In some embodiments, the hand-held assembly 1 includes a first housing 13 and a second housing 14, the first housing 13 and the second housing 14 being disposed in opposition, and a mounting cavity being formed between the first housing 13 and the second housing 14.
As shown in fig. 2, the hand-held component 1 is formed by two first shells 13 and second shells 14 which are generally symmetrical in structure and are oppositely arranged, and a mounting cavity is formed between the two shells. The two shells are connected together by bolts. It will be appreciated that in other embodiments, the two housings may be snap-fit connected.
In some embodiments, the positions of the second motor 22 and the third motor 38 are arranged at the front end of the tableware, so that the center of gravity of the whole tableware is arranged in front, the impedance moment in use is increased, before the motors actively eliminate the vibration, the effective passive vibration elimination can be performed preliminarily by utilizing the inertia effect of the tableware, and the load of the tableware is reduced.
In some embodiments, a flexible connector is provided between the clamping assembly 3 and the second housing 24, a first end of the flexible connector being connected to the clamping assembly 3 and a second end of the flexible connector being connected to the second housing 24.
Since the front center of gravity can cause the impedance moment to be increased, and the hands of a patient are easy to fatigue when the patient uses the hand-holding clamp, the connecting part of the clamping assembly 3 and the second shell 24 is designed to be a flexible part so as to buffer the hand strain.
It will be appreciated that in other embodiments, mount 30 may be designed as a flexible member. Preferably, the mounting seat 30 is made of plastic material, such as rubber.
The controller of the anti-shake tableware mainly comprises a circuit control board with a shake elimination algorithm, and is used for controlling the movement of three motors and counteracting the shake of the hands of a patient.
The controller also comprises an angular velocity sensor, an acceleration sensor and the like. The angular velocity sensor and the acceleration sensor are used for detecting the direction and the speed of real-time movement of the tableware and transmitting data to the circuit control board, and the circuit control board controls the two motors to properly rotate and move in the opposite direction through calculation so as to offset the hand shaking of a patient.
It should be noted that the angular velocity sensor and the acceleration sensor must be installed in the grip. The circuit control board can be arranged in the mounting cavity or can be separately integrated outside to form a control box. The power switch may be located at the upper or lower end of the handle portion 11 or at the control box.
Preferably, an angular velocity sensor and an acceleration sensor are integrated in the MPU 6050.
Preferably, the first motor 21 is a dc brushless external rotor motor RMD-S-2408 with built-in encoder and drive.
The controller also has a switch button for controlling the opening and closing of the tableware holding component 3. When the tableware is not used, the two clamping arms are combined together, and when the tableware is used for clamping food, the clamping arms are opened by pressing the switch button; and then the switch button is pressed, and the clamping arms are clamped together to clamp the food.
It should be noted that the positions of the switch buttons are arranged at different positions according to the shape of the handheld component 1. As shown in fig. 3, the switch button is located inside the circular boss on one side of the motor fixing sleeve 15.
It will be appreciated that in other embodiments, such as in a pistol grip, a switch button is mounted in the trigger position.
In other embodiments, the power supply of the anti-shaking tableware can adopt a direct current type or an alternating current to direct current type. The direct current mode is that the controller and the storage battery are integrated in the mounting cavity to provide power for the tableware. The controller is connected with a household 220V power supply in an alternating current mode, and an alternating current-to-direct current component is arranged in the controller.
