Therefore, the indicating mechanism can intuitively indicate the on-off state of the circuit through the cooperation among the first rotating disc cam, the first linkage rod, the first pressing mechanism and the first indicating part, so that an intuitively and reliable indicating mechanism can be provided for the switch.

The indicating mechanism and the switch provided in the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

At least one embodiment of the present disclosure provides an indication mechanism. Fig. 1 is a schematic structural diagram of an indication mechanism according to an embodiment of the disclosure.

As shown in fig. 1, the indicating mechanism 300 includes a first rotary cam 110, a first link lever 120, a first pressing mechanism 130, and a first indicating portion 140; the first dial cam 110 includes a first disc portion 111 and a first main boss portion 112 connected to the first disc portion 111; the first link 120 includes a first hinge portion 121, a first contact portion 122, and a first driving portion 123; the first hold-down mechanism 130 includes a first resilient end 131; the first indicating part 140 includes a first status flag 141 and a second status flag 142.

For example, the first and second status markers 141 and 142 may be labels or color bars of different colors. Of course, the embodiments of the present disclosure include, but are not limited to, that the first and second status markers may also be light emitting elements or reflective sheets that emit different colors of light.

As shown in fig. 1, one end of the first hinge part 121 is fixedly connected to the first contact part 122, and the other end of the first hinge part 121 is fixedly connected to the first driving part 123; that is, the first hinge portion 121 is located between the first contact portion 122 and the first driving portion 123, and fixedly connected to the first contact portion 122 and the first driving portion 123, respectively. The first link lever 120 is rotatable about the first hinge portion 121, and the first elastic end 131 is in contact with the first link lever 120 and configured to apply a pressing force to the first link lever 120 to bring the first contact portion 122 into contact with the first dial cam 110, and the first driving portion 123 is connected to the first indicating portion 140 and configured to drive the first and second status marks 141 and 142 of the first indicating portion 140 to change in position.

In the indicating mechanism provided by the embodiment of the disclosure, when the first rotating disc cam rotates, the first contact portion contacts with the first rotating disc cam, so that when the first main protruding portion contacts with the first contact portion, the first connecting rod is driven to rotate around the first hinge portion, the first driving portion is enabled to displace, and the positions of the first state mark and the second state mark of the first indicating portion are driven to change. When the housing accommodating the indicating mechanism is provided with a window exposing only one status marker, the user can see that the first status marker and the second status marker are switched when the positions of the first status marker and the second status marker are changed. Therefore, the indicating mechanism can intuitively indicate the on-off state of the circuit through the cooperation among the first rotating disc cam, the first linkage rod, the first pressing mechanism and the first indicating part, so that an intuitively and reliable indicating mechanism can be provided for the switch.

In some examples, as shown in fig. 1, the first hinge portion 121, the first contact portion 122, and the first driving portion 123 are integrally formed.

In some examples, as shown in fig. 1, the first disk portion 111 includes a first splined bore 111A and a first arcuate bore 111B, the first splined bore 111A being located in a center of the first disk portion 111, the first arcuate bore 111B being configured to receive a first drive needle. Therefore, the first driving needle can drive the first disc part to rotate, and the whole first rotating disc cam is driven to rotate.

In some examples, the first spline hole 111A is configured to be connected to a first breaking unit. The first rotary disc cam can drive the first breaking unit through the first spline hole to realize closing or opening of the first breaking unit; at the same time, the first rotating disc cam changes the positions of the first state mark and the second state mark of the first indicating part through the first linkage rod, so that the state of the first breaking unit is indicated at the same time. On the other hand, the first breaking unit may also position the first rotary disc cam through the first spline hole. It should be noted that, the first state identifier and the second state identifier may establish a corresponding relationship with the state of the first breaking unit in advance according to the need.

In some examples, as shown in fig. 1, the first disk portion 111 includes two first arc-shaped holes 111B, and the two first arc-shaped holes 111B are centrally symmetrical about a center of the first disk portion 111. On the one hand, the first rotating disk cam can be driven by two driving needles, so that the reliability and the durability can be improved, and on the other hand, the two first arc-shaped holes can balance the mass distribution of the first disk part.

In some examples, as shown in fig. 1, the indicating mechanism 300 further includes a second dial cam 210, a second linkage 220, a second pressing mechanism 230, and a second indicating portion 240; the second turntable cam 210 includes a second disk part 211 and a second main protrusion part 212 connected to the second disk part 211; the second link 220 includes a second hinge part 221, a second contact part 222, and a second driving part 223; the second hold-down mechanism 230 includes a second resilient end 231; the second indicator 240 includes a third status flag 241 and a fourth status flag 242.

For example, the third status marker 241 and the fourth status marker 242 may be different colored labels or colored bars. Of course, the embodiments of the present disclosure include, but are not limited to, that the first and second status markers may also be light emitting elements or reflective sheets that emit different colors of light.

For example, the first status identifier and the third status identifier may be color patches of a first color, and the second status identifier and the fourth status identifier may be color patches of a second color. For example, the first color is red and the second color is green. Thus, the user can intuitively observe the above-described status flag.

As shown in fig. 1, one end of the second hinge part 221 is fixedly connected to the second contact part 222, the other end of the second hinge part 221 is fixedly connected to the second driving part 223, and the second link 220 is rotatable around the second hinge part 221; the second elastic end 231 contacts the second link 220 and is configured to apply a pressing force to the second link 220 to bring the second contact portion 222 into contact with the second dial cam 210, and the second driving portion 223 is connected to the second indicating portion 240 and is configured to drive the positions of the third state flag 241 and the fourth state flag 242 of the second indicating portion 240 to change.

In the indicating mechanism provided by the embodiment of the disclosure, similar to the first turntable cam, the first linkage rod, the first pressing mechanism and the first indicating portion, when the second turntable cam rotates, the second main protrusion portion contacts with the second turntable cam, so that the second linkage rod is driven to rotate around the second hinge portion when the second main protrusion portion contacts with the second contact portion, the second driving portion is caused to displace, and the positions of the third state mark and the fourth state mark of the second indicating portion are driven to change. When the housing accommodating the indicating mechanism is provided with a window exposing only one state mark, the user can see that the third state mark and the fourth state mark are switched when the positions of the third state mark and the fourth state mark are changed. Therefore, the indicating mechanism can intuitively indicate the on-off state of the circuit through the cooperation among the second turntable cam, the second linkage rod, the second pressing mechanism and the second indicating part, so that an intuitively and reliable indicating mechanism can be provided for the switch.

On the other hand, the indicating mechanism can also indicate the on-off of the two circuits through the first indicating part and the second indicating part. Of course, the embodiment of the disclosure includes, but is not limited to, that the indication mechanism can be provided with more indication parts and driving mechanisms connected with the indication parts according to actual needs; other indicators and drive mechanisms may be seen in the design of the first turntable cam, the first linkage rod, the first hold-down mechanism and the first indicator.

In some examples, as shown in fig. 1, the second hinge portion 221, the second contact portion 222, and the second driving portion 223 are integrally formed.

In some examples, as shown in fig. 1, the second disk portion 211 includes a second splined bore 211A and a second arcuate bore 211B, the second splined bore 211A being located in a center of the second disk portion 211, the second arcuate bore 211B being configured to receive a second drive needle. Therefore, the second driving needle can drive the second disc part to rotate, so that the whole second turntable cam is driven to rotate.

In some examples, the second splined bore 211A is configured to connect with a second breaking unit. The second rotary table cam can drive the second breaking unit through the second spline hole, so that the closing or opening of the second breaking unit is realized; meanwhile, the second rotary table cam changes the positions of the third state mark and the fourth state mark of the second indicating part through the second linkage rod, so that the states of the second breaking units are indicated at the same time. Alternatively, the second breaking unit may also position the second turntable cam through the second splined hole. It should be noted that, the third state identifier and the fourth state identifier may establish a corresponding relationship with the state of the second breaking unit in advance according to the need.

In some examples, as shown in fig. 1, the second disk portion 211 includes two second arc-shaped holes 211B, the two second arc-shaped holes 211B being centrally symmetrical about a center of the second disk portion 211. On the one hand, the second turntable cam can be driven by two driving needles, so that the reliability and the durability can be improved, and on the other hand, the two second arc-shaped holes can balance the mass distribution of the second disc part.

In some examples, as shown in fig. 1, the first pressing mechanism 130 and the second pressing mechanism 230 are integrated into one pressing mechanism, and the first elastic end 131 and the second elastic end 231 are two elastic ends of the pressing mechanism, respectively, so that one pressing mechanism can be saved, and the structure of the whole indicating mechanism is more compact.

As shown in fig. 2, the indication mechanism 300 further includes a first micro-switch 350 and a second micro-switch 360; the first micro switch 350 is located at a side of the first rotating disc cam 110 away from the first linkage 120; the second micro switch 360 is located at a side of the second turntable cam 210 away from the second linkage 220; the first dial cam 110 further comprises a first sub-lobe 113 and the second dial cam 220 further comprises a second sub-lobe 223, the first sub-lobe 113 being configured to activate the first micro-switch 350 and the second sub-lobe 223 being configured to activate the second micro-switch 360.

In the indicating mechanism, a first rotating disc cam can trigger a first micro switch through a first auxiliary protruding part to convert a closing or opening state of a first breaking unit into an electric signal and send the electric signal to a controller; simultaneously, the first rotating disc cam changes the positions of the first state mark and the second state mark of the first indicating part through the first connecting rod, so that the state of the first breaking unit is intuitively indicated at the same time; the second rotary table cam can trigger the second micro switch through the second auxiliary protruding part to convert the closing or opening state of the second breaking unit into an electric signal and send the electric signal to the controller; at the same time, the second rotary table cam changes the positions of the third state mark and the fourth state mark of the second indicating part through the second linkage rod, so that the states of the second breaking units are also intuitively indicated.

In some examples, as shown in fig. 2, the indication mechanism 300 further includes a housing 310; the housing 310 includes a first recess 311 and a second recess 312; the first turntable cam 110 is at least partially disposed in the first recess 311 and the second turntable cam 210 is at least partially disposed in the second recess 312.
