[0047] In one embodiment of the present application, the opening angle of the door body 500 is equal to the first opening angle, and the distance between the first groove wall 114 and the second groove wall 125 is 20-25 mm. Preferably, the opening angle of the door body 500 is equal to the first opening angle, and the distance between the first groove wall 114 and the second groove wall 125 is 22.8 mm.

[0048] In one embodiment of the present application, the opening angle of the door body 500 is equal to the second opening angle, and the distance between the first slot wall 114 and the second slot wall 125 is 31-34 mm. Preferably, the opening angle of the door body 500 is equal to the second opening angle, and the distance between the first slot wall 114 and the second slot wall 125 is 34 mm. In one embodiment of the present application, the door assembly further includes a second hinge 200, and the second hinge 200 is provided with a first shaft body 210 and a second shaft body 220, the first shaft body 210 is inserted in the first slot body 110, and the second shaft body 220 is inserted in the second slot body 120.

[0049] In one embodiment of the present application, the first slot body 110 includes a first slot portion 111 and a second slot portion 112 that are connected to each other, and the second slot body 120 includes a third slot portion 121, a fourth slot portion 122 and a fifth slot portion 123 that are connected in sequence. In an open state, the first shaft body 210 is located at an end of the second slot portion 112 away from the first slot portion 111, and the second shaft body 220 is located at an end of the fifth slot portion 123 away from the fourth slot portion 122; in a closed state, the first shaft body 210 is located at an end of the first slot portion 111 away from the second slot portion 112, and the second shaft body 220 is located at an end of the third slot portion 121 away from the fourth slot portion 122.

[0050] In some cases, the elliptical trajectory of the fourth groove portion satisfies the following relationship at any point (x, y) in the coordinate system:

[0051] x=M / sin(θ)*cos(90°-a-θ)-R*sin(a), y=M / sin(θ)*sin(90°-a-θ)

[0052] Wherein, x is the coordinate value of the arbitrary point on the first coordinate axis X, y is the coordinate value of the arbitrary point on the second coordinate axis Y, M is the absolute value of the coordinate of the starting point of the second axis on the first coordinate axis X, a is the opening angle of the door body, and θ is the angle between the major axis of the ellipse and the second coordinate axis Y. In the initial position, the first coordinate axis X is parallel to the front side of the door body, and the second coordinate axis Y is perpendicular to the front side.

[0053] In one embodiment of the present application, in the open state, the first axis 210 is located at the rear end of the first slot body 110, and the second axis 220 is located at the rear end of the second slot body 120; in the closed state, the first axis 210 is located at the front end of the first slot body 110, and the second axis 220 is located at the front end of the second slot body 120; there is a first gap 113 between the front end of the first slot body 110 and the first axis 210, and there is a second gap 124 between the front end of the second slot body 120 and the second axis 220, so that the door body can approach one side of the box body 400 to form a negative closing angle.

[0054] According to the refrigeration equipment of the embodiment of the present application, in the closed state, a first gap 113 is provided between the head end of the first slot body 110 and the first shaft body 210, and a second gap 124 is provided between the head end of the second slot body 120 and the second shaft body 220, thereby ensuring that the door body has a certain amount of space for movement. When an external force pushes the door body toward one side of the box body 400, the door body and the box body 400 form a negative closing angle, so that the door body can squeeze the seal, thereby improving the sealing of the refrigeration equipment.

[0055] It should be noted that in the normal closed state, the door body is parallel to one side of the box body 400, that is, the angle between the door body and one side of the box body 400 is zero. The negative closing angle formed between the door body and the box body 400 means that after the door body is in the closed state, it continues to approach the box body 400 under the action of external force, and the door body and one side of the box body 400 form an acute angle, and the acute angle is on the side of the box body 400 away from the door body.

[0056] In one embodiment of the present application, the maximum width of the first gap 113 is 0.5-4 mm, specifically, the maximum width of the first gap 113 is 1 mm, 2 mm, 3 mm or other sizes. The maximum width of the second gap 124 is 0.5-4 mm, specifically, the maximum width of the first gap 113 is 1 mm, 2 mm, 3 mm or other sizes.

[0057] It should be noted here that since the groove wall at the first end of the groove body is arc-shaped and the outer peripheral surface of the shaft body is arc-shaped, the maximum width of the utility model is the maximum value of the distance between the groove wall at the first end of the groove body and the outer peripheral surface of the shaft body.

[0058] In one embodiment of the present application, a buffer pad is provided on the groove wall of the third groove portion 121 away from the fourth groove portion 122 and the groove wall of the first groove portion 111 away from the second groove portion 112. The buffer pad is made of a flexible material, such as rubber or silicone. When the door body is in a closed state, in order to make the door body have a negative closing angle, there is a gap between the first shaft 210 and the groove wall of the first groove portion 111 away from the second groove portion 112. In order to prevent the door body from shaking, a buffer pad is provided on the groove wall of the first groove portion 111 away from the second groove portion 112. The buffer pad is in contact with the first shaft 210, which can prevent the door body from shaking and reduce the impact of the first shaft 210 on the groove wall of the first groove portion 111 away from the second groove portion 112 during the movement of the door body. Similarly, the role of the buffer pad provided on the groove wall of the third groove portion 121 away from the fourth groove portion 122 is the same as the above role.

Here, the fifth center line from the connection between the fifth center line and the fourth center line to the middle of the fifth center line is recorded as the first half of the fifth center line, and the distance between the first half of the fifth center line and the front side of the door body 500 gradually increases; the middle position of the fifth center line and the end of the fifth center line away from the fourth center line are recorded as the second half of the fifth center line, and the distance between the half of the fifth center line and the front side of the door body 500 gradually increases. The distance between one end of the second center line away from the first center line and the front side of the door body 500 is the maximum value of L2, and the difference range between L5 and the maximum value of L2 is 20-23mm, that is, the difference range between L5 and the distance between the end of the second center line away from the first center line in the thickness direction of the door body 500 and the front side of the door body 500 is 20-23mm. Specifically, the difference between L5 and the maximum value of L2 can be 20.2mm, 21.3mm, 22.5mm or other values.

[0078] At this stage, the distance between the first shaft body 210 and the second shaft body 220 in the thickness direction of the door body 500 increases first and then decreases. In this embodiment, the width of the first hinge 100 is determined by the difference between the maximum values ​​of L5 and L2, that is, the maximum distance between the first shaft body 210 and the second shaft body 220 in the thickness direction of the door body 500.

[0079] In one embodiment of the present application, Figures 4 to 6 As shown, during the opening process of the door body 500, the second shaft body 220 is suitable for moving around the second center of the circle with a third radius along the fifth trajectory in the fifth groove portion 123, and the first shaft body 210 is axially rotated at the end of the second groove portion 112 away from the first groove portion 111, that is, the first shaft body 210 slides relative to the second shaft body 220 along the arc-shaped fifth trajectory around the second center of the circle with a third radius; at the same time, the second shaft body 220 rotates around the first shaft body 210 with the center line of the first shaft body 210 as the center, and the first shaft body 210 is axially rotated at the end of the second groove portion 112 away from the first groove portion 111. Such a movement mode effectively reduces the distance that the hinged side of the door body 500 protrudes from the box body 400 during the opening process of the door body, so that the distance that the hinged side of the door body 500 protrudes from the box body 400 is less than or equal to 3 mm. Specifically, the distance that the hinged side of the door body 500 protrudes from the box body 400 is 2 mm, 2.5 mm or 2.6 mm. This greatly reduces the gap between the cabinet 300 and the box body 400, effectively improving the aesthetics of the refrigeration equipment after it is installed in the cabinet 300.

[0080] It should be noted here that the fifth track coincides with the fifth center line of the fifth groove portion 123 , and the fifth track extends along the fifth center line of the fifth groove portion 123 .

[0082] In one embodiment of the present application, the third groove portion 121 extends in an arc shape around the first center of the circle with a second radius, the second radius is greater than or equal to 20 mm, and the first radius is 21 mm, 22 mm, 23 mm or other values.

[0083] In one embodiment of the present application, the fourth groove portion 122 extends along the first ellipse, the fourth center line also extends along the first ellipse, and the fourth track also extends along the first ellipse.

[0084] In one embodiment of the present application, the second groove 112 extends along a straight line, and the second groove 112 extends along a tangent line at the connection between the first groove 111 and the second groove 112, so that the first shaft 210 can smoothly enter the second groove 112 from the first groove 111. Of course, the second groove 112 can also extend along a second ellipse.

[0085] In one embodiment of the present application, the width of the first groove portion 111 is the same as the width of the second groove portion 112, so that no matter whether the first shaft body 210 is in the first groove portion 111 or the second groove portion 112, the gap between the first shaft body 210 and the groove wall will not change, thereby improving the stability of the movement of the first shaft body 210 in the first groove body 110, avoiding the vibration of the door body 500 during the movement, and improving the user experience.

[0086] Furthermore, the connection between the first groove portion 111 and the second groove portion 112 is smoothed, that is, the groove wall at the connection between the first groove portion 111 and the second groove portion 112 is an arc surface, so that the first shaft body 210 can enter smoothly regardless of whether it enters from the first groove portion 111 to the second groove portion 112 or from the second groove portion 112 to the first groove portion 111, thereby reducing the impact between the first shaft body 210 and the groove wall.

[0087] In one embodiment of the present application, the width of the third groove portion 121 is the same as the width of the fourth groove portion 122. No matter whether the second shaft body 220 is in the third groove portion 121 or the fourth groove portion 122, the gap between the second shaft body 220 and the groove wall will not change, thereby improving the stability of the movement of the second shaft body 220 in the second groove body 120, avoiding the vibration of the door body 500 during the movement, and improving the user experience.

[0088] Furthermore, the connection between the third groove portion 121 and the fourth groove portion 122 is smoothed, that is, the groove wall at the connection between the third groove portion 121 and the fourth groove portion 122 is an arc surface, which allows the second shaft body 220 to enter smoothly regardless of whether it enters from the third groove portion 121 to the fourth groove portion 122 or from the fourth groove portion 122 to the third groove portion 121, thereby reducing the impact between the second shaft body 220 and the groove wall.

Since the edge of the first slot is provided with a first ridge and the edge of the second slot is provided with a second ridge, after the first shaft body 210 is inserted into the first slot body 110 and the second shaft body 220 is inserted into the second slot body 120, the second hinge 200 contacts the first ridge and the second ridge, thereby reducing the contact area between the first hinge 100 and the second hinge 200 and the friction between the first hinge 100 and the second hinge 200. When opening or closing the door body 500, only a very small force is required to push the door body 500 to rotate, thereby enhancing the user experience.

[0090] In one embodiment of the present application, based on the second groove portion 112 extending along a straight line, the second center line of the second groove portion 112 passes through the center of the first ellipse;
