Example 2
The refrigerator comprises a refrigerator body 6 and a door body 7, wherein refrigerator hinges described in the embodiment 1 are arranged on the left side and the right side of the refrigerator body 6 and the door body 7. The upper hinge assembly 1 on the left side and the upper hinge assembly 1 on the right side are arranged in bilateral symmetry, and the lower hinge assembly 2 on the left side and the lower hinge assembly 2 on the right side are arranged in bilateral symmetry.
The specific working process of the invention is as follows: as shown in fig. 1 and 2, when the door 7 is in the closed state, the lower ends of the upper hinge shafts 4 on the left and right sides fall into the limit grooves 51, the upper ends of the lower hinge shafts 13 on the left and right sides abut against the first limit step 142, and the upper ends of the auxiliary shafts 152 on the left and right sides abut against the second limit step 171.
In the process of opening the door body 7, the lower hinge spindle 13 at the stressed side moves on the slideway of the second arc section C2 and gradually breaks away from the lower hinge step slideway 14. The specific movement process is as follows, because the door body 7 at the side of the stressed force is lifted up initially under the limitation of the height of the slide way of the lower hinge step slide way 14, and when the door body is lifted to 2.5mm, the lower hinge main shaft 13 leaves the first limiting step 142 and enters the slide way of the second arc-shaped section C2. At this stage, the auxiliary shaft 152 follows rotation, and when the door body 7 at the force-bearing side is lifted by 2mm, the auxiliary shaft 152 is separated from the auxiliary slideway 17, and at this time, the lower hinge rotating shaft 15 is automatically reset under the action of the reset spring 18. At the same time, the door body 7 at the stressed side is lifted, the upper hinge spring 10 is compressed, the upper hinge shaft 4 is lifted, and the door body passes through the limit groove 51 and enters the slideway of the first arc-shaped section B2 to move. The motion track of the upper hinge slideway 5 is synchronous with the motion track of the lower hinge ladder slideway 14.
In the process of opening the door body, the door body 7 is fixedly connected with the box body 6, and the upper hinge shaft 4 on the fixedly connected side slides along the slide way of the first horizontal section B1, the lower hinge main shaft 13 slides along the slide way of the second horizontal section C1, and the auxiliary shaft 152 slides along the auxiliary slide way 17 due to the limitation of the slide way on the stressed side. After the upper hinge shaft 4 and the lower hinge main shaft 13 on the stress side are separated from the slide way, as shown in fig. 13 and 14, the lower hinge main shaft 13 and the auxiliary shaft 152 on the fixed side fall into the first limit slot 141 and the second limit slot 172, respectively, and the upper hinge shaft 4 on the fixed side slides to the end of the upper hinge slide way 5. Then, when the door 7 is continuously rotated and opened, the fixed-side lower hinge main shaft 13 and the auxiliary shaft 152 are respectively rotated in the first and second limit grooves 141 and 172, and the fixed-side upper hinge shaft 4 is rotated at the end of the upper hinge slideway 5. Because the door body 7 rotates and opens the in-process, lower hinge main shaft 13 and lower hinge pivot 15 by auxiliary shaft 152 drive synchronous rotation to realize biax support door body 7, make door body 7 rotation process more reliable and realize the purpose of embedding.
In the closing process of the door body 7, the lower hinge step slideway 14 and the upper hinge slideway 5 on the stressed side are simultaneously contacted with the lower hinge spindle 13 and the upper hinge shaft 4 respectively, so that the lower hinge spindle 13 and the upper hinge shaft 4 respectively enter the lower hinge step slideway 14 and the upper hinge slideway 5, at the moment, the lower hinge spindle 13 moves in the slideway of the second arc-shaped section C2, and the upper hinge shaft 4 synchronously moves in the slideway of the first arc-shaped section B2. When the door 7 is closed, the lower hinge spindle 13 enters the slide of the second horizontal section C1, and the upper hinge shaft 4 also simultaneously enters the slide of the first horizontal section B1, and at the same time, the auxiliary slide 17 is landed on the auxiliary shaft 152 of the lower hinge shaft 15.
During the closing process of the door body 7, the lower hinge main shaft 13 and the auxiliary shaft 152 at the fixed side rotate in the first limit slot 141 and the second limit slot 172, respectively, and the upper hinge shaft 4 at the fixed side rotates at the end of the upper hinge slideway 5. When the lower hinge spindle 13 and the upper hinge shaft 4 at the stressed side respectively move on the slideway of the second arc section C2 and the slideway of the first arc section B2, the door body 7 is synchronously driven to lift due to the stepped height difference design of the slideway of the arc section, and when the door body 7 is lifted to a certain height, the lower hinge spindle 13 and the auxiliary shaft 152 at the fixed side respectively enter the slideway of the second horizontal section C1 and the auxiliary slideway 17 to move, and at the moment, the upper hinge shaft 4 also synchronously moves in the slideway of the first horizontal section B1.
When the door body 7 is closed, the lower end parts of the upper hinge shafts 4 positioned at the left and right sides fall into the limit grooves 51, the upper end parts of the lower hinge main shafts 13 positioned at the left and right sides are abutted with the first limit steps 142, and the upper end parts of the auxiliary shafts 152 positioned at the left and right sides are abutted with the second limit steps 171.
