[0002] A charging pile is a device that provides electrical energy replenishment for electric vehicles, electric motorcycles, electric bicycles, etc. Its appearance is usually similar to a fuel dispenser. It efficiently transmits the electrical energy in the power grid to the vehicle's battery pack by connecting to the charging interface of the electric vehicle, enabling the vehicle to regain the energy required for driving. However, the charging pile is prone to overheating during use. Once the charging pile overheats, it may trigger a fire. The spread speed of the fire is extremely fast, and it is easy to lead the fire to the electric vehicle connected to it through the charging cable. Due to the fact that the battery of the electric vehicle may undergo thermal runaway under the action of high temperature and fire, further intensifying the fire, thus posing a serious threat to the surrounding vehicles, facilities, and personnel safety.

[0016] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0017] Please refer to Figures 1-7 , as shown in the figure, a flame - retardant charging pile provided in this embodiment, such as Figures 1-3As shown, it includes a charging pile body 1, the charging pile body 1 includes an outer protective cover body 101, an inner protective cover body 102 is installed inside the outer protective cover body 101, and a flow guide air intake mechanism 2 is installed at the bottom of the charging pile body 1, and the flow guide air intake mechanism 2 includes an airflow guide pipe 21 fixedly connected to the outer protective cover body 101 and the bottom of the inner protective cover body 102, and one end of the airflow guide pipe 21 extending out of the bottom of the outer protective cover body 101 is connected to a cylindrical air intake sleeve 22, specifically, a plurality of air intake filter holes are provided on the side wall of the cylindrical air intake sleeve 22, which are used to inhale external air and block and filter impurities. An electric fan 23 is rotatably installed at one end of the airflow guide pipe 21 extending into the inner protective cover body 102.

[0018] Combination Figures 4-5 As shown, the bottom of the electric fan 23 is fixedly connected with a transmission rotating rod 24 that passes through the cylindrical air intake sleeve 22, and an anti-dust accumulation plate 28 is fitted on the side wall of the cylindrical air intake sleeve 22. The anti-dust accumulation plate 28 is transmission-connected to the transmission rotating rod 24. When the electric fan 23 is started, the transmission rotating rod 24 can drive the anti-dust accumulation plate 28 to slide on the side wall of the cylindrical air intake sleeve 22.

[0019] Furthermore, one end of the transmission rotating rod 24 extending out of the bottom of the cylindrical air intake sleeve 22 is fixedly connected to a first connecting limit rod 25, the other end of the first connecting limit rod 25 is fixedly connected to a second connecting limit rod 26, the other end of the second connecting limit rod 26 is fixedly connected to a third connecting limit rod 27, the other end of the third connecting limit rod 27 is fixedly connected to the anti-dust accumulation plate 28, and the third connecting limit rod 27 presses the anti-dust accumulation plate 28 against the side wall of the cylindrical air intake sleeve 22.

[0020] Specifically, the first connecting limit rod 25 is entirely horizontally arranged below the cylindrical air intake sleeve 22, the second connecting limit rod 26 is vertically arranged above the first connecting limit rod 25, and the third connecting limit rod 27 is horizontally arranged on the top of the second connecting limit rod 26 close to the side of the cylindrical air intake sleeve 22.

[0021] It can be understood that during actual use, when the electric fan 23 is started to rotate, external gas enters the interior of the cylindrical intake sleeve 22 through the intake filter holes on the side wall of the cylindrical intake sleeve 22, and then enters the interior of the inner protective cover body 102 after passing through the air flow guiding pipe 21 to dissipate heat and cool down the charging pile main body 1. At the same time, the rotating electric fan 23 synchronously drives the transmission rotating rod 24 to start rotating, and then the first connection limiting rod 25 drives the second connection limiting rod 26 and the third connection limiting rod 27 to rotate around the outer wall of the cylindrical intake sleeve 22, so that the dust-proof plate 28 slides along the outer wall of the cylindrical intake sleeve 22, thereby achieving the purpose of scraping the dust adsorbed at the intake filter holes. During the above process, when the electric fan 23 is started, it can circulate the hot air inside the inner protective cover body 102 and the outer protective cover body 101, and at the same time, scrape off the dust and impurities adhering to the outer wall of the cylindrical intake sleeve 22, avoiding the accumulation of dust at the intake to form a heat resistance, and further avoiding overheating of the internal electronic components of the charging pile caused thereby, reducing the self-ignition risk of the charging pile main body 1, and reducing the later maintenance cost.

[0022] It should be noted that during actual use, although the dust-proof plate 28 can scrape off the dust on the surface of the cylindrical intake sleeve 22, it often cannot effectively clean the dust accumulated in the intake filter holes. Therefore, the diversion intake mechanism 2 can be further specifically designed as follows:

[0023] Refer to Figure 5 As shown, the diversion intake mechanism 2 further includes a positioning tube sleeve 210 installed above the first connection limiting rod 25. Specifically, a horizontally arranged positioning tube sleeve 210 is fixedly installed above the first connection limiting rod 25 and at a position below the cylindrical intake sleeve 22.

[0024] A dynamic sliding insertion rod 211 is slidably installed inside the positioning tube sleeve 210 through a telescopic spring 217. A hexagonal sliding frame 29 is fixedly arranged on the bottom surface of the cylindrical intake sleeve 22. A vibration trigger slide plate 216 fixedly connected to the dynamic sliding insertion rod 211 is slidably connected inside the hexagonal sliding frame 29. Specifically, an arc-shaped transition structure can be provided at the inner corner of the hexagonal sliding frame 29 to facilitate the sliding of the vibration trigger slide plate 216 inside the hexagonal sliding frame 29.

[0025] The transmission rotating rod 24 can drive the vibration trigger slide plate 216 to slide inside the hexagonal sliding frame 29, and then drive the dynamic sliding insertion rod 211 to perform reciprocating telescopic motion inside the positioning sleeve.

[0026] One end of the dynamic sliding rod 211 is fixedly connected to a translation rocker arm 212. Specifically, one end extending out of the inner cavity of the positioning sleeve 210 is fixedly connected to a translation rocker arm 212 that is vertically arranged therewith. One side of the translation rocker arm 212 is fixedly provided with a vibration ball 214 that is fixedly connected thereto via a knocking rod 213.

[0027] Specifically, by making the dynamic sliding rod 211 reciprocate and horizontally displace in the inner cavity of the positioning sleeve 210, the translation rocker arm 212 can be synchronously driven and the knocking rod 213 and the vibration ball 214 can be reciprocated and horizontally displaced, and then the vibration ball 214 can reciprocate and knock on the side wall of the cylindrical air intake sleeve 22, so as to knock and vibrate the dust accumulated in the air intake filter hole to avoid the problem of clogging of the air intake filter hole affecting gas circulation.

[0028] In the initial state, the vibration ball 214 is fitted to the side wall of the cylindrical air intake sleeve 22 . When the vibration triggering slide plate 216 slides to the inner angle of the hexagonal slide frame 29 , the vibration ball 214 is separated from the side wall of the cylindrical air intake sleeve 22 .

[0029] More specifically, the telescopic spring 217 is always in a compressed state and generates a rebound force to lift the dynamic sliding rod 211 to move outward from the positioning sleeve 210. When the vibration trigger slide 216 moves to the inner angle position of the hexagonal slide frame 29, the knocking rod 213 and the vibration ball 214 as a whole also move away from the outer wall of the cylindrical air intake sleeve 22 synchronously. When the vibration trigger slide 216 moves to the position between the inner angles of the hexagonal slide frame 29, the distance between this position and the center point of the transmission rotating rod 24 is shortened, thereby pressing the vibration trigger slide 216 to make the dynamic sliding rod 211 as a whole shrink toward the position of the telescopic spring 217, thereby driving the translation rocker arm 212 to translate toward the direction of the cylindrical air intake sleeve 22. This translation process will cause the vibration ball 214 on the knocking rod 213 to hit the outer wall of the cylindrical air intake sleeve 22.

[0030] It can be understood that during actual use, when the electric fan 23 is started to drive the transmission rotating rod 24 to rotate, the first connection limiting rod 25 synchronously drives the positioning sleeve 210, the dynamic sliding insert rod 211 and the translation swing rod 212 to rotate synchronously as a whole. By combining the contact between the vibration trigger slide plate 216 and the inner wall of the hexagonal sliding frame 29, as the distance between the inner wall of the hexagonal sliding frame 29 and the center point of the transmission rotating rod 24 is in a reciprocating change state, the whole dynamic sliding insert rod 211 can reciprocate and translate in the inner cavity of the positioning sleeve 210, and then the knocking rod 213 and the vibration ball 214 synchronously reciprocate and translate to intermittently knock the outer wall of the cylindrical air intake sleeve 22. During the above process, when the outer protective cover 101 and the inner protective cover 102 are circulated with external air by starting the electric fan 23, the heat generated by the components inside the outer protective cover 101 and the inner protective cover 102 during operation is carried out. At the same time, combined with the rotation of the transmission rotating rod 24, the first connection limiting rod 25 synchronously drives the second connection limiting rod 26 and the whole dynamic sliding insert rod 211 to rotate and displace on the outer wall of the cylindrical air intake sleeve 22. That is, when the dust-proof plate 28 scrapes impurities on the outer wall of the cylindrical air intake sleeve 22, the dynamic sliding insert rod 211 drives the knocking rod 213 and the vibration ball 214 to reciprocate and translate on the outer wall of the cylindrical air intake sleeve 22, and then the outer wall of the cylindrical air intake sleeve 22 can be synchronously knocked and vibrated reciprocally and intermittently to shake off the impurities in the air intake filter holes, further improving the anti-blocking and anti-dust accumulation ability of the air guiding and intake mechanism 2 and reducing the maintenance cost.

[0031] Furthermore, a through-shaped limiting groove 215 is formed inside the translation swing rod 212. The third connection limiting rod 27 is installed in the inner cavity of the limiting groove 215 in a horizontal sliding state, and the third connection limiting rod 27 is arranged at the horizontal center line position of the limiting groove 215. Specifically, the purpose of such a setting is that when the transmission rotating rod 24 is rotated to drive the third connection limiting rod 27 and the dust-proof plate 28 rotates and scrapes the outer wall of the cylindrical air intake sleeve 22 synchronously, when the whole translation swing rod 212 reciprocates and translates synchronously and the vibration ball 214 knocks the outer wall of the cylindrical air intake sleeve 22, due to the setting of the limiting groove 215, the moving range of the whole translation swing rod 212 is limited, but it will not affect the displacement work of the whole third connection limiting rod 27 and the dust-proof plate 28.

[0032] Further, the tapping rods 213 and the vibrating balls 214 are arranged in a one-to-one correspondence. The number of the tapping rods 213 and the vibrating balls 214 is set to two, and both of the two tapping rods 213 and the vibrating balls 214 are symmetrically arranged with respect to the horizontal center line of the cylindrical air inlet sleeve 22. Specifically, the purpose of such a setting is to make the tapping force received by the outer wall of the cylindrical air inlet sleeve 22 more uniform and symmetric, thereby increasing the stability of the cylindrical air inlet sleeve 22, making the stress state of the cylindrical air inlet sleeve 22 more balanced, reducing the risk of possible distortion or deformation, and helping to extend the service life of the cylindrical air inlet sleeve 22.

[0033] Further, referring to Figure 3 As shown, first air outlet grooves 103 are formed on both sides of the outer protection cover body 101, and second air outlet grooves 104 are formed on both sides of the inner protection cover body 102. Both of the two second air outlet grooves 104 are arranged above the first air outlet grooves 103. Specifically, the purpose of such a setting is that when the electric fan 23 is started to rotate to conduct heat exchange and circulation of the hot air inside the outer protection cover body 101 and the inner protection cover body 102, by making the gas flow through the first air outlet grooves 103 and the second air outlet grooves 104 with high and low staggering in the inner cavities of the outer protection cover body 101 and the inner protection cover body 102, the flow path of the air flow can be increased, and the air can flow more easily between the outer protection cover body 101 and the inner protection cover body 102, so that the temperature inside the charging pile main body 1 is more evenly distributed to prevent problems generated in the hot spot area inside the inner protection cover body 102.

[0034] It should be noted that the charging pile main body 1 may still catch fire during charging. In order to prevent the fire of the charging pile main body 1 from spreading to the charging vehicle body, a combustion blocking mechanism 3 can be designed as follows:

[0035] Further preferably, in combination with Figures 6-7 As shown, a combustion blocking mechanism 3 is further included. The combustion blocking mechanism 3 includes a charging base 31 fixedly installed on one side of the outer protection cover body 101. A protective cover 32 is fixedly installed on one side of the outer protection cover body 101. A directional cylinder 33 fixedly connected to the outer protection cover body 101 is arranged on the outer wall of the charging base 31. A plurality of flame retardant sliding frames 34 are fixedly installed at one end of the directional cylinder 33, and a first flame retardant plate 35 is slidably installed in the inner cavities of the plurality of flame retardant sliding frames 34. A second flame retardant plate 36 is fixedly connected to one side of each of the plurality of first flame retardant plates 35 extending out of the inner cavity of the flame retardant sliding frame 34.

[0036] Specifically, the directional cylinder 33, the flame retardant sliding frames 34, the first flame retardant plates 35 and the second flame retardant plates 36 can be made of rock wool or glass fiber.

[0037] Specifically, the purpose of such a setting is to enable the fiber structures inside the orientation cylinder 33, the flame-retardant carriage 34, the first flame-retardant plate 35, and the second flame-retardant plate 36 to effectively block the conduction of air and heat, thus playing a fire-prevention role. The purpose of such a setting is that after connecting the charging cable to the charging base 31 and the vehicle to be charged, multiple first flame-retardant plates 35 synchronously move towards the center of the charging base 31 until multiple second flame-retardant plates 36 enclose and clamp the outer wall of the charging cable. While assisting in clamping and limiting the charging cable, when there is an open fire inside the charging pile main body 1 or at the charging port of the vehicle to be charged and the fire spreads along the charging cable, the open fire preferentially contacts the second flame-retardant plate 36 to play a role in isolating the fire source, so as to reduce fire losses.

[0038] Meanwhile, in combination with Figures 6-7 As shown, a steering plate 37 is rotatably installed on one side of each of the multiple flame-retardant carriages 34. A plurality of through-shaped guide grooves 38 are formed inside the steering plate 37. The plurality of guide grooves 38 are all arc-shaped, and a guide rod 39 fixedly connected to the first flame-retardant plate 35 is slidably installed in the inner cavity of each of the plurality of guide grooves 38. A rack 310 is fixedly installed on the outer wall of the steering plate 37, and an electric gear disk 311 rotatably connected to the outer protective cover body 101 meshes with the outer wall of the rack 310.

[0039] In the normal state, the plurality of guide rods 39 move on the side of the guide groove 38 close to the outer wall of the steering plate 37. At this time, the plurality of first flame-retardant plates 35 synchronously move and retract into the inner cavity of the flame-retardant carriage 34, and the distance between the plurality of second flame-retardant plates 36 is relatively large. After the charging cable is fixedly connected to the charging base 31, by driving the electric gear disk 311 to rotate, the steering plate 37 can be deflected as a whole, and then the guide rod 39 gradually moves towards the inner wall of the steering plate 37 in the inner cavity of the guide groove 38 until the plurality of second flame-retardant plates 36 are synchronously clamped and limited on the outer wall of the charging cable, so as to adapt to charging cables of different thickness specifications for limiting and protecting, making it more convenient and safe to use and more convenient for actual use.

[0040] In specific implementation, after connecting the charging cable to the charging base 31 and connecting the charging cable to the vehicle to be charged, by starting the electric gear disk 311 to drive the rack 310 to rotate the steering plate 37 as a whole, the plurality of guide rods 39 slide in the inner cavity of the guide groove 38, and the plurality of first flame-retardant plates 35 synchronously slide inside the flame-retardant carriage 34, so that the plurality of second flame-retardant plates 36 gradually approach the outer wall of the charging cable and clamp and limit it, so that the outer wall of the charging cable can be separated, limited and protected. When there is an open fire and it burns along the charging cable, the open fire can be flame-retarded when it contacts the first flame-retardant plate 35 and the second flame-retardant plate 36, so as to prevent the continuous spread of the open fire.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
