To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 1 shows a schematic diagram of a first viewing angle of a switch 001 according to an embodiment of the present application. Fig. 2 is a schematic diagram illustrating a first view angle of the switch 001 according to an embodiment of the present application, where a portion of the housing 030 is removed from the switch 001.

As shown in fig. 1 and 2, the diverter switch 001 includes a switch assembly 010 and a housing 030. The switch assembly 010 includes a first elastic member 300, a first movable portion 100, and a first fixed portion 200. The first fixed portion 200 is fixedly connected to the casing 030, and the first movable portion 100 is slidably engaged with the casing 030 along the first direction X.

Fig. 3 is a schematic diagram illustrating a first view angle of a switch 001 according to an embodiment of the present application, wherein the switch 001 is provided with a casing 030 removed. Fig. 4 shows a cross-sectional view in the direction IV-IV in fig. 2.

Referring to fig. 3 and 4, the first movable portion 100 includes a first movable contact 110, and the first fixed portion 200 includes a first fixed contact 210. The first movable portion 100 and the first fixed portion 200 are disposed at an interval in the first direction X, the two first elastic members 300 act on the first movable portion 100, and the elastic force of the first elastic members 300 can drive the first movable portion 100 to have a tendency of being parallel to the first direction X and being away from the first fixed portion 200, that is, drive the first movable contact 110 to be away from the first fixed contact 210. When an external force is applied to the first movable part 100, the elastic force of the first elastic member 300 can be overcome, so that the first movable part 100 approaches the first fixed part 200, and the first movable contact 110 contacts the first fixed contact 210, thereby achieving the electrical connection between the first movable contact 110 and the first fixed contact 210.

The switch assembly 010 further includes a linkage 400. The linkage portion 400 includes a pressing piece 430, and the pressing piece 430 is capable of being engaged with the first movable portion 100. When the linkage portion 400 moves, the pressing block 430 can contact the first movable portion 100 to apply an external force to the first movable portion 100, so that the first movable portion 100 presses the second movable portion 500, and the first movable contact 110 contacts the first fixed contact 210.

The switch 001 further comprises a driver 900. The number of the switch assemblies 010 in the switch 001 is eight, and the eight switch assemblies 010 are arranged in parallel in the second direction Y. The linkage 400 includes gears 410, and the gears 410 of the adjacent two switch assemblies 010 mesh. The output end of the driving member 900 is fixedly connected to the gear 410 of a switch assembly 010 located in the middle, and the driving member 900 can use a stepping motor to accurately drive the gear 410 to rotate. For convenience of description, the gear 410 directly connected to the driving member 900 is named a driving gear 410, and the remaining 7 gears 410 are named driven gears 410. When the driving gear 900 drives the driving gear 410 to rotate, the driving gear 410 drives the adjacent driven gears 410 to rotate synchronously, and the driven gear 410 directly connected to the driving gear 410 drives the other driven gears 410 to rotate synchronously. The switch assemblies 010 are in linkage fit through the gears 410, and one driving member 900 can drive all the switch assemblies 010 to move synchronously.

The pressing block 430 is fixedly connected with the gear 410. The pressing piece 430 extends radially from the axial center of the gear 410. As the gear 410 rotates, one end of the pressing piece 430, which is away from the axial center of the gear 410, can act on the first movable portion 100, pressing the first movable portion 100 toward the second movable portion 500.

The pressing block 430 includes a first portion 431, a second portion 433, and a second elastic member 435. The first part 431 is fixedly connected with the gear 410, and the first part 431 is provided with a sliding groove 4311. The second portion 433 extends into the slot 4311 and is slidably engaged with the first portion 431 through the slot 4311. The second elastic member 435 has one end acting on the first part 431 and the other end acting on the second part 433. The second elastic member 435 is a compression spring, and provides the second part 433 with an elastic force away from the first part 431. When the gear 410 rotates to press the pressing block 430 to the first movable portion 100, the second portion 433 acts on the first movable portion 100 elastically, so that on one hand, a rigid force between the pressing block 430 and the first movable portion 100 can be reduced, and on the other hand, the first movable contact 110 acts on the first fixed contact 210 elastically through an elastic force of the second elastic member 435, so that the first movable contact 110 and the first fixed contact 210 can be in stable contact, and a relatively small pressure is kept between the first movable contact 110 and the first fixed contact 210.

The first movable part 100 includes a first mounting block 230 and a boss 250, and the first movable contact 110 is fixedly disposed on a surface of the first mounting block 230 facing the first fixed contact 210. The boss 250 is located on a surface of the first mounting block 230 away from the first fixed contact 210, and the boss 250 is fixedly connected to the first mounting block 230. The cross section of the boss 250 perpendicular to the third direction Z is trapezoidal, that is, two sides of the boss 250 along the first direction X are respectively provided with an inclined side surface 251, and a surface of the boss 250 away from the first fixed contact 210 is a top surface 253. When the gear 410 rotates, the gear 410 drives the pressing block 430 to contact one of the inclined side surfaces 251, and the pressing block 430 slides on the inclined side surface 251 and gradually presses the first movable portion 100 downward, so that the first movable portion 100 approaches the first fixing portion 200. Until the pressing piece 430 is separated from the inclined side surface 251, the pressing piece 430 is in contact with the top surface 253, at which time the first movable contact is in contact with the first stationary contact, and the first movable contact is maintained in contact with the first stationary contact as the gear 410 is further rotated until the second elastic member 435 is parallel to the first direction X, but the second elastic member 435 is gradually compressed.

An arc-shaped groove 255 is further formed on the top surface 253 of the boss 250, when the gear 410 rotates until the second elastic member 435 is parallel to the first direction X, the end of the boss 250 extends into the arc-shaped groove 255, and the second elastic member 435 is properly extended, but the first movable contact can still be brought into contact with the first stationary contact.

The end of the second portion 433 is configured as a spherical head, which can slide along the surface of the boss 250 more smoothly when contacting the boss 250.

It will be appreciated that the boss 250 may also be in the shape of a truncated pyramid or other shapes.

It is understood that each switch assembly 010 of the switch 001 can also rotate by using other transmission forms such as a chain wheel.

It can be understood that the boss 250 can also be set as a reciprocating sleeve, the gear 410 is set as a duplicate gear 410, the part with the large reference circle diameter is used for meshing transmission of each switch component 010, the part with the small reference circle diameter is only provided with gear teeth on the minor arc part, the reciprocating sleeve is provided with a long hole extending along the first direction X, racks are arranged on two sides of the long hole, the part with the small reference circle diameter is inserted into the long hole, along with the rotation of the duplicate gear 410, the part with the small reference circle diameter moves upwards along the first direction X when meshed with the rack on one side, and moves downwards along the first direction X when meshed with the rack on the other side, so that the reciprocating movement of the reciprocating sleeve is realized.

The linkage portion 400 of the switch assembly 010 has eight states, and the states here refer to the rotation angles of the gears 410 in the linkage portion 400. When the linkage portion 400 is in one of the states, the pressing block 430 can press the first movable portion 100 toward the second movable portion 500, and the first movable contact 110 is in contact with the first fixed contact 210, so that the first movable contact 110 is electrically connected to the first fixed contact 210. At the same point in time. The linkage portions 400 of the eight switch assemblies 010 of the change-over switch 001 are in different states, that is, only the first movable portion 100 of one switch assembly 010 is pressed toward the second movable portion 500 by the pressing block 430 at the same time, and the first movable contacts 110 and the first fixed contacts 210 of the other seven switch assemblies 010 do not contact. As the driving member 900 drives the gear 410 to rotate, the first movable contact 110 and the first fixed contact 210 of different switch assemblies 010 can be brought into contact.

Referring back to fig. 1 and 2, the switch assembly 010 further includes a second movable portion 500, a second fixed portion 600, and a third elastic member 700. The second fixed portion 600 is fixedly connected to the casing 030, and the second movable portion 500 is slidably engaged with the casing 030 along the first direction X.

Referring to fig. 3 and 4, the second movable portion 500 includes a second movable contact 510, and the second fixed portion 600 includes a second fixed contact 610. The second movable portion 500 and the second fixed portion 600 are disposed at an interval in the second direction Y. The third elastic member 700 has one end acting on the casing 030 to achieve connection with the second fixing portion 600 and the other end acting on the second movable portion 500, and the third elastic member 700 provides an elastic force for the second movable portion 500 to move away from the second fixing portion 600. The first elastic member 300 has one end applied to the first movable portion 100 and the other end applied to the second movable portion 500. The first elastic member 300 acts on the first movable portion 100 to make the first movable portion 100 have a tendency to be away from the first fixed portion 200, and transmits the movement of the first movable portion 100 in the first direction X to the second movable portion 500 to make the second movable portion 500 be pressed down synchronously when the first movable portion 100 is pressed down by the interlocking portion 400.

When the first movable portion 100 is pressed down by the linkage portion 400, the first elastic member 300 provides an elastic pressing force for the second movable portion 500, so that the second movable portion 500 overcomes the elastic force of the third elastic member 700 to approach the second fixed portion 600, and the second movable contact 510 contacts the second fixed contact 610, thereby achieving the electrical connection between the second movable contact 510 and the second fixed contact 610.

The first fixed contact 210 is connected to a first electrical connector of an electrical device, and the second fixed contact 610 is connected to a second electrical connector of the electrical device. The first movable contact 110 is connected to the live wire of the power grid and the second movable contact is connected to the neutral wire of the power grid. When the first moving contact 110 contacts with the first fixed contact 210 and the second moving contact 510 contacts with the second fixed contact 610, the live wire of the power grid is electrically connected with the first electrical connector of the electrical equipment, and the zero wire of the power grid is electrically connected with the second electrical connector of the electrical equipment, so that the power supply of the power grid to the electrical equipment is realized.

It can be understood that, under the condition that the second movable portion 500 and the second fixed portion 600 are not provided, the second electrical connector of the electrical equipment can be always connected to the zero line of the power grid, and whether the first electrical connector is electrically connected to the live wire or not is controlled by independently controlling whether the first movable contact 110 and the first fixed contact 210 are released or not, so as to control the on/off of the electrical equipment.

It can be understood that the first movable contact 110 and the second movable contact 510 may also be connected to a power supply device such as a battery, and the battery provides power for the electric device.

Optionally, the first movable contact 110 may also be connected to a first electrical connector of an electrical device, and the first fixed contact 210 is connected to a live line of an electrical grid. The second moving contact 510 may also be connected to a second electrical connector of the electrical device, and the second fixed contact 610 is connected to a neutral line of an electrical grid.

The linkage portions 400 of the eight switch assemblies 010 of the switch 001 are in different states, so that only one of the eight electric devices connected to the switch 001 can be turned on at a time, and the other seven electric devices are in off states.

The first switch assembly 010 is in a state where the first movable contact 110 is in contact with the first fixed contact 210, and the other 7 switch assemblies 010 are in a state where the first movable contact 110 is separated from the first fixed contact 210. The driving member 900 is engaged with the gear 410 of the fourth switch assembly 010, so that the driving member 900 can drive the gears 410 of all the switch assemblies 010 to rotate. Due to the meshed characteristics of the gears 410, the rotation directions of the gears 410 of the first, third, fifth and seventh switch assemblies 010, 010 are the same, and the rotation directions of the gears 410 of the second, fourth, sixth and eighth switch assemblies 010, 010 are the same.

At the time shown in fig. 5, the pressing blocks 430 of the switch assemblies 010 are in the following correspondence: the pressing piece 430 of the first switch assembly 010 is parallel to the first direction X, the pressing piece 430 of the second switch assembly 010 rotates clockwise by 40 ° with respect to the pressing piece 430 of the first switch assembly 010, the pressing piece 430 of the third switch assembly 010 rotates counterclockwise by 80 ° with respect to the pressing piece 430 of the first switch assembly 010, the pressing piece 430 of the fourth switch assembly 010 rotates clockwise by 120 ° with respect to the pressing piece 430 of the first switch assembly 010, the pressing piece 430 of the fifth switch assembly 010 rotates counterclockwise by 160 ° with respect to the pressing piece 430 of the first switch assembly 010, the pressing piece 430 of the sixth switch assembly 010 rotates clockwise by 200 ° with respect to the pressing piece 430 of the first switch assembly 010, the pressing piece 430 of the seventh switch assembly 010 rotates counterclockwise by 240 ° with respect to the pressing piece 430 of the first switch assembly 010, and the pressing piece 430 of the eighth switch assembly 010 rotates clockwise by 280 ° with respect to the pressing piece 430 of the first switch assembly 010. Besides the eight switch assemblies 010 are in a state where the first movable contacts 110 are in contact with the first fixed contacts 210, the state where the first movable contacts 110 of all the switch assemblies 010 are not in contact with the first fixed contacts 210 is also provided, that is, when the first switch assembly 010 rotates counterclockwise by 320 °, the first movable contacts 110 of all the switch assemblies 010 are not in contact with the first fixed contacts 210. At this time, all the electric devices corresponding to the switch assemblies 010 are in the off state.

The movement of the linkage part 400 is controlled by the change-over switch 001, so that the electric equipment needing to be started is in a starting state, and other electric equipment needing to be stopped is turned off. Optionally, the switch 001 may be connected to only one electric device, and the electric device has eight power modules, the eight power modules correspond to the eight switch assemblies 010 respectively, and the first movable portion 100 and the first fixing portion 200 of the switch assemblies 010 are selected to be different from each other, and the second movable portion 500 and the second fixing portion 600 are selected to be different from each other, so that the electric device can operate under corresponding power.

It is understood that the number of switch assemblies 010 in the switch 001 may also be 2, 3 or other numbers greater than 2. The linkage portions 400 of the switch assemblies 010 are in linkage fit, so that when the linkage portion 400 of one switch assembly 010 moves, the linkage portions 400 of other switch assemblies 010 move synchronously. Therefore, at the same time, only the first movable contact 110 and the first fixed contact 210 of one switch assembly 010 in all the switch assemblies 010 are in contact, and the first movable contacts 110 and the first fixed contacts 210 of the other switch assemblies 010 are not in contact.

The second fixed contact 610 includes a second power supply fixed contact 611 and a second power use fixed contact 613, and the second movable contact 510 includes a second power supply movable contact 511 and a second power use movable contact 513.

It can be understood that, when the first moving contact 110 is a single moving contact and the first fixed contact 210 is a single fixed contact, the live wire of the power grid can be electrically connected to the first moving contact 110 all the time through the flexible wire, and the power grid supplies power to the electric device through the contact between the first moving contact 110 and the first fixed contact 210.

It can be understood that, when the second movable contact 510 is a single movable contact and the second fixed contact 610 is a single fixed contact, the zero line of the power grid can be electrically connected to the second movable contact 510 all the time through the flexible line, and the power grid supplies power to the electric device through the contact between the second movable contact 510 and the second fixed contact 610.

When the change-over switch 001 is used, the linkage part 400 of all the switch assemblies 010 can be driven to move synchronously by the driving of one driving piece 900, so that different switch assemblies 010 are controlled to be switched, and the automation and the integration degree of the change-over switch 001 are improved. Each switch assembly 010 is driven by one driving member 900 to move according to a preset mode, so that the probability of false switching can be reduced. The linkage part 400 between the switch components 010 is in a form of meshing of the gears 410 to realize linkage, and the whole volume of the selector switch 001 is further reduced.
