[0061] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0062] As mentioned above, in the related technology, in order for the door hook to engage smoothly in the hook groove, the user needs to apply a certain pushing force when closing the door. During the process of the door moving under the pushing force, it will hit the housing at a certain speed, resulting in a lot of noise between the door and the housing when closing the door, and a poor user experience.
[0063] To address at least one of the aforementioned problems, embodiments of this application provide a door lock device and a cooking appliance. The door lock device has a first door hook mounted on a door body and a bracket mounted on a housing. The bracket is connected to a drive member, a connector, and a buffer member. Furthermore, during door closing, the buffer member slows down the movement of the first door hook relative to the bracket, thereby reducing noise during door closing.
[0064] The embodiments of this application will be described in detail below with reference to the accompanying drawings. Figure 1 A schematic diagram of the door lock device in an embodiment of this application is shown; Figure 2 for Figure 1 Internal structure diagram of the central door lock device; Figure 3 for Figure 1 Rear view of the central door lock device;

Figure 2 The straight arrow indicates the first direction, while the curved arrow indicates the first rotation direction; both the first direction and the first rotation direction can be understood as vector directions. Taking the first direction as an example, a vector direction can be understood as a direction with a directional characteristic, such as... Figures 1 to 8 The direction from left to right is the first direction, while the direction from right to left is the opposite direction. The direction in which the connector rotates counterclockwise is the first rotation direction, while the direction in which the connector rotates clockwise is the opposite direction.
[0066] Please refer toFigure 2 The embodiment of the present application provides a door lock device which can be used in a structure with a door body and a box body, and in particular, can be used in a cooking appliance such as a microwave oven, and the door lock device comprises a first door hook 100, a support 200, a connecting piece 300, a driving piece 400 and a buffer piece 500.
[0067] Taking application in a cooking appliance as an example, the first door hook 100 can be mounted on the door body 900 of the cooking appliance, and the connecting piece 300, the support 200, the driving piece 400 and the buffer piece 500 can be mounted on the box body of the cooking appliance. The first door hook 100 comprises a first mounting portion 110 and a first hook-shaped portion 120.
[0068] The first mounting portion 110 can be used to be connected with the door body 900, and the first mounting portion 110 can move relative to the door body 900, and the movement mode can be various, for example, the first mounting portion 110 can be rotatably connected to the door body 900, and for another example, the first mounting portion 110 can move along the up-down direction of the door body 900. Figure 2
[0069] The first hook-shaped portion 120 can be connected to the first mounting portion 110 through welding, screwing, riveting and the like, or alternatively, the two can be formed by integral machining. The first hook-shaped portion 120 can comprise a first portion and a second portion, and the first portion and the second portion can have a certain angle therebetween, so that the two have a first recessed area therebetween, for example, the first hook-shaped portion 120 has a downward recessed first recessed area. Figure 2 The first hook-shaped portion 120 in the door body 900 has a downward recessed first recessed area, and the first recessed area makes the first hook-shaped portion 120 roughly hook-shaped. The first hook-shaped portion 120 can protrude from the door body 900, so that it can extend into one side of the box body after the door body 900 is closed.
[0070] The support 200 can be a plate-shaped structure with a small thickness, and can be used to be connected with the box body. The support 200 can be connected to the box body in various modes, for example, a plurality of through holes are arranged on the support 200, a screw can pass through the through holes and screw the support 200 to the box body through a nut; or alternatively, the support 200 can be clamped to the box body through a buckle fitting mode.
[0071] The connecting piece 300 is rotatably connected to the support 200, that is, the connecting piece 300 can rotate relative to the support 200 about a fixed axis, and the fixed axis is the rotation axis of the connecting piece 300. For example, a rotating through hole can be arranged on the connecting piece 300, and a protruding rotating shaft can be arranged on the support 200, and the connecting piece 300 can be sleeved outside the rotating shaft through the rotating through hole, so as to realize the rotation of the connecting piece 300. In addition, the connecting piece 300 can be used to hook the first hook-shaped portion 120.
[0072] The connecting piece 300 has a sliding surface 330, the first hook-shaped part 120 can slide along the sliding surface 330, and the first hook-shaped part 120 can move between the outside and the inside of the connecting piece 300. Since the first mounting part 110 can move relative to the door body 900, when the first hook-shaped part 120 slides along the sliding surface 330, the first mounting part 110 can also move relative to the door body 900, so that the first hook-shaped part 120 can move between the outside and the inside of the connecting piece 300.
[0073] The inside of the connecting piece 300 can be understood as the front side of the sliding surface 330 along the first direction, and the connecting piece 300 can be used to hook the first hook-shaped part 120 when at least part of the first hook-shaped part 120 is located on the inside of the connecting piece 300. The outside of the connecting piece 300 can be understood as the rear side of the sliding surface 330 along the first direction. It can be understood that when the door body 900 is in an open state, the first hook-shaped part 120 is located on the outside of the connecting piece 300, and when the door body 900 is in a closed state, at least part of the first hook-shaped part 120 is located on the inside of the connecting piece 300.
[0074] The sliding surface 330 can be a curved surface or a flat surface. As an optional implementation of the sliding surface 330, refer to Figure 4 and Figures 5 to 6 The sliding surface 330 and the reference surface 210 gradually increase in distance along the first direction when the first hook-shaped part 120 is located on the outside of the connecting piece 300. When the first hook-shaped part 120 slides along the sliding surface 330 under the action of an external force, it can move from the outer end to the inner end of the sliding surface 330 under the action of the sliding surface 330, and then move to the inside of the connecting piece 300, so as to facilitate the connecting piece 300 to hook the first hook-shaped part 120, and the structure is simple and easy to process.
[0075] Optionally, refer to Figure 2 The first mounting part 110 includes a mounting body 114, a limiting body 112, and a rotating shaft 113 rotatably connected to the door body 900. The door body 900 can be provided with a rotating hole for mounting the rotating shaft 113, and the first mounting part 110 is rotatably connected to the door body 900 by the rotating shaft 113.
[0076] The mounting body 114 is connected to the door body 900 through the elastic body 111, which can be a spring or other structure with elasticity. For example, the elastic body 111 can be a coil spring, one end of which is connected to the mounting body 114 and the other end of which is connected to the door body 900. The mounting body 114 can have various structures. For example, the mounting body 114 can include a mounting hole, and one end of the elastic body 111 can be hooked in the mounting hole. For another example, the mounting body 114 can include a mounting column, and the elastic body 111 can be hooked on the cylindrical surface of the mounting column.
[0077] The door body 900 can be provided with a limiting baffle 910. The limiting body 112 can be used to abut against the limiting baffle 910, and the elastic body 111 is connected to the door body 900, thereby providing an elastic force for abutting the limiting body 112 against the limiting baffle 910 of the door body 900. When the first hook-shaped part 120 slides along the sliding surface 330, the limiting body 112 can overcome the elastic force of the elastic body 111 and rotate with the rotating shaft 113 to separate from the limiting baffle 910.
[0078] It can be understood that, in the process of closing the door, when the first hook-shaped part 120 moves from the outside of the connecting piece 300 to contact the connecting piece 300, the connecting piece 300 can remain stationary, the first hook-shaped part 120 can contact the sliding surface 330 and start to slide along the sliding surface 330. Since the distance between the sliding surface 330 and the reference surface 210 gradually increases in the first direction, it can overcome the elastic force of the elastic body 111 and push the first hook-shaped part 120 to move along the first direction relative to the door body 900. Figure 2 clockwise rotation in the first direction, so that the limiting body 112 can rotate from the state of abutting against the limiting baffle 910 to the state of separating from the limiting baffle 910. When the first hook-shaped part 120 moves away from the sliding surface 330, since there is no pushing force from the sliding surface 330, the first door hook 100 can rotate counterclockwise under the elastic force of the elastic body 111, thereby returning to the position where the limiting body 112 abuts against the limiting baffle 910, and the first hook-shaped part 120 can also move to the inside of the connecting piece 300, thereby facilitating the hooking of the connecting piece 300 to the first hook-shaped part 120.
[0079] The rotation of the first mounting part 110 relative to the door body 900 can realize the movement of the first hook-shaped part 120 along the sliding surface 330, which can quickly realize the hooking of the first hook-shaped part 120 to the connecting piece 300 and simplify the structure of the connecting piece 300.
[0080] Optionally, the mounting body 114 and the limiting body 112 are respectively located on both sides of the rotating shaft 113 in the first direction. For example, the mounting body 114 can be located on one side of the rotating shaft 113 in the first direction, and the limiting body 112 can be located on the other side of the rotating shaft 113 in the first direction. Figure 9In some embodiments, the mounting body 114 can be located on the left side of the rotating shaft 113, and the limiting body 112 can be located on the right side of the rotating shaft 113. In addition, the mounting body 114 and the limiting body 112 can be located on the side of the rotating shaft 113 away from the reference surface 210, i.e., the mounting body 114 and the limiting body 112 can be located below the rotating shaft 113. In this way, the space of the door body 900 can be reasonably utilized, and the thickness of the door body 900 can be reduced.
[0081] The driving member 400 can be connected between the bracket 200 and the connecting member 300. The driving member 400 is configured to drive the connecting member 300 to rotate relative to the bracket 200 after the first hook-shaped part 120 moves to the inner side of the connecting member 300, so that the connecting member 300 hooks the first hook-shaped part 120 and pulls the first hook-shaped part 120 to move in the first direction, thereby closing the door body 900.
[0082] The driving member 400 can be a structure capable of providing power, such as a linear motor, a hydraulic cylinder, a spring, or an elastic rope. For example, when the driving member 400 is a spring, one end of the spring can be connected to the bracket 200, and the other end of the spring can be connected to the connecting member 300. When the first hook-shaped part 120 hooks the connecting member 300, the spring can pull the connecting member 300 to rotate, thereby pulling the first hook-shaped part 120 to move in the first direction, and the door body 900 can move towards the cabinet, thereby achieving door closing. The driving member 400 can provide a pulling force or a pushing force. In some alternative embodiments, the driving member 400 can be a tension spring capable of providing a pulling force, so that the installation position of the driving member 400 is more flexible.
[0083] The buffer member 500 is connected to the bracket 200, and the buffer member 500 is configured to slow down the movement speed of the first hook-shaped part 120 in the first direction. Alternatively, the buffer member 500 can be connected to the connecting member 300, thereby slowing down the rotation speed of the connecting member 300 relative to the bracket 200, and further slowing down the movement speed of the first hook-shaped part 120 in the first direction when the door is closed. Alternatively, the buffer member 500 can not be connected to the connecting member 300. The buffer member 500 can be arranged on the movement path of the first hook-shaped part 120. When the first hook-shaped part 120 moves in the first direction to close the door, the buffer member 500 can abut against the first hook-shaped part 120, thereby generating resistance in the direction opposite to the first direction, and slowing down the movement speed of the first hook-shaped part 120.
[0084] The structure of the buffer member 500 can also be various. For example, the buffer member 500 can include a linear damper or a rotary damper, which can provide resistance to hinder the movement of the first hook-shaped part 120. It can be understood that the power provided by the driving member 400 can be greater than the resistance of the buffer member 500, so that the movement speed of the first hook-shaped part 120 is only slowed down, and the movement direction is not changed.
[0085] Optionally, the buffer 500 comprises a one-way damper for slowing down the moving speed of the first hook 120 along the first direction. The one-way damper does not provide damping when the first hook 120 moves along the direction opposite to the first direction, i.e. the one-way damper only provides damping when the door is closed, and does not provide damping when the door is opened, reducing the resistance of opening the door.
[0086] When the door body 900 is moved towards the cabinet by external force, the first hook 120 moves along the first direction relative to the support 200, and when it moves to the position of the connecting piece 300, the first hook 120 slides along the sliding surface 330 and moves relative to the door body 900 under the action of the sliding surface 330, so that the first hook 120 moves from the outside of the connecting piece 300 to the inside of the connecting piece 300. At this time, the driving piece 400 pulls the connecting piece 300 to rotate relative to the support 200, and in turn pulls the first hook 120 to continue moving along the first direction, and the buffer 500 can provide damping to slow down the moving speed of the first hook 120 along the first direction, thereby reducing the speed of the door body 900 hitting the cabinet, reducing the impact collision between the door body 900 and the cabinet, and in turn reducing the noise when the door is closed.
[0087] Moreover, the door lock device provided by the embodiment has simple structure and low cost, and since the connecting piece 300 is arranged to be rotatable relative to the support 200 but not movable along the first direction relative to the support 200, the longitudinal depth of the support 200 along the first direction can be reduced, so that the door lock device has smaller structural occupied space, can be applied to different volume models, and has strong versatility.
[0088] Figure 1 For Figure 9 The structural schematic view of the support; please refer to Figure 10 In some embodiments, the door lock device comprises a guide piece 600 connected to the support 200. The guide piece 600 can be a strip structure extending along the first direction, and the guide piece 600 is arranged on the side of the first hook 120 away from the reference surface 210, i.e. the first hook 120 can move along the first direction between the guide piece 600 and the connecting piece 300.
[0089] The guide piece 600 has a guide surface 610 parallel to the reference surface 210, which can be located on the surface of the guide piece 600 facing the reference surface 210. When the connecting piece 300 hooks the first hook 120, the bottom surface of the first hook 120 away from the reference surface 210 can slide along the guide surface 610.
[0090] It can be understood that, since the guide surface 610 is located at the bottom of the reference surface 210, when the connecting piece 300 hooks the first hook-shaped part 120, and the connecting piece 300 pulls the first hook-shaped part 120 to move in the first direction, the guide piece 600 can limit the rotation of the first hook-shaped part 120 relative to the door body 900, so that the first hook-shaped part 120 can only reciprocate in the first direction, thereby avoiding disengagement of the first hook-shaped part 120 and the connecting piece 300, and improving the reliability.
[0091] Further, the guide piece 600 further comprises an avoiding surface 620, the avoiding surface 620 and the guide surface 610 are sequentially arranged in the first direction, and the distance between the avoiding surface 620 and the reference surface 210 is greater than the distance between the guide surface 610 and the reference surface 210, and the avoiding surface 620 is used to allow the first hook-shaped part 120 to move relative to the door body 900 along with the first mounting part 110.
[0092] The distance between the avoiding surface 620 and the reference surface 210 is greater, so that a recess can be formed at the top of the end of the guide piece 600 close to the door body 900, and when the first hook-shaped part 120 slides along the sliding surface 330, the recess can allow the first hook-shaped part 120 to rotate relative to the door body 900, so that the first hook-shaped part 120 can be hooked with the connecting piece 300. At the same time, the avoiding surface 620 can also limit the rotation angle of the first hook-shaped part 120 relative to the door body 900, thereby avoiding the phenomenon that the first hook-shaped part 120 cannot be hooked with the connecting piece 300 due to excessive rotation angle caused by excessive force when closing the door.
[0093] Further, the avoiding surface 620 is parallel to the reference surface 210, and the avoiding surface 620 and the guide surface 610 are connected by a transition surface 630, and the distance between the transition surface 630 and the reference surface 210 gradually decreases in the first direction. When the closing force is too large, the first hook-shaped part 120 collides with the sliding surface 330, and the force between them is too large, which causes the first hook-shaped part 120 to rotate too much relative to the door body 900, so that the first hook-shaped part 120 will contact the avoiding surface 620. When the first hook-shaped part 120 continues to move in the first direction, the transition surface 630 can play a transition role, so that the first hook-shaped part 120 can slide along the transition surface 630 to the guide surface 610, and the connecting piece 300 can pull the first hook-shaped part 120 to continue to move in the first direction to close the door body 900, thereby improving the reliability of the device.
[0094] In some embodiments, the connecting piece 300 comprises a first branch arm 310 and a second branch arm 320 connected to the first branch arm 310.
[0095] The first branch arm 310 and the second branch arm 320 can be manufactured by an integrated machining process, the first branch arm 310 and the second branch arm 320 can extend in different directions, one end of the first branch arm 310 is connected with one end of the second branch arm 320, and the connection of the first branch arm 310 and the second branch arm 320 is rotatably arranged on the support 200; for example, the connection of the first branch arm 310 and the second branch arm 320 can be provided with a rotating through hole, the support 200 can be provided with a protruding rotating shaft, and the first branch arm 310 and the second branch arm 320 can be sleeved outside the rotating shaft through the rotating through hole, so as to realize the rotation relative to the support 200. The rotation axis of the connecting piece 300 relative to the support 200 can coincide with the axis of the rotating through hole.
[0096] Among them, the first branch arm 310 can be mainly used for hooking the first hook-shaped part 120, and the second branch arm 320 can be mainly used for connecting the driving piece 400 and the buffer piece 500, so as to simplify the structure of the connecting piece 300 and facilitate processing. Optionally, the output end of the buffer piece 500 can be connected at one end of the second branch arm 320 away from the rotation axis of the connecting piece 300, and the driving piece 400 can also be connected at a position of the second branch arm 320 close to the end.
[0097] The sliding surface 330 can be arranged at one end of the first branch arm 310 away from the rotation axis of the connecting piece 300, the side of the first branch arm 310 away from the second branch arm 320 is the outer side of the connecting piece 300, and the side of the first branch arm 310 towards the second branch arm 320 is the inner side of the connecting piece 300. It can be understood that the inner side and the outer side of the connecting piece 300 can be relative to the first branch arm 310, the side of the first branch arm 310 close to the door body 900 is the outer side, and the second branch arm 320 can be located at the side of the first branch arm 310 away from the door body 900, and the area between the second branch arm 320 and the first branch arm 310 can be the inner side of the connecting piece 300.
[0098] When the first hook-shaped part 120 slides along the sliding surface 330 under the action of an external force and moves from the outer side of the first branch arm 310 to the inner side of the first branch arm 310, the driving piece 400 can pull the second branch arm 320 to rotate, so that the first branch arm 310 can hook the first hook-shaped part 120, thereby pulling the first hook-shaped part 120 to move in the first direction.
[0099] Figure 2 For Figure 1 Structure diagram of the limiting piece Figure 11 ; Figure 2 For Figure 2 Structure diagram of the limiting piece Figure 10 ; please refer to Figure 11 and Figure 2The door locking device further comprises a limiting member 700 connected to the bracket 200, the limiting member 700 is capable of moving relative to the bracket 200 under the driving of the first door hook 100, so that the limiting member 700 abuts against the connecting member 300, thereby limiting the rotation of the connecting member 300 relative to the bracket 200 in the first rotation direction, or the limiting member 700 is separated from the connecting member 300, and the connecting member 300 is capable of rotating relative to the bracket 200 in the first rotation direction, thereby pulling the first hook-shaped part 120 to move in the first direction.
[0100] The moving direction of the limiting member 700 relative to the bracket 200 can be various, for example, the limiting member 700 can rotate relative to the bracket 200, or the limiting member 700 can move relative to the bracket 200 in a direction perpendicular to the bracket 200. The limiting member 700 can abut against the connecting member 300, and optionally, it can abut against the inner side of the first supporting arm 310, or it can abut against the outer side of the second supporting arm 320 away from the first supporting arm 310.
[0101] It can be understood that the limiting member 700 can have a state of abutting against the connecting member 300 and a state of being separated from the connecting member 300. When the first hook-shaped part 120 moves in the first direction or the opposite direction, the first hook-shaped part 120 can simultaneously drive the limiting member 700 to move relative to the bracket, so that the limiting member 700 changes between the two states. Taking closing the door as an example, before the first hook-shaped part 120 moves to the inner side of the connecting member 300, the limiting member 700 can abut against the connecting member 300 to overcome the driving torque of the driving member 400, so that the connecting member 300 remains relatively static and limits the rotation of the connecting member 300 relative to the bracket 200 in the first rotation direction, and after the first hook-shaped part 120 moves to the inner side of the connecting member 300, the limiting member 700 can release the limitation of the connecting member 300, the driving member 400 drives the connecting member 300 to rotate in the first rotation direction, and the inner side surface of the connecting member 300 can be in contact with the first hook-shaped part 120, thereby hooking the first hook-shaped part 120 and pulling it to move in the first direction.
[0102] By arranging the limiting member 700, the timing of the rotation of the connecting member 300 relative to the bracket 200 can be accurately controlled, and the structure of the driving member 400 can be simplified and the cost can be reduced. Of course, in other embodiments, the limiting member 700 can not be arranged, and a sensor can be arranged to detect the position of the first hook-shaped part 120, and the driving member 400 can be driven to output the driving torque according to the position.
[0103] As an optional implementation of the limiting member 700, the limiting member 700 comprises a limiting portion 720, a guiding portion 730, and a limiting member body 710 which is slidably arranged on the support 200 in a direction perpendicular to the support 200; wherein the limiting member body 710 is movable relative to the support 200 in the direction perpendicular to the support 200, and the limiting portion 720 and the guiding portion 730 are both connected to the limiting member body 710. The direction perpendicular to the support 200 can be Figure 12 a direction perpendicular to a paper plane. Alternatively, the limiting portion 720 and the guiding portion 730 can be integrally formed on the limiting member body 710 by an integral molding process. The limiting portion 720 can abut against the second supporting arm 320, thereby playing a role of limiting the rotation of the connecting member 300.
[0104] The guiding portion 730 is used to convert the movement of the first hook-shaped portion 120 in the first direction into the movement of the limiting portion 720 relative to the support 200; and when the first hook-shaped portion 120 is located outside the connecting member 300, the limiting portion 720 abuts against the second supporting arm 320, and when the first hook-shaped portion 120 is located inside the connecting member 300, the limiting portion 720 is separated from the second supporting arm 320, so that the movement of the limiting member 700 relative to the support 200 can be driven by the movement of the first hook-shaped portion 120 in the first direction, without the need to set an additional power source, thereby reducing the cost.
[0105] As an optional implementation of the guiding portion 730, the guiding portion 730 can have a guiding surface 731 which is arranged obliquely relative to the first direction; the guiding surface 731 can be used to contact the first hook-shaped portion 120; and the distance between the guiding surface 731 and the limiting member body 710 gradually increases along the first direction. The guiding surface 731 can be a slope surface which has an oblique angle relative to the support 200, and the guiding surface 731 can convert the movement of the first hook-shaped portion 120 into the movement of the limiting portion 720 in the direction perpendicular to the support 200, and has a simple structure and is easy to process.
[0106] Alternatively, the guiding portion 730 and the limiting portion 720 can be arranged in the first direction. The guiding portion 730 and the limiting portion 720 have a gap 711 for accommodating the second supporting arm 320, the end of the second supporting arm 320 which is away from the rotation axis of the second supporting arm 320 can be located in the gap 711, and the size of the second supporting arm 320 in the first direction can be smaller than the size of the gap 711, so that the second supporting arm 320 can rotate in a small range within the gap 711. Arranging the second supporting arm 320 in the gap can make the structure more compact, and further reduce the size of the support 200.
[0107] In addition, when the door is opened, the first hook-shaped part 120 pulls the connecting piece 300 to rotate relative to the support 200, the second supporting arm 320 can rotate in the gap 711 and abut against the guide part 730, so that the connecting piece 300 can be kept stationary, at this time, the first hook-shaped part 120 can slide along the sliding surface 330 under the action of an external force, so that the first hook-shaped part 120 is more easily separated from the connecting piece 300.
[0108] In some embodiments, the support 200 has a groove 230, the limiting piece body 710 is slidably arranged in the groove 230, and the limiting piece body 710 and the bottom wall of the groove 230 are provided with an elastic piece 740.
[0109] The elastic piece 740 can provide a pushing force, so that after the guide part 730 is separated from the first hook-shaped part 120, the limiting part 720 can be pushed out of the groove 230 by the elastic piece 740 to limit the rotation of the second supporting arm 320.
[0110] Optionally, the bottom wall of the groove 230 can have two sliding holes, the limiting piece body 710 is provided with two oppositely arranged clamping hooks 750 on the side away from the limiting part 720, the clamping hooks 750 can pass through the sliding holes and be located outside the groove 230, and the clamping hooks 750 can abut against the outside of the bottom wall of the groove 230 under the action of the elastic piece 740 to prevent the limiting piece body 710 from being separated from the groove 230.
[0111] Further, the limiting piece body 710 is provided with two oppositely arranged guide columns 760 on the side away from the limiting part 720, and the bottom wall of the groove 230 can have two guide holes, the guide columns 760 can pass through the guide holes and move in the guide holes in a direction perpendicular to the support 200. The guide columns 760 can improve the stability of the movement of the limiting piece 700 and avoid the side of the limiting piece 700 from being raised under the pushing of the first hook-shaped part 120.
[0112] Among them, the two clamping hooks 750 can be spaced apart in a first direction, and the two guide columns 760 can be spaced apart in a direction perpendicular to the first direction, or the two clamping hooks 750 can be spaced apart in a direction perpendicular to the first direction, and the two guide columns 760 can be spaced apart in the first direction.
[0113] Figure 12 A state diagram showing that the door lock device in the embodiment of the application starts to slide along the sliding surface in the door closing process is shown. Please refer to Figure 13 The first hook-shaped part 120 moves to contact the sliding surface 330 in the first direction under the action of an external force, at this time, the limiting part 720 of the limiting piece 700 abuts against the second supporting arm 320 of the connecting piece 300, thereby limiting the rotation of the connecting piece 300 relative to the support 200, and the first hook-shaped part 120 starts to slide along the sliding surface 330.
[0114] Figure 13 Fig. 6 shows a state diagram of the door locking device in the embodiment of the present application in the process of closing the door, when the first hook-shaped part is about to separate from the sliding surface; please refer to Figure 14 The first hook-shaped part 120 slides along the sliding surface 330, and since the sliding surface 330 is arranged obliquely relative to the reference surface 210, the first door hook 100 can rotate in a small range clockwise relative to the door body 900, and the avoiding surface 620 provides sufficient space for the rotation of the first door hook 100. Moreover, during the movement of the first hook-shaped part 120 along the sliding surface 330, the limiting part 720 always abuts against the second branch arm 320 of the connecting piece 300.
[0115] Figure 14 Fig. 7 shows a state diagram of the door locking device in the embodiment of the present application in the process of closing the door, when the first hook-shaped part moves to the inside of the connecting piece; please refer to Figure 15 The first hook-shaped part 120 separates from the sliding surface 330, and the first hook-shaped part 120 can rotate counterclockwise under the action of the elastic body 111 until the limiting body 112 abuts against the limiting baffle 910, and the first hook-shaped part 120 returns to the position before rotating relative to the door body 900. Moreover, the first hook-shaped part 120 starts to slide along the guide surface 731 of the limiting piece 700, and pushes the limiting piece 700 to move inward in the direction perpendicular to the paper surface, thereby gradually reducing the contact area between the limiting part 720 and the second branch arm 320.
[0116] Figure 15 Fig. 8 shows a state diagram of the door locking device in the embodiment of the present application in the process of closing the door, when the first hook-shaped part slides along the guide part; please refer to Figure 16 The first hook-shaped part 120 moves to between the first branch arm 310 and the second branch arm 320, and at this time, the limiting part 720 has not separated from the second branch arm 320, so the first branch arm 310 remains stationary relative to the support 200.
[0117] Figure 16 Fig. 9 shows a state diagram of the door locking device in the embodiment of the present application in the process of closing the door, when the connecting piece hooks the first hook-shaped part; please refer to Figure 17 The first hook-shaped part 120 continues to move along the guide surface 731 until the limiting part 720 separates from the second branch arm 320, and at this time, the connecting piece 300 rotates in the first rotation direction under the driving of the driving piece 400, so that the first branch arm 310 hooks the first hook-shaped part 120 and pulls the first hook-shaped part 120 to move along the guide surface 610. At this time, the buffer 500 provides resistance to the rotation of the connecting piece 300 in the first rotation direction, thereby slowing down the speed of the connecting piece 300 pulling the first hook-shaped part 120 to move in the first direction.
