Description

Technical Field

[0001] This invention relates to a hinge assembly, and more particularly to a refrigeration device including the hinge assembly. Background Technology

[0002] In refrigerators and other refrigeration equipment, the door and cabinet are connected by hinge assemblies. Traditional hinge assemblies require precise alignment during installation to ensure the door rotates along the intended axis and closes tightly without leakage. Furthermore, the hinge structure must be designed to prevent loosening, instability, or misalignment during long-term use. These problems will affect the refrigerator door's sealing performance and user experience, negatively impacting the overall performance of the refrigeration equipment. Therefore, there is still room for improvement in the structural design and installation efficiency of current hinge assemblies. Summary of the Invention

[0003] To address the problem of complex installation of hinge components in the prior art, the present invention aims to provide a hinge component that improves the ease of installation and the reliability of use, as well as a refrigeration device including the hinge component.

[0004] To achieve the above-mentioned objective, one embodiment of the present invention provides a hinge assembly, including a housing connection portion and a door connection portion. The door connection portion includes a through hole. The housing connection portion includes a fixing member, a rotating member, and an elastic member. The fixing member includes a fixing boss. The rotating member is rotatably connected to the fixing member, and its rotation range is between a misaligned position and an aligned position. At the misaligned position, the rotating member is misaligned with the fixing member. At the aligned position, the rotating member is aligned with the fixing member. The elastic member drives the rotating member to maintain the rotating member at the misaligned position.

[0005] When the door connecting part is connected to the box connecting part, the door connecting part drives the rotating member to rotate from the misaligned position to the aligned position, the through hole passes through the rotating member, the fixed boss is located in the through hole, and the door connecting part and the box connecting part are fixed relative to each other.

[0006] As a further improvement of the present invention, the cross-section of the through hole is set as an irregular hole, and the cross-section of the fixing boss matches the shape of the cross-section of the through hole;

[0007] At the alignment position, the cross-section of the through hole completely covers the cross-section of the rotating component;

[0008] At the misaligned position, the cross-section of the through hole covers at most a portion of the cross-section of the rotating member.

[0009] As a further improvement of the present invention, the housing connection portion further includes a first adjustment portion and a second adjustment portion. The first adjustment portion adjusts the movement of the fixing member in a first direction, and the second adjustment portion adjusts the movement of the fixing member in a second direction. On a plane perpendicular to the installation direction of the door connection portion toward the housing connection portion, the first direction is perpendicular to the second direction.

[0010] As a further improvement of the present invention, the first adjusting part includes a first adjusting bolt, a first tilting member and a first positioning member. The first adjusting bolt is rotatably connected to the first positioning member along the installation direction. The first adjusting bolt and the first tilting member are relatively fixed along the installation direction. The fixing member includes a first tilting groove. The first tilting member is disposed in the first tilting groove. When the first adjusting bolt moves along the installation direction, the first tilting member abuts against the fixing member and moves in the first direction.

[0011] As a further improvement of the present invention, the second adjusting part includes a second adjusting bolt, a second tilting member and a second positioning member. The second adjusting bolt is rotatably connected to the second positioning member along the installation direction. The second adjusting bolt and the second tilting member are relatively fixed along the installation direction. The fixing member includes a second tilting groove. The second tilting member is disposed in the second tilting groove. When the second adjusting bolt moves along the installation direction, the second tilting member abuts against the fixing member and moves in the second direction.

[0012] As a further improvement of the present invention, the cross-section of the through hole and the cross-section of the fixing boss are both set to square. The fixing boss includes two first sidewalls and two second sidewalls. The two first sidewalls and the two second sidewalls are arranged opposite to each other. The plane where the first sidewall is located is perpendicular to the first direction, and the plane where the second sidewall is located is perpendicular to the second direction.

[0013] As a further improvement of the present invention, the door connecting portion further includes a plurality of adjustment holes, the first adjusting portion being aligned with one of the adjustment holes, the second adjusting portion being aligned with the other adjustment hole, the adjustment holes being used to adjust the first adjusting portion and / or the second adjusting portion through the adjustment holes from the outside of the box connecting portion, so as to move the fixing member in the first direction and / or the second direction.

[0014] As a further improvement of the present invention, the rotating member is configured as a conical member, and the cross-sectional area of ​​the rotating member gradually increases in the mounting direction of the door connecting part toward the box connecting part; from the misaligned position to the aligned position, the rotating member rotates 90°, and when the fixed boss is located in the through hole, the elastic member drives the rotating member back to the misaligned position.

[0015] To achieve one of the above-mentioned objectives, an embodiment of the present invention provides a refrigeration device, including a housing, a door, and the aforementioned hinge assembly, wherein the door connecting part is rotatably connected to the door, and the housing connecting part is fixedly connected to the housing.

[0016] As a further improvement of the present invention, the box body includes a box shell, the box shell includes an opening, the fixing member is at least partially fixed inside the box shell, the fixing boss and the rotating member are exposed outside the box shell through the opening, and the cross-section of the opening matches the cross-sectional shape of the fixing boss.

[0017] Compared with the prior art, the present invention has the following beneficial effects: During installation, the improved hinge assembly only requires pressing down the door connecting part to drive the rotating part to rotate from the misaligned position to the aligned position. Then, under the action of the elastic element, it automatically returns to the aligned position, thus completing the relative fixation of the door connecting part and the box connecting part. This achieves the effect of automatic alignment and stable fixation. This design not only simplifies the installation steps and improves the installation efficiency, but also reduces the complexity of alignment adjustment. Furthermore, due to its good alignment effect, it can maintain the stable connection and reliable use of the door during long-term use, thus improving the user experience.

Detailed Implementation

[0030] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0031] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0032] One embodiment of the present invention provides a hinge assembly that improves the ease of installation and the reliability of use, as well as a refrigeration device including the hinge assembly.

[0033] The refrigeration equipment in this embodiment can be a refrigerator, freezer, upright refrigerator, wine cabinet, etc. The refrigeration equipment in the following embodiment is described using a refrigerator as an example. The refrigerator includes a cabinet 200 and a door 300. The door 300 and the cabinet 200 enclose a refrigeration space, which includes a refrigerator compartment, a freezer compartment, a variable temperature compartment, etc. The refrigerator also includes a hinge assembly 100, and the door 300 is rotatably connected to the cabinet 200 through the hinge assembly 100.

[0034] like Figure 1 and2 As shown, the hinge assembly 100 includes a housing connecting part 10 and a door connecting part 20. The door connecting part 20 is rotatably connected to the door 300, and the housing connecting part 10 is fixedly connected to the housing 200. Figures 3-6 As shown, the box body 200 includes a box shell 201, the box shell 201 includes an opening 202, and the box body connecting part 10 is fixedly connected at the opening 202.

[0035] The door connecting part 20 includes a through hole 21, and the box connecting part 10 includes a fixing member 11, a rotating member 12, and an elastic member 13. The fixing member 11 includes a fixing boss 111, and the rotating member 12 is rotatably connected to the fixing member 11. Its rotation range is between a misaligned position and an aligned position. In the misaligned position, the rotating member 12 is misaligned with the fixing member 11. The misaligned position is as follows: Figure 6 , 7 As shown in Figure 11; at the alignment position, the rotating member 12 is aligned with the fixed member 11, and the alignment position is as follows. Figure 2 , 10 As shown in the figure, the rotating part 12 rotates from the misaligned position to the aligned position, with a rotation range of approximately 90°.

[0036] At the aligned position, the rotating member 12 is aligned with the fixed member 11. At the misaligned position, the rotating member 12 is misaligned with the fixed member 11. The cross-section of the through hole 21 covers at most part of the cross-section of the rotating member 12. Here, the cross-sectional shape of the rotating member 12 and the fixed member 11 is basically the same. They are aligned at the aligned position. Since the rotating member 12 is misaligned with the fixed member 11 after rotation, the cross-sections of the rotating member 12 and the fixed member 11 that can be aligned are not circular shapes that are always aligned in any direction of 360°. Instead, they are shapes that can be misaligned, such as square, waist-shaped, elliptical, or triangular.

[0037] Without any other external force, the elastic element 13 drives the rotating element 12 to remain in the misaligned position. The elastic element 13 applies a force to the rotating element 12 to make it tend to remain in the misaligned position. When the external force is greater than the elastic force of the elastic element 13, it drives the rotating element 12 to rotate in the direction of alignment.

[0038] When the door connecting part 20 is connected to the cabinet connecting part 10, that is, when the refrigeration equipment is installed, the door connecting part 20 is fixed to the door 300 and the cabinet connecting part 10 is fixed to the cabinet 200. At this time, the door connecting part 20 drives the rotating part 12 to rotate from the misaligned position to the aligned position. The through hole 21 passes through the rotating part 12, and the fixing boss 111 is located in the through hole 21. The door connecting part 20 and the cabinet connecting part 10 are fixed relative to each other.

[0039] To clearly illustrate the positions and directions described in this embodiment, the reference gravity direction is defined as "down" and the opposite direction as "up." The refrigerator is placed on a horizontal surface. When the door 300 is closed, it is located in front of the cabinet 200, and the opposite direction is "rear." The left and right sides of the plane containing the up, down, front, and back are respectively the left and right sides. This embodiment... Figure 1 , Figure 3 , Figure 5 The hinge assembly 100 in the figure is the upper hinge of the upper left door body 300. The hinge assembly 100 in the figure is located on the left side of the door body 300, and the corresponding door body 300 opens to the left and forward when opened. The rotation of the rotating member 12 can be rotation on a horizontal plane perpendicular to the vertical direction.

[0040] Thus, when installing the upper hinge, the door body connecting part 20 can be installed from top to bottom with the box body connecting part 10. The rotating part 12 is located above the fixed part 11. Therefore, the door body connecting part 20 first contacts the rotating part 12. During the downward installation of the door body connecting part 20, the downward pressing force is greater than the elastic force of the elastic member 13, which squeezes the rotating part 12 and drives it to rotate. The rotating part 12 rotates from the misaligned position to the aligned position, and then until the through hole 21 passes through the rotating part 12. Then the fixed boss 111 falls into the through hole 21. At this time, since the door body connecting part 20 no longer squeezes the rotating part 12, the rotating part 12 is reset under the action of the elastic member 13. The rotating part 12 rotates from the aligned position back to the misaligned position. Since the rotating part 12 returns to the misaligned position, the door body connecting part 20 is constrained by the rotating part 12 to the position that cooperates with the fixed boss 111. Therefore, at this time, the door body connecting part 20 and the box body connecting part 10 are relatively fixed. During the installation of the door connecting part 20, the rotatable characteristic of the rotating part 12 enables either the door connecting part 20 to be moved aside or the door connecting part 20 to be fixed in a position relative to the box connecting part 10, which simplifies the installation process of the hinge assembly 100 and achieves automatic alignment.

[0041] Therefore, this embodiment simplifies the installation process through the design of the fixing member 11, the rotating member 12 and the elastic member 13. It not only simplifies the installation steps of the hinge assembly 100, but also improves the reliability and stability of the hinge assembly 100 after installation, and prevents problems such as loosening or misalignment during use.

[0042] The cross-section of the through hole 21 is set as an irregular hole, and the cross-section of the fixing boss 111 matches the shape of the cross-section of the through hole 21. The irregular hole can be triangular, square, elliptical, waist-shaped, or a circle with several pieces cut off, that is, different from other shapes other than a circle. In this way, by matching the shape of the cross-section of the fixing boss 111 with the cross-section of the through hole 21, after the fixing boss 111 falls into the through hole 21, the position of the fixing boss 111 and the through hole 21 can always be relatively fixed, that is, the relative fixation of the door body connecting part 20 and the box body connecting part 10 is formed.

[0043] Furthermore, in the aligned position, the cross-section of the through hole 21 completely covers the cross-section of the rotating member 12. In the misaligned position, the cross-section of the through hole 21 at most covers a portion of the cross-section of the rotating member 12. That is, when the rotating member 12 is driven to rotate by the door connecting part 20, it can be covered by the through hole 21 of the door connecting part 20, and the rotating member 12 can completely pass through the through hole 21, or in other words, the door connecting part 20 passes through the rotating member 12 through the through hole 21. However, after the door connecting part 20 has passed through the rotating member 12, it returns to the misaligned position under the drive of the elastic member 13. Since the cross-section of the through hole 21 and the cross-section of the rotating member 12 are intersected, the through hole 21 can at most cover a portion of the rotating member 12, but cannot cover the entire cross-section of the rotating member 12. Therefore, the through hole 21 can only pass through the rotating member 12 from top to bottom, and cannot pass through the rotating member 12 from bottom to top.

[0044] By designing the cross-section of the through hole 21 as an irregular shape and matching the cross-section of the fixing boss 111 with that of the through hole 21, it is ensured that in the aligned position, the cross-section of the through hole 21 completely covers and passes through the cross-section of the rotating member 12. Similarly, due to the irregular hole design, in the misaligned position, the cross-section of the through hole 21 intersects with the cross-section of the rotating member 12, and the door connecting part 20 is fixed in a position limited by the box connecting part 10. This design improves the alignment accuracy of the hinge assembly 100, ensures the stability of the connecting parts, avoids loosening or misalignment caused by mismatched part shapes, and improves the overall quality and service life of the product.

[0045] The housing connection portion 10 also includes a first adjustment portion 14 and a second adjustment portion 15. The first adjustment portion 14 adjusts the movement of the fixing member 11 in a first direction T1, and the second adjustment portion 15 adjusts the movement of the fixing member 11 in a second direction T2. ​​On a plane perpendicular to the installation direction T0 of the door connection portion 20 toward the housing connection portion 10, the first direction T1 is perpendicular to the second direction T2. ​​The first adjustment portion 14 and the second adjustment portion 15 can be adjusted either mechanically or electrically. In this embodiment, the installation direction T0, the first direction T1, and the second direction T2 are as follows: Figure 2 , 6As shown in 7, 9 to 11, the installation direction T0 can be up and down, the first direction T1 can be parallel to the left and right direction, and the second direction T2 can be parallel to the front and back direction. In addition, the first direction T1 and the second direction T2 can also have an angle of inclination with the front, back, left and right directions.

[0046] The addition of a first adjustment part 14 and a second adjustment part 15, which are used to adjust the movement of the fixing member 11 in the first direction T1 and the second direction T2 respectively, gives the hinge assembly 100 a multi-directional adjustment capability. During installation, the position of the hinge can be finely adjusted as needed to ensure the optimal alignment of the door body 300 and the box body 200. This not only improves the flexibility of installation, but also adapts to different installation environments and requirements, thereby improving the efficiency of installation.

[0047] like Figure 7 and 8 As shown, the first adjusting part 14 includes a first adjusting bolt 142, a first tilting member 141, and a first positioning member. The first adjusting bolt 142 is rotatably connected to the first positioning member along the installation direction T0. The first adjusting bolt 142 and the first tilting member 141 are relatively fixed along the installation direction T0. The fixing member 11 includes a first tilting groove 112, and the first tilting member 141 is disposed in the first tilting groove 112. When the first adjusting bolt 142 moves along the installation direction T0, the first tilting member 141 abuts against the fixing member 11 and moves in the first direction T1. The fixing member 11 also includes a seat 114. A fixing boss 111 is provided on the top of the seat 114, and the first tilting groove 112 is provided on the left side of the seat 114. Through the cooperation of the first tilting member 141 and the first tilting groove 112, the vertical movement can be converted into horizontal movement, such as left-right movement.

[0048] When the first adjusting bolt 142 is rotated downwards (e.g., clockwise), it causes the first tilting member 141 to move downwards. The right side of the tilting member 141 presses down against the right side of the tilting groove 112, causing the seat 114 to move to the right. Conversely, when the first adjusting bolt 142 is rotated upwards (e.g., counterclockwise), it causes the first tilting member 141 to move upwards. The left side of the tilting member 141 presses down against the left side of the tilting groove 112, causing the seat 114 to move to the left. By rotating the first adjusting bolt 142 in different directions, the movement of the first tilting member 141 to the left or right can be controlled.

[0049] The rotation of the first adjusting bolt 142 drives the first tilting member 141 to move within the first tilting groove 112, thereby adjusting the position of the fixing member 11 and the door body connecting part 20 in the first direction T1. This design allows users to easily achieve precise positioning of the hinge by adjusting the bolt, improving the convenience and accuracy of installation and ensuring the smooth operation and alignment of the door body 300.

[0050] The second adjustment part 15 includes a second adjustment bolt 151, a second tilting member 152, and a second positioning member. The second adjustment bolt 151 is rotatably connected to the second positioning member along the installation direction T0. The second adjustment bolt 151 and the second tilting member 152 are fixed relative to each other along the installation direction T0. The fixing member 11 includes a second tilting groove 113. The second tilting member 152 is disposed in the second tilting groove 113. When the second adjustment bolt 151 moves along the installation direction T0, the second tilting member 152 abuts against the fixing member 11 and moves in the second direction T2.

[0051] Similar to the first adjusting part 14, the second adjusting bolt 151 of the second adjusting part 15 can also control the movement of the second inclined groove 113 and the door connecting part 20 in the second direction T2 by moving up and down. Taking the front-to-back direction as an example, when the second adjusting bolt 151 rotates downward (e.g., clockwise), it drives the second inclined member 152 to move downward. The inclined surface on the front side of the second inclined member 152 presses down against the inclined surface on the front side of the second inclined groove 113, causing the seat 114 to move forward. Conversely, when the second adjusting bolt 151 rotates upward (e.g., counterclockwise), it drives the second inclined member 152 to move upward. The inclined surface on the rear side of the second inclined member 152 presses down against the inclined surface on the rear side of the second inclined groove 113, causing the seat 114 to move backward. By rotating the second adjusting bolt 151 in different directions, the movement of the second inclined member 152 forward or backward can be controlled.

[0052] The rotation of the second adjusting bolt 151 causes the second tilting member 152 to move within the second tilting groove 113, thereby adjusting the position of the fixing member 11 and the door body connection 20 in the second direction T2. ​​This design provides more adjustment options, allowing the hinge assembly 100 to be precisely adjusted in the front-to-back direction, further enhancing the flexibility and adaptability of installation.

[0053] In this embodiment, the cross-section of the through hole 21 and the cross-section of the fixing boss 111 are both set to square, such as... Figure 7 and 8As shown, the fixed boss 111 includes two first sidewalls and two second sidewalls, which are arranged opposite to each other. The plane containing the first sidewalls is perpendicular to the first direction T1, and the plane containing the second sidewalls is perpendicular to the second direction T2. ​​That is, the two first sidewalls correspond to the first direction T1 adjusted by the first adjusting part 14. In other words, the first direction T1 is perpendicular to the first sidewalls, driving the left and right movement of the door connecting part 20 perpendicular to the first sidewalls, resulting in smoother movement and more even force distribution. Similarly, the driving in the front and back directions is also smoother. The second sidewalls are perpendicular to the second direction T2, ensuring that the driving force of the second adjusting part 15 on the door connecting part 20 in the front and back directions is also evenly distributed, allowing the door connecting part 20 to move smoothly.

[0054] The cross-sectional shape of the through hole 21 and the cross-sectional shape of the fixed boss 111 are designed to match the first direction T1 and the second direction T2, which ensures that the fixed boss 111 drives the door body connection part 20 smoothly and can be more accurately aligned in a uniform force distribution manner, thereby improving the installation accuracy and reliability of the hinge assembly 100.

[0055] In addition Figure 8 In this configuration, the first positioning member and the second positioning member can both be the same positioning member 16. A first positioning groove 161 and a second positioning groove 162 are provided on the positioning member 16. Both the first positioning groove 161 and the second positioning groove 162 are provided with threaded holes that match the first adjusting bolt 142 or the second adjusting bolt 151. The first tilting member 141 can move up and down in the first positioning groove 161, and the second tilting member 152 can move up and down in the second positioning groove 162. The positioning member 16 realizes the installation and fixation of the first adjusting part 14 and the second adjusting part 15.

[0056] like Figures 9-11 As shown, the door connecting part 20 also includes multiple adjustment holes 22. The first adjustment part 14 is aligned with one adjustment hole 22, and the second adjustment part 15 is aligned with another adjustment hole 22. The adjustment holes 22 are used to adjust the first adjustment part 14 and / or the second adjustment part 15 through the adjustment holes 22 from the outside of the box connecting part 10, so as to move the fixing member 11 in the first direction T1 and / or the second direction T2. ​​Specifically, the adjusting ends of the first adjusting bolt 142 and the second adjusting bolt 151 may both face the adjustment hole 22, and an external screwdriver may be used to rotate the first adjusting bolt 142 or the second adjusting bolt 151 through the adjustment hole 22.

[0057] The first adjustment part 14 and the second adjustment part 15 can be adjusted from the outside of the housing connection part 10 through these adjustment holes 22, realizing the movement of the fixing part 11 and the door connection part 20 in the first direction T1 and the second direction T2. ​​This design allows the user to easily make fine adjustments to the front, back, left and right sides of the door connection part 20 after installation, improving the convenience of installation and the flexibility of adjustment, ensuring the optimal alignment and stable connection between the door 300 and the housing 200, and guaranteeing the sealing of the housing 200.

[0058] Alternatively, holes corresponding to the adjustment holes 22 can be provided on the housing 201 for operating the first adjustment part 14 or the second adjustment part 15 through these holes.

[0059] like Figure 7 and 8 As shown, the rotating part 12 is a conical part. In the installation direction T0 from the door connecting part 20 to the box connecting part 10, the cross-sectional area of ​​the rotating part 12 gradually increases. The bottom surface of the rotating part 12 can be a plane. The edge that the rotating part 12 may contact with the door connecting part 20 is set as an arc-shaped edge, or a rounded corner structure. In this way, when the door connecting part 20 is inserted into the rotating part 12 from top to bottom, the contact with the rotating part 12 can smoothly drive it to rotate. When the door connecting part 20 moves below the rotating part 12, it can no longer drive the rotating part 12 to rotate because it is against the bottom surface of the rotating part 12.

[0060] In this embodiment, the elastic element 13 is set as a torsion spring. When the rotating element 12 is in the misaligned position, the torsion spring can also have a torsional deformation, thereby making the rotating element 12 better maintain in the misaligned position.

[0061] From the misaligned position to the aligned position, the rotating member 12 rotates 90°. When the fixed boss 111 is located in the through hole 21, the elastic member 13 drives the rotating member 12 back to the misaligned position.

[0062] like Figures 3-6 As shown, the fixing member 11 is at least partially fixed inside the housing 201, while the fixing boss 111 and the rotating member 12 protrude from the outside of the housing 201 through the opening 202. The cross-section of the opening 202 matches the cross-sectional shape of the fixing boss 111. This facilitates the installation and fixing of the hinge assembly 100, specifically the fixing of the housing connection part 10 to the housing 201, improving the stability and durability of the hinge assembly 100 and ensuring the reliability and stability of the refrigeration equipment during use.

[0063] During the production of the refrigeration equipment, the cabinet connecting part 10 is first installed from below the top shell 201, so that the rotating part 12 and the fixing part 11 protrude from the opening 202 above the top shell 201. The seat 114, the first adjusting part 14, and the second adjusting part 15 are located below the top shell 201. Then, the door connecting part 20 is fixed above the top shell 201. After the door 300 is installed, foam can be applied inside the cabinet 200. The foaming agent fixes the seat 114 inside the shell 201, thus completing the fixation of the hinge assembly 100.

[0064] Compared with commonly used technologies, this embodiment has the following advantages:

[0065] During installation, the improved hinge assembly 100 only requires pressing down the door connecting part 20 to drive the rotating part 12 from the misaligned position to the aligned position. Then, under the action of the elastic part 13, it automatically returns to the aligned position, thus completing the relative fixation between the door connecting part 20 and the box connecting part 10. This achieves the effect of automatic alignment and stable fixation. This design not only simplifies the installation steps and improves the installation efficiency, but also reduces the complexity of alignment adjustment. Furthermore, due to its good alignment effect, it can maintain the stable connection and reliable use of the door 300 during long-term use, improving the user experience.
