The hinge base 5 is composed of a vertical plate 5a and a horizontal plate 5b, and the vertical plate 5a and the horizontal plate 5b are integrally formed by bending metal plates or fixedly connected by welding. Wherein the vertical plate 5a is fixed to the body 1 by a fastener such as a screw, and the horizontal plate 5b is parallel to the bottom surface of the door body 2.
A first hinge shaft 6 and a second hinge shaft 7 are vertically fixed on the horizontal plate 5b, the first hinge shaft 6 is rotatably connected with a first hinge arm 8, the second hinge shaft 7 is rotatably connected with a second hinge arm 9, the first hinge arm 8 and the second hinge arm 9 are parallel to the bottom surface of the door body 2, the first hinge arm 8 can rotate 360 degrees around the first hinge shaft 6, the second hinge arm 9 can rotate 360 degrees around the second hinge shaft 7, and a driving groove 10 is formed in the second hinge arm 9. The first hinge arm 8 and the second hinge arm 9 may be disposed on the same side of the horizontal plate 5b, and in this embodiment, it is preferable that the first hinge arm 8 is disposed below the horizontal plate 5b, and the second hinge arm 9 is disposed above the horizontal plate 5b, and at this time, the driving groove 10 is a groove penetrating vertically, so that the hinge assembly 3 is more compact in structure and easy to mount.
The hinge assembly 3 further comprises a third hinge shaft 11, the third hinge shaft 11 penetrates through the driving groove 10, the bottom of the third hinge shaft 11 is rotatably connected with the first hinge arm 8, and the top of the third hinge shaft 11 is fixedly connected with the door body 2. The third hinge shaft 11 rotates about the first hinge shaft 6 and slides along the driving slot 10. In order to avoid the third hinge axis 11, a concave portion is provided on the horizontal plate 5b of the hinge base 5.
In order to make the sliding of the third hinge shaft 11 in the driving slot 10 smoother, the third hinge shaft 11 is connected with the driving slot 10 by a sliding block 12. The structure of the sliding block 12 is matched with that of the driving groove 10, so that the sliding block 12 can slide stably in the driving groove 10, and the third hinge shaft 11 is fixedly connected with the sliding block 12.
As shown in fig. 2 and 3, the third hinge shaft 11 is divided into an upper section, a middle section and a lower section, the cross section of the upper section 11a is preferably square, a square shaft hole is correspondingly arranged on the bottom surface of the door body 2, and the top of the upper section 11a of the third hinge shaft 11 is inserted into the shaft hole for fixed connection, so that the installation is convenient, and the third hinge shaft 11 and the door body 2 do not rotate relatively; the cross section of the middle section 11c is preferably square, a square shaft hole is correspondingly arranged on the sliding block 12, and the middle section 11c of the third hinge shaft 11 is inserted into the shaft hole for fixed connection, so that the installation is convenient, and the third hinge shaft 11 and the sliding block 12 can not rotate relatively; the lower section 11b has a circular cross-section allowing the third hinge shaft 11 to rotate around the first hinge arm 8.
A damper (not shown in the figure) can be further arranged 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 more stable, and the door body 2 cannot be damaged due to overlarge door opening and closing force.
The driving groove 10 can be a straight line groove enclosed by two parallel edges and two semicircular arcs at two ends as shown in fig. 3, and the shape and size of the sliding block 12 are matched with the width between the two parallel edges and the radius of the semicircular arc of the driving groove 10, so that the sliding block 12 can slide smoothly in the driving groove 10, and no large shaking is generated. The driving slot 10 may also be a curved slot, which may be an arc or an S-shaped curve, or a broken slot, which may be L-shaped, V-shaped, U-shaped, etc., and when this structure is adopted, the shape and size of the slider 12 are suitable for turning and changing the moving direction in the driving slot 10.
As shown in fig. 3, when the door 2 is in the initial closing position, the second hinge axis 7 is located on a side of the first hinge axis 6 facing the obstacle 4, and the third hinge axis 11 is located on a side of the first hinge axis 6 facing the body 1. The centre axis of the second hinge arm 9 is at an angle to the centre 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 close to the second hinge shaft 7 and at a distance from the end, i.e., at a position where the third hinge shaft 11 is close to the middle of the driving slot 10.
When the door body 2 is positioned at the initial closing position, the water caltrop part 13 formed between the transverse edge of the plane of the door body front panel of the hinge assembly 3 and the side edge vertical to the transverse edge of the door body 2 contacts with the obstacle 4 at one side.
As shown in fig. 3, in the process of opening and closing the door body 2, a sliding pair is formed in the middle between the driving groove 10 on the second hinge arm 9 and the third hinge shaft 11, and a rotating pair is formed between the bottom of the third hinge shaft 11 and the second hinge arm 9, 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 the third hinge shaft 11 slides in the driving groove 10, so that a driving force is given to the door body 2, and the door body 2 (i.e. the connection point of the door body 2 and the third hinge shaft 11) generates a reciprocating displacement in the included angle range (C direction in the figure) between the a direction (the direction parallel to the body 1) and the B direction (the direction parallel to the obstacle 4) shown in fig. 3, and a compound motion of the door body 2 in the C direction, the rotation around the first hinge shaft 6 and the rotation around the second hinge shaft 7 is realized.
In the process of opening the door body 2, through the compound motion, the door body 2 generates inward displacement (in the direction away from the barrier 4) in the direction a, and meanwhile, the door body 2 generates displacement in the direction B in the direction away from the body 1, namely, the water caltrop part 13 of the door body 2 moves outwards (in the direction B away from the body 1) while moving in the direction (in the direction a) away from the barrier 4, 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 2 is in the initial opening state, the first hinge arm 8 rotates counterclockwise around the first hinge shaft 6, the second hinge arm 9 rotates counterclockwise around the second hinge shaft 7, and the third hinge shaft 11 slides along the driving slot 10 while rotating counterclockwise around the first hinge shaft 6. During the process that the third hinge shaft 11 slides in the driving groove 10, the third hinge shaft 11 gives a driving force to the door body 2. The third hinge shaft 11 slides from an initial position close to the middle to an end far from the second hinge shaft 7 in the driving slot 10, so that the door body 2 rotates around the first hinge shaft 6 and simultaneously displaces in an included angle range between the direction a and the direction B (the direction C in the figure), and even if the door body 2 displaces in the direction a inwards (the direction far from the obstacle 4), the door body 2 also displaces in the direction B far from the body 1. At this moment, the water caltrop part 13 of the door body 2 is gradually far away from the barrier 4, and the outermost end of the water caltrop part 13 cannot exceed the plane of the outer wall of the body 1 in the opening process, so that the door body 2 cannot interfere with the barrier 4 on one side in the opening process, and meanwhile, the door body 2 cannot compress a door sealing strip between the door body 2 and the body 1. In the process, although the door body 2 generates inward displacement in the horizontal direction, the whole door body 2 cannot interfere with the other door body 2 opposite to the door body 2, and the smooth door opening process is ensured.
As shown in fig. 5, the door 2 is opened to a critical point state, where the diamond-shaped portion 13 is at a maximum distance away from the obstacle 4, and the third hinge shaft 11 slides continuously in the driving slot 10 from the middle position in fig. 4 to an end of the driving slot 10 away from the second hinge shaft 7, at which time the first hinge arm 8 and the second hinge arm 9 are overlapped or parallel. If a curved slot is used for the drive slot 10, the tangent of the drive slot 10 now coincides with or is parallel to the first hinge arm 8.
As shown in fig. 6, after the door 2 is opened beyond the threshold point, the diamond-shaped portion 13 starts to move from a position far away from the obstacle 4 to a position close to the obstacle 4, and at this time, the third hinge shaft 11 slides back in the driving slot 10, i.e., slides to a position close to one end of the second hinge shaft 7, and the third hinge shaft 11 continues to rotate around the first hinge shaft 6 and the second hinge shaft 7.
As shown in fig. 7, when the door 2 is opened to 90 °, the third hinge shaft 11 continues to rotate around the first hinge shaft 6 and the second hinge shaft 7, the third hinge shaft 11 slides back to a certain distance in the driving slot 10, and the front panel of the door 2 is parallel to and close to the obstacle 4. At this time, the diamond portion 13 contacts 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 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 at the initial position.
As shown in fig. 8, when the door 2 is opened further to more than 90 °, the third hinge shaft 11 continues to rotate around the first hinge shaft 6 and the second hinge shaft 7, and the third hinge shaft 11 slides back in the driving slot 10 and continues to slide toward the end near the second hinge shaft 7 through the middle position. In the process, the diamond-shaped part 13 starts to move from a position close to the obstacle 4 to a direction away from the obstacle 4.
As shown in fig. 9, when the door 2 is opened to a maximum angle of 135 °, the third hinge shaft 11 rotates around 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 near one end of the second hinge shaft 7. At this time, the diamond-shaped portions 13 are at the farthest positions from the obstacle 4.
The maximum opening angle of the door body 2 may also be greater than 135 °, 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 body 1 and the door body 2, a sliding pair consisting of the driving groove 10 and the third hinge shaft 11 and a rotating 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 groove 10 to drive the door body 2 to generate certain displacement on the horizontal plane by driving force for the door body 2 while rotating around the first hinge shaft 6 and the second hinge shaft 7, so that the door body 2 does not interfere with the obstacle 4 on one side in the opening process, and meanwhile, the door sealing strip between the body 1 and the door body 2 is not compressed, thereby the opening and closing of the door body 2 are more convenient, the function of freely embedding appliances such as a refrigerator and the like can be realized, namely, a user can embed one ordinary appliance, or may be used independently.
Example two:
the difference from the first embodiment is that in the present embodiment, the first hinge arm 8 is preferably disposed above the horizontal plate 5b, and the second hinge arm 9 is preferably disposed below the horizontal plate 5 b.
