Description

Power device and swing piece manual-automatic integrated actuator capable of controlling separation
Technical Field
The invention belongs to the technical field of mechanical automation, and particularly relates to a controllable separated power device and swing piece manual-automatic integrated actuator.
Background
There are a large number of rotatable and swingable parts in smart homes and household appliances, such as glass windows, refrigerator doors, rotary shelves, etc. In order to make these components both automatic and compatible with manual operation habits, it is necessary to configure an actuator having a power splitting function. Such actuators are typically large in size and complex in construction, including multiple gear trains and clutches. The clutch device is a core component for realizing mutual switching between two states of power separation and power connection, and the currently applied devices mainly comprise an electromagnetic clutch device and a mechanical clutch device. The electromagnetic clutch device has stable performance, can better realize the function of manual-automatic integrated operation, but has larger energy consumption, is limited by the volume and can not output larger torque. The mechanical clutch device has no extra energy consumption, but has poor clutch effect, and cannot realize seamless switching of manual and automatic integration. In a word, at present, no power supply device with a controllable separation function exists, which can be smoothly switched between automatic operation and manual operation, and can also be miniaturized and lightened.
Taking the chinese invention patent with publication number CN108316802A as an example, the patent discloses a manually operable electric opening and closing actuator for revolving doors, which adopts a planetary gear assembly to cooperate with an electromagnet jaw to realize a manual-automatic integrated function, but when the structure is switched between an electric mode and a manual mode at a high rotation speed, there is a possibility that the electromagnetic jaw and the planetary gear assembly are difficult to separate or engage, which may cause a phenomenon of tooth punching or a delay in switching between manual and automatic functions.
Disclosure of Invention
In view of the above problems in the prior art, the present invention provides a controlled release actuator for a power plant and a swing member that is integrated into a manual-automatic actuator, that has a compact, light and reliable structure, and that can achieve smooth switching between a power connection state and a power release state both in a high-speed operation state and in a low-speed operation state.
A controllable separated power device comprises a gear ring, a planet carrier and a sun gear which are rotatably arranged on the same axis; the planet carrier is provided with a group of planet wheels arranged around the rotation axis of the planet carrier, the planet wheels are meshed with an inner ring gear part arranged on the inner periphery of the gear ring, and the sun wheel is meshed with the planet wheels; the power device also comprises a locked-rotor motor and a locked-rotor worm driven by the locked-rotor motor, wherein the locked-rotor worm is in non-self-locking meshing connection with an external gear ring part arranged on the periphery of the gear ring; in the planet carrier and the sun gear, one end is used as a power input end, the other end is used as a power output end, and the locked-rotor motor is used as a control end to control whether the gear ring can rotate freely or not, so that the power input end and the power output end can be switched between a power separation state and a power connection state in a controllable manner.
The power device with controllable separation can conveniently control and switch the power relation between the power input end and the power output end through the locked-rotor motor. Specifically, when the locked-rotor motor is not powered, the gear ring can rotate freely, the power input end and the power output end are in a power separation state, and the power output end can be forced to rotate by applying small torque to the power output end; when power connection between the power input end and the power output end is needed, the locked-rotor motor is supplied with power to prevent the rotation tendency of the gear ring, and at the moment, the power input end can transmit power to the power output end. Therefore, the device can be controlled to be in a power separation state or a power connection state by controlling the locked-rotor motor, and the locked-rotor motor can be switched between the locked-rotor motor and the locked-rotor motor only by supplying power or cutting off the power, so that the switching process does not involve a mechanical clutch structure, and the switching is very smooth.
Furthermore, the sun gear serves as a power input end, and the planet carrier serves as a power output end; and a power supply unit is arranged at the power input end to drive the sun gear to rotate.
Further, the power supply unit comprises a power motor, a power worm driven by the power motor to rotate, and a power gear coaxially connected with the sun gear; the power worm is meshed with the power gear.
Further, the power gear is a worm gear or a helical gear.
Furthermore, the planet carrier is also coaxially connected with a power output gear.
Furthermore, the tooth profile of the outer tooth ring part is helical teeth or worm teeth, and the lead angle of the locked-rotor worm is larger than the equivalent friction angle so as to ensure non-self-locking matching between the outer tooth ring part and the locked-rotor worm.
Further, when the locked rotor motor executes the locked rotor operation, the working voltage provided for the locked rotor motor is smaller than the rated voltage of the locked rotor motor, so that overcurrent damage of the locked rotor motor is avoided.
A swing piece manual-automatic integrated actuator comprises the power device which can be controlled and separated, an arc rack and a limiting column; the inner side of the arc-shaped rack is provided with a tooth surface and is meshed with the power output gear; the limiting column is arranged on the outer side of the arc-shaped rack and is abutted against the arc-shaped rack so as to ensure that the arc-shaped rack is meshed with the power output gear; the power output gear drives the arc-shaped rack to move in a gap between the power output gear and the limiting column.
The swing piece manual-automatic integrated actuator can drive the swing piece to swing through the arc-shaped rack, for example, a refrigerator door body is driven to rotate, and smooth switching between a manual mode and an automatic mode can be conveniently realized by controlling the locked-rotor motor.
Furthermore, the swing piece manual-automatic integrated actuator also comprises a mounting bracket; the mounting bracket is hinged at one end of the arc-shaped rack so as to be connected with the swinging piece.
Furthermore, the swing piece manual-automatic integrated actuator also comprises a first micro switch and a second micro switch; the arc-shaped rack is also provided with a first convex part and a second convex part; the first microswitch is arranged on the motion track of the first lug boss, and the second microswitch is arranged on the motion track of the second lug boss. When the arc-shaped rack moves to a specific position, the protruding part can trigger the corresponding micro switch to generate a trigger signal, so that the position of the arc-shaped rack can be accurately judged, the angle of the swinging piece can be judged, and a basis is provided for automatic control.
Advantageous effects
The power device with controllable separation can realize the switching between the power separation state and the power connection state by controlling the power supply or the power failure of the locked-rotor motor, and the switching process does not involve mechanical clutch and is quite quiet and smooth.
According to the controllable separated power device provided by the invention, because the greater transmission ratio is formed between the locked-rotor worm and the outer gear ring part, the locked-rotor motor can realize locked rotor only by a small locked-rotor torque, so that the small locked-rotor motor can be used, the working energy consumption is low, and the space and the cost are saved.
The manual-automatic integrated actuator of the swinging piece provided by the invention drives the swinging piece to swing through the arc-shaped rack, can be widely applied to various intelligent household appliances and intelligent household products, can run automatically and can be compatible with manual operation, and the two can be switched smoothly.

Detailed Description
The invention is further illustrated by the following examples, which are intended to illustrate the technical solution of the invention more clearly and are not to be construed as a limitation.
Unless defined otherwise, technical or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item preceding the word comprises the element or item listed after the word and its equivalent, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used only to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
Example 1
A controllable separated power device is shown in figure 1 and comprises a gear ring 1, a planet carrier 2 and a sun gear 3 which are rotatably arranged on the same axis; a group of planet wheels 21 arranged around the rotation axis of the planet carrier 2 are arranged on the planet carrier 2, the planet wheels 21 are meshed with an inner ring gear part 11 arranged on the inner circumference of the gear ring 1, and the sun wheel 3 is meshed with the planet wheels 21; the power device also comprises a locked-rotor motor 4 and a locked-rotor worm 5 driven by the locked-rotor motor 4, wherein the locked-rotor worm 5 is in non-self-locking meshing connection with an outer gear ring part 12 arranged on the periphery of the gear ring 1; in the planet carrier 2 and the sun gear 3, one end is used as a power input end, the other end is used as a power output end, and the locked-rotor motor 4 is used as a control end to control whether the gear ring 1 can rotate freely, so that whether the power input end and the power output end are in a power separation state or a power connection state can be switched in a controllable manner.
The tooth profile of the outer gear ring portion 12 is helical teeth or worm teeth, and in order to ensure that the rotation blocking worm 5 is meshed with the outer gear ring portion 12 in a non-self-locking mode, the lead angle of the rotation blocking worm 5 is larger than the equivalent friction angle of a material. Thus, under the condition that the locked rotor motor 4 is not electrified, the outer gear ring part 12 can rotate freely, and the power input end and the power output end can be in a power separation state.
The locked-rotor motor 4 may be a small motor with low power consumption, so as to achieve a small and light structure. Because the greater transmission ratio is arranged between the locked-rotor worm 5 and the outer gear part 12, the transmission ratio is equal to the number of teeth of the outer gear part 12/the number of the heads of the locked-rotor worm 5, the locked-rotor motor 4 can realize locked rotor only by small locked-rotor torque, the working energy consumption is low, and the space and the cost are saved.
In practice, the structure may be mounted on a fixed support or integrated into a housing so that the components have a carrier to support them in cooperation with each other. For example, the locked-rotor motor 4 is fixed in a housing, and the ring gear 1, the carrier 2, and the sun gear 3 are rotatably mounted in the housing via bearings.
In actual control, when power at the power input end needs to be directly transmitted to the power output end, power is supplied to the locked-rotor motor 4 to prevent the rotation tendency of the gear ring 1, and at the moment, the power input end can directly provide power for the power output end because the gear ring 1 cannot rotate; on the contrary, if the locked rotor motor 4 is not supplied with power, the gear ring 1 can rotate freely, and the power output end can rotate after receiving smaller external force. The power connection state and the power disconnection state can be smoothly switched by controlling the locked-rotor motor 4.
For the setting of locked rotor voltage, if the locked rotor motor 4 is locked rotor under full pressure, the locked rotor motor 4 is easy to burn down due to overcurrent, and the service life of the locked rotor motor 4 is influenced. Therefore, the locked-rotor motor 4 should adopt a power supply mode lower than the rated voltage when the locked-rotor operation is performed. For example, the rated voltage of the locked-rotor motor 4 is 12V, the locking is performed by lowering the voltage, and an appropriate safe voltage, for example, a voltage of 6V or less, etc., can be selected based on the resistance of the motor, the safe current, and the required locked-rotor torque.
Example 2
The controllable separation power device provided by the embodiment is a further improvement of the embodiment 1, specifically as shown in fig. 2 and 3, a sun gear 3 is used as a power input end, and a planet carrier 2 is used as a power output end; a power supply unit is also provided at the power input to drive the sun gear 3 in rotation. The power supply unit comprises a power motor 61, a power worm 62 driven by the power motor 61 to rotate, and a power gear 63 coaxially connected with the sun gear 3; the power worm 62 is engaged with the power gear 63.

In order to facilitate understanding of the installation and use method of the swing piece manual-automatic integrated actuator, the following description will take the example that the swing piece manual-automatic integrated actuator is applied to an intelligent refrigerator and controls the opening and closing of a refrigerator door body. Fig. 5 shows the hinge joint of the refrigerator body and the refrigerator door, and the main body of the swing piece manual-automatic integrated actuator is arranged on the top of the refrigerator body and is generally provided with an outer shell, and the outer shell is omitted in the figure for the convenience of illustrating the internal structure. The mounting bracket 93 of the swing piece manual-automatic integrated actuator is fixed on the refrigerator door body, so that the refrigerator door body is driven to open and close. When the refrigerator door is completely closed, the first protruding portion 911 just contacts the first microswitch 94, and a trigger signal can be generated to determine the position of the refrigerator door, and similarly, when the refrigerator door is completely opened, the second protruding portion 912 contacts the second microswitch 95. When the refrigerator door needs to be automatically opened and closed, the power motor 61 outputs power, the locked rotor motor 4 is electrified to lock the gear ring 1, so that the refrigerator door can be automatically opened and closed, and a control logic framework during automatic operation is shown in fig. 6. When the refrigerator door needs to be opened and closed manually, the locked rotor motor 4 does not supply power, the power motor 61 does not need to supply power, the gear ring 1 can rotate freely at the moment, and the refrigerator door can be opened and closed manually.
