the long outer arc edge 42 in the cam 4 is C (left side between AB) and D (right side between AB) respectively;
the center point of the track frame 5 is E 0 ，E 0 The track of (2) is E;
taking the example that the track frame 5 rotates anticlockwise outside the cam 4, the track change process is as follows:
1. when the AB line section is perpendicular to the L3 in the figure 7, A is at the top sharp angle of the track frame 5, and two ends of the A are tangent to the L1 and the L2 respectively; b is tangent to L3 at the center of the bottom straight line of the track frame 5; C. the top end of the cam 4 is coincident with the tangential point of the two ends of the cam A, and the bottom end of the cam C, D is coincident with the tangential point of the cam B, so that the cam 4 is still three tangential points on the L1, the L2 and the L3;
2. referring to fig. 8, the track frame 5 rotates counterclockwise, when the AB line segment is perpendicular to the L2, the B is at the bottom sharp corner of the track frame 5, and the two ends are tangent to the L1 and the L3 respectively; a is tangent to L2 at the center of the straight line at the top of the track frame 5; C. the tangential points of the bottom end D and the two ends B are coincident, and the top end C, D is coincident with the tangential point A, so that the cam 4 is still three tangential points on L1, L2 and L3;
3. referring to fig. 9, the track frame 5 rotates counterclockwise, when the AB line segment is perpendicular to L1, a is at the top sharp corner of the track frame 5, and both ends are tangent to L2 and L3 respectively; b is tangent to L1 at the center of the bottom straight line of the track frame 5; C. the top end of the cam 4 is coincident with the tangential point of the two ends of the cam A, and the bottom end of the cam C, D is coincident with the tangential point of the cam B, so that the cam 4 is still three tangential points on the L1, the L2 and the L3;

5. referring to fig. 11, the track frame 5 rotates counterclockwise, when the AB line segment is perpendicular to L2, a is at the top sharp corner of the track frame 5, and both ends are tangent to L3 and L1 respectively; b is tangent to L2 at the center of the bottom straight line of the track frame 5; C. the top end of the cam 4 is coincident with the tangential point of the two ends of the cam A, and the bottom end of the cam C, D is coincident with the tangential point of the cam B, so that the cam 4 is still three tangential points on the L1, the L2 and the L3;
6. referring to fig. 12, the track frame 5 rotates counterclockwise, when the AB line segment is perpendicular to L1, B is at the bottom sharp corner of the track frame 5, and both ends are tangent to L3 and L2 respectively; a is tangent to L1 at the center of the straight line at the top of the track frame 5; C. the tangential points of the bottom end D and the two ends B are coincident, and the top end C, D is coincident with the tangential point A, so that the cam 4 is still three tangential points on L1, L2 and L3;
7. and (5) repeating the step 1 and repeating the steps.
As can be seen from the above track changing process, when the track frame 5 rotates outside the cam 4, three points are always tangential to the cam 4, so that the track frame can be pushed out, the track frame 5 on the refrigerator door 1 rotates on the cam 4 (the hinge body 3 is fixed on the refrigerator door 2, so that the cam 4 remains fixed during rotation), and the track frame 5 retracts inwards (in the arrow direction) during rotation of the track frame 4, as shown in fig. 13, so that the point F where interference is most likely to occur avoids interference.
In contrast to a conventional hinge that rotates about an axis, each point on the hinge of the present solution changes with rotation. Compared with the prior art, the method has the advantages that the limit mode is realized by matching the Lo triangle block with the track frame in a rotating manner, because the Lo triangle block is in contact with the track frame at four points, and the track change is small, the inward retraction amplitude is obviously lower than that of the technical scheme, and therefore, compared with the Lo triangle block, the method can realize the more compact placement of a refrigerator and a deep narrow space or other objects placed in the deep narrow space, thereby not only enabling the occupied space of the refrigerator to be smaller, but also enabling a gap to be smaller and more attractive, being not easy to fall dust, and having the advantages of simple structure and low manufacturing cost from the aspect of production and manufacture.
In addition, if the radius of A, B is set to R, and the radius of C, D is set to R, it can be inferred that if the ratio of R/R is increased, the track change of the refrigerator door 1 is increased, and the inward retraction amplitude is correspondingly increased; conversely, if the R/R ratio is reduced, the track variation of the refrigerator door 1 is reduced and the magnitude of the inward retraction is correspondingly reduced. Can be adaptively adjusted according to the requirements of the refrigerator size and the embedded place.
Example 3
