Description

Technical Field

[0001] This utility model belongs to the technical field of home appliance accessories, and specifically relates to a rotary actuator with an energy storage device. Background Technology

[0002] In the home appliance industry, rotary actuators are key components for achieving automation and intelligence. They convert electrical energy or other forms of energy into rotational motion to drive the moving parts within the appliance. Rotary actuators are one of the most widely used types of rotary actuators in home appliances, offering advantages such as high control precision and ease of automation integration. For example, in a smart curtain system, an electric rotary actuator can precisely control the opening and closing angle of the curtains based on a predetermined time or ambient light conditions. In smart refrigerators, they can be used to drive the automatic opening and closing of the refrigerator door.

[0003] For applications involving sudden load changes—short-term heavy loads and otherwise light loads—existing solutions use a combination of push rod and rotary actuators to overcome the heavy load range. However, this structure requires both push rod and rotary actuators, resulting in higher costs and limited installation space. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides a rotary actuator with an energy storage device. It is reasonably designed and has a simple structure. It can store energy through an energy storage slider and release the energy storage slider to help break through the heavy load area under heavy load.

[0005] Technical solution: In order to achieve the above objectives, this utility model provides a rotary actuator with an energy storage device, including a drive worm, an actuator wheel assembly, an energy storage wheel assembly, and an energy storage device; The drive worm gear is poweredly connected to the actuation wheel assembly and the energy storage wheel assembly. The energy storage device includes an energy storage slider, a spring connected to the energy storage slider, and an electromagnet that can be attracted to the energy storage slider. The actuator wheel assembly is equipped with an electromagnetic clutch, which can disconnect the actuator wheel assembly from the drive worm gear. The actuator wheel assembly is also equipped with an extension arm, and the energy storage slider can strike the extension arm to drive the actuator wheel assembly. The energy storage wheel assembly is equipped with a disc, and the disc is equipped with a pawl. When it rotates, the pawl on the upper part can move the energy storage slider.

[0006] Furthermore, the device also includes a housing with a groove on it. The energy storage slider is slidably disposed in the groove, and the spring is disposed in the groove. The electromagnet is disposed on the housing and located at the compressed end of the spring. As the energy storage slider slides in the groove, when the sliding slider compresses the spring, the energy storage slider is attracted by the electromagnet to complete energy storage.

[0007] Furthermore, the actuating wheel assembly and the energy storage wheel assembly are rotatably mounted on the housing, and the electromagnetic clutch is mounted on the housing.

[0008] Furthermore, the actuating gear set includes a first driving helical gear, a first transmission gear poweredly connected to the first driving helical gear, and an actuating gear poweredly connected to the first transmission gear.

[0009] Furthermore, the extendable arm is located at the bottom of the actuating gear, and the first driving helical gear is poweredly connected to the driving worm gear. After the energy storage slider is released, it impacts the extendable arm through the elastic force of the spring, and the extendable arm applies this torque to the actuating gear.

[0010] Furthermore, the energy storage wheel assembly includes a second driving helical gear, a second transmission gear poweredly connected to the second driving helical gear, and an energy storage gear poweredly connected to the second transmission gear.

[0011] Furthermore, the second driving helical gear is poweredly connected to the driving worm gear, and the disk is coaxially positioned below the energy storage gear. When the driving worm gear drives the energy storage wheel assembly, the energy storage gear drives the disk to rotate, and the pawl on the disk moves the energy storage slider to compress its spring.

[0012] Furthermore, the energy storage slider is provided with a protrusion that impacts the extended arm to provide power to the actuator wheel assembly.

[0013] Furthermore, it also includes a drive motor, the output shaft of which is connected to a drive worm gear to provide power to the rotary actuator.

[0014] Furthermore, the housing is also provided with a drive shaft, which is powered by a gear and an actuator wheel assembly.

[0015] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. This utility model provides a rotary actuator with an energy storage device. It drives a worm gear to rotate, at which point the electromagnetic clutch is not energized, the actuator wheel assembly is not working, and the energy storage wheel assembly is working. A pawl below the energy storage gear drives a slider to slide in a track, compressing a spring during this process. At the end, the slider is locked by an electromagnet, allowing the energy storage wheel assembly to idle. The electromagnetic clutch is then energized, and the actuator wheel assembly is working. When the control system detects an increased load, the electromagnet releases the energy storage slider. The energy storage slider strikes the extended arm on the actuator gear, helping the actuator wheel assembly overcome the heavy load area, effectively doubling the motor efficiency for a certain period. Furthermore, compared to existing structures, its structure is simpler, lower in cost, and more space-efficient for installation.

[0016] 2. This utility model ingeniously utilizes a gear on each side of the drive worm gear, using only one motor to drive two sets of wheel sets. Furthermore, an electromagnetic clutch at the actuator wheel set end controls its operation, preventing simultaneous power output from both the energy storage wheel set and the actuator wheel set. This fully utilizes the motor while minimizing its load. Attached Figure Description

[0026] In a preferred embodiment, the energy storage wheel assembly 3 includes a second driving helical gear 32, a second transmission gear 33 poweredly connected to the second driving helical gear 32, and an energy storage gear 34 poweredly connected to the second transmission gear 33.

[0027] In a preferred embodiment, the second driving helical gear 32 is poweredly connected to the driving worm gear 1, and the disk 31 is coaxially disposed below the energy storage gear 34.

[0028] Specifically, the energy storage slider 41 is provided with a protrusion, which impacts the extension arm 22 to provide power to the actuator wheel assembly 2.

[0029] Specifically, it also includes a drive motor 11, the output shaft of which is connected to the drive worm gear 1 to provide power to the rotary actuator.

[0030] In a preferred embodiment, the housing 5 is further provided with a drive shaft 52, which is powered by the actuating wheel set 2 via gears. The drive shaft 52 drives the external actuating structure to complete the rotational action.
