[0052] As shown in Figures 1 to 2, the hinge assembly includes a first hinge 100 and a second hinge 200. The first hinge 100 is provided with a first slot 110 and a second slot 120; the second hinge 200 is provided with a first shaft 210 and a second shaft 220. The first shaft 210 is inserted into the first slot 110 and is suitable for moving relative to the first slot 110 along a first track and a second track in the first slot 110; the second shaft 220 is inserted into the second slot 120 and is suitable for moving relative to the second slot 120 along a third track and a fourth track in the second slot 120. The first track extends along an arc shape around a first center of a circle (Q1 in Figure 2) with a first radius (R1 in Figure 2), the second track is connected to the first track, and the fourth track is connected to the third track; one of the first hinge 100 and the second hinge 200 is fixed to the hinge side of the door body 500;

[0053] During the opening process of the door body 500, the first shaft body 210 approaches the second shaft body 220 along the first trajectory, and the distance between the first shaft body 210 and the second shaft body 220 in the thickness direction of the door body 500 varies in the range of 0.8-8 mm. Specifically, the distance between the first shaft body 210 and the second shaft body 220 in the thickness direction of the door body 500 is 2.5 mm, 3 mm, or 4 mm. The first shaft body 210 moves away from the first trajectory along the second trajectory, and the distance between the first shaft body 210 and the second shaft body 220 in the thickness direction of the door body 500 gradually increases. The distance between the first shaft body 210 and the second shaft body 220 in the thickness direction of the door body 500 varies in the range of 8-23 mm. Specifically, the distance between the first shaft body 210 and the second shaft body 220 in the thickness direction of the door body 500 is 8 mm, 12 mm, or 16 mm.

[0054] According to the hinge assembly of the embodiment of the present application, since during the opening process of the door body 500, the first axis 210 moves along the first track and the second track, and the second axis 220 moves along the third track and the fourth track, the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body 500 gradually increases, and the maximum distance between the first axis 210 and the second axis 220 in the thickness direction of the door body 500 is 8-23mm, which allows the hinge assembly to be made narrower and can be well adapted to thin door bodies.

[0055] The front side of the door body is also the front side of the door body 500. For the convenience of description, the front side of the door body will be referred to as the front side of the door body 500 in the following.

[0056] In the present application, the movement of the first axis 210 relative to the first groove body 110 and the movement of the second axis 220 relative to the second groove body 120 can be that the first hinge 100 moves and the second hinge 200 is stationary, or the first hinge 100 is stationary and the second hinge 200 moves; preferably, the first hinge 100 moves and the second hinge 200 is stationary.

[0057] The thickness direction of the door body is also the thickness direction of the door body 500. For the convenience of description, the thickness direction of the door body will be referred to as the thickness direction of the door body 500 in the following.

[0058] The distance between the first shaft body 210 and the second shaft body 220 in the thickness direction of the door body 500 is the distance between the central axis of the first shaft body 210 and the central axis of the second shaft body 220 in the thickness direction of the door body 500 .

[0059] As shown in Figure 7, since the front side of the door body 500 is flush with the side of the first hinge 100 close to the first hinge 100, when it is necessary to calculate the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body, first make a first straight line passing through the center of the first axis 210 and parallel to the front side of the door body, and then make a second straight line passing through the center of the second axis 220 and parallel to the front side of the door body. Finally, measure the distance between the first straight line and the second straight line to obtain the distance L between the first axis 210 and the second axis 220 in the thickness direction of the door body.

[0060] In one embodiment of the present application, the first axis 210 approaches the second trajectory along the first trajectory, and the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body first gradually decreases and then gradually increases; based on the gradual decrease in the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body, the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body varies in a range of 0-2.5mm; based on the gradual increase in the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body, the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body varies in a range of 0-8mm.

[0061] In one embodiment of the present application, when the door body is in a closed state, the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body is 0.8-2.5 mm. Specifically, the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body is 1 mm, 1.5 mm, 2 mm or other sizes. Preferably, when the door body is in a closed state, the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body is 1.2 mm.

[0062] In one embodiment of the present application, when the first shaft 210 is in the open state, the distance between the first shaft 210 and the second shaft 220 in the thickness direction of the door body is 18-23 mm. Specifically, the distance between the first shaft 210 and the second shaft 220 in the thickness direction of the door body is 19 mm, 20 mm, 21 mm, or other sizes. In one embodiment of the present application, the third trajectory extends along an arc around the first center of the circle with a second radius (R2 in Figure 2), and the fourth trajectory extends along the first ellipse.

[0063] As shown in FIG3 , when the door body is in the closed position, the distance between the first shaft body 210 and the second shaft body 220 in the thickness direction of the door body is L1 , and the value of L1 is relatively small at this time.

[0064] As shown in FIG4 , when the door is opened to 25°, the distance between the first shaft 210 and the second shaft 220 in the thickness direction of the door body is L2. At this time, the value of L2 increases, and L2 is greater than L1.

[0065] As shown in FIG5 , when the door is opened to 70°, the distance between the first shaft 210 and the second shaft 220 in the thickness direction of the door body is L3. At this time, the value of L3 is further increased compared to L2.

[0066] In one embodiment of the present application, the first hinge 100 is a block-shaped structure and is fixed to the hinged side of the door body, wherein one first hinge 100 is provided at the upper portion of the hinged side of the door body, and another first hinge 100 is provided at the lower portion of the hinged side of the door body. Furthermore, the hinged side of the door body is provided with a mounting groove, and the first hinge 100 is embedded in the mounting groove and secured using a fastener, which is a screw or bolt. Of course, a snap fastener can also be used to secure the first hinge 100 to the mounting groove.

[0067] In one embodiment of the present application, the first hinge 100 has a first side and a second side relative to each other, the first groove body 110 and the second groove body 120 are located on the first side of the first hinge 100, and the second side of the first hinge 100 is provided with at least one positioning hole, and the bottom of the mounting groove is provided with at least one positioning column. When the first hinge 100 is embedded in the mounting groove, the positioning column is inserted into the positioning hole to fix the first hinge 100.

[0068] In one embodiment of the present application, the second hinge 200 has a sheet-like structure, and the first shaft 210 and the second shaft 220 are perpendicularly arranged on the side of the second hinge 200 facing the first hinge 100. Specifically, the second hinge 200 is provided with two through holes, and the first shaft 210 and the second shaft 220 are respectively inserted into the two through holes. Of course, the second hinge 200 can also be welded to the first shaft 210 and the second shaft 220 or integrally formed. The second hinge 200 is also provided with a connecting portion for connecting to the box body. Specifically, the connecting portion is provided with a through hole, and the connecting portion is connected to the box body via rivets or screws in the through hole.

[0069] 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. The first track is located in the first slot portion 111. Specifically, the first track is located on the center line of the first slot portion 111 and extends along the length of the center line of the first slot portion 111. The second track is located in the second slot portion 112. Specifically, the second track is located on the center line of the second slot portion 112 and extends along the length of the center line of the first slot portion 111.

[0070] 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. This ensures that the gap between the first shaft body 210 and the groove wall will not change whether the first shaft body 210 is in the first groove portion 111 or the second groove portion 112, thereby improving the stability of the first shaft body 210 during the movement process in the first groove body 110, avoiding vibration during the movement of the door body, and improving the user experience.

[0071] The width of the groove portion refers to the distance between two opposite groove walls perpendicular to the center line of the groove portion.

[0072] 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, which allows the first shaft body 210 to 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 collision between the first shaft body 210 and the groove wall.

[0073] In one embodiment of the present application, the second slot body 120 includes a third slot portion 121 and a fourth slot portion 122 that are connected. The third track is located in the third slot portion 121. Specifically, the third track is located on the center line of the third slot portion 121 and extends along the length of the center line of the third slot portion 121. The fourth track is located in the fourth slot portion 122. Specifically, the third track is located on the center line of the third slot portion 121 and extends along the length of the center line of the third slot portion 121.

[0074] 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. This ensures that 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 second shaft body 220 during the movement process in the second groove body 120, avoiding vibration during the movement of the door body, and improving the user experience.

[0075] 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 collision between the second shaft body 220 and the groove wall.

[0076] In one embodiment of the present application, the second slot 120 further includes a fifth slot 123. The fifth slot 123 is disposed at an end of the fourth slot 122 distal from the third slot 121 and communicates with the fourth slot 122. The fifth slot 123 extends in an arc shape around the second center (Q2 in FIG. 2 ) at a third radius (R3 in FIG. 2 ). The second shaft 220 is adapted to move within the fifth slot 123 along a fifth trajectory around the second center at the third radius, with the fifth trajectory connecting to the fourth trajectory.

[0077] Furthermore, the width of the fifth groove portion 123 is the same as the width of the fourth groove portion 122 , and the groove wall at the connection between the fifth groove portion 123 and the fourth groove portion 122 is an arc surface.

[0078] In one embodiment of the present application, during the opening process of the door body 500, the second shaft body 220 is suitable for moving along the fifth trajectory in the fifth groove portion 123 around the second center of the circle with a third radius, and the first shaft body 210 rotates axially 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 rotates axially at the end of the second groove portion 112 away from the first groove portion 111. This movement method 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.

[0079] 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 .

[0080] In one embodiment of the present application, during the opening process of the door body, the second axis 220 moves along the fifth track in the direction away from the fourth track, and the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body first increases and then decreases. The distance between the first axis 210 and the second axis 220 in the thickness direction of the door body varies in the range of 20-23 mm. Specifically, the distance between the first axis 210 and the second axis 220 in the thickness direction of the door body is 14.2 mm, 14.3 mm, 14.5 mm or other values.

[0081] As shown in FIG6 , when the door is opened to 100 degrees, the distance between the first shaft 210 and the second shaft 220 in the thickness direction of the door body is L4, and at this time, L4 first increases and then decreases.

[0082] During this stage, the distance between the first shaft 210 and the second shaft 220 in the thickness direction of the door body 500 first increases and then decreases. In this embodiment, the width of the first hinge 100 is determined by the distance between the first shaft 210 and the second shaft 220 in the thickness direction of the door body 500, that is, the maximum distance between the first shaft 210 and the second shaft 220 in the thickness direction of the door body 500.

[0083] In one embodiment of the present application, as shown in FIG1 , a first slot body 110 is formed on a first side of a first hinge member 100, communicating with the first slot body 110. A first ridge is provided on the edge of the first slot, surrounding the edge of the first slot, and the shape formed by the first ridge is the same as the shape of the first slot. A second slot body 120 is formed on a first side of the first hinge member 100, communicating with the second slot body 120. A second ridge is provided on the edge of the second slot, surrounding the edge of the second slot, and the shape formed by the second ridge is the same as the shape of the second slot. 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 210 is inserted into the first slot 110 and the second shaft 220 is inserted into the second slot 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.

[0084] In one embodiment of the present application, the second center is located on the first center line of the first slot body 110 , that is, the second center is located on the second track, and the distance between the second center and the center line of the fifth slot portion 123 is R3.

[0085] In one embodiment of the present application, the first groove portion 111 extends in an arc shape around the first center with a first radius, and the first radius is greater than or equal to 5 mm, and the first radius is 6 mm, 7 mm, 8 mm or other values.

[0086] In one embodiment of the present application, the third groove portion 121 extends in an arc shape around the first center 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.

[0088] In some cases, the elliptical trajectory of the fourth groove portion satisfies the following relationship at any point (x, y) in the coordinate system:

[0089] x=M / sin(θ)*cos(90°-a-θ)-R*sin(a), y=M / sin(θ)*sin(90°-a-θ)

[0090] Where 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 coordinate value 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.

[0091] 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. This allows the first shaft 210 to smoothly enter the second groove 112 from the first groove 111. Of course, the second groove 112 can also extend along a second ellipse.

[0092] In one embodiment of the present application, based on the second groove portion 112 extending along a straight line, the first center line of the second groove portion 112;

[0093] Alternatively, since the second groove 112 extends along the second ellipse, the center of the second ellipse coincides with the center of the first ellipse.

[0094] In one embodiment of the present application, the door body is suitable for switching between an open state and a closed state. In the open state, the opening angle of the door body is less than or equal to a first opening angle, and the first axis 210 is located in the first groove 111 and the second axis 220 is located in the third groove 121; the first opening angle is greater than or equal to 10° and less than or equal to 50°, specifically, the first opening angle is 24°, 25°, 26° or other angles.

[0095] In one embodiment of the present application, the opening angle of the door body 500 is greater than the first opening angle and less than or equal to the second opening angle, the first axis 210 is located in the second groove 112 and the second axis 220 is located in the fourth groove 122, the second opening angle is greater than or equal to 60° and less than or equal to 95°, specifically, the second opening angle is 70°, 80°, 90° or other angles.

[0096] In one embodiment of the present application, the opening angle of the door body 500 is greater than the second opening angle and less than or equal to the third opening angle, the second axis 220 is located in the fifth groove 123 and the first axis 210 is located in the second groove 112, and the third opening angle is greater than or equal to 100° and less than or equal to 150°. Specifically, the third opening angle is 110°, 120°, 130° or other angles.

[0097] In one embodiment of the present application, the curvature radius of the fourth groove portion 122 gradually increases in a direction away from the third groove portion 121 , and the curvature radius of the fifth groove portion 123 is smaller than the curvature radius of the third groove portion 121 .

[0098] In one embodiment of the present application, the curvature radius of the third groove portion 121 is greater than or equal to the first preset curvature radius; the curvature radius of the fifth groove portion 123 is less than or equal to the second preset curvature radius, and the second preset curvature radius is smaller than the first preset curvature radius.

[0099] Since the connection points of the third groove portion 121, the fourth groove portion 122 and the fifth groove portion 123 are all tangent, the curvature radius of the end end of the third groove portion 121 is equal to the curvature radius of the starting end of the fourth groove portion 122, that is, the end end of the third groove portion 121 is the starting end of the fourth groove portion 122, and then the curvature radius of the fourth groove portion 122 close to the third groove portion 121 is smaller than the first preset curvature radius, so that the third groove portion 121 gradually transitions to the fourth groove portion 122 in a circular arc, ensuring that the door opening process is more stable and avoiding jamming.

[0100] Likewise, the curvature radius of the ending end of the fourth groove portion 122 is the same as the curvature radius of the starting end of the fifth groove portion 123 .

[0101] In some embodiments of the present application, the first preset curvature radius is R1, wherein 30mm≤R1≤34mm, that is, the value of R1 can be any integer between 30mm and 34mm, that is, 30mm, 31mm, 32mm, 33mm or 34mm, and the value of R1 can also be any rational number between 30mm and 34mm, that is, 30.1mm, 32.65mm or 33.52mm, etc. Preferably, the first preset curvature radius R1 is 32mm.

[0102] The third preset curvature radius is R3, where 10mm≤R2≤14mm, that is, the value of R3 can be any integer between 12mm and 14mm, that is, 10mm, 11mm, 12mm, 13mm or 14mm. The value of R3 can also be any rational number between 10mm and 14mm, that is, 10.1mm, 12.65mm or 13.52mm, etc. Preferably, the first preset curvature radius R3 is 12mm.

[0103] In some embodiments of the present application, as shown in FIG2 , in the closed state, a first gap is provided between the first shaft 210 and the groove wall of the first groove portion 111 away from the second groove portion 112, and a second gap is provided between the second shaft 220 and the groove wall of the third groove portion 121 away from the fourth groove portion 122. The width of the first gap is 0.5-4 mm, and the width of the second gap is 0.5-4 mm. By providing a first gap between the head end of the first groove portion 110 and the first shaft 210, and a second gap between the head end of the second groove portion 120 and the second shaft 220 in the closed state, it is ensured 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 cabinet 400, the door body and the cabinet 400 form a negative closing angle, so that the door body can squeeze the seal, thereby improving the sealing performance of the refrigeration equipment.

[0104] A second aspect of the present application provides a door component, comprising a door body 500 and a hinge assembly as described in any one of the above embodiments, wherein one of the first hinge and the second hinge is fixed to a hinge side of the door body 500 .

[0105] In one embodiment of the present application, the thickness of the door body 500 is greater than or equal to 15 mm and less than or equal to 35 mm. Specifically, the thickness of the door body 500 is 25 mm, 30 mm, 32 mm or other sizes.

[0106] As shown in Figures 7 to 9, the third aspect of the present application provides a refrigeration device, including a box body 400, a door body 500 and the hinge assembly described in any one of the above embodiments, one of the first hinge 100 and the second hinge is fixed to the hinge side of the door body 500, the other of the first hinge 100 and the second hinge is arranged on the box body 400, and the box body 400 and the door body 500 are hinged through the first hinge 100 and the second hinge.

[0107] By adopting the above hinge assembly, the thickness of the door component can be effectively reduced, the volume of the refrigeration equipment can be reduced, and the competitiveness of the product can be enhanced.
