Description

Technical Field

[0001] This application relates to the field of switch-related technology, and more specifically, to a retrofit smart switch with a clutch structure. Background Technology

[0002] The word "switch" is defined as turning on and off. It also refers to an electronic component that can open a circuit, interrupt current flow, or divert current to another circuit. The most common type of switch, the control switch, is a human-operated electromechanical device with one or more electronic contacts. A "closed" contact means the electronic contacts are conducting, allowing current to flow; an "open" switch means the electronic contacts are not conducting, forming an open circuit and preventing current from flowing.

[0003] For existing control switches, it is often necessary to open a groove in the wall to install the switch. The surface of the control switch is equipped with a button, which people use to control the state of the switch.

[0004] However, with the advancement of technology and the development of society, people are no longer satisfied with the existing control switches that require manual pressing. Therefore, smart switches were invented. Smart switches replace existing control switches and have a built-in controller that receives wireless signals and controls whether the electronic contacts inside the switch are open or closed based on the wireless signals.

[0005] However, most households already have control switches installed, and replacing them with smart switches is very inconvenient. Summary of the Invention

[0006] In order to overcome at least some of the problems existing in the related technologies, the purpose of this application is to provide a retrofitted smart switch with a clutch structure to solve the problems in the prior art.

[0007] This application provides a retrofitted smart switch with a clutch structure, including a housing connected to a control switch, a controller, a planetary motor fixed in the housing, and a rotating body connected to the planetary motor;

[0008] A swing arm is provided on the outer wall of the rotating body;

[0009] The housing is provided with a first through hole for the swing arm to extend out; when the rotating body is in the first state, the swing arm extends out of the first through hole; when the rotating body is in the second state, the swing arm retracts into the housing.

[0010] The controller is housed inside the housing and connected to the planetary motor, and is used to control the rotation of the planetary motor;

[0011] The rotating body includes a clutch structure; when the clutch structure is in the third state, the rotating body rotates under the drive of the planetary motor, and at the same time, the rotating body drives the swing arm to move; when the clutch structure is in the fourth state, the part of the rotating body that contacts the swing arm rotates under the drive of the swing arm, while the part of the rotating body that contacts the planetary motor remains stationary.

[0012] When an external force pushes the lever, the clutch mechanism is in its fourth state.

[0013] Optionally, the rotating body includes a clutch structure and a switch seesaw;

[0014] The planetary motor drives the switch seesaw to rotate via the clutch structure;

[0015] The switch seesaw contacts the swing arm, causing the swing arm to move.

[0016] Optionally, the clutch structure includes: a motor positioning ring, a clutch spring, and a clutch brake ring;

[0017] The first side of the motor positioning ring is provided with a groove that fits with the rotor of the planetary motor; the motor positioning ring is sleeved on the rotor of the planetary motor through the groove; the second side of the motor positioning ring is provided with a protrusion.

[0018] The clutch brake ring is provided with a second through hole that fits the protrusion; the clutch brake ring is sleeved on the protrusion of the motor positioning ring through the second through hole; a snap-fit ​​protrusion is provided on the side of the clutch brake ring away from the motor positioning ring; the side of the snap-fit ​​protrusion is provided with a slope;

[0019] The clutch spring is disposed between the motor positioning ring and the clutch brake ring, and is sleeved on the protrusion;

[0020] The inside of the switch rocker is provided with a groove that fits the snap-fit ​​protrusion; the switch rocker is sleeved on the clutch brake ring;

[0021] When the clutch structure is in the third state, the clutch spring extends, and the snap-fit ​​protrusion of the clutch brake ring falls into the groove inside the switch rocker, causing the switch rocker to rotate with the clutch brake ring.

[0022] When the clutch structure is in the fourth state, the clutch spring is compressed, and the snap-fit ​​protrusion of the clutch brake ring disengages from the groove inside the switch rocker.

[0023] Optionally, a spring limiting groove is provided on the side of the motor positioning ring and the clutch brake ring that contacts the clutch spring.

[0024] Optionally, the axis of the motor positioning ring, the clutch brake ring, and the switch seesaw is the axis of the planetary motor rotor.

[0025] Optionally, the switch seesaw includes a hollow cylindrical shell; the hollow cylindrical shell encloses the clutch structure.

[0026] Optionally, the hollow cylindrical shell is provided with swing arms on both sides for pushing the swing rod.

[0027] Optionally, a reinforcing rib is provided at the connection between the swing arm and the hollow cylindrical shell.

[0028] Optionally, the protrusion includes: a cylinder and limiting blocks disposed on both sides of the cylinder.

[0029] Optionally, the housing is provided with a rotatable base for fixing the rotating body.

[0030] The technical solution provided in this application may include the following beneficial effects:

[0031] This application provides a retrofitted smart switch with a clutch mechanism. This retrofitted smart switch with a clutch mechanism can be installed on a control switch. The retrofitted smart switch with a clutch mechanism has an internal controller that can accept external control signals to achieve control operations similar to existing smart switches. When the controller receives an external control signal, it controls a planetary motor to rotate, causing a rocker arm to extend out of or retract from the first through hole. Thus, the retrofitted smart switch with a clutch mechanism can receive external control signals and, based on these signals, simulate the operation of pressing a control switch button, achieving intelligent control of various home appliances. In this way, without changing the existing control switches in the home, the retrofitted smart switch with a clutch mechanism achieves the effect of using a smart switch.

[0032] Furthermore, due to the design of the rocker arm, when it extends beyond the first through hole, it may be pressed back into the housing by external force. This could cause the planetary motor to reverse, potentially damaging it. To avoid this damage, the solution provided in this application includes a clutch structure for the rotating body. When the clutch structure is in the third state, the rotating body rotates under the drive of the planetary motor, simultaneously moving the rocker arm. When the clutch structure is in the fourth state, the portion of the rotating body in contact with the rocker arm rotates under the drive of the rocker arm, while the portion in contact with the planetary motor remains stationary. When an external force pushes the rocker arm, the clutch structure remains in the fourth state. This configuration ensures that when an external force pushes the rocker arm, the clutch structure is in the fourth state, at which point the rotating body rotates under the drive of the rocker arm, while the portion in contact with the planetary motor remains stationary, preventing the planetary motor from rotating. This avoids damage to the aftermarket smart switch with a clutch structure caused by the rocker arm being pressed.

[0033] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses or methods consistent with some aspects of this application.

[0043] First, the application scenario of this invention will be explained. Existing control switches often require a recess in the wall for installation, and the surface of the control switch has a button for user control. However, with technological advancements and social development, people are no longer satisfied with the manual pressing control required by existing control switches. Therefore, smart switches were invented to replace existing control switches. Smart switches have an internal controller that receives wireless signals and determines whether the electronic contacts within the switch are open or closed based on these signals. However, most households already have control switches installed, making the replacement with smart switches inconvenient.

[0044] This specific embodiment provides a retrofit smart switch with a clutch structure. When a user wants to replace the existing control switch in their home with a smart switch, they can use the retrofit smart switch with a clutch structure provided in this application. The retrofit smart switch with a clutch structure is installed on the control switch. Through the controller and related mechanical structure inside the retrofit smart switch with a clutch structure, pressing the button on the control switch controls the opening and closing state of the original control switch, thereby controlling the home appliances.

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0046] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations represented in the embodiments below are not limited to those necessary for the solution of the invention described in the claims.

[0047] Example

[0048] refer to Figure 1 and Figure 2 This specific embodiment provides a retrofit smart switch with a clutch structure, including a housing 1 connected to a control switch, a controller 2, a planetary motor 3 fixed in the housing 1, and a rotating body 5 connected to the planetary motor 3;

[0049] A swing arm 4 is provided on the outer wall of the rotating body 5;

[0050] The housing 1 is provided with a first through hole for the swing rod 4 to extend out; when the rotating body 5 is in the first state, the swing rod 4 extends out of the first through hole; when the rotating body 5 is in the second state, the swing rod 4 retracts into the housing 1.

[0051] The controller 2 is housed inside the housing 1 and connected to the planetary motor 3, and is used to control the rotation of the planetary motor 3;

[0052] The rotating body 5 includes a clutch structure; when the clutch structure is in the third state, the rotating body 5 rotates under the drive of the planetary motor 3, and at the same time, the rotating body 5 drives the swing arm 4 to move; when the clutch structure is in the fourth state, the part of the rotating body 5 that contacts the swing arm 4 rotates under the drive of the swing arm 4, while the part of the rotating body 5 that contacts the planetary motor 3 remains stationary.

[0053] When an external force pushes the lever 4, the clutch structure is in the fourth state.

[0054] The aftermarket smart switch with a clutch mechanism provided in this application can be installed on a control switch. The aftermarket smart switch with a clutch mechanism has an internal controller that can accept external control signals to achieve control operations similar to existing smart switches. When the controller receives an external control signal, it controls a planetary motor to rotate, which in turn drives a rotating body to rotate. When the rotating body rotates to the first state, the lever extends out of the first through hole. The control switch button is then pressed. When the rotating body rotates to the second state, the lever retracts from the first through hole. Thus, the aftermarket smart switch with a clutch mechanism can receive external control signals and, based on these signals, simulate the operation of pressing a control switch button, achieving intelligent control of various home appliances. In this way, without changing the existing control switches in the home, the aftermarket smart switch with a clutch mechanism achieves the effect of using a smart switch.

[0055] Furthermore, due to the design of the rocker arm, when it extends beyond the first through hole, it may be pressed back into the housing by external force. This could cause the planetary motor to reverse, potentially damaging it. To avoid this damage, the solution provided in this application includes a clutch structure for the rotating body. When the clutch structure is in the third state, the rotating body rotates under the drive of the planetary motor, simultaneously moving the rocker arm. When the clutch structure is in the fourth state, the portion of the rotating body in contact with the rocker arm rotates under the drive of the rocker arm, while the portion in contact with the planetary motor remains stationary. When an external force pushes the rocker arm, the clutch structure remains in the fourth state. This configuration ensures that when an external force pushes the rocker arm, the clutch structure is in the fourth state, at which point the rotating body rotates under the drive of the rocker arm, while the portion in contact with the planetary motor remains stationary, preventing the planetary motor from rotating. This avoids damage to the aftermarket smart switch with a clutch structure caused by the rocker arm being pressed.

[0056] To facilitate a better understanding of the specific structure and function of the rotating element in the aftermarket smart switch with a clutch mechanism provided in this application, the overall structure of the aftermarket smart switch with a clutch mechanism provided in this application will first be described.

[0057] In practical applications, the control switch button may be a single-point press button or a two-point press button. To enable the aftermarket smart switch with a clutch structure provided in this application to control the two-point press button, the number of the levers 4 can be two; the levers 4 are respectively located on both sides of the rotating body 5. The number of first through holes is also two. When the aftermarket smart switch with a clutch structure is installed on the control switch, the two first through holes correspond to the two pressing points of the button on the control switch. Specifically, the planetary motor can drive the rotating body to rotate clockwise. When the rotating body rotates to the first state, one of the levers extends out of the first through hole, pressing one pressing point of the control switch button. The planetary motor drives the rotating body to rotate counterclockwise, and when the rotating body rotates to the second state, the lever retracts from the first through hole. When the rotating body rotates back to the first state, the lever on the other side extends out of the first through hole (it should be noted that the two white levers correspond one-to-one with the two first through holes. The two first through holes correspond one-to-one with the upper and lower buttons of the button). This presses the other button of the control switch. In this way, the clockwise and counterclockwise rotation of the planetary motor can be used to adjust which of the two buttons on the control switch is pressed.

[0058] It should be noted that the swing arms are respectively located on both sides of the rotating body. Specifically, the swing arms can be directly fixed to both sides of the rotating body, or the swing arms can contact the rotating body through a mechanical structure and move under the drive of the rotating body to extend out of the first through hole or retract into the housing.

[0059] Furthermore, in practical applications, multiple buttons may be installed on the same control switch. To enable a post-installed smart switch with a clutch structure to control multiple buttons on the same control switch, the post-installed smart switch with a clutch structure provided in this application has the following improvements:

[0060] Specifically, in the aftermarket smart switch with a clutch structure, a planetary motor 3, a rotating body connected to the planetary motor 3, and a rocker arm 4 set on the outer wall of the rotating body constitute a mechanical pressing group;

[0061] The aftermarket smart switch with a clutch structure includes multiple mechanical pressing groups.

[0062] With this setup, each mechanical pressing point corresponds to one button. For example, when the control switch has three mechanical buttons with two contacts (upper and lower), the corresponding aftermarket smart switch with a clutch structure can have three mechanical pressing points inside, each used to press one of the mechanical buttons on the control switch.

[0063] Reference Figure 3 The housing 1 includes a bottom shell 11 and an upper shell 12 that is fastened to the bottom shell 11. Specifically, the upper shell 12 is fastened to the bottom shell 11 by a snap fastener.

[0064] This design not only ensures a tight fit between the bottom and top shells but also facilitates disassembly, allowing for inspection of the operation of the various components inside the retrofitted smart switch with its clutch mechanism, thus enabling maintenance.

[0065] Furthermore, the bottom shell 11 is provided with a motor base 13 for fixing the planetary motor 3.

[0066] With this configuration, the planetary motor can be fixed inside the motor base. When the planetary motor is turned on, it will also tend to move under the action of the reaction force. In the solution provided in this application, fixing the planetary motor with the motor base can prevent the planetary motor from moving.

[0067] Furthermore, the aftermarket smart switch with a clutch structure also includes a motor mounting housing 14 that is fastened to the motor base 13 for fixing the planetary motor 3.

[0068] In practical applications, a simple motor base may not be sufficient to completely secure the planetary motor. In this embodiment, the motor mounting housing and the motor base together form a ring structure. That is, the planetary motor is housed within the motor base, and the motor mounting housing is fastened to the motor base and pressed against the bottom shell to secure the planetary motor.

[0069] Furthermore, the controller 2 is a PCBA circuit board with integrated control circuitry.

[0070] It should be noted that the control circuit can refer to the control circuit inside existing smart switches. The main function of the control circuit is to receive control signals and control the rotation of the planetary motor based on these signals. Currently, the circuit for receiving control signals can be a Bluetooth circuit, a WiFi circuit, a 5G or 4G signal circuit, etc.

[0071] Specifically, the material of the shell 1 is plastic.

[0072] The housing 1 is attached to the control switch.

[0073] It should be noted that the aftermarket smart switch with a clutch structure provided in this embodiment can be fixed to the control switch by adhesive bonding or magnetic attachment. However, in practical applications, if magnetic attachment is used, misalignment may occur due to the inherent instability of the magnetic fixation. If misalignment occurs, the first through-hole of the aftermarket smart switch may not correspond to the correct pressing point, preventing the control switch from being pressed correctly. Therefore, this application recommends using a shell bonded to the control switch. Specifically, the bottom shell may have protrusions. These protrusions are bonded to the control switch. This ensures that when the lever is not extended from the bottom shell through the first through-hole, the aftermarket smart switch with a clutch structure will not press the button on the control switch. When the lever extends from the bottom shell through the first through-hole, it can correctly press the button on the control switch and trigger the pressing operation.

[0074] The above content has described the specific working state and function of the aftermarket smart switch with clutch structure provided in this application. Next, the internal clutch structure of the rotating body of the aftermarket smart switch with clutch structure provided in this application and its function will be further explained:

[0075] Reference Figure 4 and Figure 5 The rotating body in the aftermarket smart switch with a clutch structure includes the clutch structure and the switch rocker.

[0076] The planetary motor 3 drives the switch seesaw 54 to rotate through the clutch structure;

[0077] The switch seesaw 54 contacts the swing rod 4, causing the swing rod 4 to move.

[0078] Specifically, the clutch structure includes: a motor positioning ring 51, a clutch spring 52, and a clutch brake ring 53;

[0079] The first side of the motor positioning ring 51 is provided with a groove that fits with the rotor of the planetary motor 3; the motor positioning ring 51 is sleeved on the rotor of the planetary motor 3 through the groove; the second side of the motor positioning ring 51 is provided with a protrusion.

[0080] The clutch brake ring 53 is provided with a second through hole that fits the protrusion; the clutch brake ring 53 is sleeved on the protrusion of the motor positioning ring 51 through the second through hole; the clutch brake ring 53 is provided with a snap-fit ​​protrusion on the side away from the motor positioning ring 51; the side of the snap-fit ​​protrusion is provided with a slope.

[0081] The clutch spring 52 is disposed between the motor positioning ring 51 and the clutch brake ring 53, and is sleeved on the protrusion;

[0082] The inside of the switch rocker 54 is provided with a groove that fits the snap-fit ​​protrusion; the switch rocker 54 is sleeved on the clutch brake ring 53;

[0083] When the clutch structure is in the third state, the clutch spring 52 extends, and the snap-fit ​​protrusion of the clutch brake ring 53 falls into the groove inside the switch rocker 54, causing the switch rocker 54 to rotate with the clutch brake ring 53.

[0084] When the clutch structure is in the fourth state, the clutch spring 52 is compressed, and the snap-fit ​​protrusion of the clutch brake ring 53 disengages from the groove inside the switch rocker 54.

[0085] With this configuration, when the aftermarket smart switch with a clutch mechanism is operating normally, the clutch brake ring is compressed by the clutch spring and pressed against the switch rocker. The locking protrusion of the clutch brake ring falls into the groove of the switch rocker. If the planetary motor rotor rotates, the rotor drives the motor positioning ring to rotate, which in turn drives the clutch brake ring to rotate, which in turn drives the switch rocker to rotate. The switch rocker then drives the swing arm to move.

[0086] In the event of an unexpected situation (including manual pressing of the lever or other external forces squeezing the lever), the lever will move, causing the switch seesaw to move. The switch seesaw will exert a force on the clutch brake ring, causing it to rotate. However, because the part of the switch seesaw and the clutch brake ring directly connected by a slope (i.e., the side of the locking protrusion has a slope), this slope will split the force into two parts: one part will press the clutch brake ring towards the motor positioning ring, and the other part will cause the clutch brake ring to rotate. Since the planetary motor rotor does not rotate, the motor positioning ring cannot rotate; since the motor positioning ring cannot rotate, the clutch brake ring cannot rotate. The movement of the clutch brake ring becomes the compression of the clutch spring, moving towards the motor positioning ring. As the clutch brake ring moves towards the motor positioning ring, the locking protrusion of the clutch brake ring disengages from the groove in the switch seesaw, and the switch seesaw can no longer drive the clutch brake ring to rotate. This avoids the situation where the planetary motor will inevitably rotate when the pendulum moves, and also avoids the situation where the planetary motor is forcibly rotated and damaged when an external force pushes the pendulum to move.

[0087] The rotation of the planetary motor's rotor drives the motor positioning ring to rotate, which in turn drives the clutch brake ring to rotate, which in turn drives the switch seesaw to rotate.

[0088] Furthermore, a spring limiting groove is provided on the side of the motor positioning ring 51 and the clutch brake ring 53 that contacts the clutch spring 52.

[0089] The spring limiting groove prevents the spring from disengaging from its intended position, ensuring the clutch spring functions properly.

[0090] Specifically, the axis of the motor positioning ring 51, the clutch brake ring 53 and the switch seesaw 54 is the axis of the planetary motor 3 rotor.

[0091] The axis of the motor positioning ring, the clutch brake ring, and the switch seesaw is the axis of the planetary motor rotor. This ensures that the planetary motor rotor drives the motor positioning ring, the clutch brake ring, and the switch seesaw to rotate.

[0092] Furthermore, the switch rocker 54 includes a hollow cylindrical housing; the hollow cylindrical housing encloses the clutch structure. This arrangement of the hollow cylindrical housing provides protection for the clutch structure.

[0093] Furthermore, the hollow cylindrical shell is provided with swing arms on both sides for pushing the swing rod 4. Reinforcing ribs are provided at the connection between the swing arms and the hollow cylindrical shell.

[0094] The protrusion of the motor positioning ring 51 includes a cylinder and limiting blocks disposed on both sides of the cylinder. This arrangement ensures that the clutch brake ring 53 can slide up and down on the protrusion of the motor positioning ring 51.

[0095] Specifically, the housing 1 is provided with a rotatable base for fixing the rotating body 5, which is used to rotatably fix the rotating body 5.

[0096] It should be noted that the terms "first" and "second" used in this article are not intended to restrict the specific order, but are merely used to distinguish between different components or functions.
