[0001] The present application relates to the technical field of on-off control devices, and in particular to an execution module and an on-off control device. Background Art

[0002] With the development of science and technology, more and more household appliances are gradually entering people's lives. Correspondingly, the use of on-off control devices in household appliances is becoming more and more common. In addition, by combining the on-off control device with smart terminals (such as mobile phones, tablets and notebooks, etc.), users can remotely control the on-off of the circuit of household appliances, making the use of household appliances more convenient.

[0003] In the related art, there are mainly two types of on-off control devices. One type of on-off control device usually adopts a combination of a control board and electronic components to realize the on-off control of the circuit; the other type of on-off control device usually adopts a combination of a control board and a mechanical transmission structure to realize the on-off control of the circuit, which can also be called a mechanical on-off control device.

[0004] Among them, the mechanical on-off control device mainly includes a switch module, an execution module for cooperating with the switch module to realize the on-off of the circuit, and a control board electrically connected to the execution module; wherein the execution module usually includes a motor and an execution member connected to the output shaft of the motor; the control board is electrically connected to the driving member, and the control board can transmit signals with the smart terminal. The above-mentioned on-off control device has a simple structure, but its function is relatively single. Summary of the invention

[0005] In a first aspect, in order to make the functions of a mechanical on-off control device more diverse, the present application provides an execution module.

[0006] An execution module provided in this application adopts the following technical solution:

[0007] An execution module comprises a mounting seat, an execution component connected to the mounting seat and a driving component, wherein the execution component comprises a movable part, an execution part, an elastic maintenance part and an adjustment part;

[0008] The movable member is movably connected to the mounting seat, and the actuator is movably connected to the movable member; the elastic maintaining member is arranged between the movable member and the actuator, and is used to maintain the relative stillness between the actuator and the movable member;

[0009] One end of the adjusting member is provided with a threaded portion threadably connected to the movable member, and the other end is provided with an abutment portion for abutting against a side of the actuator away from the movable member;

[0010] The actuator has an on position and an off position relative to the mounting seat, and the driving assembly is used to drive the movable member to drive the actuator to move between the on position and the off position.

[0011] By adopting the above technical solution, the user can use the intelligent terminal to control the operation of the driving component via the control board, and utilize the elastic maintaining member to maintain the position of the executing member on the movable member, so as to drive the movable member to drive the executing member to move between the on position and the off position, that is, the user can realize the remote control of the switch on and off.

[0012] At the same time, the user also has the need to control the switch on and off proximally. For the convenience of description, it is assumed that the movable member has a first movable position and a second movable position relative to the mounting base; specifically, when the movable member is in the first movable position, the executing member is in the off position, and at this time the switch is in the off state. The user can adjust the position of the executing member relative to the movable member through the adjusting member, so that the executing member moves from the off position to the on position to achieve the purpose of turning on the switch; in addition, the user can also directly apply force to the executing member to make the executing member overcome the elastic force of the elastic maintaining member to realize movement, so as to achieve the point-moving connection of the switch. When the movable member is in the second movable position, the executing member is in the on position and the switch is in the on state. The user can adjust the executing member from the on position to the off position through the adjusting member to achieve the purpose of turning off the switch. To sum up, the execution module of this solution can realize the remote on and off control and proximal on and off control of the switch, and can make the function of the entire mechanical on and off control device more diverse to meet the different needs of users.

[0013] Optionally, the movable member is slidably connected to the mounting base, and the driving component is used to drive the movable member to move linearly.

[0014] By adopting the above technical solution, the movable member is slidably connected to the mounting base, so that the movable member realizes position movement by sliding after being driven, making the movement track of the movable member simpler.

[0015] Optionally, the executing member is slidably connected to the movable member, and the elastic maintaining member is a linear spring; a guide rod is provided between the executing member and the movable member, and the linear spring is sleeved on the guide rod.

[0016] By adopting the above technical solution, the guide rod is used to realize the slidable connection between the executing member and the movable member, making the movement track of the executing member relative to the movable member simpler and facilitating the movement of the executing member to be more stable; correspondingly, the linear spring is ejected on the guide rod, which can reduce the situation that the linear spring is deformed excessively after being stressed and reduce its normal service life.

[0017] Optionally, one end of the executing member is rotatably connected to the movable member, and an arc-shaped guiding member for guiding the executing member is provided on the movable member; the abutting portion abuts on the area between the hinged end and the free end of the executing member, and the elastic maintaining member is a torsion spring provided at the hinge joint of the executing member and the movable member.

[0018] By adopting the above technical solution, rotatably connecting one end of the actuator to the movable member enables the actuator to swing relative to the movable member; when the moving stroke required to control the on / off of the actuator with the adjusting member is fixed, compared with the actuator moving linearly, the adjusting stroke required for the adjusting member in this solution is shorter, making the proximal control more convenient.

[0019] Optionally, at least two sliding guides are provided on the mounting base along the sliding direction of the movable member, and the movable member is provided with a sliding sleeve that cooperates with the sliding guides.

[0020] By adopting the above technical solution, the sliding connection between the movable member and the mounting base is conveniently realized by the arrangement of the sliding guides, and the number of the sliding guides is at least two, which can maintain the stability of the movable member during the sliding process.

The servo motor is arranged on the mounting base, the gear is arranged on the output shaft of the servo motor, the rack is arranged on the movable member and the length direction of the rack is parallel to the sliding direction of the movable member, and the rack meshes with the gear.

[0022] By adopting the above technical solution, the servo motor drives the gear to rotate, and by using the meshing between the gear and the rack, the purpose of driving the movable member to slide can be achieved. The overall structure is simple and the transmission stability is high.

[0023] Optionally, the driving assembly includes a linear cylinder connected to the mounting base and a guide post arranged on the telescopic rod of the linear cylinder. The movable member is provided with an inclined guide groove for the guide post to extend into.

[0024] By adopting the above technical solution, the linear cylinder drives the guide post to move linearly, and by using the cooperation between the guide post and the inclined guide groove, the purpose of driving the movable member to slide relative to the mounting base can be achieved. The overall structure is simple and practical.

[0025] In a second aspect, in order to make the functions of the mechanical on / off control device more diverse, the present application provides an on / off control device.

[0026] The on / off control device provided by the present application adopts the following technical solution:

[0027] An on / off control device includes a switch module and a control board, and also includes one of the above-mentioned actuator modules. The control board is electrically connected to the driving assembly.

[0028] By adopting the above technical solution, the user can realize the remote on / off control and proximal on / off control of the switch, which is convenient to meet the different needs of the user.

[0029] Optionally, the switch module includes a first power connection component and a second power connection component. Both the first power connection component and the second power connection component are used for power connection. The first power connection component is relatively fixed to the mounting base, and the second power connection component is relatively fixed to the actuator.

[0030] By adopting the above technical solution, fixing the second power connection component to the actuator enables the second power connection component to move with the actuator, so that the first power connection component and the second power connection component can come into contact or separate, achieving the purpose of connecting or disconnecting the switch module.

[0031] Optionally, the switch module includes a fixed power connection component, a movable power connection component, and a normally open elastic member. Both the fixed power connection component and the movable power connection component are used for power connection, and the movable power connection component has a disconnected position and a connected position relative to the fixed power connection component; the normally open elastic member is used to maintain the movable power connection component in the disconnected position, and the actuator is used to push the movable power connection component to move from the disconnected position to the connected position.

[0032] By adopting the above technical solution, the setting of the normally open elastic member in the switch module can keep the switch module in the normally open state when it is not affected by external forces. Driving the movable power connection component to contact the fixed power connection component with the actuator can achieve the function of connecting the switch module. In this solution, the switch module and the actuator module are two relatively independent modules in structure, which is convenient for the adaptation and assembly of the on-off control device.

[0042] The following further elaborates on this application with reference to the accompanying drawings.

[0043] The mechanical on-off control device mainly includes a switch module, an execution module for cooperating with the switch module to achieve circuit on-off, and a control board electrically connected to the execution module; among them, the execution module usually includes a motor and an executing part 22 connected to the output shaft of the motor; the control board is electrically connected to the driving part, and the control board can transmit signals with the intelligent terminal.

[0044] The embodiment of this application discloses an execution module.

[0045] Embodiment 1

[0046] Refer to Figure 1 and Figure 2 An execution module includes a mounting base 1, an execution component 2 movably connected to the mounting base 1, and a driving component 3. Among them, the mounting base 1 is relatively fixed to the switch module, and the driving component 3 is electrically connected to the control board, so that the user can drive the execution component 2 to move relative to the mounting base 1 through the circuit board via the intelligent terminal; and by using the cooperation between the execution component 2 and the switch module, the purpose of remotely controlling the on-off of the switch is achieved.

[0047] Specifically, the execution component 2 includes a movable part 21, an executing part 22, an elastic maintaining part 23, and an adjusting part 24. Among them, both the movable part 21 and the executing part 22 are in block shape, and the movable part 21 is movably connected to the mounting base 1, and the executing part 22 is movably connected to the movable part 21; correspondingly, the elastic maintaining part 23 is used to maintain the relative static state between the executing part 22 and the movable part 21, and the adjusting part 24 is used to adjust the position between the executing part 22 and the movable part 21.

[0048] At the same time, the executing part 22 has a closed position and an open position relative to the mounting base 1, and the driving component 3 is used to drive the movable part 21 to drive the executing part 22 to move between the closed position and the open position, so as to achieve the purpose of remotely controlling the on-off of the switch. And the adjusting part 24 can be used to adjust the position of the executing part 22 relative to the movable part 21, that is, it can also move the executing part 22 between the closed position and the open position, and can achieve the purpose of proximally controlling the on-off of the switch.

[0049] In this solution, the actuator 22 is used to cooperate with the corresponding structure in the switch module to achieve the purpose of switching on the switch. In addition, in order to facilitate the cooperation between the actuator 22 and the switch module, a protruding switch contact 222 is formed at one end of the actuator 22 close to the switch module.

[0050] In this embodiment, the movable member 21 is slidably connected to the mounting seat 1, and the actuator 22 is slidably connected to the movable member 21; at the same time, the sliding direction of the movable member 21 is consistent with the sliding direction of the actuator 22. Specifically, a movable notch 11 is formed on the mounting seat 1, and the movable member 21 extends into the movable notch 11; at least two sliding guides 12 are fixed on the mounting seat 1, and the sliding guides 12 are all in the movable notch 11, and the length direction of the sliding guides 12 is the same as the sliding direction of the movable member 21; accordingly, a sliding hole corresponding to the position of the sliding guide 12 is opened on the movable member 21 in the movable notch 11, and a sliding sleeve 211 that slides with the sliding guide 12 is fixedly installed in the sliding hole.

[0051] In this embodiment, the sliding guide member 12 can be a circular guide rod; in another embodiment, the sliding guide member 12 can also be a guide rail. Accordingly, through the cooperation between the sliding guide member 12 and the sliding sleeve 211, the sliding connection between the movable member 21 and the mounting seat 1 can be achieved.

[0052] The adjusting member 24 is fixedly connected to the movable member 21. Specifically, the adjusting member 24 includes a rod body 241, a threaded portion 242, and an abutting portion 243. The rod body 241 is in the shape of a long cylindrical strip. Accordingly, a through hole 221 is provided on the actuator 22 for the rod body 241 to pass through. In this embodiment, there are two rod bodies 241, and the through hole 221 is adapted to the rod body 241. The sliding connection between the actuator 22 and the movable member 21 can be achieved through the guiding effect of the two rod bodies 241.

[0053] At the same time, the threaded portion 242 is formed at one end of the rod body 241, and the threaded portion 242 is threadedly connected to the movable part 21, so as to achieve relative fixation between the adjusting part 24 and the movable part 21; the abutment portion 243 is formed at the other end of the rod body 241, and the abutment portion 243 is used to abut against the side of the actuator 22 away from the adjusting part 24, and the length direction of the adjusting part 24 is consistent with the sliding direction of the actuator 22.

[0054] The elastic maintaining member 23 is installed between the movable member 21 and the actuating member 22. In this embodiment, the elastic maintaining member 23 is a linear spring. The number of linear springs is the same as the number of adjusting members 24, and the linear springs are sleeved on the rod bodies 241 of the adjusting members 24 in a one-to-one correspondence. At the same time, one end of the linear spring abuts against the movable member 21, and the other end abuts against the actuating member 22. And in this embodiment, the surfaces of the movable member 21 and the actuating member 22 for the linear spring to abut against are also provided with limiting sunk grooves 25 for accommodating the ends of the linear springs.

[0055] The driving assembly 3 is used to drive the movable member 21 to move. In this embodiment, the driving assembly 3 includes a servo motor 31, a gear 32 and a rack 33. Among them, the servo motor 31 is fixedly installed on the mounting base 1, the gear 32 is fixedly sleeved on the output shaft of the servo motor 31, and the rack 33 is formed on the movable member 21 and the length direction of the rack 33 is consistent with the sliding direction of the movable member 21. At the same time, the gear 32 meshes with the rack 33, so that the effect of driving the movable member 21 to move can be achieved through the servo motor 31.

[0056] The implementation principle of an actuating module in an embodiment of the present application is as follows:

[0057] The user can use an intelligent terminal to control the operation of the servo motor 31 via the control board to achieve the purpose of remotely controlling the on / off of the switch; at the same time, the user can also achieve the purpose of proximally controlling the on / off of the switch through the position adjustment function of the adjusting member 24 on the actuating member 22.

[0058] For the convenience of description, it is assumed that the movable member 21 has a first active position and a second active position relative to the mounting base 1; specifically, the servo motor 31 can drive the movable member 21 to move between the first active position and the second active position, and due to the action of the linear spring, the position of the actuating member 22 can remain relatively stationary with respect to the movable member; thus, the driving action of the servo motor 31 can be used to drive the actuating member 22 to move, so that the user can remotely control the on / off of the switch.

[0059] At the same time, when the movable member 21 is in the first active position, the actuating member 22 is in the off position, and the switch is in the off state at this time. The user can adjust the position of the actuating member 22 relative to the movable member 21 through the adjusting member 24, so that the actuating member 22 moves from the off position to the on position to achieve the purpose of turning on the switch. In addition, the user can also directly apply a force to the actuating member 22 to make the actuating member 22 overcome the elastic force of the elastic maintaining member 23 to move, so as to achieve the point-by-point turning on of the switch.

[0060] When the moving part 21 is in the second moving position, the actuator 22 is in the on position. At this time, the switch is in the on state. The user can move the actuator 22 in the direction close to the off position through the adjusting part 24 to achieve the purpose of turning off the switch. In addition, if the driving component 3 or the control board fails, the user can also achieve the proximal control of the switch on and off through the adjusting part 24.

At the same time, the guide post 35 is fixedly installed on the telescopic rod of the linear cylinder body 34, and the guide post 35 is a cylinder perpendicular to the telescopic rod of the linear rod body 241; correspondingly, an inclined guide groove 212 for the guide post 35 to extend into is formed on the moving part 21, and the projection distance between the two ends of the inclined guide groove 212 in the moving direction of the moving part 21 is not less than the moving distance of the moving part 21.

[0063] The linear cylinder body 34 drives the guide post 35 to move linearly. By using the cooperation between the guide post 35 and the inclined guide groove 212, the purpose of driving the moving part 21 to slide relative to the mounting seat 1 can be achieved.

By driving the driving component 3 to drive the actuator 22 to move and using the cooperation between the actuator 22 and the switch module, the purpose of controlling the switch channel can be achieved.

[0067] In this embodiment, the switch module includes a first power connection member and a second power connection member. Among them, both the first power connection member and the second power connection member are used for power connection. The first power connection member is fixedly connected to the mounting base 1, and the second power connection member is fixedly connected to the actuator 22. The second power connection member can move along with the actuator 22, so that the first power connection member and the second power connection member can contact or separate, achieving the purpose of turning on or off the switch module.

Among them, both the fixed power connection member and the movable power connection member are used for power connection, and the movable power connection member has a disconnected position and a connected position relative to the fixed power connection member. At the same time, the normally open elastic member is used to maintain the movable power connection member in the disconnected position, and the actuator 22 is used to push the movable power connection member to move from the disconnected position to the connected position.
