Background

The words switch are to be interpreted as open and closed. It also refers to an electronic component that can open a circuit, interrupt a current, or cause it to flow to other circuits. The most common switches, i.e. control switches, are electromechanical devices operated by a person, in which there are one or several electrical contacts. The "closing" of a contact means that the electronic contact is conductive, allowing current to flow; an "open" opening of the switch means that the electrical contact is not conductive, creating an open circuit, not allowing current to flow.

the outer side wall of the rotor 5 is provided with a swing rod structure 4;

a through hole for the swing rod structure 4 to extend out is formed in the shell 1; when the rotating body 5 is in a first state, the swing rod structure 4 extends out of the through hole; when the rotor 5 is in the second state, the swing rod structure 4 is retracted into the shell 1;

the controller 2 is arranged in the shell 1, is connected with the planetary motor 3 and is used for controlling the planetary motor 3 to rotate;

the swing link structure 4 comprises a lever 41;

the distance between the contact force-receiving point of the lever 41 and the rotor 5 and the fulcrum of the lever 41 is greater than the distance between the contact force-receiving point of the lever 41 and the control switch and the fulcrum of the lever 41;

the rotor 5 drives the lever 41 to press the switch.

The afterloading intelligence switch based on lever principle that this application provided can install on control switch. A controller is arranged in the rear-mounted intelligent switch based on the lever principle, and the controller can receive an external control signal to achieve control operation similar to that of the existing intelligent switch. When the controller receives an external control signal, the planetary motor can be controlled to rotate, and the rotation of the planetary motor can drive the rotating body to rotate. When the rotor rotates to the first state, the swing rod structure extends out of the through hole. A button of the control switch is pressed. When the rotor rotates to a second state, the swing rod structure retracts from the through hole. Therefore, the lever principle-based rear-mounted intelligent switch can receive an external control signal, simulate the operation of pressing a button of the control switch based on the external control signal, and achieve the purpose of intelligently controlling each electric appliance in a house. Therefore, on the basis of not changing the original control switch in a house, the effect of using the intelligent switch is achieved through the rear-mounted intelligent switch based on the lever principle.

Further, referring to fig. 4 and 5, a fixed column is arranged at the fulcrum position of the lever 41; the lever 41 is rotatably fixed to the housing 1 via the fixing post. By the arrangement, a supporting point which can be relied on can be provided for the supporting point position.

Specifically, the housing 1 includes: the lever 41 fixes the case 15; the lever 41 fixing shell 15 comprises two sub-lever 41 fixing shells 15 which are symmetrical left and right; each sub-lever 41 fixing shell 15 is provided with a through hole matched with the lug of the fixing column, and the through hole is used for fixing the lever 41. The housing 1 includes: the lever 41 is used for placing the lever 41 fixing shell 15 base.

Such an arrangement may not only provide a fulcrum for the lever 41. And the assembly process is more convenient. The lever 41 and the lever 41 fixing shell 15 are assembled first, and then the assembled lever 41 fixing shell 15 is placed on the base of the lever 41 fixing shell 15.

In practical applications, the button of the control switch may be a button of a single-point pressing type, or may be a button of an upper-lower two-point pressing type. In order to enable the afterloading intelligent switch based on the lever principle to control the two-point pressing type button. The number of the swing rod structures 4 can be two; the swing rod structures 4 are respectively arranged on two sides of the rotating body 5. The number of through holes is also two. When the rear-mounted intelligent switch based on the lever principle is arranged on the control switch, the positions of the two through holes corresponding to the control switch are upper and lower pressing points of a button on the control switch. Specifically, the planetary motor can drive the rotor to rotate clockwise, and when the rotor rotates to the first state, the through hole is stretched out to the pendulum rod structure of one side. One pressing point of the button of the control switch is pressed. The planetary motor drives the rotating body to rotate clockwise and anticlockwise, and the swing rod structure is retracted from the through hole when the rotating body rotates to the second state. When the rotor rotates to the first state again, the swing rod structure on the other side extends out of the through hole (it needs to be explained that the two white rods correspond to the two through holes one by one, and the two through holes correspond to the upper pressing point and the lower pressing point of the button one by one) to press the other pressing point of the button of the control switch. In this way, it is possible to control which of the two pressing points of the push button on the switch is pressed, by adjusting the clockwise rotation and the counterclockwise rotation of the planetary motor.

It should be noted that the swing link structures are respectively arranged on two sides of the rotating body. Specifically, the swing rod structure can be directly fixed on two sides of the rotor, and the swing rod structure can also be in contact with the rotor through a mechanical structure and move under the driving of the rotor to extend out of the through hole or retract into the shell.

Further, the rotating body 5 comprises a switch seesaw; a swing arm is arranged on the side surface of the switch seesaw; the swing arm drives the lever 41 to move.

The swing link structure 4 further includes: the elastic member 42;

one end of the elastic member 42 is fixed on the housing 1, and the other end presses the lever 41, so that the lever 41 is attached to the swing arm.

In practical application, the swing arm can only drive the lever to move towards one direction, so that the lever is driven to press the button on the control switch to operate. When the swing arm moves to the other direction, the lever does not follow the movement of the swing arm, thereby retracting. In the scheme provided by the application. Through the arrangement of the elastic piece. So that one side of the lever is pressed against the swing arm by the elastic member. So set up, when the swing arm moved to another direction, the lever can be under the extrusion of elastic component, moves along with the swing arm, reaches the effect of withdrawing.

Specifically, the elastic member 42 is a torsion spring. The torsion spring is sleeved on the fixing column.

Further, the lever 41 includes flat power and resistance arms and a spindle-shaped fulcrum reinforcement structure.

The spindle-shaped fulcrum reinforcing structure can ensure the mechanical strength of the fulcrum and avoid damage caused by too large stress. When the elastic component is the torsional spring, because the restriction in space, the lever need give way the position for the torsional spring. The fixing column of the lever is relatively narrow and needs to be reinforced by a spindle-shaped fulcrum.

Further, in practical applications, a plurality of buttons may be disposed on the same control switch. In order to enable a rear-mounted intelligent switch based on the lever principle to control a plurality of buttons on the same control switch. The utility model provides a back-loading intelligence switch based on lever principle has still made following improvement:

specifically, in the lever principle-based after-loading intelligent switch, one planetary motor 3, one rotating body connected with the planetary motor 3 and a swing rod structure 4 arranged on the outer side wall of the rotating body form a group of mechanical pressing groups; wherein, the outer side wall of a rotor can be provided with one or two swing link structures.

The lever principle-based afterloading intelligent switch comprises a plurality of mechanical pressing groups.

So set up, each mechanical department of pressing corresponds to a button. For example: when the control switch is provided with three mechanical buttons with upper and lower contacts, three mechanical pressing positions can be arranged in the corresponding lever principle-based rear-mounted intelligent switch and are respectively used for pressing the mechanical buttons on the control switch.

Referring to fig. 3, the housing 1 includes a bottom case 11 and an upper case 12 snap-fitted to the bottom case 11. Specifically, the upper case 12 is fastened to the bottom case 11 by a snap.

So set up, drain pan and epitheca not only can closely be fixed, still convenient to detach to look over the operational aspect of the inside each device of back dress intelligence switch based on lever principle so that maintain it.

Further, a motor base 13 for fixing the planetary motor 3 is disposed on the bottom case 11.

So set up, the planetary motor can be fixed in motor base, and when the planetary motor clicked the operation, planetary motor self also can have the trend of removal under the effect of reaction force, and in the scheme that this application provided, can avoid the planetary motor to remove through the fixed planetary motor of motor base.

Further, the afterloading intelligence switch based on lever principle still includes: and a motor fixing shell 14 buckled on the motor base 13 and used for fixing the planetary motor 3.

In practical application, a simple motor base may not be capable of completely fixing the planetary motor. In the scheme provided by the embodiment, the motor fixing shell and the motor base can jointly form an annular structure. Namely: the planetary motor is located in the motor base, and the motor fixing shell is buckled on the motor base and extrudes and fixes the planetary motor to the bottom shell.

Further, the controller 2 is a PCBA circuit board integrated with a control circuit.

It should be noted that the control circuit may refer to a control circuit inside an existing intelligent switch. The main functions realized by the control circuit are as follows: receiving the control signal controls rotation of the planetary motor based on the control signal. The circuit for receiving the control signal at present can be a Bluetooth circuit, a Wi-Fi circuit, a 5G or 4G signal circuit and the like.

Specifically, the shell 1 is made of plastic.

The housing 1 is bonded to the control switch.

It should be noted that. The after-loading intelligent switch based on the lever principle can be fixed on the control switch in an adhesion mode and can also be fixed on the switch in a magnetic type mode. However, in practical applications, if the magnetic-type fixing method is adopted to fix the rear-mounted intelligent switch to the switch, the magnetic-type fixing method is not very firm, so that a problem of misalignment may occur, and if the rear-mounted intelligent switch based on the lever principle is misaligned, the through hole of the rear-mounted intelligent switch based on the lever principle may not correspond to a correct pressing point, and the rear-mounted intelligent switch based on the lever principle may not be able to correctly press the control switch. The solution provided by the present application suggests the use of a housing glued to the control switch. Specifically, the bottom shell may be provided with a protrusion thereon. Each protrusion is bonded to the control switch. When the swing rod structure does not extend out of the bottom shell through the first through hole, the rear-mounted intelligent switch based on the lever principle cannot press a button on the control switch. When the swing rod structure extends out of the bottom shell through the first through hole, the swing rod structure can correctly press a button on the control switch and trigger the button to perform pressing operation.
