[0002] With the continuous development and progress of society, intelligent home appliances are becoming more and more popular. In order to make the operation of home appliances or other equipment more humane, the actuator is often required to be able to switch between automatic operation and manual operation. At present, the existing actuators usually use electromagnetic clutches to achieve the switching between automatic operation and manual operation. After the electromagnetic clutch is integrated into the actuator, the actuator is larger in size. In order to ensure a certain clutch force, the electromagnetic clutch used is larger in size, occupies a larger space, and affects the aesthetics. In addition, the electromagnetic clutch has problems such as high cost, low stability, insufficient clutch force, and high power consumption.

[0003] Therefore, the above problems need to be solved urgently. Summary of the invention

[0004] Purpose of the invention: In order to overcome the above shortcomings, the present invention provides an actuator with a mechanical and manual clutch, which has a simple structure and is easy to manufacture. The clutch function is achieved through a flexible connection, which reduces the overall height of the actuator, reduces the space occupied by the actuator, and can manually open or close the door body. It is simple to operate and has high reliability.

[0005] Technical solution: In order to achieve the above-mentioned purpose, the present invention provides an actuator with a mechanical and manual clutch, including a housing, the housing including an upper shell and a lower shell, and the upper shell and the lower shell form a hollow cavity. A motor, a first clutch gear, and a second clutch gear are connected to the bottom of the lower shell. The first clutch gear and the second clutch gear shaft are connected between the upper shell and the lower shell. The motor is driven to connect with the first clutch gear, and the first clutch gear and the second clutch gear are driven to connect. The second clutch gear is driven to connect with the output shaft, and the second clutch gear is slidably arranged along the axis. The second clutch gear is moved to separate the second clutch gear from the output shaft. The first clutch gear includes an outer clutch gear and an inner clutch wheel, and the outer clutch gear and the inner clutch wheel are coaxially flexibly connected. When the door body encounters resistance, the outer clutch gear rotates relative to the inner clutch wheel. The present invention is used for automatic and manual door opening or closing. In the application, the actuator needs to be connected to a box with an opening, and the output shaft provided on the actuator is connected to the door body. The actuator drives the door body to open or close. Specifically, it includes: when the door body needs to be opened automatically, the motor is started, the motor drives the first clutch gear to rotate, the first clutch gear drives the second clutch gear to rotate, and the second clutch gear drives the output shaft to rotate, thereby driving the door body to open or close. When the door body encounters an obstruction, the outer clutch gear rotates relative to the inner clutch wheel to avoid damage to the actuator. When the obstruction of the door body is eliminated, the outer clutch gear and the inner clutch wheel rotate synchronously. When the door body needs to be opened or closed manually, the second clutch gear and the output shaft are separated, and the door body can be opened or closed manually to avoid damage to the actuator. When the door body switch needs to be automatically controlled, the gear coaxially connected to the second clutch gear and the output shaft is meshed to restore the automatic control state. The present invention has a simple structure and is easy to manufacture. The clutch function is realized through a flexible connection, the overall height of the actuator is reduced, and the space occupied by the actuator is reduced. The door body can be opened or closed manually, and the operation is simple and the reliability is high.

[0006] Furthermore, in the above-mentioned actuator with mechanical and manual clutch, a clutch shaft is passed through the axis of the second clutch gear, and a support plate is integrally provided on the clutch shaft, and the support plate supports the second clutch gear. A spring is provided at the end of the second clutch gear away from the support plate, and the spring is sleeved on the outside of the clutch shaft, and one end of the spring abuts against the upper shell, and the end of the spring away from the upper shell abuts against the second clutch gear. The lower end of the clutch shaft is axially connected to the countersunk hole provided in the lower shell, and the upper end of the clutch shaft passes through the upper shell. A handle cap is connected to the upper end of the clutch shaft, and the handle cap is slidably connected to the through groove provided in the upper shell, and the cross-section of the handle cap is set to be square. When the second clutch gear abuts against the support plate, the second clutch gear and the gear coaxially connected to the output shaft are meshed, and the second clutch gear drives the output shaft to rotate. When the second clutch gear and the output shaft need to be separated, the handle cap is grasped and lifted to drive the second clutch gear and the output shaft to separate. At this time, the handle cap leaves the through slot provided on the upper shell, the handle cap is rotated to a certain angle, the handle cap is released, the lower end of the handle cap is abutted against the top surface of the upper shell, and the handle cap is prevented from falling into the through slot provided on the upper shell. The second clutch gear compresses the spring, and the second clutch gear and the output shaft remain separated. When the second clutch gear and the output shaft need to be driven and connected, the handle cap is grasped and rotated to a certain angle so that the handle cap is directly opposite to the through slot provided on the upper shell, the handle cap is released, the spring presses the second clutch gear downward, the handle cap slides into the through slot provided on the upper shell, the gear coaxially connected with the second clutch gear and the output shaft is meshed, and the second clutch gear can drive the output shaft to rotate. When the second clutch gear needs to be clutched for manual operation, only the handle cap needs to be moved, which is simple to operate, easy to learn, and meets the needs of different groups of people.

[0007] Furthermore, in the above-mentioned actuator with mechanical and manual clutch, the outer clutch gear is annular, the outer wall of the outer clutch gear is provided with outer teeth, the inner wall of the outer clutch gear is wavy, the inner clutch wheel is disc-shaped, and the outer wall of the inner clutch wheel is set to a wavy shape corresponding to the inner wall of the outer clutch gear. The outer clutch gear and the inner clutch wheel are both set to be wavy, and the outer clutch gear and the inner clutch wheel are respectively set to have a certain elastic plastic. When the door body is blocked, the inner clutch wheel is stuck, the outer clutch gear squeezes the inner clutch wheel, the contact part of the two is elastically deformed, and the outer clutch gear and the inner clutch wheel slip, avoiding damage to the inside of the actuator. When the obstruction to the door body is eliminated, the elastic deformation of the contact part of the outer clutch gear and the inner clutch wheel is restored, the outer clutch gear and the inner clutch wheel are pressed together, and the outer clutch gear drives the inner clutch wheel to rotate, thereby driving the door body to open or close. Through the wave-shaped structure setting, automatic clutch is realized, which can prevent the actuator from being damaged due to overload, extend the service life of the actuator, prevent people from being pinched, improve the safety of the equipment, and the actuator can automatically resume normal operation, improving the automation and self-adaptation capabilities of the actuator.

[0008] Furthermore, in the above-mentioned actuator with mechanical and manual clutch, the outer clutch gear and the inner clutch wheel are frictionally connected, and the outer clutch gear drives the inner clutch wheel to rotate. The outer clutch gear and the inner clutch wheel are frictionally connected to form a friction clutch, which can reduce the impact on the internal gears of the actuator during the startup process, improve the stability of power transmission, and when the door body is blocked, the outer clutch gear and the inner clutch wheel can slip due to insufficient friction, avoiding damage to the actuator due to excessive torque. When the load is less than the friction, the transmission effect can be quickly restored.

[0009] Furthermore, in the above-mentioned actuator with mechanical and manual clutch, the outer clutch gear and the inner clutch wheel are magnetically connected, and the outer clutch gear drives the inner clutch wheel to rotate. The magnetic connection between the outer clutch gear and the inner clutch wheel can ensure that when the door body is blocked, the outer clutch gear and the inner clutch wheel slip due to insufficient magnetic force, and can also quickly restore transmission when the obstruction is eliminated. There is no direct mechanical contact, deformation and friction in the magnetic transmission, which can increase the service life of the actuator, reduce the maintenance frequency, and reduce the cost of use.

[0010] Furthermore, in the above-mentioned actuator with mechanical and manual clutch, the motor shaft of the motor is connected with a worm, and the first clutch gear is set as a worm corresponding to the worm. The transmission mode of the worm wheel and the worm can set a larger transmission ratio to improve the output torque of the motor, and the self-locking characteristics of the worm wheel and the worm can lock the door body at a certain angle to prevent the door body from closing due to its own weight when it is open.

[0011] Furthermore, in the above-mentioned actuator with mechanical and manual clutch, a gear set is provided between the upper shell and the lower shell, the gear set is respectively meshed with the first clutch gear and the second clutch gear, and the first clutch gear drives the second clutch gear to rotate through the gear set. The first clutch gear and the second clutch gear are connected by the gear set, and the gear ratio of the gear set can be adjusted, thereby adjusting the output torque and output speed, thereby improving the adaptability and flexibility of the actuator.

[0012] Furthermore, in the above-mentioned actuator with mechanical and manual clutch, the gear set includes a transmission gear, the transmission gear and the first clutch gear are coaxially and synchronously connected, the transmission gear is drivingly connected to the first double gear, the first double gear is drivingly connected to the second double gear, and the second double gear is drivingly connected to the second clutch gear. Designing multiple double gears in the gear set makes the actuator design more compact and improves the space utilization of the actuator. The two gears of the double gear are arranged on the same shaft, which can reduce torque loss and improve transmission efficiency. Multiple double gears facilitate the realization of multiple transmission ratios to meet different power transmission and numerical control requirements.

[0013] Furthermore, in the above-mentioned actuator with mechanical and manual clutch, the first double gear includes a first toothed disc and a first toothed column, the first toothed disc and the first toothed column are coaxially connected as a whole, the first toothed disc is arranged on the upper side of the first toothed column, and the first toothed disc is meshed with the transmission gear. The second double gear includes a second toothed disc and a second gear, the second toothed disc and the second gear are coaxially synchronously connected, the second toothed disc is arranged on the lower side of the second gear, the second toothed disc is meshed with the first toothed column, and the second gear is meshed with the second clutch gear. The staggered design of the first double gear and the second double gear makes full use of the internal space of the actuator, improves space utilization, and makes the actuator more compact.

[0014] Furthermore, in the above-mentioned actuator with mechanical and manual clutch, the upper shell shaft is connected to an angle gear, and the angle gear is meshed with the second clutch gear. The upper shell is connected to a square plate, the square plate is connected to an angle sensor, the angle gear shaft is connected to the angle sensor, and a notch is provided on the connecting shaft connecting the angle gear and the angle sensor. The angle sensor detects the notch provided on the connecting shaft between the angle gear and the angle sensor, and then monitors the rotation angle of the angle gear, identifies the opening angle of the door body, and realizes automatic control of the door body by combining the start and stop control of the motor.

[0015] It can be seen from the above technical scheme that the present invention has the following beneficial effects: simple structure, easy to manufacture, clutch function achieved through flexible connection, reduced overall height of the actuator, reduced space occupied by the actuator, and the door body can be opened or closed manually, simple to operate, and highly reliable. When the second clutch gear needs to be engaged for manual operation, only the handle cap needs to be moved, which is simple to operate, has low learning difficulty, and can meet the needs of different groups of people.
