[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0025] The terms "including" and "having" in the description and claims of the present application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0026] One of the preferred embodiments of the present application is as Figures 1 to 7 shown. An inverter junction box includes a box body 1 and a cooling box 2 installed on the side of the box body 1; a driving component 11 is provided on the side of the cooling box 2, and the driving component 11 and the box body 1 are matched through a locking structure 12; when installing the cooling box 2 for heat dissipation and cooling, the cooling box 2 can be slidably connected to the bottom of the box body 1, and then the driving component 11 is operated to move the cooling box 2 upward to abut and fit against the bottom of the box body 1, so as to dissipate heat from the box body 1 through the cooling box 2. When the cooling box 2 abuts against the box body 1, at this time, the cooling box 2 is firmly fixed to the bottom of the box body 1 through the locking structure 12, which is convenient for better heat dissipation and cooling, improves the heat dissipation effect, and is also convenient for the installation and disassembly of the cooling box 2, with strong practicability.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 4 shown, it can be understood that the cooling box 2 includes a mounting box 21 and two cooling elements 22; the mounting box 21 is slidably arranged at the bottom of the box body 1 in a manner of sliders and chutes, the two cooling elements 22 are slidably mounted on both sides of the mounting box 21, and the bottoms of the mounting box 21 and the two cooling elements 22 are flush with the bottom of the box body 1, so that after the cooling box 2 is installed, the overall structure can have a more stable support, which is convenient for better handling and installation.

[0028] In this embodiment, as Figure 2 , Figure 4 and Figure 7 shown, the driving assembly 11 includes an inclined block 111, a screw 112 and two connecting rods 113; the inclined block 111 is slidably mounted in the mounting box 21, the screw 112 is threadedly connected to the side of the mounting box 21 and one end of the screw 112 extends into the mounting box 21 and is rotatably connected to the side of the inclined block 111, the two cooling elements 22 are mounted on the sides of the corresponding connecting rods 113, and the two connecting rods 113 extend into the mounting box 21 and cooperate with the inclined block 111; when driving the cooling element 22 to fit against the bottom of the box body 1 for heat dissipation and cooling, the screw 112 can be rotated at this time, the rotation of the screw 112 can push the inclined block 111 to slide in the mounting box 21, the movement of the inclined block 111 can drive the two connecting rods 113 to move upward, and the upward movement of the connecting rods 113 can drive the cooling element 22 connected thereto to move upward to fit against the bottom of the box body 1. At this time, the bottom of the cooling element 22 is above the bottom of the box body 1, which is convenient for better heat dissipation, and the bottom of the mounting box 21 is still flush with the bottom of the box body 1, which is convenient for better supporting the whole.

[0029] In this embodiment, as Figures 4 to 7 shown, it can be understood that in order to better move and lock the cooling element 22, a spring is sleeved on the side of the connecting rod 113, and the two ends of the spring are respectively mounted on the outer wall of the connecting rod 113 and the side of the mounting box 21.

[0030] In this embodiment, as Figures 2 to 5As shown, the locking structure 12 includes a locking groove 122 formed on the side of the box body 1 and a locking block 121 installed on the side of the connecting rod 113. The side of the locking block 121 is inclined, and the side of the locking groove 122 is inclined. The locking block 121 and the locking groove 122 cooperate with each other. When locking the cooling member 22, the screw 112 rotates to push the inclined block 111 to slide. The sliding of the inclined block 111 drives the connecting rod 113 to move upward. The upward movement of the connecting rod 113 can elastically drive the locking block 121 to move upward until the locking block 121 elastically returns to extend into the locking groove 122, thereby locking and fixing the cooling member 22. When unlocking for replacing or repairing the cooling member 22, the screw 112 can be rotated in the reverse direction at this time. The screw 112 will pull the inclined block 111 to move. The movement of the inclined block 111 can cause the connecting rod 113 to move downward. When the connecting rod 113 moves downward, at this time, the inclined surface of the locking block 121 is squeezed against the inclined surface of the locking groove 122, so that the locking block 121 is elastically extruded out of the locking groove 122, thereby unlocking the cooling member 22, facilitating better replacement or repair of the cooling member 22, and improving the convenience and practicality of the device.

[0031] In this embodiment, as Figures 2 to 7 shown, it should be known that in order to make the locking block 121 better elastically extrude and extend from the locking groove 122, two inclined sliding grooves are formed on the side of the inclined block 111. The inclined sliding grooves are divided into a first vertical section, a second vertical section, and an inclined section. The two ends of the inclined section are connected to the first vertical section and the second vertical section in a penetrating manner. The sides of the two connecting rods 113 cooperate with the inclined sliding grooves. The first vertical section and the inclined section are formed on the inclined surface of the inclined block 111, and the second vertical section is formed on the horizontal surface of the inclined block 111. Therefore, when locking the cooling member 22, one end of the connecting rod 113 starts to slide from the first vertical section to the inclined section, and then slides from the inclined section to the second vertical section. At this time, the connecting rod 113 moves upward on the first vertical section. When sliding on the inclined section, it drives the compressed locking block 121 to extend into the locking groove 122, and finally stops at the second vertical section. When unlocking, the connecting rod 113 starts to slide from the second vertical section to the inclined section, and finally slides to the first vertical section. At this time, the connecting rod 113 moves downward on the second vertical section. On the inclined section, the locking block 121 squeezes the inclined surface of the locking groove 122 to extend out of the locking groove 122, and finally slides to the first vertical section to drive the cooling member 22 to move downward to be flush with the bottom of the box body 1.

[0032] In this embodiment, as Figure 2 and Figure 7As shown, it can be understood that in order to better limit the connecting rod 113 and facilitate the up and down movement of the connecting rod 113, a stop block 3 is provided on the side of the connecting rod 113. The stop block 3 is arranged inside the installation box 21. Thus, when the connecting rod 113 elastically drives the locking block 121 to extend, it can extend more stably, preventing the connecting rod 113 from protruding from the inclined surface of the inclined block 111, and improving the practicability and safety of the device.

[0033] In this embodiment, as Figure 2 shown, it should be known that the cooling member 22 includes a plurality of heat dissipation fins. The plurality of heat dissipation fins are arranged at equal intervals on the side of the connecting rod 113. Thus, by fitting the heat dissipation fins with the bottom of the box body 1, it is convenient to better dissipate heat from the box body 1.

[0034] It should be known that, as Figure 1 shown, a plurality of heat dissipation fins are also arranged at equal intervals on the side of the box body 1, which is convenient to better dissipate heat from the junction box through the heat dissipation fins.

Those skilled in the art should understand that the present application is not limited by the above embodiments.
