Description

Technical Field

[0001] The present application relates to the technical field of wardrobe lifting rod devices, and in particular to a lifting rod device and a wardrobe provided with the lifting rod device. Background Art

[0002] A general wardrobe is usually divided into two layers, and in order to hang clothes conveniently, users usually put clothes on the lower layer, but in this way the clothes are closer to the ground and are prone to moisture. In addition, if some seldom-used clothes occupy the lower layer for a long time, they will occupy the space of the lower wardrobe control, making it impossible to place the frequently-used clothes.

[0003] In order to hang clothes at a high level and make it convenient to hang and take them out, there are currently some lifting clothes rod devices that can achieve automatic flipping. Figure 1 As shown, the lifting clothes rod device is arranged in the upper cabinet of the wardrobe, with a clothes hanging rod in the middle and swing rods at both ends. A motor drive box is installed at the bottom of the swing rod, and a drive motor and a gear box are arranged in each motor drive box. The drive motor drives the swing rod to rotate clockwise and counterclockwise through a transmission mechanism such as a gear box and a screw rod, thereby driving the clothes hanging rod to rise and fall. Since two drive motors are arranged to drive the rotation of the two swing rods respectively, the two drive motors need to be synchronized, so each drive box is usually also provided with an encoder to synchronize and coordinate the two drive motors.

[0004] The above-mentioned clothes rod lifting device has the following problems:

[0005] 1. Because drive boxes are set on both sides, each drive box must be equipped with a drive motor, a transmission mechanism and an encoder, which makes the drive box thicker, not thin enough, and protrudes significantly in the cabinet body, occupying more internal space of the wardrobe.

[0006] 2. Since both drive boxes are equipped with motors, the cabinet positions corresponding to the two drive boxes need to have pre-buried wire troughs on the side of the cabinet so that the motor leads can be led to the back to connect with the controller, which increases the difficulty of installation.

[0007] 3. In order to balance the rotation support force of the two swing arms, two drive motors are required, and corresponding encoders are set for coordination, which is expensive and not conducive to promotion and application. Summary of the invention

[0008] Based on this, the purpose of the present application is to provide a liftable clothes rod device with a small lateral thickness and requiring only one driving motor, and a wardrobe having the liftable clothes rod device.

[0009] As an aspect of the present application, a liftable clothes rod device is provided, which includes a housing, a lever transmission assembly disposed in the middle of the housing, two link assemblies respectively disposed on both sides of the housing and respectively in transmission connection with the lever transmission assembly, a drive assembly for driving at least one link assembly to move, two swing rod assemblies respectively assembled at the ends of the two link assemblies, and a clothes hanging rod assembly disposed between the two swing rod assemblies; the drive assembly is in transmission connection with at least one link assembly to drive at least one of the link assemblies to move, and the lever transmission assembly makes the two link assemblies move synchronously through the transmission connection with the two link assemblies. The two link assemblies respectively drive the two swing rod assemblies to rotate and swing in a plane parallel to the side surface of the housing, driving the clothes hanging rod assembly to rise and fall.

[0010] As another aspect of the present application, a wardrobe equipped with the above liftable clothes rod device is provided, which includes a wardrobe body and the above liftable clothes rod device. The liftable clothes rod device is installed inside the wardrobe body, the middle part of the housing is fixed to the back panel of the wardrobe body, and both sides of the housing are respectively fixed to the side panels of the wardrobe body.

[0011] In the liftable clothes rod device of the present application, the lever transmission assembly disposed in the middle of the housing is respectively in transmission connection with the two link assemblies disposed on both sides of the housing. The two link assemblies on both sides are respectively assembled with swing rod assemblies. The drive assembly does not directly connect to drive the swing rod assemblies, but drives the swing rod assemblies through the link assemblies. Therefore, it is not necessary to directly dispose both the drive assembly and the transmission mechanism in the drive box. And the drive assembly only needs to drive at least one link assembly to move, and can synchronously drive the two swing rod assemblies to rotate and swing through the lever transmission assembly, so that the clothes hanging rod assembly installed on the two swing rod assemblies rises or falls, facilitating the user to hang clothes and raise the clothes. It is also not necessary to separately provide drive motors for the swing rods on both sides, reducing the occupation of the internal space of the wardrobe by the drive box; there is no need to set an encoder, reducing the cost. At the same time, only the lead wire of the drive motor needs to be set on one side, making the installation more convenient and more conducive to the popularization and application of the liftable clothes rod device and the wardrobe with the liftable clothes rod device.

[0012] In one embodiment, the lever transmission assembly includes a central slide rail vertically disposed in the middle of the housing, a first transmission lever and a second transmission lever located on both sides of the central slide rail. A slider is disposed on the central slide rail, and the slider has a pin portion. The middle parts of the first transmission lever and the second transmission lever are respectively rotatably disposed on both sides of the central slide rail through a first rotating shaft assembly and a second rotating shaft assembly. One end of the first transmission lever and the second transmission lever overlaps crosswise, and a waist-shaped hole is respectively provided. The pin portion penetrates through the two waist-shaped holes and is locked, and the pin portion can slide in the two waist-shaped holes; the other ends of the first transmission lever and the second transmission lever are respectively in transmission connection with a link assembly.

[0013] When the first link assembly on one side is driven by the driving assembly, the first transmission lever and the second transmission lever in the lever transmission assembly rotate synchronously in opposite directions around the first rotating shaft assembly and the second rotating shaft assembly respectively under the limitation of the central slide rail, the slider and the waist-shaped hole, so that the first link assembly and the second link assembly move synchronously, driving the swing rod assemblies on both sides to rotate and swing synchronously, realizing the lifting of the clothes hanger assembly. Therefore, there is no need to set two driving motors to drive the swing rods on both sides. The lever transmission assembly in this application has a simple structure, is firm and durable, and can achieve stable synchronization of the swing rod assemblies on both sides.

[0014] In one embodiment, the link assembly includes a first rocker, a second rocker, and a parallel link disposed between the first rocker and the second rocker; one end of the first rocker is butt-assembled with the swing rod assembly and is hinged to the third rotating shaft assembly, and the other end is hinged to one end of the parallel link; one end of the second rocker is hinged to the fourth rotating shaft assembly, and the other end of the second rocker is hinged to the other end of the parallel link. The parallel link is in transmission connection with the lever transmission assembly, and the driving assembly is in transmission connection with the parallel link of at least one link assembly.

[0015] The first rocker, the second rocker, and the parallel link form a parallel link device, which enables the parallel link to move up and down while maintaining a horizontal state, thereby driving the rotation of the first rocker and the second rocker, converting the lifting motion of the motor in the driving assembly into the rotational motion of the rocker, so as to realize the first rocker and the second rocker rotating and extending at a certain angle and lowering or retracting and rising. The structure of the link assembly is also stable and reliable, and there is no need to set transmission parts such as a gearbox, reducing the faults caused by the wear of the gearbox.

[0016] In one embodiment, the distance from the hinge point of the first rocker and the parallel link to the third rotating shaft assembly is equal to the distance from the hinge point of the second rocker and the parallel link to the fourth rotating shaft assembly. This ensures that the parallel link can maintain a horizontal state when moving up and down under the drive of the driving assembly, facilitating the transmission connection with the lever transmission assembly in a simple manner.

[0017] In one embodiment, the first rocker includes a first end, a second end, and a connecting portion connecting the first end and the second end. The extending directions of the first end and the second end are perpendicular to each other. The first end is butt-assembled with the swing rod assembly, the second end is hinged to one end of the parallel link, and the connecting portion is hinged to the third rotating shaft assembly.

[0018] The extending directions of the first end and the second end of the first rocker are perpendicular to each other, ensuring that the swing angle of the swing rod assembly butt-assembled with it is large enough, basically reaching 90 degrees, so as to realize a greater height and higher efficiency of the up and down lifting of the clothes hanger assembly.

[0019] In one embodiment, a square tunnel chute is provided in the parallel link. The square tunnel chute extends along the length direction of the parallel link, and its cross-section is a flat rectangle. Cylindrical slide rods are respectively provided at the other ends of the first transmission lever and the second transmission lever. The cylindrical slide rods are inserted into the square tunnel chute and can freely slide in the width direction and the length direction of the square tunnel chute.

[0020] The parallel links, the first transmission lever, and the second transmission lever in the two link assemblies are drivably connected through the docking and assembly of the square tunnel chute and the cylindrical slide rods. The cross-section of the square tunnel chute is a flat rectangle. Thus, when the first transmission lever and the second transmission lever move, the cylindrical slide rods can freely slide in the width direction and the length direction of the square tunnel chute. Such a drivable connection structure is simple, with stronger reliability and stability, which is beneficial to increasing the maximum number of times of use.

[0021] In one embodiment, the drive assembly includes a drive part housing and an electric push rod provided in the drive part housing. The drive assembly is arranged below one of the link assemblies, and the top end of the electric push rod is hinged to one of the link assemblies. The drive assembly is only hinged to one link assembly, and only by driving one link assembly can the swing rod assemblies on both sides be driven. Therefore, the structure of the drive assembly is also simplified, with a smaller volume and less occupation of the wardrobe space.

[0022] In one embodiment, a drive mounting seat is provided in the drive part housing, and the bottom end of the electric push rod is hinged to the drive mounting seat. When the electric push rod pushes the link assembly to move, since its bottom end is hinged to the drive mounting seat, it is allowed to swing at a certain angle, which is beneficial to increasing stability.

[0023] In one embodiment, the swing rod assembly includes a swing rod and third rotating shaft assemblies and L-shaped elbows located at both ends of the swing rod. The third rotating shaft assemblies are docked and assembled with one end of the first rocker, and the L-shaped elbows are docked and assembled with the clothes hanging rod assembly. The swing rod assembly and the clothes hanging rod assembly are detachably docked, which is convenient for replacement. The fifth rotating shaft assembly can be installed on the side panel of the wardrobe, and the installation is more convenient.

[0024] In one embodiment, the housing includes an intermediate housing located in the middle and side housings located on both sides. The side housings vertically extend out from both sides of the intermediate housing. The lever transmission assembly is arranged in the intermediate housing, and the two link assemblies are respectively arranged in the side housings on both sides. The housing is U-shaped, which can be more closely attached to the back panel and side panels of the wardrobe for installation, correspondingly accommodating the lever transmission assembly and the two link assemblies, providing comprehensive protection for the transmission mechanism, reducing failures, and being more beautiful and small in volume.

[0045] In order to balance the rotational support force of the two swing rods in a common liftable clothes rod device, drive boxes need to be provided on both sides, and a drive motor, a transmission mechanism, and an encoder need to be provided in each drive box to keep the rotation of the two swing rods synchronized. Embedded wire grooves need to be opened at the positions of the cabinet corresponding to the two drive boxes to lead the motor leads to the back and connect them to the controller. This results in a relatively large thickness of the drive box, making it not thin and light enough, protruding significantly inside the cabinet, occupying more internal space of the wardrobe, increasing the installation difficulty, and raising the cost.

[0046] An embodiment of the present application provides a liftable clothes hanger device, which includes a housing, a lever transmission assembly disposed in the middle of the housing, two link assemblies respectively disposed on both sides of the housing and respectively drivingly connected to the lever transmission assembly, a driving assembly for driving at least one of the link assemblies to move, two swing rod assemblies respectively assembled at the ends of the two link assemblies, and a clothes hanger assembly disposed between the two swing rod assemblies; the driving assembly is drivingly connected to at least one of the link assemblies to drive at least one of the link assemblies to move, and the lever transmission assembly makes the two link assemblies move synchronously through the driving connection with the two link assemblies. The two link assemblies respectively drive the two swing rod assemblies to rotate and swing in a plane parallel to the side surface of the housing, driving the clothes hanger assembly to lift and lower.

[0047] By drivingly connecting the lever transmission assembly to the two link assemblies on both sides respectively, and respectively docking and assembling the two link assemblies with the swing rod assemblies, only a driving assembly needs to be provided on one side, and by driving the link to drive one of the link assemblies to move, the two swing rod assemblies can be synchronously driven to rotate and swing through the lever transmission assembly, so that the clothes hanger assembly installed on the two swing rod assemblies rises or falls, facilitating the user to hang clothes and raise the clothes. It is not necessary to directly arrange both the driving assembly and the transmission mechanism in the driving box, nor is it necessary to separately provide driving motors for the swing rods on both sides, reducing the occupation of the internal space of the wardrobe by the driving box and reducing the cost.

[0048] Please refer to Figures 2 to 4 As shown, the liftable clothes hanger device includes: a housing 10, a lever transmission assembly 20 disposed in the middle of the housing 10, two link assemblies 30 respectively disposed on both sides of the housing 10 and respectively drivingly connected to the lever transmission assembly 20, a driving assembly 40 for driving at least one of the link assemblies 30 to move, two swing rod assemblies 50 respectively assembled at the ends of the two link assemblies 40, and a clothes hanger assembly 60 disposed between the two swing rod assemblies 50. If the driving assembly 40 is drivingly connected to at least one of the link assemblies 30 to drive at least one of the link assemblies 30 to move, the lever transmission assembly 20 makes the two link assemblies 30 move synchronously through the driving connection with the two link assemblies 30. The two link assemblies 30 respectively drive the two swing rod assemblies 50 to rotate and swing in a plane parallel to the side surface of the housing, so as to drive the clothes hanger assembly 60 to lift and lower. Figure 3 As shown, the maximum swing angle θ of the two swing rod assemblies 50 can be adjusted and set as needed, and can be limited by setting limit members, etc.

[0049] The liftable clothes hanger device of the present application is provided with a lever transmission assembly 20 in the middle of the housing 10, which is respectively connected to two link assemblies 30 arranged on both sides of the housing. The two link assemblies 30 on both sides are respectively assembled with the swing rod assemblies 50. The driving assembly 40 does not directly connect to drive the swing rod assemblies 50, but drives the swing rod assemblies 50 through the link assemblies 40. Therefore, it is not necessary to directly arrange both the driving assembly and the transmission mechanism in the driving box. And the driving assembly only needs to drive at least one of the link assemblies to move, and then can synchronously drive the two swing rod assemblies to rotate and swing through the lever transmission assembly, so that the clothes hanger assemblies installed on the two swing rod assemblies can be raised or lowered, which is convenient for users to hang clothes and raise the clothes. It is also not necessary to separately provide driving motors for the swing rod assemblies on both sides, reducing the occupation of the internal space of the wardrobe by the driving box; there is no need to set an encoder, reducing the cost. At the same time, only the lead wire of the driving motor needs to be arranged on one side, which is more convenient for installation and is more conducive to the popularization and application of the liftable clothes hanger device and the wardrobe with the liftable clothes hanger device.

[0050] The housing 10 is a U-shaped housing, including a middle housing in the middle and side housings on both sides. The side housings extend vertically from both sides of the middle housing. The lever transmission assembly 20 is arranged in the middle housing, and the two link assemblies 30 are respectively arranged in the side housings on both sides. When installing the liftable clothes hanger device into the wardrobe, the middle housing is closely installed against the back panel of the wardrobe, and the side housings on both sides are closely installed against the side panels of the wardrobe. The driving assembly is installed below one of the side housings to drive the link assembly 30 on that side, drive the lever transmission assembly 20 in the middle housing, and make the link assembly 30 on the other side move synchronously. The swing rod assemblies 50 and the clothes hanger assemblies 60 swing and lift in the cabinet of the wardrobe.

[0051] In an embodiment, the housing 10 includes a U-shaped fixing base 110, a front cover 120 and two side covers 130. The front cover 120 covers the front of the U-shaped fixing base 110 to form the middle housing and accommodate the lever transmission assembly 20. The two side covers 130 respectively cover the two inner sides of the U-shaped fixing base 110 to form the two side housings on both sides of the middle housing and correspondingly accommodate the two link assemblies 30.

[0052] The U-shaped housing 10 can correspondingly accommodate the lever transmission assembly 20 and the two link assemblies 30, be more firmly installed in the wardrobe, comprehensively protect the transmission mechanism, reduce failures, and be more beautiful. And it can save space to the greatest extent and reduce the occupation of the internal space of the wardrobe.

[0053] Please refer to Figure 5The lever transmission assembly 20 includes a central slide rail 210 vertically disposed in the middle of the housing 10, and a first transmission lever 220 and a second transmission lever 230 located on both sides of the central slide rail 210. A slider 240 is disposed on the central slide rail 210. The slider 240 has a pin portion 241. The middle portions of the first transmission lever 220 and the second transmission lever 230 are rotatably fixed to both sides of the central slide rail 210 through a first rotating shaft assembly and a second rotating shaft assembly respectively. One ends of the first transmission lever 220 and the second transmission lever 230 overlap crosswise, and are respectively provided with an oblong hole 222, 232. The pin portion 241 penetrates through the two oblong holes 222, 232 and is locked. The pin portion 241 can slide within the two oblong holes 222, 232. The other ends of the first transmission lever 220 and the second transmission lever 230 are respectively in transmission connection with a link assembly 30.

[0054] In one embodiment, the central slide rail 210 is disposed at the middle position on the front surface of the U-shaped fixing base 101. A first rotating shaft 111 and a second rotating shaft 112 are respectively disposed on both sides of the central slide rail 210 on the front surface of the U-shaped fixing base 110. A vertically extending chute 211 is disposed on the central slide rail 210. The pin portion 241 of the slider 240 penetrates through the two oblong holes 222, 232 and the chute 211 and then is locked. First rotating shaft holes 221 and 231 are disposed in the middle of the first transmission lever 220 and the second transmission lever 230. The first rotating shaft 111 matches with the first rotating shaft hole 221 to form a first rotating shaft assembly; the second rotating shaft 112 and the second rotating shaft hole 231 form a second rotating shaft assembly 231, so that the first transmission lever 220 and the second transmission lever 230 can rotate around the first rotating shaft assembly and the second rotating shaft assembly respectively.

[0055] One ends of the first transmission lever 220 and the second transmission lever 230 are respectively provided with a cylindrical slide rod 233. The cylindrical slide rod 233 is used for inserting into the corresponding link assembly 30 to form a transmission with the corresponding link assembly 30. When the slider 240 slides, the pin portion 241 can drive the first transmission lever 220 and the second transmission lever 230 to rotate synchronously in opposite directions around the first rotating shaft assembly and the second rotating shaft assembly respectively, driving the cylindrical slide rods 233 at the other ends of the first transmission lever 220 and the second transmission lever 230 to move up and down, thereby driving the corresponding link assembly 30 to move up and down.

[0056] Please refer to Figures 6 to 8The liftable clothes rod device of the present application includes two symmetrically arranged connecting rod assemblies 30, each connecting rod assembly 30 includes: a first rocking arm 310 and a second rocking arm 320, and a parallel connecting rod 330 arranged between the first rocking arm 310 and the second rocking arm 320; one end of the first rocking arm 310 is docked and assembled with the rocker assembly 50 and is hinged to the third rotating shaft assembly, and the other end is hinged to one end of the parallel connecting rod 330; one end of the second rocking arm 320 is hinged to the fourth rotating shaft assembly, and the other end of the second rocking arm 320 is hinged to the other end of the parallel connecting rod 330, the parallel connecting rod 330 is transmission-connected to the lever transmission assembly 20, and the driving assembly 40 is transmission-connected to the parallel connecting rod 330 of at least one connecting rod assembly 30.

[0057] In one embodiment, a rotating shaft sleeve 321 is fixed to one end of the second rocker 320, and the inner hole of the rotating shaft sleeve 321 is in clearance with the fourth rotating shaft 113 on an inner side surface of the U-shaped fixing seat 110, and can rotate smoothly, forming a fourth rotating shaft assembly. One end of the first rocker 310 is docked and assembled with the rocker assembly 50, and is hinged to the third rotating shaft assembly through the rocker assembly 50, and the other end is fixed to the first U-shaped hinge seat 340, and one end of the parallel connecting rod 330 is hinged to the hinge hole of the first U-shaped hinge seat 340 through a pin. A second U-shaped hinge seat 350 is provided at the lower part of the parallel connecting rod 330, and the second U-shaped hinge seat 350 can be hinged to the electric push rod 410 extended from the driving assembly 40 through a pin, so as to realize the transmission connection between the driving assembly 40 and the connecting rod assembly 30, and the driving assembly 40 drives the connecting rod assembly 30 to move.

[0058] The first rocker 310, the second rocker 320 and the parallel link 330 form a parallel link device, so that the parallel link 330 can be lifted up and down in a horizontal state when driven by the driving assembly 40, and can drive the first rocker and the second rocker to rotate synchronously. The telescopic motion of the electric push rod 410 in the driving assembly 40 is converted into the rotational motion of the rocker, so that the first rocker 310 and the second rocker 320 can rotate at a certain angle, and the swing arm assembly 50 and the clothes hanging rod assembly 60 can be extended and lowered or retracted and raised.

[0059] like Figure 8As shown, when the extension length of the electric push rod 410 of the driving component 40 is H2, the rising height of the parallel link 330 while maintaining a horizontal state is H3, and the end of the first rocker 310 that docks with the swing rod assembly 50 rotates counterclockwise by an angle α around the third rotating shaft assembly. It rotates synchronously with the swing rod assembly 50 that is assembled with the first rocker 310 by an angle α, causing the clothes hanger rod assembly 60 to extend and lower, so that users can conveniently hang clothes on the clothes hanger rod assembly 60. After hanging the clothes, the electric push rod 410 in the driving component 40 can be controlled to contract, causing the parallel link 330 to descend while maintaining a horizontal state. The end of the first rocker that docks with the swing rod assembly rotates clockwise around the third rotating shaft assembly, and swings synchronously with the swing rod assembly 50 that is assembled with the first rocker 310 in a clockwise direction to retract and raise the clothes hanger rod assembly 60. In one embodiment, the maximum angle of rotation of the end of the first rocker 310 that docks with the swing rod assembly 50 around the third rotating shaft assembly is set to 90 degrees. That is, when the angle α is zero, the clothes hanger rod assembly 60 retracts into the wardrobe and is at the highest point; when the angle α is 90 degrees, the clothes hanger rod assembly 60 extends and is at the lowest point.

[0060] The structure of the link assembly 30 is also stable and reliable, without the need to set transmission parts such as a gearbox, reducing the failures caused by the wear of the gearbox.

[0061] Optionally, the distance from the hinge point of the first rocker 310 and the parallel link 330 to the third rotating shaft assembly is equal to the distance from the hinge point of the second rocker 320 and the parallel link 330 to the fourth rotating shaft assembly. As Figure 7 shown in the figure, a1 = a2. Thus, it is ensured that the parallel link 330 can maintain a horizontal state when moving up and down under the drive of the driving component 40, facilitating the transmission connection with the lever transmission component 20 in a simple manner.

[0062] The first rocker 310 may include a first end and a second end connected to each other at a certain angle, and a connecting portion (not labeled) connecting the first end and the second end. The first end is assembled with the swing rod assembly 50 in a docking manner, the second end is hinged to one end of the parallel link 330, and the connecting portion is hinged to the third rotating shaft assembly. The connecting portion forms a certain angle with the extending direction of the swing rod assembly 50, and when the first rocker 310 rotates around the third rotating shaft assembly, it drives the swing rod assembly 50 to swing.

[0063] Preferably, the extending directions of the first end and the second end are perpendicular to each other, ensuring that the swing angle of the swing rod assembly 50 assembled with it in a docking manner is large enough, basically reaching 90 degrees or even larger, so as to achieve a greater height and higher efficiency for the up and down lifting of the clothes hanger rod assembly 60. Please refer to Figures 9 to 10, in one embodiment, a square tunnel chute 331 is provided in the parallel link 330. The square tunnel chute 331 extends along the length direction of the parallel link 330, and its cross-section is a flat rectangle. Cylindrical slide rods 233 are respectively provided at the other ends of the first transmission lever 220 and the second transmission lever 230. The cylindrical slide rods 233 are respectively inserted into the corresponding square tunnel chutes 331 and can freely slide in the width direction and the length direction of the square tunnel chutes 331.

[0064] The parallel link 330, the first transmission lever 220, and the second transmission lever 230 in the two link assemblies are in transmission connection through the docking assembly of the square tunnel chute 331 and the cylindrical slide rod 233. The cross-section of the square tunnel chute 331 is a flat rectangle. Thus, when the first transmission lever 220 and the second transmission lever 230 move, the cylindrical slide rod 233 can freely slide in the width direction and the length direction of the square tunnel chute 331. Such a transmission connection structure is simple, has stronger reliability and stability, and is beneficial to increasing the maximum number of usable times.
