DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0046] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] At present, the layout of the electrical box and its internal electric control components is not designed properly, so a relatively large electrical box is needed to accommodate the electric control components. When assembling a large electrical box, the heat pump unit needs to reserve a larger space, which is not conducive to the miniaturization of the heat pump unit. At the same time, after the entire electrical box is installed in the box of the heat pump unit, only an openable inspection door is opened on the side of the box for later maintenance. However, the box has a certain space size inside, and the electric control components are generally installed in multiple layers. For the maintenance of the electric control components far from the inspection door, it is often difficult to repair or even impossible to repair. In addition, there are many electric control components inside the electrical box, which require a large number of electrical connection wires to connect. If the wiring of the electrical connection wires is not designed properly, pre-installation and disassembly maintenance are both troublesome. Therefore, it is of great significance to develop a heat pump unit electrical box with a reasonable internal distribution and easy installation and maintenance.

[0048] Based on this, the utility model provides an electrical box installation structure, which divides the accommodating cavity into two chambers by arranging a first installation plate in the accommodating cavity inside the electrical box, and independently arranges the driving component and the main control component in the two chambers, so that the internal space distribution of the electrical box is more reasonable and compact, which is conducive to the miniaturized design of the electrical box; at the same time, by arranging an inspection port and a corresponding openable and closable inspection plate at the first installation plate, later maintenance is facilitated, thereby improving the operating efficiency of the heat pump unit.

[0049] Please also see Figure 1 and Figure 2The utility model provides an electrical box installation structure, including a box body 10, a first mounting plate 20, an electric control component 30 and an inspection plate 40. A receiving cavity is provided inside the box body 10, and the receiving cavity includes a first chamber 11 and a second chamber 12. The first mounting plate 20 is fixed in the receiving cavity, and the first chamber 11 and the second chamber 12 are separated by the first mounting plate 20. An inspection port 20a is provided at one end of the first mounting plate 20, and the first chamber 11 and the second chamber 12 are connected through the inspection port 20a. The electric control component 30 includes a driving component 31 and a main control component 32, the driving component 31 is arranged in the first chamber 11, and the main control component 32 is arranged in the second chamber 12. The inspection plate 40 is covered on the inspection port 20a, and one end of the inspection plate 40 is connected to the first mounting plate 20 through a first connecting structure. Therefore, when the driving component 31 of the first chamber 11 needs maintenance, the inspection panel 40 can be opened, and the maintenance work can be carried out by entering the first chamber 11 from the second chamber 12 through the inspection port 20a.

[0050] See also Figure 3 The box body 10 is formed by a plurality of panels, a bottom plate and a top cover. In order to facilitate the assembly and wiring of the electric control component 30 in the early stage and the maintenance in the later stage, the top cover is detachably covered on the top of the accommodating cavity and covers the accommodating cavity. As an example, the box body 10 includes a plurality of panels 13 and a top cover 14. The panels 13 include a first panel 131, a second panel 132, a third panel 133 and a fourth panel 134. The first panel 131 and the second panel 132 are arranged opposite to each other, and the third panel 133 and the fourth panel 134 are arranged opposite to each other. The third panel 133 can be connected to at least one of the first panel 131 and the second panel 133 in an openable and closable manner for the installation and maintenance in the later stage of the main control component 30. One end of the top cover 14 is connected to the first panel 131 by a snap connection structure, and the other end is fixed to the second panel 132 by screws. The snap connection structure specifically includes a snap member 141 and a snap hole 131a. The snap member 141 is arranged on the side of the top cover 14 facing the inside of the box body 10. The snap member 141 is provided with a connecting portion and a snap-fitting portion. The connecting portion and the snap-fitting portion are integrally connected. The connecting portion is fixed to the top cover 14, and the snap-fitting portion is L-shaped. The snap hole 131a is provided near one end of the first panel 131 close to the top cover 14. In the installed state, the snap-fitting portion is snapped on the snap member 131a. A connecting member 142 is provided at one end of the top cover 14 connected to the second panel 132. The connecting member 142 is arranged on the side of the top cover 14 facing the inside of the box body 10. A through hole is provided on the connecting member 142. A matching through hole is also provided near one end of the second panel 132 close to the top cover 14. The connecting member 142 is fixedly connected to the second panel 132 by screws.

[0051] In other embodiments, the top cover 14 is detachably connected to three or four panels at the same time to improve the stability of the connection between the top cover 14 and the panel 13. The connection between the top cover 14 and the panel 13 can all be connected by a snap connection structure, or can all be fixed by screws.

[0052] It can be understood that before the entire electrical box is installed in the box of the heat pump unit, the top cover 14 and the third panel 133 are opened at the same time to facilitate the installation of the electronic control component 30. After the entire electrical box is installed in the box of the heat pump unit, when the electronic control component needs maintenance, the third panel 133 and the inspection panel 40 can be opened first for maintenance. In the case of greater difficulty in maintenance, the top cover 14 can be opened at the same time. Therefore, setting up three maintenance windows allows maintenance personnel to selectively open the third panel 133, the inspection panel 40 and the top cover 14 according to the actual difficulty of maintenance, so as to make maintenance more efficient and convenient.

[0053] The first mounting plate 20 can be fixed to the bottom plate of the box body 10, or fixed to the inner wall of the box body 10. In this embodiment, the first mounting plate 20 is fixed to the inner wall of the box body 10, and one end of the first mounting plate 20 close to the bottom plate of the box body 10 is set at a distance from the bottom plate of the box body 10, so that a gap is formed between the first mounting plate 20 and the bottom plate of the box body 10, which is used for routing the electric control components between the first chamber 11 and the second chamber 12. Specifically, a support member 21 is provided in the accommodating cavity, one end of the support member 21 is fixed to one of the inner walls of the box body 10, and the other end is fixed to one end of the first mounting plate 20 away from the inspection plate 40, so as to provide support force for the first mounting plate 20, wherein the inner wall fixed to the support member 21 can be an inner wall opposite to or perpendicular to the inner wall close to the inspection plate 40. As an example, the first mounting plate 20 is arranged in parallel with the fourth panel 134, and its length is less than that of the fourth panel 134, and the arrangement position is close to the first panel 131. Two driving components 31 are provided, and the two driving components 31 are arranged in the first chamber 11 at intervals, and one of the driving components 31 is opposite to the first mounting plate 20. Therefore, the inspection port 20a and the inspection panel 40 are close to the first panel 131, so as to be used for maintaining the driving component 31 opposite to the first mounting plate 20. Since the other driving component 31 is not blocked by the first mounting plate 20, when maintenance is required, it is only necessary to open the third panel 133 to perform maintenance operations. The driving component 31 support member 21 is arranged between the two driving components 31. Preferably, the support member 21 is a support rod to facilitate the wiring between the two driving components 31. One end of the support member 21 is fixedly connected to the fourth panel 134 or the second panel 132, and the other end is fixedly connected to the first mounting plate 20. It is understandable that when the length of the first mounting plate 20 is equal to the fourth panel 134 , the two driving components 31 will be blocked by the first mounting plate 20 . At this time, inspection openings 20a and corresponding inspection panels 40 can be set at both ends of the first mounting plate 20 .

[0054] Furthermore, an inspection opening 20a is formed between one end of the first mounting plate 20 away from the support member 21 and the inner wall of the box body 10, and one end of the inspection plate 40 is connected to the end of the first mounting plate 20 away from the support member 21 through a first connection structure. The first connection structure includes a plurality of hinges 41, and one end of the inspection plate 40 is rotatably connected to the first mounting plate 20 through the hinges 41. The two movable leaves of each hinge 41 are respectively arranged on the inspection plate 40 and the first mounting plate 20, and the inspection plate 40 is rotatably connected to the first mounting plate 20 through the hinges 41, thereby facilitating the opening and closing of the inspection plate 40, so that maintenance personnel can perform maintenance operations on the driving component 31 from the inspection opening 20a. In other embodiments, the first connection structure may also be other movable connection modes, for example, the access panel 40 and the first mounting plate 20 are provided with matching sliding connection structures, through which the access panel 40 can be easily slid open or cover the access opening 20a; for another example, the access panel 40 and the first mounting plate 20 are provided with matching snap connection structures, during normal operation, the access panel 40 is snap-connected to the first mounting plate 20 through the snap connection structure, and when maintenance is required, the access panel 40 can be easily opened or removed from the first mounting plate 20. One end face of the access panel 40 away from the first mounting plate 20 abuts against the inner wall of the box body 10, specifically, one end face of the access panel 40 away from the first mounting plate 20 abuts against the first panel 131. By providing the inspection plate 40 on the first mounting plate 20, on the one hand, it is convenient to open and close the inspection plate 40, so as to facilitate the maintenance of the driving component 31 arranged on the other side of the first mounting plate 20 in the later stage; on the other hand, when the heat pump unit is operating normally, the first mounting plate 20 is connected to the inner wall of the box body 10 through the inspection plate 40, which can improve the stability of the first mounting plate 20 and prevent the first mounting plate 20 from falling and causing damage to the main control component 32.

[0055] Furthermore, in order to increase the contact area between the inspection plate 40 and the inner wall of the box body 10, so as to further improve the stability of the connection between the inspection plate 40 and the box body 10, a flange 42 is provided at the end of the inspection plate 40 away from the first mounting plate 20, and one end of the flange 42 is connected to the inspection plate 40. Preferably, the flange 42 is arranged perpendicular to the inspection plate 40 so that the flange 42 is tightly attached to the first mounting plate 20 in the installed state.

[0056] In a further embodiment, an abutment piece (not shown) is provided on the surface where the inspection plate 40 abuts against the inner wall of the box body 10 to make the connection between the inspection plate 40 and the inner wall of the box body 10 tighter. The abutment piece is made of a soft rubber material. The abutment piece made of soft rubber can better abut against the inner wall of the box body 10, which is tighter than the direct sheet metal abutment between the inspection plate 40 and the box body 10.

[0057] Please also see Figures 4 to 6In another embodiment, one end of the first mounting plate 20 is fixedly connected to the inner wall of the box body 10, and the inspection port 20a is opened in the first mounting plate 20. Specifically, one end of the first mounting plate 20 is fixedly connected to the first panel 131, and the inspection port 20a is opened at one end of the first mounting plate 20 close to the first panel 131. A matching second connection structure is provided between one end of the inspection plate 40 away from the hinge 41 and the first mounting plate 20. The second connection structure includes a clamping member 43, a clamping slot 43a and a stopper 44. The clamping member 43 is arranged on the inspection plate 40. Preferably, the clamping member 43 is arranged on one end of the inspection plate 40 away from the hinge 41 and toward the side of the second chamber 12. The slot 43a is opened on the first mounting plate 20. The position of the slot 43a corresponds to the position of the clamping member 43, and it is provided with two interconnected slots, one of which faces the clamping member 43 and the other faces away from the first chamber 11, so that the clamping member 43 is clamped in the slot 43a. The limiting member 44 can be a plate-like structure, a block structure, a columnar structure or other structures. In the present embodiment, it is a baffle. One end of the limiting member 44 is rotatably connected to the first mounting plate 20 and is located in the vicinity of the slot 43a, and the other end is used to limit the clamping member 43 in the slot 43a. The specific installation process is: first rotate the limiter 44 to a position away from the slot 43a, then clamp the clamping member 43 in the slot 43a, and then rotate the limiter 44 to the position of the slot 43a, so that the clamping member 43 is restricted in the slot 43a to prevent the clamping member 43 from moving out of the slot 43a, and finally achieve a more stable connection between the access panel 40 and the first mounting plate 20. The number of the clamping members 43 is several, and the number of the corresponding slots 43a and the limiter 44 matches the number of the clamping members 43.

[0058] Please refer again Figure 1 and Figure 2 Since there are many electric control components 30 inside the box body 10, a large number of electric connecting wires are required to realize the connection between the components. In order to avoid the misconnection and misplugging of the electric connecting wires during installation and maintenance as much as possible, the second chamber 12 is provided with a first wire collecting member 15 and a second wire collecting member 16. The first wire collecting member 15 is arranged on a side of the first mounting plate 20 facing the second chamber 12, and the first wire collecting member 15 is provided with a first wire collecting groove 15a, and the notch of the first wire collecting groove 15a faces the direction away from the first chamber 11. Both ends of the second wire collecting component 16 are fixedly connected to the inner wall of the box body 10, and the second wire collecting component 16 is provided with a second wire collecting groove 16a, and the groove of the second wire collecting groove 16a faces the top cover 14. Thus, the electrical connection wire harnesses can be classified, and then the wire harnesses of the same type can be arranged in the same first wire collecting groove 15a or second wire collecting groove 16a. In this way, the wiring is more reasonable and standardized, and it is not easy to cause the misconnection and misplugging of the electrical connection wires, which is convenient for installation and later maintenance, and also avoids the electrical control failure caused by the interference between different types of electrical connection wires.

[0059] Furthermore, when installing the second wire collection component 16, if it is directly fixed to the inner wall of the box body 10, it is inevitable to drill holes, which is not conducive to the waterproof design of the box body 10. Therefore, a second mounting plate 17 is provided on the inner wall of the box body 10, and the second mounting plate 17 is pre-fixed on the inner wall of the box body 10. The second wire collection component 16 is fixedly connected to the inner wall of the box body through the second mounting plate 17.

On the other hand, it can improve the stability of the first mounting plate.

[0064] (3) One end of the first mounting plate is fixedly connected to one of the inner walls of the box body through a support member, and the other end is directly fixedly connected to the other inner wall of the electrical box, so that the first mounting plate is stably installed, and the main control component is conveniently installed on the first mounting plate;

[0065] At the same time, the first mounting plate is spaced apart from the bottom plate of the box body, which facilitates the wiring between the first chamber and the second chamber;
