[0024] The specific implementation of the present utility model is described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 and Figure 2The utility model provides a hybrid integrated device of an inverter, a battery pack and a control system, including an energy storage component 3 and an inverter main component 5. The energy storage component 3 integrates the 485 interface of the BMS and the battery pack controlled by the CAN interface. The inverter main component 5 is connected to the control system through a wireless communication module. It includes a casing 1. The inner wall of the casing 1 is fixedly connected with four columns 2. The energy storage component 3 is fixedly installed on the four columns 2 by bolts. A lifting wall bracket 4 is provided on the top of the casing 1. The side wall of the lifting wall bracket 4 is fixedly connected with a top casing 6. The inverter main component 5 is arranged inside the top casing 6 and fixedly installed through the lifting wall bracket 4. The energy storage component 3 and the inverter main component 5 are provided with interconnected wiring channels on the back. The casing 1 is located in the wiring channel and is fixedly connected to a whole line rack 8. The top of the whole line rack 8 extends to the inside of the top casing 6 and is fixedly connected to the inner wall of the top casing 6. The whole line rack 8 is used to fix the power line and control the lifting of the lifting wall bracket 4. A back plate 7 is installed on the back of the casing 1 and the top casing 6.

[0026] By setting the casing 1, the lifting wall bracket 4 and the top shell 6, the energy storage component 3 and the inverter main component 5 can be integrated and installed, which is convenient for unified management. In addition, a wiring channel is set. By removing the back panel 7, it is convenient to sort the lines in the wiring channel, and the column 2 and the inverter main component 5 connection lines can be regularly fixed through the whole line rack 8 to avoid line confusion and difficulty in maintenance, and improve the aesthetics of the wiring. In addition, the lifting wall bracket 4 is set to be lifting. When wiring the inverter main component 5, the lifting wall bracket 4 can be driven by the whole line rack 8 to lift the inverter main component 5, so that the inverter main component 5 is raised, and a hollow wiring window is formed between the inverter main component 5 and the casing 1, so that the inverter main component 5 is more convenient during wiring operations. After the lifting wall bracket 4 is reset by the whole line rack 8, the wiring ports and corresponding lines of the inverter main component 5 are hidden in the casing 1 and the top shell 6, thereby improving the overall aesthetics of the equipment.

[0027] Reference Figure 3 The tops of the four columns 2 are each provided with a vertical slide groove 1, and the bottom ends of the four columns 2 pass through the casing 1 for support on the ground. The lifting wall frame 4 includes four side columns 41 and a main frame plate 44. The bottom ends of the four side columns 41 are respectively slidably sleeved in the vertical slide groove 1 of the four columns 2. Both ends of the main frame plate 44 are connected to side plates 42, and the two ends of the two side plates 42 are respectively fixedly connected to the side walls of the four side columns 41. The main frame plate 44 is used to fix the inverter main component 5.

[0028] Through the structural setting of the lifting wall rack 4, the four side columns 41 are slid along the vertical slide grooves of the four columns 2 to achieve the lifting effect of the lifting wall rack 4, thereby controlling the lifting of the inverter main component 5. In addition, after the lifting wall rack 4 is lowered, the bottom end of the side column 41 is supported at the bottom of the vertical slide groove of the column 2, so that the lifting wall rack 4 bears the weight of the inverter main component 5 and transfers it to the column 2, and the column 2 transfers the weight to the ground, thereby greatly reducing the weight of the casing 1 and the top shell 6 to avoid deformation of the casing 1 and the top shell 6.

[0029] Reference Figure 3 Both ends of the main frame plate 44 are fixedly connected with a tube sleeve plate 43, and the two tube sleeve plates 43 are slidably sleeved on the side walls of the two side plates 42. A threaded hole is opened on the top of the tube sleeve plate 43, and a positioning screw 45 is threadedly connected to the threaded hole.

[0030] By sliding the sleeve plate 43 on the side plate 42, the position of the main frame plate 44 can be adjusted, so that the lifting wall bracket 4 can be adjusted in position according to the size of the inverter main component 5, ensuring that the lifting wall bracket 4 can be connected to the inverter main component 5.

[0031] Reference Figure 4 The whole line frame 8 includes a vertical frame 81, the bottom end of the vertical frame 81 passes through the casing 1 and is supported on the ground. A vertical slide groove 2 is provided at the top of the vertical frame 81, and a mobile frame 83 is slidably sleeved in the second vertical slide groove. A threaded column hole is provided at the bottom end of the second vertical slide groove. The top of the mobile frame 83 is fixedly connected to a crossbeam 84, and both ends of the crossbeam 84 are connected to the lifting wall frame 4. An axial hole is provided at the top of the mobile frame 83, and the axial hole passes through the bottom end of the mobile frame 83. A rotary rod 85 is rotatably sleeved in the axial hole, and a threaded rod 86 is fixedly connected to the bottom end of the rotary rod 85. The threaded rod 86 is threadedly sleeved in the threaded column hole. A number of whole line arms 82 are fixedly connected on both sides of the vertical frame 81, and a number of wire grooves a are provided on the outer walls of the whole line arms 82.

[0032] By rotating the rotary rod 85, the threaded rod 86 is driven to rotate, and the threaded rod 86 is longitudinally displaced under the influence of the threaded structure, thereby driving the movable frame 83 to slide in the second vertical slide groove. Since the crossbeam 84 is connected to the lifting wall rack 4, the lifting effect of the lifting wall rack 4 is controlled. The energy storage component 3 and the inverter main component 5 lines are routed in the wiring channel. By clamping the lines into the wire groove a of the whole line arm 82, the lines are regularized and fixed.

[0033] Reference Figure 4 The diameter of the threaded rod 86 is larger than the diameter of the shaft hole of the movable frame 83 and the crossbeam 84.

[0034] Due to the diameter difference between the threaded rod 86 and the shaft hole, the threaded rod 86 can support the movable frame 83 when it moves upward, thereby sharing the load-bearing of the rotating rod 85 on the movable frame 83 and preventing the rotating rod 85 from falling out of the shaft hole.

[0035] Reference Figure 2 、 5 Both sides of the casing 1 are provided with heat dissipation slots that penetrate into the interior, and ventilation boxes 9 are fixedly connected to the heat dissipation slots. The internal channel of the ventilation box 9 is set to be V-shaped, and the ventilation box 9 is fixedly connected to a rain shield 91 at the channel opening at one end outside the casing 1.

[0036] By setting the heat dissipation slot, the interior of the casing 1 can be cooled. When the equipment is installed outdoors, rainwater can easily enter the interior of the casing 1 through the heat dissipation slot. Therefore, the channel of the ventilation box 9 is set to be V-shaped. When rainwater enters the internal channel of the ventilation box 9, the rainwater accumulates in the V-shaped channel under the influence of gravity, thereby achieving a certain waterproof effect and improving the safety performance of the equipment. In addition, by setting the rain shield 91, a certain water-blocking effect can be achieved, reducing the amount of rainwater entering the internal channel of the ventilation box 9.

[0037] Reference Figure 5 , the top b surface of the internal channel of the ventilation box 9 is provided with double-sided adhesive.

[0038] When heat is dissipated through the heat dissipation slots, the external airflow can easily carry dust into the interior of the casing 1 and affect the electrical components. In order to avoid this situation, double-sided adhesive is set. When the airflow enters the internal channel of the ventilation box 9, since the channel is V-shaped, the airflow will first collide with the b-side of the inner wall of the channel. At this time, the double-sided adhesive has an adhesion effect on the dust, and the airflow flows normally along the V-shaped channel, thereby separating the dust in the airflow and making the ventilation box 9 achieve a dust-proof effect.

[0039] Reference Figure 6 A drainage main pipe 93 is provided on one side of several ventilation boxes 9, and a drainage port connected to the internal channel is opened at the bottom of several ventilation boxes 9. The side wall of the drainage main pipe 93 is connected to several drainage branch pipes 92, and the other ends of several drainage branch pipes 92 are respectively connected to the drainage ports at the bottom of several ventilation boxes 9.

[0040] When water accumulates in the internal passage of the ventilation box 9 , the water may flow into the drainage main pipe 93 through the drainage branch pipe 92 and be discharged through the drainage main pipe 93 .
