In some embodiments of the present invention, as shown in fig. 2, the first door hook 1 includes: the door comprises a first mounting part 11 and a first hook-shaped part 12, wherein the first mounting part 11 is connected with the door body 100, the first hook-shaped part 12 protrudes out of the door body 100, and the first hook-shaped part 12 can extend into the box body. When an operator drives the door body 100 to move close to the box body, the first door hook 1 moves towards the box body, the first hook part 12 extends into the box body, and the first hook part 12 moves to bring a preset position in the box body, so that the door body 100 is connected with the box body; when the door 100 is separated from the cabinet, the operator drives the door 100 to move away from the cabinet, and the first hook 12 is released from the cabinet. When the first hook 12 extends into the box, the first hook 12 contacts the driver 2, and the first hook 12 pushes the driver 2 to rotate in the first rotation direction.

It is to be understood that the first mounting portion 11 and the first hook portion 12 are simplified for convenience of describing the present invention, and do not indicate or imply that the first door hook 1 is a split structure, and thus, should not be construed as limiting the present invention. The first hook 12 may be connected to the first mounting portion 11 by welding, screwing, riveting, or the like, or alternatively, the two may be formed by integral processing.

In some embodiments of the present invention, the door lock device 1000 further comprises: the elastic part 5, one end of the elastic part 5 drives the piece 2 to link to each other, the other end of the elastic part 5 links to each other with the box, the driving piece 2 has the initial position that does not contact with the first door hook 1, when the driving piece 2 is in the initial position, the direction of the elasticity of the elastic part 5 is parallel with the line between one end of the elastic part 5 and the center of rotation of the driving piece 2.

The resilient member 5 is connected between the housing and the driver 2 so that when the driver 2 is rotated in the first rotational direction, the state of the resilient member 5 changes. When the driving member 2 is located at the initial position, the elastic direction of the elastic member 5 is parallel to the connection line between one end of the elastic member 5 and the rotating portion 23, i.e. the elastic member 5 is in a balanced state, and the elastic force of the elastic member 5 does not drive the driving member 2 to rotate in the first rotating direction, and does not drive the driving member 2 to rotate against the first rotating direction. When the driving member 2 is at the initial position, when the driving member 2 is not subjected to the action of an external force, the elastic force of the elastic member 5 on the driving member 2 enables the driving member 2 to be stably at the initial position; when the driving member 2 is subject to the external force action of closing the door, for example, when the door is rotated due to shaking, the elastic member 5 is also driven by the driving member 2 to deform and deviate from the balance state, and the elastic member 5 can return to the balance state under the elastic force action of itself, i.e., the driving member 2 is driven to return to the initial position. The utility model discloses elastic component 5 can make driving piece 2 resume initial position, receives when external force factors influence such as rocking at the box, and driving piece 2 can reply initial position automatically, avoids driving piece 2 to receive external influence and skew, and driving piece 2 keeps closing the door and preparing for door lock device 1000 at initial position.

Alternatively, after the driving member 2 is rotated in the first rotation direction from the initial position by a preset angle, the elastic member 5 is stretched to make the driving member 2 have a tendency to rotate in the first rotation direction.

For convenience of description, the position where the driving member 2 is rotated by a predetermined angle in the first rotation direction from the initial position is referred to as a reversing position in the door lock device 1000 of the present invention. When driving piece 2 is in the switching-over position, elastic component 5 that links to each other with driving piece 2 is stretched, elastic component 5 has the shrink trend, even driving piece 2 has along first direction of rotation pivoted trend of elastic force of elastic component 5, when driving piece 2 moves to the switching-over position promptly, elastic component 5 can drive driving piece 2 and rotate along first direction of rotation, the elastic force of elastic component 5 is driving piece 2 pivoted power this moment, elastic force can drive driving piece 2 and first door hook 1 and move to the box, this can receive the resistance of bolster 3 when the door body 100 is closed, but the resistance of driving force reduction bolster 3 of elastic component 5 to driving piece 2, make first door hook 1 can move the preset position in the box smoothly, in order to close door body 100.

Therefore the utility model discloses the motion process of driving piece 2 when closing the door can be divided into two parts, and the first part is for moving to the switching-over position from initial position, and the second part is for moving to the end position from the switching-over position. During the movement of the first part, the driving member 2 rotates in a first rotation direction, the driving member 2 drives the elastic member 5 to deviate from the equilibrium position, the elastic member 5 has a movement tendency to return to the equilibrium position, and therefore the driving member 2 is subjected to the resistance of the elastic member 5; during the second portion of the movement, the driving member 2 continues to rotate in the first rotation direction, and the driving member 2 contacts with the swinging member 4 and is thus resisted by the buffering member 3, but at this time, the driving member 2 is driven by the elastic member 5, and the door body 100 is more easily closed.

It can be understood that, when the driving element 2 moves to the reversing position, the driving element 2 will have a speed of moving along the first rotation direction under the action of inertia, at this time, the driving element 2 will also receive the elastic force for driving the driving element 2 to move along the first rotation direction, and the resistance for hindering the driving element 2 to move along the first rotation direction, the resistance generated by the buffering element 3 will reduce the speed of moving along the first rotation direction of the driving element 2, but will not make the driving element 2 change the movement direction rapidly, so the buffering element 3 can slow down the movement speed of the driving element 2, make the door body 100 slowly and stably close the box, and reduce the noise of closing the door.

The utility model discloses door lock device 1000 through setting up swing 4 for driving piece 2 is less at the resistance that the in-process that moves the switching-over position received, and driving piece 2 can move the switching-over position smoothly, and driving piece 2 receives the drive effect of elastic component 5 again afterwards, makes driving piece 2 can continue to rotate smoothly, with the resistance that resists bolster 3, makes the door body 100 can close smoothly.

It can be understood that the operation of closing the door 100 by the operator can be largely divided into two cases, one is to push the door 100 from the open position to the closed position by hand, the other is to swing the door 100, and the door 100 moves by inertia to close the box. The specific process of closing the door body 100 according to some embodiments of the present invention will be described with reference to fig. 12 to 21.

The operator promotes a body 100 and closes the box, when first door hook 1 received the cushioning effect of bolster 3, bolster 3 can apply a resistance to driving piece 2, compare in the first door hook 1 and just promote the condition that driving piece 2 just received the resistance, through setting up swing piece 4, the operator can obtain a feedback of feeling when receiving the cushioning effect of bolster 3, when the operator feels the resistance, can needn't continue to promote a body 100, elastic component 5 can continue to promote driving piece 2 and rotate along first direction of rotation, the user can know the process that the perception body 100 of the perception was closed, high durability and convenient use.

In the second case, the door body 100 is not closed, the door body 100 and the box are in a separated state, the driving part 2 is at an initial position at this moment, the operator swings the door body 100, the first door hook 1 moves towards the box, the first door hook 1 extends into the box, after the first door hook 1 contacts the driving part 2, the driving part 2 and the first door hook 1 only need to overcome the resistance effect of the elastic part 5, the resistance of the two elastic parts 5 is relatively low, the driving part 2 can reach the reversing position relatively easily, the elastic part 5 is stretched to enable the driving part 2 to have a trend rotating along the first rotating direction, at this moment, the elastic part 5 can drive the driving part 2 to continue to rotate along the first rotating direction, the resistance effect that the driving part 2 receives the buffer part 3 is reduced, the door body 100 can be closed smoothly. By providing the swinging member 4, the driving member 2 can reach the reversing position more easily and the door body 100 can be closed more easily than in the case where the first door hook 1 receives resistance just by pushing the driving member 2.

Specifically, as shown in fig. 3, the elastic member 5 includes: the first elastic element 51 and the second elastic element 52, one ends of the first elastic element 51 and the second elastic element 52 on the same side are connected with the same position of the driving element 2, and the other ends of the first elastic element 51 and the second elastic element 52 on the same side are respectively connected with different positions of the box body. When the driving member 2 is at the initial position, the direction of the resultant force of the first elastic member 51 and the second elastic member 52 is parallel to the line between one end of the elastic member 5 and the rotation center of the driving member 2.

By arranging the first elastic member 51 and the second elastic member 52, and at the initial position, the resultant force of the first elastic member 51 and the second elastic member 52 makes the elastic member 5 in the balanced state, and compared with the arrangement of a single elastic member 5, the resultant force of two elastic members 5 makes the elastic member 5 in the balanced state, so that the fault tolerance of the elastic member 5 is higher, the situation that the elastic member 5 deviates from the balanced state due to the situations of mistaken touch or shaking and the like can be avoided, and the working stability of the door lock device 1000 is improved.

In some embodiments of the present invention, the first elastic member 51 and the second elastic member 52 are both configured as a driving spring.

In other embodiments of the present invention, the elastic member 5 includes three or more driving springs, and when the driving member 2 is at the initial position, a connecting line between the connecting position of the driving member 2 and the driving spring and the rotation center of the driving member 2 is parallel to the direction of the resultant force of the driving springs.
