[0041] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0042] In related technologies, the outdoor unit of an air conditioner has an internal circuit board control box, referred to as the "electrical control box," which is usually installed on the partition inside the outdoor unit. When the outdoor unit is working, the vibration generated by the compressor can easily be transmitted to the electrical control box through the partition, causing the solder joints of the electrical components on the electrical control box to crack, resulting in the failure of the electrical control box and a reduction in its service life.

[0043] Reference Figures 4 to 7 and combined Figure 1 According to the first aspect of the present invention, the electrical control assembly includes a partition plate 100, an electrical control box 200, and a buffer assembly 300. The partition plate 100 is used for connecting the housing of the outdoor unit of the air conditioner. The partition plate 100 is provided with a mounting groove 101. The electrical control box 200 is housed in the mounting groove 101. The electrical control box 200 includes a box body 210 and a circuit board 220. The circuit board 220 is disposed in the box body 210. The buffer assembly 300 is disposed between the partition plate 100 and the box body 210. The buffer assembly 300 is used to reduce the vibration of the partition plate 100 transmitted to the box body 210, thereby reducing the vibration of the electrical components on the circuit board 220 and improving the service life of the electrical control box 200.

[0044] Specifically, when the outdoor unit of the air conditioner is working, the vibration generated by the compressor is transmitted through the casing to the partition 100, and the vibration received by the partition 100 is transmitted to the housing 210. Since a buffer assembly 300 is provided between the partition 100 and the housing 210, the buffer assembly 300 can absorb the vibration, thereby reducing the transmission of the vibration of the partition 100 to the housing 210, and reducing the vibration received by the electrical components on the circuit board 220, thereby improving the service life of the electrical control box 200.

[0045] Reference Figures 7 to 10 and combined Figure 4 In some embodiments of this utility model, the buffer assembly 300 includes a first buffer 310 and a second buffer 320. The first buffer 310 is connected to one side of the box 210, and the second buffer 320 is connected to the other adjacent side of the box 210. The partition 100 includes a side plate 110 and a back plate 120 connected to the side plate 110. The side plate 110 and the back plate 120 together define a mounting groove 101. The side of the first buffer 310 away from the box 210 is connected to the side plate 110, and the side of the second buffer 320 away from the box 210 is connected to the back plate 120. This allows for all-around buffering of the box 210, thereby improving the buffering effect of the buffer assembly 300.

[0046] Specifically, the side panel 110 and the back panel 120 are arranged at an angle. The first buffer 310 is sandwiched between the side panel 110 and the box body 210. The first buffer 310 can reduce the vibration of the side panel 110 transmitted to the box body 210. The second buffer 320 is sandwiched between the back panel 120 and the box body 210. The second buffer 320 can reduce the vibration of the back panel 120 transmitted to the box body 210. It can buffer the box body 210 in all directions to improve the buffering effect of the buffer assembly 300.

[0047] It should be noted that the buffer component 300 can also be fitted around the outer periphery of the box 210. The buffer component 300 extends along the circumference of the box 210 and can buffer the box 210 in all directions. No limitation is made here.

[0048] Reference Figure 11 In some embodiments of this utility model, the first buffer 310 includes a first rubber layer 311, a second rubber layer 312, a first sponge layer 313, and a first adhesive layer 314. The first sponge layer 313 is sandwiched between the first rubber layer 311 and the second rubber layer 312. The first adhesive layer 314 is disposed on the side of the first rubber layer 311 away from the first sponge layer 313. The side of the first adhesive layer 314 away from the first rubber layer 311 is connected to the box body 210. The side of the second rubber layer 312 away from the first sponge layer 313 is connected to the side plate 110. On the one hand, this facilitates the assembly of the first buffer 310, and on the other hand, it improves the buffering effect of the first buffer 310.

[0049] Specifically, along the thickness direction of the first buffer 310, the first adhesive layer 314, the first rubber layer 311, the first sponge layer 313, and the second rubber layer 312 are stacked sequentially. The first adhesive layer 314 is bonded to the box body 210. Both the first rubber layer 311 and the second rubber layer 312 are elastic and can absorb the vibration of the side plate 110. Moreover, since the first sponge layer 313 is sandwiched between the first rubber layer 311 and the second rubber layer 312, and the first sponge layer 313 has a microporous structure, when the side plate 110 is vibrated, the first rubber layer 311 and the second rubber layer 312 can move closer to each other to further absorb the vibration of the side plate 110 and reduce the transmission of the vibration of the side plate 110 to the first rubber layer 311. On the one hand, this facilitates the assembly of the first buffer 310, and on the other hand, it improves the buffering effect of the first buffer 310.

[0050] Similarly, the second buffer 320 includes a third rubber layer 321, a fourth rubber layer 322, a second sponge layer 323, and a second adhesive layer 324. The second sponge layer 323 is sandwiched between the third rubber layer 321 and the fourth rubber layer 322. The second adhesive layer 324 is located on the side of the third rubber layer 321 away from the second sponge layer 323. The side of the second adhesive layer 324 away from the third rubber layer 321 is connected to the box body 210. The side of the fourth rubber layer 322 away from the second sponge layer 323 is connected to the back plate 120. On the one hand, this facilitates the assembly of the second buffer 320, and on the other hand, it improves the buffering effect of the second buffer 320.

[0051] It should be noted that the first buffer 310 or the second buffer 320 can also be replaced with elastic components such as compression springs, and no restrictions are imposed here.

[0052] In some embodiments of this utility model, the side plate 110 and the back plate 120 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the partition plate 100.

[0053] Specifically, the side plate 110 and the back plate 120 can be integrally formed by stamping, which can reduce the number of molds and reduce the production cost of the molds, thereby reducing the production cost of the partition plate 100.

[0054] Of course, in other specific embodiments, the side plate 110 and the back plate 120 can also be connected by welding, wherein the welding method includes, but is not limited to, resistance welding, laser welding or ultrasonic welding.

[0055] Refer to Figure 4. Figure 9 In some embodiments of this utility model, a first limiting structure is provided between the box body 210 and the side plate 110. The first limiting structure is used to restrict the box body 210 from moving along the thickness direction of the side plate 110. A second limiting structure is provided between the box body 210 and the back plate 120. The second limiting structure is used to restrict the box body 210 from moving along the thickness direction of the back plate 120. This can improve the installation stability of the electrical control box 200.

[0056] In some embodiments of this utility model, the first limiting structure includes a first limiting protrusion 211 disposed on the box body 210 and a limiting hole 111 disposed on the side plate 110. The first limiting protrusion 211 is spaced apart from the first buffer member 310. The first limiting protrusion 211 is at least partially accommodated in the limiting hole 111 and can abut against the limiting hole 111. On the one hand, it can restrict the movement of the box body 210 along the thickness direction of the side plate 110. On the other hand, it can improve the installation efficiency of the electrical control box 200.

[0057] Specifically, the first limiting protrusion 211 and the first buffer member 310 are spaced apart to form a first clearance groove. The periphery of the limiting hole 111 enters the first clearance groove. The first limiting protrusion 211 abuts against the periphery of the side of the limiting hole 111 away from the first buffer member 310. On the one hand, this can restrict the movement of the box 210 along the thickness direction of the side plate 110. On the other hand, it can improve the installation efficiency of the electrical control box 200.

[0058] It should be noted that the positions of the first limiting protrusion 211 and the limiting hole 111 can be interchanged, which will not be described in detail here.

[0059] As another implementation, the first limiting structure can also be a structure in which a hook and a slot cooperate, which will not be described in detail here.

[0060] Reference Figure 3 , Figure 9 In some embodiments of this utility model, the second limiting structure includes a second limiting protrusion 212 disposed on the box body 210. The second limiting protrusion 212 is spaced apart from the second buffer member 320. The second limiting protrusion 212 abuts against the side of the back plate 120 away from the second buffer member 320. On the one hand, it can restrict the movement of the box body 210 along the thickness direction of the back plate 120. On the other hand, it can improve the installation efficiency of the electrical control box 200.

[0061] Specifically, the second limiting protrusion 212 and the second buffer member 320 are spaced apart to form a second clearance groove. The upper end of the back plate 120 is accommodated in the second clearance groove. The side of the upper end of the back plate 120 away from the second buffer member 320 abuts against the second limiting protrusion 212, and the side of the upper end of the back plate 120 close to the second buffer member 320 abuts against the second buffer member 320. On the one hand, this can restrict the movement of the box 210 along the thickness direction of the back plate 120. On the other hand, it can improve the installation efficiency of the electrical control box 200.

[0062] It should be noted that the second limiting structure can also be a structure in which a limiting pin and a through hole cooperate. The limiting pin is located on the box body 210, and the through hole is located at the upper end of the back plate 120. The limiting pin is inserted into the through hole, which can also limit the movement of the box body 210 along the thickness direction of the back plate 120. This is not a limitation here.

[0063] Reference Figure 1 , Figure 2In some embodiments of this utility model, the box body 210 is connected to the partition plate 100 by fasteners 410, and the fasteners 410 are fitted with buffer springs 420. One end of the buffer springs 420 abuts against the partition plate 100, and the other end of the buffer springs 420 abuts against the nuts of the fasteners 410. On the one hand, this makes the box body 210 and the partition plate 100 a stable connection, making installation more convenient. On the other hand, by setting the buffer springs 420, the vibration of the partition plate 100 can be prevented from being directly transmitted to the fasteners 410, thereby improving the service life of the electrical control box 200.

[0064] Specifically, the fastener 410 is a bolt or screw, etc., which passes through the partition plate 100 and is threadedly connected to the housing 210. The buffer spring 420 is sleeved on the outer periphery of the fastener 410, and one end of the buffer spring 420 is connected to...

[0065] Reference Figure 9 In some embodiments of this utility model, the circuit board 220 is provided with heat dissipation fins 230, which pass through the housing 210 and the partition plate 100, thereby improving the heat dissipation effect of the circuit board 220, improving the heat dissipation performance of the air conditioner outdoor unit, and thus improving the service life of the air conditioner outdoor unit.

[0066] Reference Figure 1 , Figure 2 According to the second aspect of the present invention, the outdoor unit of the air conditioner includes the electrical control component of the first aspect of the present invention, which can reduce the vibration of the electrical components on the circuit board 220, thereby improving the service life of the electrical control box 200.

[0067] Specifically, when the outdoor unit of the air conditioner is working, the vibration generated by the compressor is transmitted through the casing to the partition 100, and the vibration received by the partition 100 is transmitted to the housing 210. Since a buffer assembly 300 is provided between the partition 100 and the housing 210, the buffer assembly 300 can absorb the vibration, thereby reducing the transmission of the vibration of the partition 100 to the housing 210, and reducing the vibration received by the electrical components on the circuit board 220, thereby improving the service life of the electrical control box 200.

[0068] It should be noted that the outdoor unit of the air conditioner includes a housing, a fan assembly and a compressor. The partition 100 is located inside the housing and connected to the bottom of the housing to divide the interior of the housing into a first space and a second space. The fan assembly is housed in the first space and the compressor is housed in the second space, which will not be described in detail here.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
