Thus, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein interpreted accordingly.

[0027] See also Figure 1-2 , which is a structural schematic diagram of a door body assembly 100 provided in one embodiment of the present invention.

[0028] The door body assembly 100 includes a door body 10, a door panel 20 covering the door body 10, and a connecting assembly 30 connecting the door body 10 and the door panel 20. The connecting assembly 30 can be used to adjust the position of the door panel 20 along the left-right direction, the up-down direction, and the front-back direction, so that the door panel 20 and the door body 10 are firmly fixed and the door body assembly 100 has a beautiful appearance.

[0029] The connecting assembly 30 includes at least a first adjusting mechanism 40 and a second adjusting mechanism 50; the first adjusting mechanism 40 is used to adjust the position of the door panel 20 along the left-right direction, and the second adjusting mechanism 50 is used to adjust the position of the door panel 20 along the up-down direction; wherein, the first adjusting mechanism 40 abuts against the second adjusting mechanism 50, and the second adjusting mechanism 50 has an abutting portion for the first adjusting mechanism 40 to abut so as to facilitate the left-right adjustment of the first adjusting mechanism 40, providing an abutting force for the first adjusting mechanism 40 to adjust along the left-right direction; the second adjusting mechanism 50 has a locking portion that cooperates with the first adjusting mechanism 40 to limit the up-and-down movement of the second adjusting mechanism 50, and the first adjusting mechanism 40 is relatively locked with the second adjusting mechanism 50 along the up-and-down direction.

[0030] In the prior art, the first adjustment mechanism 40 and the second adjustment mechanism 50 are mostly independently arranged to respectively realize the adjustment function of the two dimensions of the door panel 20. Figure 3-8 As shown, the first adjustment mechanism 40 abuts against the second adjustment mechanism 50 , which is used to assist in adjusting the door panel 20 along the left-right direction on the one hand, and can also assist in locking and limiting the door panel 20 on the other hand.

[0031] In a specific embodiment, the connecting assembly 30 includes a fixing bracket 31 installed on the door panel 20 and a connecting bracket 32 ​​arranged on the fixing bracket 31. The fixing bracket 31 includes a vertical wall 311 and a top wall 312 extending vertically from the vertical wall 311. The vertical wall 311 is attached to and fixed on the door panel 20. The movement of the fixing bracket 31 drives the door panel 20 to move synchronously. The connecting bracket 32 ​​includes end walls 321 located at both ends and a bottom wall 321 connected to the end walls 321.

[0032] Among them, the top wall 312 and the bottom wall 321 are installed in close contact and fixed to each other. In the above fixed state, the movement of the connecting frame 32 in the left and right direction will drive the fixed bracket 31 to move in the left and right direction, and the movement of the connecting frame 32 in the up and down direction will drive the fixed bracket 31 to move in the up and down direction.

[0033] Preferably, the connecting assembly 30 includes a first left adjustment mechanism 401 and a first right adjustment mechanism 402 disposed at both ends of the connecting assembly, and a pair of the second adjustment mechanisms 50 are disposed at both ends of the connecting frame 32 and cooperate with the first left adjustment mechanism 401 and the first right adjustment mechanism 402 respectively; specifically, the first adjustment mechanism 40 and the second adjustment mechanism 50 are disposed at both ends of the connecting frame 32. The first left adjustment mechanism 401 abuts against the corresponding second adjustment mechanism 50 to the right, and the first right adjustment mechanism 402 abuts against the corresponding second adjustment mechanism 50 to the left.

[0034] In this way, the first left adjustment mechanism 401 and the first right adjustment mechanism 402 are used to adjust the position of the door panel 20 to the left or right respectively, or when left-right adjustment is not needed, the second adjustment mechanism 50 is abutted to the left and right at the same time, so that the second adjustment mechanism 50 is clamped along the left-right direction, and the first adjustment mechanism 40 is also relatively locked to ensure that the position of the door panel 20 along the left-right direction is fixed.

[0035] In a specific embodiment, the second adjustment mechanism 50 is installed and matched with the door body 10 downward, and the door body 10 is fixed. The second adjustment mechanism 50 restricts the door body 10 from moving in the left-right direction, and only moves in the up-down direction to adjust the position of the door panel 20. Therefore, when the first adjustment mechanism 40 is relatively locked with the second adjustment mechanism 50 in the left-right direction, the door panel 20 is locked in the left-right direction.

[0036] The first adjustment mechanism 40 on each side can be subjected to the abutment force of the corresponding second adjustment mechanism 50 in the up-down direction, so that the first adjustment mechanism 40 is fixed relative to the second adjustment mechanism 50 in the up-down direction, and the second adjustment mechanism 50 can be locked and positioned in the up-down direction.

[0037] Combination Figure 5-8 As shown, when the first left adjustment mechanism 401 abuts the second adjustment mechanism 50 to the right, the abutting portion generates an abutting force in the opposite direction to the left, so that the connecting frame 32 moves to the left, or when the first right adjustment mechanism 402 abuts the second adjustment mechanism 50 to the left, the abutting portion generates an abutting force in the opposite direction to the right, so that the connecting frame 32 moves to the right. When the first left adjustment mechanism 401 and the first right adjustment mechanism 402 have been adjusted to the right and left in the left-right direction, the first left adjustment mechanism 401 and the first right adjustment mechanism 402 can simultaneously abut the second adjustment mechanism 50 to the right and left, so that the first adjustment mechanism 40 and the second adjustment mechanism 50 are locked in the left-right direction, and the door panel 20 cannot move in the left-right direction.

[0038] Preferably, the second adjusting mechanism 50 is provided with an annular groove 512, the groove surface of the annular groove 512 includes an inverted cone surface 5121, a circumferential surface 5122 and a right cone surface 5123, the circumferential surface 5122 connects the inverted cone surface 5121 and the right cone surface 5123, the first adjusting mechanism 40 abuts against the groove surface of the annular groove 512, at least the circumferential surface 5122 is formed as the abutting portion providing the abutting force in the left-right direction, and the inverted cone surface 5121 and the right cone surface 5123 are formed as the limiting portion providing the abutting force in the up-down direction.

[0039] The first adjustment mechanism 40 is provided with a cone 412 that abuts against the annular groove 512, and the cone 412 has an outer circumferential surface that adapts to the groove surface of the annular groove 512, and the outer circumferential surface includes a vertical plane 413 that cooperates with the circular surface 5122 and a side conical surface 414 that cooperates with the inverted conical surface 5121 and the right conical surface 5123.

[0040] In a specific embodiment, combined with Figure 7 As shown, the vertical plane 413 abuts against the circumferential surface 5122 in the left-right direction, thereby providing an abutting force that can be adjusted in the left-right direction. In practice, when the cone 412 abuts against the annular groove 512, the inverted conical surface 5121 and the right conical surface 5123 will also apply an abutting component force in the left-right direction to the side conical surface 414, so the groove surface of the annular groove 512 can be integrally formed as an abutting portion. The arc-shaped outer circumferential surface of the cone 412 just matches the arc-shaped groove surface of the annular groove 512, so that the cone 414 can rotate smoothly in the annular groove 512.

[0041] Each of the cones 412 can abut against the circumferential surface 5122 unidirectionally to the left or to the right, so that each of the cones 412 can be subjected to a rightward or leftward abutment force from the circumferential surface 5122 in the opposite direction; each of the cones 412 is located between the right conical surface 5123 and the inverted conical surface 5121, and the cone 412 abuts against the inverted conical surface 5121 upward, thereby being subjected to a downward force from the inverted conical surface 5121, and the cone 412 abuts against the right conical surface 5123 downward, thereby being subjected to an upward force from the right conical surface 5123.

[0042] In a specific embodiment, the second adjustment mechanism 50 includes a second adjustment member 51 and a second adjustment hole 53 arranged to cooperate with the second adjustment member 51, the second adjustment hole 53 is arranged on the bottom wall 321, and the second adjustment member 51 is arranged along the up and down directions and passes through the second adjustment hole 53; the second adjustment member 51 is a second screw, the second screw includes a second head 511 and a second threaded portion, the second head 511 is provided with the annular groove 512 and the annular nut 513, the annular groove 512 is arranged above the bottom wall 321, and the annular nut 513 is arranged below the bottom wall 321 to drive the bottom wall 321 to move upward.

[0043] Specifically, when adjusting the door panel 20 in the up and down directions, the second screw is adjusted. When the second screw makes a spiral motion upward, the annular nut 513 drives the bottom wall 321 to move upward, thereby driving the fixed bracket 31 to move upward. When the second screw makes a spiral motion downward, the connecting frame 32 automatically moves downward on the annular nut 513 due to gravity, thereby the fixed bracket 31 also moves downward.

[0044] At the same time, since the second screw is provided with an annular groove 512, when the second screw makes a spiral motion, the cone 412 rotates smoothly relative to the annular groove 512, and the groove surface of the annular groove 512 will not apply force to the cone 412 in the left and right directions. At the same time, the cone 412 is subjected to the abutment force of the positive conical surface 5123 and the inverted conical surface 5121 in the up and down directions, and moves up and down with the annular groove 512.

[0045] Preferably, a hexagonal groove 510 is provided on the top surface of the head of the second screw, and the hexagonal groove is not only used to tighten or loosen the second screw, but also can form a locking groove for cooperating with a locking column of a decorative cover 70 to lock, thereby limiting the displacement of the second screw in the up and down directions. When the position in the up and down directions is adjusted into place, the door panel 20 is locked in the correct position in the up and down directions.

[0046] In a specific embodiment, the first adjustment mechanism 40 includes a first adjustment member 41 and a first adjustment hole 43 arranged to cooperate with the first adjustment member 41, the first adjustment hole 43 is arranged on the end wall 322, and the first adjustment member 41 is arranged along the left-right direction and passes through the first adjustment hole 43; the first adjustment member 41 is a first screw, the first screw includes a first head 411 and a first threaded portion, and the tail of the first threaded portion is a cone 412; when the cone 412 abuts against the abutting portion to the left or right, it is subjected to an abutting force in the opposite direction of the abutting portion, thereby driving the connecting frame 32 to move to the right or left.

[0047] Specifically, when the door panel 20 needs to be adjusted to the left, the first screw of the first left adjustment mechanism 401 is adjusted, and the first screw is rotated to the right to abut the annular groove 512, and the cone 412 rotates in the annular groove 512. The cone 412 rotates smoothly between the positive conical surface 5123 and the inverted conical surface 5121 of the annular groove 512, and abuts against the groove surface of the annular groove 512 to the right. The first screw is threadedly engaged with the first adjustment hole 43, so that the connecting frame 32 moves to the left, thereby driving the door panel 20 to move to the left. At this time, the movement of the connecting frame 32 to the left will adaptively drive the first right adjustment mechanism 402 to move, thereby ensuring dynamic balance on both sides.

[0048] Specifically, when the adjusted first screw abuts against the second screw, it will not move in the left-right direction, but will only rotate, which is then converted into linear motion of the connecting frame 32 through threaded engagement.

[0049] Furthermore, the principle of adjusting the door panel 20 to the right is consistent with the above. When the door panel 20 has been adjusted to a suitable position along the left and right directions and no further adjustment is required, the first screw on the left side abuts against the annular groove 512 to the right, and the first screw on the right side abuts against the annular groove 512 to the left, thereby locking the position of the limit connecting frame 32 along the left and right directions and locking the door panel 20 in the correct position along the left and right directions.

[0050] In a specific embodiment, the first adjustment hole 43 is a circular threaded hole adapted to the first threaded portion, and the first threaded portion and the first adjustment hole 43 perform relative spiral motion to convert the rotational motion of the first screw into the linear motion of the connecting frame 32 .

[0051] The second adjustment hole 53 is an oblong hole. In the first adjustment state, the second adjustment member 51 moves in the left-right direction relative to the second adjustment hole 53. In the second adjustment state, the second adjustment member 51 drives the second adjustment hole 53 to move in the up-down direction. In other words, when adjusting in the left-right direction, because the connecting frame 32 needs to move in the left-right direction, the connecting frame 32 needs to provide a movement space for the second screw, otherwise the second screw and the connecting frame 32 are stuck, and the connecting frame 32 cannot move in the left-right direction; when adjusting in the up-down direction, the second screw is provided with a ring nut 513 below the second adjustment hole 53, which can drive the bottom wall 321 to move in the up-down direction.

[0052] Preferably, the connecting assembly 30 includes a third adjustment structure 60, and the third adjustment mechanism 60 is used to adjust the position of the door panel 20 along the front-to-back direction; the top wall 312 of the fixed bracket 31 is fastened to the connecting frame 32 through the third adjustment mechanism 60, so that when the connecting frame 32 moves, it can drive the fixed bracket 31 to move, thereby driving the door panel 20 to move.

[0053] The third adjustment mechanism 60 includes a third adjustment member 61 and a third adjustment hole 63 arranged to cooperate with the third adjustment member 61. The third adjustment hole 63 includes a long hole 631 arranged on the top wall 312 and a fixing hole 632 arranged on the bottom wall 321. The long hole 631 is aligned with the fixing hole 632 and is connected to the fixing hole.

[0054] Specifically, the elongated hole 631 is arranged along the front-to-back direction, and the third adjusting member 61 is a third screw, which is fixed to the fixing hole of the bottom wall 321. When the third screw is in a tightened state, the fixing bracket 31 and the connecting frame 32 are relatively fixed, and the movement of the connecting frame 32 can be used to drive the fixing bracket 31 to move. When the third screw is rotated and loosened, the third screw can move along the elongated hole 631 along the front-to-back direction to adjust the position of the fixing bracket 32 ​​and the connecting frame 32 along the front-to-back direction, thereby realizing the adjustment of the position of the door panel 20 along the front-to-back direction.

[0055] In a specific embodiment, the position of the door panel 20 in the front-to-back direction can be adjusted preferentially. When the door panel 20 is adjusted to the correct position along the front-to-back direction, the third screw is tightened to fix the fixing bracket 31 and the connecting frame 32. Secondly, the left-to-right direction can be adjusted. When the door panel 20 is in the correct position along the left-to-right direction, the position of the door panel 20 in the up-to-down direction is adjusted. When the second screw is adjusted along the up-to-down direction, it drives the first screw to move in the up-to-down direction without affecting the left-to-right displacement. After the door panel 20 is adjusted to the correct position along the up-to-down direction, the left and right first screws are pressed against the second screw, and the decorative cover 70 is installed. The locking column of the decorative cover 70 cooperates with the locking groove 510 of the second screw. At this time, the first screw, the second screw and the third screw are all in a completely locked state, and the locked door panel 20 is in the correct position.

[0056] In a specific embodiment, combined with Figure 3 As shown, the top wall 321 of the fixing bracket 32 ​​and the connecting frame 32 are located above the door body 10, and the door body assembly 100 includes the above-mentioned decorative cover 70 arranged above the first, second and third adjustment mechanisms. After the adjustment is completed, the decorative cover 70 is installed to cover the connecting assembly 30. If the position of the door panel 20 needs to be adjusted again later, the decorative cover 70 can be removed and adjusted directly. The other components of the connecting assembly 30 except the first, second and third adjustment mechanisms are preferably arranged between the door body 10 and the door panel 20.

[0057] The present case also protects a refrigeration device, more specifically a refrigerator, which includes a cabinet and a door assembly 100 as described in any of the above technical solutions, and the door assembly is used to open or close the cabinet.

[0058] The beneficial effects of the present invention are as follows: the first adjusting mechanism 40 abuts against the second adjusting mechanism 50, and the second adjusting mechanism 50 has an abutting portion for the first adjusting mechanism 40 to abut so as to facilitate left-right adjustment of the first adjusting mechanism 40; the second adjusting mechanism 50 has a limiting portion that cooperates with the first adjusting mechanism 40 to limit the up and down movement of the second adjusting mechanism 50, so that the first adjusting mechanism 40 is relatively locked with the second adjusting mechanism 50 along the up and down directions; the first adjusting mechanism 40 and the second adjusting mechanism 50 can respectively realize adjustment in two directional dimensions, and can also realize locking and limiting of the two.
