[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the liftable base 1 provided in the embodiment of the present application. Figure 2 The exploded schematic diagram of the liftable base 1 provided in the embodiment of the present application. The liftable base 1 provided in the embodiment of the present application for use in a clothes processing device comprises a base 10 , a lift platform 20 and a crank mechanism 30 .

[0034] The lifting platform 20 is movably mounted on the base 10. The crank mechanism 30 includes a rotating connecting shaft 31 and two connecting rod assemblies 32. The rotating connecting shaft 31 is provided with threads along its axial direction. The two connecting rod assemblies 32 are screwed to the rotating connecting shaft 31 at intervals. Each connecting rod assembly 32 is rotatably connected between the base 10 and the lifting platform 20. When the rotating connecting shaft 31 rotates, the rotating connecting shaft 31 drives the two connecting rod assemblies 32 to approach or move away from each other along the rotating connecting shaft 31, so that the connecting rod assembly 32 performs a swinging motion. When the connecting rod assembly 32 swings, it can drive the lifting platform 20 to move upward or downward relative to the base 10 along the direction of gravity. By converting the rotating motion of the rotating connecting shaft 31 into the swinging motion of the connecting rod assembly 32, and then converting the swinging motion of the connecting rod assembly 32 into the motion of the lifting platform 20 driving the clothing processing device to move upward or downward relative to the base 10, it is convenient to adjust the height position of the clothing processing device installed on the liftable base 1 to adapt to the use of the clothing processing device by different user groups.

[0035] See also Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the connection structure between the base 10 and the crank mechanism 30 on one side provided in an embodiment of the present application. Figure 4 This is a schematic diagram of the connection structure on the other side between the base 10 and the crank mechanism 30 provided in an embodiment of the present application.

[0036] The base 10 may include at least two beams 11 and a plurality of pillars 12 arranged opposite to each other, each beam 11 being used to connect between two adjacent pillars 12. For example, in some embodiments, the base 10 may include two beams 11 and four pillars 12. The two beams 11 are arranged opposite to each other, and the two ends of one beam 11 are respectively connected to two of the pillars 12, and the two ends of another beam 11 are respectively connected to the other two pillars 12. It is understandable that three, four or even more beams 11 may be provided. In addition to some beams 11 arranged opposite to each other and connected to the pillars 12, other beams 11 may also be connected between two opposite beams 11, so that the four pillars 12 are connected as one, so that the four pillars 12 can be mutually restrained, thereby improving the integrity and structural strength of the base 10, and finally improving the stability of the movement of the lifting platform 20. In addition, the pillars 12 may not be limited to four, but may be provided with five, six or even more. The number of pillars 12 and the distribution positions between the plurality of pillars 12 may be designed according to the structure of the lifting platform 20, the weight of the clothing processing device and the load of the clothing processing device.

[0037] In some embodiments, the base 10 may further include a buffer pad 13, which is mounted on the end of the pillar 12 away from the lifting platform 20. Preferably, the buffer pad 13 can be made of rubber or other suitable soft materials. By sleeve-mounting the soft buffer pad 13 on the end of the pillar 12 away from the lifting platform 20, the pillar 12 can be effectively prevented from crushing the supporting surface (such as the ground) under the action of a large axial pressure, and the base 1 can also be prevented from generating harsh noise when moving.

[0038] See also Figure 1 , Figure 3 and Figure 5 , Figure 5The structural diagram of the lifting platform 20 provided in the embodiment of the present application. The lifting platform 20 includes a support plate 21 and a plurality of guide pillars 22, the support plate 21 is connected to one end of the plurality of guide pillars 22, a plurality of pillars 12 of the base 10 are provided with guide channels 121, and the guide pillars 22 can be movably assembled in the guide channels 121, so that the support plate 21 can move up and down relative to the base 10 along the direction of gravity. For example, in some embodiments, the support plate 21 may be a rectangular structural plate, and four guide posts 22 may be provided, and the four guide posts 22 are respectively provided at the four corners of the rectangular support plate 21, and the guide posts 22 have an outer shape that matches the guide channel 121 of the pillar 12, so that each guide post 22 can be slidably assembled in the guide channel 121 of each pillar 12, thereby, when the crank mechanism 30 connected between the lifting platform 20 and the base 10 drives the lifting platform 20 to move, the lifting platform 20 can only move up and down relative to the base 10 along the direction of gravity, and the freedom of the lifting platform 20 relative to the base 10 in other directions is limited, thereby ensuring the stability of the movement of the lifting platform 20. Similarly, the guide posts 22 are not limited to four, and five, six or even more guide posts 22 can be provided, and the number of guide posts 22 and the distribution positions of the plurality of guide posts 22 can be designed according to the structure of the base 10, the weight of the clothing processing device and the load of the clothing processing device.

[0039] In order to limit the relative position of the lifting platform 20 with respect to the base 10, so as to better enable the clothing processing equipment installed on the lifting platform 20 to be maintained at a desired height position, the liftable base 1 can also include a limiter (not shown in the figure). Accordingly, the support column 12 can be provided with a plurality of first limiter holes 122 along the direction of gravity, and the guide column 22 can be provided with a plurality of second limiter holes 221 along the direction of gravity. The limiter can be provided with a first limiter hole 122 and a second limiter hole 221. Exemplarily, the limiting member can be a screw or any other suitable component that can penetrate the first limiting hole 122 and the second limiting hole 221 to perform the limiting function. Each pillar 12 of the base 10 can be provided with a plurality of first limiting holes 122 along the gravity direction, and each guide column 22 of the lifting platform 20 can be provided with at least one second limiting hole 221 along the gravity direction, or, each pillar 12 can be provided with at least one first limiting hole 122, and each guide column 22 can be provided with a plurality of second limiting holes 221, or, each pillar 12 can be provided with a plurality of first limiting holes 122, and each guide column 22 can be provided with a plurality of second limiting holes 221. When any first limiting hole 122 and any second limiting hole 221 are aligned, the limiting member is used to pass through the first limiting hole 122 and the second limiting hole 221 in sequence, so as to avoid the lifting platform 20 from moving downward under the gravity of the clothing processing equipment and its load, thereby maintaining the height position of the lifting platform 20 relative to the base 10.

[0040] See also Figure 1 and Figure 2 In some embodiments, each connecting rod assembly 32 includes a rocker 321 and a connecting rod 322, wherein one end of the rocker 321 is rotatably connected to the lifting platform 20 and the other end is rotatably connected to the connecting rod 322, the connecting rod 322 is slidably connected to the base 10 and the connecting rod 322 is screwed to the rotating connecting shaft 31, when the rotating connecting shaft 31 rotates, the connecting rod 322 can move along the rotating connecting shaft 31, and the connecting rod 322 drives the rocker 321 to swing so that the lifting platform 20 moves up and down. Please refer to Figure 2 and Figure 3 Specifically, the support plate 21 of the lifting platform 20 is connected to one end of the rocker 321 away from the connecting rod 322. In each of the two oppositely arranged beams 11 of the base 10, a slide groove 111 extending along its length direction can be opened on one side of each beam 11 facing the other beam 11, and the two ends of the connecting rod 322 are respectively slidably assembled in a slide groove 111. In other words, both ends of each of the two oppositely arranged cross beams 11 may be provided with a slide groove 111 extending along its length direction, one of the slide grooves 111 of one cross beam 11 is used for sliding connection to one end of the connecting rod 322 of a connecting rod assembly 32, the other slide groove 111 is used for sliding connection to one end of the connecting rod 322 of another connecting rod assembly 32, one of the slide grooves 111 of the other cross beam 11 is used for sliding connection to the other end of the connecting rod 322 of a connecting rod assembly 32, the other slide groove 111 is used for sliding connection to the other end of the connecting rod 322 of another connecting rod assembly 32, the connecting rod 322 is separated from the middle part of the two opposite cross beams 11 and can be screwed to the rotating connecting shaft 31, because the two ends of the connecting rod 322 are slidably assembled in the slide groove 1 11. The middle part is screwed to the rotating connecting shaft 31. When the rotating connecting shaft 31 rotates, the connecting rod 322 in each connecting rod assembly 32 moves axially along the rotating connecting shaft 31 and can drive the rocker 321 to swing relative to the base 10. When the two connecting rod assemblies 32 are close to each other, the swinging motion of the two rockers 321 is converted into an upward motion that drives the lifting platform 20 away from the base 10. When the two connecting rod assemblies 32 are away from each other, the swinging motion of the two rockers 321 is converted into a downward motion that drives the lifting platform 20 to approach the base 10. In order to allow the two relatively arranged connecting rod assemblies 32 to approach or move away from each other when the rotating connecting shaft 31 rotates, the rotation directions of the threads arranged at both ends of the rotating connecting shaft 31 can be opposite.

[0041] See also Figure 1 and Figure 5In order to establish a good connection between the connecting rod assembly 32 and the lifting platform 20, in some embodiments, the lifting platform 20 may also include two frames 23, which are arranged on the side of the support plate 21 facing the base 10, each frame 23 includes a hinged rod 231 and two connecting arms 232, one end of the two connecting arms 232 is respectively connected to the two ends of the hinged rod 231, and the other end of the two connecting arms 232 is separated from the hinged rod 231 and fixed to the support plate 21, and each rocker 321 is rotatably connected to each hinged rod 231 away from the end of the connecting rod 322. Specifically, the two frames 23 can be arranged above the connecting rod 322 and are arranged relatively to each other along the length direction of the connecting rod 322. The rocker 321 of one connecting rod assembly 32 is rotatably connected to the hinge rod 231 of one of the frames 23, and the rocker 321 of the other connecting rod assembly 32 is rotatably connected to the hinge rod 231 of the other frame 23. When the rotating connecting rod rotates, the two connecting rods 322 arranged at both ends of the rotating connecting shaft 31 can approach or move away from each other. In this process, the two ends of each rocker 321 will rotate relative to the connecting rod 322 and the frame 23 respectively, so that the rocker 321 can swing.

[0042] In some embodiments, the rotating connecting shaft 31 can be manually driven to rotate so that the two connecting rod 322 assemblies 32 move closer to or away from each other. In this embodiment, in order to drive the rotating connecting shaft 31 to rotate with less effort, the crank mechanism 30 can also include a toggle handle 33, which is arranged at any end of the rotating connecting shaft 31 away from the connecting rod assembly 32. Specifically, the toggle handle 33 can include a rotating arm 331 and a hand-held portion 332, wherein the rotating arm 331 can be vertically connected to one end of the rotating connecting shaft 31, thereby increasing the force arm and achieving the purpose of labor-saving driving, and the hand-held portion 332 can be arranged at the other end of the rotating arm 331 away from the rotating connecting shaft 31, and the hand-held portion 332 can be perpendicular to the rotating arm 331 and parallel to the rotating connecting shaft 31, so that the user can hold the toggle handle 33. Of course, the liftable base 1 can also include a motor (not shown), which is connected to the rotating connecting shaft 31 to drive the rotating connecting shaft 31 to rotate. When the height position of the clothing processing device needs to be adjusted, it is only necessary to connect the motor to the circuit loop, so that the motor can drive the rotating connecting shaft 31 to rotate, thereby causing the lifting platform 20 to perform a lifting movement to achieve the purpose of adjusting the height position of the clothing processing device. This design saves physical labor and is suitable for users of different ages, especially for young users and elderly users.

[0043] See also Figure 6 , Figure 6The structural diagram of the clothing processing device assembly 100 provided in an embodiment of the present application. The clothing processing device assembly 100 includes a clothing processing device 2 and a liftable base 1, wherein the clothing processing device 2 can be but is not limited to the currently commonly used washing machines, dryers, washing and drying machines, and dehydrators, and the liftable base 1 is the liftable base 1 provided in any embodiment of the present application, and the clothing processing device 2 is mounted on the lift platform 20 of the liftable base 1.

[0044] In order to facilitate a better understanding of the liftable base and clothing processing equipment assembly provided in the embodiment of the present application, the operation steps and implementation principles of the liftable base and clothing processing equipment assembly provided in the embodiment of the present application are further described and introduced below in combination with specific usage scenarios.

[0045] A clothing processing device assembly provided in an embodiment of the present application can, when it is necessary to adjust the height position of the clothing processing device, rotate the toggle handle or turn on the motor power to drive the rotating connecting shaft to rotate around its axis. When it is necessary to adjust the height position of the clothing processing device upward away from the base, rotating the toggle handle in one rotation direction can cause the crank mechanism to drive the lifting platform to move upward. When it is necessary to adjust the height position of the clothing processing device downward toward the base, rotating the toggle handle in the other rotation direction can cause the crank mechanism to drive the lifting platform to move downward.

[0046] Compared with the traditional base and clothing processing equipment assembly, the beneficial effects of the liftable base and clothing processing equipment assembly provided in the embodiment of the present application are: on the one hand, by converting the rotational motion of the rotating connecting shaft into a motion that can drive the lifting platform to move upward or downward relative to the base, the height position of the clothing processing equipment can be easily adjusted to adapt to the use of the clothing processing equipment by different user groups; on the other hand, by using a motor to connect the rotating connecting shaft to drive the rotating connecting shaft to rotate, when the height position of the clothing processing equipment needs to be adjusted, it is only necessary to connect the motor to the circuit loop. This design saves physical operation and is especially friendly to young users and elderly users.
