Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a hinge assembly and a refrigeration device. Background Art

[0002] Embedded electrical appliances can be integrated with the external environment and are becoming more and more popular. Embedded refrigeration equipment, such as embedded refrigerators, generally includes a box body and a door body that rotates on the box body. A storage space is provided in the box body, and the door body is used to open or close the storage space. In order to make the door body more beautiful after closing, the distance between the embedded refrigeration equipment and the external environment is made as small as possible after the door body is closed, but such a structural setting will affect the opening of the door body. In order to solve the above technical problems, a hinge assembly with a dual-axis structure is used in the prior art, that is, while the door body rotates along the main axis during opening, there is also a secondary axis to guide the door body to control the movement of the door body, so that the movement of the door body can be controlled during the opening process to avoid interference from external environmental parts.

[0003] The hinge components in the prior art are mostly biaxial, with a relatively complex structure and complicated motion trajectory, which is not convenient for practical application. Summary of the invention

[0005] To achieve one of the above-mentioned objects, the present invention provides a refrigeration device comprising a box body, a door body and a hinge assembly; the door body is pivoted on the box body through the hinge assembly;

[0013] Furthermore, the bottom of the positioning groove also has a transition bottom connected between the first support bottom and the second support bottom. When the rotation control component moves into the avoidance cavity, the rotation control component slides relatively along the transition bottom from the first support bottom to the second support bottom and drives the moving rod to move.

[0040] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0041] One embodiment of the present invention provides a refrigeration device, which can be a box embedded in an external environment part. The external environment part can be, for example, a decorative part such as a cabinet or a stone slab. The refrigeration device can be a refrigerator or other household appliances embedded in the external environment part, such as a wine cabinet, a storage cabinet, etc.

[0042] In this embodiment, Figure 1 As shown, the refrigeration device includes a box body 1 for providing an internal storage space, a door body 2 and a hinge assembly 3, and the door body 2 is pivoted on the box body 1 through the hinge assembly 3 to open or close the storage space;

[0043] In this embodiment, the box body 1 has a box front wall 11 and a box side wall 12 arranged perpendicular to the box front wall 11. In this embodiment, the box front wall 11 and the box side wall 12 are roughly flat. The opening of the storage space is arranged on the box front wall 11, and the door body 2 is located at the front side of the box body 1 as a whole, and when the door body 2 is in a closed state, the opening of the storage space is closed. It should be noted that the front side here is the opening direction of the storage space.

[0044] The door body 2 also has a door front wall 21, a door side wall 22 and a door rear wall. The intersection of the door front wall 21 and the door side wall 22 forms a door outer edge 23, and the intersection of the door side wall 22 and the door rear wall forms a door inner edge 24. When the door body 2 is in a closed state, that is, when the door body 2 covers the storage space opening, the door front wall 21 is arranged on the side of the door body 2 away from the box front wall 11. In this embodiment, the door front wall 21 is flat as a whole, and is roughly parallel to the box front wall 11 when the door body 2 is in a closed state.

[0045] The box body 1 is arranged beside the external environment part. After the box body 1 is put in place, the box side wall 12 faces the first side of the external environment part, that is, the box side wall 12 is opposite to the first side of the external environment part, and the box side wall 12 is roughly parallel to the first side of the external environment part.

[0046] When the door body 2 is in the closed state, the door side wall 22 also faces the first side of the external environment component, and the door side wall 22 is opposite to the first side. In this embodiment, the door side wall 22 is flat as a whole, and is roughly parallel to the first side of the external environment component.

[0047] In this embodiment, the door front wall 21 and the door side wall 22 are both roughly planar. When the door body 2 is in a closed state, the door front wall 21 is parallel to the box front wall 11, and the plane where the door side wall 22 is located is parallel to the plane where the box side wall 12 is located. Of course, in other embodiments, the door front wall 21 and the door side wall 22 can also be curved or cambered.

[0048] In this specific embodiment, Figure 1-8 As shown, the hinge assembly 3 includes a hinge plate 31 and a rotating shaft 32; the hinge plate 31 is fixed on the box body 1 and has a rotating hole 310 and a protrusion 311 located on the inner wall of the rotating hole 310; the rotating shaft 32 is in the shape of a long column as a whole and is extended along its axial direction as a whole; the rotating shaft 32 has a rotating part 321 and a sliding part 322 arranged along the axial direction; the rotating part 321 is located in the rotating hole 310 and can rotate in the rotating hole 310; the door body 1 is provided with a sliding groove 25 that slidably cooperates with the sliding part 322;

[0049] The hinge assembly 3 further comprises a rotation control member 33 disposed on the rotating shaft 32, wherein the rotation control member 33 has a locking state in which the rotation control member 33 abuts against the protrusion 311 to limit the rotation of the rotating shaft 32;

[0050] Under the action of external force, the rotation control member 33 may shrink, deform or move to break away from the contact with the protrusion 311 , and the rotation portion 321 may rotate in the rotation hole 310 .

[0051] In this embodiment, the rotation control member 33 moves after being acted upon by an external force to avoid the protrusion 311 . After the rotation control member 33 and the protrusion 311 are no longer constrained on the rotation portion 321 , the rotation portion 321 can rotate in the rotation hole 310 .

[0052] In other embodiments, the rotation control member 33 may also generate elastic deformation and shrinkage after an external force acts to get rid of the restriction of the protrusion 311 .

[0053] In the initial stage of opening the door body 2, the sliding part 322 slides along the sliding groove 25. After sliding to the end of the sliding groove 25, as the force of pulling the door body 2 further increases, the force of pulling the door body 2 is transmitted to the rotating control member 33, forming an external force to control the movement of the rotating control member 33.

[0054] The rotation control member 33 contracts and deforms or moves after being acted upon by an external force, thereby releasing the locked state in which the rotation control member 33 abuts against the protrusion 311. In the locked state, the rotation control member 33 abuts against the protrusion 311, thereby limiting the rotation of the rotation portion 321 in the rotation hole 310. After the rotation control member 33 is freed from the limitation of the protrusion 311, the rotation portion 321 can rotate in the rotation hole 310.

[0055] In this embodiment, by providing a sliding portion 322 and a rotating portion 321 in the axial direction of the rotating shaft 32, the door body 2 adopts different methods at different stages during the opening process. The rotating shaft of the door body 2 first slides and then rotates in situ, so that the door body 2 can better avoid interference from other components in the initial stage of opening. After the door body 2 is opened to a certain angle, the rotating shaft 32 can rotate through the rotating portion 321 to achieve a larger angle of opening of the door body.

[0056] like Figure 4-11 As shown, the hinge assembly 3 also has a reset mechanism 4; an avoidance cavity 3210 is provided in the rotating portion 321, and under the action of an external force, the rotating control member 33 moves toward the avoidance cavity 3210;

[0057] After the external force is removed, the reset mechanism drives the rotation control member 33 to reset and move toward the outside of the avoidance cavity 3210 .

[0058] The reset mechanism can better realize the reset of the rotary control member 33 when the door body 2 is closed, so that it can be used again when the door is opened next time.

[0059] In a specific embodiment, the reset mechanism includes a reset spring 341 and a moving rod 342 matched with the reset spring 341, the moving rod 342 is provided with a positioning groove 343 adapted to the rotation control member 33, and the bottom of the positioning groove 343 is provided with a first supporting bottom 3431 and a second supporting bottom 3432; the first supporting bottom 3431 is located closer to the opening position of the avoidance cavity 3210 relative to the second supporting bottom 3432;

[0060] like Fig.13 As shown, under the action of external force, the rotation control member 33 moves toward the avoidance cavity 3210, and the moving rod 342 moves to change the rotation control member 33 from abutting against the first support bottom 3431 to abutting against the second support bottom 3432; Fig.12 As shown, after the external force is removed, the return spring 341 drives the moving rod 342 to return and move and pushes the rotating control member 33 to move out of the avoidance cavity 3210 .

[0061] It should be noted that under the action of external force, the rotating control member 33 only produces a tendency to move toward the avoidance chamber 3210 and does not need to be completely contained in the avoidance chamber 3210. The avoidance chamber 3210 is arranged in the rotating part 321 and has an opening arranged on the outer wall of the rotating part 321. The rotating control member 33 protrudes outward from the opening.

[0062] In other embodiments, the rotation control member 33 may be directly disposed on the outer wall of the rotating portion 321 . In this case, the rotation control member 33 may be configured as an elastically deformable member.

[0063] like Figure 9-11 As shown, the rotation control member 33 is respectively pressed against two support seats, and the positions of the two support seats are different. The first support seat 3431 is located closer to the opening of the avoidance cavity 3210 relative to the second support seat 3432. Therefore, when the rotation control member 33 is pressed against the first support seat 3431, the rotation control member 33 extends out of the avoidance cavity 3210 to a greater extent, thereby achieving a press against the protrusion 311 to limit the rotation of the rotating part 321 in the rotating hole 310. When the rotation control member 33 is pressed against the second support seat 3431, the rotation control member 33 moves in the avoidance cavity 3210 to avoid the protrusion 311, and gets rid of the restriction of the protrusion 311, so that the rotating part 321 can rotate in the rotating hole 310.

[0064] In other embodiments, the resetting movement of the rotation control member 33 can be controlled only by the resetting member. Specifically, the resetting member can be set in the rotation control member 33 and the avoidance cavity 3210, and the resetting member can be telescopically deformed along the moving direction of the rotation control member 33.

[0065] The movement of the moving rod 342 can be controlled by an independent control mechanism, or can be linked with the rotation control member 33 . In this embodiment, the rotation control member 33 controls the movement of the moving rod 342 .

[0066] Specifically, Figure 9-11 As shown, the bottom of the positioning groove 343 also has a transition bottom 3433 connected between the first support bottom 3431 and the second support bottom 3432. When the rotation control member 33 moves toward the avoidance cavity 3210, the rotation control member 33 slides relatively along the transition bottom 3433 from the first support bottom 3431 to the second support bottom 3432, and drives the moving rod 342 to move.

[0067] The transition bottom 3433 is tilted as a whole and connected between the first support bottom 3431 and the second support bottom 3432 . The setting of the transition bottom 3433 enables the rotation control member 33 to move smoothly between the first support bottom 3431 and the second support bottom 3432 , thereby driving the moving rod 342 to move.

[0068] In this embodiment, the moving rod 342 can move along the axial direction of the rotating shaft 32 , the first supporting base 3431 is relatively arranged on the upper side of the second supporting base 3432 , and one end of the return spring 341 is fixed to the bottom of the moving rod 342 .

[0069] The moving rod 342 is configured to move in the vertical direction, so that after the external force is removed, the moving rod 342 can be reset downward under the action of its own gravity, thereby better realizing the reset of the moving rod 342. Under the combined action of the gravity of the moving rod 342 and the reset spring 341, the rotating control member 33 extends out of the avoidance cavity 3210 and presses against the protrusion 311.

[0070] Furthermore, when the rotation control member 33 is pressed against the second support bottom 3432 , the top of the moving rod 342 protrudes upward from the top of the sliding portion 322 , and the top of the moving rod 342 is pressed against the bottom of the sliding groove 25 .

[0071] The moving rod 342 moves upward, thereby forming an avoidance for the movement of the rotation control member 33 into the avoidance cavity 3210, so as to realize the rotation of the rotating part 321 in the rotating hole 310. In this embodiment, the top of the moving rod 342 protrudes upward from the top of the sliding part 322 and abuts against the bottom of the sliding groove 25, which can realize stable support of the rotating shaft 32 during the rotation process.

[0072] In a specific embodiment, Figure 12-13 As shown, the protrusion 311 has a rotation limit surface 3111 and a guide surface 3112 arranged opposite to each other, and the rotation control member 33 has a rotation abutment surface 331 and a reset guide surface 332 arranged opposite to each other; the rotation abutment surface 331 abuts against the rotation limit surface 3111 to limit the rotation of the rotation control member 33 in the rotation hole 310; the reset guide surface 332 can be reset and moved along the guide surface 3112.

[0073] During the opening of the door 2, Fig.12 As shown, in the initial stage, the rotation abutment surface 331 abuts against the rotation limit surface 3111 to limit the rotation of the rotation part 321 in the rotation hole 310. At this time, the rotation shaft 32 can only make the sliding part 322 slide along the slide groove 25 of the door body 2. When sliding along the slide groove 25 to the end of the slide groove 25, as the door body 2 is further opened, the force acting on the rotation control member 33 increases to overcome the force of the reset mechanism 34, and the rotation control member 33 moves inward and moves toward the avoidance cavity 3210. Fig.13 As shown, the rotation control member 33 can cross the protrusion 311 and move from the rotation limit surface 3111 to the guide surface 3112. The rotation control member 33 is freed from the restriction of the protrusion 311 and can rotate in the rotation hole 310, thereby increasing the opening angle of the door body 2.

[0074] When the door body 2 is closed, the return guide surface 332 of the rotation control member 33 passes over the protrusion 311 along the guide surface 3112 , so that the rotation control member 33 moves to the rotation abutment surface 331 and abuts against the rotation limit surface 3111 .

[0075] In this embodiment, the rotation limiting surface 3111 and the guide surface 3112 form the inner wall of the rotation hole 310, and the inner wall of the rotation hole 310 also has a curved surface 3101. The rotating part 321 has a pair of rotating shaft curved surfaces 3211 arranged opposite to each other, and the arc length of the curved surface 3101 is greater than the arc length of the rotating shaft curved surface 3211.

[0076] The arc surface 3211 of the rotating shaft is opposite to the arc surface 3101 , and the arc length of the arc surface 3102 is greater than the arc length of the arc surface 3211 of the rotating shaft, so that the rotating shaft 32 has a larger rotation space in the rotating hole 310 , thereby better realizing the rotation of the rotating shaft 32 .

[0077] It should be noted that, in order to better control the rotation of the rotating portion 321 , a pair of protrusions 311 are provided on the inner wall of the rotating hole 310 , and the pair of protrusions 311 are centrally symmetrically arranged with the rotating hole 310 as the center.

[0078] Correspondingly, two rotation control members 33 are also provided, and the positioning grooves 343 are respectively provided on opposite sides of the moving rod 342 . The pair of rotation control members 33 are centrally symmetrically arranged with the moving rod 342 as the center.

[0079] like Figure 12-13 As shown, in this embodiment, a sliding portion rotation limiting surface 3221 is provided on the sliding portion 322 , and the sliding portion rotation limiting surface 3221 is used to abut against the inner wall of the sliding groove 25 to limit the sliding portion 322 from rotating in the sliding groove 25 .

[0080] The sliding portion rotation limiting surfaces 3221 are arranged opposite to each other on two sides of the sliding portion 321 so that the sliding portion 321 is flat as a whole. The flat sliding portion 321 can only slide in the sliding groove 25 but cannot rotate.

[0081] In the initial stage of opening the door body 2, in order to avoid interference between the inner edge 24 of the door and the box body 1, and also to avoid interference between the outer edge 23 of the door and the external environment, the door body 2 moves in a direction away from the box body 1 and the external environment at the same time, that is, the door body 2 moves in a direction away from the front wall 11 and the side wall 12 of the box at the same time.

[0082] Correspondingly, the slide groove 25 is extended in a curved shape as a whole, and when the door body 2 is closed, the slide groove 25 is extended in a direction gradually approaching the door side wall 22 and gradually away from the door front wall 21 .

[0083] It can be understood that the refrigeration device can be a refrigerator, and a built-in refrigerator.

[0084] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
