[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0023] In the present application, it needs to be explained that if the directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of the present application, the directional indication is only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indication also changes accordingly.

[0024] A cabinet lifting mechanism, comprising a lifting base 1, the back of the lifting base 1 is fixedly installed on the cabinet through a screw, a guide fixed seat 2 and a motor 3 are respectively installed in the lifting base through a screw, and a cloth belt 4 is driven to move by the motor. The guide fixed seat is provided with a through hole, the longitudinal connecting rod 5 is sleeved in the through hole, and the longitudinal connecting rod 5 moves up and down in the through hole of the guide fixed seat. 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 installed through a screw. The upper transverse connecting rod is provided with a hanging buckle fixing plate 7 for fixedly installing a storage basket, and the hanging buckle fixing plate 7 is fixed with the storage basket through a screw. 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 installed through a screw, and a rotating wheel 9 driven by the cloth belt to make the longitudinal connecting rod move up and down is fixedly installed on the lower transverse connecting rod through a screw. A pressure-sensitive resistance sensor 10 for stopping the movement of the motor after the motor is controlled to reverse when an obstacle is clamped between the storage basket and the cabinet during the lifting of the longitudinal connecting rod is installed in the lifting base through a stud or double-sided adhesive.

[0025] As shown in Figure 1 - Figure 2 At this time, the longitudinal connecting rod 5 in the cabinet lifting mechanism is in a state of rising to the top, and the state of the cabinet lifting mechanism rising to the top in the cabinet is as shown in Figure 5The two sides of the lifting base are provided with guiding fixing bases, and each of the guiding fixing bases is provided with a longitudinal connecting rod. One end of the upper transverse connecting rod is connected with one longitudinal connecting rod, and the other end is connected with the other longitudinal connecting rod. One end of the lower transverse connecting rod is connected with one longitudinal connecting rod, and the other end is connected with the other longitudinal connecting rod. The guiding fixing bases are arranged on the two sides of the cabinet lifting mechanism, and each of the guiding fixing bases is provided with a longitudinal connecting rod. The upper ends of the longitudinal connecting rods are fixed with the two ends of the upper transverse connecting rod by screws, and the lower ends of the longitudinal connecting rods are fixed with the two ends of the lower transverse connecting rod by screws, so that the storage basket is more stable when being lifted up and down by the cabinet lifting mechanism.

[0026] Two guiding fixing bases are longitudinally arranged in each of the lifting bases, and each of the longitudinal connecting rods is guided by the two guiding fixing bases, so that the longitudinal connecting rods are more stable when being lifted up and down.

[0027] The hanging buckle fixing piece can be an L-shaped hanging buckle fixing piece. One end of the hanging buckle fixing piece is fixed on the upper transverse connecting rod by a screw, and the other end of the hanging buckle fixing piece is extended forward and fixed with the storage basket by a screw. The extended section leaves a gap between the storage basket and the lifting base, so that the storage basket does not interfere with the lifting base during lifting. The hanging buckle fixing piece has two pieces, so that the upper transverse connecting rod and the storage basket can be better fixed. Figure 6 A schematic view of the fixing of the upper transverse connecting rod and the storage basket is shown, Figure 7 A schematic view of the assembly of the back of the cabinet lifting mechanism storage basket is shown.

[0028] A circuit board can be arranged in the lifting base. The circuit board is electrically connected with the pressure-sensitive resistance sensor and the motor. The circuit board is provided with an H-bridge circuit and a single-chip microcomputer. The storage basket is lifted up and down by the longitudinal connecting rod. When the pressure-sensitive resistance sensor detects an obstacle blocking the lifting movement, an induction 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 for a short distance and then stop, so as to prevent the obstacle from being clamped. The obstacle can be a hand or other object. The circuit board can be built in the pressure-sensitive resistance sensor. The circuit board can be sealed on the end of the pressure-sensitive resistance sensor by silica gel. The circuit board can be built in the motor. The circuit board can be arranged on the circuit at one end of the motor cover.

[0029] One end of the fabric belt can be wound around the motor shaft, and the other end is fixed to the rotating wheel. Rotation of the motor shaft causes the fabric belt to unwind and rewind, thus 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, which in turn pushes the upper transverse connecting rod, causing the storage basket to rise and fall under the action of the longitudinal connecting rod. Alternatively, a worm gear can be installed on the guide fixing seat via a rotating shaft. A worm gear is mounted on the motor shaft that cooperates with the worm gear, and a fabric belt pulley is mounted on the rotating shaft coaxial with the worm gear. One end of the fabric belt is wound around the pulley, and the other end is fixed to the rotating wheel. Rotation of the worm gear by the motor shaft drives the worm, which in turn drives the fabric belt pulley, causing the fabric belt to unwind and rewind, thus driving the rotating wheel and causing the storage basket to rise and fall under the action of the longitudinal connecting rod.

[0030] A type of cabinet, such as Figure 3 - Figure 5 As shown, the system includes a cabinet body 11 for fixing to the back of the cabinet lifting mechanism, and a storage basket 12 installed in front of the cabinet lifting mechanism. An openable cabinet door 13 is installed in front of the storage basket. A horizontal bar 14 is installed on the cabinet body at the bottom of the door, located in front of the storage basket. Gaps are provided between the storage basket and the cabinet door and the horizontal bar. The storage basket is raised and lowered by the cabinet lifting mechanism. When a pressure-sensitive resistor detects an obstacle being clamped on the cabinet door or the horizontal bar, it controls the motor to reverse and stop moving, thus preventing the obstacle from being clamped and facilitating the storage and retrieval of items.

[0031] The above embodiments are only used to illustrate the detailed solution of this utility model. This utility model is not limited to the above detailed solution, that is, it does not mean that this utility model must rely on the above detailed solution to be implemented. Those skilled in the art should understand that any improvement to this utility model, equivalent substitution of the raw materials of this utility model product, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of this utility model.
