Description

Technical Field

[0001] This application relates to the technical field of inverters, and particularly to an easily formable and highly sealed inverter box body. Background Art

[0002] Currently, the inverter box body is an important part of the inverter, which is used to accommodate and protect the internal components of the inverter to ensure its normal operation. The inverter box body is applied to various scenarios, such as new energy vehicles, home energy storage systems, industrial equipment, etc., providing necessary physical protection and environmental isolation for the inverter.

[0003] However, the existing easily formable and highly sealed inverter box body has the following defects: for example, the box cover is usually connected to the outer shell by multiple bolts, and a gasket is provided between the box cover and the outer shell. However, due to the large force at the position where the bolts are located, the force at other positions is relatively small, resulting in uneven force on the box cover and generating gaps between the box cover and the gasket, thereby affecting the sealing performance of the entire box body and even causing faults or damages to the inverter inside the box body. Summary of the Invention

[0004] The purpose of this application is to improve the sealing performance of the inverter box body and reduce the faults or damages of the inverter on the inner wall of the box body.

[0005] To achieve the above purpose, the technical solution adopted in this application is: an easily formable and highly sealed inverter box body, including an outer shell. A bracket is fixedly connected to the outer wall at the rear end of the outer shell. A moving groove is provided on the outer wall of the bracket, and the number of moving grooves is multiple. A screw rod is movably connected to the outer wall at the rear end of the outer shell. A moving plate is threadedly connected to the outer wall of the screw rod. The moving plate includes multiple end parts. Each of the end parts respectively penetrates through one end of the multiple moving grooves and is fixedly connected to a connecting plate. The other end of the connecting plate is fixedly connected to a pressing plate. A sliding groove is provided on the outer wall of the outer shell, and the number of sliding grooves is multiple. Each of the multiple connecting plates is located inside the multiple sliding grooves. A box cover is provided on the front surface of the outer shell. A pressing plate groove is provided on the outer wall of the box cover, and the number of pressing plate grooves is multiple. Each of the multiple pressing plates is located inside the multiple pressing plate grooves. A communication groove is provided on the inner wall of each of the multiple pressing plate grooves, and the communication groove is communicated with the sliding groove. A gasket is provided at the joint between the outer shell and the box cover.

[0006] As a preference, a positioning hole is provided on the outer wall at the front surface of the outer shell, and the number of positioning holes is multiple. A positioning column is fixedly connected to the inner wall of the box cover, and the number of positioning columns is multiple. Each of the multiple positioning columns is located inside the multiple positioning holes.

[0007] As another preference, a positioning frame is fixedly connected to the inside of the box cover, and the outer wall of the positioning frame is in fit with the inner wall of the outer shell.

[0008] Further preferably, heat dissipation grooves are formed on both sides of the inner wall of the housing, and mounting grooves are formed on both outer walls of the housing, and the mounting grooves communicate with the heat dissipation grooves.

[0009] Further preferably, filter frames are fixedly connected to both of the mounting grooves by bolts, a filter screen is fixedly connected to the inner wall of the filter frame, and the position of the filter screen corresponds to the position of the heat dissipation groove.

[0010] Further preferably, a filter screen gasket is provided at the joint between the filter frame and the mounting groove, and the moving plate is cross-shaped.

[0011] Compared with the prior art, the beneficial effects of the present application are as follows:

[0012] (1) In the initial state, multiple pressing plates are all away from the front of the housing. The box cover is installed on the housing. Then, the screw is rotated to drive the moving plate threadedly connected thereto to move away from the housing, so that the moving plate drives multiple connecting plates and the pressing plates respectively connected to the connecting plates to approach the front of the housing until the multiple pressing plates respectively enter multiple pressing plate grooves formed on the outer wall of the box cover. And continue to rotate the screw to press the box cover against the sealing gasket. While the box cover is convenient to install, it can also avoid the uneven force on the box cover caused by using bolts for connection, resulting in a gap between the box cover and the housing and poor sealing performance, thereby causing inverter failure or damage inside the box body. The sealing performance of the entire box body is improved, and the service life of the inverter on the inner wall of the box body is extended. When removing the box cover, rotate the screw in the reverse direction, and for the same principle, the multiple pressing plates are disengaged from the multiple pressing plate grooves in the box cover, facilitating the removal of the box cover.

[0013] (2) Since multiple positioning columns are connected to the inner wall of the box cover and a positioning frame is connected to the inner wall, it is convenient to position the box cover during installation, making the installation of the box cover more convenient. The filter frame and the filter screen are installed on the outer wall of the housing through multiple bolts, which can dissipate heat and prevent dust from entering the inside of the box body. At the same time, the filter screen can be disassembled from the housing by removing the bolts for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

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 steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices

[0027] As shown Figure 1-8 in the easy - forming and highly - sealed inverter box body, it includes a housing 1. A bracket 2 is fixedly connected to the outer wall of the rear end of the housing 1. A moving groove 3 is formed in the outer wall of the bracket 2, and the number of the moving grooves 3 is multiple. A screw rod 4 is movably connected to the outer wall of the rear end of the housing 1. A moving plate 5 is threadedly connected to the outer wall of the screw rod 4. The moving plate 5 includes multiple ends. The multiple ends respectively penetrate through one ends of the multiple moving grooves 3 and are fixedly connected to a connecting plate 6. The other end of the connecting plate 6 is fixedly connected to a pressing plate 7. A sliding groove 8 is formed in the outer wall of the housing 1, and the number of the sliding grooves 8 is multiple. The multiple connecting plates 6 are respectively located inside the multiple sliding grooves 8. A box cover 9 is arranged on the front surface of the housing 1. A pressing plate groove 10 is formed in the outer wall of the box cover 9, and the number of the pressing plate grooves 10 is multiple. The multiple pressing plates 7 are respectively located inside the multiple pressing plate grooves 10. A communication groove 11 is formed in the inner wall of each of the multiple pressing plate grooves 10, and the communication groove 11 is communicated with the sliding groove 8. A sealing gasket 12 is arranged at the joint where the housing 1 and the box cover 9 are attached.

[0028] In the initial state, the multiple pressing plates 7 are all far away from the front surface of the housing 1. The box cover 9 is installed on the housing 1. Subsequently, the screw rod 4 is rotated to drive the moving plate 5 threadedly connected thereto to move away from the housing 1, so that the moving plate 5 drives the multiple connecting plates 6 and the pressing plates 7 respectively connected to the connecting plates 6 to approach the front surface of the housing 1 until the multiple pressing plates 7 respectively enter the multiple pressing plate grooves 10 formed in the outer wall of the box cover 9. And continue to rotate the screw rod 4 to press the box cover 9 against the sealing gasket 12. While the box cover 9 is convenient to install, it can also avoid the uneven force on the box cover 9 caused by using bolts for connection, resulting in a gap between the box cover 9 and the housing 1 and poor sealing performance, thereby causing inverter failures or damages inside the housing 1, improving the sealing performance of the entire housing 1, and extending the service life of the inverter on the inner wall of the housing 1. When removing the box cover 9, rotate the screw rod 4 in the reverse direction. By the same principle, the multiple pressing plates 7 are disengaged from the multiple pressing plate grooves 10 in the box cover 9, facilitating the removal of the box cover 9.

[0029] A positioning hole 13 is formed in the outer wall of the front surface of the housing 1, and the number of the positioning holes 13 is multiple. A positioning column 14 is fixedly connected to the inner wall of the box cover 9, and the number of the positioning columns 14 is multiple. The multiple positioning columns 14 are respectively located inside the multiple positioning holes 13. A positioning frame 15 is fixedly connected to the inside of the box cover 9, and the outer wall of the positioning frame 15 is attached to the inner wall of the housing 1.

[0030] Since the inner wall of the box cover 9 is connected with multiple positioning columns 14 and is also connected with a positioning frame 15, it is convenient to position the box cover 9 during installation, making the installation of the box cover 9 more convenient.

[0031] On both sides of the inner wall of the outer shell 1, heat dissipation grooves 16 are provided. On both outer sides of the outer shell 1, installation grooves 17 are provided. The installation grooves 17 communicate with the heat dissipation grooves 16. Two filter frame 18 are fixedly connected to both installation grooves 17 through bolts. A filter screen 19 is fixedly connected to the inner wall of the filter frame 18. The position of the filter screen 19 corresponds to the position of the heat dissipation groove 16. A filter gasket 20 is provided at the joint between the filter frame 18 and the installation groove 17. The moving plate 5 is cross-shaped.

[0032] The filter frame 18 and the filter screen 19 are installed on the outer wall of the outer shell 1 through multiple bolts, which can dissipate heat while preventing dust from entering the interior of the outer shell 1. At the same time, the filter screen 19 can be removed from the outer shell 1 by removing the bolts for cleaning.

[0033] Working principle: In the initial state, multiple pressing plates 7 are all far away from the front of the outer shell 1. The box cover 9 is installed on the outer shell 1. Then, the screw rod 4 is rotated to drive the moving plate 5 threadedly connected thereto to move away from the outer shell 1, so that the moving plate 5 drives multiple connecting plates 6 and the pressing plates 7 respectively connected to the connecting plates 6 to approach the front of the outer shell 1 until the multiple pressing plates 7 respectively enter multiple pressing plate grooves 10 provided on the outer wall of the box cover 9. And continue to rotate the screw rod 4 to press the box cover 9 against the sealing gasket 12. The box cover 9 is convenient to install and can avoid uneven force on the box cover 9 caused by using bolts for connection, resulting in a gap between the box cover 9 and the outer shell 1 and poor sealing performance, thus causing inverter failure or damage inside the outer shell 1, improving the sealing performance of the entire outer shell 1, and extending the service life of the inverter on the inner wall of the outer shell 1. When removing the box cover 9, rotate the screw rod 4 in the reverse direction. By the same principle, the multiple pressing plates 7 are disengaged from the multiple pressing plate grooves 10 in the box cover 9, which is convenient for removing the box cover 9. Since multiple positioning columns 14 are connected to the inner wall of the box cover 9 and a positioning frame 15 is connected to the inner wall, it is convenient to position the box cover 9 during installation, making the installation of the box cover 9 more convenient. The filter frame 18 and the filter screen 19 are installed on the outer wall of the outer shell 1 through multiple bolts, which can dissipate heat while preventing dust from entering the interior of the outer shell 1. At the same time, the filter screen 19 can be removed from the outer shell 1 by removing the bolts for cleaning.
