Description

Technical Field

[0001] This invention relates to the field of door opening mechanism technology, and in particular to a hinge assembly and a housing device. Background Technology

[0002] For enclosure devices with doors and enclosures, when the door is opened relative to the enclosure, it may extend beyond the outer wall of the enclosure device. This can cause interference between the door and the installation environment of the enclosure device. For example, in the case of recessed installation of the enclosure device, the portion of the door extending beyond the outer wall of the enclosure device may interfere with the embedded wall. Summary of the Invention

[0003] In view of this, the main technical problem solved by the present invention is to provide a hinge assembly and a housing device that can reduce the risk of interference and collision during door rotation.

[0004] To solve the above-mentioned technical problems, the present invention provides a box-shaped device. The box-shaped device includes a box body with an internal accommodating space having an opening. The box body also has a pivot side and a target side, which are arranged opposite to each other on either side of the opening. The box-shaped device further includes a door for sealing the opening. The box-shaped device also includes a hinge assembly located on the pivot side. The hinge assembly includes a first support member and a second support member, the first support member being located in the box body and the second support member being located in the door body. The hinge assembly also includes a first swing arm and a second swing rod, the first swing rod having a first pivot portion and a second pivot portion, the first swing rod being pivoted via a first pivot. The first pivot is rotatably connected to the first support member and rotatably connected to the second support member through the second pivot member. The second pivot has a third pivot and a fourth pivot. The second pivot is rotatably connected to the first support member through the third pivot and rotatably connected to the second support member through the fourth pivot. When the door is blocked in the opening, the first pivot and the third pivot are away from the box relative to the second pivot and the fourth pivot. The relative directions of the first pivot and the second pivot are inclined relative to the relative directions of the third pivot and the fourth pivot, which is used to guide the door to rotate away from the box and to guide the door to move towards the target side.

[0005] In one embodiment of the present invention, the distance between the first pivot and the third pivot is less than the distance between the second pivot and the fourth pivot.

[0006] In one embodiment of the present invention, when the door is blocked at the opening, the first swing arm moves closer to the target side relative to the second swing arm; during the process of the door rotating relative to the box from the state of blocking the opening, the distance that the fourth pivot moves toward the box is less than the distance that the second pivot moves away from the box.

[0007] In one embodiment of the present invention, when the door is blocked in the opening, the second pivot portion is closer to the target side relative to the first pivot portion.

[0008] In one embodiment of the present invention, the distance between the first pivot and the second pivot is greater than the distance between the third pivot and the fourth pivot.

[0009] In one embodiment of the present invention, when the door is blocked in the opening, the first swing arm is closer to the target side relative to the second swing arm; the hinge assembly also includes a stop member; the stop member is disposed on the first support member and / or the second support member, and the stop member limits the maximum opening angle of the door by abutting against the second swing arm.

[0010] In one embodiment of the present invention, when the door is blocked in the opening, the fourth pivot portion moves away from the target side relative to the third pivot portion.

[0011] In one embodiment of the present invention, when the door thickness is 50mm, the distance between the first pivot and the third pivot is 20±1mm, the distance between the first pivot and the second pivot is 27.2±1mm, the distance between the second pivot and the fourth pivot is 40±2mm, and the distance between the third pivot and the fourth pivot is 20.4±1mm; when the door thickness is 60mm, the distance between the first pivot and the third pivot is 24.5±1mm, and the distance between the first pivot and the second pivot is... The distance between the first and second pivots is 36.4±1mm, the distance between the second and fourth pivots is 50±2mm, and the distance between the third and fourth pivots is 29.7±1mm; when the thickness of the door body is 77mm, the distance between the first and third pivots is 28±1mm, the distance between the first and second pivots is 41.2±1mm, the distance between the second and fourth pivots is 59±2mm, and the distance between the third and fourth pivots is 36.9±1mm.

[0012] In one embodiment of the present invention, the first to fourth pivot parts are all rod structures; the first pivot part and the third pivot part are rotatably embedded in the pivot hole on the first support member, and the second pivot part and the fourth pivot part are rotatably embedded in the pivot hole on the second support member.

[0013] In one embodiment of the present invention, one of the second support member and the door body is provided with a connecting shaft, and the other is provided with a connecting hole. The connecting shaft is embedded in the connecting hole to fix the second support member to the door body.

[0014] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is to provide a hinge assembly. The hinge assembly has a first side and a second side disposed opposite to each other along a first direction, and a third side and a fourth side disposed opposite to each other along a second direction, wherein the first direction is perpendicular to the second direction. The hinge assembly includes a first support member and a second support member. The hinge assembly further includes a first pivot rod, which has a first pivot portion and a second pivot portion. The first pivot rod is rotatably connected to the first support member through the first pivot portion and rotatably connected to the second support member through the second pivot portion. The hinge assembly further includes a second pivot rod, which has a third pivot portion and a fourth pivot portion. The second pivot rod is rotatably connected to the first support member through the third pivot portion and rotatably connected to the second support member through the fourth pivot portion. When the hinge assembly is in its initial state, the first pivot portion and the third pivot portion are closer to the first side relative to the second pivot portion and the fourth pivot portion in the first direction, and the relative directions of the first pivot portion and the second pivot portion are inclined relative to the relative directions of the third pivot portion and the fourth pivot portion, for guiding the second carrier member to rotate relative to the first carrier member and guiding the second carrier member to move towards the fourth side in the second direction.

[0015] The beneficial effects of this invention are as follows: Unlike the prior art, this invention provides a hinge assembly and a housing device. The hinge assembly of the housing device of this invention includes a first pivot rod and a second pivot rod. When the door is blocked in the opening, the first pivot portion of the first pivot rod and the third pivot portion of the second pivot rod are away from the housing relative to the second pivot portion of the first pivot rod and the fourth pivot portion of the second pivot rod. The relative directions of the first pivot portion and the second pivot portion are inclined relative to the relative directions of the third pivot portion and the fourth pivot portion, which is used to guide the door to rotate away from the housing and guide the door to move towards the target side, thereby reducing the degree to which the door extends beyond the outer wall of the housing and reducing the risk of the door interfering with or colliding with the external structure during rotation.

[0031] To address the technical problem of interference and collision easily occurring during door rotation in existing technologies, an embodiment of the present invention provides a box-type device. The box-type device includes a box with an internal accommodating space having an opening. The box also has a pivot side and a target side, which are arranged opposite to each other on either side of the opening. The box-type device further includes a door for sealing the opening. The box-type device also includes a hinge assembly located on the pivot side. The hinge assembly includes a first support member and a second support member, with the first support member located in the box and the second support member located in the door. The hinge assembly also includes a first swing arm and a second swing rod, the first swing arm having a first pivot portion and a second pivot portion, the first swing arm being pivoted via a first pivot. The first pivot member is rotatably connected to the first support member and rotatably connected to the second support member via a second pivot member. The second pivot member has a third pivot member and a fourth pivot member. The second pivot member is rotatably connected to the first support member via the third pivot member and rotatably connected to the second support member via the fourth pivot member. When the door is blocked in the opening, the first pivot member and the third pivot member are moved away from the housing relative to the second pivot member and the fourth pivot member. The relative directions of the first pivot member and the second pivot member are inclined relative to the relative directions of the third pivot member and the fourth pivot member, which is used to guide the door to rotate away from the housing and to guide the door to move towards the target side. This will be described in detail below.

[0032] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of an embodiment of a prior art refrigeration device.

[0033] In the prior art, the hinge structure used for opening and closing the door of refrigeration equipment such as refrigerators typically adopts a single hinge shaft design. For example, the refrigerator body 11 is provided with a hinge fixing plate 12, and a hinge shaft 13 is provided on the hinge fixing plate 12. The door body 14 of the refrigerator 10 is provided with a shaft hole (not shown in the figure), and the hinge shaft 13 is inserted into the shaft hole. The hinge shaft 13 can rotate in the shaft hole, so that the door body 14 can rotate relative to the body 11, thereby realizing the opening and closing of the door body 14.

[0034] As home decoration styles gradually trend towards integration, concealment, and simplicity, the built-in installation of refrigerator 10 has emerged accordingly, such as embedding refrigerator 10 into cabinet 15. However, due to the limitation of the existing hinge structure using a single hinge axis design, the door 14 may extend beyond the outer wall 111 of the cabinet 11 during rotation relative to the cabinet body 11. This leads to the potential for interference or collision between the door 14 and external structures (such as cabinet 15) during rotation.

[0035] In view of this, embodiments of the present invention provide a housing device that can reduce the extent to which the door extends beyond the outer wall of the housing during rotation, as described in detail below.

[0036] Please see Figure 2 , Figure 2 This is a top view of an embodiment of the housing device of the present invention.

[0037] In one embodiment, the cabinet device can be a refrigeration device such as a refrigerator or freezer. Of course, the cabinet device can also be other devices having a cabinet 20 and a door 30, and requiring the door 30 to be able to rotate relative to the cabinet 20. The following description uses a refrigerator as an example of the cabinet device only for illustrative purposes and does not limit the specific form of the cabinet device.

[0038] The enclosure device includes an enclosure 20. The enclosure 20 is the storage medium of the enclosure device, in which users store items that need to be refrigerated or frozen. Specifically, the enclosure 20 has an internal receiving space 21 with an opening 22 through which items that need to be refrigerated or frozen are stored.

[0039] The enclosure also includes a door 30, which is used to seal the opening 22 of the receiving space 21. When the door 30 seals the opening 22, i.e., the door 30 is in the closed state, a relatively enclosed space is formed inside the enclosure 20 for storing items. The door 30 is rotatably connected to the pivot side 23 of the enclosure 20, meaning the door 30 can rotate relative to the enclosure 20. The enclosure 20 also has a target side 24, with the pivot side 23 and the target side 24 positioned opposite each other on either side of the opening 22. The pivot side 23 and the target side 24 are aligned along a second direction (e.g., Figure 2 (As indicated by the middle arrow X, the same below) are set relative to each other, wherein the second direction is parallel to the plane where the opening 22 is located (e.g., Figure 2 As shown in the midplane α (the same applies below).

[0040] In one embodiment, the housing assembly further includes a hinge assembly 40. The hinge assembly 40 is located on the pivot side 23 of the housing 20 and pivotally connects the housing 20 and the door 30, thus achieving a rotatable connection between the housing 20 and the door 30. Specifically, the hinge assembly 40 includes a first support member 41 and a second support member 42, with the first support member 41 located on the housing 20 and the second support member 42 located on the door 30.

[0041] It should be noted that the first load-bearing member 41 can be an integral part of the housing 20, meaning the first load-bearing member 41 can be a component of the housing 20. Alternatively, the first load-bearing member 41 can be independent of the housing 20. Similarly, the second load-bearing member 42 can be an integral part of the door 30, meaning the second load-bearing member 42 can be a component of the door 30. Alternatively, the second load-bearing member 42 can be independent of the door 30.

[0042] Please refer to the following: Figure 3 and Figure 4 The hinge assembly 40 has a first direction (e.g., Figure 3 (As indicated by the middle arrow Y, the same below) The first side Y1 and the second side Y2 are arranged opposite to each other, and the third side X1 and the fourth side X2 are arranged opposite to each other along the second direction, wherein the first direction is perpendicular to the second direction.

[0043] The hinge assembly 40 also includes a first pivot arm 43. The first pivot arm 43 has a first pivot portion 431 and a second pivot portion 432. The first pivot arm 43 is rotatably connected to the first support member 41 via the first pivot portion 431, and is also rotatably connected to the second support member 42 via the second pivot portion 432. The hinge assembly 40 also includes a second pivot arm 44. The second pivot arm 44 has a third pivot portion 441 and a fourth pivot portion 442. The second pivot arm 44 is rotatably connected to the first support member 41 via the third pivot portion 441, and is also rotatably connected to the second support member 42 via the fourth pivot portion 442.

[0044] When the hinge assembly 40 is in its initial state, the first pivot portion 431 and the third pivot portion 441 are close to the first side Y1 relative to the second pivot portion 432 and the fourth pivot portion 442 in the first direction, and the relative direction of the first pivot portion 431 and the second pivot portion 432 is inclined relative to the relative direction of the third pivot portion 441 and the fourth pivot portion 442, for guiding the second support member 42 to rotate relative to the first support member 41 and guiding the second support member 42 to move towards the fourth side X2 in the second direction.

[0045] In this embodiment, when the hinge assembly 40 is applied to the aforementioned housing device, the initial state of the hinge assembly 40 refers to the door 30 being sealed at the opening 22. When the door 30 is sealed at the opening 22, the first pivot portion 431 and the third pivot portion 441 are away from the housing 20 relative to the second pivot portion 432 and the fourth pivot portion 442. In other words, the first pivot portion 431 is away from the housing 20 relative to the second pivot portion 432 and the fourth pivot portion 442, and the third pivot portion 441 is also away from the housing 20 relative to the second pivot portion 432 and the fourth pivot portion 442. The relative directions of the first pivot portion 431 and the second pivot portion 432 are inclined relative to the relative directions of the third pivot portion 441 and the fourth pivot portion 442, so that the door 30 is guided to rotate relative to the housing 20 during the opening process of the door 30 from the state of sealing the opening 22.

[0046] Furthermore, the swinging of the first swing arm 43 and the second swing arm 44 guides the door 30 to move towards the target side 24. In this way, as the door 30 opens relative to the housing 20 from its self-sealed opening 22 state under the guidance of the hinge assembly 40, the door 30 moves towards the target side 24 of the housing 20, reducing the extent to which the door 30 extends beyond the outer wall of the housing 20. This reduces the risk of the door 30 interfering with or colliding with external structures during rotation. In other words, this embodiment allows for a reduction in the gap between the housing device and the external structure located beside it, achieving a micro-gap or even seamless level, which is beneficial for the housing device to be installed using an embedded method. Figure 5 The door 30 is shown to be open relative to the housing 20, with the opening 22 self-sealed under the guidance of the hinge assembly 40.

[0047] Compared to traditional hinges with a six-bar linkage design, the first swing arm 43 and the second swing arm 44 in this embodiment form a four-bar linkage mechanism. This means that the hinge assembly 40 in this embodiment has a simple structure and lower cost. At the same time, the hinge assembly 40 operates smoothly and stably, which is beneficial for stably guiding the door 30 to open and close. Furthermore, compared to traditional hinges with a track design, where debris easily accumulates in the track and affects the hinge operation, the debris accumulated at the location of the hinge assembly 40 in this embodiment is less likely to affect the swing of the swing arm. In other words, the debris accumulated at the location of the hinge assembly 40 in this embodiment has a smaller impact on the hinge assembly 40.

[0048] It should be noted that the rotatable connection between the pivot portion (i.e., the first to fourth pivot portions mentioned above) and the support member (i.e., the first to second support members mentioned above) can be in the form of a rod and hole fit. For example, the pivot portion is a rod structure, and the support member is provided with a pivot hole 48. The pivot portion is rotatably fitted into the pivot hole 48 on the support member, so that the pivot portion and the support member can rotate relative to each other, as shown in the figure. Of course, in other embodiments of the present invention, the pivot portion can also be a hole structure, and the support member is provided with a corresponding pivot rod to realize the rotatable connection between the pivot portion and the support member.

[0049] Furthermore, the pivot portion can be an integral structure with the pendulum rod, or it can be a separate structure independent of the pendulum rod. For example, the first to fourth pivot portions are all rod structures, and the first pivot portion 431 is a separate structure independent of the first pendulum rod 43, the second pivot portion 432 is an integral structure with the first pendulum rod 43, while the third pivot portion 441 and the fourth pivot portion 442 are separate structures independent of the second pendulum rod 44. The first pivot portion 431, the third pivot portion 441, and the fourth pivot portion 442 can be rivets or similar structures, and shims can also be added between the first pivot portion 431, the third pivot portion 441, and the fourth pivot portion 442 and the corresponding pendulum rod.

[0050] In one embodiment, the distance A between the first pivot 431 and the third pivot 441 is less than the distance C between the second pivot 432 and the fourth pivot 442, such as... Figure 3 As shown. In this way, as the door 30 rotates relative to the box 20 from the state of sealing the opening 22, the first swing arm 43 and the second swing arm 44 swing, which can guide the door 30 away from the box 20 to rotate, so that the door 30 unblocks the opening 22, allowing the user to store and retrieve items in the storage space 21 of the box 20.

[0051] It should be noted that the distance between different pivoting parts should be understood as the minimum distance between the central axes of the different pivoting parts. Specifically, the pivoting part and the supporting component rotate relative to each other about the central axis of the pivoting part.

[0052] In one embodiment, the enclosure device typically also includes a door seal (not identified) disposed on the door 30. The door 30 seals the opening 22 of the receiving space 21 through the door seal, so that the receiving space 21 can have a good sealing effect when the door 30 seals the opening 22.

[0053] When the door 30 is blocked at the opening 22, the first swing arm 43 moves closer to the target side 24 relative to the second swing arm 44. During the rotation of the door 30 relative to the housing 20 from the state of blocking the opening 22, the distance that the fourth pivot part 442 moves toward the housing 20 is less than the distance that the second pivot part 432 moves away from the housing 20. This makes the door 30 move away from the housing 20 as a whole, which can avoid the door seal being excessively squeezed and affecting the structural stability of the door seal, and at the same time can minimize the interference and collision between the door 30 and the housing 20.

[0054] Furthermore, when the door 30 blocks the opening 22, the second pivot 432 is closer to the target side 24 relative to the first pivot 431, that is, the first swing arm 43 is inclined toward the target side 24, such as... Figure 2 and Figure 3 As shown. In this way, it is beneficial to ensure that during the rotation of the door 30 relative to the housing 20 in the state of self-sealing the opening 22, the distance that the second pivot part 432 moves away from the housing 20 is greater than the distance that the fourth pivot part 442 moves towards the housing 20, thereby ensuring that the door 30 as a whole moves away from the housing 20.

[0055] Furthermore, the distance B between the first pivot 431 and the second pivot 432 is greater than the distance D between the third pivot 441 and the fourth pivot 442, as shown below. Figure 3 As shown. In this way, it is beneficial to ensure that during the rotation of the door 30 relative to the housing 20 in the state of self-sealing the opening 22, the distance that the second pivot part 432 moves away from the housing 20 is greater than the distance that the fourth pivot part 442 moves towards the housing 20, thereby ensuring that the door 30 as a whole moves away from the housing 20.

[0056] In one embodiment, the hinge assembly 40 further includes a stop 45. The stop 45 is disposed on the first support member 41 and / or the second support member 42. In other words, the stop 45 is disposed on the first support member 41, or the stop 45 is disposed on the second support member 42, or the stop 45 is connected to the first support member 41 and the second support member 42 respectively. Figure 4 The example illustrates a case where the stop 45 is located on the first support member 41. In this embodiment, the stop 45 is used to limit the maximum opening angle of the door 30.

[0057] Specifically, when the door 30 is blocked at the opening 22, the first swing arm 43 is closer to the target side 24 relative to the second swing arm 44. During the rotation of the door 30 relative to the housing 20 from its state of blocking the opening 22, the stop 45 abuts against the second swing arm 44 to limit the maximum opening angle of the door 30, such as... Figure 6 As shown. In other words, when the second swing arm 44 swings to abut the stop 45, the door body 30 reaches its maximum opening angle.

[0058] Furthermore, when the door 30 is blocked at the opening 22, the fourth pivot portion 442 of the second swing arm 44 moves away from the target side 24 relative to the third pivot portion 441. This increases the swing stroke of the second swing arm 44, thereby increasing the maximum opening angle of the door 30. For example, in this embodiment, the maximum opening angle of the door 30 can reach 90° or more, such as 120° or 150°. Moreover, it reduces the risk of interference or collision between the second swing arm 44 and the first pivot portion 431 of the first swing arm 43.

[0059] It should be noted that in this embodiment, by adjusting the posture of the second swing arm 44 when the door body 30 is blocked at the opening 22, the maximum swing stroke of the second swing arm 44 can be adjusted, thereby adjusting the maximum opening angle of the door body 30. Specifically, the maximum opening angle of the door body 30 is adjusted by adjusting the angle between the second swing arm 44 and the first direction when the door body 30 is blocked at the opening 22, where the first direction is perpendicular to the plane where the opening 22 is located.

[0060] In one embodiment, when the thickness of the door body 30 is 50mm, the distance A between the first pivot 431 and the third pivot 441 is 20±1mm, the distance B between the first pivot 431 and the second pivot 432 is 27.2±1mm, the distance C between the second pivot 432 and the fourth pivot 442 is 40±2mm, and the distance D between the third pivot 441 and the fourth pivot 442 is 20.4±1mm.

[0061] In an alternative embodiment, when the thickness of the door body 30 is 60 mm, the distance A between the first pivot 431 and the third pivot 441 is 24.5 ± 1 mm, the distance B between the first pivot 431 and the second pivot 432 is 36.4 ± 1 mm, the distance C between the second pivot 432 and the fourth pivot 442 is 50 ± 2 mm, and the distance D between the third pivot 441 and the fourth pivot 442 is 29.7 ± 1 mm.

[0062] In another alternative embodiment, when the thickness of the door body 30 is 77 mm, the distance A between the first pivot 431 and the third pivot 441 is 28 ± 1 mm, the distance B between the first pivot 431 and the second pivot 432 is 41.2 ± 1 mm, the distance C between the second pivot 432 and the fourth pivot 442 is 59 ± 2 mm, and the distance D between the third pivot 441 and the fourth pivot 442 is 36.9 ± 1 mm.

[0063] When the door body 30 of this embodiment has different thicknesses, by reasonably setting the distances A between the first pivot 431 and the third pivot 441, B between the first pivot 431 and the second pivot 432, C between the second pivot 432 and the fourth pivot 442, and D between the third pivot 441 and the fourth pivot 442 in the above manner, the degree to which the door body 30 extends beyond the outer wall of the housing 20 is reduced, and the degree to which the door body 30 presses against the door seal is reduced, which helps to reduce the risk of interference and collision of the door body 30 during rotation. In other words, the hinge assembly 40 disclosed in this embodiment can be applied to door bodies 30 of different thicknesses.

[0064] It should be noted that the thickness of the door body 30 should be understood as the length of the door body 30 in the first direction when the door body 30 is blocked in the opening 22.

[0065] Please refer to the following: Figure 7 and Figure 8 , Figure 7 This is a three-dimensional structural diagram of the box-shaped device of the present invention. Figure 8 yes Figure 7 The diagram shows the structure of region M of the box-shaped device.

[0066] In one embodiment, the first support member 41 and the housing 20 can be assembled and connected using fasteners such as screws. If the second support member 42 and the door 30 are also assembled and connected using fasteners such as screws, it will inevitably increase the distance between the second support member 42 and the door 30 in a third direction (e.g., Figure 8 As indicated by the middle arrow Z (the same applies below), the assembly tolerance requirements will be increased, and the assembly difficulty will also increase.

[0067] It should be noted that the third direction is perpendicular to the plane defined by the first and second directions. In other words, the third direction is the height direction of the door body 30. The assembly method using fasteners such as screws places high demands on the assembly tolerances in the height direction between the second load-bearing member 42 and the door body 30.

[0068] In view of this, in this embodiment, the second support member 42 and the door body 30 are assembled and connected by a shaft-hole fitting. Specifically, one of the second support member 42 and the door body 30 is provided with a connecting shaft 46, and the other is provided with a connecting hole 47. The connecting shaft 46 is embedded in the connecting hole 47 to fix the second support member 42 to the door body 30.

[0069] The second support member 42 and the door body 30 are connected by a shaft hole. The hinge assembly 40 can guide the opening and closing action of the door body 30 normally simply by inserting the connecting shaft 46 into the connecting hole 47. The depth requirement for the connecting shaft 46 to be inserted into the connecting hole 47 is low, which can reduce the assembly tolerance requirements between the second support member 42 and the door body 30 in the third direction and reduce the assembly difficulty.

[0070] Figure 8 An example is shown where the second support member 42 is provided with a connecting shaft 46 and the door body 30 is provided with a connecting hole 47.

[0071] Please see Figures 9 to 11 , Figure 9 yes Figure 7 A schematic diagram of another state of the box assembly shown. Figure 10 yes Figure 9 The diagram shows the structure of region N of the box-type device. Figure 11 This is a schematic diagram of an embodiment of the hinge assembly and drive mechanism of the present invention.

[0072] In one embodiment, the housing device further includes a drive mechanism 50. The drive mechanism 50 is tractively connected to at least one swing arm (including the first swing arm 43, the second swing arm 44, etc.) of the hinge assembly 40. The drive mechanism 50 drives the swing arm to swing, thereby causing the second support member 42 to rotate relative to the first support member 41. In this embodiment, the hinge assembly 40 is applied to the housing device described above, meaning it drives the door 30 to rotate relative to the housing 20. In other words, in this embodiment, the housing device achieves automatic opening and closing of the door 30 through the drive mechanism 50.

[0073] It should be noted that the hinge assembly 40 in this embodiment can be the hinge assembly 40 described in the above embodiments, that is, the hinge assembly 40 includes a first rocker arm 43 and a second rocker arm 44, and the drive mechanism 50 is transmittedly connected to at least one of the first rocker arm 43 and the second rocker arm 44. Of course, the hinge assembly 40 in this embodiment can also include more rocker arms, for example, the hinge assembly 40 in this embodiment adopts a six-bar linkage mechanism, etc., which is not limited here. The following description uses the hinge assembly 40 including the first rocker arm 43 and the second rocker arm 44 as an example, only for the purpose of discussion, and is not intended to limit the scope of the invention.

[0074] In one embodiment, the drive mechanism 50 includes a drive member 51. The drive member 51 serves as the power element of the drive mechanism 50, and is used to drive the swing arm of the hinge assembly 40 to swing, thereby causing the hinge assembly 40 to automatically open and close the door 30.

[0075] Optionally, the driving component 51 can be a motor, etc., which is not limited here.

[0076] The first swing arm 43 has a first pivot portion 431 and a second pivot portion 432, and the second swing arm 44 has a third pivot portion 441 and a fourth pivot portion 442, wherein each pivot portion adopts a rod structure. Considering that during the rotation of the door body 30, the pivot portion rotates relative to the load-bearing member, this embodiment allows the use of a driving component 51 such as a motor to drive the pivot portion to rotate, causing the swing arm to swing, thereby driving the hinge assembly 40 to move and drive the door body 30 to open and close. The door body 30 can be opened and closed by rotating the driving component 51 in both directions. It should be noted that the driving mechanism 50 in this embodiment can be connected to any one or more of the first to fourth pivot portions.

[0077] It is understood that the rotation law of the pivot part when the drive mechanism 50 drives the pivot part to rotate is the same as the rotation law of the pivot part when the user manually opens and closes the door.

[0078] Furthermore, considering that the door body 30 has sufficient space to accommodate the drive mechanism 50, and that the door body 30 conveniently conceals the drive mechanism 50, thus preventing the drive mechanism 50 from being exposed and affecting the overall appearance of the housing, this embodiment preferably places the drive mechanism 50 within the door body 30. Correspondingly, the drive mechanism 50 is drive-connected to the second pivot 432 and / or the fourth pivot 442. In other words, the drive mechanism 50 may be drive-connected only to the second pivot 432, or only to the fourth pivot 442, or both the second pivot 432 and the fourth pivot 442 may be drive-connected.

[0079] Furthermore, when the door 30 is blocked at the opening 22, the first rocker arm 43 is closer to the target side 24 relative to the second rocker arm 44. In other words, at this time, the second pivot 432 is closer to the target side 24 relative to the fourth pivot 442, that is, the fourth pivot 442 is located at the edge of the door 30, and the space it can provide is limited. Therefore, in this embodiment, the drive mechanism 50 is preferably connected to the second pivot 432 through transmission, thereby maximizing the convenience of setting the drive mechanism 50 in the door 30 and realizing the transmission connection between the drive mechanism 50 and the hinge assembly 40, such as... Figure 10 and Figure 11 As shown.

[0080] In one embodiment, the drive mechanism 50 further includes a bracket 52 and a coupling 53. When the drive mechanism 50 is located on the door body 30, the bracket 52 is located on the door body 30, and the drive member 51 is located on the bracket 52; that is, the drive member 51 is located on the door body 30 via the bracket 52. Furthermore, the drive member 51 is driveably connected to the second pivot 432 and / or the fourth pivot 442 via the coupling 53.

[0081] For traditional hinges that use a track design, it is difficult for the motor and other drive components 51 to move the shaft along the track. In other words, traditional hinges are limited by their structural design and it is difficult to achieve automatic opening and closing of the door 30. However, the hinge assembly 40 in this embodiment adopts a rocker arm design, which makes it easy for the motor and other drive components 51 to swing the rocker arm. This is because the hinge assembly 40 in this embodiment can be adapted to the driving method of the drive mechanism 50, thus facilitating the automatic opening and closing of the door 30.

[0082] In one embodiment, the housing assembly may further include a damping element (not shown). Any one or more of the first to fourth pivoting sections described in the above embodiments may be provided with a damping element to increase the damping force experienced by the pivoting section during rotation.

[0083] This embodiment achieves the stop-and-go function of the door 30 through a damping element. Specifically, during the rotation of the door 30, when the door 30 is suspended at any angle, the damping force provided by the damping element can keep the door 30 stopped at the current position. When the user or the aforementioned drive mechanism 50 applies sufficient driving force to the door 30, the driving force overcomes the damping force, thereby causing the door 30 to start rotating again.

[0084] Furthermore, in this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
