A damper (not shown in the figure) may be further disposed between the first hinge arm 8 or the second hinge arm 9 and the body 1, so that the opening and closing process of the door body 2 is smoother, and the door body 2 is not damaged due to excessive door opening and closing force.
The driving groove 10 can adopt a straight line groove surrounded by two parallel sides and semicircular arcs at two ends as shown in fig. 3, the shape and the size of the sliding block 12 are matched with the width between the two parallel sides of the driving groove 10 and the radius of the semicircular arc, so that the sliding block 12 can slide smoothly in the driving groove 10, and larger shaking can not be generated. The driving groove 10 may also adopt a curved groove or a fold line groove, the curved groove may be an arc line or an S-shaped curve, the fold line groove may be L-shaped, V-shaped, U-shaped, etc., and when adopting this structure, the shape and size of the slider 12 should be suitable for turning in the driving groove 10 to change the movement direction.
As shown in fig. 3, when the door body 2 is in the initial closed position, the second hinge shaft 7 is positioned at a side of the first hinge shaft 6 toward the obstacle 4, and the third hinge shaft 11 is positioned at a side of the first hinge shaft 6 toward the body 1. The central axis of the second hinge arm 9 is at an angle to the central axis of the first hinge arm 8. At this time, the third hinge shaft 11 is located at an end of the driving slot 10 near the second hinge shaft 7 at a distance from the end, i.e., at a position where the third hinge shaft 11 is near the middle of the driving slot 10.
When the door body 2 is in the initial closing position, the door body 2 is close to the barrier 4 on one side of the water chestnut portion 13 formed between the lateral edge of the plane where the door body front panel of the hinge assembly 3 is located and the side edge perpendicular to the lateral edge.
As shown in fig. 3, in the process of opening and closing the door body 2, a sliding pair is formed at the middle part between the driving slot 10 on the second hinge arm 9 and the third hinge shaft 11, and meanwhile, a revolute pair is formed between the bottom of the third hinge shaft 11 and the second hinge arm 9, and when the third hinge shaft 11 rotates around the first hinge shaft 6, the third hinge shaft 11 also rotates around the second hinge shaft 7, and simultaneously, the third hinge shaft 11 slides in the driving slot 10 to provide a driving force for the door body 2, so that the door body 2 (namely, the connection point of the door body 2 and the third hinge shaft 11) generates reciprocating displacement in an included angle range (a direction parallel to the body 1) and a direction B (a direction parallel to the obstacle 4 in the figure) in the direction a shown in fig. 3, and realizes the reciprocating motion of the door body 2 in the direction C, the compound motion of rotating around the first hinge shaft 6 and the second hinge shaft 7.
In the process of opening the door body 2, through the above-mentioned compound motion, the door body 2 produces inward displacement (the direction far away from the barrier 4) in the a direction, and simultaneously the door body 2 produces displacement in the direction far away from the body 1 in the B direction, namely the water chestnut part 13 of the door body 2 also outwards (the direction far away from the body 1) when moving in the direction far away from the barrier 4 (the a direction), so that the door body 2 does not interfere with the barrier 4 on one side in the opening process, and the door sealing strip (not shown in the figure) between the door body 2 and the body 1 can be effectively prevented from being compressed in the process of opening and closing the door body 2, and the service life of the door sealing strip can be effectively prolonged.
As shown in fig. 4, when the door body 2 is in the initial open state, the first hinge arm 8 rotates counterclockwise about the first hinge shaft 6, the second hinge arm 9 rotates counterclockwise about the second hinge shaft 7, and at this time, the third hinge shaft 11 also slides along the drive slot 10 while rotating counterclockwise about the first hinge shaft 6. The third hinge shaft 11 gives a driving force to the door body 2 during the sliding of the third hinge shaft 11 in the driving groove 10. The third hinge shaft 11 slides from an initial near-middle position in the drive slot 10 toward one end far from the second hinge shaft 7, and the door body 2 is displaced in the range of the angle between the a direction and the B direction (direction C in the drawing) while rotating about the first hinge shaft 6, and even if the door body 2 is displaced inward in the a direction (direction far from the obstacle 4) and also displaced in the B direction far from the body 1. At this time, the water chestnut portion 13 of the door body 2 is gradually far away from the obstacle 4, and the outermost end of the water chestnut portion 13 does not exceed the plane where the outer wall of the body 1 is located in the opening process, so that the door body 2 does not interfere with the obstacle 4 on one side in the opening process, and meanwhile, the door body 2 does not compress the door sealing strip between the door body 2 and the body 1. In this process, the door body 2 is displaced inward in the horizontal direction, but the whole door body 2 does not interfere with the other door body 2 opposite to the door body, so that the door opening process is ensured to be smooth.
As shown in fig. 5, the door body 2 is opened to a critical point state, in which the water chestnut portion 13 is located at a position away from the obstacle 4 by a maximum distance, and the third hinge shaft 11 continues to slide in the driving slot 10 from the intermediate position in fig. 4 to the end of the driving slot 10 away from the end of the second hinge shaft 7, at which time the first hinge arm 8 and the second hinge arm 9 are overlapped or parallel. If the drive slot 10 is a curved slot, then the tangent to the drive slot 10 coincides with or is parallel to the first hinge arm 8.
As shown in fig. 6, after the door body 2 continues to open beyond the critical point, the water chestnut portion 13 starts to move from a position away from the obstacle 4 to a direction approaching the obstacle 4, and at this time, the third hinge shaft 11 slides back in the driving slot 10, i.e., slides in a direction approaching one end of the second hinge shaft 7, and the third hinge shaft 11 continues to rotate about the first hinge shaft 6 and the second hinge shaft 7.
As shown in fig. 7, when the door body 2 is continuously opened to 90 °, the third hinge shaft 11 is continuously rotated about the first hinge shaft 6 and the second hinge shaft 7, and the third hinge shaft 11 is slid back to a certain distance in the driving slot 10, and the front panel of the door body 2 is parallel to and close to the obstacle 4. At this time, the water chestnut portion 13 contacts the obstacle 4 or is closest to the obstacle 4, depending on the size of the hinge assembly 3 itself, the size of the door body 2, the installation position of the hinge assembly 3 on the door body 2, and the angle between the first hinge arm 6 and the second hinge arm 7 at the initial position.
As shown in fig. 8, when the door body 2 is continuously opened to more than 90 °, the third hinge shaft 11 is continuously rotated about the first hinge shaft 6 and the second hinge shaft 7, and the third hinge shaft 11 is slid back in the driving slot 10 through the intermediate position and is continuously slid toward one end close to the second hinge shaft 7. In the process, the water chestnut portion 13 starts to move from a position close to the obstacle 4 in a direction away from the obstacle 4.
As shown in fig. 9, when the door body 2 continues to open up to a maximum angle of 135 °, the third hinge shaft 11 continues to rotate about the first hinge shaft 6 and the second hinge shaft 7, and the third hinge shaft 11 slides back in the driving slot 10 to an end portion near one end of the second hinge shaft 7. At this time, the water chestnut portion 13 is at the position farthest from the obstacle 4.
The maximum opening angle of the door body 2 may also be greater than 135 deg., depending on the size of the hinge assembly 3 itself, the size of the door body 2, the mounting position of the hinge assembly 3 on the door body 2, and the angle between the first hinge arm 6 and the second hinge arm 7 in the initial position.
The hinge assembly 3 has a simple structure, three hinge shafts are respectively arranged on the door body 1 and the door body 2, a sliding pair consisting of the driving slot 10 and the third hinge shaft 11 and a revolute pair consisting of the third hinge shaft 11 and the first hinge arm 6 are correspondingly arranged between the door body 1 and the hinge seat 5, and in the opening and closing process of the door body 2, the third hinge shaft 11 slides in the driving slot 10 to drive the door body 2 to generate certain displacement on a horizontal plane while rotating around the first hinge shaft 6 and the second hinge shaft 7, so that the door body 2 does not interfere with one side of the barrier 4 in the opening process, and meanwhile, a door sealing strip between the door body 1 and the door body 2 is not compressed, the opening and closing of the door body 2 are more convenient, and the functions that appliances such as a refrigerator can be freely embedded can be realized, namely, a user can buy a common appliance for use, and can also be independently used.
