Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to an adjustable-speed active cooling DC charging pile with a dustproof filter. Background Technology

[0002] Charging piles are charging devices that provide energy replenishment for electric vehicles. Their function is similar to a gas pump at a gas station. They can be fixed to the ground or walls and installed in public areas (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels. DC charging piles are public charging devices that directly output adjustable DC power from a three-phase four-wire 380V AC power grid, with charging power ranging from 30kW to 300kW. As of August 2024, China had 1.461 million DC charging piles, accounting for 44.8% of the total number of public charging piles. They adopt a nine-hole gun design and an integrated DC power meter, achieving fast charging in 0.5-2 hours without an on-board charger. They are mainly deployed in highway service areas and urban public charging stations. The market share of DC charging piles in Europe is expected to increase to 26% by 2025, with the global market size growing at a compound annual growth rate of over 56%.

[0003] Some existing adjustable-speed active cooling DC charging piles typically do not have dust filters on their heat dissipation vents. This makes it easy for dust and other impurities to enter the charging pile through the vents, affecting the operation of the electronic components inside the charging pile. Moreover, some adjustable-speed active cooling DC charging piles with dust filters have dust filters that are difficult to remove, making it inconvenient to remove them for cleaning or replacement.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-6As shown, this utility model provides an adjustable-speed active cooling DC charging pile with a dust filter, including a housing 1. Both sides of the housing 1 have heat dissipation vents 101. A dust filter 3 can be detachably installed inside each of the two heat dissipation vents 101. Limiting components 4 are installed inside each of the two heat dissipation vents 101. Each limiting component 4 includes two mirror-distributed limiting plates 403, which are hinged to the inner sides of the corresponding heat dissipation vent 101. Worm gears 404 are fixedly installed at the top of each of the four limiting plates 403. Drive shafts 401 are rotatably installed inside the top of each of the two heat dissipation vents 101. Worms 405 are fixedly installed at both ends of each of the two drive shafts 401, and the worms 405 mesh with the corresponding worm gears 404. Adjacent worms 405 rotate in opposite directions. A knob 402 is fixedly installed at one end of the shaft 401. Baffles 102 are fixedly installed at the upper and lower ends of the two heat dissipation vents 101. The outer shell 1 is the shell of an existing adjustable speed active cooling DC charging pile. The dust filter 3 can be installed inside the heat dissipation vent 101 so that the upper and lower ends of the inner side of the dust filter 3 are in contact with the corresponding baffles 102. Then, the knob 402 drives the drive shaft 401 to rotate. The drive shaft 401 drives the two worm gears 405 to rotate synchronously in opposite directions. The worm gears 405 drive the worm wheel 404 to rotate. The worm wheel 404 drives the limit plate 403 to rotate, so that the inner side of the limit plate 403 is in contact with the outer edge of the dust filter 3 to limit the dust filter 3. The above steps can be reversed to release the limit of the dust filter 3, so that the dust filter 3 can be removed for cleaning or replacement.

[0020] Louvers 2 are hinged to the heat dissipation vents 101 on both sides of the outer casing 1. Locking assemblies 5 are installed at the heat dissipation vents 101 on both sides of the outer casing 1. Each locking assembly 5 includes a sliding groove 501, which is fixedly installed on both sides of the outer casing 1. Limiting rods 502 are slidably installed within each of the two sliding grooves 501. A lever 503 is fixedly installed at one end of each of the two limiting rods 502. A spring 504 is fixedly installed within each of the two sliding grooves 501, with one end of the spring 504 engaging with the corresponding limiting rod 502. One end of 02 is fixedly connected, and each of the two louvers 2 has a limiting groove 505 on one side. One end of the limiting rod 502 can be inserted into the corresponding limiting groove 505. The louvers 2 can protect the dustproof net 3 in the heat dissipation vent 101. When it is necessary to remove the dustproof net 3, the lever 503 can be used to drive the limiting rod 502 out of the limiting groove 505 on the louvers 2, so that the limiting rod 502 retracts into the slide groove 501 and compresses the spring 504. The rebound force of the spring 504 can be used to reset the limiting rod 502.

[0021] Working principle: When in use, the dustproof net 3 can be installed inside the heat dissipation vent 101 to prevent dust and other impurities from entering the charging pile through the heat dissipation vent 101. The louver 2 can protect the dustproof net 3 inside the heat dissipation vent 101. When it is necessary to remove the dustproof net 3, the lever 503 can be used to drive the limiting rod 502 to be pulled out from the limiting groove 505 on the louver 2, so that the limiting rod 502 retracts into the sliding groove 501 and compresses the spring 504, thereby releasing the limitation on the louver 2 and opening the louver 2. By setting the locking component 5, the louver 2 can be limited and released by the locking component 5, thereby facilitating the installation and removal of the dustproof net 3.

[0022] Next, the knob 402 drives the drive shaft 401 to rotate, and the drive shaft 401 drives the two worm gears 405 to rotate synchronously in opposite directions. The worm gears 405 drive the worm wheel 404 to rotate, and the worm wheel 404 drives the limiting plate 403 to rotate, so that the outer side of the limiting plate 403 fits against the inner sides of the heat dissipation vent 101, thereby releasing the limit on the dustproof mesh 3. Thus, the dustproof mesh 3 can be removed for cleaning or replacement. By setting the limiting component 4, the dustproof mesh 3 can be limited and released, thereby achieving the purpose of easy disassembly and assembly of the dustproof mesh 3.

[0023] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
