Description

Technical Field

[0001] This utility model relates to the technical field of electric loader accessories, specifically to a rear cover for an electric loader. Background Technology

[0002] Electric loaders are construction machines that use electricity to replace traditional fuel. They achieve power output through an electric motor and battery system, featuring zero emissions, low noise, and high energy efficiency. Their core advantages include environmental friendliness, energy saving, and intelligent functions. They are widely used in construction, mining, logistics, and other fields, and are especially suitable for indoor or urban operating environments with strict environmental requirements.

[0003] The rear hood of an electric loader is a protective device that covers the rear of the engine or power system. It is mainly used to protect core components from the influence of the external environment, and also has a heat dissipation function.

[0004] In order to also have a heat dissipation function, the existing rear cover has heat dissipation holes. The size of the heat dissipation holes is relatively large. When used in environments such as material yards, there are many impurities in the air. These impurities can easily enter the interior of the rear cover through the heat dissipation holes, which can easily cause serious damage to the power system and other components protected inside the rear cover.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1-5 As shown, this utility model provides a technical solution: a rear cover for an electric loader, comprising: Rear hood body 1; Side wing sealing mechanism 2 is installed on the side wall of the rear fuselage body 1 and is used to movably seal the side wall of the rear fuselage body 1. Heat dissipation mechanism 3 is located on the top of the rear hood body 1 and is used to supply heat dissipation air into the interior of the rear hood body 1. The side wing sealing mechanism 2 includes a side cover plate 21 and an elastic element 216. The side cover plate 21 is movably inserted into the side of the rear hood body 1. An exhaust groove 211 is provided on the side of the side cover plate 21. A limit rod 212 is fixedly installed on the outer wall of the side cover plate 21. A bar 213 is slidably connected to the outer wall of the limit rod 212. The elastic element 216 moves against the outer wall of the bar 213. When the heat dissipation mechanism 3 is working, the air pressure in the cavity of the rear hood body 1 will increase. The air pressure will push the bar 213 to discharge the air after heat dissipation from the exhaust groove 211. When heat dissipation is stopped, the air pressure will disappear. Through the elastic force of the elastic element 216, the bar 213 can be driven to return to its original position and fit against the outer wall of the side cover plate 21, thus sealing the exhaust groove 211 and preventing impurities in the air from easily entering from there.

[0018] As one implementation method in this embodiment, such as Figure 2 As shown, a mounting block 214 is detachably connected to the outer wall of the side cover plate 21. A support arm 215 is fixedly mounted on the outer wall of the mounting block 214. An elastic element 216 is fixedly mounted on the support arm 215. The mounting block 214 is mounted on the outer wall of the side cover plate 21 by means of screws. Through this connection, the elastic element 216 is modularly designed on the outer wall of the side cover plate 21, and can be replaced after damage.

[0019] As one implementation method in this embodiment, such as Figure 1 As shown, the side wing sealing mechanism 2 also includes a cylindrical member 23, which is fixedly installed on the outer wall of the rear hood body 1. A handle 22 is fixedly installed on the outer wall of the side cover plate 21. The design of the handle 22 makes it easy for the user to hold the side cover plate 21. The side cover plate 21 and the handle 22 are made of engineering plastic. When performing simple maintenance on the components protected by the rear hood body 1, the side cover plate 21 can be disassembled to carry out the work without having to flip the entire rear hood body 1 open, which saves manpower.

[0020] As one implementation method in this embodiment, such as Figure 3 As shown, a limiting plate 24 is rotatably connected to the outer wall of the cylindrical part 23. A positioning bolt 25 is threadedly connected to the outer wall of the limiting plate 24. The threaded end of the positioning bolt 25 is in movable contact with the outer wall of the cylindrical part 23. In the initial state, the limiting plate 24 overlaps with the side of the side cover 21, which is used to limit the side cover 21 to the side of the rear hood body 1. If the side cover 21 needs to be disassembled, the positioning bolt 25 is loosened and then the limiting plate 24 is rotated to make the limiting plate 24 and the side of the side cover 21 no longer overlap. Then the side cover 21 can be pulled out from the rear hood body 1.

[0021] As one implementation method in this embodiment, such as Figure 4 As shown, the heat dissipation mechanism 3 includes a frame 31, which is fixedly connected to the top of the rear hood body 1. A diffuser 32 is fixedly installed on the inner wall of the frame 31, and a connecting cover 33 is fixedly connected to the top of the frame 31. The inner cavity of the rear hood body 1 is connected to the inner cavity of the frame 31. Through the design of the diffuser 32, the heat dissipation air entering the rear hood body 1 can be more uniform, ensuring sufficient heat dissipation.

[0022] As one implementation method in this embodiment, such as Figure 5 As shown, a duct fan 34 is fixedly connected to the top of the connecting cover 33, a hollow chamber 35 is fixedly connected to the top of the duct fan 34, and a protective cover 36 is fixedly installed at the bottom of the hollow chamber 35. The duct fan 34 is controlled to work and deliver air through the connecting cover 33 and the frame 31 into the inner cavity of the rear cover body 1 for heat dissipation. The protective cover 36 is used to protect the air filter 352 from rain.

[0023] As one implementation method in this embodiment, such as Figure 5As shown, a connecting ring 351 is movably inserted into the bottom of the hollow chamber 35, and a connecting block 354 is fixedly installed on the top of the connecting ring 351. A connecting block 355 is fixedly installed on the bottom of the inner wall of the hollow chamber 35, and an air filter 352 is fixedly connected to the bottom of the connecting ring 351. A protrusion 353 is fixedly installed on the bottom of the air filter 352. The hollow chamber 35 is used to connect the inner cavity of the duct fan 34 and the air filter 352. Due to the design of the air filter 352, the heat dissipation air entering the rear cover body 1 can be filtered to ensure the safety of the internal components of the rear cover body 1. When installing the air filter 352, the connecting ring 351 is inserted from the bottom into the hollow chamber 35, and then the connecting ring 351 is rotated to make the connecting block 354 lock into the top of the connecting block 355.

[0024] Working principle: During use, the duct fan 34 is controlled to operate, delivering air through the connecting cover 33 and the square frame 31 into the inner cavity of the rear cover body 1 for heat dissipation. The air filter 352 can filter the heat dissipation air entering the rear cover body 1. When the duct fan 34 is working, the air pressure in the inner cavity of the rear cover body 1 will increase. The air pressure will push the bar 213 to discharge the heat-dissipated air from the exhaust groove 211. When heat dissipation is stopped, the air pressure will disappear. Through the elastic force of the elastic element 216, the bar 213 can be driven to reset and fit against the outer wall of the side cover plate 21, sealing the exhaust groove 211. For simple maintenance, if the side cover plate 21 needs to be disassembled, loosen the positioning bolt 25 and then rotate the limiting plate 24 to prevent the limiting plate 24 from overlapping with the side of the side cover plate 21. Then the side cover plate 21 can be pulled out from the rear cover body 1.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
