Detailed implementation manner

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0040] The traditional electronic control box uses two separate components, namely a base and a top cover, which are matched and fixed together by screws or buckles to enclose the circuit board inside, providing protection such as insulation and moisture-proof for the internal circuit board. Since the traditional electronic control box has two separate components, two sets of corresponding molds need to be opened, resulting in a relatively high mold cost. Moreover, the two materials can only be used in combination, and the storage, transportation, and assembly of the two materials are all inconvenient, bringing great trouble to the manufacturer. Therefore, the present utility model proposes an electronic control box for an air conditioner.

[0041] Please refer to Figure 1 、 Figure 2 and Figure 4 In an embodiment of the present utility model, the electronic control box 100 for an air conditioner includes a base part 1, a top cover part 2, and a connecting part 3. The base part 1 has an installation cavity 11 for accommodating the circuit board. The base part 1, the top cover part 2, and the connecting part 3 are integrally formed, and the connecting part 3 is arranged between the base part 1 and the top cover part 2. The top cover part 2 is rotatable relative to the base part 1 to close the installation cavity 11 on the base part 1, thereby protecting the circuit board in the installation cavity 11.

[0042] Specifically, the electronic control box 100 includes a top cover part 2, a connecting part 3, and a base part 1 that are integrally connected in sequence. The base part 1 has an installation cavity 11 for accommodating the circuit board. In the flat and unfolded state, the base part 1 and the top cover part 2 are placed at intervals on a plane, and the connecting part 3 is located between the base part 1 and the top cover part 2. At this time, the base part 1 and the top cover part 2 are at 180 degrees, and the installation cavity 11 of the base part 1 is exposed to the outside, facilitating the user to install the circuit board in the installation cavity 11. One end of the connecting part 3 facing the base part 1 is integrally connected to one end of the base part 1, and one end of the connecting part 3 facing the top cover part 2 is integrally connected to the top cover part 2.

[0043] In this embodiment, the base part 1, the top cover part 2, and the connecting part 3 of the electronic control box 100 are integrally formed, and specifically, they can be made by injection molding. Among them, the connecting part 3 has a certain toughness and can be bent under the action of external force. During use, after the user fixes the circuit board in the installation cavity 11 of the base part 1, the installation cavity 11 of the base part 1 is then closed to protect the internal circuit board. When closing the installation cavity 11, the top cover part 2 is rotated relative to the base part 1 along the connecting part 3 so that the top cover part 2 closes the installation cavity 11. During the rotation of the top cover part 2, the connecting part 3 will undergo a bending deformation from a flat state, so that the top cover part 2 and the base part 1 are in a superimposed state. During the relative rotation of the top cover part 2 and the base part 1, the connecting part 3 is always integrally connected to the base part 1 and the top cover part 2.

[0044] This application provides an electric control box 100 with an integrally rotatable structure. By providing a base part 1 and a top cover part 2 that are integrally formed, only one set of molds needs to be opened. Compared with the two sets of molds in the traditional solution, the cost of the molds is reduced, and the storage and maintenance of the molds are also more convenient. If there are two sets of molds, when replacing the molds on the injection molding machine later, it is necessary to ensure that the molds on both injection molding machines are of the correct model before production can be carried out. However, this application only has one set of molds, greatly simplifying the subsequent production, storage, maintenance and other operations of the molds. Moreover, by making the base part 1 and the top cover part 2 into an integral part, one part number can represent the electric control box 100, greatly simplifying the material management. Compared with the two materials in the traditional method, this application does not require matching the two materials as in the traditional method, facilitating the access of the materials. The top cover part 2 of the electric control box 100 can rotate relative to the base part 1. Since both ends of the connecting part 3 are always integrally connected to the top cover part 2 and the base part 1, one side of the connecting part does not need to be fixed again. Only the end far from the connecting part 3, that is, only the movable end, needs to be fixed to complete the assembly of the electric control box 100, simplifying the assembly procedure of the electric control box 100; only the movable end needs to be disassembled during disassembly, reducing the disassembly process; if there is an abnormality in the circuit board later, it is also convenient for subsequent maintenance operations. It should be noted that after a large number of experimental verifications, only fixing the side far from the connecting part 3 in this application can ensure that the electric control box 100 passes the dampness test.

[0045] Please refer to Figures 2 - 5 As shown, the connecting part 3 includes a first extension part 31, a transition part 32 and a second extension part 33 that are connected in sequence. The transition part 32 can deform as the top cover part 2 rotates relative to the base part 1.

[0046] Specifically, the connecting part 3 includes a first extension part 31, a transition part 32 and a second extension part 33. The transition part 32 is arranged between the first extension part 31 and the second extension part 33. One end of the first extension part 31 is integrally connected to the base part 1, and the other end is integrally connected to one end of the transition part 32; one end of the second extension part 33 is integrally connected to the top cover part 2, and the other end is connected to the other end of the transition part 32. When the top cover part 2 rotates relative to the base part 1, the transition part 32 deforms, so that the top cover part 2 can be converted from the unfolded state to the stacked state; or from the stacked state to the unfolded state, thereby realizing the state conversion of opening or closing. During the process of the top cover part 2 rotating relative to the base part 1, the first extension part 31 moves synchronously with the base part 1, and the second extension part 33 moves synchronously with the top cover part 2. The deformation position only occurs in the transition part 32 to ensure accurate alignment and effective closure of the top cover part 2 and the base part 1 in the closed state.

[0047] In this embodiment, the length of the first extension portion 31 in the width direction of the base portion 1 is less than the width of the base portion 1, and the length of the second extension portion 33 in the width direction of the top cover portion 2 is less than the width of the top cover portion 2. This structural design is used to reduce raw materials, thereby reducing the material cost. In some alternative embodiments, the length of the first extension portion 31, the length of the second extension portion 33, and the length of the transition portion 32 in the width direction of the base portion 1 are the same, and the length of the first extension portion 31 in the width direction of the base portion 1 is 1 / 3 - 1 / 2 of the width of the base portion 1.

[0048] As Figure 4 and Figure 5 shown, the junction of the first extension portion 31 and the transition portion 32 gradually thins in the direction towards the transition portion 32. And / or, the junction of the second extension portion 33 and the transition portion 32 gradually thins in the direction towards the transition portion 32.

[0049] Specifically, in order to further ensure that the deformation position of the electric control box 100 occurs at the transition portion 32, a certain slope is provided at the junction of the first extension portion 31 and the transition portion 32, that is, the wall thickness at the junction of the first extension portion 31 and the transition portion 32 smoothly transitions, and the wall thickness at the junction gradually decreases in the direction towards the transition portion 32, but the wall thickness at the minimum is not less than the wall thickness of the transition portion 32. Similarly, a certain slope is also provided at the junction of the second extension portion 33 and the transition portion 32.

[0050] As Figure 3 shown, the length of the transition portion 32 in the direction from the first extension portion 31 to the second extension portion 33 (hereinafter referred to as the width of the transition portion 32) is in the range of 1 - 20 mm; and / or the thickness of the transition portion 32 is in the range of 0.2 - 1.5 mm. In another alternative embodiment, the width of the transition portion 32 is in the range of 1 - 5 mm, preferably 1 mm. The wall thickness range of the transition portion 32 is 0.2 - 0.8 mm, preferably 0.3 mm. During actual use, if the width of the transition portion 32 is too large, it will cause the electric control box 100 on one side of the transition portion 32 to not close tightly, thereby causing the sealing and fixing of the electric control box 100 to fail. The wall thickness of the transition portion 32 is an important parameter to ensure the position where the bending deformation occurs, that is, to ensure that the bending occurs at the connection portion, and to ensure the mechanical strength and toughness of the transition portion 32 to achieve the effect of long-term use of the electric control box 100.

[0051] As Figure 1 、 Figure 6 and Figure 7As shown, at one end of the base part 1 away from the connecting part 3, a first buckle 12 is provided, and at one end of the top cover part 2 away from the connecting part 3, a first fixing buckle hole 21 is provided. The first buckle 12 matches the first fixing buckle hole 21. Here, the matching means that when the top cover part 2 rotates to close the base part 1, the first buckle 12 is directly opposite the first fixing buckle hole 21, and the size of the first buckle 12 is adapted to the size of the first fixing buckle hole 21, so as to ensure that the first buckle 12 can be buckled into the first fixing buckle hole 21, thereby fixing one end of the top cover part 2 and the base part 1 away from the connecting part 3. The number of the first buckle 12 and the first fixing buckle hole 21 is the same. The number of the first fixing buckle holes 21 can be set to two, and the two first fixing buckle holes 21 are respectively arranged at both ends in the width direction of the top cover part 2. Of course, the position of the first fixing buckle hole 21 can also be set at other positions, which can be set according to actual needs and will not be limited here. In this application, one end of the connecting part 3 does not need to be fixed. When the top cover part 2 rotates relative to the base part 1, the top cover part 2 closes the installation cavity 11 of the base part 1. At this time, only the side away from the connecting part 3 needs to be fixed. Therefore, during the assembly of this application, only one end needs to be assembled, which can reduce the assembly steps of one end, facilitate installation and disassembly, and is beneficial to subsequent maintenance operations.

[0052] As Figures 1 - 3 shown, at one end of the base part 1 away from the connecting part 3, a first fixed mounting hole 13 is provided, and at one end of the top cover part 2 away from the connecting part 3, a second fixed mounting hole 22 adapted to the first fixed mounting hole 13 is provided; and / or, on the first extension part 31, there is a third fixed mounting hole 311, and on the second extension part 33, there is a fourth fixed mounting hole 331 adapted to the second fixed mounting hole 22.

[0053] Specifically, although the first fixing buckle hole 21 and the first buckle 12 are provided on the electric control box 100 to buckle the base part 1 and the top cover part 2, after long-term use or under the action of external force, the buckling function of the first fixing buckle hole 21 and the first buckle 12 for buckling the base part 1 and the top cover part 2 may fail. Therefore, the first fixed mounting hole 13 and the second fixed mounting hole 22 are preset in advance. When in long-term use and the buckling of the first fixing buckle hole 21 and the first buckle 12 fails, the base part 1 and the top cover part 2 are fixed by screwing through the first fixed mounting hole 13 and the second fixed mounting hole 22. Similarly, the cooperation on one side of the connecting part 3 may also fail. The third fixed mounting hole 311 and the fourth fixed mounting hole 331 are respectively provided on the first extension part 31 and the second extension part 33 to ensure the stable cooperation between the two sides of the connecting part 3. It should be noted that the above features can normally be not used and can be used when the cooperation between the base part 1 and the top cover part 2 fails.

[0054] Please refer to Figure 1, there are multiple fixing structures arranged in the installation cavity 11 of the base part 1, and these fixing structures are used to fix the circuit board in the installation cavity 11. The fixing structures can include a circuit board fixing buckle 14 and a circuit board fixing elastic buckle 15, and the circuit board fixing buckle 14 and the circuit board fixing elastic buckle 15 are used to fix the circuit board. The positions and quantities of the circuit board fixing buckle 14 and the circuit board fixing elastic buckle 15 are set according to actual needs and are not limited herein.

[0055] Specifically, the circuit board fixing buckle 14 and the circuit board fixing elastic buckle 15 are arranged at intervals. For example, the circuit board fixing buckle 14 is correspondingly arranged at one end in the length direction of the circuit board, and the circuit board fixing elastic buckle 15 is correspondingly arranged at the other end in the length direction of the circuit board. During installation, first insert one end of the circuit board into the circuit board fixing buckle 14 to fix one end of the circuit board first, and then use the circuit board fixing elastic buckle 15 to fix the other end of the circuit board. This structure is convenient for installation and also convenient for disassembly, which is beneficial for subsequent circuit board replacement or maintenance. In another alternative embodiment, the circuit board can also be fixed by screws, and the screw fixing method can also achieve disassembly and can also facilitate subsequent replacement or maintenance. Of course, the circuit board fixing method can also adopt other structures as long as the circuit board can be stably fixed in the installation cavity 11 of the base part 1.

[0056] As Figure 1 and Figure 9 shown, the base part 1 further includes a wire outlet groove 16, and the wire outlet groove 16 communicates the installation cavity 11 with the outside. A protruding part 23 is arranged at the position of the top cover part 2 corresponding to the wire outlet groove 16. At least one wire arranging elastic buckle 17 is also arranged in the installation cavity 11, and the wire arranging elastic buckle 17 is used to fix the cable. The wire outlet groove 16 is for the cable to extend out of the outside to connect to the mains. A sealing member 4 is arranged in the wire outlet groove 16, and then the protruding part 23 on the top cover part 2 is used to press the sealing member 4 to seal the wire outlet groove 16. The sealing member 4 can be a sealing sponge. When using the sealing sponge, the sealing sponge is wrapped around the cable to position the cable and ensure the sealing performance. The setting of the wire arranging elastic buckle 17 is to increase the neatness inside the box body, avoid the cables being in a mess and damaging the cables; a neat cable layout can not only protect the cables more effectively but also facilitate later maintenance. In some embodiments, a sealing ring (not shown in the figure) is also arranged around the opening of the installation cavity 11 to increase the sealing performance between the top cover part 2 and the base part 1. The material of the sealing ring can be a sponge or other rubber rings made of sealing materials, and the specific material is not limited herein.

[0057] As Figure 1 and Figure 6As shown, in an optional embodiment, at least one latch portion 18 is further provided at one end of the base portion 1, and a second fixing buckle hole 19 is provided at the other end of the base portion 1. The latch portion 18 and the second fixing buckle hole 19 are used to fix the electronic control box 100 to the panel bracket 200 of the air conditioner.

[0058] Specifically, at least one latch hole (not shown in the figure) is provided on the panel bracket 200 of the air conditioner. The latch portion 18 is provided at one end of the base portion 1, and the latch portion 18 of the base portion 1 is inserted into the latch hole to fix one end of the electronic control box 100. A second fixing buckle hole 19 is provided at the end of the base portion 1 away from the latch portion 18, and a second buckle (not shown in the figure) adapted to the second fixing buckle hole 19 is provided at a position on the panel bracket 200 of the air conditioner corresponding to the second fixing buckle hole 19. The other end of the electronic control box 100 is fixed by the second buckle and the second fixing buckle hole 19.

[0059] During the installation of the present application, the electronic control box is first assembled to the panel bracket 200. One end of the base portion 1 is inserted into the latch hole opened on the panel bracket 200 through the latch portion 18, and then the other end of the base portion 1 is fixed through the buckle structure. After the base portion of the electronic control box is preliminarily fixed, the cover portion 2 of the electronic control box is in an open state. At this time, the cable plug is inserted into the socket on the circuit board, the cable is fixed by the cable management buckle 17, and the cable is passed through the wire outlet groove 16 and wrapped with sealing sponge. Then the top cover portion is closed. After closing, the convex portion on the top cover portion presses the sealing sponge on the cable, compressing the sealing sponge, thereby playing a role in sealing the wire outlet groove. In some optional embodiments, a convex portion (not shown in the figure) may also be provided in the wire outlet groove 16. The convex portion is disposed opposite to the convex portion 23. The sealing sponge is pressed tightly by both the convex portion and the convex portion 23, and the sealing effect is better.

[0060] Please refer to Figures 8 - 11 As shown, the present application also relates to an air conditioner, and the air conditioner includes the above-mentioned electronic control box 100. The electronic control box 100 of the present application has an integral rotating structure. The electronic control box 100 only requires one mold, which reduces the mold cost and simplifies the material management; at the same time, it is also convenient for installation and disassembly, facilitating subsequent maintenance work.

[0061] In this embodiment, the air conditioner further includes a panel bracket 200, and the electronic control box 100 is detachably installed on the panel bracket 200. For the specific structure of the electronic control box 100, please refer to the above-mentioned embodiment and will not be elaborated here.

[0062] The above are only exemplary embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
