DETAILED DESCRIPTION

[0020] The following is a detailed description of the embodiments of the technical solution of the present invention in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of this patent.

[0021] like Figure 1-Figure 3 As shown, an embodiment of the present invention provides an intelligent dining assistant, including an arm assist mechanism 1 and a tray mechanism 2 for placing dining plates, wherein the arm assist mechanism 1 and the tray mechanism 2 are fixed side by side on a table top.

[0022] Reference Figure 1 and Figure 2 The arm assist mechanism 1 includes a first fixed seat 11, a first mechanical arm 12 installed on the first fixed seat 11, a pressure-sensing hand rest 13 installed on the upper end of the first mechanical arm 12, and a first controller for controlling the movement of the first mechanical arm. The upper part of the pressure-sensing hand rest 13 is provided with an arc-shaped bracket that fits the patient's arm. The pressure-sensing hand rest 13 senses the pressure applied by the patient's arm thereto, and transmits the sensed current pressure to the first controller. The first controller receives the current pressure and compares and analyzes the current pressure with the preset pressure to calculate the movement trend of the patient's arm, and then controls the movement of the first mechanical arm 12 to assist the patient's arm to move in the direction of the movement trend.

[0023] When eating, the patient places his arm in the arc-shaped bracket of the pressure-sensing hand rest 13. The arc-shaped bracket has the function of fixing the patient's arm to prevent the patient's arm from shaking, thereby maintaining the stability of the patient's arm when eating. At the same time, the pressure-sensing hand rest 13 can sense the pressure of various positions of the patient's arm in contact with it. The first controller determines the movement trend of the patient's arm through the pressure signal fed back by the pressure-sensing hand rest 13, and then controls the movement of the first mechanical arm 12 to assist the patient's arm to move in the direction of the movement trend, making it easier for the patient to move his arm when eating. Assisting the patient in eating through the arm assisting mechanism 1 not only solves the patient's dining problem and reduces the burden on nursing staff, but also can provide rehabilitation training for the patient, enhance the patient's confidence, and is conducive to the rehabilitation of the patient's hand disease, killing two birds with one stone.

By swinging the fourth swing arm 126 left and right, the axial inclination of the pressure-sensing hand rest 13 can be controlled so that the patient's arm is always in contact with the arc-shaped bracket of the pressure-sensing hand rest 13 during the movement. In this way, the mechanical arm can flexibly assist the patient's arm to complete actions such as movement, bending and tilting, thereby assisting the patient's arm to eat independently. It should be noted that the swinging of the first swing arm 122, the second swing arm 123, the third swing arm 124 and the fourth swing arm 126 and the rotation of the first rotating arm 121 and the second rotating arm 125 are all driven by corresponding stepping motors.

It should be noted that the swinging of the fifth swing arm 222, the sixth swing arm 223, the seventh swing arm 224 and the rotation of the third rotating arm 221 and the fourth rotating arm 225 are all driven by corresponding stepper motors, and their structure is very common and can be easily implemented by technicians in this field. It is not within the scope of protection of the present application and will not be elaborated on.

[0028] Similarly, the second fixing seat 21 includes a second upper clamping plate 211, a second lower clamping plate 212, a second side plate 213 and a second fixing bolt 214. The second side plate 213 is connected between the second upper clamping plate 211 and the second lower clamping plate 212.

The tray mechanism 2 can be detachably fixed to the desktop panel through the second fixing seat 21. During installation, the second fixing seat 21 is clamped on the desktop panel and the second fixing bolt 214 is tightened. The installation and disassembly are very convenient. In addition, a second fixing rubber pad 215 is provided at the upper end of the second fixing bolt 214, which can not only increase the friction between the desktop and the second fixing bolt 214, making the second fixing seat 21 and the desktop more firmly fixed, but also protect the desktop.

[0029] When a patient is having a meal, his hands may shake, so a tableware holder 24 for fixing the meal plate is provided on the tray 23. The meal plate is fixed by the tableware holder 24 to prevent the meal plate from being knocked over. The dinner plate holder of this embodiment is provided with two structures, wherein one structure of the tableware holder 24 comprises two first fixing rings 241 arranged opposite to each other, one end of the two first fixing rings 241 is rotatably connected to the shaft seat 242 fixed on the tray 23, so that the relative distance between the two first fixing rings 241 can be adjusted by rotating the two first fixing rings 241 around the shaft seat 242, so that the tableware is fixed between the two first fixing rings 241, and the relative distance between the two first fixing rings 241 can be adjusted by rotating the first fixing rings 241, so as to adapt to the fixing of tableware of different sizes, with strong adaptability and convenient use; the other structure of the tableware holder 24 comprises two second fixing rings 243 arranged opposite to each other, and the tray 23 is provided with a first slide seat 244 and a second slide seat 245 which can slide relatively, wherein one end of one second fixing ring 243 is fixed on the first slide seat 244, and the other second fixing ring 243 is fixed on the second slide seat 245, so that the relative distance between the two second fixing rings 243 can be adjusted by the relative sliding of the first slide seat 244 and the second slide seat 245.
