Description

Technical Field

[0001] This application relates to shoe cabinets, and more particularly to an electric shoe changing device and shoe cabinet. Background Technology

[0002] A shoe cabinet is an essential tool for storing shoes in any household. Without one, shoes left haphazardly placed at the entrance to the living room can seriously affect the cleanliness and hygiene of the space. Shoe cabinets are typically installed at the entrance of the living room. To improve the quality of life, some families also install electric shoe-changing platforms. When entering the house, users simply place their shoes on the extended platform, and the electric telescopic mechanism automatically retracts the platform and the shoes inside the cabinet, eliminating the need for manual shoving and making the process more convenient.

[0003] These types of shoe changing boards typically require sliding rails installed on the bottom or sides to ensure stability during extension and retraction, preventing lateral swaying.

[0027] Example 1: This embodiment provides an electric shoe changing device, including: a fixed base 100, a movable plate 200, a cross telescopic arm 300, and a power unit 400.

[0028] like Figure 1-7As shown, the movable plate 200 is disposed on one side of the fixed base 100 and can move relative to the fixed base 100 to move away from or towards the fixed base 100. The cross telescopic arm 300 has a first connecting part 310 and a second connecting part 320. The first connecting part 310 of the cross telescopic arm 300 is movably connected to the fixed base 100, and the second connecting part 320 of the cross telescopic arm 300 is movably connected to the movable plate 200. The power unit 400 is connected to the cross telescopic arm 300 and can drive the cross telescopic arm 300 to move; causing the movable plate 200 to move significantly away from or towards the fixed base 100, realizing the extension and retraction of the movable plate 200. The second connecting part 320 of the cross telescopic arm 300 has a stable bearing function for the movable plate 200, so that the electric shoe changing device can ensure the smooth movement of the movable plate without the need for a sliding guide rail. The electric shoe changing device is simpler and more convenient to install and use.

[0029] In one embodiment, such as Figure 5-7 As shown, the cross telescopic arm 300 includes a first rod 330 and a second rod 340 of the same length. The first rod 330 and the second rod 340 intersect each other and are rotatably connected at the intersection. The first connecting part 310 includes a first end 350 of the first rod 330 and a third end 370 of the second rod 340. The second connecting part 320 includes a second end 360 of the first rod 330 and a fourth end 380 of the second rod 340. The first end 350 of the first rod 330 is movably connected to the fixed base 100, and the second end 360 of the first rod 330 is movably connected to the movable plate 200; the third end 370 of the second rod 340 is movably connected to the fixed base 100, and the fourth end 380 of the second rod 340 is movably connected to the movable plate 200.

[0030] A power unit 400 is mounted on a fixed base 100 and connected to the first end 350 of the first rod 330. The power unit 400 can drive the first end 350 of the first rod 330 to move closer to or further away from the third end 370 of the second rod 340 along a first direction a, causing the cross-telescopic arm 300 to move as a whole. This, in turn, changes the relative position of the first connecting part 310 and the second connecting part 320, causing the movable plate 200 to move closer to or further away from the fixed base 100 along a second direction b, ultimately extending and retracting the movable plate 200. Simultaneously, the combined action of the second end 360 of the first rod 330 and the fourth end 380 of the second rod 340 on the movable plate 200 ensures the directional stability of the movable plate 200 during movement, preventing lateral swaying and improving the user experience of the electric shoe-changing device. In this embodiment, as... Figure 1 As shown, the power unit 400 is horizontally mounted on the fixed base 100, which optimizes the height space of the shoe changing device and facilitates installation. Of course, in other embodiments, such as... Figure 10As shown, the power unit 400 can also be mounted longitudinally on the fixed base 100, making the shoe changing device thinner, optimizing the horizontal space, meeting different installation needs, and improving the user experience of the shoe changing device.

[0031] It should be noted that the power unit 400 can also be located at the movable plate 200, the cross telescopic arm 300, or other positions; the power output point of the power unit 400 can also be at the second end 360, the third end 370, the fourth end 380, or other positions on the cross telescopic arm 300. As long as the power unit 400 can drive the cross telescopic arm 300 to move, causing a change in the relative position of the first connecting part 310 and the second connecting part 320, it can drive the movable plate 200 away from or towards the fixed base 100, realizing the extension and retraction of the movable plate 200, and achieving a good driving effect.

[0032] In one embodiment, the middle portion of the first rod 330 intersects and is rotatably connected to the middle portion of the second rod 340. When the cross telescopic arm 300 moves, the forces on the first connecting portion 310 and the second connecting portion 320 are more balanced, improving the stability and smoothness of the movement of the movable plate 200 and optimizing the user experience of the electric shoe changing device.

[0033] In one embodiment, such as Figure 6-8 As shown, a second sliding groove 210 is provided on the movable plate 200 extending along the first direction a. The second end 360 of the first rod 330 is rotatably connected to a first hinge block 361, and the fourth end 380 of the second rod 340 is rotatably connected to a second sliding block 381. The first hinge block 361 is fixedly installed within the second sliding groove 210, and the second sliding block 381 is slidably installed within the second sliding groove 210. When the power device 400 drives the cross telescopic arm 300 to move, the fourth end 380 of the second rod 340 will move closer to or further away from the second end 360 of the first rod 330 through the sliding of the second sliding block 381, thereby driving the movement of the movable plate 200.

[0034] As a preferred embodiment, the first rod 330 and the second rod 340 are of the same length, and the first direction 'a' is the direction of the straight line connecting the first end 350 of the first rod 330 and the third end 370 of the second rod 340. The second sliding groove 210 is a straight groove extending along the first direction 'a' on the movable plate 200. When the power unit 400 drives the cross telescopic arm 300 to move, the line connecting the first end 350 and the third end 370 is always parallel to the line connecting the fourth end 380 and the second end 360, so that the second direction 'b' of the movement of the movable plate 200 is always perpendicular to the first direction 'a'. In this way, the movement direction of the movable plate 200 is stable and the shoe-changing device is more convenient to use.

[0035] In one embodiment, multiple sets of second sliding grooves 210 are arranged in parallel on the movable plate 200. The first hinge block 361 and the second sliding block 381 are located within the same second sliding groove 210, ensuring that the line connecting the first end 350 and the third end 370 is always parallel to the line connecting the fourth end 380 and the second end 360, thus guaranteeing the stability of the movable plate 200's movement direction. By selectively installing the first hinge block 361 and the second sliding block 381 into other second sliding grooves 210, the travel distance of the movable plate 200 can be adjusted to meet the needs of different usage scenarios. Simultaneously, the arrangement of multiple sets of second sliding grooves 210 also reduces the weight of the movable plate 200, lowers the resistance to its movement, and improves the smoothness of its movement.

[0036] In one embodiment, the cross telescopic arm 300 is formed by connecting multiple sets of cross-arranged rods sequentially along the second direction b, so as to increase the travel of the movable plate 200 and meet the user's needs.

[0037] In one embodiment, multiple sets of cross telescopic arms 300 can be provided, evenly distributed along the first direction a between the fixed base 100 and the movable plate 200. Multiple sets of cross telescopic arms 300 work together to act on and support the movable plate 200, so as to ensure the stability of the movement of the movable plate 200.

[0038] In one embodiment, such as Figure 8 As shown, rollers 500 are fixedly installed at the bottom of the movable plate 200. The rollers 500 can reduce the friction between the movable plate 200 and the bottom of the shoe cabinet or the ground, making the extension and retraction of the movable plate 200 smoother. At the same time, the rollers 500 can also reduce the noise of the movable plate 200 moving and improve the user experience of the shoe changing device.

[0039] In one embodiment, the movable plate 200 is tilted from the side closer to the fixed base 100 to the side farther away from the fixed base 100, so that the side of the movable plate 200 closer to the fixed base 100 is higher than the side farther away from the fixed base 100, and a receiving space 220 is provided at the bottom of the side of the movable plate 200 closer to the fixed base 100. When the movable plate 200 is retracted, the receiving space 220 can accommodate the power unit 400 and part of the fixed base 100, making the overall structure of the electric shoe changing device more compact and easier to install and use. At the same time, the movable plate 200 can cover the power unit 400 when retracted, thereby improving the aesthetics and safety of the electric shoe changing device.

[0040] In one embodiment, such as Figure 6 , 9As shown, the power unit 400 includes a motor 410, a transmission belt assembly 421, and a connector 430. The transmission belt assembly 421 extends along a first direction a and is mounted on the fixed base 100. The connector 430 is mounted on the transmission belt of the transmission belt assembly 421. The first end 350 of the first rod 330 is rotatably connected to the connector 430. The motor 410 drives the transmission belt assembly 421 to move, thereby moving the connector 430 along the first direction a. This causes the first end 350 of the first rod 330 to move closer to or further away from the third end 370 of the second rod 340 along the first direction a, thereby driving the cross telescopic arm 300 to move and causing the movable plate 200 to extend and retract, achieving a good driving effect.

[0041] In one embodiment, such as Figure 11-15 As shown, the power unit 400 includes a motor 410, a transmission rack 422, and a connecting member 430. The transmission rack 422 is slidably mounted on the fixed base 100 along a first direction a, and the connecting member 430 is mounted on the transmission rack 422. The motor 410 drives the transmission rack 422 to slide along the first direction a on the fixed base 100. The transmission rack 422 is used to drive the connecting member 430 to move along the first direction a, so that the first end 350 of the first rod 330 moves closer to or further away from the third end 370 of the second rod 340 along the first direction a, thereby driving the movement of the cross telescopic arm 300, causing the movable plate 200 to extend and retract, achieving a good driving effect.

[0042] In one embodiment, such as Figure 16-17 As shown, the power unit 400 includes a motor 410, a transmission screw 423, and a connecting member 430. The transmission screw 423 extends along a first direction a and is mounted on the fixed base 100, and the connecting member 430 is mounted on the transmission screw 423. The motor 410 drives the transmission screw 423 to rotate, thereby causing the connecting member 430 to move along the first direction a, so that the first end 350 of the first member 330 moves closer to or further away from the third end 370 of the second member 340 along the first direction a. This drives the movement of the cross telescopic arm 300, causing the movable plate 200 to extend and retract, achieving a good driving effect.

[0043] In one embodiment, such as Figure 18-19As shown, a first sliding groove 110 is provided on the fixed base 100 along the first direction a. A connecting member 430 is rotatably connected to the first end 350 of the first rod 330. The connecting member 430 is installed in the first sliding groove 110 and can slide within the first sliding groove 110. The second end 360 of the first rod 330 is rotatably connected to the movable plate 200; the fourth end 380 of the second rod 340 is rotatably connected to the movable plate 200. A power device 400 is disposed on the fixed base 100 and is rotatably connected to the third end 370 of the second rod 340. The power device 400 drives the third end 370 of the second rod 340 to rotate, causing the first end 350 of the first rod 330 to move closer to or further away from the third end 370 of the second rod 340 along the first direction a. This drives the movement of the cross telescopic arm 300, causing the movable plate 200 to extend and retract, achieving a good driving effect. Of course, in other embodiments, the power device 400 can also be configured with other structures, such as an electric push rod. In general, any drive structure that can drive the cross telescopic arm 300 to move, thereby changing the relative position of the first connecting part 310 and the second connecting part 320, can be used as the power device 400 of this application.

[0044] In one embodiment, a guide ramp 600 is provided on the side of the movable plate 200 away from the fixed base 100. The guide ramp 600 not only makes it convenient for users to kick their shoes directly onto the movable plate 200, but also prevents debris from entering the bottom of the movable plate 200 and creating a dead corner for hygiene, thus improving the user experience of the electric shoe changing device.

[0045] In one embodiment, such as Figure 20-22 As shown in Figures 26-30, to further improve the load-bearing stability and smooth movement of the movable plate 200, the cross telescopic arms 300 adopt a multi-group parallel design. At least two groups of cross telescopic arms 300 are arranged at intervals along the first direction a on the fixed base 100 between a movable plate 200 and a fixed base 100, and each group of cross telescopic arms 300 includes a first member 330 and a second member 340.

[0046] Specifically, the first connecting portion 310 includes: a first end 350 of the first rod 330 and a third end 370 of the second rod 340. The second connecting portion 320 is the second end 360 of the first rod 330. The second end 360 of the first rod 330 is rotatably connected to the movable plate 200. The third end 370 of the second rod 340 is rotatably connected to the fixed base 100, and the fourth end 380 of the second rod 340 is rotatably connected to the first rod 330, with its connection position located between the first end 350 and the second end 360.

[0047] The main body of the power unit 400 is fixedly mounted on the fixed base 100. The power output shaft of the power unit 400 is synchronously connected to the first end 350 of the first rod 330 in each group of cross telescopic arms 300, thereby driving the first end 350 of the first rod 330 in all cross telescopic arms 300 to simultaneously approach or move away from the third end 370 of the second rod 340 in the same group of cross telescopic arms 300 along the first direction a. When multiple groups of cross telescopic arms 300 operate in coordination, the second end 360 of each group of first rods 330 applies a pushing or pulling force to different positions of the same movable plate 200, driving the movable plate 200 to move stably along the second direction b. Through the parallel layout of multiple groups of cross telescopic arms 300, and in conjunction with the hinge structure between the second connecting part 320 in each group of cross telescopic arms 300 and different positions on the same movable plate 200, multi-point coordinated support is formed on the movable plate 200, improving the stability of the movable plate 200 during movement.

[0048] In one embodiment, the fourth end 380 of the second rod 340 is connected to the middle of the first rod 330, making the supporting force of the second rod 340 on the first rod 330 more uniform, and at the same time, making the intersection angle between the second rod 340 and the first rod 330 more reasonable. With this configuration, the relative rotation between the first rod 330 and the second rod 340 is smoother during the extension and retraction of the cross telescopic arm 300, reducing mechanical wear and further extending the service life and operational smoothness of the cross telescopic arm 300.

[0049] In one embodiment, such as Figure 23-25 As shown, at least two sets of cross telescopic arms 300 are provided, which are mounted on the fixed base 100 along the first direction a. Each set of cross telescopic arms 300 consists of a first member 330, a second member 340, a third member 710, and a fourth member 720, forming a multi-level linkage cross structure.

[0050] Specifically, the first member 330 and the second member 340 are rotatably connected to form a basic cross unit. The fourth end 380 of the second member 340 is rotatably connected to the first member 330, and this connection point is located between the first end 350 and the second end 360 of the first member 330. The fifth end 711 of the third member 710 is rotatably connected to the second end 360 of the first member 330, realizing linkage with the first member 330. The seventh end 721 of the fourth member 720 is rotatably connected to the fourth end 380 of the second member 340, forming linkage with the second member 340. The first connecting part 310 is composed of the first end 350 of the first member 330 and the third end 370 of the second member 340. The second connecting part 320 is the eighth end 722 of the fourth member 720. The eighth end 722 of the fourth member 720 is rotatably connected to the movable plate 200 and is the core output point that drives the movement of the movable plate 200. The sixth end 712 of the third member 710 is rotatably connected to the fourth member 720 and is located between the seventh end 721 and the eighth end 722 of the fourth member 720 to support the fourth member 720. The third end 370 of the second member 340 is rotatably connected to the fixed base 100.

[0051] The main body of the power unit 400 is fixedly mounted on the fixed base 100. The power output shaft of the power unit 400 is synchronously connected to the first end 350 of the first rod 330 in each group of cross telescopic arms 300. The power unit 400 can synchronously drive the first end 350 of the first rod 330 in all cross telescopic arms 300 to simultaneously approach or move away from the third end 370 of the second rod 340 in the same group of cross telescopic arms 300 along the first direction a, and drive the third rod 710 through the first rod 330, and drive the fourth rod 720 through the second rod 340. When multiple groups of cross telescopic arms 300 work together to drive the same movable plate 200, since the second connecting part 320 in each group of cross telescopic arms 300 is hinged to different positions of the movable plate 200, the second connecting part 320 in each group of cross telescopic arms 300 forms a pushing or pulling force at different positions of the movable plate 200, thereby driving the movable plate 200 to move stably along the second direction b.

[0052] Compared to the dual-bar cross telescopic arm 300, the four-bar multi-stage linkage amplifies the short-distance movement of the first bar 330 into a long-distance displacement of the eighth end 722 of the fourth bar 720 by superimposing the lever arms. This can significantly extend the travel of the movable plate 200 and improve the user experience of the electric shoe changing board.

[0053] In one embodiment, only two sets of cross telescopic arms 300 are provided, and they are symmetrically arranged about the central axis of the fixed base 100 in the first direction a. The second connecting parts 320 of the two sets of telescopic arms are respectively connected to the left and right sides of the movable plate 200 in the first direction a, forming a double-sided support structure. By providing balanced support to the movable plate 200 from both sides, the anti-eccentric load capacity of the movable plate 200 is enhanced. At the same time, the double-sided connection makes the force center of the movable plate 200 more closely match the movement trajectory, ensuring that the movable plate 200 will not deviate to the left or right when moving along the second direction b, thus improving the linearity and stability of the movement. At this time, the power device 400 needs to synchronously drive the first end 350 of the first rod 330 in the two sets of cross telescopic arms 300 to move in opposite directions in order to drive the movable plate 200 to move stably along the second direction b.

[0054] In one embodiment, such as Figure 20-26 As shown, the power unit 400 includes a motor 410, a transmission belt assembly 421, a first connector 431, and a second connector 432. The transmission belt assembly 421 extends along a first direction a and is mounted on the fixed base 100. The second connector 432 and the first connector 431 are both located on the lower side of the transmission belt assembly 421, so that the two sets of cross telescopic arms 300 are located on the same plane. The first connecting portions 310 of the two sets of cross telescopic arms 300 are rotatably connected to the first connector 431 and the second connector 432, respectively. The motor 410 drives the transmission belt assembly 421 to move, synchronously driving the first ends 350 of the first rods 330 in the two sets of cross telescopic arms 300 to move in opposite directions at the same moving speed, thereby driving the movable plate 200 to move stably along the second direction b.

[0055] In one embodiment, such as Figure 27-30 As shown, the power unit 400 includes: a motor 410, a first transmission rack 424, a second transmission rack 425, a first connecting member 431, and a second connecting member 432. A first sliding groove 120 and a second sliding groove 130 are provided on the fixed base 100 extending along a first direction a; the first transmission rack 424 is slidably mounted in the first sliding groove 120, and the second transmission rack 425 is slidably mounted in the second sliding groove 130. The first connecting member 431 is mounted on the first transmission rack 424; the second connecting member 432 is mounted on the second transmission rack 425. The first connecting portions 310 of the two sets of cross telescopic arms 300 are rotatably connected to the first connecting member 431 and the second connecting member 432, respectively.

[0056] An output gear is fixedly mounted on the power output shaft of the motor 410. The output gear is located between the first transmission rack 424 and the second transmission rack 425, and meshes with both the first and second transmission racks 424 and 425, thereby simultaneously driving the first and second transmission racks 424 and 425 to slide synchronously. Clearly, by directly meshing with the same output gear, the first and second transmission racks 424 and 425 move in opposite directions.

[0057] It should be noted that when the motor 410 is driven, the first transmission rack 424 and the second transmission rack 425 can respectively drive the first connecting member 431 and the second connecting member 432 to move along the first direction a, and make the first connecting member 431 and the second connecting member 432 approach each other or move away from each other at the same speed, thereby synchronously driving the first end 350 of the first rod 330 in the two sets of cross telescopic arms 300 to approach each other or move away from each other at the same moving speed, thereby driving the movable plate 200 to move stably in the second direction b, achieving a good driving effect.

[0058] In one embodiment, such as Figures 31-32 As shown, the power unit 400 includes: a motor 410, a forward lead screw 426, a reverse lead screw 427, a first connecting member 431, and a second connecting member 432. The forward lead screw 426 and the reverse lead screw 427 extend in a first direction a and are respectively disposed at both ends of the motor 410. The first connecting member 431 is mounted on the forward lead screw 426; the second connecting member 432 is mounted on the reverse lead screw 427. The first connecting portion 310 of the first rod 330 is rotatably connected to the first connecting member 431; the third connecting portion of the second rod 340 is rotatably connected to the second connecting member 432. The motor 410 drives the forward lead screw 426 and the reverse lead screw 427 to rotate, thereby driving the first connecting member 431 and the second connecting member 432 to move along the first direction a, so as to synchronously drive the first ends 350 of the first rods 330 of the two sets of cross telescopic arms 300 to move in opposite directions at the same moving speed, thereby driving the movable plate 200 to move stably along the second direction b, achieving a good driving effect.

[0059] Example 2: This embodiment provides a shoe cabinet, including a cabinet body with a shoe storage slot at the bottom and an electric shoe changing device as described in Embodiment 1, which is installed in the shoe storage slot; The fixed base 100 is fixed inside the shoe storage slot, and the movable plate 200 is away from or close to the fixed base 100 to extend or retract into the shoe storage slot, making it convenient for users to take and put away shoes and improving the user experience of the shoe cabinet.

[0060] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: 1) The electric shoe changing device uses a power unit 400 to drive the telescopic arm 300 to extend and retract, thereby extending and retracting the movable plate 200. The electric shoe changing device eliminates the need for sliding rails, making installation simpler and more convenient.

[0061] 2) Due to the combined action of the second end 360 of the first rod 330 and the fourth end 380 of the second rod 340 on the movable plate 200, the stability of the movable plate 200 is ensured, and the left and right swaying during the movement of the movable plate 200 is avoided, thus improving the user experience of the electric shoe changing device.

[0062] The above descriptions are merely some embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
