[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0026] Figure 1The embodiment of the double-station linkage switch of the present invention is shown, and the double-station linkage switch includes a rotary drive member 10, a first logic gear group 20, a second logic gear group 30, a first cam mechanism 40 and a second cam mechanism 50. Among them, the output of the rotary drive member 10 is provided with a driving gear 11, the first logic gear group 20 and the second logic gear group 30 are respectively meshed with the driving gear 11, and the first cam mechanism 40 and the second cam mechanism 50 are respectively driven and connected with the first logic gear group 20 and the second logic gear group 30. The first cam mechanism 40 includes a first extended state and a first retracted state, and the second cam mechanism 50 includes a second extended state and a second retracted state. The double-station linkage switch includes a first station and a second station. In the first station, the rotating driving member 10 drives the first cam mechanism 40 to a first extended state through the first logic gear group 20, and drives the second cam mechanism 50 to a second retracted state through the second logic gear group 30; in the second station, the rotating driving member 10 drives the first cam mechanism 40 to a first retracted state through the first logic gear group 20, and drives the second cam mechanism 50 to a second extended state through the second logic gear group 30.

[0027] By applying the technical solution of the present invention, the first logic gear set 20 and the second logic gear set 30 can be driven to rotate simultaneously through a rotating driving member 10. The first logic gear set 20 and the second logic gear set 30 have different driving logics, so as to realize the linkage control of the first cam mechanism 40 and the second cam mechanism 50 at the first station and the second station. When the first cam mechanism 40 is driven to the first extended state, the second cam mechanism 50 is driven to the second retracted state; when the first cam mechanism 40 is driven to the first retracted state, the second cam mechanism 50 is driven to the second extended state. In this way, the manufacturing cost of the double-station linkage switch can be reduced.

[0028] like Figure 2 and Figure 3 As shown, optionally, in the technical solution of this embodiment, the first logic gear set 20 includes a first logic tooth 21 and a first intermittent tooth 22, the first logic tooth 21 is formed with a first gear segment 211 and a first smooth segment 212, and the first intermittent tooth 22 is formed with a first meshing tooth structure 221 that matches the first gear segment 211. The first intermittent tooth 22 is drivingly connected to the first cam mechanism 40, and the first intermittent tooth 22 is driven to rotate when the first gear segment 211 moves to the first intermittent tooth 22, and the first intermittent tooth 22 stops rotating when the first smooth segment 212 moves to the first logic tooth 21. Through the above-mentioned intermittent matching structure, the intermittent movement of the first cam mechanism 40 can be realized, so that the first cam mechanism 40 can be maintained in a certain posture.

[0029] As a preferred implementation, in the technical solution of this embodiment, Figure 3As shown, a first intermittent boss 213 is also formed on the first logical tooth 21, and the first intermittent boss 213 is arranged on the first smooth section 212. A first boundary tooth structure 222 that cooperates with the first intermittent boss 213 is formed on the first intermittent tooth 22. When the first smooth section 212 moves to the first logical tooth 21, the first intermittent boss 213 cooperates with the first boundary tooth structure 222 to prevent the first intermittent tooth 22 from rotating. The cooperation between the first intermittent boss 213 and the first boundary tooth structure 222 is equivalent to jamming the first intermittent tooth 22, so that when the rotating drive member 10 is stopped, the first cam mechanism 40 can continue to remain in a certain posture, so that the actuator connected to the first cam mechanism 40 can remain in a working position. As shown Figure 4 As shown, in the technical solution of this embodiment, more preferably, in the technical solution of this embodiment, there are at least two first boundary tooth structures 222, the two first boundary tooth structures 222 are arranged at intervals, the first intermittent boss 213 passes through the toothless space between the two first boundary tooth structures 222, and the two first boundary tooth structures 222 abut against the outer edge of the first intermittent boss 213. By arranging the two first boundary tooth structures 222 at intervals, they can just abut against the outer edge of the first intermittent boss 213, and the first intermittent tooth 22 is clamped in two rotation directions.

[0030] like Figure 3 As shown, as an optional embodiment, the first meshing tooth structure 221 and the first intermittent boss 213 are staggered in the height direction. More preferably, the first boundary tooth structure 222 is an extension of a portion of the teeth of the first meshing tooth structure 221, which can facilitate the connection of meshing and gap action. As other optional embodiments, the above mechanism can also be disassembled and designed in other ways.

[0031] like Figure 2 As shown, in the technical solution of this embodiment, the first logic gear set 20 also includes a transmission gear 23, and the transmission gear 23 is installed between the driving gear 11 and the first logic tooth 21. The output speed of the driving gear 11 can be adjusted by the transmission gear 23, thereby changing the final output torque of the first intermittent tooth 22.

[0032] It should be noted that, in the technical solution of the present invention, the second logic gear set 30 has the same structure as the first logic gear set 20. In order to realize different logic controls of the first cam mechanism 40 and the second cam mechanism 50, it is only necessary to make corresponding direction adjustments to some structures of the second logic gear set 30 and the first logic gear set 20 that realize logic control.

[0033] like Figure 1 and Figure 2As shown, the first cam mechanism 40 includes a first cam 41 and a first slide 42. The first cam 41 is connected to the first logic gear set 20 by driving, and the first slide 42 is in contact with the first cam 41. The first slide 42 extends out along with the movement of the first cam 41. When in use, the first cam 41 is driven to rotate by the first logic gear set 20, and the protruding portion of the first cam 41 can drive the first slide 42 to extend. More preferably, in the technical solution of this embodiment, the first cam mechanism 40 includes a first elastic return member 43. The first elastic return member 43 is connected to the first slide 42 by driving, and the first elastic return member 43 drives the first slide 42 to retract along with the first cam 41. When in use, when the protruding portion of the first cam 41 leaves the first slide 42, the first elastic return member 43 can drive the first slide 42 to retract along with the first cam 41.

[0034] like Figure 2 As shown, in the technical solution of this embodiment, the second cam mechanism 50 has the same structure as the first cam mechanism 40. In order to realize different logical controls of the first cam mechanism 40 and the second cam mechanism 50, it is only necessary to make corresponding direction adjustments to the setting directions of the cams.

[0035] like Figure 1 As shown, in the technical solution of this embodiment, the double-station linkage switch also includes a housing 60, and the rotating driving member 10, the first logic gear set 20, the second logic gear set 30, the first cam mechanism 40 and the second cam mechanism 50 are installed in the housing 60. Specifically, as Figure 1 As shown, the housing 60 is divided into two parts, namely a gear box and a cam drive box, the driving gear 11, the first logic gear group 20 and the second logic gear group 30 are installed in the gear box, the rotating drive member 10 is installed on the gear box, and the first cam mechanism 40 and the second cam mechanism 50 are respectively installed on the cam drive box.

[0036] It should be noted that the above-mentioned rotating driving member 10 can be a motor, or a rotating cylinder or other components.

[0037] The present invention also provides a refrigerator, comprising a double-position linkage switch, wherein the double-position linkage switch is the above-mentioned double-position linkage switch. The double-position linkage switch can be applied to the control of the cold air door in the refrigerator, or to the electric control, or to the operation locking of the automatic lifting shelf of the refrigerator.

[0038] The present invention also provides an air conditioner, comprising a double-position linkage switch, wherein the double-position linkage switch is the above-mentioned double-position linkage switch. The double-position linkage switch can be applied to the control of the air door in the air conditioner, and can also be applied to the electric control components of the air conditioner.
