Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a door assembly and refrigeration equipment. Background Technology

[0002] In recent years, people have shown increasing preference for built-in home appliances. Especially for fully integrated products, where the appliance is completely embedded in the cabinet, users can choose the cabinet style to enhance the overall aesthetics and create a more cohesive look. Taking a fully integrated refrigerator as an example, the cabinet door is typically installed onto the refrigerator door. However, due to installation errors in the connection structure on the door or door panel, a gap exists between the door panel fixed to the refrigerator door and the cabinet door in the depth direction of the cabinet, affecting the appearance.

[0003] To address this issue, a connecting structure that allows for front-to-back adjustment of the door panel can be installed between the door body and the door panel. However, errors are unavoidable during production of the connecting structure on the door body and the connecting structure on the door panel, resulting in some minor wobbling space between the door body and the door panel after they are connected, causing the door panel to be uneven with the cabinet door panel. Summary of the Invention

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] The terms used in this document, such as “center,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” indicating spatial relative positions, are used 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 positions” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0041] For example, if the device in the figure is flipped, a unit described as being "below" or "under" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise), and the spatially related descriptive terms used herein will be interpreted accordingly.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] Furthermore, it should be understood that although the terms "first," "second," etc., may be used herein to describe various elements or structures, the objects being described should not be limited by these terms. These terms are only used to distinguish these objects from one another. For example, a first adjusting hole may be referred to as a second adjusting hole, and similarly, a second adjusting hole may be referred to as a first adjusting hole, without departing from the scope of protection of this application.

[0044] This application provides a door assembly that can be used in embedded refrigeration equipment, and the door assembly is connected to the housing 10 of the refrigeration equipment 100. In addition, it can also be used in other embedded home appliances.

[0045] like Figure 1 As shown, the aforementioned door assembly has a door body 1 and a decorative panel 2 disposed on the front side of the door body 1. A connecting component and an elastic component 7 are disposed between the door body 1 and the decorative panel 2. The connecting component includes a connecting structure and a mating part 5 that are connected to each other, one of which is disposed on the door body 1 and the other is disposed on the decorative panel 2. The elastic component 7 is disposed between the door body 1 and the decorative panel 2, providing a force that moves the door body 1 and the decorative panel 2 closer to or further away from each other.

[0046] The door body 1 and the decorative panel 2 are connected by a connecting structure and a fitting 5. The elastic component 7 provides a force that moves the door body 1 and the decorative panel 2 closer or further away from each other. When the decorative panel 2 still has a small space for movement in the front-back direction relative to the door body 1 after the connecting structure and fitting 5 are connected, the elastic component 7 pulls the decorative panel 2 closer to the door body 1 or pushes it away from the door body 1, so that the connecting structure and fitting 5 are always in contact, achieving the effect that the decorative panel 2 and the door body 1 are always fixed in the front-back direction.

[0047] In one embodiment of this application, as Figure 2 , 3 In the middle, the elastic component 7 includes a fixed shell 71, a pusher head 72 and elastic elements at both ends abutting or connected to the fixed shell 71 and the pusher head 72. The fixed shell 71 is fixed to one of the door body 1 and the decorative panel 2, and the pusher head 72 abuts against the other.

[0048] In the embodiments of this application, the fixing shell 71 is fixed to the side of the door body 1 facing the decorative panel 2, and the push head 72 abuts against the decorative panel 2 under the action of the elastic member, and pushes the decorative panel 2 away from the door body 1.

[0049] Of course, the fixing shell 71 can also be fixed to the decorative panel 2, and the pusher head 72 can be pressed against the door body 1, which can also push the decorative panel 2 away from the door body 1.

[0050] Alternatively, the two ends of the elastic element can be connected to the fixed shell 71 and the push head 72 respectively. In this case, the fixed shell 71 and the push head 72 need to be connected to the door body 1 or the decorative panel 2, instead of the push head 72 only abutting against the door body 1 or the decorative panel 2. The elastic element pulls the decorative panel 2 toward the door body 1.

[0051] In one embodiment of this application, the elastic component 7 further includes a guide cylinder 74 and a guide post 75. The guide post 75 is disposed inside the guide cylinder 74, and one of the two is fixed to the fixed shell 71, and the other is fixed to the push head 72. The elastic element is a spring 73, which is sleeved on the guide post 75 and the guide cylinder 74.

[0052] like Figure 3 In the middle, the guide cylinder 74 is fixed to the fixed shell 71, and the guide post 75 is fixed to the push head 72. With the cooperation of the guide cylinder 74 and the guide post 75, the movement direction of the push head 72 relative to the fixed shell 71 is restricted, so that the force provided by the spring 73 is always perpendicular to the door body 1 and the decorative panel 2, and the decorative panel 2 is prevented from being tilted relative to the door body 1.

[0053] In one embodiment of this application, the door body 1 includes a door shell 11 near the decorative panel 2. A fixed shell 71 is provided with a flange along its edge. The door shell 11 is provided with a through hole. The fixed shell 71 is aligned with the through hole and fixed to the side of the through hole away from the decorative panel 2. The flange covers the edge of the through hole.

[0054] The fixed shell 71 is opposite to the through hole on the door shell 11, so that the fixed shell 71 is exposed to the push head 72 through the through hole. The flange completely covers the through hole to prevent the foaming material in the heat insulation cavity from overflowing from the through hole.

[0055] In one embodiment of this application, the fixed shell 71 forms a cavity with an opening facing the pusher head 72. The inner wall of the cavity is provided with a limiting groove 711. The limiting groove 711 includes a limiting surface 7111 facing away from the opening of the fixed shell 71. The pusher head 72 is provided with a limiting buckle 721. The limiting buckle 721 has a guide surface 7211 and an abutment surface 7212. The pusher head 72 enters the fixed shell 71 under the guidance of the guide surface 7211, and the abutment surface 7212 and the limiting surface 7111 abut against each other.

[0056] The fixed shell 71 includes a square body with flanges extending outwards around the perimeter of the body. The square body forms a square cavity with an opening facing the decorative panel 2, and the pusher head 72, which is adapted to the square cavity, is also square.

[0057] When the pusher head 72 is installed on the fixed shell 71, the spring 73 is first put on the outside of the guide cylinder 74, and then the guide post 75 is aligned with the guide cylinder 74. Under the guidance and elastic force of the guide surface 7211, the limiting buckle 721 enters the limiting groove 711, and the abutting surface 7212 and the limiting surface 7111 abut against each other to prevent the fixed shell 71 and the pusher head 72 from separating from each other.

[0058] In one embodiment of this application, the connecting structure has a base 3, a connector 4 that can be displaced relative to the base 3 in the front-rear direction, a driving mechanism for driving the connector 4 to move, and a mating part 5 that is mated and connected to the connector 4.

[0059] The door body 1 and the decorative panel 2 are connected to the mating part 5 through the connector 4 in the connection structure. The connector 4 can move back and forth on the base 3 under the drive of the drive mechanism, so that the mating part 5 and the base 3 move relative to each other, and the decorative panel 2 and the door body 1 move relative to each other in the front and back direction. After the drive mechanism stops driving, the connector 4 remains stationary relative to the base 3, so that the decorative panel 2 can be adjusted to a suitable position in the front and back direction.

[0060] In one embodiment of this application, the base 3 is formed with a receiving cavity 31 that opens toward the mating member 5, and the connecting member 4 is disposed in the receiving cavity 31.

[0061] Thus, the mating part 5 extends into the receiving cavity 31 and connects with the connecting part 4, avoiding the connection position of the mating part 5 and the connecting part 4 between the door body 1 and the decorative panel 2, which would result in a large gap between the door body 1 and the decorative panel 2 that cannot be adjusted.

[0062] In one embodiment of this application, the connecting mechanism is disposed on the door body 1, and the mating part 5 is disposed on the decorative panel 2.

[0063] The door body 1 is relatively thick, which makes it easier to set up complex structures including the base 3 and the connector 4. Of course, the connecting structure can also be set on the decorative panel 2 and the mating part 5 can be set on the door body 1. This application takes the example of the connecting structure being set on the door body 1 and the mating part 5 being set on the decorative panel 2.

[0064] In one embodiment of this application, the door body 1 includes a door shell 11 with a heat insulation cavity, the door shell 11 is provided with an opening 1111 facing the decorative panel 2, and the base 3 is provided on the side of the opening 1111 away from the decorative panel 2.

[0065] The opening of the receiving cavity 31 formed by the base 3 is opposite to the opening 1111 on the door shell 11, and the base 3 is exposed towards the decorative panel 2 through the opening 1111 on the door shell 11. The base 3 extends with flanges around the opening of the receiving cavity 31 to ensure that the opening 1111 on the door shell 11 is completely covered. The base 3 can be sealed with tape or adhesive around the flanges to prevent foam material from overflowing from the opening 1111.

[0066] In one embodiment of this application, the base 3 is integrally formed and the side of it exposed to the insulation cavity is a closed design.

[0067] The base 3 is designed as a single piece, and the side of it exposed to the insulation cavity is a closed design. There is no need to worry about the base 3 needing to be spliced ​​at the location of the receiving cavity 31 due to molding issues, which would cause the foaming material to overflow into the receiving cavity 31.

[0068] In one embodiment of this application, as Figure 5 In the middle, the door shell 11 includes a front shell 111, a side shell 112 and an abutment shell 113 connected in sequence. The front shell 111 and the abutment shell 113 are located on the same side of the side shell 112. The sequential connection of the front shell 111, the side shell 112 and the abutment shell 113 makes the side cross-section of the door shell 11 U-shaped.

[0069] The base 3 includes a side portion 32. In the front-rear direction, the width of the side portion 32 matches the distance between the front shell 111 and the abutment shell 113, so that the base 3 is limited between the front shell 111 and the abutment shell 113 by the side portion 32, and the base 3 can be roughly limited by the U-shaped structure.

[0070] In one embodiment of this application, the door body 1 further includes a reinforcing member 12. The reinforcing member 12 includes a side reinforcing part 121 that abuts against the inner side of the side shell 112 and a rear reinforcing part 122 that abuts against the inner side of the abutting shell 113. The reinforcing member 12 has an L-shaped cross-section and is tightly attached to the inner side of the door shell 11. Here, the inner side refers to the side of the door shell 11 facing the insulation cavity.

[0071] Because the door shell 11 is relatively thin and has low strength, a reinforcing member 12 is provided on the side of the door shell 11 to enhance the strength of the side of the door shell 11 and the connection strength between the door shell 11 and the base 3 as described below. The reinforcing member 12 can be a reinforcing iron, and its thickness is greater than the thickness of the door shell 11.

[0072] In addition, at least two holes are provided at corresponding positions on the side shell 112, the side reinforcement 121 and the side edge 32 of the base 3, so that the base 3 can be fixed to the reinforcement 12 and the door shell 11 by fasteners such as screws through the side edge 32, and the two sets of holes can prevent the base 3 from rotating.

[0073] Regarding the connection method between the connector 4 and the mating part 5, this application provides the following Embodiment 1 and Embodiment 2: In embodiment 1, the connector 4 includes a side insert shaft 46 that spans the receiving cavity 31. The side insert shaft 46 has a connecting surface 461 that extends obliquely in the front-back direction. The mating member 5 is mated and connected with the connecting surface 461 and has a front-back movement under the action of the connecting surface 461.

[0074] The side insertion shaft 46 passes through the first adjustment hole 1121 on the side shell 112, the second adjustment hole 1212 on the side reinforcement 121 (at this time, the two adjustment holes are not necessarily elongated) and the connecting hole 33 on the base 3 and extends into the receiving cavity 31.

[0075] When the side insertion shaft 46 moves along its axial direction, that is, along the width direction of the door body 1, its connecting surface 461 also moves along the width direction. When the hook 51 is fixed in the width direction, the connecting surface 461 moves in the front-back direction, which will cause the hook 51 to move in the front-back direction, and at the same time drive the decorative panel 2 to move in the front-back direction.

[0076] In one embodiment of this example, as Figure 7 In the middle, the drive mechanism includes an adjusting rod 61, which is threadedly connected to the second adjusting hole 1212 on the side reinforcing part 121, and one end of the adjusting rod 61 abuts against the side insert shaft 46.

[0077] The connecting surface 461 is located on the side of the rear side of the side insert shaft 46, and its extension direction is: extending obliquely from front to back towards the side that abuts against the adjusting rod 61. When the adjusting rod 61 is rotated so that it moves toward one end of the side insert shaft 46, it pushes the side insert shaft 46 away from the side shell 112, thereby causing the connecting surface 461 to move relatively backward at the position of the hook 51, thereby driving the hook 51 to move backward.

[0078] In this embodiment, the base 3 has a guide groove 38 with an opening facing the adjusting rod 61 on the side of the connecting hole 33. The abutment also includes an abutment part 47, which is disposed at the end of the side insert shaft 46 that abuts against the adjusting rod 61. The abutment part 47 extends to the opening of the guide groove 38, and the abutment part 47 and the bottom end of the guide groove 38 away from the opening are abutted by an elastic element 471. The elastic element 471 can be a spring 73.

[0079] When the adjusting rod 61 rotates and moves toward the side insertion shaft 46, the elastic element 471 is compressed. When the adjusting rod 61 rotates and moves away from the side insertion shaft 46, the elastic element 471 causes the side insertion shaft 46 and the adjusting rod 61 to move in the same direction, the connecting surface 461 moves to the left, and relative to the hook 51, the connecting surface 461 moves forward.

[0080] At this point, the elastic component 7 mentioned above is needed to push the decorative panel 2 forward so that the hook 51 and the connecting surface 461 of the side insert shaft 46 are always in contact, and the hook 51 moves forward when the connecting surface 461 moves forward.

[0081] The mounting hardware is configured to include a side insert shaft 46 and also includes another embodiment as follows: like Figure 8In this embodiment, the difference from the previous embodiment is that the part of the side insert shaft 46 located in the connecting hole 33 is not circular. The adjusting rod 61 is threadedly connected to the side insert shaft 46, and the adjusting rod 61 is restricted from moving in the width direction. When the adjusting rod 61 rotates, the side insert shaft 46 moves towards or away from the side shell 112, that is, moves along the width direction, thereby driving the connecting surface 461 to move.

[0082] The end of the adjusting rod 61 near the side shell 112 is set as a head 611. The size of the head 611 is larger than the size of the second adjusting hole 1212. The adjusting rod 61 is provided with a locking groove on the side of the second adjusting hole 1212 away from the head 611. The second driving mechanism also includes a stop ring 62. The inner edge of the stop ring 62 is set in the locking groove, and the outer edge protrudes out of the locking groove.

[0083] The distance between the head 611 and the stop ring 62 is equal to the thickness of the side reinforcement 121, thereby limiting the movement of the adjusting rod 61 in the width direction. Of course, the distance between the head 611 and the stop ring 62 can also be slightly larger to avoid frequent friction between the head 611 and the stop ring 62.

[0084] In Example 2, as Figure 10 In the middle, the connector 4 forms a hook hole 411, and the mating part 5 extends from the hook hole 411 into the receiving cavity 31 to mate with the connector 4.

[0085] Connector 4 includes hook 51, such as Figure 11 The hook 51 is hung on the edge of the hanging hole 411; the mating part 5 also includes a fixing part 52 and a connecting part 53 that connects the hook 51 and the fixing part 52. In the front-back direction, the length of the connecting part 53 is equal to the thickness of the connecting part 4 at the position around the hanging hole 411.

[0086] The length of the connecting part 53 is equal to the distance between the hook 51 extending into the hanging hole 411 and the fixing part 52 fixed to the decorative panel 2. This distance is equal to the thickness of the connecting part 4 around the hanging hole 411, so that the mating part 5 and the connecting part 4 are fixed in the front-back direction after they are mated, thus preventing the decorative panel 2 from shaking in the front-back direction.

[0087] Of course, in actual production and use, the length of the connecting part 53 may have an error that is slightly greater than the thickness of the connecting part 4 around the hanging hole 411 (e.g., 0.1mm), in order to facilitate actual installation.

[0088] The base 3 includes a first inclined surface 3122 formed as the sidewall of the receiving cavity 31. The first inclined surface 3122 is inclined in the front-back direction. The connector 4 is provided with a second inclined surface 43 that cooperates with the first inclined surface 3122.

[0089] The driving mechanism includes an adjusting rod 61 connected to the connector 4. The adjusting rod 61 drives the connector 4 to move, so that the connector 4 has a forward and backward movement under the cooperation of the first inclined surface 3122 and the second inclined surface 43.

[0090] like Figure 11 In the middle, the first inclined surface 3122 and the second inclined surface 43 are inclinedly extended in the width direction of the door body 1.

[0091] The adjusting rod 61 drives the connecting piece 4 to move along the width direction of the door body 1, so that the connecting piece 4 has a displacement in the front and back direction under the cooperation of the first inclined surface 3122 and the second inclined surface 43, thereby driving the mating piece 5 to move in the front and back direction.

[0092] In one embodiment of this example, the base 3 is fixed to the end of the door shell 11 along the width direction of the door body 1, and is provided with a connecting hole 33 communicating with the receiving cavity 31; the connector 4 is provided with a travel groove 44 extending along the width direction of the door body 1, and the travel groove 44 is provided with a thread, the adjusting rod 61 passes through the connecting hole 33 and is threadedly connected to the connector 4, and drives the connector 4 to move through the thread.

[0093] The adjusting rod 61 passes sequentially from the side of the door body 1 through the first adjusting hole 1121 on the side shell 112, the second adjusting hole 1212 on the side reinforcement 121, and the connecting hole 33 on the base 3 before entering the stroke groove 44 and being threadedly connected to the thread in the stroke groove 44.

[0094] The end of the adjusting rod 61 located on one side of the door shell 11 is designated as a head 611. The head 611 is larger than the second adjusting hole 1212 but smaller than the first adjusting hole 1121. Thus, the head 611 can be positioned within the first adjusting hole 1121, avoiding protrusion from the side shell 112 and affecting aesthetics. Alternatively, the head 611 can be made larger than the first adjusting hole 1121, allowing it to protrude from the side shell 112.

[0095] The rotation of the adjusting rod 61 causes its head 611 to move closer to the connector 4. With the stop of the side reinforcement 121 and the head 611 of the adjusting rod 61, the head 611 of the adjusting rod 61 cannot actively move closer to the connector 4. Instead, the connector 4 moves towards the head 611 of the adjusting rod 61. Thus, with the cooperation of the first inclined surface 3122 and the second inclined surface 43, the connector 4 has the ability to move in the front and back direction.

[0096] like Figure 11 As shown, the first inclined surface 3122 and the second inclined surface 43 extend from front to back toward the head 611 of the adjusting rod 61. When the adjusting rod 61 rotates and drives the connecting piece 4 to move toward the head 611, the hook moves backward (decorative panel 2 → door body 1) at the same time, thereby driving the decorative panel 2 to move closer to the door body 1.

[0097] When the adjusting rod 61 rotates in the opposite direction, the head 611 of the adjusting rod 61 loses the obstruction of the side reinforcement 121 and moves away from the connector 4. Under the action of the aforementioned elastic component 7, the decorative panel 2 is pushed forward. With the cooperation of the first inclined surface 3122 and the second inclined surface 43, the connector 4 also moves away from the head 611 until the head 611 abuts against the side reinforcement 121 again.

[0098] Since the adjusting rod 61 moves together with the connecting piece 4, the first adjusting hole 1121 on the side shell 112, the second adjusting hole 1212 on the side reinforcing part 121, and the connecting hole 33 on the base 3 are all elongated holes extending in the front-back direction, and their length is greater than the outer diameter of the adjusting rod 61.

[0099] In this embodiment, the base 3 is provided with a guide rail 3123 at the top and / or bottom of the first inclined surface 3122, and the connector 4 is provided with a slide rail 431 at the position corresponding to the guide rail 3123. The slide rail 431 and the guide rail 3123 cooperate to make the second inclined surface 43 unable to separate from the first inclined surface 3122 in the width direction, that is, the second inclined surface 43 can only move in contact with the first inclined surface 3122.

[0100] Since the opening panel of the receiving cavity 31 of the base 3 is small, while the bottom area away from the decorative panel 2 is large, in this embodiment, the outer edge of the cross-sectional view of the connector 4 cut along the horizontal plane is a parallelogram, so that the connector 4 can be pushed into the receiving cavity 31 at an angle along the first inclined surface 3122.

[0101] In this embodiment, a locking groove is provided at the end of the adjusting rod 61 away from the head 611, and a stop ring 62 is provided in the locking groove. Since the stop ring 62 abuts against the end of the stroke groove 44, it prevents the adjusting rod 61 from disengaging from the stroke groove 44. Of course, if the adjusting rod 61 is long enough, the locking groove and the stop ring 62 may not be provided.

[0102] In the connection method of the connector 4 and the mating part 5 in this application, the following embodiments 3 and 4 are also included. In embodiments 3 and 4, the driving mechanism includes an adjusting rod 61 and a driving shaft 81, the connector 4 is a passive shaft 82, the driving shaft 81 and the passive shaft 82 are connected by a linkage shaft 83, the adjusting rod 61 is connected to the driving shaft 81 and drives the driving shaft 81 to move, and the driving shaft 81 drives the passive shaft 82 to move through the linkage shaft 83.

[0103] This implementation includes the following two examples: In one embodiment, for example, as shown below Figure 13 , 14In the embodiment 3 shown, the base 3 is provided with a first guide portion extending along the width direction of the door body 1 and a second guide portion extending in the front-back direction at the top and / or bottom of the receiving cavity 31. The drive shaft 81 cooperates with the first guide portion, and the passive shaft 82 cooperates with the second guide portion.

[0104] Under the restriction of the first guide section, the drive shaft 81 can only move along the first guide section in the width direction of the door body 1. Under the action of the linkage rod, the distance between the passive shaft 82 and the drive shaft 81 is fixed. Then the passive shaft 82 will be driven by the drive shaft 81 and move in the front-back direction under the action of the second guide section, thereby driving the mating parts 5 and the decorative panel 2 to move in the front-back direction.

[0105] The first guide portion and the second guide portion can be a groove or a hole. In one embodiment of this example, the base 3 is provided with a mounting groove 37 above and below the receiving cavity 31, a first guide hole 35 and a second guide hole 36 connecting the receiving cavity 31 and the mounting groove 37, and the first guide portion and the second guide portion are the first guide hole 35 and the second guide hole 36, respectively.

[0106] Both ends of the drive shaft 81 and the driven shaft 82 are connected by the linkage shaft 83, and a first guide hole 35 and a second guide hole 36 are provided at the top and bottom of the receiving cavity 31, so that the cooperation between the drive mechanism and the connecting piece 4 is more stable.

[0107] In one embodiment of this example, the drive mechanism further includes a first pin 84 and a second pin 85. The first pin 84 passes through the first guide hole 35 and is connected to the linkage shaft 83 and the drive shaft 81. The second pin 85 passes through the second guide hole 36 and is connected to the linkage shaft 83 and the driven shaft 82.

[0108] like Figure 13 In this configuration, one end of the first pin 84 and one end of the second pin 85 are respectively larger than the width of the first guide hole 35 and the second guide hole 36, and remain within the mounting groove 37. Alternatively, both the first pin 84 and the second pin 85 extend into the mounting grooves 37 provided at the top and bottom of the receiving cavity 31.

[0109] Of course, the drive shaft 81 can also be configured to consist of two sections, with the two opposite ends of the two sections passing through the first guide hole 35 respectively (when the first guide part and the second guide part are configured as grooves, the two ends of the drive shaft 81 extend into the grooves respectively) and move under the guidance of the first guide hole 35.

[0110] The passive shaft 82 can also be configured to consist of two sections, with the two opposite ends of the two sections passing through the second guide hole 36 respectively (when the first guide part and the second guide part are configured as grooves, the two ends of the active shaft 81 extend into the grooves respectively), and move under the guidance of the second guide hole 36.

[0111] Furthermore, the connection method between the drive shaft 81 / passive shaft 82 and the linkage shaft 83 is not limited to using a pin connection. The linkage shaft 83 can be fixed to the drive shaft 81 and the passive shaft 82 respectively to limit the distance between the drive shaft 81 and the passive shaft 82.

[0112] In one embodiment of this example, the adjusting rod 61 passes vertically through the drive shaft 81 and is threadedly connected to the drive shaft 81, and the adjusting rod 61 is fixed in the width direction of the door body 1.

[0113] When the adjustment rod 61 is restricted from moving in the width direction of the door body 1, the adjustment rod 61 can only rotate relative to the door body 1. When the adjustment rod 61 rotates, the drive shaft 81 will move to the left or right along the first guide hole 35 in the width direction of the door body 1 under the action of the thread. Thus, under the action of the linkage shaft 83, the passive shaft 82 will move along the second guide hole 36 in the front-back direction, thereby driving the mating part 5 and the decorative panel 2 to move in the front-back direction.

[0114] The base 3 is located at the end of the door body 1 in the width direction. The aforementioned side shell 112 is provided with a first adjustment hole 1121, and the side reinforcement 121 is provided with a second adjustment hole 1212 corresponding to the first adjustment hole 1121. The side part 32 of the base 3 is provided with a connection hole 33 communicating with the receiving cavity 31 corresponding to the first adjustment hole 1121 and the second adjustment hole 1212.

[0115] The adjusting rod 61 passes through the first adjusting hole 1121, the second adjusting hole 1212 and the connecting hole 33 from the side of the door body 1 and enters the receiving cavity 31, where it is threadedly connected to the drive shaft 81. The adjusting rod 61 extends at least partially out of the connecting hole 33, so that the user can rotate the adjusting rod 61 using the end of the adjusting rod 61.

[0116] In one embodiment of this example, a protrusion 34 is formed on the inner wall surface of the receiving cavity 31. The protrusion 34 is provided with a transverse groove 342 through which the adjusting rod 61 passes and a stop groove 341 located on one side of the transverse groove 342. The driving mechanism also includes a stop ring 62. The adjusting rod 61 is provided with a locking groove (not shown) surrounding the adjusting rod 61. The inner edge of the stop ring 62 is fixed in the locking groove, and the outer edge is limited to the stop groove 341.

[0117] Therefore, when the adjusting rod 61 rotates, it cannot move in the width direction due to the cooperation of the stop ring 62, the locking groove and the stop groove 341.

[0118] In one embodiment, for example, as shown below Figure 15 In the embodiment 4 shown, the linkage shaft includes a first linkage shaft 831 and a second linkage shaft 832 that are rotatably connected. The driving shaft 81 is rotatably connected to the first linkage shaft 831, and the passive shaft 82 is rotatably connected to both the first linkage shaft 831 and the second linkage shaft 832. The second linkage shaft 832 is rotatably connected to the base 3.

[0119] In this embodiment, the active shaft 81 and the passive shaft 82 are also connected by a linkage shaft. Under the action of the linkage shaft, the active shaft 81 drives the passive shaft 82 to move. The linkage shaft is divided into a first linkage shaft 831 and a second linkage shaft 832, and the two are connected to the active shaft 81 and the base 3 respectively at one end away from each other. The base 3 is fixed. When the active shaft 81 moves, it can drive the first linkage shaft 831 and the second linkage shaft 832 connected to the first linkage shaft 831, thereby driving the passive shaft 82 to move.

[0120] In one embodiment of this example, the base 3 is provided with a first guide portion extending along the width direction of the door body 1 at the top and / or bottom of the receiving cavity 31, and the drive shaft 81 cooperates with the first guide portion.

[0121] Under the restriction of the first guide section, the drive shaft 81 can only move along the first guide section in the width direction of the door body 1. Under the linkage of the first linkage shaft 831 and the second linkage shaft 832, the movement direction of the passive shaft 82 has a front-back component, thereby driving the mating part 5 and the decorative panel 2 to move in the front-back direction. The mating part 5 has a movable amount in the width direction after it is mated with the passive shaft 82.

[0122] Similar to the previous embodiments, the first guide portion can be a groove or a hole. In one embodiment of this embodiment, the base 3 is provided with a mounting groove 37 above and below the receiving cavity 31, and a first guide hole 35 connecting the receiving cavity 31 and the mounting groove 37. The first guide portion is the first guide hole 35.

[0123] Both ends of the drive shaft 81 and the driven shaft 82 are connected by a first linkage shaft 831 and a second linkage shaft 832, and a first guide hole 35 is provided at the top and bottom of the receiving cavity 31, so that the cooperation between the drive mechanism and the connecting piece 4 is more stable.

[0124] In one embodiment of this example, the drive mechanism further includes a first pin 84, a second pin 85, and a third pin 86. The first pin 84 passes through the first guide hole 35 and is connected to the linkage shaft 83 and the drive shaft 81. The second pin 85 connects the first linkage shaft 831, the second linkage shaft 832, and the driven shaft 82. The third pin 86 connects the second linkage shaft 832 and the base 3.

[0125] like Figure 15 In this configuration, one end of the first pin 84 is larger than the width of the first guide hole 35 and remains within the mounting groove 37. Alternatively, the first pin 84 extends into the mounting grooves 37 provided at the top and bottom of the receiving cavity 31.

[0126] A clearance notch is provided beside the first guide hole 35 to allow the second pin 85 to pass through the first linkage shaft 831, the second linkage shaft 832, and the driven shaft 82 from top to bottom or from bottom to top. A protrusion 39 is provided on the inner wall of the receiving cavity 31, and the protrusion 39 is provided with a fixing hole (not shown). The third pin 86 passes through the fixing hole and the second linkage shaft 832, so that the second linkage shaft 832 is rotatably connected to the base 3.

[0127] Of course, the drive shaft 81 can also be configured to consist of two sections, with the two opposite ends of each section passing through the first guide hole 35 (when the first guide part is configured as a groove, both ends of the drive shaft 81 extend into the groove respectively), and moving under the guidance of the first guide hole 35. Furthermore, the connection method between the driven shaft 82 and the first linkage shaft 831 and the second linkage shaft 832 is not limited to using a pin connection; the first linkage shaft 831 and the second linkage shaft 832 can be rotatably connected to the driven shaft 82.

[0128] In this embodiment, the drive mechanism also includes an adjusting rod 61, the function of which is the same as... Figure 13 The embodiments shown are the same, and will not be described again here.

[0129] In the two embodiments described above, the mating component 5 is as follows: Figure 13 , 15 The hook in the middle includes a locking ring 54 that forms an opening and a hinge 55 that opens or closes the opening.

[0130] The space in the front-to-back direction of the locking ring 54 is larger than the outer diameter of the passive shaft 82, so that when the decorative panel 2 is installed, the hinge 55 abuts against the passive shaft 82. After the decorative panel 2 is pushed from front to back, the passive shaft 82 enters the locking ring 54, and the hinge 55 can close automatically. However, since the front-to-back space of the locking ring 54 is larger than the outer diameter of the passive shaft 82, in both embodiments, the aforementioned elastic component 7 pushes the decorative panel 2 in a direction away from the door body 1, so that the passive shaft 82 always abuts against the hook.

[0131] Of course, the space in front and behind the locking ring 54 can also be set to be equal to the outer diameter of the passive shaft 82. In this case, a clearance groove is provided at the position where the hinge 55 rotates inward (inside the locking ring 54) and abuts against the inner side of the locking ring 54 to avoid the thickness of the hinge 55 occupying the space in front and behind the locking ring 54. After the passive shaft 82 enters the locking ring 54, the decorative panel 2 is moved along the width direction to close the hinge 55.

[0132] Alternatively, the drive mechanism and connecting member 4 of the two aforementioned embodiments can be rotated as a whole by 90°, that is, the passive shaft 82 is set horizontally, then the mating member 5 can be set to include Figure 11 The hook 51 is locked to the passive shaft 82 in the front-back direction after being attached to the passive shaft 82.

[0133] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0134] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
