Description

Technical Field

[0001] This utility model relates to the field of heat pump equipment technology, and in particular to an electrical control box and an integrated heat pump unit. Background Technology

[0002] Existing integrated heat pump units, also known as heat pump air conditioner outdoor units, integrate a water circulation system on the basis of traditional air conditioner outdoor units to achieve heating and hot water supply in winter.

[0003] In the electrical control section, existing integrated heat pump units generally employ dual control boards, adding an auxiliary control board to the traditional main air conditioner control board to control the water circulation system. The main and auxiliary control boards are mounted together via a control board bracket, with the main board on the front and the auxiliary control board on the back. When after-sales maintenance requires repairing the auxiliary control board on the back, adjacent components (such as the top cover and sound insulation panels) are typically disassembled first, followed by removing the control board bracket before repairing the auxiliary control board. After repair, the bracket and adjacent components must be reinstalled one by one. This cumbersome process leads to low efficiency and negatively impacts the user's after-sales service experience. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the prior art and provide an electrical control box for an integrated heat pump unit, which can improve the efficiency of after-sales maintenance and thus enhance the user's after-sales service experience.

[0005] This utility model is achieved through the following technical solution: an electrical control box for an integrated heat pump machine, comprising a drive board bracket, a drive board, a control board bracket, a first control board, a second control board, and a locking assembly; the drive board is disposed on the drive board bracket, the first control board is disposed on the front of the control board bracket, the second control board is disposed on the back of the control board bracket, the control board bracket is rotatably connected to the drive board bracket, and its relative position to the drive board bracket can be locked by the locking assembly, and the drive board and the second control board are respectively electrically connected to the first control board.

[0006] Compared with existing technologies, the electrical control box provided by this utility model independently mounts the high-heat-generating drive board via a drive board bracket, and mounts the first and second control boards via a control board bracket. This makes the layout of the electrical control components of the integrated heat pump unit more reasonable, avoiding space occupation and complex wiring. Furthermore, the control board bracket and the drive board bracket are rotatably connected, and the relative positions of the control board bracket and the drive board bracket can be locked by a locking component. During after-sales maintenance, only the locking component needs to be unlocked and the control board bracket rotated to inspect the second control board on the back of the control board bracket without disassembling the control board bracket. This simplifies the after-sales maintenance process, improves after-sales maintenance efficiency, and enhances the user's after-sales service experience.

[0007] Furthermore, the drive board bracket includes a main bracket, and a first connector and a second connector respectively disposed at the top and bottom of the main bracket. The first connector and the second connector are rotatably connected to the control board bracket. The first connector and the second connector ensure a certain gap between the control board bracket and the drive board bracket, which helps with heat dissipation.

[0008] Furthermore, the first connector is a Z-shaped connector, which includes a support portion disposed at the top of the main bracket and a connecting portion disposed at the end of the support portion. The connecting portion is rotatably connected to the control board bracket. The Z-shaped connector enables a non-planar connection between the drive board bracket and the control board bracket. Simultaneously, the Z-shaped connector avoids stress concentration and provides good structural stability.

[0009] Furthermore, the connecting part is provided with a first pin hole, and the top of the control board bracket is provided with a second pin hole; the electrical control box also includes a first pin, which passes through the first pin hole and the second pin hole and hinges the connecting part to the top of the control board bracket. The rotational connection between the control board bracket and the first connecting member is achieved through the cooperation of the first pin with the first pin hole and the second pin hole.

[0010] Furthermore, the first connecting member has a first limiting portion on the side near the front of the control board bracket to restrict the rotation of the control board bracket; the locking assembly includes a first locking assembly, which includes a first locking member and a second locking member. The first locking member is disposed on the first limiting portion, and the second locking member is disposed on the control board bracket. When the control board bracket rotates to abut against the first limiting portion, the first locking member and the second locking member cooperate to lock. The rotation direction of the control board bracket is restricted by the first limiting portion, and the first locking member and the second locking member are respectively provided on the first limiting portion and the control board bracket. The locking between the control board bracket and the drive board bracket is achieved through the cooperation of the first locking member and the second locking member.

[0011] Furthermore, the second connector is provided with a third pin hole, and the bottom of the control board bracket is provided with a fourth pin hole; the electrical control box also includes a second pin, which passes through the third pin hole and the fourth pin hole and hinges the second connector to the bottom of the control board bracket. The rotational connection between the control board bracket and the second connector is achieved through the cooperation of the second pin with the third pin hole and the fourth pin hole.

[0012] Furthermore, the second connector has a second limiting portion on the side near the back of the control board bracket to restrict the rotation of the control board bracket; the locking assembly also includes a second locking assembly, which includes a third locking member and a fourth locking member. The third locking member is disposed on the second limiting portion, and the fourth locking member is disposed on the control board bracket. When the control board bracket rotates to abut against the second limiting portion, the third locking member and the fourth locking member cooperate to lock. The rotation direction of the control board bracket is restricted by the second limiting portion, and the third locking member and the fourth locking member are respectively disposed on the second limiting portion and the control board bracket. Through the cooperation of the third locking member and the fourth locking member, the locking between the control board bracket and the drive board bracket is achieved.

[0013] Furthermore, the support portion is detachably connected to the main bracket, and the support portion is provided with a limiting groove for the main bracket to be inserted, the limiting groove extending along the length direction of the main bracket. The design of the limiting groove helps to position the first connector on the main bracket during installation, while preventing the first connector from becoming loose in the horizontal direction.

[0014] Furthermore, it also includes a mounting base for mounting the terminal block, the mounting base being disposed at the end of the second connector, the second connector being rotatably connected to the control board bracket via the mounting base. The mounting base for mounting the terminal block facilitates wiring and routing for the first and second control boards.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Example 1

[0027] like Figures 1 to 6 As shown, this embodiment provides an electrical control box for an integrated heat pump unit, including a drive board bracket 10, a drive board 20, a control board bracket 30, a first control board 50, a second control board 60, and a locking assembly 40. The drive board 20 is disposed on the drive board bracket 10, the first control board 50 is disposed on the front of the control board bracket 30, and the second control board 60 is disposed on the back of the control board bracket 30. The control board bracket 30 is rotatably connected to the drive board bracket 10, and its relative position to the drive board bracket 10 can be locked by the locking assembly 40. The drive board 20 and the second control board 60 are electrically connected to the first control board 50, respectively. The heat pump unit features a rational layout of its electrical control components by independently mounting the high-heat-generating drive board 20 on the drive board bracket 10, and mounting the first control board 50 and the second control board 60 on the control board bracket 30. This design avoids space occupation and complex wiring. The control board bracket 30 is rotatably connected to the drive board bracket 10, and the relative positions of the control board bracket 30 and the drive board bracket 10 can be locked by the locking component 40. During after-sales maintenance, simply unlocking the locking component 40 and rotating the control board bracket 30 allows for inspection of the second control board 60 on the back of the control board bracket 30 without disassembling the control board bracket 30. This simplifies the after-sales maintenance process, improves efficiency, and enhances the user's after-sales service experience.

[0028] In this embodiment, the drive board bracket 30 includes a main bracket 11, and a first connector 12 and a second connector 13 respectively disposed at the top and bottom of the main bracket 11. The first connector 12 and the second connector 13 are rotatably connected to the control board bracket 30. The first connector 12 and the second connector 13 ensure that there is a certain gap between the control board bracket 30 and the drive board bracket 10, which helps with heat dissipation.

[0029] In this embodiment, the main support 11 includes a mounting plate 111 and a fixing bracket 112 for fixing the drive plate 20. The mounting plate 111 has a mounting opening 113 for placing the fixing bracket 112, and the bottom of the mounting plate 111 has a folded edge 114 for limiting and supporting the fixing bracket 112. The front and rear sides of the mounting plate 111 are respectively provided with a first assembly part 119 and a second assembly part 120 for assembly with the chassis of the integrated heat pump unit. One side of the fixing bracket 112 has a boss 115 that matches the mounting opening 113. The boss 115 is engaged with the mounting opening 113 and protrudes from the mounting plate 111 through the mounting opening 113. The side of the fixing bracket 112 facing away from the boss 115 has a first mounting groove 116, the boss 115 has a second mounting groove 117, and the fixing bracket 112 has a heat dissipation vent 118 that connects the first mounting groove 116 and the second mounting groove 117. The second connector 13 is connected to the mounting plate 111, and the first connector 12 is connected to the mounting plate 111 and the fixing frame 112.

[0030] The drive board 20 includes a substrate 21, a heat sink 22, and several electronic components. The substrate 21 is disposed within the first mounting groove 116, and the heat sink 22 is disposed within the second mounting groove 117. Electronic components that generate significant heat are disposed on the side of the substrate 21 facing the heat sink 22 and contact the heat sink 22 through the heat dissipation port 118; the remaining electronic components are disposed on the side of the substrate 21 away from the heat sink 22. The control board bracket 30 is disposed on the side of the drive board bracket 10 away from the heat sink 22, and a third mounting part 33 for assembly with the chassis of the integrated heat pump unit is provided on the side of the control board bracket 30 away from the drive board bracket 10. In this embodiment, the substrate 21, mounting plate 111, and fixing bracket 112 are all rectangular structures. Of course, in other alternative embodiments, they can be circular, elliptical, or other polygonal shapes; irregular shapes can also be designed according to actual conditions, and there are no limitations on this.

[0031] In this embodiment, the first connector 12 is a Z-shaped connector, which includes a support portion 121 disposed on the top of the main bracket 11 and a connecting portion 122 disposed at the end of the support portion 121. The connecting portion 122 is rotatably connected to the top of the control board bracket 30. The Z-shaped connector 12 enables a non-planar connection between the drive board bracket 10 and the control board bracket 30. Furthermore, the Z-shaped connector avoids stress concentration and provides good structural stability. Of course, in other alternative embodiments, the first connector 12 is not limited to a Z-shaped structure; it only needs to enable a non-planar connection between the drive board bracket 10 and the control board bracket 30, and this is not a limitation.

[0032] In this embodiment, the connecting part 122 is provided with a first pin hole 1221, and the top of the control board bracket 30 is provided with a second pin hole 31. The electrical control box also includes a first pin 70, which passes through the first pin hole 1221 and the second pin hole 31 and hinges the connecting part 12 to the top of the control board bracket 30. The control board bracket 30 and the first connecting member 12 are rotatably connected by the first pin 70 engaging with the first pin hole 1221 and the second pin hole 31. Of course, in other alternative embodiments, the rotatable connection between the control board bracket 30 and the first connecting member 12 is not limited to the first pin 70 engaging with the first pin hole 1221 and the second pin hole 31; it can also be achieved by a rotating shaft engaging with a shaft hole, or by a hinge.

[0033] In this embodiment, the first connecting member 12 has a first limiting portion 1222 on the side near the front of the control board bracket 30 for restricting the rotation of the control board bracket 30; the locking assembly includes a first locking assembly 40, which includes a first locking member 401 and a second locking member 402. The first locking member 401 is disposed on the first limiting portion 1222, and the second locking member 402 is disposed on the control board bracket 30. When the control board bracket 30 rotates to abut against the first limiting portion 1222, the first locking member 401 and the second locking member 402 cooperate to lock. Specifically, the first connecting member 12 has a plate-like structure, and its side near the front of the control board bracket 30 is folded downward to form the first limiting portion 1222. The first locking member 401 is a screw disposed on the first limiting part 1222, and the second locking member 401 is a screw hole disposed on the control board bracket 30. When the control board bracket 30 rotates to abut against the first limiting part 1222, the control board bracket 30 and the drive board bracket 10 are locked through the cooperation of the screw and the screw hole. Thus, the rotation direction of the control board bracket 30 is restricted by the first limiting part 1222, and the screw and screw hole are respectively provided on the first limiting part 1222 and the control board bracket 30, and the locking between the control board bracket 30 and the drive board bracket 10 is achieved through the cooperation of the screw and the screw hole. Of course, in other alternative embodiments, the first locking member 401 and the second locking member 402 are not limited to locking by screws and screw holes. The locking between the control board bracket 30 and the drive board bracket 10 can also be achieved by the magnetic attraction of the first magnetic member and the second magnetic member, or by the snap-fit ​​of the first snap-fit ​​and the second snap-fit.

[0034] In this embodiment, the end of the second connector 13 is provided with a third pin hole 131, and the bottom of the control board bracket 30 is provided with a fourth pin hole 32. The electrical control box also includes a second pin 80, which passes through the third pin hole 131 and the fourth pin hole 32 and hinges the second connector 13 to the bottom of the control board bracket 30. The control board bracket 30 and the second connector 13 are rotatably connected by the second pin 80 engaging with the third pin hole 131 and the fourth pin hole 32. Of course, in other alternative embodiments, the rotatable connection between the control board bracket 30 and the second connector 13 is not limited to the second pin 80 engaging with the third pin hole 131 and the fourth pin hole 32; it can also be achieved by a rotating shaft engaging with a shaft hole, or by a hinge.

[0035] In this embodiment, the second connecting member 13 has a second limiting portion 132 on the side near the back of the control board bracket 30 to restrict the rotation of the control board bracket 30; the locking assembly further includes a second locking assembly 41, which includes a third locking member 411 and a fourth locking member 412. The third locking member 411 is disposed on the second limiting portion 132, and the fourth locking member 412 is disposed on the control board bracket 30. When the control board bracket 30 rotates to abut against the second limiting portion 132, the third locking member 411 and the fourth locking member 412 cooperate to lock. Specifically, the second connecting member 13 has a plate-like structure, and the side near the back of the control board bracket 30 is folded upward to form the second limiting portion 132. The third locking element 411 is a screw disposed on the second limiting part 132, and the fourth locking element 412 is a screw hole disposed on the control board bracket 30. When the control board bracket 30 rotates to abut against the second limiting part 132, the control board bracket 30 and the drive board bracket 10 are locked through the cooperation of the screw and the screw hole. Thus, the rotation direction of the control board bracket 30 is restricted by the second limiting part 132, and the screw and screw hole are respectively disposed on the second limiting part 132 and the control board bracket 30, and the locking between the control board bracket 30 and the drive board bracket 10 is achieved through the cooperation of the screw and the screw hole. Of course, in other alternative embodiments, the third locking element 411 and the fourth locking element 412 are not limited to the form of screw and screw to achieve locking. The locking between the control board bracket 30 and the drive board bracket 10 can also be achieved through the magnetic attraction of the third magnetic element and the fourth magnetic element, or the snap-fit ​​of the third snap-fit ​​and the fourth snap-fit.

[0036] In this embodiment, the support portion 121 is detachably connected to the main bracket 11. The support portion 121 is provided with a limiting groove 1211 for the main bracket 11 to be inserted into, and the limiting groove 1211 extends along the length direction of the main bracket 11. Specifically, the support portion 121 is provided with a first folded edge 1212, a second folded edge 1213, and a third folded edge 1214. The first folded edge 1212 is located at the end of the support portion 121 away from the connecting portion 122. The second folded edge 1213 and the third folded edge 1214 are both parallel to the first folded edge 1212 and are located on both sides of the end of the support portion 121 away from the connecting portion 122. The second folded edge 1213 and the third folded edge 1214 are on the same plane. The first folded edge 1212, the second folded edge 1213, and the third folded edge 1214 define the limiting groove 1211. After assembly, the mounting plate 111 and fixing bracket 112 of the main support 11 are inserted into the limiting groove 1211. The second folded edge 1213 and the third folded edge 1214 respectively abut against the side of the fixing bracket 112 away from the mounting plate 111, and the first folded edge 1212 abuts against the side of the mounting plate 111 away from the fixing bracket 112. The design of the limiting groove 1211 helps to position the first connector 12 on the main support 11 and avoids loosening of the first connector 12 in the horizontal direction. Of course, in other alternative embodiments, the first connector 12 can be designed as an integral part of the main support 11. In this embodiment, the support part 121 is connected to the main support 11 by screws. Of course, in other alternative embodiments, it can also be fixed to the main support 11 by welding, bonding, or other methods.

[0037] In some optional embodiments, the electrical control box further includes a mounting base 90 for mounting a terminal block. The terminal block is used for wiring and routing of the first control board 50 and the second control board 60, such as connecting to an external power supply. The mounting base 90 has an L-shaped structure, is connected to the second connector 13, and is located below the control board bracket 30. The second connector 13 is rotatably connected to the control board bracket 30 via the mounting base 90. The mounting base 90 and the second connector 13 are separate designs and can be connected by welding, screws, or clips. Of course, in other optional embodiments, the second connector 13 and the mounting base 90 can be an integrated design.

[0038] Compared with existing technologies, the electrical control box provided by this utility model independently mounts the high-heat-generating drive board via a drive board bracket, and mounts the first and second control boards via a control board bracket. This makes the layout of the electrical control components of the integrated heat pump unit more reasonable, avoiding space occupation and complex wiring. Furthermore, the control board bracket and the drive board bracket are rotatably connected, and the relative positions of the control board bracket and the drive board bracket can be locked by a locking component. During after-sales maintenance, only the locking component needs to be unlocked and the control board bracket rotated to inspect the second control board on the back of the control board bracket without disassembling the control board bracket. This simplifies the after-sales maintenance process, improves after-sales maintenance efficiency, and enhances the user's after-sales service experience.
