It is like the "brain" of the vehicle, mainly responsible for controlling the operation of the motor. It bears the responsibility of battery management. The existing technology protects the electronic control box by setting a dust cover to reduce the impact of the external environment on it.
[0003] During use, the existing insulating dust cover of the electric control box of a tram usually uses a sealing ring to improve the tightness of the connection between the electric control box and the dust cover. A single sealing ring is easily affected by temperature. If it is not replaced in time after a period of use, it will harden and there will be a risk of leakage. The sealing effect is poor, allowing external dust to affect the electric control box.
[0004] Therefore, in response to the above problems, an insulating dust cover for a tram electric control box is proposed. Utility Model Content

[0013] Preferably, a first elastic card block is fixedly connected to the top end of the fixing plate, and a second elastic card block is fitted inside the first elastic card block.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] 1. The present application installs the dust cover body on the electric control box by arranging a dust cover body, a fixed plate, a first spring, a first sealing plate, a second sealing plate, a push rod, a push plate, a rotating shaft and a pressure rod and other structures to cooperate with each other.

[0023] like Figures 1 to 5 As shown, an insulating dust cover for a tram electric control box includes a dust cover body 1. A mounting block is provided on the outside of the dust cover body 1, which can be fixedly connected to the electric control box by internal bolts. A fixing plate 2 is fixedly connected to the bottom surface of the inner wall of the dust cover body 1. A first spring 3 is fitted on one side of the fixing plate 2. A first sealing plate 4 is fitted on one end of the first spring 3. A second sealing plate 5 is fitted on both ends of the first sealing plate 4. A push rod 6 is fixedly connected to one side of the first sealing plate 4. A push plate 7 is fitted on one end of the push rod 6. A rotating shaft 8 is inserted into the middle of the push plate 7. A pressure rod 9 is fixedly connected to one side of the lower part of the push plate 7. The pressure rod 9 is fixedly connected to the first sealing plate 4.
[0024] As a preferred method, the inner side of the first sealing plate 4 is fixedly connected to the first pull plate 10, the interior of the first pull plate 10 is embedded with a connecting plate 11, one end of the connecting plate 11 is fixedly connected to the second pull plate 12, and the top of the second pull plate 12 is fitted with a dustproof net 13. The dustproof net 13 can block and isolate external dust after the outer sealing component ages, thereby improving the performance of use.
[0025] As a preferred method, a sealing gasket 14 is embedded in the upper part of the dust cover body 1, and the sealing gasket 14 is made of rubber. Under the action of the sealing gasket 14, the airtightness between the dust cover body 1 and the electrical control box is improved to prevent dust from entering the interior of the equipment and causing damage to the electrical control box after air leakage.
[0026] As a preferred method, an elastic sleeve 15 is provided on the outer side of the first sealing plate 4, and the elastic sleeve 15 is fitted with the outer side of the second sealing plate 5. The elastic sleeve 15 improves the tightness between the first sealing plate 4 and the second sealing plate 5 and the side wall of the electrical control box, thereby improving the dustproof effect.
[0027] Specifically, a limit block 16 is fitted on one side of the push plate 7, and a second spring 17 is fixedly connected to one side of the limit block 16. During the process of removing the dust cover body 1 and pulling it up, the second spring 17 will apply elastic force to the limit block 16, so that the limit block 16 pushes the push plate 7 to return to its original position, making it easier to use next time.
[0028] Specifically, the two ends of the dustproof net 13 are fixedly connected with a first connecting block 18, the interior of the first connecting block 18 is slidably connected with a slide rod 19, and the outer side of the slide rod 19 is slidably connected with a second connecting block 20. When the device is installed, the first connecting block 18 and the second connecting block 20 are separated, and the slide rod 19 will slide inside it, thereby playing a connecting and supporting role for the dustproof net 13.
[0029] Specifically, a first elastic block 21 is fixedly connected to the top of the fixing plate 2 , and a second elastic block 22 is fitted inside the first elastic block 21 , which facilitates quick installation and removal of the dustproof net 13 , which is convenient and quick.
[0030] Among them, the dustproof net 13 is an existing technology and will not be described in detail; at the same time, this application also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.
[0031] Working principle and process:
[0032] When the staff needs to perform dust-proof treatment on the electric control box, first insert the second elastic block 22 into the inside of the first elastic block 21 to quickly fix the dustproof net 13, then insert the sliding rod 19 into the inside of the first connecting block 18 and the second connecting block 20 in turn, and tighten it with the nut to increase the integrity between the dustproof net 13 and the first pull plate 10, then place the dust cover body 1 on the electric control box, after the position is aligned, press the dust cover body 1 downward so that the inner wall of the electric control box gradually applies pressure to the first sealing plate 4 and the second sealing plate 5, and push the pressure rod 9. The pressure rod 9 pushes the push plate 7 to rotate around the rotating shaft 8. The push plate 7 pushes the push rod 6 to apply thrust to the upper part of the first sealing plate 4 and the second sealing plate 5. The first sealing plate 4 and the second sealing plate 5 push the elastic sleeve 15 so that the elastic sleeve 15 fits tightly with the inner wall of the electric control box, thereby improving the sealing effect and preventing external dust from entering the interior of the electric control box and affecting it. The first sealing plate 4 and the second sealing plate 5 move During this period, the first pull plate 10 and the second pull plate 12 fixedly connected on the inside will be pushed to move, so that the sliding rod 19 slides inside it, so that the dustproof net 13 can maintain the isolation effect. Then, the dust cover body 1 is connected to the electric control box with bolts to complete the installation. Under the action of the sealing gasket 14, the airtightness between the dust cover body 1 and the electric control box is improved to prevent dust from entering the equipment after leakage and causing damage to the electric control box. After a period of use, the sealing gasket 14 and the elastic sleeve 15 are aged. If the sealing effect is reduced without timely replacement, external dust will enter the interior of the dust cover body 1 and will be isolated by the dustproof net 13 to prevent dust from entering the interior of the electric control box, thereby improving the dustproof effect and high safety, avoiding dust from damaging the internal parts of the electric control box and reducing economic losses. When replacing parts, the dust cover body 1 is disassembled. During the pulling-up process, the second spring 17 will apply elastic force to the limit block 16, so that the limit block 16 pushes the push plate 7 to reset, which is convenient for next use.
