DETAILED DESCRIPTION

[0038] The embodiments will be described in detail below with reference to examples thereof as shown in the accompanying drawings. When the following description refers to the drawings, same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following embodiments are not meant to represent all implementations consistent with the present application. Rather, they are merely examples of systems and methods consistent with some aspects of the present application as detailed in the appended claims.

[0039] In order to facilitate the opening or closing of the door body, a cross four-door and a double-door refrigerator will reserve a 20mm gap on both sides of the refrigerator. When the refrigerator is placed in cooperation with the cabinet or the refrigerator is embedded in the wall, the gap between the two sides of the refrigerator and the cabinet or the wall is too large, which will affect the appearance. At the same time, the smaller the gap between the refrigerator door body and the box body, the more beneficial to the improvement of the energy efficiency level of the refrigerator.

[0040] However, the smaller the gap between the refrigerator door body and the box body, the smaller the distance between the hinge on the refrigerator door body and the box body when the conventional single-axis refrigerator door body rotates, which is easy to interfere with the cabinet or the wall when the refrigerator door body rotates.

[0041] In order to solve the problem that when the embedded refrigerator is close to the wall, the wall easily interferes with the rotation of the door body, see Figure 1 The embodiment of the present application provides a hinge assembly applied to a refrigerator, the refrigerator comprising a box body 4 and a door body 5, and the hinge assembly comprising:

[0042] A first connecting plate 1, the first connecting plate 1 is connected with the box body 4;

[0043] The second connecting plate 2 is perpendicular to the first connecting plate 1, and the second connecting plate 2 is fixedly connected with the first connecting plate 1.

[0044] The first connecting plate 1 is provided with a plurality of screw holes, and the box body 4 is provided with screw holes at corresponding positions. After the first connecting plate 1 is aligned with the screw holes on the box body 4, the first connecting plate 1 and the box body 4 can be connected together through bolts. The box body 4 and the door body 5 are connected together through the hinge assembly 6. Therefore, the connection between the first connecting plate 1 and the second connecting plate 2 supports the door body 5. Therefore, the first connecting plate 1 and the second connecting plate 2 can be connected together by welding to improve the connection strength of the first connecting plate 1 or the second connecting plate 2. In addition, the first connecting plate 1 and the second connecting plate 2 can also be integrally formed, so that the connection between the first connecting plate 1 and the second connecting plate 2 is seamless, thereby improving the overall strength of the hinge assembly 6.

[0045] Since the uppermost end of the box body 4 is flush with the uppermost end of the door body 5 when the door body 5 is installed, the first connecting plate 1 is arranged perpendicular to the second connecting plate 2, so that the box body 4 is connected with the first connecting plate 1, and the door body 5 is connected with the second connecting plate 2 after the box body 4 and the door body 5 are connected together through the hinge assembly 6. The door body 5 is arranged in the correct position.

[0046] The guide block 3 is provided with a first track groove 31, a second track groove 33 and a connecting hole 32, as shown in Figure 3 The guide block 3 is connected with the door body 5.

[0047] The second connecting plate 2 is provided with a first connecting shaft 21, a fixed shaft 22, a connecting rod 23 and a second connecting shaft 24. One end of the connecting rod 23 is rotatably connected with the fixed shaft 22, and the other end of the connecting rod 23 is rotatably connected with the second connecting shaft 24.

[0048] The first connecting shaft 21 passes through the first track groove 31 and is slidably connected with the guide block 3. The second connecting shaft 24 is inserted into the connecting hole 32 and connected with the guide block 3.

[0049] During installation, one end of the first connecting shaft 21 can be inserted into the first track groove 31, and the second connecting shaft 24 is inserted into the connecting hole 32, so that the second connecting plate 2 is connected with the guide block 3. After the guide block 3 is connected with the door body 5, the box body 4 and the door body 5 can be connected together through the hinge assembly 6.

[0050] Since the embedded refrigerator needs to be embedded in the wall, when the distance between the two sides of the refrigerator and the wall is small, the edge of the door body 5 will contact the wall when the door body 5 is opened. Therefore, in the embodiment of the application, by arranging the first track groove 31, the first connecting shaft 21 moves and slides in the first track groove 31 during the rotation of the door body 5, and the second connecting shaft 24 is connected through the connecting rod 23 and the fixed shaft 22, so that the second connecting shaft 24 rotates around the connecting rod 23 as the radius and the fixed shaft 22 as the center during the rotation of the door body 5, so as to change the distance between the door body 5 and the wall, so as to prevent the edge of the door body 5 from contacting the wall when the door body 5 is opened.

[0051] For example, after the door body is connected with the box body through the hinge assembly, the maximum distance between the edge of the door body and the side of the box body during the rotation of the door body is 4 mm, and the minimum distance between the door body and the opening end of the box body is 5.5 mm. That is, when the refrigerator is embedded in the wall or the cabinet, the distance between the box body of the refrigerator and the wall is at least 4 mm. In some embodiments, the first track groove 31 includes a first circular arc groove 311 and a second circular arc groove 312, the opening direction of the first circular arc groove 311 is opposite to the opening direction of the second circular arc groove 312, and the opening direction of the first circular arc groove 311 is towards the box body 4.

[0052] The first circular arc groove 311 and the second circular arc groove 312 are arc-shaped, the arc-shaped track groove can provide a smooth transition path for the movement of the door body 5, the first connecting shaft 21 moves smoothly in the first track groove 31, avoiding the sudden turning or stopping caused by the straight track groove, which affects the smoothness of the opening or closing process of the door body 5. In addition, the design of the arc-shaped first track groove 31 helps to reduce the friction between the first connecting shaft 21 and the first track groove 31 during the movement of the door body 5, thereby reducing wear and noise.

[0053] At the same time, by arranging the opening direction of the first circular arc groove 311 opposite to the opening direction of the second circular arc groove 312, the first connecting shaft 21 can smoothly transition from one circular arc groove to another circular arc groove during the rotation of the door body 5 to different angles. This helps to ensure that the first connecting shaft 21 can move smoothly along the predetermined track during the opening or closing process of the door body 5, avoiding the occurrence of jamming or unsmoothness.

[0054] There is an included angle between the door body 5 and the box body 4, for example, when the door body 5 is closed, the included angle between the door body 5 and the box body 4 is 0°, so that when the door body 5 rotates from the closed state to the open state, the first connecting shaft 21 will slide in the first track groove 31, and the position of the first connecting shaft 21 changes when the included angle between the door body 5 and the box body 4 changes.

[0055] Specifically, as shown in FIG. 6, the first track groove 31 includes a first circular arc groove 311 and a second circular arc groove 312, the opening direction of the first circular arc groove 311 is opposite to the opening direction of the second circular arc groove 312, and the opening direction of the first circular arc groove 311 is towards the box body 4. Figure 4As shown, the first circular arc groove 311 includes a first end 313 and a second end 314, and the second circular arc groove 312 includes a third end 315 and a fourth end 316, and the second end 314 coincides with the third end 315; when the door body 5 is in the closed state, the fixed shaft 22 is arranged at the fourth end 316, and the first connecting shaft 21 is arranged between the first end 313 and the second end 314.

[0056] As shown in FIG. 2, when the door body 5 is in the closed state, the first connecting shaft 21 is arranged between the first end 313 and the second end 314 of the first circular arc groove 311. Figure 5 As shown in FIG. 3, when the door body 5 rotates from the closed state to the open state, the first connecting shaft 21 moves from the second end 314 to the first end 313, and when the first connecting shaft 21 abuts against the first end 313, the angle between the door body 5 and the cabinet 4 is a first angle.

[0057] As shown in FIG. 4, when the door body 5 rotates from the first angle to a second angle, the first connecting shaft 21 moves from the first end 313 to the second end 314; the second angle is 90°. Figure 6 As shown in FIG. 5, when the door body 5 rotates from the second angle to a third angle, the first connecting shaft 21 moves from the third end 315 to the fourth end 316, and when the first connecting shaft 21 abuts against the fourth end 316, the angle between the door body 5 and the cabinet 4 is the third angle.

[0058] Figure 7 Specifically, when the door body 5 rotates from the closed state to the open state, in order to avoid the edge of the door body 5 from contacting the wall, the first connecting shaft 21 moves from the second end 314 to the first end 313 to reduce the rotation radius of the door body 5 when rotating, so that the door body 5 is away from the wall and will not be away from the cabinet 4 during the rotation process, and when the first connecting shaft 21 abuts against the first end 313, a specific angle between the door body 5 and the cabinet 4 is formed, that is, the first angle, at this time, the rotation radius of the door body 5 is the smallest. For example, the first angle is 30°, that is, when the door body 5 rotates by 30°, the first connecting shaft 21 abuts against the first end 313.

[0059] With further rotation of the door body 5, when the door body 5 continues to rotate from the first angle to the second angle (90°), the first connecting shaft 21 again moves from the first end 313 to the second end 314. Finally, during the process that the door body 5 rotates from the second angle to the third angle, the first connecting shaft 21 moves from the third end 315 to the fourth end 316 until the first connecting shaft 21 abuts against the fourth end 316, at this time, the angle between the door body 5 and the cabinet 4 is the third angle, for example, the third angle is 130°, when the door body 5 rotates to 130°, the first connecting shaft 21 abuts against the fourth end 316. It can be understood that the third angle is the maximum opening angle of the door body 5, at this time, the side of the door body 5 away from the cabinet 4 abuts against the wall.

[0060] With further rotation of the door body 5, when the door body 5 continues to rotate from the first angle to the second angle (90°), the first connecting shaft 21 again moves from the first end 313 to the second end 314. Finally, during the process that the door body 5 rotates from the second angle to the third angle, the first connecting shaft 21 moves from the third end 315 to the fourth end 316 until the first connecting shaft 21 abuts against the fourth end 316, at this time, the angle between the door body 5 and the cabinet 4 is the third angle, for example, the third angle is 130°, when the door body 5 rotates to 130°, the first connecting shaft 21 abuts against the fourth end 316. It can be understood that the third angle is the maximum opening angle of the door body 5, at this time, the side of the door body 5 away from the cabinet 4 abuts against the wall.

[0061] ​In addition, since the second connecting shaft 24 is arranged in the connecting hole 32, the fixed rotating radius of the second connecting shaft 24 can limit the movement of the first connecting shaft 21 during the movement of the first connecting shaft 21, and prevent the door body 5 from colliding with the wall due to the rapid sliding of the first connecting shaft 21 in the first track groove 31.

[0062] In some embodiments, as shown in Figure 2 and Figure 3 The hinge assembly provided by the embodiments of the present application is applied to a refrigerator, and the refrigerator comprises a cabinet 4 and a door body 5. The hinge assembly comprises:

[0063] A first connecting plate 1, which is connected with the cabinet 4;

[0064] A second connecting plate 2, which is perpendicular to the first connecting plate 1 and is fixedly connected with the first connecting plate 1;

[0065] A guide block 3, as shown in Figure 3 The guide block 3 is provided with a first track groove 31, a second track groove 33 and a guide block 32. The guide block 3 is connected with the door body 5;

[0066] The second connecting plate 2 is provided with a first connecting shaft 21 and a third connecting shaft 25. The first connecting shaft 21 penetrates through the first track groove 31 and is slidably connected with the guide block 3. The third connecting shaft 25 penetrates through the second track groove 33 and is slidably connected with the guide block 3.

[0067] The position of the third connecting shaft 25, the position of the second track groove 33 and the shape of the second track groove 33 need to be accurately set. Specifically, in some embodiments, the position of the third connecting shaft 25 is the first position, the standard point of the connecting line between the axis center of the second connecting shaft 24 and the axis center of the fixed shaft 22 in the closed state of the door body 5 is the second position, and the first position coincides with the second position. The shape of the second track groove 33 is the same as the moving track shape of the standard point when the door body 5 rotates from the closed state to the third included angle. It can be understood that the first position of the third connecting shaft 25, in the closed state of the door body 5, any point on the connecting line between the axis center of the second connecting shaft 24 and the axis center of the fixed shaft 22 can be used. During the opening process of the door body 5, by recording the moving track shape of the standard point, the shape and position of the second track groove 33 are set as the moving track shape and position of the standard point, that is, the second track groove 33 is obtained. The third connecting shaft 25 is arranged in the second track groove 33. When the door body 5 rotates from the closed state to the maximum opening angle, the moving path of the first connecting shaft 21 in the first track groove 31 is the same as the moving path of the first connecting shaft 21 in the first track groove 31 when the second connecting shaft 24 is arranged. Therefore, both types of hinge assemblies 6 can realize the effect of the variable track movement of the door body 5. When the refrigerator is embedded in the wall, the problem that the wall easily interferes with the rotation of the door body 5 when the door body 5 is close to the wall is solved.

[0068] In some embodiments, as shown in Figure 3 The guiding block 3 is connected with the door body 5.

[0069] The first track groove 31, the connecting hole 32 and the second track groove 33; the guiding block 3 is connected with the door body 5.

[0070] When applied to the hinge assembly provided with the second connecting shaft 22, the first connecting shaft 21 is slidably connected with the guiding block 3 through the first track groove 31; the second connecting shaft 24 is connected with the guiding block 3 by being inserted into the connecting hole 32.

[0071] When applied to the hinge assembly provided with the third connecting shaft 25, the first connecting shaft 21 is slidably connected with the guiding block 3 through the first track groove 31; the third connecting shaft 25 is slidably connected with the guiding block 3 through the second track groove 33.

[0072] By arranging the guiding block 3 suitable for two different types of hinge assemblies, the versatility of the guiding block 3 is improved.

[0073] According to the technical scheme, the hinge assembly and the guide block are provided, the hinge assembly comprises: a first connecting plate 1 connected with a box body 4; a second connecting plate 2 perpendicular to the first connecting plate 1, and fixedly connected with the first connecting plate 1; a guide block 3 provided with a first track groove 31 and a connecting hole 32; the guide block 3 is connected with a door body 5; the second connecting plate 2 is provided with a first connecting shaft 21, a fixed shaft 22, a connecting rod 23 and a second connecting shaft 24, one end of the connecting rod 23 is rotatably connected with the fixed shaft 22, the other end of the connecting rod 23 is rotatably connected with the second connecting shaft 24; the first connecting shaft 21 is slidably connected with the guide block 3 through the first track groove 31; and the second connecting shaft 24 is connected with the guide block 3 by being inserted into the connecting hole 32. By arranging the first track groove 31 on the guide block 3, during opening and closing of the door body 5, the first connecting shaft 21 slides in the first track groove 31, so that the distance between the door body 5 and the box body 4 is changed, and the door body 5 is prevented from contacting the wall body during rotation, so as to solve the problem that when the door body 5 of the built-in refrigerator is close to the wall body, the wall body easily interferes with rotation of the door body 5.

[0074] The similar parts among the embodiments provided in the application can be referred to each other, the specific embodiments provided above are only several examples under the general concept of the application, and do not limit the protection scope of the application. Any other embodiments extended according to the application scheme without creative labor belong to the protection scope of the application.
