The profile curve comprises a starting end, a final end, a first segment 251 located between the starting end and the final end, the guide 32 being located at the starting end when the door body 2 is in the closed state; during the process of opening the door 2 from the closed state, the guide member 32 moves toward the terminal along the first section 251, so as to drive the hinge shaft 31 to move from the first end 2411 to the third end 2421 relative to the second slot 242.
As shown in fig. 4 and 6, when the door 2 is opened to a first predetermined angle, the guide 32 moves along the first section 251 toward an end of the first section 251 near the terminal end, so that the hinge shaft 31 moves from the first end 2411 toward the third end 2421 until the door 2 is opened to a second predetermined angle, and at this time, the hinge shaft 31 moves to the third end 2421. The second preset angle is larger than the first preset angle.
Specifically, the first section 251 is arc-shaped, and the first section 251 is gradually separated from the second slot 242 along the direction from the start end to the end, so that the hinge shaft 31 can be driven to move toward the third end 2421 when the guide member 32 moves along the first section 251 toward the end.
In an embodiment, the shaft groove 24 is disposed on the movable seat, the second shaft groove 242 extends along the thickness direction of the door body 2, and the first end 2411 is located at a side of the second shaft groove 242 opposite to the first end 2411, which is far away from the fixed seat 3, i.e., the first end 2411 is located at a front side of the third end 2421. When the opening angle of the door body 2 is between 0 ° and 90 °, the included angle between the extending direction of the second shaft slot 242 and the first direction is gradually reduced, so that when the opening angle of the door body 2 is between 0 ° and 90 °, the door body 2 translates to move the hinge shaft 31 from the first end 2411 to the third end 2421, and the door body 2 moves away from the case 1 while moving toward the first direction. On the one hand, the door body 2 is far away from the box body 1 along the first direction, so that the door body 2 is far away from the box body 1 along the first direction as far as possible, the opening of the door body 2 is ensured, and a user can conveniently take and put articles; on the other hand, the door body 2 moves away from the box body 1, so that the distance between the door body 2 and the box body 1 is increased, interference between the rear wall of the door body 2 and the box body 1 in the opening process of the door body 2 can be prevented, and meanwhile, for the embedded refrigerating device 100, the front wall 21 of the door body 2 is located at one end of the pivoting end 23 and protrudes forward from the front end of the cabinet 6, so that interference between the door body 2 and the cabinet 6 in the rotating process of the door body 2 can be reduced. Of course, it is not limited thereto, and it is understood that the extending direction of the second shaft slot 242 may be adjusted according to specific requirements to control the translation direction of the door body 2.
Specifically, in one embodiment, the second preset angle is 90 °. Of course, this is not a limitation.
Further, in the present invention, in the process of opening the door body 2 from the closed state to the maximum preset angle, the movement track of the door body 2 is set as follows: when the door body 2 is opened to a first preset angle from a closed state, the door body 2 rotates in situ; when the door body 2 is opened to a first predetermined angle and continues to rotate and open, the guide 32 moves along the first section 251 toward an end of the first section 251 near the terminal end, so that the hinge shaft 31 moves along the second shaft slot 242 from the first end 2411 toward the third section 253, and the door body 2 moves in a first direction and simultaneously moves in a direction away from the case body 1; in the process that the door body 2 is opened to the second preset angle and is continuously opened to the maximum preset angle, the hinge shaft 31 is moved from the third end 2421 to the first end 2411 in a reset manner, so that the door body 2 moves to the second direction, thereby further increasing the opening of the door body 2, and facilitating the user to take and put the articles. Of course, this is not a limitation.
It is known that when the door body 2 is in a closed state, the door seal on the door body 2 is tightly adsorbed on the box body 1, so that when the door body 2 is opened in a self-closing state, the door body 2 is firstly rotated in situ by a first preset angle, and the door seal can be firstly separated from the box body 1, so that deformation and damage of the door seal are prevented, and the subsequent sealing performance of the door body 2 is affected. Correspondingly, in the final stage of closing the door, the door body 2 rotates in situ to be closed, so that the deformation of the door seal can be reduced, and the smooth closing of the door body 2 is facilitated.
Meanwhile, for the refrigerating device 100 with the turnover beam, the door body 2 rotates in place when being opened from the closed state, so that the turnover beam can turn over and separate from the guide structure on the box body 1, and the subsequent door body 2 can be opened continuously in a rotating way. Correspondingly, in the process from the closing to the final stage, the door body 2 rotates to the closing in situ, and the overturning beam can overturn to cover the gap between the left door body 2 and the right door body 2 under the guidance of the guide structure on the box body 1.
In one embodiment, the first preset angle is between 30 ° and 60 °. Of course, this is not a limitation.
Further, the driving assembly further includes an elastic driving assembly 5 connected to the hinge shaft 31, and the elastic driving assembly 5 is configured to restrict the hinge shaft 31 from moving along the second shaft slot 242 when the door body 2 is opened from the closed state to the first preset angle, i.e., to maintain the hinge shaft 31 at the first end 2411, thereby allowing the door body 2 to be rotated in place. Meanwhile, when the door body 2 continues to rotate from the second preset angle, the elastic driving assembly 5 drives the hinge shaft 31 to move from the third end 2421 to the first end 2411, so that the door body 2 translates in the second direction while rotating. In addition, after the door body 2 is opened to a maximum preset angle, the elastic driving assembly 5 is configured to limit the movement of the hinge shaft 31 along the second shaft slot 242, so that the hinge shaft 31 can move along the first shaft slot 241 toward the second end 2412 under the action of the electromagnetic driving assembly 4.
In one embodiment, the elastic driving assembly 5 includes a mounting seat 51 fixedly disposed opposite to the shaft slot 24, a slider 52 connected to the hinge shaft 31, and a spring 53 connecting the mounting seat 51 and the slider 52. The spring 53 maintains the hinge shaft 31 at the first end 2411 during the rotation of the door 2 from the closed state to the first preset angle. The hinge shaft 31 moves toward the third end 2421 during the door body 2 is rotated to be opened from the first preset angle to the second preset angle, and the spring 53 is in a compressed state. In the process that the door body 2 continues to open from the second preset angle to the maximum preset angle, the hinge shaft 31 is driven to move from the third end 2421 to the first end 2411 under the action of the elastic restoring force of the spring 53. Of course, this is not a limitation.
Specifically, when the shaft groove 24 is disposed on the door body 2, the mounting seat 51 of the elastic driving assembly 5 is fixed on the door body 2, so that the mounting seat 51 and the shaft groove 24 are disposed relatively fixedly. And the elastic driving component 5 can act on the hinge shaft 31, so that the limit action of the elastic driving component 5 on the hinge shaft 31 is not influenced by the switch door body 2.
Further, as shown in fig. 9 and 11, the slider 52 has a chute 521 at a position corresponding to the first shaft slot 241, the hinge shaft 31 is located in the chute 521, and the chute 521 has a position and a size corresponding to the first shaft slot 241. After the movable seat is opened to a maximum preset angle, the hinge shaft 31 moves relative to the first shaft slot 241 and moves relative to the slide groove 521. Therefore, in the process of translating the door body 2 after opening to the maximum preset angle, the sliding groove 521 gives way to the hinge shaft 31, so as to avoid interference between the sliding block 52 and the hinge shaft 31, and influence the translation of the door body 2.
Further, as shown in fig. 1 and 4, the profile curve further has a second section 252 that communicates the start end and the first section 251, and the second section 252 is an arc with the first end 2411 as a center. During the process of opening the door body 2 from the closed state to the first preset angle, the guide member 32 moves along the second section 252 with the hinge shaft 31 as a center, and at this time, the hinge shaft 31 is maintained at the first end 2411 under the cooperation of the elastic driving assembly 5, so that the door body 2 can be rotated in place by the preset angle.
It will be appreciated that the length of the second section 252 may be determined based on the angle at which the door 2 is required to be rotated in place. Meanwhile, by providing the second section 252 that cooperates with the guide member 32, the hinge shaft 31 can be further limited, so that the hinge shaft 31 is maintained at the first end 2411 during the process of opening the door body 2 to the first preset angle.
Further, as shown in fig. 6 and 8, the profile curve further has a third section 253 that connects the first section 251 and the terminal end, and the third section 253 gradually approaches the second axial slot 242 along the direction from the starting end to the terminal end. When the door body 2 is opened to the second preset angle and continues to be opened, the guide member 32 abuts against the third section 253 and moves towards the terminal, and under the cooperation of the elastic driving assembly 5, the hinge shaft 31 is driven to move from the third end 2421 to the first end 2411, and the door body 2 moves towards a second direction opposite to the first direction.
It can be appreciated that by providing the third section 253, when the elastic driving assembly 5 drives the hinge shaft 31 to move toward the first end 2411 relative to the second shaft slot 242, the hinge shaft 31 can be slowly moved toward the first end 2411, so that the translational stability of the door body 2 is enhanced, noise is reduced, and damage caused by collision of the hinge shaft 31 with the wall of the second shaft slot 242 is prevented.
Further, a relief groove 26 is concavely formed in the door body 2 at a position corresponding to the profile curve of the cam structure 25, and the shape of the relief groove 26 is the same as the profile curve. The guide 32 extends into the relief groove 26. On the one hand, when the door body 2 is installed, the height of the door body 2 needs to be adjusted, if the height of the door body 2 is adjusted too much, the guide piece 32 is easy to separate from the cam structure 25, so that the guide piece 32 can be ensured to be always matched with the cam structure 25, and the reliability of the matched structure of the guide piece 32 and the cam structure 25 when the door body 2 is adjusted up and down can be ensured; on the other hand, the cooperation of the guide piece 32 with the yielding groove 26 can also enable the guide piece 32 to be always kept on the contour curve of the cam structure 25, so that the translation stability of the door body 2 is enhanced.
It will be appreciated that in the embodiment having the relief groove 26 and the guide member 32, the relief groove 26 has a relief section 261, and when the door body 2 translates after rotating to the maximum preset angle, the guide member 32 moves in the relief section 261 to enable the door body 2 to translate.
In summary, in the hinge mechanism of the present invention, after the movable seat is opened to the maximum preset angle relative to the fixed seat 3, the driving component drives the movable seat to translate, that is, after the door body 2 rotates to the maximum angle, the driving component drives the door body 2 to independently do translational motion, so that the translational direction and distance of the door body 2 can be controlled according to the requirement of the user, and the control is simple.
