Charging piles can be fixed on the ground or on the wall, and are usually installed in parking lots or charging stations in public buildings (such as public buildings, shopping malls, public parking lots, etc.) and residential areas.

[0003] Existing charging piles are generally provided with heat dissipation vents to dissipate heat inside. Since the heat dissipation vents are always connected to the outside world, and the existing charging piles lack an integrated structure that can close the heat dissipation vents when idle, it is easy for external dust to enter the interior of the charging pile, which will cause dust to fall on the surface of electrical components and affect the normal use of the charging pile, thereby shortening the service life of the charging pile.

[0014] As a further improvement of the above solution, the size of the steel ball is matched with the size of the spiral groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is in use, the motor drives the lead screw to rotate, and the sliding cooperation between the guide block and the guide rod can drive the screw tube connected to the lead screw thread to move vertically downward, and the hinged effect between the screw tube and the connecting cross bar and the connecting rod can be used to push the two groups of baffles to move outward at the same time, so as to open the heat dissipation port to dissipate heat inside the charging pile. Conversely, when the present invention is idle, the motor is controlled to reverse, so that the two groups of baffles can be driven to re-close the heat dissipation port, effectively avoiding the problem that it is difficult to close the heat dissipation port when idle, so that external dust can easily enter the interior of the charging pile, thereby causing dust to fall on the surface of the electrical components and affect the normal use of the charging pile.

[0016] 2. In the present invention, when the two groups of baffles move outward to open the heat dissipation port, the movement of the baffles can also drive the connecting plates fixedly connected thereto to move together. When the baffles stop moving, the baffles and the two groups of connecting plates can form a rectangular channel with the charging pile body. When wind blows into the channel, a narrow tube effect will be formed. At this time, the speed of the wind in the channel will be accelerated. Since the pressure is low where the air flow rate is fast, a pressure difference will be formed between the charging pile body and the outside world, thereby accelerating the discharge of heat from the charging pile body, thereby improving the heat dissipation efficiency of the charging pile body, and having strong practicality.

[0017] 3. The dust filter provided in the present invention can isolate dust impurities in the external air to prevent them from entering the interior of the charging pile body and affecting the service life of the device.

[0018] 4. In the process of the baffle moving outward, the present invention utilizes the adsorption effect between the iron block and the magnet block to pull the heat dissipation channel to move together, and utilizes the active cooperation between the sleeve rod and the sleeve tube, so that the spring will be compressed. At the same time, the movement of the heat dissipation channel will also drive the hollow shaft to slide on the outside of the fixed rod, and utilizes the cooperation between the steel ball and the spiral groove, so that the hollow shaft can also rotate during horizontal movement, thereby driving the scraper to rotate to scrape the surface of the dust filter, thereby avoiding clogging caused by dust adhering to the surface of the dust filter. When the heat dissipation channel moves to the outermost part, due to the continued movement of the baffle, the iron block will be separated from the magnet block. At this time, utilizing the rebound effect of the spring, the heat dissipation channel can automatically reset, and the scraper will rotate in the opposite direction to scrape the surface of the dust filter again, thereby ensuring the cleaning effect of the dust filter.

[0019] 5. In the present invention, during the rotation of the scraper, when the end surface of the scraper contacts the knocking ball, as the scraper continues to rotate, the knocking ball can be lifted up by the hinged action between the movable rod and the heat dissipation channel, the sliding cooperation between the slide rod and the slider, and the hinged action between the slider and the movable rod and the connecting rod. At this time, the reset spring will be compressed. When the end surface of the scraper turns away from the knocking ball, the knocking ball will automatically reset to knock on the dust filter by utilizing the rebound effect of the reset spring itself. The vibration generated during the knocking process can shake off the dust, thereby improving the cleaning effect of the dust filter and further improving the practicability of the device.

[0020] 6. The present invention can automatically clean the dust filter during the process of opening the baffle, without the need for extra operating steps, and without the need for operators to dismantle and clean the dust filter. The cleaning method is more convenient and quick, and has a good cleaning effect and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The implementation principle of an electric two-wheeled vehicle fast charging pile with overheat protection in the embodiment of the present application is as follows: by taking the charging gun 2 and connecting it to the vehicle, the vehicle can be quickly charged, and the motor 101 is started at the same time, and the motor 101 drives the screw rod 102 to rotate, and under the sliding cooperation between the guide block 111 and the guide rod 110, the solenoid 103 threadedly connected to the screw rod 102 can be driven to move vertically downward, and the solenoid 103 and the hinged effect between the connecting cross bar 108 and the connecting rod 109 can be used to push the two groups of baffles 106 to move outward at the same time, so as to facilitate the opening of the heat dissipation port to dissipate heat inside the charging pile body 1, and when the two groups of baffles 106 move outward to open the heat dissipation port, the movement of the baffle 106 can also drive the baffles 106 to move with it. The fixedly connected connecting plate 107 moves together, and when the baffle 106 stops moving, the baffle 106 and the two sets of connecting plates 107 can form a rectangular channel with the charging pile body 1. When wind blows into the channel, a narrow tube effect will be formed. At this time, the speed of the wind in the channel will be accelerated. Since the pressure is small where the air flow rate is fast, a pressure difference will be formed between the charging pile body 1 and the outside world, thereby accelerating the discharge of heat inside the charging pile body 1, thereby improving the heat dissipation efficiency of the charging pile body 1. At the same time, in the process of the baffle 106 moving outward, the adsorption effect between the iron block 3 and the magnet block 4 is utilized to pull the heat dissipation channel 104 to move together, and the active cooperation between the sleeve rod 202 and the sleeve 203 is utilized. At this time, the spring 204 will be compressed At the same time, the movement of the heat dissipation channel 104 will also drive the hollow shaft 205 to slide outside the fixed rod 206, and the cooperation between the steel ball 207 and the spiral groove 208 is used to make the hollow shaft 205 rotate while moving horizontally, thereby driving the scraper 209 to rotate to scrape the surface of the dust filter 105, thereby avoiding the dust attached to the surface of the dust filter 105 and causing blockage. When the heat dissipation channel 104 moves to the outermost part, due to the continued movement of the baffle 106, the iron block 3 will be separated from the magnet block 4. At this time, the heat dissipation channel 104 can automatically reset by the rebound effect of the spring 204, and the scraper 209 will rotate in the opposite direction to scrape the surface of the dust filter 105 again, ensuring the cleaning of the dust filter 105. At the same time, during the rotation of the scraper 209, when the end surface of the scraper 209 contacts the knocking ball 2002, as the scraper 209 continues to rotate, and the hinged action between the movable rod 2001 and the heat dissipation channel 104 cooperates, the sliding cooperation between the slide bar 2004 and the slider 2005, and the hinged action between the slider 2005 and the movable rod 2001 and the connecting rod 2006 cooperate, the knocking ball 2002 can be lifted, and the reset spring 2007 will be compressed at this time. When the end surface of the scraper 209 turns away from the knocking ball 2002, the knocking ball 2002 will automatically reset to knock on the dust filter 105 by utilizing the rebound effect of the reset spring 2007 itself. The vibration generated during the knocking process can shake off the dust.Thereby, the cleaning effect of the dust filter 105 is improved. After charging is completed, the charging gun 2 is separated from the vehicle and put back to its original position. At this time, the motor 101 is started to reverse, so that the two sets of baffles 106 re-close the heat dissipation port, effectively avoiding the problem that it is difficult to close the heat dissipation port when idle, so that external dust can easily enter the interior of the charging pile, thereby causing dust to fall on the surface of electrical components and affect the normal use of the charging pile. Example

[0029] The present embodiment is further improved on the basis of the embodiment 1 in that the knocking ball 2002 is made of rubber material and is fixedly connected to the movable rod 2001 by fixing bolts, so that the knocking ball 2002 can be replaced when it is damaged after long-term use.

[0030] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
