Example 1

As shown in fig. 1 to 3, in a first embodiment of the present utility model, an adjustable support assembly 10 is provided, the adjustable support assembly 10 may be disposed at the bottom of a case 110 of a home appliance 100, and an operator may adjust the placement position of the home appliance 100 by adjusting the support height of the adjustable support assembly 10, thereby facilitating the installation and placement of the home appliance 100.

And in case that the placement plane of the home appliance 100 is uneven, an operator can also make the gaps 135 of the home appliance 100 on the left and right sides of the cabinet uniform by adjusting the adjustable support assembly 10 at the bottom of the case 110, so that the appearance of the home appliance 100 after installation is more beautiful.

In this embodiment, the adjustable support assembly 10 includes a mounting base 11, a foot 13 movably connected to the mounting base 11, a pushing structure 15 slidably disposed with respect to the mounting base 11, and a driving member 17 connected to the pushing structure 15. The mounting base 11 may be disposed at the bottom of the case 110, and the mounting base 11 includes a fixing portion 111 connected to the foot 13, a sliding portion 112 matched with the pushing structure 15, and a supporting portion 113 connected to the driving member 17.

In other embodiments, the foot 13 and the pushing structure 15 may also be directly connected to the bottom of the household appliance 100. I.e. the bottom plate of the case 110 is provided with a structure cooperating with the feet 13 and the pushing structure 15 to form the mounting base 11, it is also understood that the mounting base 11 may be provided integrally with the case 110.

The foot 13 has a leg portion 131, and the leg portion 131 has a first position, and a second position away from the fixing portion 111 in a vertical direction with respect to the first position. That is, in the height direction of the home appliance 100, the height of the leg portion 131 in the first position is greater than the height of the leg portion 131 in the second position. The supporting height of the adjustable supporting assembly 10 increases when the leg portion 131 moves from the first position to the second position; the support height of the adjustable support assembly 10 decreases as the leg 131 moves from the second position to the first position.

During use of the adjustable support assembly 10, the driving member 17 may drive the pushing structure 15 to slide relative to the mounting base 11, and the pushing structure 15 pushes the foot 13 to move relative to the mounting base 11, so that the foot 131 moves between the first position and the second position to adjust the supporting height of the adjustable support assembly 10.

In this embodiment, the foot 13 is rotatably connected to the mounting 11. When the pushing member 151 moves in the first direction, the pushing member 151 pushes the foot 13 to rotate relative to the mounting base 11, so that the leg 131 moves from the first position to the second position, so as to increase the supporting height of the adjustable supporting assembly 10. When the pushing member 151 moves in the second direction, the foot 13 rotates relative to the mounting seat 11 under the gravity of the home appliance 100, so that the leg 131 moves from the second position to the first position to reduce the supporting height of the adjustable supporting assembly 10.

The first direction and the second direction are two directions deviating from each other, and are mainly used for describing the movement direction of the pushing member 151 conveniently. Alternatively, the first direction and the second direction may be disposed along the front-rear direction of the apparatus, and the second direction may be disposed forward if the first direction is rearward.

Specifically, the foot 13 is rotatably connected to the fixing portion 111. The fixing portion 111 may be located at a front end of the sliding portion 112. When the supporting height of the adjustable supporting component 10 needs to be increased, the pushing structure 15 can move forward, and the pushing structure 15 pushes the foot 13 to rotate downwards relative to the front end of the fixing portion 111, so that the leg portion 131 moves from the first position to the second position.

When the supporting height of the adjustable supporting assembly 10 needs to be reduced, the driving member 17 drives the pushing member 151 to move backward, and the foot 13 rotates upward relative to the rear end of the fixing portion 111 under the action of gravity of the household appliance 100, so that the leg portion 131 moves from the second position to the first position. In addition, in other embodiments, the fixing portion 111 may be further disposed at a rear end of the sliding portion 112, as in the third embodiment shown in fig. 6 and 7.

In this embodiment, the driving member 17 includes a screw 171 connected to the pushing structure 15. The screw rod 171 may be hinged to the pushing structure 15, and the screw rod 171 is in threaded connection with the supporting portion 113. The screw 171 is rotatable relative to the pushing structure 15 about the axis of the screw 171 and cannot move relative to the pushing structure 15. When the screw rod 171 rotates relative to the support portion 113, the pushing structure 15 and the screw rod 171 move synchronously relative to the mounting seat 11, and the pushing structure 15 pushes the foot 13 to move, so that the foot 131 moves between the first position and the second position.

Alternatively, the outer circumference of the screw rod 171 may be provided with a thread, the supporting portion 113 may be provided with a threaded hole 121 through which the screw rod 171 passes, and the screw rod 171 is movably disposed in the threaded hole 121, so as to implement threaded connection between the screw rod 171 and the supporting portion 113.

In this embodiment, the pushing structure 15 includes a pushing member 151 abutting against the foot 13. The pushing member 151 is slidably disposed with respect to the mounting base 11, the pushing member 151 has an upper surface 1511 abutting against the mounting base 11, and a lower surface 1512 abutting against the foot 13, and a thickness between the upper surface 1511 and the lower surface 1512 varies along a sliding direction thereof.

During the movement of the pushing member 151 relative to the mounting base 11, the thickness variation between the upper surface 1511 and the lower surface 1512 can enable the foot 13 to move in the up-down direction relative to the mounting base 11, so as to change the position of the foot portion 131, so as to adjust the supporting height of the adjustable supporting assembly 10.

Further, the pusher 151 has a front end and a rear end, which may be disposed according to the front-rear direction of the home appliance 100. The thickness between the upper surface 1511 and the lower surface 1512 is set to gradually decrease from the rear end toward the front end. As the pushing member 151 moves forward from the rear, the pushing member 151 pushes the foot 13 against the mount 11 through the lower surface 1512 to move downward, so that the leg portion 131 moves from the first position to the second position, so that the supporting height of the adjustable supporting assembly 10 increases.

Upon forward-rearward movement of the pusher 151, the foot 13 moves upwardly relative to the mount 11 under the interaction between the pusher 151 and the foot 13 and/or the gravitational force of the household appliance 100, such that the leg 131 moves from the second position to the first position, such that the support height of the adjustable support assembly 10 is reduced.

In this embodiment, the pushing structure 15 further includes a transmission member 152 connected to the driving member 17, and a rotating shaft is disposed between the pushing member 151 and the transmission member 152, so that the pushing member 151 can rotate up and down relative to the transmission member 152. In the sliding process of the screw rod 171 driving the pushing member 151, the pushing member 151 may rotate up and down around the transmission member 152, so as to avoid the bending force generated by the inconsistent driving direction of the driving member 17 and the moving direction of the pushing member 151, and influence the transmission of the driving member 17 and the pushing member 151. The push member 151 may be rotated up and down with respect to the transmission member 152, which may be understood as the push member may swing up and down with respect to the transmission member 152 in the up and down direction of the home appliance 100.

Further, the transmission member 152 has a first end 1521 connected to the screw rod 171, and a second end 1522 rotatably connected to the pushing member 151, and the pushing member 151 may swing up and down around the second end 1522, so as to avoid bending force generated when the moving direction of the screw rod 171 is inconsistent with the sliding direction of the pushing member 151, and further ensure transmission efficiency between the transmission member 152 and the pushing member 151.

Still further, the pushing structure 15 further includes a connection shaft 153, and the transmission member 152 and the pushing member 151 are connected by the connection shaft 153. The axis of the connection shaft 153 may be perpendicular to the axis of the screw rod 171, and the connection shaft 153 may be disposed in a horizontal direction, so that the screw rod 171 may drive the pushing member 151 to move through the transmission member 152 and the connection shaft 153.

In this embodiment, the screw 171 and the transmission member 152 may be hinged to each other. When the screw rod 171 rotates relative to the supporting portion 113, the screw rod 171 drives the transmission member 152, the connection shaft 153, and the pushing member 151 to move synchronously, and the pushing member 151 pushes the foot 13 to move relative to the mounting base 11, so that the foot portion 131 moves between the first position and the second position.

Further, the adjustable support assembly 10 further includes an axial limiting structure connecting the transmission member 152 and the screw rod 171, so that the screw rod 171 can rotate relative to the transmission member 152 and cannot move relative to the transmission member 152.

Optionally, the axial limiting structure can be configured as a shaft shoulder, a shaft sleeve, a bearing and the like. The transmission member 152 and the screw rod 171 may be connected by a bearing, so that not only the connection stability between the screw rod 171 and the transmission member 152 can be improved, but also the abrasion between the screw rod 171 and the transmission member 152 can be reduced.

In this embodiment, the foot 13 includes a pair of side plates 133 disposed opposite to each other, a guide wheel 134 disposed between the pair of side plates 133, and a rotating portion 132 disposed on the side plates 133 away from the leg portion 131, and the rotating portion 132 and the leg portion 131 are disposed on both ends of the side plates 133, respectively. The rotating part 132 is rotatably connected to the mounting seat 11.

A gap 135 is formed between the rotating part 132 and the guide wheel 134 for the pushing member 151 to pass through, and the pushing member 151 can move in the gap 135 to adjust the distance between the rotating part 132 and the guide wheel 134 in the up-down direction, thereby adjusting the position of the leg part 131 and adjusting the supporting height of the adjustable supporting assembly 10.

Specifically, the rotating portion 132 and the supporting leg portion 131 are respectively located at two ends of the side plate 133, the rotating portion 132 may be connected to the mounting base 11 through a rotating shaft 1321, the pair of side plates 133 are respectively located at two axial ends of the rotating shaft 1321 and are movably connected to the rotating shaft 1321, the guide wheel 134 is disposed between the rotating portion 132 and the supporting leg portion 131, and the guide wheel 134 may be rotatably connected to the pair of side plates 133 through a central shaft. The guide wheels 134 can reduce friction between the pusher 151 and the foot 13, so that driving force required for the movement of the pusher 151 can be reduced.

The pair of side plates 133, the guide wheel 134, and the rotation shaft 1321 enclose a gap 135 through which the pushing member 151 passes. The upper surface 1511 of the pushing member 151 abuts against the rotating shaft 1321, the lower surface 1512 of the pushing member 151 abuts against the guide wheel 134, and the pair of side plates 133 are respectively located at the left side and the right side of the pushing member 151, so that the sliding direction of the pushing member 151 can be limited, the pushing member 151 is prevented from moving along the axial direction of the rotating portion 132, and structural stability of the adjustable supporting assembly 10 in the lifting process is ensured.

In this embodiment, the adjustable support assembly 10 further includes at least two rotating wheels 115 disposed on the mounting base 11, and the at least two rotating wheels 115 are abutted against the upper surface 1511 of the pushing member 151.
