Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of charging piles, in particular to a mute charging pile. BACKGROUND

[0002] During use of an electric vehicle charging pile, the operating noise of internal components and the heat dissipation system has become a significant problem affecting the comfort of the surrounding environment. The noise is mainly caused by the operation sound of components, airflow howling when the fan is running, blade rotation sound, and the sound of high-speed airflow impacting the heat dissipation grille.

[0003] The existing patent application with patent publication number CN117067966B, published on December 26, 2023, is entitled "Charging pile" and includes a box body, a cabinet door, a cable, and a winding mechanism. The upper inside of the box body is provided with a storage cabinet. The winding mechanism includes a first limiting box, a first sliding block, a first connecting rod, a sliding winch, a second connecting rod, two second sliding blocks, and two second limiting boxes. The right side of the first limiting box is provided with a first limiting groove extending along its length. One end of the first connecting rod is fixedly arranged on the first sliding block. The left or right side of the second limiting box is provided with a second limiting groove extending along its length. The sliding winch is fixedly arranged on the second connecting rod. One end of the cable is wound around the sliding winch, and the other end of the cable is fixedly provided with a charging gun. The charging gun is arranged on the first connecting rod. The present application provides a charging pile to solve the problem of easy damage to the cable of the existing charging pile.

[0004] The above-mentioned application has the following deficiencies: To solve the problem of heat dissipation of the charging pile, a horizontal louvered air inlet and air outlet design is usually used, and the air inlet and air outlet are flat, which allows the airflow noise generated by the heat dissipation fan to spread and propagate in all directions without obstruction, resulting in a large noise pollution range. The open structure cannot effectively shield or guide the noise. When the charging pile does not need to be charged or has low heat dissipation demand, the fan can stop or run at low speed. If noise reduction is achieved by blocking the air inlet and air outlet, the heat dissipation and moisture-proof performance of the charging pile during low-power operation cannot be guaranteed. SUMMARY

[0005] The present application aims to provide a mute charging pile to solve the above-mentioned deficiencies in the prior art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0007] The utility model provides a mute charging pile, including the pile body, still including a pair of cable frame, which installs respectively in the both sides of pile body, the both sides of the both sides of pile body are opened with the air inlet and the air outlet respectively, air inlet and air outlet are located below cable frame respectively, the elastic support mechanism is inserted in cable frame, mute adjusting cover, each mute adjusting cover is slidably installed outside air inlet and air outlet, the bottom of mute adjusting cover is equipped with the opening, transmission adjusting mechanism, which is installed in the inside of pile body, is connected with elastic support mechanism and mute adjusting cover respectively, when the cable is overlapped on the cable frame, the elastic support mechanism is pressed down to control the mute adjusting cover to move up and radiate heat through transmission adjusting mechanism.

[0008] Preferably, the pile body is provided with an air inlet channel communicated with the air inlet and an air outlet channel communicated with the air outlet, and soundproof cotton is installed in the air inlet channel and the air outlet channel.

[0009] Preferably, the elastic support mechanism comprises an insertion rod inserted through the top of the cable frame, a supporting plate fixedly connected to the top end of the insertion rod, and a top spring sleeved on the insertion rod, with the two ends of the top spring abutting against the supporting plate and the cable frame respectively.

[0010] Preferably, the transmission adjusting mechanism comprises a connecting frame slidably installed on the inner side wall of the pile body, one side of the connecting frame connected to the insertion rod, and the other side of the connecting frame in transmission connection with the mute adjusting cover.

[0011] Preferably, transmission gears are rotatably connected to the inner walls of the air inlet and the air outlet, a driving rack vertically arranged on the connecting frame in meshing engagement with the transmission gears, and driven racks fixedly connected to the inner walls of the mute adjusting cover in meshing engagement with the transmission gears.

[0012] Preferably, an impeller is rotatably connected to the position of the air outlet channel close to the air outlet, sound-absorbing layers arranged on both sides of the blades of the impeller, and an arc-shaped sound-absorbing pad fixedly connected to the air outlet channel below the impeller.

[0013] Preferably, a baffle is hingedly connected to the inner side wall of the air outlet channel above the impeller, a pair of wedge-shaped top blocks fixedly connected to the inner side of the connecting frame in abutting engagement with the baffle, the baffle abutting against the inner wall of the air outlet channel when the cable is overlapped on the elastic support mechanism, and the connecting frame pushing the baffle upward to make it tilt when the cable is away from the elastic support mechanism.

[0014] Preferably, noise reduction sealing cover plates are hingedly connected to the both sides of the pile body, and a plurality of sound-absorbing strips are installed in the inner side of the noise reduction sealing cover plates along the direction of air flow.

[0015] Preferably, a sound-absorbing partition is installed in the pile body, the air outlet channel is between the sound-absorbing partition and the noise reduction sealing cover plate, and a plurality of sound-absorbing cottons are embedded in the sound-absorbing partition.

[0016] Preferably, the pile body is provided with a sound-absorbing box on both sides, and the top surface of the sound-absorbing box corresponds to the opening of the sound adjustment cover, and the bottom surface of the sound-absorbing box is in contact with the ground.

[0017] In the above technical solution, by changing the traditional horizontal louver form of the air inlet and air outlet from the side to the downward position on the side of the pile body and adding the downward extension of the sound adjustment cover, the design guides the air inlet and air outlet to the area below the charging pile, effectively absorbs and blocks sound waves, changes the direction of noise at the initial stage of propagation, and realizes physical layer sound energy attenuation by limiting the propagation space and the sound absorption effect of the ground. When the cable is completely placed on the elastic supporting mechanism of the cable holder, the charging pile is in an uncharged state, the cable gravity presses the elastic supporting mechanism, triggering the transmission adjustment mechanism to drive the sound adjustment cover to move up, which exposes the air inlet / outlet and forms a low-resistance preliminary heat dissipation channel under the condition of reducing the shielding, which can meet the low-power heat dissipation requirement of the fan in the standby state of the charging pile. At this time, the exposed air inlet / outlet does not cause significant noise diffusion problem. When the user pulls out the cable for charging, the elastic supporting mechanism automatically rebounds to the original position under the action of its own reset force, which reversely drives the transmission adjustment mechanism, so that the sound adjustment cover completely moves down. At this time, the sound adjustment cover completely covers the air inlet / outlet. When the fan starts to run at high speed for forced heat dissipation, the high-pressure hot air flow is forced to pass through the opening at the bottom of the sound adjustment cover and is discharged downward. The high-speed air flow sprayed downward mainly impacts the ground or the pile base area, and the sound wave energy is quickly absorbed and scattered by the hard ground and surrounding structures, effectively preventing the horizontal diffusion of noise to the height of human ears. The closed cover also has a significant physical blocking effect on high-frequency air flow noise, and the noise reduction mode is accurately switched as needed.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the present disclosure.

[0032] Please refer to Figures 1-8 ​The embodiment of the present application provides a kind of mute charging pile, including pile body 1, still including a pair of cable rack 2, it is respectively installed in the both sides of pile body 1, and the air inlet 3 and the air outlet 4 are respectively set up in the both sides of pile body 1, air inlet 3 and air outlet 4 are respectively located below cable rack 2, and elastic support mechanism 5 is inserted in cable rack 2, mute adjustment cover 6, each mute adjustment cover 6 is respectively slidably installed in the outside of air inlet 3 and air outlet 4, and opening 601 is equipped in the bottom of mute adjustment cover 6, transmission adjustment mechanism 7, it is installed in the inside of pile body 1, respectively with elastic support mechanism 5 and mute adjustment cover 6 is connected, when cable is overlapped on cable rack 2, press down elastic support mechanism 5 to control mute adjustment cover 6 to move up and radiate heat by transmission adjustment mechanism 7.

[0033] Specifically, the pile body 1 is the main structure of the charging pile, and a plurality of heat dissipation fans, electrical modules and transmission members for accelerating airflow circulation are installed inside. The cable rack 2 is used to facilitate the owner to place the charging cable after completing the charging. The charging cable placed on the cable rack 2 is placed on the elastic supporting mechanism 5. The operation mode of the charging pile automatically switches the noise reduction and heat dissipation strategy according to the cable placement state. The air inlet 3 and the air outlet 4 are changed from the traditional horizontal louver form on the side to the position downwardly arranged on the side of the pile body 1 and the silent adjusting cover 6 is added to extend downward. This design guides the direction of air inlet and air outlet to the area below the charging pile, which can effectively absorb and block sound waves, so that the noise changes direction at the initial stage of propagation, and the sound energy is attenuated at the physical level by limiting the propagation space and the sound absorption of the ground. When the cable is completely placed on the elastic supporting mechanism 5 of the cable rack 2, the charging pile is in the uncharged state. The cable gravity presses the elastic supporting mechanism 5, triggering the transmission adjusting mechanism 7 to drive the silent adjusting cover 6 to move upward. This makes the opening area of the air inlet 3 and the air outlet 4 exposed, forming a low-resistance preliminary heat dissipation channel, which can meet the low-power heat dissipation demand of the fan in standby state. At the same time, due to the exposure of the air outlet, it is beneficial to the rapid flow and start-up acceleration response of air at the initial stage of fan start-up. Although the air outlet is open, the fan runs at low speed, stops or runs for a short time due to the standby or low-power state of the equipment, which meets the basic heat dissipation demand in standby state, such as transformer temperature control, display system heat dissipation, etc. The overall noise level is low itself. At this time, the exposed air outlet does not cause significant noise diffusion problem. When the user pulls out the cable wound on the cable rack 2 for charging, the elastic supporting mechanism 5 loses the cable gravity and is pressed to disappear. Under the action of its own restoring force, it automatically rebounds to the original position. This action reversely drives the transmission adjusting mechanism 7, so that the silent adjusting cover 6 moves downward completely. At this time, the silent adjusting cover 6 completely covers the air outlet, and only the bottom opening 601 is left as the only air outlet or inlet channel. When the fan starts to run at high speed for forced heat dissipation, the high-pressure hot air flow is forced to pass through the opening 601 at the bottom of the silent adjusting cover 6 and is discharged downward. The high-speed airflow sprayed downward mainly impacts the ground or the base area of the pile body 1, and the sound wave energy is quickly absorbed and scattered by the hard ground and surrounding structures, effectively preventing the horizontal diffusion of noise to the height of human ear. At the same time, the closed cover body has a significant physical blocking effect on the high-frequency airflow noise, accurately switches the noise reduction mode as needed, ensures the rapid heat dissipation of the charging pile when the fan is in standby state, and significantly attenuates the propagation energy and distance of the fan high-frequency operation noise.

[0034] Compared with the prior art, the embodiment of the present application changes the traditional lateral louver form of the air inlet 3 and the air outlet 4 from the side to a downward position on the side of the pile body 1 and adds a noise adjustment cover 6 extending downward. This design guides the air inlet and outlet to the area below the charging pile, effectively absorbs and blocks sound waves, changes the direction of noise at the initial stage of propagation, and realizes physical layer sound energy attenuation by limiting the propagation space and the sound absorption effect of the ground. When the cable is completely placed on the elastic supporting mechanism 5 of the cable rack 2, the charging pile is in an uncharged state, the cable gravity presses the elastic supporting mechanism 5, triggers the transmission adjustment mechanism 7 to drive the noise adjustment cover 6 to move upwards, which exposes the air inlet and forms a low-resistance preliminary heat dissipation channel under the condition of reducing shielding, which can meet the low-power heat dissipation requirement of the charging pile in the standby state of the fan. At this time, the exposed air inlet does not cause significant noise diffusion problem. When the user pulls out the cable for charging, the elastic supporting mechanism 5 automatically rebounds to the original position under the action of its own reset force, which reversely drives the transmission adjustment mechanism 7, so that the noise adjustment cover 6 completely moves downwards. At this time, the noise adjustment cover 6 completely covers the air inlet. When the fan starts to run at high speed for forced heat dissipation, the high-pressure hot air flow is forced to pass through the opening 601 at the bottom of the noise adjustment cover 6 and is discharged downward. The high-speed airflow sprayed downward mainly impacts the ground or the base area of the pile body 1, and the sound wave energy is quickly absorbed and scattered by the hard ground and the surrounding structures, effectively preventing the horizontal diffusion of noise to the height of the human ear. The closed cover also has a significant physical blocking effect on high-frequency airflow noise, and the noise reduction mode is accurately switched as needed.

[0035] In a further practical example of the present application, the pile body 1 is provided with an air inlet channel 301 communicating with the air inlet 3 and an air outlet channel 401 communicating with the air outlet 4. Soundproof cotton 8 is installed in the air inlet channel 301 and the air outlet channel 401. Specifically, in the standby mode of the charging pile, the soundproof cotton 8 absorbs low-speed airflow noise, and in the charging mode, the soundproof cotton 8 further suppresses the noise of high-speed airflow in the air duct. When the charging fan runs at full speed, the hot airflow enters the air outlet channel 401. In the first noise reduction stage, the airflow enters the air inlet channel 301 and the air outlet channel 401 covered by the soundproof cotton 8, and the medium-high frequency noise is greatly absorbed. In the second noise reduction stage, when the airflow reaches the air outlet 4, the noise adjustment cover 6 has completely moved downwards to cover the air inlet, forming a closed chamber. The airflow is forced to change direction and is sprayed out in the form of a jet from the bottom opening 601. Finally, the high-speed airflow vertically impacts the ground, and the sound wave energy is scattered and attenuated by the ground surface, and the horizontal propagation path is cut off.

[0036] In the further actual example of the present application, the elastic supporting mechanism 5 comprises a plug rod 501 penetratingly arranged on the top of the cable rack 2, the top end of the plug rod 501 is fixedly connected with a supporting plate 502, the surface of the supporting plate 502 is covered with an anti-skid silica gel layer, the plug rod 501 is externally sleeved with a top spring 503, and the two ends of the top spring 503 are respectively abutted with the supporting plate 502 and the cable rack 2. Specifically, when the cable is wound on the cable rack 2 after the charging is completed, the cable will be placed on the supporting plate 502, the top spring 503 on the plug rod 501 can buffer the cable, so as to avoid the cable from directly colliding with the cable rack 2, reduce the abrasion of the cable and the cable rack 2, and also avoid the cable from being accidentally bent during the winding process of the cable on the cable rack 2. At the same time, the top spring 503 can reset and lift the supporting plate 502 when the cable is taken off from the cable rack 2, so that the supporting plate 502 on the cable rack 2 can be reset again, and then the position of the mute adjustment cover 6 is automatically adjusted, so as to quickly adjust the noise reduction strategy of the charging pile in the charging and standby states.

[0037] In the further actual example of the present application, the transmission adjustment mechanism 7 comprises a connecting frame 701 slidingly installed on the inner side wall of the pile body 1, one side of the connecting frame 701 is connected with the plug rod 501, and the other side is in transmission connection with the mute adjustment cover 6. Specifically, when the cable is wound on the cable rack 2, the cable will be lapped on the supporting plate 502, and the vertical downward pressure is applied to the cable to compress the top spring 503, so that the supporting plate 502 drives the plug rod 501 to move downward, and the bottom end of the plug rod 501 pulls the transmission adjustment mechanism 7, so that the transmission mechanism converts the force motion into the lifting action of the mute adjustment cover 6, so that the air inlet 3 and the air outlet 4 are exposed, and standby heat dissipation is realized. When the cable is taken off from the cable rack 2 for charging, the supporting plate 502 is no longer subjected to the pressure applied by the cable, and is reset and lifted under the action of the spring force, so that the plug rod 501 pushes the transmission adjustment mechanism 7 to reversely act to make the mute adjustment cover 6 descend. At this time, the mute adjustment cover 6 completely moves downward to cover the air inlet 3 and the air outlet 4, and the fan in the charging pile also runs at high speed along with the switching of the charging state. The high-speed airflow is sequentially discharged through the air outlet channel 401 and the mute adjustment cover 6, the soundproof cotton 8 in the air outlet channel 401 absorbs most of the high-frequency noise, the closed mute adjustment cover 6 blocks and breaks the remaining noise level propagation, is guided to be downwardly sprayed and impacts the ground surface to scatter and reduce a part of sound energy, so that the noise of the charging pile in the charging state is greatly reduced.

[0038] In the further actual example of the present application, the inner wall of the air inlet 3 and the air outlet 4 is rotatably connected with a transmission gear 702, a driving rack 703 vertically arranged on the connecting frame 701 is engaged with the transmission gear 702, and the inner wall of the mute adjusting cover 6 is fixedly connected with a driven rack 602 engaged with the transmission gear 702. Specifically, the gear is fixed in the pile body 1 through a rotating shaft, the vertical movement of the connecting frame 701 is converted into the reverse vertical sliding of the mute adjusting cover 6, the cable presses down the supporting plate 502, the plug rod 501 moves downward to compress the top spring 503, and the mode switching is completed only by the gravity of the cable and the spring energy storage, so as to reduce the energy consumption. The displacement of the elastic supporting mechanism 5, the transmission adjusting mechanism 7 and the mute adjusting cover 6 is strictly consistent, so as to avoid the out-of-control of the air outlet adjusting, the top spring 503 always provides a reset force, and the position of the mute adjusting cover 6 can be quickly adjusted when the charging pile is switched from the charging state to the standby state, so as to ensure that the airflow can quickly pass through the charging pile after the energy consumption of the fan operation is reduced, and the heat dissipation efficiency of the charging pile in standby state is ensured.

[0039] In the further actual example of the present application, the air outlet channel 401 is rotatably connected with an impeller 403 near the air outlet 4, the blades of the impeller 403 are provided with sound absorbing layers 404 on both sides, and the air outlet channel 401 is fixedly connected with an arc-shaped sound absorbing pad 405 below the impeller 403. Specifically, the installation position of the impeller 403 is at the end of the air outlet channel 401 and close to the air outlet 4, the blades are covered with sound absorbing layers on both sides, the arc-shaped sound absorbing pad 405 is fixed below the impeller 403, the curvature radius thereof matches the swept trajectory of the impeller 403, and a gap is reserved between the arc-shaped inner wall of the impeller 403 and the arc-shaped sound absorbing pad 405. The airflow discharged through the air outlet channel 401 drives the impeller 403 to rotate, and the continuous vortex is crushed into micro-scale airflow, the rotating impeller 403 realizes the micro-control of the airflow, breaks through the frequency limitation of the static noise reduction part, and the gap between the impeller 403 and the arc-shaped sound absorbing pad 405 is accurately matched, so as to avoid friction and improve the sound absorption effect.

[0040] In the further actual example of the present application, the inner wall of the air exhaust channel 401 is hinged with a baffle plate 406 above the impeller 403, and the other side is symmetrically fixedly connected with a sliding block, a sliding groove matched with the sliding block is vertically arranged on the inner wall of the pile body 1, the top of the sliding block is fixedly connected with a compression spring connected with the sliding groove, and one pair of wedge-shaped top blocks 704 abuttingly matched with the baffle plate 406 is fixedly connected to the inner side of the connecting frame 701. When the cable is overlapped on the elastic supporting mechanism 5, the baffle plate 406 is matched with the inner wall of the air exhaust channel 401 on one side. When the cable is away from the elastic supporting mechanism 5, the connecting frame 701 pushes the baffle plate 406 from below to above with the wedge-shaped top block 704 and makes it inclined. Specifically, in the standby state of the charging pile, the elastic supporting mechanism 5 is pressed to make the connecting frame 701 in the transmission adjusting mechanism 7 move downward. At this time, the wedge-shaped top block 704 is located below the baffle plate 406, the side of the baffle plate 406 facing away from the air discharge direction is matched with the inner wall of the air exhaust channel 401, the extra wind resistance structure in the air exhaust channel 401 is eliminated, the reserved air exhaust area between the impeller 403 and the baffle plate 406 is ensured, part of the airflow in the standby state can be quickly discharged without passing through the impeller 403, which is more conducive to natural heat dissipation and reduces standby power consumption. When the cable on the cable rack 2 is removed for charging, the connecting frame 701 pushes the baffle plate 406 from below to above with the wedge-shaped top block 704, so that the baffle plate 406 gradually inclines in the air exhaust channel 401, and the discharged airflow is concentrated to impact the side of the impeller 403 close to the arc-shaped sound-absorbing pad 405, so that the airflow with noise is discharged through the arc-shaped inner wall of the arc-shaped sound-absorbing pad 405, and the impeller 403 is forced to accelerate by the baffle guide, so that the vortex cutting efficiency of the impeller 403 is greatly improved, and the noise reduction effect is remarkable.

[0041] In the further actual example of the present application, the both sides of the pile body 1 are hinged with noise reduction sealing cover plates 9, a plurality of sound-absorbing strips 901 are mounted on the inner side of the noise reduction sealing cover plates 9 along the airflow direction, specifically, the noise reduction sealing cover plates 9 on both sides can realize auxiliary noise reduction function through the plurality of sound-absorbing strips 901 when being closed, and the internal structure of the charging pile can be conveniently overhauled and maintained after the noise reduction sealing cover plates 9 are opened. The position of the noise reduction sealing cover plate 9 is the position of the general louver heat dissipation window in the prior art, which is now improved to be the noise reduction sealing cover plate 9 capable of realizing full sealing state on the upper half of the pile body 1, so as to reduce the height of noise propagation. The noise reduction sealing cover plate 9 is convenient to open, and it is also convenient to add and replace the sound-absorbing strips 901.

[0042] In the further actual example of the present application, the pile body 1 is provided with a sound insulation baffle 10, the exhaust air passage 401 is between the sound insulation baffle 10 and the noise reduction sealing cover plate 9, and the sound insulation baffle 10 is embedded with a plurality of sound insulation cottons 1002, specifically, the sound insulation baffle 10 is vertically fixed in the pile body 1 and parallel to the noise reduction sealing cover plate 9 to form a sound insulation air duct, part of the airflow enters the exhaust air passage 401 after being blocked by the sound insulation baffle 10, and the other part passes through the sound insulation cotton 1002 to enter the exhaust air passage 401, the two parts of the airflow are synchronized to realize efficient cooperation of noise reduction, and the exhaust air passage 401 formed by the sound insulation baffle 10 and the noise reduction sealing cover plate 9 is a sound insulation air duct, which realizes multi-stage sound insulation through the sound insulation cotton 8 covered by itself, the sound absorption strips 901 in the noise reduction sealing cover plate 9 and the sound insulation cotton 1002 in the sound insulation baffle 10, greatly reduces the noise mixed in the airflow during discharge, and realizes self-adaptive noise reduction through material gradient design and structure optimization.

[0043] In the further actual example of the present application, the pile body 1 is provided with a sound insulation baffle 10, the exhaust air passage 401 is between the sound insulation baffle 10 and the noise reduction sealing cover plate 9, and the sound insulation baffle 10 is embedded with a plurality of sound insulation cottons 1002, specifically, the sound insulation baffle 10 is vertically fixed in the pile body 1 and parallel to the noise reduction sealing cover plate 9 to form a sound insulation air duct, part of the airflow enters the exhaust air passage 401 after being blocked by the sound insulation baffle 10, and the other part passes through the sound insulation cotton 1002 to enter the exhaust air passage 401, the two parts of the airflow are synchronized to realize efficient cooperation of noise reduction, and the exhaust air passage 401 formed by the sound insulation baffle 10 and the noise reduction sealing cover plate 9 is a sound insulation air duct, which realizes multi-stage sound insulation through the sound insulation cotton 8 covered by itself, the sound absorption strips 901 in the noise reduction sealing cover plate 9 and the sound insulation cotton 1002 in the sound insulation baffle 10, greatly reduces the noise mixed in the airflow during discharge, and realizes self-adaptive noise reduction through material gradient design and structure optimization.
