Description

Technical Field

[0001] The utility model relates to the technical field of control, in particular to a door opening and closing control device. Background Art

[0002] In order to make full use of the space, some cabinets have storage spaces arranged front and back. Shelves for collecting items are arranged inside the cabinets, and the front and back of the shelves are carrying spaces. The shelves are rotatably arranged inside the cabinets. By rotating the shelves, the carrying space is moved to the front of the cabinet, and items can be taken from the carrying space or placed in the carrying space. The existing technology is to manually rotate the shelves, which is troublesome to use and difficult to rotate into place at one time. Summary of the invention

[0003] The purpose of the invention of the utility model is to provide a storage rack rotation control device which can overcome one or more of the above-mentioned shortcomings, rotate smoothly, prevent fingers from being pinched, has a rich cabinet door travel, and can meet various usage requirements.

[0004] The utility model storage rack rotation control device is implemented as follows, including a cabinet, a rack driven to rotate by a motor power mechanism, and a control device for controlling the operation of the motor power mechanism, the rack is divided into more than two parts along the circumference, the two adjacent parts are separated by a vertical partition, and each part is divided into more than two loading grids from bottom to top, and the special feature of the utility model is that the control device includes a sensor for sensing human body, an MCU control circuit, a sensing controller, and a reset sensor arranged on the inner side of the cabinet frame of the cabinet, the MCU control circuit is an MCU control circuit that controls the motor power mechanism to run at a set speed and a set time through a program to drive the rack to rotate a set distance, the sensor for sensing human body includes a touch sensing component arranged on the side of the cabinet frame, and a sensing circuit connected to the touch sensing component and capable of sensing capacitance changes, and the signal output end of the sensing controller, the signal output end of the reset sensor, and the electrical signal output end of the sensing circuit are connected to the matching electrical signal input end of the MCU control circuit.

[0005] During operation, when a part of the shelf needs to be turned to the front of the cabinet, the induction controller is touched (such as touching the touch button on the cabinet door by hand, or shaking the hand in front of the touch switch of the cabinet door, or through voice control). After the MCU control circuit receives the signal from the induction controller, it controls the motor power mechanism to work at a set speed for a set time according to a preset control program until the required part is turned to the front of the cabinet, and the items on the loading grid on the part are presented in front of the user on the front of the cabinet, so that the user can easily extract the required items. Since there is no need to touch the mechanical switch for stroke control, there will be no touch switch sound, and since there is no need to manually turn the shelf, it is easy to use;

[0006] Since the MCU control circuit controls the motor power mechanism to work at a set speed and for a set time according to a preset control program, multiple running strokes can be set so that the shelf can match each part and move in sections to achieve full presentation of each part. Such control only requires setting multiple control modes (such as multiple gestures or multiple languages). The cabinet door has a rich stroke range to meet a variety of usage requirements.

[0007] When the vertical partition of the shelf passes through the reset sensor, the reset sensor is triggered. After the MCU control circuit receives the control signal of the reset sensor, it controls the starting position of the motor power mechanism to return to zero, so as to prevent the cumulative error caused by multiple rotations of the shelf, resulting in the wrong rotation position of the shelf.

[0008] When the shelf is rotating, a person's hand reaches into the shelf, causing the vertical partition to contact the person's hand, and the touch sensing component on the side of the cabinet frame to contact the person's hand, causing the circuit characteristics of the sensor that senses the human body to change, and then causing the nature of the output electrical signal to change (for example, under normal circumstances, the capacitance of the sensor that senses the human body is C1, and the output electrical signal is I1. The contact between the touch sensing component and the person's hand causes the capacitance to change to C2, and the corresponding electrical signal changes to I2). After the MCU control circuit senses the change in the electrical signal, it determines that the person's hand is within the range of closing the arc-shaped cabinet door, and controls the motor power mechanism to stop working until the person's hand leaves the touch sensing component on the side of the cabinet frame and the output electrical signal returns to the original signal characteristics. Only then does the MCU control circuit sense the change in the electrical signal and control the motor power mechanism to continue working.

[0009] Compared with the prior art, the utility model has the advantages of no touch switch sound, smooth rotation, prevention of finger pinching, rich cabinet door travel, and ability to meet various usage requirements. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The storage rack rotation control device of the utility model is now described in further detail in conjunction with the accompanying drawings and embodiments:

[0015] As shown in the figure, the storage rack rotation control device of the utility model is implemented as follows, including a cabinet 1 with a cabinet door 101, a shelf 3 driven to rotate by a motor power mechanism 2, and a control device 4 for controlling the operation of the motor power mechanism 2. The shelf 3 is divided into more than two parts 301 along the circumference, and the two adjacent parts 301 are separated by a vertical partition 302. Each part 301 is divided into more than two loading grids 303 from bottom to top. The special feature of the control device 4 is that it includes a sensor 401 for sensing the human body, an MCU control circuit 402, a sensing controller 403, and a reset sensor arranged on the inner side of the cabinet frame of the cabinet 1. The MCU control circuit 402 is an MCU control circuit that controls the motor power mechanism 2 to run at a set speed and a set time through a program to drive the shelf 3 to rotate a set distance. The sensor 401 for sensing the human body includes a touch sensing component 4011 arranged on the side of the cabinet frame of the cabinet 1, and a sensing circuit 4012 that can sense capacitance changes and is connected to the touch sensing component 4011. The signal output end of the sensing controller 403, the signal output end of the reset sensor 404, and the electrical signal output end of the sensing circuit 4012 are connected to the matching electrical signal input end of the MCU control circuit 402.

[0016] Preferably, a switch structure 4013 is provided between the touch sensing member 4011 and the side of the cabinet frame of the cabinet 1 (for example, a conductive strip is provided on the side of the cabinet frame of the cabinet 1, and the touch sensing member 4011 is a metal conductive strip, and an insulating elastic space is provided between the conductive strip and the touch sensing member 4011. When the human body is touched, the conductive strip and the touch sensing member 4011 touch each other, thereby forming a loop through the human body grounding, thereby outputting a signal to the MCU control circuit 402 through the sensing circuit 4012, and controlling the shelf 3 to stop rotating, thereby achieving the effect of preventing finger pinching). With the switch structure 4013, even if a conductive foreign object (such as water droplets) contaminates the touch sensing member 4011, since the switch structure 4013 is in an off state, the sensing circuit 4012 will not be triggered to send a control signal to the MCU control circuit 402.

[0017] During operation, when a part of the shelf 3 needs to be turned to the front of the cabinet 1, the sensing controller 403 is touched (for example, by touching the touch button on the cabinet door with the hand, or by shaking the hand in front of the touch switch of the cabinet door, or by voice control). After the MCU control circuit 402 receives the signal from the sensing controller 403, it controls the motor power mechanism 2 to work at a set speed for a set time according to a preset control program until the required part is turned to the front of the cabinet 1, and the items on the loading grid 303 on the part 301 are presented in front of the user on the front of the cabinet 1, so that the user can easily extract the required items. Since there is no need to touch the mechanical switch for stroke control, there will be no sound of touching the switch. Since there is no need to manually turn the shelf 3, it is easy to use.

[0018] When the vertical partition 302 of the shelf 3 passes through the reset sensor 404, the reset sensor 404 is triggered, and after the MCU control circuit 402 receives the control signal of the reset sensor 404, it controls the starting position of the motor power mechanism 2 to return to zero, so as to prevent the cumulative error caused by rotating the shelf 3 multiple times and the wrong rotation position of the shelf 3;

[0019] When the shelf is rotating, a person's hand reaches into the shelf, causing the vertical partition to contact the person's hand, and the touch sensing component on the side of the cabinet frame to contact the person's hand, causing the circuit characteristics of the sensor that senses the human body to change, and then causing the nature of the output electrical signal to change (for example, under normal circumstances, the capacitance of the sensor that senses the human body is C1, and the output electrical signal is I1. The contact between the touch sensing component and the person's hand causes the capacitance to change to C2, and the corresponding electrical signal changes to I2). After the MCU control circuit senses the change in the electrical signal, it determines that the person's hand is within the range of closing the arc-shaped cabinet door, and controls the motor power mechanism to stop working until the person's hand leaves the touch sensing component on the side of the cabinet frame and the output electrical signal returns to the original signal characteristics. Only then does the MCU control circuit sense the change in the electrical signal and control the motor power mechanism to continue working.
