DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0034] In order to solve the technical problem that the loosening of the nut 5 changes the center of gravity of the fan 4, which significantly increases the power consumption in the long run, as shown in Figures 1-8 the following preferred technical solutions are provided:

[0035] As shown in Figures 1-2 the fan mounting mechanism of the air conditioner, which comprises a cabinet 1 and a mounting seat 2 fixed inside the cabinet 1. The mounting seat 2 is first fixed in the pre-set position inside the cabinet 1 by welding to ensure that the mounting seat 2 is flat and has no looseness with the cabinet 1. Four screw rods 3 are evenly installed on one side of the mounting seat 2. The fan 4 is in contact with one side of the mounting seat 2, and the fan 4 is in sliding connection with the four screw rods 3 through four mounting ear plates. On the designated side of the mounting seat 2, four screw rods 3 are installed according to the uniform distribution principle, such as rectangular four-corner layout. The screw rods 3 are fixed with the mounting seat 2 by welding to ensure that the screw rods 3 are perpendicular to the plane of the mounting seat 2, and the axes of the four screw rods 3 are parallel and the spacing matches the hole diameter of the mounting ear plate of the fan 4. The four mounting ear plates of the fan 4 are respectively aligned with the four screw rods 3, and the fan 4 is pushed along the axis direction of the screw rod 3 to make the fan 4 close to the mounting seat 2 and in contact with the surface of one side of the mounting seat 2.

[0036] The screw 3 is screwed with a nut 5, and the nut 5 is in contact with the mounting lug plate of the fan 4. In the part of each screw 3 extending out of the mounting lug plate of the fan 4, the nut 5 is screwed in. By rotating the nut 5, the nut 5 is in close contact with the surface of the mounting lug plate of the fan 4. The nut 5 is continuously screwed until the fan 4 is firmly fixed on the mounting seat 2. Two housings 6 are mounted on one side of the mounting seat 2. The two housings 6 are fixed on the mounting seat 2 by bolts. The two housings 6 can be conveniently disassembled and installed. The nut 5 is slidably connected with a fixing clamp 7. One end of the fixing clamp 7 is hingedly connected with a connecting piece 8. The connecting piece 8 is arranged in the housing 6. Two moving seats 9 are slidably connected in the housing 6. One end of the connecting piece 8 is rotatably connected with the moving seat 9. A frame plate 10 is penetrated through one side of the housing 6. The two moving seats 9 are in contact with the frame plate 10. Two elastic extrusion pieces 20 are slidably connected in the frame plate 10.

[0037] The two moving seats 9 in the housing 6 are symmetrically distributed at the initial position. The connecting piece 8 is horizontal, and is not deflected under stress. The frame plate 10 keeps the position fixed through the penetrating hole of the housing 6. The two elastic extrusion pieces 20 in the frame plate 10 are in a natural stretching state, and are not extruded and deformed. One end of each of the two elastic extrusion pieces 20 is in contact with the two moving seats 9. When the moving seat 9 moves, the elastic extrusion piece 20 is pushed, so that the elastic extrusion piece 20 moves downward. One end of the elastic extrusion piece 20 is fixedly installed with an expansion piece 30. Two groups of elastic heat conduction pieces 40 are arranged on one side of the frame plate 10. When the fan 4 operates, heat is generated, which is about 50-60℃. After the fan 4 is offset due to loose bolts, additional energy consumption is caused, so that the surface temperature of the fan 4 is further increased to 80-100℃. The heat is quickly transferred to the expansion piece 30 through the elastic heat conduction piece 40. When the temperature of the expansion piece 30 reaches a preset threshold value, the expansion piece 30 is significantly expanded.

[0038] In the initial state, the nut 5 is closely attached to the mounting lug plate of the fan 4. The fixing clamp 7 is sleeved on the surface of the nut 5 and remains stationary. At this time, the moving seat 9 and the frame plate 10 in the housing 6 are at the initial position. The elastic extrusion piece 20 is not extruded. The expansion piece 30 and the elastic heat conduction piece 40 are in a separated state. The elastic heat conduction piece 40 does not contact the surface of the fan 4. The whole mechanism is not subjected to external force, and is only maintained stable by the initial pre-tightening force. When the fan 4 operates and vibrates or the temperature changes, the nut 5 is slightly rotated relative to the screw 3 and is displaced away from the mounting lug plate. Since the fixing clamp 7 is slidably connected with the nut 5, the rotation and displacement of the nut 5 will drive the fixing clamp 7 to be deflected synchronously, and then drive the hingedly connected connecting piece 8 to move in the housing 6.

[0039] When the nut 5 is loosened, a slight rotation or displacement will occur, and through the connection of the fixing clamp 7 and the nut 5, the slight movement can be transmitted to the connecting piece 8. The displacement of the connecting piece 8 is designed in a similar lever principle, which can convert the slight displacement of the loosening into a significant action sufficient to push the moving seat 9. When the connecting piece 8 moves, the other end drives the moving seat 9 to slide in the shell 6. When the moving seat 9 moves, it will push the elastic extrusion piece 20 to move downward. The elastic extrusion piece 20 is deformed by the extrusion of the moving seat 9, and at the same time, it pushes the expansion piece 30 to approach the elastic heat conducting piece 40, so that the expansion piece 30 contacts the elastic heat conducting piece 40, and finally the elastic heat conducting piece 40 contacts the surface of the fan 4. After the elastic heat conducting piece 40 contacts the surface of the fan 4, the heat generated by the operation of the fan 4 is transmitted to the expansion piece 30. The expansion piece 30 expands by heat, generates a reverse thrust acting on the elastic extrusion piece 20, and pushes the moving seat 9 to slide reversely. Through the connecting piece 8, the fixing clamp 7 is reversely rotated, and the reverse rotation of the fixing clamp 7 acts on the surface of the nut 5 to re-tighten the loosened nut 5 until the nut 5 and the mounting lug plate are in close contact.

[0040] After the nut 5 is tightened, the fixing clamp 7 is no longer stressed, and under the action of the elastic extrusion piece 20, the moving seat 9 and the frame plate 10 are reset, the expansion piece 30 is separated from the elastic heat conducting piece 40, the elastic heat conducting piece 40 is separated from the surface of the fan 4, the expansion piece 30 is cooled and shrinks, and the whole mechanism returns to the initial state, waiting for the next loosening trigger. Therefore, there is no need for manual inspection or operation. The whole process from the loosening detection of the nut 5 to the re-tightening of the nut 5 is completed by the mechanism itself. Even in a closed cabinet 1, the loosening problem can be responded in time, the fan 4 failure caused by the loosening of the nut 5 can be reduced, and the running efficiency of the fan 4 can be maintained. After the nut 5 is loosened, the re-tightening can be completed in a short time to avoid the imbalance of the center of gravity caused by the deviation of the fan 4, thereby reducing the increase of power consumption caused by the loosening of the nut 5, and achieving the effect of energy saving.

[0041] As shown in Figures 5-6 Two limiting grooves 61 are provided on one side of the shell 6, and a fixed plate 62 is installed inside the shell 6 in correspondence. The first supporting rod 63 is fixedly installed on one side of the fixed plate 62, and the second supporting rod 64 is installed inside the shell 6 in correspondence. The limiting grooves 61 can play a limiting role and limit the movement of the moving seat 9. The first supporting rod 63 and the second supporting rod 64 can play a connecting role.

[0042] The connecting piece 8 comprises a first connecting rod 81 and a second connecting rod 82 rotatably connected at one end of the first connecting rod 81, one end of the first connecting rod 81 is hingedly connected with the fixed clamp 7, and the first connecting rod 81 is rotatably connected with the second supporting rod 64, the second connecting rod 82 is slidably connected with the first supporting rod 63, and the slight loosening of the nut 5 is transmitted by the deflection of the fixed clamp 7, the rotation of the first connecting rod 81 and the sliding of the second connecting rod 82 in stages, and is enlarged as a macroscopic displacement of the moving seat 9, which ensures that the subsequent elastic heat guide piece 40 can reliably contact the fan 4.

[0043] The moving seat 9 comprises a vertical plate 91 and a T-shaped block 92 fixed at one end of the vertical plate 91, the T-shaped block 92 is slidably connected with the limiting groove 61, and the T-shaped block 92 moves inside the limiting groove 61, which can limit the movement of the vertical plate 91 and ensure the stable movement of the vertical plate 91, a rotating shaft 93 is fixedly installed inside the vertical plate 91, one end of the second connecting rod 82 is rotatably connected with the rotating shaft 93, and an inclined surface 94 is formed at one end of the vertical plate 91, the T-shaped block 92 is slidably connected with the limiting groove 61 on the inner wall of the shell 6, and the T-shaped structure can prevent the vertical plate 91 from disengaging from the limiting groove 61 during sliding, thereby ensuring that the moving direction is always along the horizontal track of the limiting groove 61.

[0044] As shown in Figures 7-8 The connecting shell 101 is fixedly installed inside the frame plate 10, which can limit the movement of the elastic extrusion piece 20 and ensure that the elastic extrusion piece 20 always moves vertically.

[0045] The elastic extrusion piece 20 comprises an inclined surface plate 201 and a plurality of rolling shafts 202 rotatably connected at one end of the inclined surface plate 201, the inclined surface plate 201 is slidably connected with the connecting shell 101, the rolling shafts 202 are in contact with the inclined surface 94, a first positioning plate 203 is fixedly installed on the surface of the inclined surface plate 201, a horizontal plate 204 is installed at the other end of the inclined surface plate 201, a first spring 205 is fixedly installed on one side of the first positioning plate 203, one end of the first spring 205 is fixedly connected with the connecting shell 101, the inclined surface plate 201 is slidably connected with the connecting shell 101 of the frame plate 10, the rolling shafts 202 on the surface thereof are in slight contact with the inclined surface 94 of the moving seat 9 but are not extruded, the first spring 205 on one side of the first positioning plate 203 is in a natural stretching or slightly compressed state, and the first positioning plate 203 is positioned at the initial position of the connecting shell 101 through the elastic force, the expansion piece 30 on one side of the horizontal plate 204 maintains a predetermined gap with the elastic heat guide piece 40 and does not transmit a force signal, when the nut 5 is loosened to drive the fixed clamp 7 to deflect, the vertical plate 91 slides along the limiting groove 61, the inclined surface 94 thereof is in contact with the rolling shafts 202 and applies pressure, since the rolling shafts 202 can freely rotate, the friction between the inclined surface 94 and the rolling shafts 202 is rolling friction, the horizontal thrust of the inclined surface plate 201 can be almost losslessly transmitted to the inclined surface plate 201, and the inclined surface plate 201 will move downward.

[0046] At this time, the first positioning plate 203 moves synchronously with the inclined plate 201, compresses the first spring 205 to generate elastic potential energy, reserves power for subsequent reset, and the expansion piece 30 is in contact with the elastic heat conducting piece 40 under the thrust of the horizontal plate 204, and finally makes the elastic heat conducting piece 40 closely contact with the surface of the fan 4. The heat of the fan 4 is transmitted to the expansion piece 30 through the elastic heat conducting piece 40. The expansion piece 30 is heated and expanded to generate a thrust, which acts on the horizontal plate 204 and pushes the inclined plate 201 to slide towards the vertical plate 91. At the same time, the first spring 205 releases the elastic potential energy to assist the reset of the inclined plate 201.

[0047] The expansion piece 30 includes a memory alloy 301 and a heat conducting block 302 fixed on one side of the memory alloy 301. The memory alloy 301 is fixedly connected with the horizontal plate 204. The memory alloy 301 is a nickel-titanium-based memory alloy 301, and the phase transition temperature is set to 60-80℃. Although the fan 4 generates heat of 50-60℃ during normal operation, the heat can only be transmitted through the air because the heat conducting block 302 is not in contact with the elastic heat conducting piece 40, and the transmission efficiency is extremely low. The memory alloy 301 cannot obtain enough heat to reach the phase transition temperature of 60-80℃, and always maintains a low-temperature contraction state to avoid false expansion when there is no loosening. The memory alloy 301 only absorbs heat when it is in contact, completely eliminates the risk of false triggering when there is no loosening, reduces energy waste, improves the driving efficiency of the memory alloy 301, and consumes specific heat latent heat during phase transition expansion of the memory alloy 301. If the heat conducting block 302 is in long-term contact with the elastic heat conducting piece 40, the memory alloy 301 will continuously absorb the heat generated during normal operation of the fan 4 even if there is no loosening, which may cause slow expansion at low temperature, waste energy and shorten the service life of the memory alloy 301. The non-contact design makes the memory alloy 301 only absorb heat when it needs to reset, avoids invalid energy consumption, and at the same time ensures that enough heat can be obtained for each expansion to generate sufficient thrust to complete the reset, thereby improving the driving efficiency.

[0048] The elastic heat conducting piece 40 includes a heat conducting rod 401 and a second positioning plate 402 fixed on the surface of the heat conducting rod 401. The heat conducting rod 401 is slidably connected with the frame plate 10 and the connecting shell 101. A heat conducting plate 403 is fixedly installed at one end of the heat conducting rod 401, and the heat conducting plate 403 is slidably connected with the connecting shell 101. A second spring 404 is fixedly installed on one side of the second positioning plate 402, and one end of the second spring 404 is fixedly connected with the frame plate 10. In the initial state, the second spring 404 is in a natural stretched state, and the second positioning plate 402 is pushed by the elastic force to make the heat conducting rod 401 drive the heat conducting plate 403 to retract into the connecting shell 101. At this time, the heat conducting plate 403 has a gap with the surface of the fan 4, and one end of the heat conducting rod 401 is also in a separated state with the heat conducting block 302, forming a double non-contact heat blocking structure. The double physical spacing ensures that even if the temperature of the cabinet 1 fluctuates, the memory alloy 301 cannot obtain enough heat, and the risk of false triggering when there is no loosening is completely eliminated.

[0049] In order to solve the technical problem that the nut 5 may not be tightened in place, as shown in the drawings, the following preferred technical solutions are provided: Figures 3-4

[0050] A first circular frame 21 is fixedly installed inside the mounting seat 2, and an annular electromagnet 22 is fixedly installed on one side of the first circular frame 21. A circular plate 23 is fixedly installed inside the mounting seat 2, and an annular pressure sensor 24 is fixedly installed on one side of the circular plate 23. One end of the fan 4 is in contact with the annular pressure sensor 24. The annular pressure sensor 24 is electrically connected with the annular electromagnet 22 through a controller. The controller is prior art and not shown in the drawings. The annular pressure sensor 24 is in full contact with one end of the fan 4. Its detection area is annularly distributed, which can be understood as splitting the annular pressure sensor 24 into multiple independent detection units, or identifying a “pressure missing area” through a pressure distribution algorithm. When the fan 4 is separated from the annular pressure sensor 24 in a certain direction (such as the upper right side) due to loosening of the nut 5, the annular pressure sensor 24 can directly locate the pressure disappearance on the upper right side, rather than only detecting a decrease in overall pressure.

[0051] A second circular frame 41 is fixedly installed on one end of the fan 4, and an annular magnet block 42 is fixedly installed on one side of the second circular frame 41. When the fan 4 is separated from the annular pressure sensor 24 in a certain direction (such as the upper right side) due to loosening of the nut 5, the controller (the controller is prior art and not shown in the drawings) activates the electromagnet coil of the annular electromagnet 22 corresponding to the loosening position signal, and attracts the annular magnet block 42 through a directional magnetic attraction force, so as to pull back the loosening part, thereby providing more reliable cooperation for tightening of the nut 5 and enabling the nut 5 to be tightened in place.
