[0002] With technological advancements, smart home systems are becoming increasingly commonplace in our daily lives. The central control box is a crucial component of these systems, particularly in four-inch central control systems. In a conventional central control system, the base box is typically connected to the mounting box (also known as the 86-inch box) via screws, and then the panel switches are installed.

[0003] However, in a four-inch central control structure, the display screen and the electronic components in the mounting box are connected by a flexible printed circuit board. During installation, if conventional installation methods are used, the display screen and mounting box must be separated first, and then the separate mounting box must be connected to the base box with screws. Finally, the display screen and mounting box must be installed. This will cause damage to the display screen and the flexible printed circuit board in the mounting box, especially the motherboard flexible cable, and will also make it difficult to install the junction box assembly.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figures 1 to 3 As shown, an embodiment of the present invention provides a junction box assembly, which includes: a base box 10 and a mounting box 20. The base box 10 is provided with a protective groove 11, and a first clamping portion 12 is provided on the side wall of the protective groove 11; the mounting box 20 includes a box body 21 and an end plate 22 connected to each other, at least a portion of the box body 21 is installed in the protective groove 11, and a second clamping portion 23 is provided on the side wall of the box body 21. The second clamping portion 23 has a clamping position for clamping with the first clamping portion 12 and a disengagement position for disengaging from the second clamping portion 23; the end plate 22 is provided around the periphery of the box body 21 and abuts against the notch of the protective groove 11. The end plate 22 is provided with an avoidance operation hole 221, which is arranged opposite to at least a portion of the second clamping portion 23.

[0032] By using the junction box group provided in this embodiment, during the process of installing the installation box 20 on the base box 10, it is only necessary to press the installation box 20 onto the base box 10 to realize the mutual engagement of the first clamping portion 12 and the second clamping portion 23, thereby fixing the installation box 20 on the base box 10; during the installation process, there is no need to install the installation box 20 separately, nor is there any need to separate the installation box 20 with the display screen 40 from the display screen 40 to expose the threaded holes and connect them by screw connection, which facilitates installation. Furthermore, during disassembly, since the end plate 22 is provided with a relief operation hole 221 disposed opposite to the second clamping portion 23, it is necessary to first disassemble the switch panel or the display screen 40 connected to the display screen 40. Since disassembly often means damage to the junction box assembly, even if the installation box 20 with the display screen 40 is disassembled and separated from the display screen 40 and the circuit is damaged, it is within the permissible range of operation. Subsequently, an operating tool is inserted into the relief operation hole 221 to press the second clamping portion 23 with the operating tool to place the second clamping portion 23 in the separation position, and then the installation box 20 is pulled out of the base box 10, thereby completing the disassembly of the installation box 20. Therefore, the junction box assembly provided by this embodiment can simplify the installation and disassembly operations of the installation box 20, improve the installation and disassembly efficiency of the junction box assembly, and reduce the probability of product damage during the installation and disassembly process.

[0033] Specifically, the junction box group can be a central control structure with a display screen 40, and the display screen 40 can also be understood as an operating screen. Specifically, the junction box group can be four inches.

[0034] In this embodiment, there are multiple first clamping parts 12, which are spaced apart along the periphery of the side wall of the protective groove 11. There are multiple second clamping parts 23, which are arranged in a one-to-one correspondence with the multiple first clamping parts 12, and each second clamping part 23 is used to engage with the corresponding first clamping part 12. There are multiple avoidance operation holes 221, which are spaced apart around the periphery of the end plate 22, and the multiple avoidance operation holes 221 are arranged in a one-to-one correspondence with the multiple second clamping parts 23, and each avoidance operation hole 221 is arranged opposite to the corresponding second clamping part 23. This structural arrangement not only makes the engagement more stable and improves the stability of the clamping fixation between the installation box 20 and the base box 10, but also prevents the installation box 20 from falling off during use, thereby damaging the junction box assembly and reducing the damage rate.

[0035] Specifically, the first engaging portion 12 is a engaging protrusion, and the second engaging portion 23 is a hook. The hook is adjustable so as to be movable to an engaged position or a disengaged position. This structural arrangement is simple and not only facilitates adjustment of the engaging position of the mounting box 20, improving the flexibility of the engaging connection, but also facilitates pressing the second engaging portion 23 during disassembly, simplifying the disassembly process.

[0036] Specifically, one end of the hook is connected to the side wall of the box body 21. When the hook is in the engaged position, the other end of the hook is spaced apart from the side wall of the box body 21 to form a deformation space for the other end of the hook to deform. This structural arrangement provides sufficient deformation space when the second engaging portion 23 is pressed, facilitating the removal of the mounting box 20 and reducing the risk of damage to the mounting box 20 during the removal process.

[0037] Specifically, the hook can undergo a certain elastic deformation, and the hook can be made of a material with a certain elastic deformation, such as a plastic material or a metal material.

[0038] In this embodiment, the bottom box 10 is installed in the installation groove 31 of the installation base 30, and the end plate 22 abuts against the end wall 32 of the notch surrounding the installation groove 31. With such a structural setting, it is easy to position the installation box 20 and facilitate the installation and removal of the installation box 20. Specifically, when the end plate 22 abuts against the end wall 32 at the notch of the installation groove 31, the installation box 20 can be installed in place; when it needs to be removed, it is only necessary to use an operating tool to pry open the end plate 22 near the end wall 32 of the notch of the installation groove 31. In addition, the above-mentioned setting can also facilitate the installation of the bottom box 10 and prevent the bottom box 10 from being damaged. The bottom box 10 embedded in the wall can also improve the aesthetics of the four-inch central control structure. Specifically, the operating tool can be an operating lever or an operating screwdriver.

[0039] Specifically, the mounting groove 31 is adapted to the size of the bottom box 10 so that the bottom box 10 can be installed in the mounting groove 31. Specifically, the mounting base 30 can be a wall, and the mounting groove 31 is reserved on the wall, and the bottom box 10 is pre-buried in the mounting groove 31. Preferably, the mounting groove 31 and the bottom box 10 have an interference fit.

[0040] like Figure 4 As shown, the junction box assembly also includes a display screen 40, which is provided with a positioning groove 41 that matches the shape of the end plate 22. The end plate 22 is installed in the positioning groove 41. This structural arrangement ensures a stable connection between the display screen 40 and the end plate 22, preventing the display screen 40 from moving during use, which could damage the junction box assembly, particularly the connection between the display screen 40 and the installation box 20. Specifically, the installation box 20 is installed with a connecting line for connecting to the display screen 40. This connecting line can be a motherboard flexible cable.

[0041] Specifically, a third clamping portion 222 is provided on the end plate 22, and a fourth clamping portion 42 that is compatible with the third clamping portion 222 is provided in the positioning groove 41. With such a structural setting, the display screen 40 can be clamped and fixed to the end plate 22 without using screws for fixing, which facilitates the disassembly of the display screen 40. Specifically, generally, when the device is shipped from the factory, the installation box 20 and the display screen 40 are already installed, that is, the installation box 20 has been wired to the display screen 40. When the entire junction box assembly is damaged and needs to be replaced, it is only necessary to use an operating tool to lift the display screen 40 to separate the installation box 20 from the display screen 40, which facilitates disassembly. In addition, it also reduces the risk of threaded connections causing damage to the display screen 40 or affecting the overall aesthetics of the junction box assembly.

[0042] Specifically, the third clamping portion 222 may be a clamping protrusion, and the fourth clamping portion 42 may be a clamping groove.

[0043] Specifically, there are multiple third clamping portions 222, which are spaced apart along the circumference of the end plate 22. There are multiple fourth clamping portions 42, which are arranged in a one-to-one correspondence with the multiple third clamping portions 222, and each third clamping portion 222 is clamped with a corresponding fourth clamping portion 42. With this structural arrangement, the multiple clamping portions are mutually clamped, which can better ensure the connection stability between the display screen 40 and the installation box 20 under normal use, thereby improving the fixing stability of the display screen 40.

[0044] In this embodiment, the bottom box 10 is installed in the installation groove 31 of the installation base 30, and the display screen 40 abuts against the end wall 32 surrounding the notch of the installation groove 31. This structural arrangement can facilitate the abutment and positioning of the display screen 40, prevent the display screen 40 from moving, and improve the installation stability of the display screen 40.

[0045] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: facilitating the installation of the junction box assembly, improving the efficiency of installation and disassembly, and reducing the probability of damage to the display screen during the installation process.
