Therefore, the clamping between the micro switch 2 and the electric control box cover 1 is realized through the clamping between the mounting seat 23 and the mounting groove 11, the operation is convenient, the realization is easy, and the assembly efficiency is high.
When the mounting seat 23 is inserted into the mounting groove 11, the second buckles 231 are extruded by the first buckles 111 and begin to be folded, so that the included angle between the two second buckles 231 is reduced, after the mounting seat 23 is completely inserted into the mounting groove 11, the second buckles 231 are separated from extrusion of the first buckles 111, under the action of elastic force of elastic materials, the second buckles 231 start to expand until the second buckles 231 are abutted against the inner wall of the mounting groove 11, and at the moment, the end face of one end of each second buckle 231 is abutted against the end face of the larger end of each first buckle 111, the first buckles 111 and the second buckles 231 form clamping connection, so that the clamping connection between the mounting seat 23 and the mounting groove 11 is realized, and the clamping connection between the micro switch 2 and the electric control box cover 1 is also realized.

The connecting structure as described above, wherein the micro switch 2 includes a switch upright 21, and the switch upright 21 is slidably connected with the mounting seat 23.
Referring to fig. 4 and 5, the switch upright post 21 has a cylindrical structure, and the mounting seat 23 is sleeved on the switch upright post 21 and is close to one end of the switch upright post 21 fixed with the electric control box cover 1; the mounting seat 23 is clamped in the mounting groove 11 on the electric control box cover 1, no relative movement occurs, and the switch upright 21 can slide in the mounting seat 23.
Thus, the switch upright post 21 can flexibly slide in the mounting seat 23, so that the micro switch 2 can conveniently move downwards when being pressed or upwards when being sprung, and the micro switch 2 can be pressed or sprung, so that the operation is simple and convenient.
Further, the switch upright 21 is provided with a receiving cavity 213, and the mounting seat 23 is provided with a spring, and in the assembled state, the spring is disposed in the receiving cavity 213.
As shown in fig. 10, the switch upright post 21 is provided with an accommodating cavity 213 along the axial direction, the accommodating cavity 213 is of a circular groove structure, and a spring (all are drawn in the drawing) is fixedly connected to the mounting seat 23 and is arranged in the accommodating cavity 213, so that the switch upright post 21 is sleeved on the spring.
Therefore, the spring compression is utilized to generate rebound acting force to realize the bouncing of the micro switch 2, the structure is simple, the realization is easy, and the cost is low.
When the panel of the air conditioner is closed, the micro switch 2 is clamped between the electric control box cover 1 and the display box, and the display box presses the micro switch 2, and at the moment, the spring in the accommodating cavity 213 on the switch upright post 21 is compressed. In the process of disassembling the air conditioner, when the panel of the air conditioner is disassembled, the display box is disassembled along with the panel, the micro switch 2 is not pressed any more, the switch upright post 21 is sprung up under the rebound force of the spring, namely the micro switch 2 is sprung up, and the air conditioner is powered off.
The connecting structure as described above, wherein the switch upright 21 is provided with the sliding block 212, the mounting seat 23 is provided with the sliding slot 234 adapted to the sliding block 212, and the sliding block 212 can slide in the sliding slot 234.
As shown in fig. 8 and 9, the slider 212 is disposed at an end of the switch upright 21 far away from the end abutting against the display box, the shape of the sliding slot 234 on the mounting seat 23 is adapted to the shape of the slider 212, and the slider 212 can slide along the sliding slot 234.
Thus, the sliding connection of the switch upright 21 and the mounting seat 23 is realized by arranging the sliding block 212 and the sliding groove 234; meanwhile, the shape of the sliding groove 234 is matched with the shape of the sliding block 212, so that the sliding block 212 is not easy to fall off or deviate from the sliding groove in the sliding process, and the micro switch 2 can be normally sprung and pressed, so that the safety of the dismounting process is improved.
Further, as shown in fig. 10, the switch upright 21 is provided with a pressing rod 211, and an end of the pressing rod 211, which is far away from the slider 212, is hemispherical.
When the micro switch 2 is pressed or the micro switch 2 is sprung, the pressure lever 211 and the display box can generate relative motion, and the end part is hemispherical, so that the abutting surface of the pressure lever 211 and the display box is an arc surface, and the abutting area of the micro switch 2 and the display box is reduced.
In this way, the resistance of the end part of the switch upright post 21 and the display box during relative movement is reduced, so that the micro switch 2 can be easily pressed and sprung, and the process is smooth and the efficiency is high; meanwhile, compared with the press rod 211 with a cylinder structure, the manufacturing material of the micro switch 2 is saved, and the production cost is reduced.
In the above-mentioned connection structure, the slide block 212 is provided with the positioning groove 2121, the sliding groove 234 is provided with the positioning protrusion 233 matching with the positioning groove 2121, and when the micro switch 2 is sprung, the positioning groove 2121 slides along the positioning protrusion 233 in the sprung direction of the micro switch 2.

Since the mounting seat 23 is fixed in the mounting groove 11 of the electronic control box cover 1, the positioning protrusion 233 does not move when the micro switch 2 is sprung up, but the positioning groove 2121 slides along the positioning protrusion 233, so that the positioning protrusion 233 slides with respect to the positioning groove 2121.
In this way, the switch upright 21 is guided to be inserted into the mounting seat 23 by the cooperation between the positioning groove 2121 and the positioning protrusion 233, so that the assembly efficiency is improved, and the phenomenon that the switch upright is not mounted in place due to deviation during insertion is avoided.
Further, a plurality of positioning grooves 2121 are provided. That is, the positioning grooves 2121 are provided on a plurality of sides of the slider 212 to prevent erroneous mounting of the switch post 21.
The connecting structure as described above, wherein the depth of the sliding slot 234 is greater than the length of the slider 212.
The depth value of the sliding groove 234 refers to the dimension of the sliding groove 234 in the axial direction of the pressing bar 211, and also the dimension of the sliding groove 234 in the pop-up direction of the switch post 21, and similarly, the length value of the slider 212 refers to the dimension of the slider 212 in the axial direction of the pressing bar 211, or the dimension in the pop-up direction of the switch post 21. When the switch upright 21 is sprung up, the slider 212 moves up together with the switch upright, and if the depth value of the sliding slot 234 is smaller than the length value of the slider 212, the slider 212 is easily separated from the sliding slot 234, so that the reciprocating movement of the switch upright 21 in the sprung direction is affected.
In this embodiment, the depth value of the sliding slot 234 is set to be larger than the length value of the slider 212, so that the switch upright 21 can be prevented from being separated from the sliding slot 234 when bouncing, and the reciprocating movement of the micro switch 2 in the bouncing direction can be ensured.
The connecting structure as described above, wherein the micro switch 2 further includes a limiting plate 22, and the limiting plate 22 is clamped with the mounting seat 23 and adapted to limit the sliding displacement of the switch upright 21.
As shown in fig. 2, 11 and 12, the limiting plate 22 is sleeved on the switch upright 21 and is clamped with the mounting seat 23.
In this way, the switch post 21 can be further prevented from being separated from the mounting base 23 when bouncing up, and the pressing and bouncing up reciprocating movement of the micro switch 2 can be ensured.

As shown in fig. 12, the limiting plate 22 is provided with an insertion hole 222 through which the pressing rod 211 on the switch upright 21 passes, but the sliding block 212 cannot pass, the diameter of the insertion hole 222 is slightly larger than that of the pressing rod 211, the inner wall of the insertion hole 222 is provided with a plurality of protruding points 2221, and the protruding points 2221 are abutted with the outer surface of the pressing rod 211 of the switch upright 21. It should be noted that, since the pressing rod 211 has a cylindrical shape, and the cylinder has an upper bottom surface, a lower bottom surface, and side surfaces, the outer surface of the pressing rod 211 refers to the side surfaces of the cylinder.
In this way, the contact area between the pressing rod 211 and the insertion hole 222 is reduced by the bump 2221, which is equivalent to reducing the friction area of the pressing rod 211 in the reciprocating motion process in the bouncing direction, so that the friction resistance of the switch upright post 21 in the reciprocating motion process is reduced, and the pressing and bouncing processes of the switch upright post 21 are further ensured to be smooth.
The connection structure as described above, wherein the limiting plate 22 is provided with a T-shaped buckle 221, the mounting seat 23 is provided with a clamping block 232, and the T-shaped buckle 221 is clamped with the clamping block 232.

The T-shaped buckle 221 has two right-angle areas, and the clamping block 232 is clamped at the right-angle areas of the T-shaped buckle 221.
In this way, the T-shaped buckle 221 and the locking block 232 are provided to lock the limiting plate 22 to the switch column 21.
The connecting structure as described above, wherein the T-shaped buckle 221 is provided with a first guiding inclined plane 2211, and the mounting seat 23 is provided with a second guiding inclined plane 235, which is suitable for guiding the limiting plate 22 to be clamped on the mounting seat 23.
As shown in fig. 8, 12 and 13, the first guiding inclined plane 2211 is inclined on the T-shaped buckle 221, the second guiding inclined plane 235 is also inclined on the mounting seat 23, and the inclination angles of the first guiding inclined plane 2211 and the second guiding inclined plane 235 are the same. When the limiting plate 22 is clamped onto the mounting seat 23, the limiting plate 21 is accurately clamped onto the mounting seat 23 under the interaction of the first guide inclined surface 2211 and the second guide inclined surface 235 only by pushing the limiting plate 21 along the pressing direction of the switch upright 21 after the first guide inclined surface 2211 on the limiting plate 22 is aligned with the second guide inclined surface 235 on the mounting seat 23.
