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 connecting member 43 connecting the force receiving member 41 and the movable member 42 , wherein the force-bearing part 41 is used to receive the downward force, and the connecting part 43 is used as a force conversion part for transmitting the downward force to the movable part 42, forcing the movable part 42 to move forward along the front-rear direction, and then Release the locking of the locking surface 203 and the limiting surface 105. Preferably, the elastic member 500 is combined with the force receiving member 41. During the reset process of the action mechanism 400, the active force of the elastic member 500 can act more directly on the force receiving member 41 , as shown in Figure 3, the force receiving part 41 includes a force receiving part 411 and an elastic member joint part 412 connected with the force receiving part 411 and a limiting part 413, and the force receiving part 411 is also provided with a protrusion for increasing the friction force. Rib 414, one end of the elastic member 500 is in contact with the elastic member joint 412, the other end is in contact with the housing, and the limit portion 413 is combined with the housing to prevent the force-bearing member 41 from falling off from the housing, and will be stressed The movement direction of the member 41 is defined as the up and down direction.

The movable member 42 includes a main body 421 , a lifting surface 422 extending from the main body 421 , and a holding surface 423 arranged adjacent to the lifting surface 422 . As shown in Fig. 4A and Fig. 4B, when the movable part 42 does not receive the force, the locking surface 203 abuts against the limit surface 105, and the locking part 200 is not in contact with the unlocking assembly 300. At this time, the unlocking assembly 300 is approximately in the locking 200 behind and in the first position, along the vertical direction, a certain point/specific point A of the lifting surface 422 (can be any point on the lifting surface, such as the front end point of the lifting surface) has a first projected point on the locking piece 200 B, preferably, along the front-to-back direction, the first projected point B is located between the locking surface 203/limiting surface 105 and the rotation axis L; when the movable part 42 receives the force, the main body 421 moves forward on the housing, The lifting surface 422 lifts the locking piece 200, so that the locking piece 200 rotates around the rotation axis L as a whole. When the locking piece 200 reaches the top of the movable piece 42 as a whole, the locking piece 200 is held by the holding surface 423, and the locking surface 203 and the limiting surface 105 The lock is released, and the ink cartridge 100 can be taken out smoothly. At this time, the unlocking assembly 300 is in the second position. Along the up and down direction, a certain point/specific point A of the lifting surface 422 has a second projection point C on the locking member 200, along the In the front-to-back direction, the second projection point C is located between the locking surface 203/limiting surface 105 and the rotation axis L, and the second projection point C is located in front of the first projection point B, or in other words, the second projection point C is larger than the first projection point C. The projection point B is farther away from the rotation axis L, or in other words, the second projection point C is closer to the limiting surface 105/locking surface 203 than the first projection point B, that is to say, when the ink cartridge 100 needs to be unlocked, the unlocking assembly 300 A force is applied to the locking member 200 at a position away from the rotation axis L or at a position close to the locking surface 203/limiting surface 105, so that the locking member 200 can be pushed and rotated more easily, and the ink cartridge 100 can be released more easily. locking. The lifting surface 422 can be a plane parallel to the up-down direction, or an inclined surface inclined relative to the up-down direction. Relatively speaking, the lifting surface that is an inclined surface is more labor-saving. Therefore, the lifting surface 422 is preferably an inclined surface, and its inclination direction is , along the front-to-back direction, the front of the lifting surface 422 is closer to the housing/main body 421 than the rear, and the angle formed between the lifting surface 422 and the rearward direction is an acute angle, the smaller the angle, the faster the movement of the movable part 42 Smoothly; preferably, the casing is provided with a guide portion 107 extending in the front-rear direction, and the guide portion 107 is in the shape of a groove for guiding the main body 421, so that the movement track of the movable member 42 can be determined.

Fig. 5 is a comparison diagram of the state of the action mechanism according to Embodiment 1 of the present invention before and after being applied with an action force.

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

When it is rigidly connected between the connecting piece 43 and the force receiving member 41, as mentioned above, because the second connecting portion 43b between the connecting piece 43 and the movable piece 42 is in a movably connected manner, therefore, the connecting piece 43 can be relatively The movable part 42 moves to a position that facilitates the transmission of active force; when the connecting part 43 and the force receiving part 41 are also flexibly connected, it can be understood that after the connecting part 43 has moved an angle relative to the movable part 42, even if the connection 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 receiving member 41, so that the force can be smoothly transmitted from the force receiving member 41 to The connecting part 43, and then the connecting part 43 moves another angle relative to the movable part 42, so that the active force can be smoothly transmitted from the connecting part 43 to the movable part 42. It can be seen that the first connecting part 43a and the second connecting part 43a When the parts 43b are arranged in an articulated 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-back direction, therefore, the connecting piece 43, as a force conversion piece, plays the role of converting the upper and lower active force received by the force receiving member 41 into an active force that forces the movable member 42 to move forward. . Before the force is applied to the force receiving member 41, the movable member 42 is close to the force receiving member 41 along the front and rear directions. Being compressed and deformed, the connecting part 43 pushes the movable part 42 to move forward through the second connecting part 43b. At the same time, the first connecting part 43a and the force receiving part 41 move downward together. The included angle gradually decreases, and the force from top to bottom is converted into force/forced thrust from back to front, forcing the movable part 42 to move forward by the first distance g1, and the unlocking assembly 300 moves from the first position to the second position. Position, at this time, along the front-to-back direction, the movable member 42 is far away from the force-bearing member 41 . It can be seen from FIG. 5 that when the first connecting part 43a is in a flexible connection mode, in the second position, the smaller the angle between the connecting part 43 and the backward direction, the greater the distance g that the movable part 42 moves forward. . Once the force from top to bottom is cancelled, under the action of the elastic restoring force of the elastic member 500, the stressed member 41 is reset upwards, 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 according to the second embodiment of the present invention; Fig. 7 is a comparative view of the state of the action mechanism according to the second embodiment of the present invention before and after being applied with an action force.

For the sake of brevity, the same parts in this embodiment and the above-mentioned embodiments use the same numbers, as shown in Figure 6, the action mechanism 400 in this embodiment still includes a force-bearing part 41, a movable part 42 and a force conversion part. In the embodiment, the force conversion part is a connecting part 43', and the connecting part 43' connects the force receiving part 41 and the movable part 42, and the force receiving part 41 is used to receive the downward force, and the connecting part 43' is used as a force conversion part. In order to transmit the downward active force to the movable part 42, the movable part 42 is forced to move forward along the front-rear direction, and the lock between the locking surface 203 and the limiting surface 105 is released; the movable part in this embodiment also includes a main body 421, from the main body A lifting surface 422 extending from 421 and a retaining surface 423 arranged adjacent to the lifting surface 422 .

As shown in Figure 6, the first connecting part 43a' is between the connecting part 43' and the force receiving part 41, and the second connecting part 43b' is between the connecting part 43' and the movable part 42, wherein at least the second connecting part 43b' is a flexible connection, and the specific connection between the first connection part 43a' and the second connection part 43b' is the same as that in Embodiment 1, and will not be repeated here. The difference is that in this embodiment, at least a part of the connector 43' is made of elastic material so that the connector 43' itself can be elastically deformed, for example, at least a part of the connector 43' is made of a plastic sheet, a thin metal sheet Correspondingly, the elastic member 500 used to force the unlocking assembly 300 to reset can be omitted, and the force-bearing member 41 is still provided with a force-receiving part 411 for receiving the force and for preventing the force-receiving member 41 from the casing. The detached limiting portion 413 is still connected to the force-receiving portion 411 .

The second connecting part 43b' in this embodiment is preferably in the form of flexible connection, and the first connecting part 43a' is in the form of rigid connection. As shown in FIG. 7, when the unlocking assembly 300 is in the first position, the locking member 200 is In contact with the unlocking assembly 300, at this time, the unlocking assembly 300 is roughly located behind the locking member 200, along the front-to-back direction, the movable member 42 is close to the force receiving member 41, and the connecting member 43' is curved, that is to say, the connecting member 43' is in the The initial state is curved. 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 part 43' to undergo elastic deformation. As shown in Figure 7, along the front and rear direction, when the connecting piece 43' is deformed to the maximum amount, and when the force-receiving piece 41 continues to move downward, the downward force starts to be transmitted to the movable piece 42 through the connecting piece 43', and forces the movable piece 42 to move forward a first distance g1, the unlocking assembly 300 moves from the first position to the second position, and the movable part 42 moves away from the force receiving part 41 along the front-back direction. Supported by the movable part 42, the ink cartridge 100 can be taken out; as in the first embodiment, when the unlocking assembly 300 is in the first position, along the up and down direction, a certain point/specific point of the lifting surface 422 of this embodiment (for example, selecting the lifting surface 422 front end point) has a first projection point on the locking member 200, when the unlocking assembly 300 is in the second position, along the up and down direction, a certain point/specific point of the lifting surface 422 has a second projection point on the locking member 200 , along the front-to-back direction, the relative position between the first projection point and the second projection point, the position of the first projection point relative to the rotation axis L or the housing, and the position of the second projection point relative to the rotation axis L or the housing The positions are all the same as in Embodiment 1. When the force from up to down is cancelled, the restoring force of the connecting part 43' forces the stressed part 41 to move upwards, and at the same time, the connecting part 43' pulls the movable part 42 to move backward, and finally, the unlocking assembly 300 moves from the second position Return to the first position and reset.

In the process that the connecting part 43' converts the force from up to down to the force/force from back to front, the second connecting part 43b' is in a flexible connection mode, so that the connecting part 43' can move relative to the The angle of the member 42 is adjusted so that the active force can be transmitted to the movable member 42 more smoothly; since the connecting member 43' itself has elasticity, in the process of the force being transmitted from the force receiving member 41 to the connecting member 43', even if the force between the two The connection between them is rigid, and the connecting part 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 connected in a flexible manner. The force can be delayed in the process of being transmitted from the force-receiving part 41 to the connecting part 43'. Under the condition that the connecting part 43' has the same deformation amount, in the action mechanism 400 using the first connecting part 43a' as a flexible connection, The distance g that the movable part 42 moves forward will be shortened, or in other words, under the condition that the distance g that the movable part 42 moves forward is constant, the distance that the force-bearing part 41 moves downward will increase. It can be seen that this structure is for It is more favorable for the movable member 42 to move forward with a smaller distance or the force receiving member 41 to move downward with a larger distance.

Preferably, the first elastic member 500 is combined with the force-receiving member 61, one end of the first elastic member 500 abuts against the first elastic member joint portion 612, and the other end abuts against 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 part 62 includes a main body 621 , a lifting surface 622 extending from the main body 621 , a retaining surface 623 arranged adjacent to the lifting surface 622 , a second elastic member coupling part 624 connected to the main body 621 and a second magnetic element disposed in the main body 621 . 625, along the up-down direction and/or the left-right direction, the first magnetic part 615 and the second magnetic part 625 are misplaced, for example, along the up-down direction, the second magnetic part 625 is below the first magnetic part 615, along the left-right direction, The second magnetic member 625 is on the left/right of the first magnetic member 615 . At this time, the unlocking assembly 300 is in the first position, and the locking member 200 is not in contact with the unlocking assembly 300 . The magnetic force between the first magnetic part 615 and the second magnetic part 625 can force the movable part 62 to move along the front-back direction, thus, there can be no contact between the movable part 62 and the force receiving part 61, thereby reducing the size of the movable part 62. The frictional force between the movable part 62 and the force receiving part 61 reduces the abrasion between the movable part 62 and the force receiving part 61 and prolongs the service life.

In this embodiment, the magnetic poles on the opposite side of the second magnetic part 625 and the first magnetic part 615 are the same, and before the force receiving part 61 receives a downward force, the movable part 62 and the force receiving part 61 are close to each other in the front and back direction, Therefore, when the force-bearing member 61 is subjected to a downward force and moves downward, the first magnetic member 615 is opposite to the second magnetic member 625, and a force along the front-rear direction is generated between the first magnetic member 615 and the second magnetic member 625. Repulsive force, the force receiving part 61 and the movable part 62 are far away from each other in the front-rear direction, the second magnetic part 625 drives the movable part 62 to move forward along the front-rear direction under the action of the repulsive force, and the lifting surface 622 lifts the locking part 200, Make the lock piece 200 rotate around the rotation axis L as a whole. When the lock piece 200 reaches the top of the movable piece 62 as a whole, the lock piece 200 is held by the holding surface 623, the lock between the lock surface 203 and the limit surface 105 is released, and the ink cartridge 100 can be smoothly moved. At this time, the unlocking assembly 300 is in the second position; as in the first embodiment, when the unlocking assembly 300 is in the first position, along the up and down direction, a certain point/specific point of the lifting surface 622 of this embodiment (for example, select The front end point of the lifting surface 622) has a first projected point on the locking member 200. When the unlocking assembly 300 is in the second position, along the up and down direction, a certain point/specific point of the lifting surface 622 has a second projected point on the locking member 200. Projection points, along the front-to-back direction, the relative position between the first projection point and the second projection point, the position of the first projection point with respect to the rotation axis L or the shell, and the second projection point with respect to the rotation axis L or the shell The position of body is all identical with embodiment one.

Therefore, when the force-bearing piece 61 is subjected to a downward force and moves downward, a force along the front-back direction is generated between the first magnetic piece 615 and the second magnetic piece 625. Attractive force, the force receiving part 61 and the movable part 62 are close to each other in the front-rear direction, and the second magnetic part 625 drives the movable part 62 to move backward along the front-rear direction under the action of the attractive force, and the locking part 200 is lifted to make the locking surface The locking between 203 and the limiting surface 105 is released, and the ink cartridge 100 can be taken out smoothly.

The lifting surface 622 can be a plane parallel to the up and down direction, or an inclined surface inclined relative to the up and down direction. Relatively speaking, the lifting surface that is an inclined surface is more labor-saving. Therefore, the lifting surface 622 is preferably an inclined surface, and its inclination direction is, along In the front-rear direction, the front of the lifting surface 622 is closer to the housing/main body 621 than the rear, and the angle formed between the lifting surface 622 and the rearward direction is an acute angle. The smaller the angle, the smoother the movement of the movable member 62 . The second elastic member 501 is combined with the movable member 62, and one end of the second elastic member 501 abuts against the joint part 624 of the second elastic member, and the other end abuts against the limiting surface 105. During the reset process of the action mechanism 600, the second The force of the elastic member 501 can reset the movable member 62 to the first position.

Figure 10 shows before and after the force is transmitted to the action mechanism 600, 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, the force receiving member 61 is restricted It can only move in the up and down direction, and the movable part 62 is restricted and can only move in the front and rear directions. Therefore, the force from up to down on the force receiving part 61 is transformed by the repulsive force of the first magnetic part 615 and the second magnetic part 625. is the active force that forces the movable part 62 to move forward. When the force from top to bottom is applied, the force receiving member 61 moves downward along the up and down direction, and the first elastic member 500 is compressed and deformed. At the same time, the first magnetic member 615 moves downward together with the force receiving member 61 along the In the front-to-back direction, the repulsive force between the first magnetic part 615 and the second connecting part 625 pushes the movable part 62 to move forward along the front-to-back direction, and the second elastic part 501 is compressed and deformed, forcing the movable part 62 to move forward by a first distance g1 , the unlocking assembly 300 moves from the first position to the second position. Once the force from top to bottom is cancelled, under the action of the elastic restoring force of the first elastic member 500, the stressed member 61 is reset upwards, and at the same time, under the action of the elastic restoring force of the second elastic member 501, the movable member 62 moves backward. Reset, the unlocking assembly 300 returns from the second position to the first position.

As shown in Figure 18, the action mechanism 900 in this embodiment includes a force-bearing part 91 and a movable part 92. In this embodiment, there is no connecting part/magnetic part between the force-bearing part 91 and the movable part 92, and the force conversion part is At least a part of the movable part 92 itself, and the force receiving part 91 is not provided with a limiting part, the volume of the unlocking assembly 300 can be reduced. The force receiving member 91 is used to receive the downward force. The force receiving member 91 includes a force receiving portion 911. The force receiving portion 911 is also provided with a convex rib 912 for increasing friction. The movable member 92 includes an unlocking portion 921 and a The contact part 922 at the end of the unlocking part 921, the movable part 92 has an arc shape matching the shape of the guide part 109, therefore, the movable part 92 has an inner side 92a facing the center of the arc and an outer side 92b away from the center of the arc. Among them, the unlocking part 921 can be made of elastic material, such as rubber, spring, etc., or can be made of non-elastic material. As shown in Figure 17, in this embodiment, the ink cartridge 100 also includes a guide part 109 arranged on the housing, and when viewed from left to right, the guide part 109 is an arc-shaped groove structure for unlocking and unlocking. Part 921 cooperates to make the unlocking part 921 move along the guide part 109. At the same time, the guide part 109 also plays the role of keeping the action mechanism 900 in the ink cartridge 100. Specifically, the movable part 92 is guided by the arc guide part 109. clamping.

When the two are integrally formed, the force received by the force receiving part 91 can be transmitted to the movable part 92 faster and more efficiently. When pressing the force receiving part 91 , the unlocking part 921 is pushed to move forward and upward along the guide part 109, the contact part 922 moves upward and abuts against the locking part 200, so that the locking part 200 rotates around the rotation axis L as a whole, thereby lifting the locking part 200 and locking The locking between the surface 203 and the limiting surface 105 is released, and the ink cartridge 100 can be taken out smoothly.

Figure 19A shows before and after the force is transmitted to the action mechanism 900, along the up and down direction, the comparison of the relative positions between the force receiving member 91 and the movable part 92, Figure 19B shows before and after the force is transmitted to the action mechanism 900, along the vertical direction The comparison of the relative positions between the force receiving member 91 and the movable member 92 in the front and back direction, FIG. 20A shows the relative position between the working mechanism 900 and the locking member 200 before the working force is transmitted to the working mechanism 900, and FIG. 20B shows After the action force is transmitted to the action mechanism 900, the relative position between the action mechanism 900 and the locking member 200 is determined.

After the ink cartridge 100 is installed in 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 in the first position, and the ink cartridge 100 is locked. , along the up and down direction, 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 receiving member 91 and the upper side plate 106 is h2; when When the downward force is applied, the force receiving part 91 pushes the movable part 92 to move forward and upward along the guide part 109, and the contact part 922 moves upward and abuts against the locking part 200, lifts the locking part 200, and locks The locking between the surface 203 and the limiting surface 105 is released, the unlocking assembly 300 moves from the first position to the second position, and the ink cartridge 100 is unlocked. The distance 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 a second distance g2. The movable part 92 is guided by the guide part 109 to move forward and upward, and correspondingly, the contact part 922 moves in the up and down direction. Therefore, the movable part 92, as a force conversion part, plays the role of obliquely downward to the force receiving part 91. The force is converted into the action of a force forcing the movable member 92 forward.

The action mechanism 900 may also include a limiting part 923 connected with the force receiving part 91 and/or the movable part 92, and the limiting part 923 may be used to prevent the force receiving part 91 and/or the movable part 92 from falling from the casing; further, The action mechanism 900 can also cancel the elastic reset member. At this time, the volume of the unlocking assembly 300 is further reduced, thereby facilitating the overall miniaturization of the ink cartridge 100; understandably, when the action mechanism 900 is provided with an elastic return member, preferably, The elastic reset member will abut against the limiting portion 923 .

In this embodiment, when the unlocking assembly 300 is in the first position, the distance h2 between the force-bearing 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 pressing down When the force receiving portion 911 is in place, there is enough space for the contact portion 922 to lift the locking member 200 upwards and 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 greater than that of the movable member 92 or may be smaller than that of the movable member 92 .

The bottom moves forward and upward along the guide part 109, so that the contact part 922 moves upward, close to the plane where the upper end of the limit surface 105 is located. When the position is close, after the ink cartridge 100 is installed in the inkjet printer, the locking member 200 falls, the locking member 200 abuts against the contact portion 922, and presses the contact portion 922 downward, so that the unlocking assembly 300 starts from the second position. The state is switched to the first position. At this time, the active force has not been applied to the force receiving member 91. Along the up and down direction, a certain point/specific point P of the movable member 92 (for example, the point where the movable member 92/contact portion 922 is the farthest away from the force receiving member 71 end point) has a first projected point on the locking member 200, the ink cartridge 100 is locked, and the locking member 200 will be in contact with the unlocking assembly 300, wherein the specific point P will coincide with the first projected point; when pressing the force receiving part 911 downward , the locking part 200 is lifted, and the unlocking assembly 300 moves from the first position to the second position. At this time, along the up and down direction, the specific point P has a second projection point on the movable part 200, the ink cartridge 100 is unlocked, and the locking part 200 is still Contact will be maintained with the unlocking assembly 300, wherein the specific point P will coincide with the second projected point. As in the previous embodiment, along the front-to-back direction, the relative position between the first projection point and the second projection point, the position of the first projection point relative to the rotation axis L or the housing, and the second projection point relative to the rotation axis The position of L or the housing is the same as that of Embodiment 1.

When the weight of the force-bearing member 91 is less than the weight of the movable member 92, the force-receiving member 91 will face upward and away from the plane where the upper side plate 106 is located. Before the ink cartridge 100 is installed in the inkjet printer, the unlocking assembly 300 can be considered as being in the same position as The state at the first position is close. After the ink cartridge 100 is installed in the inkjet printer, the locking member 200 falls. At this time, the force has not been applied to the force receiving member 91.
