Description

Technical Field

[0001] The present invention relates to the field of lifting mechanisms, and in particular to a lifting structure and a disinfection cabinet and a terminal product using the same. Background Art

[0002] In modern furniture and home appliances, products with internal storage space (such as disinfection cabinets, dishwashers, refrigerators, wardrobes, cabinets, etc.) usually adopt drawer-type structures, such as drawers and pull-out baskets, to achieve layered storage of items. Such drawer-type structures achieve horizontal pulling and pulling movements through guide rail components, making it easier for users to store and access internal items. However, as users' demands for space utilization and operational convenience increase, the single pulling and pulling mode of traditional drawer-type structures has gradually exposed technical limitations.

[0003] Traditional drawer structures can only be pulled out horizontally, and their height is fixed after installation. When users need to take or place items on a drawer structure located at a lower position, they often need to bend over, which provides a poor operating experience and is laborious, especially for users with limited mobility, such as the elderly and pregnant women.

[0004] Therefore, it is necessary to develop a lifting structure for furniture and household appliances to solve the problem that the drawer-type structure in the current furniture and household appliances cannot be lifted, resulting in insufficient convenience in use. Summary of the invention

[0005] Based on this, the present invention provides a lifting structure, including a lifting assembly, the lifting assembly including a first mounting part and a connecting part connected to the first mounting part through a connecting unit, the connecting part including two working positions, namely a storage position and a lifting position, the storage position is located below the first mounting part, and the lifting position is located above the front side of the first mounting part; the connecting unit includes a first connecting arm whose upper end is rotatably connected to the first mounting part, and a second connecting arm whose front end is connected to the connecting part, and the lower end of the first connecting arm and the rear end of the second connecting arm are rotatably connected; the connecting unit also includes a third connecting arm, the two ends of the third connecting arm are respectively rotatably connected to the first mounting part and the second connecting arm, and the third connecting arm is configured to limit the second connecting arm during the process of the first connecting arm swinging forward relative to the first mounting part and moving the connecting part from the storage position to the lifting position, so that the front end of the second connecting arm swings upward relative to its rear end until the connecting part moves to the lifting position.

[0006] In the present invention, the lifting assembly is installed in the accommodation space of furniture or household appliances and is used to install the drawer-type structure of the furniture or household appliances, such as a drawer, a pull-out basket, etc., in the accommodation space thereof.

[0007] In the present invention, the first mounting portion of the lifting assembly can be a part of the furniture or household appliance itself, or it can be an independent component, which is used to fix the lifting assembly to the furniture or household appliance; the connecting portion of the lifting assembly is used for the installation of the drawer-type structure, so that the drawer-type structure is installed in the accommodating space of the furniture or household appliance, wherein the drawer-type structure is a containing structure installed on the connecting portion by means of horizontally arranged guide rails, such as a drawer, a pull-out basket, etc., which can be pulled and moved in a horizontal direction relative to the connecting portion.

[0008] In the present invention, the first connecting arm in the connecting unit can be rotatably installed on the first mounting part through its upper end in a vertical plane, the second connecting arm can be rotatably installed on the connecting part through its front end in a vertical plane, the first connecting arm and the second connecting arm are rotatably connected to each other, and the connecting part is connected to the first mounting part through the connecting unit. Therefore, the connecting part can move relative to the first mounting part, and its moving path is limited by the connecting unit. Its moving process is: when the drawer-type structure is pulled out from the accommodating space of furniture or household appliances, the connecting part will be driven to move forward out of the accommodating space. During this process, the connecting part realizes its movement through the forward swing of the first connecting arm relative to the first mounting part, and the swing of the second connecting arm relative to the first connecting arm, so that the connecting part leaves the accommodating space and moves from the storage position to the lifting position. At this time, the drawer-type structure installed on the connecting part will move forward and lift with the movement of the connecting part, thereby achieving the effect of lifting the drawer-type structure in furniture and household appliances and improving its convenience of use. The third connecting arm limits the second connecting arm, and is used to enable the front end of the second connecting arm to swing upward relative to the rear end thereof when the drawer-type structure is pulled out of the accommodating space, so as to realize the lifting of the connecting part by the second connecting arm.

[0009] In addition, in the present invention, the lifting of the connection part by the connection unit is divided into two sections, namely, the lifting of the second connection arm by the first connection arm, and the lifting of the connection part by the second connection arm, that is, the lifting height of the connection part is the sum of the lifting heights of the first connection arm and the second connection arm. Therefore, compared with the one-stage lifting structure, the present invention can reduce the requirements for the lifting height of the first connection arm under the premise of ensuring the same lifting height of the connection part, that is, the first connection arm requires a smaller space for movement. Therefore, the present invention can be applied to furniture and household appliances with smaller accommodating space under the premise of ensuring that the lifting height of the connection part meets the requirements, and has strong applicability. Among them, it is worth noting that when installing the lifting assembly, its installation position needs to enable the second connection arm to move out of the accommodating space during the lifting process of the first connection arm, so that the lifting of the second connection arm will not be limited by the accommodating space and can be smoothly lifted relative to the first connection arm.

[0010] Further, the first connecting arm includes a first connecting member and a second connecting member. The upper ends of the first connecting member and the second connecting member are both hinged to the first mounting portion, respectively forming a first hinge point and a second hinge point. The second connecting arm includes a third connecting member and a fourth connecting member. The front ends of the third connecting member and the fourth connecting member are both hinged to the connecting portion, forming a third hinge point and a fourth hinge point. The lower end of the first connecting member is hinged to the rear end of the third connecting member, forming a fifth hinge point. The lower end of the second connecting member is hinged to the rear end of the fourth connecting member, forming a sixth hinge point. A fifth connecting member is connected between the fifth hinge point and the sixth hinge point, and the fifth connecting member is respectively hinged to the fifth hinge point and the sixth hinge point. Among them, the first hinge point, the second hinge point, the fifth hinge point, and the sixth hinge point form a parallelogram, and the third hinge point, the fourth hinge point, the fifth hinge point, and the sixth hinge point form a parallelogram.

[0011] In the present invention, the hinge connection structures between the first mounting portion, the first connecting member, the second connecting member, the third connecting member, the fourth connecting member, the fifth connecting member, and the connecting portion can be shaft structures, bearing structures, etc. Among them, the rotational connection structure between the first connecting arm and the first mounting portion is formed by the hinge structures between the first connecting member and the second connecting member and the first mounting portion. The rotational connection structure between the second connecting arm and the connecting portion is formed by the hinge structures between the third connecting member and the fourth connecting member and the connecting portion. The rotational connection structure between the first connecting arm and the second connecting arm is formed by the hinge structures between the first connecting member and the second connecting member and the third connecting member and the fourth connecting member.

[0012] In the present invention, since the first hinge point, the second hinge point, the fifth hinge point, and the sixth hinge point form a parallelogram, and the third hinge point, the fourth hinge point, the fifth hinge point, and the sixth hinge point form a parallelogram, therefore, the straight line where the third hinge point and the fourth hinge point are located will always be parallel to the straight line where the first hinge point and the second hinge point are located. And the angle of the straight line where the first hinge point and the second hinge point are located is fixed. Therefore, the connecting portion connected to the second connecting arm through the third hinge point and the fourth hinge point will not deflect during the movement, and it can ensure that the drawer-type structure mounted thereon always remains stable.

[0013] Further, the third connecting arm includes a first limiting member. The first limiting member is respectively hinged to the first mounting portion and the fourth connecting member. The first limiting member is configured to limit the fourth connecting member when the first connecting arm swings forward relative to the first mounting portion, so that the front end of the fourth connecting member swings upward relative to its rear end.

[0014] In the present invention, the first limit member is hinged to the first mounting portion and the fourth connecting member respectively. Therefore, when the first connecting arm swings forward and drives the second connecting arm connected thereto to move forward, the first limit member will pull and limit the fourth connecting member, thereby pulling the fourth connecting rod toward the first mounting portion, so that the front end of the fourth connecting member swings upward relative to its rear end, thereby realizing the lifting of the connecting portion by the second connecting arm.

[0015] Furthermore, the third connecting arm includes a second limiting member, which is hinged to the first mounting portion and the third connecting member respectively, and the first limiting member is configured to limit the third connecting member when the first connecting arm swings forward relative to the first mounting portion, so that the front end of the third connecting member swings upward relative to its rear end.

[0016] In the present invention, like the first limiting member, the second limiting member can also pull the third connecting member connected thereto toward the first mounting portion during the forward swinging of the first connecting arm, so that the front end of the third connecting member swings upward relative to the rear end thereof, thereby realizing the lifting of the connecting portion by the second connecting arm.

[0017] Among them, the first limit member and the second limit member can exist separately in the lifting assembly, or the first limit member and the second limit member. If the third connecting arm includes the first limit member and the second limit member at the same time, that is, the first limit member and the second limit member, the first limit member and the second limit member, the strength and reliability of the supporting structure of the third connecting arm for the second connecting arm can be further increased, which can effectively improve the structural stability of the second connecting arm.

[0018] Furthermore, the lifting structure includes two lifting assemblies arranged opposite to each other, and the connecting parts of the two lifting assemblies are fixedly connected to each other through a connecting rod.

[0019] In the present invention, the lifting structure includes two lifting components arranged opposite to each other. When in use, the two lifting components are respectively installed on both sides of the accommodating space and are used to be connected to both sides of the drawer-type structure, which can effectively improve the structural stability of the drawer-type structure installed in the accommodating space through the lifting structure. Among them, the connecting rod connected between the connecting parts of the two lifting components can further enhance the structural stability of the lifting structure, thereby further enhancing the structural stability of the drawer-type structure installed in the accommodating space.

[0020] Furthermore, the first limit member is plate-shaped and is located on a side of the lifting component facing away from another lifting component. When the connecting portion of the first limit member is in a raised position, the first limit member blocks the connection unit setting of the lifting component where it is located in the horizontal direction.

[0021] In the present invention, the first stopper blocks the connection unit of the lifting assembly in the horizontal direction, which means that the projection of the connection unit in the horizontal direction is located inside the first stopper. That is, when the drawer-type structure is pulled out and the connection part is in the lifting position, the first stopper can block the connection unit in the horizontal direction. At this time, the user cannot directly see the connection unit from the outside, which can effectively improve the aesthetics of the lifting assembly when in use.

[0022] Furthermore, it also includes a driving component, which is connected to the connecting unit, and the driving component is configured to fix the position of the connecting part when the connecting part is located in the storage position and the lifting position.

[0023] In the present invention, the driving assembly is used to fix the position of the connecting part when the connecting part is in the storage position and the lifting position, that is, to fix the position of the drawer-type structure, so that the drawer-type structure can be fixed relative to the furniture or household appliance when the drawer-type structure is stored in the accommodating space and is fully pulled out.

[0024] Further, the driving assembly includes a driving arm fixedly connected to the first connecting member through a connecting shaft, and the axis of the connecting shaft coincides with the rotation axis of the first connecting member; the driving assembly also includes a second mounting portion, a hinge shaft parallel to the connecting shaft is formed on the second mounting portion, an elastic compression member is hinged on the hinge shaft, an end of the elastic compression member away from the hinge shaft is hinged to an end of the driving arm away from the connecting shaft, and the hinge point between the elastic compression member and the connecting arm is located in the area between the hinge shaft and the connecting shaft; a first limiting column and a second limiting column are provided on the second mounting portion corresponding to the driving arm on its rotation path, and the first limiting column and the second limiting column are respectively located on both sides of the plane where the axis of the connecting shaft and the axis of the hinge shaft are located; wherein, when the connecting portion is in the accommodating position, the driving arm abuts against the first limiting column, and the elastic compression member is in a compressed state or a natural state at this time; when the connecting portion is in the lifting position, the driving arm abuts against the second limiting column, and the elastic compression member is in a compressed state or a natural state at this time.

[0025] In the present invention, the second mounting portion may be a component independent of the first mounting portion, or may be the same component as the first mounting portion, and is used for mounting the elastic compression member.

[0026] In the present invention, the hinge point between the elastic compression member and the connecting arm is located in the area between the hinge shaft and the connecting shaft, which means that the projection of the hinge point on the plane where the axes of the hinge shaft and the connecting shaft are located is located between the axes of the hinge shaft and the connecting shaft. Among them, since the elastic compression member is connected between the driving arm and the hinge shaft, the driving arm will be pushed by the elastic compression member to press against the first limiting column or the second limiting column, thereby completing the fixation of the driving arm, that is, achieving the fixation of the first connecting member connected thereto. At this time, the position of the third connecting member connected to the first connecting member and the connecting portion connected to the third connecting member will also be fixed, that is, the effect of fixing the position of the drawer-type structure can be achieved.

[0027] In addition, in the present invention, during the swinging of the first connecting arm, the driving arm will swing in the same direction as the first connecting member, and since the first limiting column and the second limiting column are respectively located on both sides of the plane where the axis of the connecting shaft and the axis of the hinge shaft are located, the elastic compression member will be gradually compressed during the process of the driving arm moving from abutting against the first limiting column to abutting against the second limiting column, and from abutting against the second limiting column to abutting against the first limiting column, i.e., preventing the driving arm from rotating until the hinge point of the elastic compression member and the driving arm and the connecting shaft and the hinge shaft are in the same straight line. This is the critical point, and the compression amount reaches the maximum. After passing the critical point, the elastic compression member will gradually stretch, i.e., push the driving arm to rotate until the driving arm abuts against the second limiting column or the first limiting column. It can be seen that when the user pulls out or pushes back the drawer-type structure from furniture or household appliances, after passing the critical point, the thrust of the elastic compression member on the driving arm can assist the pulling out or pushing back process, and can improve the convenience of the pulling out and pushing back process of the drawer-type structure to a certain extent.

[0028] In addition, the present invention also provides a disinfection cabinet, which includes the above-mentioned lifting structure.

[0029] In the present invention, the disinfection cabinet comprises a shell, a containing space is formed in the shell, a containing structure is contained in the containing space, and the containing structure is installed on the side wall of the containing space through the lifting assembly.

[0030] In addition, the present invention also provides a terminal product, which includes the above-mentioned lifting structure.

[0031] In the present invention, a containing space is formed in the terminal product, and a containing structure is contained in the containing space. The containing structure is installed on the side wall of the containing space through the lifting assembly.

[0032] The principle and effect of the present invention are further described below in combination with the above technical solutions and the accompanying drawings: In the present invention, the connecting part moves by the forward swing of the first connecting arm relative to the first mounting part and the upward swing of the second connecting arm relative to the first connecting arm, so that the connecting part moves from the storage position to the lifting position. During this process, the drawer-type structure installed on the connecting part will be lifted as the connecting part moves, thereby achieving the effect of lifting the drawer-type structure in furniture and household appliances and improving their convenience of use.

[0033] In addition, in the present invention, the lifting of the connecting part by the connecting unit is divided into two sections, namely, the lifting of the connecting part by the first connecting arm, and the lifting of the connecting part by the second connecting arm, that is, the lifting height of the connecting part is the sum of the lifting heights of the first connecting arm and the second connecting arm. Therefore, compared with the one-stage lifting structure, the present invention can reduce the requirement for the lifting height of the first connecting arm while ensuring the same lifting height of the connecting part, that is, the first connecting arm needs a smaller movable space. Therefore, the present invention can be suitable for furniture and household appliances with smaller accommodating space while ensuring that the lifting height of the connecting part meets the requirements, and has strong applicability.

DETAILED DESCRIPTION

[0036] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0038] In order to facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments: like Figure 1-10A lifting structure includes a lifting assembly, wherein the lifting assembly includes a first mounting portion 11 and a connecting portion 12 connected to the first mounting portion 11 through a connecting unit, wherein the connecting portion 12 includes two working positions, namely a storage position and a lifting position, wherein the storage position is located below the first mounting portion 11, and the lifting position is located above the front side of the first mounting portion 11; the connecting unit includes a first connecting arm 13 whose upper end is rotatably connected to the first mounting portion 11, and a second connecting arm 14 whose front end is connected to the connecting portion 12, and the first connecting arm 13 is connected to the first mounting portion 11. The lower end of a connecting arm 13 and the rear end of the second connecting arm 14 are rotatably connected; the connecting unit also includes a third connecting arm, the two ends of which are rotatably connected to the first mounting portion 11 and the second connecting arm 14, respectively, and the third connecting arm is configured to limit the second connecting arm 14 when the first connecting arm 13 swings forward relative to the first mounting portion 11 and moves the connecting portion 12 from the storage position to the lifting position, so that the front end of the second connecting arm 14 swings upward relative to its rear end until the connecting portion 12 moves to the lifting position.

[0039] In the present invention, the lifting assembly is installed in the accommodation space of furniture or household appliances and is used to install the drawer-type structure 2 of the furniture or household appliances, such as a drawer or a pull-out basket, in the accommodation space.

[0040] In the present invention, the first mounting portion 11 of the lifting assembly can be a part of the furniture or household appliance itself, or it can be an independent component, which is used to fix the lifting assembly to the furniture or household appliance; the connecting portion 12 of the lifting assembly is used for the installation of the drawer-type structure 2, so that the drawer-type structure 2 is installed in the accommodating space of the furniture or household appliance, wherein the drawer-type structure 2 is a containing structure 21 installed on the connecting portion 12 by a horizontally arranged guide rail 22, such as a drawer, a pull-out basket, etc., which can be pulled and moved in the horizontal direction relative to the connecting portion 12.

[0041] In the present invention, the first connecting arm 13 in the connecting unit is rotatably mounted on the first mounting portion 11 through its upper end in a vertical plane, the second connecting arm 14 is rotatably mounted on the connecting portion 12 through its front end in a vertical plane, the first connecting arm 13 and the second connecting arm 14 are rotatably connected to each other, and the connecting portion 12 is connected to the first mounting portion 11 through the connecting unit. Therefore, the connecting portion 12 can move relative to the first mounting portion 11, and its moving path is limited by the connecting unit. The moving process is: when the drawer-type structure 2 is pulled out from the accommodation space of the furniture or household appliance, When the drawer 12 is pulled out of the storage space, the connecting portion 12 is driven to move forward out of the storage space. During this process, the connecting portion 12 is moved by the first connecting arm 13 swinging forward relative to the first mounting portion 11, and the second connecting arm 14 swinging relative to the first connecting arm 13, so that the connecting portion 12 leaves the storage space and moves from the storage position to the lifting position. At this time, the drawer-type structure 2 installed on the connecting portion 12 will move forward and lift with the movement of the connecting portion 12, thereby achieving the effect of lifting the drawer-type structure 2 in furniture and household appliances and improving its convenience of use. Among them, the third connecting arm has a limiting effect on the second connecting arm 14, and is used to make the front end of the second connecting arm 14 swing upward relative to its rear end when the drawer-type structure 2 is pulled out of the storage space, so as to achieve the lifting of the connecting portion 12 by the second connecting arm 14.

[0042] In addition, in the present invention, the lifting of the connection part 12 by the connection unit is divided into two sections, namely, the lifting of the second connection arm 14 by the first connection arm 13, and the lifting of the connection part 12 by the second connection arm 14, that is, the lifting height of the connection part 12 is the sum of the lifting heights of the first connection arm 13 and the second connection arm 14. Therefore, compared with the one-stage lifting structure, the present invention can reduce the requirements for the lifting height of the first connection arm 13 on the premise of ensuring the same lifting height of the connection part 12, that is, the first connection arm 13 requires a smaller space for movement. Therefore, the present invention can be applied to furniture and household appliances with smaller accommodating space on the premise of ensuring that the lifting height of the connection part 12 meets the requirements, and has strong applicability. Among them, it is worth noting that when installing the lifting assembly, its installation position needs to enable the second connection arm 14 to move out of the accommodating space during the lifting process of the first connection arm 13, so that the lifting of the second connection arm 14 will not be limited by the accommodating space and can be smoothly lifted relative to the first connection arm 13.

[0043] In one embodiment, the first connecting arm 13 includes a first connecting member 131 and a second connecting member 132, and the upper ends of the first connecting member 131 and the second connecting member 132 are hinged to the first mounting portion 11 to form a first hinge point A and a second hinge point B respectively; the second connecting arm 14 includes a third connecting member 141 and a fourth connecting member 142, and the front ends of the third connecting member 141 and the fourth connecting member 142 are hinged to the connecting portion 12 to form a third hinge point C and a fourth hinge point D; the lower end of the first connecting member 131 is hinged to the third connecting member 1 The rear end of the second connecting member 132 is hinged to the rear end of the fourth connecting member 142 to form a sixth hinge point F, and a fifth connecting member 15 is connected between the fifth hinge point E and the sixth hinge point F, and the fifth connecting member 15 is hinged to the fifth hinge point E and the sixth hinge point F respectively; wherein, the first hinge point A, the second hinge point B, the fifth hinge point E and the sixth hinge point F form a parallelogram, and the third hinge point C, the fourth hinge point D, the fifth hinge point E and the sixth hinge point F form a parallelogram.

[0044] In this embodiment, the hinged connection structure between the first mounting portion 11, the first connecting member 131, the second connecting member 132, the third connecting member 141, the fourth connecting member 142, the fifth connecting member 15 and the connecting portion 12 can be a shaft structure, a bearing structure, etc. Among them, the rotational connection structure between the first connecting arm 13 and the first mounting portion 11 is formed by the hinged structure between the first connecting member 131 and the second connecting member 132 and the first mounting portion 11, the rotational connection structure between the second connecting arm 14 and the connecting portion 12 is formed by the hinged structure between the third connecting member 141 and the fourth connecting member 142 and the connecting portion 12, and the rotational connection structure between the first connecting arm 13 and the second connecting arm 14 is formed by the hinged structure between the first connecting member 131 and the second connecting member 132 and the third connecting member 141 and the fourth connecting member 142.

[0045] In this embodiment, since the first hinge point A, the second hinge point B, the fifth hinge point E and the sixth hinge point F form a parallelogram, the third hinge point C, the fourth hinge point D, the fifth hinge point E and the sixth hinge point F form a parallelogram, the straight line where the third hinge point C and the fourth hinge point D are located will always be parallel to the straight line where the first hinge point A and the second hinge point B are located, and the angle of the straight line where the first hinge point A and the second hinge point B are located is fixed. Therefore, the connecting part 12 connected to the second connecting arm 14 through the third hinge point C and the fourth hinge point D will not deflect during the movement, which can ensure that the drawer-type structure 2 installed thereon always remains stable.

[0046] In one embodiment, the third connecting arm includes a first limiting member 16, and the first limiting member 16 is hinged to the first mounting portion 11 and the fourth connecting member 142 respectively, and the first limiting member 16 is configured to limit the fourth connecting member 142 when the first connecting arm 13 swings forward relative to the first mounting portion 11, so that the front end of the fourth connecting member 142 swings upward relative to its rear end.

[0047] In this embodiment, the first limit member 16 is hinged to the first mounting portion 11 and the fourth connecting member 142 respectively. Therefore, when the first connecting arm 13 swings forward and drives the second connecting arm 14 connected thereto to move forward, the first limit member 16 will pull and limit the fourth connecting member 142, thereby pulling the fourth connecting rod toward the first mounting portion 11, so that the front end of the fourth connecting member 142 swings upward relative to its rear end, thereby realizing the lifting of the connecting portion 12 by the second connecting arm 14.

[0048] In one embodiment, the third connecting arm includes a second limiting member 17, and the second limiting member 17 is hinged to the first mounting portion 11 and the third connecting member 141 respectively. The first limiting member 16 is configured to limit the third connecting member 141 when the first connecting arm 13 swings forward relative to the first mounting portion 11, so that the front end of the third connecting member 141 swings upward relative to its rear end.

[0049] In this embodiment, similar to the first stopper 16, the second stopper 17 can also pull the third connection member 141 connected thereto toward the first mounting portion 11 during the process of the first connection arm 13 swinging forward, so that the front end of the third connection member 141 swings upward relative to the rear end thereof, thereby realizing the lifting of the connection portion 12 by the second connection arm 14. The first stopper 16 and the second stopper 17 can exist separately in the lifting assembly, or the first stopper 16 and the second stopper 17 can be used. If the third connection arm includes both the first stopper 16 and the second stopper 17, that is, the first stopper 16 and the second stopper 17, the strength and reliability of the support structure of the third connection arm for the second connection arm 14 can be further increased, and the structural stability of the second connection arm 14 can be effectively improved.

[0050] In one embodiment, the lifting structure includes two lifting components that are arranged opposite to each other, and the connecting parts 12 of the two lifting components are fixedly connected to each other through a connecting rod.

[0051] In this embodiment, the lifting structure includes two lifting components arranged opposite to each other. When in use, the two lifting components are respectively installed on both sides of the accommodating space and are used to be connected to both sides of the drawer-type structure 2, which can effectively improve the structural stability of the drawer-type structure 2 installed in the accommodating space through the lifting structure. Among them, the connecting rod connected between the connecting parts 12 of the two lifting components can further enhance the structural stability of the lifting structure, thereby further enhancing the structural stability of the drawer-type structure 2 installed in the accommodating space.

[0052] In one embodiment, the first limiting member 16 is plate-shaped and is located on a side of the lifting component facing away from another lifting component. When the connecting portion 12 is in the raised position, the first limiting member 16 blocks the connection unit setting of the lifting component in the horizontal direction.

[0053] In this embodiment, the first stopper 16 blocks the connection unit of the lifting assembly in the horizontal direction, which means that the projection of the connection unit in the horizontal direction is located inside the first stopper 16. That is, when the drawer-type structure 2 is pulled out and the connection part 12 is in the lifting position, the first stopper 16 can block the connection unit in the horizontal direction. At this time, the user cannot directly see the connection unit from the outside, which can effectively improve the aesthetics of the lifting assembly when in use.

[0054] One embodiment further includes a driving assembly, wherein the driving assembly is connected to the connecting unit, and the driving assembly is configured to fix the position of the connecting portion 12 when the connecting portion 12 is located in the storage position and the lifting position.

[0055] In this embodiment, the driving assembly is used to fix the position of the connecting portion 12 when the connecting portion 12 is in the storage position and the lifting position, that is, to fix the position of the drawer-type structure 2, so that the drawer-type structure 2 can be stored in the accommodating space and fully pulled out, so that the drawer-type structure 2 can be fixed relative to the furniture or household appliance.

[0056] In one embodiment, the driving assembly includes a driving arm 19 fixedly connected to the first connecting member 131 through a connecting shaft 191, and the axis of the connecting shaft 191 coincides with the rotation axis of the first connecting member 131; the driving assembly further includes a second mounting portion 18, on which a hinge shaft 184 parallel to the connecting shaft 191 is formed, and an elastic compression member 181 is hinged to the hinge shaft 184. One end of the elastic compression member 181 away from the hinge shaft 184 is hinged to one end of the driving arm 19 away from the connecting shaft 191, and the hinge point of the elastic compression member 181 and the connecting arm is located in the area between the hinge shaft 184 and the connecting shaft 191; on the second mounting portion 18, a first limiting post 182 and a second limiting post 183 are arranged corresponding to the driving arm 19 on its rotation path, and the first limiting post 182 and the second limiting post 183 are respectively located on both sides of the plane where the axis of the connecting shaft 191 and the axis of the hinge shaft 184 are located; wherein, when the connecting portion 12 is in the receiving position, the driving arm 19 abuts against the first limiting post 182, and at this time the elastic compression member 181 is in a compressed state or a natural state, and when the connecting portion 12 is in the lifting position, the driving arm 19 abuts against the second limiting post 183, and at this time the elastic compression member 181 is in a compressed state or a natural state. Preferably, the elastic compression member 181 is a gas spring.

[0057] In this embodiment, the second mounting portion 18 can be a component independent of the first mounting portion 11, or can be the same component as the first mounting portion 11, and it is used for the installation of the elastic compression member 181.

[0058] In this embodiment, the hinge point of the elastic compression member 181 and the connecting arm being located in the area between the hinge shaft 184 and the connecting shaft 191 means that the projection of this hinge point on the plane where the axes of the hinge shaft 184 and the connecting shaft 191 are located is between the axes of the hinge shaft 184 and the connecting shaft 191. Since an elastic compression member 181 is connected between the driving arm 19 and the hinge shaft 184, the driving arm 19 will be pushed by the thrust from the elastic compression member 181 and pushed to abut against the first limiting post 182 or the second limiting post 183, thereby completing the fixation of the driving arm 19, that is, realizing the fixation of the first connecting member 131 connected thereto. At this time, the position of the third connecting member 141 connected to the first connecting member 131 and the connecting portion 12 connected to the third connecting member 141 will also be fixed, that is, the effect of fixing the position of the drawer-type structure 2 can be achieved.

[0059] In addition, in this embodiment, during the swinging process of the first connecting arm 13, the driving arm 19 will swing in the same direction as the first connecting member 131. Since the first limiting post 182 and the second limiting post 183 are respectively located on both sides of the plane where the axis of the connecting shaft 191 and the axis of the hinge shaft 184 are located, during the process of the driving arm 19 moving from abutting against the first limiting post 182 to abutting against the second limiting post 183 and from abutting against the second limiting post 183 to abutting against the first limiting post 182, the elastic compression member 181 will be gradually compressed, that is, it prevents the driving arm 19 from rotating until the hinge point of the elastic compression member 181 and the driving arm 19, the connecting shaft 191, and the hinge shaft 184 are on the same straight line. At this time, it is the critical point, and the compression amount reaches the maximum. After crossing the critical point, the elastic compression member 181 will gradually expand, that is, it pushes the driving arm 19 to rotate until the driving arm 19 abuts against the second limiting post 183 or the first limiting post 182. It can be seen that when the user pulls out or pushes back the drawer-type structure 2 from furniture or household appliances, after passing the critical point, the thrust of the elastic compression member 181 on the driving arm 19 can assist in the pulling-out or pushing-back process, and can improve the convenience of the pulling-out and pushing-back processes of the drawer-type structure 2 to a certain extent.
