DETAILED DESCRIPTION

[0016] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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.

[0017] In the present invention, it needs to be explained that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0018] A cabinet lifting mechanism comprises a lifting base 1, the back of the lifting base 1 is fixedly mounted on the cabinet by screws, a guide fixing base 2 and a motor 3 are respectively installed in the lifting base by screws, and a cloth belt 4 is driven by the motor to move. The guide fixing base is provided with a through hole, and a longitudinal connecting rod 5 is inserted into the through hole, and the longitudinal connecting rod 5 performs lifting and lowering movement in the through hole of the guide fixing base. After the upper end of the longitudinal connecting rod extends longitudinally from the top of the lifting base, an upper transverse connecting rod 6 is fixedly mounted by screws. A hook fixing plate 7 for fixing and mounting a storage basket is fixedly mounted on the upper transverse connecting rod by screws, and the hook fixing plate 7 is fixed to the storage basket by screws. After the lower end of the longitudinal connecting rod extends longitudinally from the bottom of the lifting base, a lower transverse connecting rod 8 is fixedly mounted by screws, and a rotating wheel 9 driven by a cloth belt to lift the longitudinal connecting rod is fixedly mounted on the lower transverse connecting rod by screws, and a varistor sensor 10 is installed in the lifting base by studs or double-sided adhesive to sense that an obstacle is clamped between the storage basket and the cabinet when the longitudinal connecting rod is lifted and lowered, and to control the motor to reverse and stop the movement.

[0019] like Figure 1 - Figure 2 As shown, at this time, the longitudinal connecting rod 5 in the cabinet lifting mechanism is in a state of rising to the top, and the cabinet lifting mechanism rises to the top in the cabinet as shown in FIG. Figure 5As shown. Guide fixing seats are installed on both sides of the lifting base, and longitudinal connecting rods are installed on the guide fixing seats on each side. One end of the upper transverse connecting rod is connected to the longitudinal connecting rod on one side, and the other end is connected to the longitudinal connecting rod on the other side. One end of the lower transverse connecting rod is connected to the longitudinal connecting rod on one side, and the other end is connected to the longitudinal connecting rod on the other side. Guide fixing seats are installed on both sides of the cabinet lifting mechanism, and a longitudinal connecting rod is installed on the guide fixing seats on each side. The upper end of each longitudinal connecting rod is fixed to the two ends of the upper transverse connecting rod by screws, and the lower end is fixed to the two ends of the lower transverse connecting rod by screws, so that the storage basket is more stable when it rises and falls under the drive of the cabinet lifting mechanism.

[0020] Two guide fixing seats are longitudinally installed in the lifting base on each side, and each longitudinal connecting rod is guided by the two guide fixing seats, so that the longitudinal connecting rod is more stable during the rising and falling process.

[0021] The hook fixing piece can be an L-shaped hook fixing piece, one end of which is fixedly mounted on the upper horizontal connecting rod by screws, and the other end is extended forward and fixed to the storage basket by screws. The extended section allows a gap to be reserved between the storage basket and the lifting base, so that the storage basket is prevented from interfering with the lifting base during the lifting process. The hook fixing piece is provided with two pieces, so that the upper horizontal connecting rod and the storage basket can be better fixed. Figure 6 Schematic diagram showing the fixing of the upper transverse connecting rod and the storage basket, Figure 7 This is a schematic diagram of the back assembly of the cabinet lifting mechanism storage basket.

[0022] A circuit board can be installed in the lifting base. The circuit board is electrically connected to the varistor sensor and the motor. The circuit board is provided with an H-bridge circuit and a single-chip microcomputer. The storage basket is lifted and lowered under the drive of the longitudinal connecting rod. The varistor sensor detects that there is an obstacle blocking the lifting movement. The sensing signal is transmitted back to the single-chip microcomputer on the circuit board. The single-chip microcomputer controls the H-bridge circuit to make the motor reverse a short distance and then stop, thereby preventing the obstacle from being clamped. The obstacle is a human hand or other object. The circuit board can also be built into the varistor sensor. The circuit board can be sealed on the end of the varistor sensor with silicone. The circuit board can also be built into the motor. The circuit board can be installed on the circuit at one end of the motor cover.

[0023] One end of the cloth belt can be wound around the motor shaft, and the other end is fixed on the rotating wheel. The cloth belt can be retracted and released on the motor shaft by rotating the motor shaft, thereby driving the rotating wheel. Since the rotating wheel is fixed to the lower transverse connecting rod by screws, the lower transverse connecting rod pushes the longitudinal connecting rod, and the longitudinal connecting rod pushes the upper transverse connecting rod, so that the storage basket is lifted and lowered under the drive of the longitudinal connecting rod. A turbine can also be installed on the guide fixing seat through a rotating shaft, a worm is installed on the motor shaft matched with the turbine, and a cloth belt wheel is installed on the rotating shaft coaxial with the turbine. One end of the cloth belt is wound around the cloth belt wheel, and the other end is fixed on the rotating wheel. The worm is rotated by the motor shaft, thereby driving the vortex and then driving the cloth belt wheel, so that the cloth belt can be retracted and released on the cloth belt wheel, thereby driving the rotating wheel, so that the storage basket is lifted and lowered under the drive of the longitudinal connecting rod.

[0024] A cabinet, such as Figure 3 - Figure 5 As shown, it includes a cabinet body 11 for fixing to the back of the cabinet lifting mechanism, a storage basket 12 installed in front of the cabinet lifting mechanism, an openable cabinet door 13 installed in front of the storage basket, a transverse rod 14 installed on the cabinet body at the bottom of the cabinet door, the transverse rod is located in front of the storage basket, and a gap is reserved between the storage basket and the cabinet door and the transverse rod. The storage basket is raised and lowered under the drive of the cabinet lifting mechanism, and the varistor sensor detects that an obstacle is clamped on the cabinet door or the transverse rod and controls the motor to reverse and stop moving, thereby preventing the obstacle from being clamped, so as to facilitate the storage and retrieval of items.

[0025] The above embodiments are only used to illustrate the detailed scheme of the present invention, and the present invention is not limited to the above detailed scheme, that is, it does not mean that the present invention must rely on the above detailed scheme to be implemented. Those skilled in the art should understand that any improvement of the present invention, equivalent replacement of various raw materials of the product of the present invention, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of the present invention.
