Description

Technical Field

[0001] This application relates to the technical field of electrical equipment, and particularly to an electric switch. Background Art

[0002] An electric switch is an electrical device used to control the on / off of a circuit. Electric switches are widely used in various fields, such as valve control systems, electric vehicle charging ports, and electronic products. Inside the electric switch, there are a moving contact and a static contact. By controlling the closing or separation of the moving contact and the static contact, the on / off of the circuit can be controlled.

[0003] In the prior art, a very large number of switches often need to be set up during actual use. During the operation of a large number of switches, excessive human and material resources will be occupied. Therefore, there is an urgent need for an electric switch to save the human and material costs during use. Utility Model Content

[0004] This application provides an electric switch to save the human and material costs during use.

[0005] In a first aspect, this application provides an electric switch, including a housing, a moving contact group, a first static contact, a second static contact, a third static contact, and a motor. The housing includes a base. The moving contact group is movably arranged inside the base.

[0006] The first static contact includes a first terminal, a first conducting end, and a second conducting end. The first terminal is arranged outside the base and is used for electrically connecting to an external power source or load. The first conducting end and the second conducting end are arranged inside the base. The second static contact includes a second terminal and a third conducting end. The second terminal is arranged outside the base and is used for electrically connecting to an external power source or load. The third conducting end is arranged inside the base. The third static contact includes a third terminal and a fourth conducting end. The third terminal is arranged outside the base and is used for electrically connecting to an external power source or load. The fourth conducting end is arranged inside the base.

[0007] The output shaft of the motor is connected to the moving contact group. The motor drives the moving contact group to move, so that the moving contact group simultaneously contacts the first conducting end and the third conducting end, thereby conducting the first static contact and the second static contact through the moving contact group. Or, the motor drives the moving contact group to move, so that the moving contact group simultaneously contacts the second conducting end and the fourth conducting end, thereby conducting the first static contact and the third static contact through the moving contact group.

[0008] Through the above solution, this application drives the movement of the moving contact group by using a motor, which is more convenient compared to the traditional method of pressing a switch using manual operation, avoiding the problem of requiring a large amount of manpower to operate these switches due to an excessive number of switches during use, and saving the use of human resources during use.

[0009] Moreover, this application provides a first static contact, a second static contact, and a third static contact. When the motor drives the moving contact group to move so that both the first static contact and the second static contact are in contact with the moving contact group, the first set of circuits connected to the electric switch is turned on. When the motor drives the moving contact group to move so that both the first static contact and the third static contact are in contact with the moving contact group, the second set of circuits connected to the electric switch is turned on. With this arrangement, the electric switch can control the on / off of two sets of circuits simultaneously through the motor, thus saving the installation of one electric switch and achieving the purpose of saving material costs during use.

[0010] In a possible design, the moving contact group includes a moving contact bridge and a rotating shaft. The moving contact bridge is fixedly connected to the rotating shaft. A first moving contact is provided at the first end of the moving contact bridge, and a second moving contact is provided at the second end of the moving contact bridge. Both the first conduction end and the second conduction end are located on the rotation path of the first moving contact. Both the third conduction end and the fourth conduction end are located on the rotation path of the second moving contact. The motor drives the rotating shaft to rotate, causing the first moving contact to contact the first conduction end while the second moving contact contacts the third conduction end. Alternatively, the motor drives the rotating shaft to rotate, causing the first moving contact to contact the second conduction end while the second moving contact contacts the fourth conduction end.

[0011] Through the above solution, in this application, the moving contact group is arranged to be rotatably connected to the base. The rotation of the rotating shaft can be used to drive the moving contact bridge to rotate, so that the first moving contact contacts the first conduction end while the second moving contact contacts the third conduction end, or the first moving contact contacts the second conduction end while the second moving contact contacts the fourth conduction end. The rotation of the motor is used to drive the rotating shaft to rotate, thereby driving the moving contact bridge to rotate, and thus the purpose of simultaneously controlling the conduction or disconnection of two circuits by one electric switch can be achieved.

[0012] In a possible design, the electric switch includes a first microswitch and a second microswitch. Both the first microswitch and the second microswitch are electrically connected to the motor. The first microswitch is used to control the motor so that the first moving contact contacts the first conduction end while the second moving contact contacts the third conduction end. The second microswitch is used to control the motor so that the first moving contact contacts the second conduction end while the second moving contact contacts the fourth conduction end.

[0013] Through the above solution, this application can use the first microswitch and the second microswitch to control the rotation of the motor, thereby controlling the movement of the moving contact group. Compared with manually controlling the opening and closing of the motor on-site, both the first microswitch and the second microswitch can be connected to a signal receiver, and with the cooperation of a signal generator, remote control of the electric switch for line switching or on / off can be achieved. In this way, the operation of the electric switch can be made more convenient.

[0014] In a possible design, the shell further includes a middle cover, which is arranged on the base. A driving assembly is provided on the side of the middle cover facing away from the base, the output shaft of the motor is connected to the driving assembly, a driving part is provided on the side of the driving assembly facing the middle cover, the rotating shaft is provided with a driven part, and the driving part passes through the middle cover and is connected to the driven part. The driving assembly is provided with a first protrusion and a first groove. When the first microswitch controls the motor to rotate, the start button of the first microswitch is located in the first groove, and the start button of the second microswitch abuts against the first protrusion. Alternatively, when the second microswitch controls the motor to rotate, the start button of the first microswitch abuts against the first protrusion, and the start button of the second microswitch is located in the first groove.

[0015] Through the above scheme, when the start button of the first micro switch is located in the first groove, the motor cannot be controlled by the first micro switch, and when the start button of the second micro switch is located in the first groove, the motor cannot be controlled by the second micro switch. In this way, the rotation of the motor can be restricted. It avoids the possibility of the moving contact group being driven by the motor to move due to the start button of the motor being touched by mistake, thereby causing the position of the moving contact group to shift, causing the circuit to be disconnected or causing the moving contact group to be damaged, thereby increasing the reliability of the use of the electric switch and also increasing the service life of the moving contact group.

[0016] In a possible design, the driving assembly includes a first gear, and the first protrusion and the first groove are both disposed on the first gear.

[0017] Through the above scheme, because the first gear has the advantages of constant transmission ratio, wide application range and easy maintenance, the driving component is configured as the first gear. Both the early installation process and the later maintenance are relatively simple, and the rotation of the first gear is relatively stable, which can increase the reliability of the use of the electric switch.

[0018] In a possible design, the electric switch further includes a third microswitch and a first indicator light, the third microswitch is electrically connected to the first indicator light, and the drive assembly is further provided with a second protrusion and a second groove. When the first static contact is connected to the second static contact, the start button of the third microswitch abuts against the second protrusion, and the third microswitch controls the first indicator light to light up. When the start button of the third microswitch is located in the second groove, the third microswitch controls the first indicator light to turn off. And / or, the electric switch further includes a fourth microswitch and a second indicator light, the fourth microswitch is connected to the second indicator light, and the drive assembly is further provided with a third protrusion and a third groove. When the first static contact is connected to the third static contact, the start button of the fourth microswitch abuts against the third protrusion, and the fourth microswitch controls the second indicator light to light up. When the start button of the fourth microswitch is located in the third groove, the fourth microswitch controls the second indicator light to turn off.

[0019] Through the above solution, a third microswitch and a fourth microswitch are arranged in the electric switch of the present application. The third microswitch is connected to the first indicator light, and the fourth microswitch is connected to the second indicator light. During the process that the driving component rotates to drive the moving contact group to rotate, the second protrusion can cooperate with the second groove and the start button of the third microswitch, and the third protrusion can cooperate with the third groove and the start button of the fourth microswitch to control the lighting or extinguishing of the first indicator light and the second indicator light.

[0020] Moreover, the first protrusion and the second groove on the driving component also cooperate with the first microswitch and the second microswitch. In this way, when the driving component rotates to drive the first static contact and the second static contact to conduct, the first indicator light can light up to indicate that one of the paths has been conducted. When the driving component rotates to drive the first static contact and the third static contact to conduct, the second indicator light can light up to indicate that the other path has been conducted. In this way, the user can clearly recognize the conduction and disconnection of a certain path without spending more time to judge, saving the labor cost during the use process.

[0021] In a possible design, the driving component further includes a second gear and a third gear. The second protrusion and the second groove are both arranged on the second gear, and the third protrusion and the third groove are both arranged on the third gear.

[0022] Through the above solution, the second protrusion and the second groove are arranged on the second gear, and the third protrusion and the third groove are arranged on the third gear, so that the first gear, the second gear and the third gear mesh with each other. In this way, on the basis of not affecting the cooperation between the second protrusion and the second groove and the third microswitch, and the cooperation between the third protrusion and the third groove and the fourth microswitch, the functions of the first gear are dispersed. It is not necessary to arrange all the first protrusion, the first groove, the second protrusion, the second groove, the third protrusion and the third groove on the first gear, increasing the error tolerance rate of the first gear during the use process, thereby increasing the error tolerance rate of the electric switch during the use process and improving the use reliability of the electric switch.

[0023] In a possible design, the base is provided with a first limiting structure, and the first limiting structure is located on the rotation path of the first end. The first limiting structure is used to limit the position of the first end. And / or, the base is provided with a second limiting structure, and the first limiting structure is located on the rotation path of the second end. The second limiting structure is used to limit the position of the second end.

[0024] Through the above solution, the first limiting structure and the second limiting structure are arranged in the base, and the movement of the first end and the second end can be limited. When the first moving contact touches the first conducting end or the second conducting end, the arrangement of the first limiting structure can reduce the probability of the problem that the first moving contact breaks contact with the first conducting end or the second conducting end due to excessive movement of the first end. When the second moving contact touches the third conducting end or the fourth conducting end, the arrangement of the second limiting structure can reduce the probability of the problem that the second moving contact breaks contact with the third conducting end or the fourth conducting end due to excessive movement of the second end. In this way, the reliability of the electric switch in use can be increased.

[0025] In a possible design, a third limiting structure is provided on the side of the middle cover facing the base, and a matching structure adapted to the third limiting structure is provided on the rotating shaft. The middle cover covers the base, and the third limiting structure and the matching structure cooperate to limit the rotation of the rotating shaft.

[0026] Through the above solution, in the present application, a third limiting structure is provided on the side of the middle cover facing the base, and a matching structure is provided on the side of the rotating shaft facing the middle cover. The third limiting structure and the matching structure can be used to cooperate to limit the rotation of the rotating shaft, increasing the reliability of the electric switch in use.

[0027] In a possible design, the electric switch further includes an upper cover, and the upper cover is provided with a handle operation hole, and the position of the handle operation hole corresponds to that of the driving component. The handle operation hole is used for an external handle to pass through to operate the driving component.

[0028] Through the above solution, when the motor fails and cannot control the movement of the moving contact group, the handle can also be used to pass through the handle operation hole to control the operating component so that the moving contact component can move. In this way, it can play a role in ensuring the use of the electric switch and increasing the reliability of the electric switch in use. Description of the Drawings

Figure 3 It is a schematic diagram of the internal structure of the electric switch provided for the embodiment of this application in a state where one path is connected.Figure 4 Schematic diagram of the internal structure of the electric switch provided by the embodiment of the present application in the connected state of another path. Figure 5 Schematic diagram of the structure of the first static contact, the second static contact and the third static contact provided by the embodiment of the present application.

[0061] As Figures 1 to 5 As shown, the present application provides an electric switch, which includes a housing 100, a moving contact group 200, a first static contact 300, a second static contact 400, a third static contact 500 and a motor 600. The housing 100 includes a base 110. The moving contact group 200 is movably arranged in the base 110.

[0062] The first static contact 300 includes a first connection terminal 310, a first conduction terminal 320 and a second conduction terminal 330. The first connection terminal 310 is arranged outside the base 110 and is used for electrically connecting with an external power source or load. The first conduction terminal 320 and the second conduction terminal 330 are arranged inside the base 110. The second static contact 400 includes a second connection terminal 410 and a third conduction terminal 420. The second connection terminal 410 is arranged outside the base 110 and is used for electrically connecting with an external power source or load. The third conduction terminal 420 is arranged inside the base 110. The third static contact 500 includes a third connection terminal 510 and a fourth conduction terminal 520. The third connection terminal 510 is arranged outside the base 110 and is used for electrically connecting with an external power source or load. The fourth conduction terminal 520 is arranged inside the base 110.

[0063] The output shaft of the motor 600 is connected to the moving contact group 200. The motor 600 drives the moving contact group 200 to move, so that the moving contact group 200 contacts the first conduction terminal 320 and the third conduction terminal 420 at the same time, so as to conduct the first static contact 300 and the second static contact 400 through the moving contact group 200. Or, the motor 600 drives the moving contact group 200 to move, so that the moving contact group 200 contacts the second conduction terminal 330 and the fourth conduction terminal 520 at the same time, so as to conduct the first static contact 300 and the third static contact 500 through the moving contact group 200.

[0064] An installation space is arranged in the base 110, and the moving contact group 200 is movably arranged in the installation space. A plurality of installation grooves can be arranged on the base 110, so that the first static contact 300, the second static contact 400 and the third static contact 500 are all partially arranged in the installation space.

[0065] When the first terminal 310 of the first static contact 300 is connected to an external power supply, the second terminal 410 of the second static contact 400 is electrically connected to a load. At the same time, the third terminal 510 of the third static contact 500 is also electrically connected to the load. Alternatively, when the first terminal 310 of the first static contact 300 is electrically connected to the load, the second terminal 410 of the second static contact 400 is connected to the external power supply, and at the same time, the third terminal 510 of the third static contact 500 is also connected to the external power supply. In this way, the electric switch can control the on / off of two sets of circuits simultaneously.

[0066] The first conduction end 320 and the second conduction end 330 can be part of the first static contact 300 within the installation space. The first conduction end 320 can contact the moving contact group 200, or the second conduction end 330 can contact the moving contact group 200, so that the first static contact 300 can be connected to the moving contact group 200.

[0067] The third conduction end 420 can be part of the second static contact 400 within the installation space. The third conduction end 420 can contact the moving contact group 200, so that the second static contact 400 can be connected to the moving contact group 200.

[0068] The fourth conduction end 520 can be part of the third static contact 500 within the installation space. The fourth conduction end 520 can contact the moving contact group 200, so that the third static contact 500 can be connected to the moving contact group 200.

[0069] The output shaft of the motor 600 is connected to the moving contact group 200. When the motor 600 drives the moving contact group 200 to move so that the moving contact group 200 contacts the first conduction end 320 and the third conduction end 420 simultaneously, the first set of circuits connected to the electric switch is turned on. When the motor 600 drives the moving contact group 200 to move so that the moving contact group 200 contacts the second conduction end 330 and the fourth conduction end 520 simultaneously, the second set of circuits connected to the electric switch is turned on.

[0070] In some possible cases, the rotation speed of the motor 600 is relatively fast. If the rotation speed of the motor 600 is too fast, then when the motor 600 drives the moving contact group 200 to move, the moving contact group 200 connected to the output shaft of the motor 600 may be damaged due to high-speed rotation. In view of this, a speed reduction component can be provided between the motor 600 and the moving contact group 200, and the speed reduction component is used to reduce the rotation speed of the moving contact group 200, thereby increasing the service life of the moving contact group 200.

[0071] In summary, in the present application, the movement of the moving contact group 200 is driven by the motor 600, which is more convenient compared to the traditional method of manually operating the switch. This avoids the problem of having to operate a large number of switches manually due to a large number of switches during use, saving the use of human resources during the use process.

[0072] Moreover, the present application provides a first static contact 300, a second static contact 400, and a third static contact 500. When the motor 600 drives the moving contact group 200 to move so that both the first static contact 300 and the second static contact 400 are in contact with the moving contact group 200, the first set of circuits connected to the electric switch is turned on. When the motor 600 drives the moving contact group 200 to move so that both the first static contact 300 and the third static contact 500 are in contact with the moving contact group 200, the second set of circuits connected to the electric switch is turned on. Such a setting enables the electric switch to simultaneously control the on and off of two sets of circuits through the motor 600, thereby saving the setting of one electric switch and achieving the purpose of saving the material cost during the use process.

[0073] There can be various movement modes of the moving contact group 200. For example, the moving contact group 200 can perform translation, or the moving contact group 200 can perform rotation. As long as the moving contact group 200 can be in contact with the first conduction end 320 and the third conduction end 420 simultaneously during movement, or can be in contact with the second conduction end 330 and the fourth conduction end 520 simultaneously, the embodiments of the present application do not limit the movement mode of the moving contact group 200. Hereinafter, taking the movement mode of the moving contact group 200 being rotation as an example, the specific structure and operation process of the electric switch will be described in detail.

[0074] Figure 6 It is a schematic structural diagram of the moving contact group provided by the embodiment of the present application.

[0075] As shown in Figure 3 、 Figure 4 and Figure 6 The moving contact group 200 includes a moving contact bridge 210 and a rotating shaft 220. The moving contact bridge 210 is fixedly connected to the rotating shaft 220. A first moving contact 211 is provided at the first end of the moving contact bridge 210, and a second moving contact 212 is provided at the second end of the moving contact bridge 210. Both the first conduction end 320 and the second conduction end 330 are located on the rotation path of the first moving contact 211. Both the third conduction end 420 and the fourth conduction end 520 are located on the rotation path of the second moving contact 212. The motor 600 drives the rotating shaft 220 to rotate, so that the first moving contact 211 is in contact with the first conduction end 320, and at the same time the second moving contact 212 is in contact with the third conduction end 420. Or, the motor 600 drives the rotating shaft 220 to rotate, so that the first moving contact 211 is in contact with the second conduction end 330, and at the same time the second moving contact 212 is in contact with the fourth conduction end 520.

[0076] The moving contact bridge 210 includes a first end and a second end that are opposite in position. The first moving contact 211 is disposed at the first end, and the second moving contact 212 is disposed at the second end.

[0077] The moving contact group 200 includes a rotating shaft 220. The rotating shaft 220 is provided with a slot. The moving contact bridge 210 passes through the slot provided in the rotating shaft 220 and is fixedly connected to the rotating shaft 220. When the rotating shaft 220 rotates, the moving contact bridge 210 will rotate together with the rotating shaft 220, and the first moving contact 211 and the second moving contact 212 will also rotate together with the moving contact bridge 210. Both the first conduction end 320 and the second conduction end 330 are located on the rotation path of the first moving contact 211. When the first moving contact 211 rotates with the moving contact bridge 210, the first moving contact 211 can contact the first conduction end 320 or the second conduction end 330. When the second moving contact 212 rotates with the moving contact bridge 210, the second moving contact 212 can contact the third conduction end 420 or the fourth conduction end 520.

[0078] In summary, in the present application, the moving contact group 200 is arranged to be rotatably connected to the base 110. The rotation of the rotating shaft 220 can be used to drive the moving contact bridge 210 to rotate, so that when the first moving contact 211 contacts the first conduction end 320, the second moving contact 212 contacts the third conduction end 420, or when the first moving contact 211 contacts the second conduction end 330, the second moving contact 212 contacts the fourth conduction end 520. The rotation of the motor 600 is used to drive the rotating shaft 220 to rotate, thereby driving the moving contact bridge 210 to rotate. In this way, the purpose of simultaneously controlling the conduction or disconnection of two circuits by an electric switch can be achieved.

[0079] In the present application, the forward and reverse rotation of the motor can be controlled by the first microswitch 121 and the second microswitch 122, so as to realize the control of the moving contact group 200 by the motor 600.

[0080] Exemplarily, Figure 7 is a partial internal structure schematic diagram of the electric switch provided by an embodiment of the present application, as Figure 2 and Figure 7 shown. The electric switch includes a first microswitch 121 and a second microswitch 122. Both the first microswitch 121 and the second microswitch 122 are electrically connected to the motor 600. The first microswitch 121 is used to control the motor 600 so that the first moving contact 211 contacts the first conduction end 320, and at the same time, the second moving contact 212 contacts the third conduction end 420. The second microswitch 122 is used to control the motor 600 so that the first moving contact 211 contacts the second conduction end 330, and at the same time, the second moving contact 212 contacts the fourth conduction end 520.

[0081] The first microswitch 121 and the second microswitch 122 can be connected in series with the motor 600.

[0082] The first microswitch 121 can control the motor 600 to rotate forward, reverse or stop, so as to control the moving contact group 200 to rotate forward, reverse or stop. The second microswitch 122 can also control the motor 600 to rotate forward, reverse or stop, so as to control the moving contact group 200 to rotate forward, reverse or stop.

[0083] Among them, when the first microswitch 121 controls the motor 600 to rotate forward, the second microswitch 122 is in the off state. When the second microswitch 122 controls the motor 600 to rotate in reverse, the first microswitch 121 is in the off state.

[0084] Through the above settings, the present application can use the first microswitch 121 and the second microswitch 122 to control the rotation of the motor 600, so as to control the movement of the moving contact group 200. Compared with manually controlling the opening and closing of the motor 600 on site, both the first microswitch 121 and the second microswitch 122 can be connected to a signal receiver, and with the cooperation of a signal generator, remote control of the electric switch for line switching or on / off can be realized. In this way, the operation of the electric switch can be made more convenient.

[0085] Figure 8 It is a schematic structural diagram of the driving component provided by the embodiment of the present application. Figure 9 is Figure 7 an enlarged view of part A in

[0086] In actual use, when controlling the forward and reverse rotation of the motor 600 through the first microswitch 121 or the second microswitch 122, it is possible that the first microswitch 121 or the second microswitch 122 accidentally touches the start button of the motor 600, causing the motor 600 to drive the moving contact group 200 to move, resulting in the problem that the moving contact group 200 is displaced. In this way, the circuit may be disconnected or the moving contact group 200 may be damaged. In order to reduce the possibility of these problems occurring, the present application has made the following improvements.

[0087] Such as Figures 7 to 9As shown, the housing 100 further includes a middle cover 120, and the middle cover 120 is covered on the base 110. A driving assembly 700 is provided on the side of the middle cover 120 facing away from the base 110. The output shaft of the motor 600 is connected to the driving assembly 700. A driving part is provided on the side of the driving assembly 700 facing the middle cover 120, and a driven part is provided on the rotating shaft 220. The driving part passes through the middle cover 120 and is connected to the driven part. The driving assembly 700 is provided with a first protrusion 711 and a first groove 712. When the first microswitch 121 controls the rotation of the motor 600, the start button of the first microswitch 121 is located in the first groove 712, and at the same time, the start button of the second microswitch 122 abuts against the first protrusion 711. Alternatively, when the second microswitch 122 controls the rotation of the motor 600, the start button of the first microswitch 121 abuts against the first protrusion 711, and at the same time, the start button of the second microswitch 122 is located in the first groove 712.

[0088] After the middle cover 120 and the base 110 are covered, an installation space is formed, and the moving contact group 200 is located in this installation space. Since the size of this installation space is limited, the driving assembly 700 can be arranged on the side of the middle cover 120 facing away from the base 110.

[0089] The driving assembly 700 can rotate together with the output shaft of the motor 600. The driving part can be a plug structure provided on the side of the driving assembly 700 facing the middle cover 120, and the driving part can also be a slot structure provided on the side of the driving assembly 700 facing the middle cover 120. Correspondingly, the driven part can be a slot structure provided on the side of the rotating shaft 220 facing the middle cover 120, and the driven part can also be a plug structure provided on the side of the rotating shaft 220 facing the middle cover 120.

[0090] When the driving assembly 700 is arranged on the side of the middle cover 120 facing away from the base 110, through holes can be provided on the middle cover 120. In this way, the driving part can pass through the through holes and extend into the aforementioned installation space, and cooperate with the driven part located in the installation space to achieve the purpose of driving the rotating shaft 220 to rotate by the driving assembly 700.

[0091] The driving assembly 700 is arranged between the first microswitch 121 and the second microswitch 122, and the first microswitch 121 and the second microswitch 122 can be symmetrically arranged with the driving assembly 700 as the axis of symmetry.

[0092] The first microswitch 121 is provided with a start button. When the start button of the first microswitch 121 is pressed, the first microswitch 121 can control the motor 600 to rotate forward. When the start button of the first microswitch 121 pops up, the first microswitch 121 cannot control the motor 600 to rotate forward.

[0093] Similarly, the second microswitch 122 is also provided with a start button. When the start button of the second microswitch 122 is pressed, the second microswitch 122 can control the motor 600 to reverse. When the start button of the second microswitch 122 pops up, the second microswitch 122 cannot control the motor 600 to continue reversing.

[0094] When controlling the start buttons of the first microswitch 121 and the second microswitch 122 to pop up or be pressed, the driving component 700 can be provided with a first protrusion 711 and a first groove 712.

[0095] When the first microswitch 121 controls the motor 600 to rotate, the start button of the first microswitch 121 abuts against the first protrusion 711. The motor 600 drives the driving component 700 to rotate, and the first protrusion 711 and the first groove 712 rotate together with the driving component 700 until the start button of the first microswitch 121 is located in the first groove 712. At this time, the first microswitch 121 cannot control the motor 600 to rotate, and the moving contact group 200 stops moving.

[0096] When the first microswitch 121 cannot control the motor 600 to rotate, the start button of the second microswitch 122 abuts against the first protrusion 711. At this time, the second microswitch 122 can control the motor 600 to rotate until the start button of the second microswitch 122 is located in the first groove 712. At this time, the second microswitch 122 cannot control the motor 600 to rotate, and the moving contact group 200 stops moving.

[0097] Among them, the first protrusion 711 can be integrally formed with the driving component 700, or the first protrusion 711 can be formed separately from the driving component 700 and then assembled. The first groove 712 can be provided on the driving component 700 by means of engraving or cutting, or the part of the driving component 700 without the first protrusion 711 can be configured as the first groove 712.

[0098] Through the above settings, when the start button of the first microswitch 121 is located in the first groove 712, the motor 600 cannot be controlled by the first microswitch 121. When the start button of the second microswitch 122 is located in the first groove 712, the motor 600 cannot be controlled by the second microswitch 122. In this way, the rotation of the motor 600 can be restricted. It avoids the problem that due to accidental touching of the start button of the motor 600, the motor 600 drives the moving contact group 200 to move, resulting in the position deviation of the moving contact group 200, the disconnection of the circuit or the damage of the moving contact group 200, increases the reliability of the use of the electric switch, and also increases the service life of the moving contact group 200.

[0099] Based on the description of the previous embodiment, in some possible designs, such as Figures 7 to 9 The driving assembly 700 may include a first gear 710 , and a first protrusion 711 and a first groove 712 are both disposed on the first gear 710 .

[0100] The first gear 710 may be a full-tooth structure, and a columnar structure is provided on the side of the first gear 710 facing away from the middle cover 120, and the columnar structure may be cylindrical or prismatic, etc. The first protrusion 711 and the first groove 712 may both be provided on the side wall of the columnar structure, and the first protrusion 711 and the first groove 712 may be provided at different positions of the columnar structure.

[0101] To sum up, because the first gear 710 has the advantages of constant transmission ratio, wide application range and easy maintenance, the drive component 700 is configured as the first gear 710, which is relatively simple both in the early installation process and in the later maintenance, and the rotation of the first gear 710 is relatively stable, which can increase the reliability of the use of the electric switch.

[0102] Based on the description of the previous embodiments, the electric switch of the present application can control the on and off of two circuits. In actual use, in order to facilitate the user to have a clear understanding of the on and off of a certain circuit, the present application also makes the following improvements.

[0103] For example, Figure 10 for Figure 7 A magnified view of part B in the figure. Figure 11 for Figure 7 The enlarged view of part C in the figure is as follows: Figure 7 , Figure 10 as well as Figure 11 As shown, the electric switch may further include a third micro switch 123 and a first indicator light, the third micro switch 123 is electrically connected to the first indicator light, and the drive assembly 700 is further provided with a second protrusion 721 and a second groove 722. When the first stationary contact 300 and the second stationary contact 400 are conducting, the start button of the third micro switch 123 abuts against the second protrusion 721, and the third micro switch 123 controls the first indicator light to light up. When the start button of the third micro switch 123 is located in the second groove 722, the third micro switch 123 controls the first indicator light to turn off.

[0104] And / or, the electric switch further includes a fourth micro switch 124 and a second indicator light. The fourth micro switch 124 is connected to the second indicator light. The driving assembly 700 further has a third protrusion 731 and a third groove 732. When the first stationary contact 300 is electrically connected to the third stationary contact 500, the start button of the fourth micro switch 124 abuts against the third protrusion 731, and the fourth micro switch 124 controls the second indicator light to turn on. When the start button of the fourth micro switch 124 is located within the third groove 732, the fourth micro switch 124 controls the second indicator light to turn off.

[0105] When the first stationary contact 300 is electrically connected to the second stationary contact 400, the start button of the first micro switch 121 is located within the first groove 712, and the start button of the third micro switch 123 abuts against the second protrusion 721. At this time, the first micro switch 121 cannot control the motor 600 to rotate, the first stationary contact 300 and the second stationary contact 400 will not disconnect, and the third micro switch 123 can control the first indicator light to turn on.

[0106] When the first stationary contact 300 is electrically connected to the third stationary contact 500, the start button of the second micro switch 122 is located within the first groove 712, and the start button of the fourth micro switch 124 abuts against the third protrusion 731. At this time, the second micro switch 122 cannot control the motor 600 to rotate, the first stationary contact 300 and the third stationary contact 500 will not disconnect, and the fourth micro switch 124 can control the second indicator light to turn on.

[0107] During the process of switching from the conduction between the first stationary contact 300 and the second stationary contact 400 to the conduction between the first stationary contact 300 and the third stationary contact 500, the start button of the third micro switch 123 moves from the position abutting against the second protrusion 721 to within the second groove 722. At the same time, the start button of the fourth micro switch 124 moves out of the third groove 732 to abut against the third protrusion 731.

[0108] The third micro switch 123 and the fourth micro switch 124 can have multiple functions. When the third micro switch 123 and the fourth micro switch 124 are not connected to the indicator lights, the third micro switch 123 and the fourth micro switch 124 can also provide two passive dry contacts for the user, so that the user can select corresponding devices to be connected to the third micro switch 123 and the fourth micro switch 124 according to actual needs. For example, the third micro switch 123 and the fourth micro switch 124 can also be electrically connected to some small control electrical appliances.

[0109] With the above settings, the present application provides a third microswitch 123 and a fourth microswitch 124 inside the electric switch, and connects the third microswitch 123 to the first indicator light and the fourth microswitch 124 to the second indicator light. During the process of the driving assembly 700 rotating to drive the moving contact group 200 to rotate, the second protrusion 721, the second groove 722 and the start button of the third microswitch 123 can be cooperated, and the third protrusion 731, the third groove 732 and the start button of the fourth microswitch 124 can be cooperated to control the lighting or extinguishing of the first indicator light and the second indicator light.

[0110] Moreover, the first protrusion 711 and the second groove 722 on the driving assembly 700 also cooperate with the first microswitch 121 and the second microswitch 122. In this way, when the driving assembly 700 rotates to drive the first static contact 300 to conduct with the second static contact 400, the first indicator light can be lit to indicate that one of the circuits has been conducted. When the driving assembly 700 rotates to drive the first static contact 300 to conduct with the third static contact 500, the second indicator light can be lit to indicate that the other circuit has been conducted. This enables the user to clearly recognize the conduction and disconnection of a certain circuit without spending more time making judgments, saving the labor cost during use.

[0111] As Figure 8 shown, in some embodiments, the driving assembly 700 further includes a second gear 720 and a third gear 730. The second protrusion 721 and the second groove 722 are both provided on the second gear 720, and the third protrusion 731 and the third groove 732 are both provided on the third gear 730.

[0112] The first gear 710 can be disposed between the second gear 720 and the third gear 730 and meshes with the second gear 720 and the third gear 730. The output shaft of the motor 600 can be connected to any one of them, and the first gear 710, the second gear 720 and the third gear 730 can be rotated.

[0113] With the above settings, the second protrusion 721 and the second groove 722 are provided on the second gear 720, and the third protrusion 731 and the third groove 732 are provided on the third gear 730, so that the first gear 710, the second gear 720 and the third gear 730 are meshed with each other. In this way, without affecting the cooperation between the second protrusion 721 and the second groove 722 and the third microswitch 123, and the cooperation between the third protrusion 731 and the third groove 732 and the fourth microswitch 124, the functions of the first gear 710 are dispersed. It is no longer necessary to provide all of the first protrusion 711, the first groove 712, the second protrusion 721, the second groove 722, the third protrusion 731 and the third groove 732 on the first gear 710, which increases the fault tolerance rate of the first gear 710 during use, thereby increasing the fault tolerance rate during the use of the electric switch and improving the reliability of the electric switch during use.

[0114] Figure 12 FIG. is a schematic structural diagram of the base provided by the embodiment of the present application. Figure 13 FIG. is a schematic partial internal structural diagram of the electric switch provided by the embodiment of the present application.

[0115] As Figure 12 and Figure 13 shown, the base 110 is provided with a first limiting structure 111, the first limiting structure 111 is located on the rotation path of the first end, and the first limiting structure 111 is used to limit the position of the first end. And / or, the base 110 is provided with a second limiting structure 112, the first limiting structure 111 is located on the rotation path of the second end, and the second limiting structure 112 is used to limit the position of the second end.

[0116] The first limiting structure 111 can be two, and the two first limiting structures 111 are symmetrically arranged. The first limiting structure 111 can be a protrusion provided on the inner wall of the base 110, or the first limiting structure 111 can be a groove provided on the inner wall of the base 110, or the first limiting structure 111 can be the inner wall of the base 110. When the first moving contact 211 contacts the first conducting end 320 or the second conducting end 330, the first limiting structure 111 limits the movement of the first end.

[0117] The second limiting structure 112 can also be two, and the two second limiting structures 112 are symmetrically arranged. The second limiting structure 112 can be a protrusion provided on the inner wall of the base 110, or the second limiting structure 112 can be a groove provided on the inner wall of the base 110, or the second limiting structure 112 can be the inner wall of the base 110. When the second moving contact 212 contacts the third conducting end 420 or the fourth conducting end 520, the second limiting structure 112 limits the movement of the second end.

[0118] With the above settings, the first limiting structure 111 and the second limiting structure 112 are arranged in the base 110, which can limit the movement of the first end and the second end. When the first moving contact 211 contacts the first conducting end 320 or the second conducting end 330, the arrangement of the first limiting structure 111 can reduce the probability of the problem that the first moving contact 211 breaks contact with the first conducting end 320 or the second conducting end 330 due to excessive movement of the first end. When the second moving contact 212 contacts the third conducting end 420 or the fourth conducting end 520, the arrangement of the second limiting structure 112 can reduce the probability of the problem that the second moving contact 212 breaks contact with the third conducting end 420 or the fourth conducting end 520 due to excessive movement of the second end. In this way, the reliability of the electric switch in use can be increased.

[0119] Figure 14 The structural schematic diagram of the middle cover provided by the embodiment of the present application.

[0120] As Figure 6 and Figure 14 shown, a third limiting structure 125 is provided on the side of the middle cover 120 facing the base 110, and a matching structure 230 adapted to the third limiting structure 125 is provided on the rotating shaft 220. The middle cover 120 is covered on the base 110, and the third limiting structure 125 is matched with the matching structure 230 to limit the rotation of the rotating shaft 220.

[0121] The third limiting structure 125 can be a long strip-shaped convex structure provided on the side of the middle cover 120 facing the base 110, and the third limiting structure 125 can be a long strip-shaped groove structure provided on the side of the middle cover 120 facing the base 110. Correspondingly, the matching structure 230 can be a long strip-shaped groove structure provided on the rotating shaft 220 facing the middle cover 120, or the matching structure 230 can be a long strip-shaped convex structure provided on the rotating shaft 220 facing the middle cover 120. The length of the convex structure is less than the length of the groove structure.

[0122] When the middle cover 120 is covered with the base 110, the convex structure is located in the groove structure. When the rotating shaft 220 rotates, the groove walls at both ends of the long strip-shaped groove structure play a limiting role on the convex structure, reducing the probability of the problem that the first moving contact 211 breaks contact with the first conducting end 320 or the second conducting end 330 due to excessive rotation of the rotating shaft 220, and at the same time reducing the probability of the problem that the second moving contact 212 breaks contact with the third conducting end 420 or the fourth conducting end 520.

[0123] In summary, a third limiting structure 125 is provided on one side of the middle cover 120 facing the base 110, and a mating structure 230 is provided on one side of the rotating shaft 220 facing the middle cover 120. The rotation of the rotating shaft 220 can be limited by the cooperation of the third limiting structure 125 and the mating structure 230, improving the reliability of the electric switch during use.

[0124] As Figure 1 and Figure 2 shown, the electric switch further includes an upper cover 130. The upper cover 130 is provided with a handle operation hole 131, and the position of the handle operation hole 131 corresponds to that of the driving assembly 700. The handle operation hole 131 is used for an external handle to pass through to operate the driving assembly 700.

[0125] The handle operation hole 131 can be a through hole provided on the upper cover 130, and the position of the handle operation hole 131 corresponds to that of the driving assembly 700.

[0126] With the above arrangement, when the motor 600 fails and cannot control the movement of the moving contact group 200, the operating assembly can still be controlled by passing a handle through the handle operation hole 131 to enable the movement of the moving contact group 200. In this way, the use of the electric switch can be guaranteed, improving the reliability of the electric switch during use.
