[0024] See also Figure 1-4 , is a schematic diagram of a refrigerator 100 provided in one embodiment of the present invention.
[0025] In a preferred embodiment, the refrigerator 100 includes a box body 10 and a shelf assembly 20 disposed in the box body 10, wherein the shelf assembly 20 includes a shelf 30 and a connecting rod mechanism 40 connected to the bottom of the shelf 30; one side of the connecting rod mechanism 40 is fixed to the box body 10, and the other side moves relative to the box body 10, and the connecting rod mechanism 40 drives the shelf 30 to move together, so that the shelf 30 has a first state of being located in the box body 10 and a second state of being moved out of the box body 20. The connecting rod mechanism 40 drives the shelf 30 to move, so that the shelf 10 can be rotated from the box body 10 to the outside of the box body 10, so that the food inside the shelf 30 can be taken out conveniently.
[0026] Preferably, a baffle 31 is provided at the edge of the shelf 30 to form a box-shaped space.
[0027] Specifically, there is a baffle of a certain height around the shelf 30 to prevent food from falling. The bottom of the shelf 30 is a connecting rod mechanism 40, which can be rotated out with the shelf 30. In this way, the user can see all the food in the shelf 30 and easily take out the food he wants, and it will not be troublesome to put it back after use. It improves the user's experience of using the refrigerator, increases comfort, and saves time.
[0028] Preferably, the shelf 30 is formed as follows: a rectangular body is short of material along the diagonal direction to form a first yielding edge 32 and a second yielding edge 33; when the shelf 30 is in the second state, the first yielding edge 32 abuts against the inner wall of the box body 10; the first yielding edge 32 and the second yielding edge 33 prevent interference with the inner wall of the box body during rotation; the first yielding edge 32 abuts against the inner wall of the box body 10 to prevent the shelf 30 from excessively rotating.
[0029] Preferably, the ratio of the area of the shelf 30 to the area of the rectangular plate is less than or equal to 94%, so as to ensure that the maximum bottom area of the shelf 30 is retained without interfering with the box body 10 .
[0030] Specifically, refer to Figure 5-7 As shown, during the rotation of the rack 30, if it is a rectangular body, it will interfere with the box 10. Through interference simulation calculation, the first and second side edges 32 and 33 are set to retain the shape of the maximum bottom area of the rack 30 without interference, so as to accommodate the maximum amount of food. More specifically, during the process of the rectangular body lacking food along the diagonal direction to form the first and second side edges 32 and 33, the ratio of the lacking food area to the rectangular body does not exceed 6%.
[0031] The shelf 30 is formed by a rectangular body with a missing portion. The missing portion position and shape of the rectangular body are based on ensuring that there is no interference with the box body 10. In this embodiment, the missing portion is formed as a triangle along the diagonal direction. The first yielding edge 32 and the second yielding edge 33 are straight lines. The specific positions of the missing portion are the left front missing portion and the right rear missing portion when the user faces the refrigerator 100. In a more preferred embodiment, it is not limited to a triangle, but can also be a fan-shaped portion. In this case, the first yielding edge 32 and the second yielding edge 33 are arc-shaped.
[0032] Preferably, one side of the connecting rod mechanism 40 is a first rod 41, and the connecting rod mechanism includes a second rod 42 and a third rod 43 which are movably connected to both ends of the first rod 41 so as to rotate relative to the first rod 41; the second rod 42 is fixedly connected to the bottom of the shelf 30, and the third rod 43 is slidably connected to the bottom of the shelf 30.
[0033] Specifically, the first rod 41 is fixed to the box body 10, and the first rod 41 includes a first end 411 and a second end 412 at both ends. In order to achieve better load-bearing, the first rod 41 is actually set to be wider and thicker. The second rod 42 is movably connected to the first end 411, and the third rod 43 is movably connected to the second end 412. The second rod 42 is fixedly connected to the rack 30 to drive the rack 30 to rotate. Similarly, in order to achieve better load-bearing, the second rod 42 is actually set to be wider and thicker. The third rod 43 is slidably connected relative to the rack 30, so that the connecting rod mechanism 40 can move relative to the rack 30.
[0034] It can be understood that during the rotation of the shelf assembly 20 relative to the box body 10, the shelf 30 rotates relative to the box body 10 around the first end 411, and the connecting rod mechanism 40 needs to rotate relative to the box body 10 around the first end 411 and the second end 412 at the same time, that is, the rotation trajectories of the shelf 30 and the connecting rod mechanism 40 do not overlap. Therefore, there is relative movement between the shelf 30 and the connecting rod mechanism 40 to achieve the overall harmonious movement of the shelf assembly 20.
[0035] Preferably, the connecting rod mechanism 40 includes a plurality of fourth rods 44 , which are parallel to the first rod 41 and evenly spaced in the lateral direction, and both ends of each fourth rod 44 are movably connected to the second rod 42 and the third rod 43 , so as to enhance the stability of the supporting structure of the connecting rod mechanism 40 .
[0036] Specifically, each of the fourth rods 44 has the same length, so that the second rod 42 and the third rod 43 can maintain an equal distance and remain parallel. In the first state of the rack 30, the second rod 42 and the third rod 43 are perpendicular to the fourth rod 44, that is, they are also perpendicular to the first rod 41, so that the connecting rod mechanism 40 forms a plane ladder shape. At this time, the connecting rod mechanism 40 is located in the middle of the rack 30 to better bear the weight.
[0037] When the shelf 30 is in the second state, the shelf 30 is rotated outward so as to be partially exposed outside the box body 10, the shelf 30 rotates around the first end 411 of the first rod 41, the third rod 43 rotates around the second end 412 of the first rod 41, and the second rod 42 rotates around the first end 411 of the first rod 41, thereby rotating the connecting rod mechanism 40. More specifically, the first rod 41 is fixed to the box body 10 and does not move, the second rod 42 is fixed relative to the shelf 30, the connecting rod mechanisms 40 are movably connected to each other, and the second rod 42, the third rod 43 and the fourth rod 44 all rotate relative to the first rod 41. Finally, the second rod 42 and the third rod 43 remain parallel, and the fourth rod 44 is also parallel to the first rod 41, but the second rod 42 and the third rod 43 are no longer perpendicular to the first rod 41, but are rotated relative to each other by a certain angle. Figure 7 visible.
[0038] In other embodiments, the connecting rod mechanism 40 may also be provided with a plurality of cross-arranged fourth rods 44 , and two ends of each of the fourth rods 44 are movably connected to the second rod 42 and the third rod 43 .
[0039] Preferably, the second rod 42 is provided with a first fixed point 421 and a second fixed point 422 fixedly connected to the rack 30, and the third rod 43 is provided with a sliding point 431 slidably connected to the rack 30; the sliding point 431, the first fixed point 421 and the second fixed point 422 form a triangle, and the stability principle of the triangle is utilized to maintain the stability of the rack 30 so that it does not tip over or fall.
[0040] Specifically, the shelf 30 is slidably supported by the connecting rod mechanism 40, and the sliding support is realized by a first fixed point 421, a second fixed point 422 and a sliding point 431. The first fixed point 421 and the second fixed point 422 are fixedly connected to the shelf 30, and the sliding point 431 is movable and will slide along a certain trajectory, thereby ensuring that there are always three points for support during the process of rotating the shelf 30, thereby maintaining the stability of the shelf 30.
[0041] Preferably, when the shelf 30 is in the first state, the distance between the sliding point 431 and the first fixed point 421 is equal to the distance between the second fixed point 422 , forming an isosceles triangle. The triangle is maintained at any moment when the shelf 30 moves to the second state, thereby maintaining the stability of the shelf 30 .
[0042] Preferably, an arc track 34 for the sliding point 431 to slide is provided at the bottom of the shelf 30, and the arc track 34 corresponds to the movement trajectory of the sliding point 431 to ensure that the connecting rod mechanism 40 drives the shelf 30 to rotate out of the box 10 along a predetermined track.
[0043] The origin of the motion trajectory of the sliding point 431, that is, the origin of the shape of the arc track 34: the connecting rod mechanism 40 drives the shelf 30 to rotate, and the shelf 30 and the connecting rod mechanism 40 move synchronously and there is relative motion between them. Specifically, the sliding point 431 rotates around the first end 411 of the first rod 41, but at the same time, the shelf 30 where the sliding point 431 is located is also moving. The motion trajectory of the sliding point 431 is the track left by the sliding point 431 on the shelf 30, so the rotational motion of the sliding point 431 and the relative motion with the shelf 30 must be comprehensively calculated to obtain the motion trajectory of the sliding point 431.
[0044] The beneficial effects of the present invention are as follows: the rack 30 is driven to move by the connecting rod mechanism 40, so that the food inside the rack 30 is conveniently taken out; the rack 30 and the connecting rod mechanism 40 are fixedly connected by the second rod 42, and are slidably connected by the third rod 43, so that the relative movement between the two is realized; the second rod 42 is provided with a first fixed point 421 and a second fixed point 422, and the third rod 43 is provided with a sliding point 431, and the three are in a triangle, which is conducive to the connecting rod mechanism 40 to stably support the rack 30; the rack 30 is short of material to form a first yielding edge 32 and a second yielding edge 33 to ensure that there is no interference with the box body 10 during the rotation process; and the short of material area does not exceed 6% to retain the maximum bottom area of the rack 30.
