is movable relative to the movable piece 42, and the connection piece 43 also The acting force can be transmitted to the movable member 42 through the second connecting portion 43b. The connection method of the first connection portion 43a is not limited, that is to say, the connection member 43 and the force receiving member 41 may be connected in a rigid manner in a fixed manner, or the same connection method as the second connection portion 43b may be adopted. In an example, the connecting piece 43 itself is made of an inflexible material so that the connecting piece 43 will not be elastically deformed, and the loss of the force in the transmission process through the connecting piece 43 can be reduced, and then, the acting force will pass through the second connection. In the process that the part 43b is transmitted from the connecting piece 43 to the moving piece 42, even if the relative position between the connecting piece 43 and the moving piece 42 is not conducive to the transmission of the force, under the action of the force, the connecting piece 43 can be relative to the moving piece 43. The member 42 moves at an angle, so that the connecting member 43 reaches a position that is more favorable for transmitting the force to the movable member 42 .

When the connection member 43 and the force-receiving member 41 are rigidly connected, as described above, since the second connection portion 43b between the connection member 43 and the movable member 42 is movably connected, the connection member 43 can be relatively The movable member 42 is moved to a position conducive to transmitting the force; when the connecting member 43 and the force-receiving member 41 are also movably connected, it is understandable that after the connecting member 43 has moved an angle relative to the movable member 42, even if the connection is The member 43 is still in a position that is not conducive to the transmission of the force relative to the movable member 42, but the force can first force the connecting member 43 to move an angle relative to the force-bearing member 41, so that the force can be smoothly transmitted from the force-bearing member 41 to the force-bearing member 41. The connecting piece 43, and then the connecting piece 43 moves another angle relative to the moving piece 42, so that the force can be smoothly transmitted from the connecting piece 43 to the moving piece 42. It can be seen that the first connecting part 43a and the second connecting part 43a are connected When the parts 43b are all set in an articulating manner, the force applied to the force-receiving member 41 from top to bottom is more easily transmitted to the movable member 42 .

Figure 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. The force-receiving member 41 is restricted to move only in the up and down direction, and the movable member 42 Restricted to move only in the front and rear directions, therefore, the connecting member 43 acts as a force conversion member, which plays the role of converting the upward-downward force received by the force-receiving member 41 into a force that forces the movable member 42 to move forward. . When the force from top to bottom is applied, the force receiving member 41 moves downward in the up and down direction, the elastic member 500 is compressed and deformed, the connecting member 43 pushes the movable member 42 to move forward through the second connecting portion 43b, and at the same time, the first A connecting portion 43a moves downward together with the force-receiving member 41. Along the front-rear direction, the angle between the connecting member 43 and the rearward direction gradually decreases, and the upward-downward force is converted into a rear-to-forward force/ The push force forces the movable member 42 to move forward by a distance g, and the unlocking assembly 300 moves from the first position to the second position. 5, when the first connecting portion 43a is in a movable connection, in the second position, the smaller the included angle between the connecting member 43 and the rearward direction, the larger the distance g that the movable member 42 moves forward correspondingly. . Once the top-down force is removed, under the action of the elastic restoring force of the elastic member 500, the force-receiving member 41 is reset upward, and at the same time, the connecting member 43 pulls the movable member 42 to reset, and the unlocking assembly 300 returns from the second position to the first position. Location.

[Example 2]

FIG. 6 is a perspective view of the action mechanism involved in the second embodiment of the present invention; FIG. 7 is a state comparison diagram of the action mechanism involved in the second embodiment of the present invention before and after the force is applied.

For the sake of simplicity, the same components in this embodiment and the above-mentioned embodiments use the same numbers. As shown in FIG. 6 , the action mechanism 400 in this embodiment still includes a force receiving member 41, a movable member 42 and a force conversion member. In the embodiment, the force conversion member is the connecting member 43', which connects the force-bearing member 41 and the movable member 42, and the force-bearing member 41 is used to receive the downward force. In order to transmit the downward force to the movable member 42 , the movable member 42 is forced to move forward in the front-rear direction, and the locking between the locking surface 203 and the limiting surface 105 is released.

As shown in FIG. 6 , a first connecting portion 43a' is formed between the connecting member 43' and the force receiving member 41, and a second connecting portion 43b' is formed between the connecting member 43' and the movable member 42, wherein at least the second connecting portion 43b' is an active connection method, and the specific connection method of the first connection part 43a' and the second connection part 43b' is the same as that of the first embodiment, and will not be repeated here. The difference is that, in this embodiment, at least a part of the connecting member 43' is made of elastic material so that the connecting member 43' itself can be elastically deformed. Correspondingly, the elastic member 500 for forcing the unlocking assembly 300 to reset can be omitted, and the force-bearing member 41 is still provided with a force-bearing portion 411 for receiving the force and preventing the force-bearing member 41 from being removed from the housing. When the limiting portion 413 is dropped, the limiting portion 413 is still connected to the force-receiving portion 411 .

In this embodiment, the second connecting part 43b' is preferably in a flexible connection, and the first connecting part 43a' is in a rigid connection. As shown in FIG. 7, when the unlocking assembly 300 is in the first position, the connecting member 43' It is curved, that is to say, the connecting piece 43 ′ is curved in the initial state. When the force is applied to the force receiving part 411 from top to bottom, the force receiving part 41 starts to move downward and immediately pulls the connecting piece 43 . 'Elastic deformation occurs, as shown in Figure 7, when the connecting piece 43' is deformed to the maximum amount and the force receiving member 41 continues to move downward, the downward force begins to be transmitted to the movable piece 42 through the connecting piece 43', and forces the The movable member 42 moves forward by a distance g, and the unlocking assembly 300 moves from the first position to the second position. During this process, the locking member 200 is rotated as a whole around the rotation axis L to above the movable member 42, and is supported by the movable member 42. The ink cartridge 100 can be taken out. When the upward-downward force is withdrawn, the restoring force of the connecting piece 43' forces the force-receiving piece 41 to move upward, and at the same time, the connecting piece 43' pulls the movable piece 42 to move backward, and finally, the unlocking assembly 300 moves from the second position Return to the first position and reset.

During the process that the connecting piece 43' converts the upward-downward force to the backward-forward acting force/forcing force, the second connecting part 43b' is in a movable connection manner, so that the connecting piece 43' can be relatively movable relative to the The angle of the force-receiving member 42 is adjusted so that the force can be transmitted to the movable member 42 more smoothly; due to the elasticity of the connecting member 43', in the process of transmitting the force from the force-receiving member 41 to the connecting member 43', even if either of the two It is a rigid connection between the two, and the connecting piece 43' can also ensure the smooth transmission of the force between the two by adjusting its own angle; it can be understood that the first connecting part 43a' can also be flexibly connected. The force can be delayed in the process of being transmitted from the force-receiving member 41 to the connecting member 43'. In the case where the connecting member 43' has the same deformation amount, in the action mechanism 400 using the first connecting portion 43a' as a movable connection, The forward movement distance g of the movable member 42 will be shortened, or in other words, under the condition that the forward movement distance g of the movable member 42 is kept unchanged, the downward movement distance of the force receiving member 41 will increase. It can be seen that this structure is suitable for It is more favorable for an ink cartridge that requires a smaller forward movement distance of the movable member 42 or a larger downward movement distance of the force receiving member 41 .

Fig. 8 is a schematic diagram of a partial exploded view of the ink cartridge involved in the third embodiment of the present invention; Fig. 9 is a schematic diagram of the action mechanism involved in the third embodiment of the present invention; Fig. 10 is the action mechanism involved in the third embodiment of the present invention before a force is applied and the state comparison diagram after the applied force.

For the sake of simplicity, the same parts in this embodiment and the above-mentioned embodiments use the same numbers. As shown in FIG. 8 , the unlocking assembly 300 is detachably installed in the ink cartridge 100, including the action mechanism 600, the first elastic member 500 and the second elastic member 501, the acting mechanism 600 is used to receive the force and unlock the locking surface 203 and the limiting surface 105, and the first elastic member 500 and the second elastic member 501 are used to force the acting mechanism 600 to reset .

In this embodiment, the force conversion member includes a first magnetic member 615 and a second magnetic member 625, wherein the force receiving part 61 is used to receive the downward force, and the force receiving part 61 comprises a force receiving part 611, a first elastic part combining part 612 connected with the force receiving part 611, a limit part 613, and a In the first magnetic member 615 of the force-receiving member 61, the force-receiving portion 611 is also provided with a convex rib 614 for increasing the frictional force, and the limiting portion 613 is combined with the housing to prevent the force-receiving member 61 from falling off the housing. , and the movement direction of the force receiving member 61 is limited to the up and down direction. The first magnetic member 615 is used to interact with the second magnetic member 625 to force the movable member 62 to move along the front and rear directions, thereby releasing the locking surface 203 and the limiting surface 105 lock. Preferably, the first elastic member 500 is combined with the force-receiving member 61 , one end of the first elastic member 500 is in contact with the first elastic member coupling portion 612 , and the other end is in contact with the housing. During the reset process of the action mechanism 600 , The acting force of the first elastic member 500 can act on the force receiving member 61 more directly.

The movable member 62 includes a main body 621 , a lifting surface 622 extending from the main body 621 , a holding surface 623 arranged adjacent to the lifting surface 622 , a second elastic member coupling portion 624 connected with the main body 621 , and a second magnetic member provided in the main body 621 . The first magnetic piece 615 and the second magnetic piece 625 are dislocated along the up-down direction and/or the left-right direction. For example, in the up-down direction, the second magnetic piece 625 is below the first magnetic piece 615 in the left-right direction. , the second magnetic member 625 is on the left/right of the first magnetic member 615 , and at this time, the unlocking assembly 300 is in the first position. The magnetic force between the first magnetic member 615 and the second magnetic member 625 can force the movable member 62 to move in the front-rear direction, so that there is no contact between the movable member 62 and the force-receiving member 61, so that the movable member 62 can be reduced in size. The friction with the force-receiving member 61 reduces the wear between the movable member 62 and the force-receiving member 61 and prolongs the service life.

In this embodiment, the magnetic poles on the opposite side of the second magnetic member 625 and the first magnetic member 615 are the same. Before the force-receiving member 61 receives a downward force, the movable member 62 and the force-receiving member 61 approach each other in the front-rear direction. Therefore, when the force receiving member 61 is subjected to a downward force and moves downward, the first magnetic member 615 and the second magnetic member 625 are opposite to each other, and a frictional force in the front-rear direction is generated between the first magnetic member 615 and the second magnetic member 625 .
